Description

A kind of Pisces card tissue holder

Technical field

The present invention relates to a kind of surgical operation medical assistance apparatus, for the folder of closed blood vessel or tissue in especially a kind of surgical procedures, be usually also called vascular clamp or ligation clip.

Background technology

In the mirror surgical procedures of chamber, need to close the fracture blood vessel in otch, hemorrhage to stop.Carry out ligation with stitching thread again after clamping fracture blood vessel with mosquito forceps, and be not suitable for the fast and convenient requirement of chamber mirror surgical operation.Adopt the hemostasis tissue holder extensive use of polymeric material.Tissue holder comprises the V-arrangement clamp of the first arc jig arm and the second arc jig arm one formation, the free end of the first arc jig arm and the second arc jig arm is respectively grab and card convex, by one " hinge " Structure composing between first arc jig arm and the second arc jig arm, hinge structure is as follows: the junction of the first arc jig arm and the second arc jig arm by inside and outside two connector bifurcateds formed, be a hole between inside and outside two connectors, when the first arc jig arm and the second arc jig arm one form V-arrangement clamp, this hole is U-shaped.When the grab of the free end of the first arc jig arm and the second arc jig arm and card convex close, tissue holder is the closed hemostasis of a shape, the arc stress of the first arc jig arm and the second arc jig arm makes grab and card convex tight connecting, consider to can not make its downright bad or operation to the pressure of biological tissue, a slit can be left between general two jig arm, the nip surface of jig arm can be provided with some profile of tooth districts, makes biological tissue and jig arm form larger frictional force.

Tissue holder is provided with three to five specifications of the different size of size, is provided with the special applicator of series and gets binder, for using the tissue of different specification size.Applicator and get binder and all have long handle, can apply in the mirror surgical operation of chamber.Certain tissue holder also can be metal material or absorbable material preparation.

The open and more perfect such scheme of prior art, Ye Shi hospital equips the operation auxiliary equipment of use in a large number.Typical Chinese patent and patent application have: CN201110023843, and 201310334138 and 201410777554; But prior art still Shortcomings: although the reliability of clip (seamed on clip) has been fine, but in practical operation, doctor is generally also needed to apply second clip, sometimes the position that tissue cut stump stays is difficult to use second folder, as required to clamp completely, or when requiring higher reliability, second clip is that doctor often adopts; The applicator front end of the existing clip that chamber mirror surgical operation uses (is provided with metal jaw, vise knuckle force, because the wide 1mm of only having of tissue holder is even narrower) be full parcel to tissue holder, although lead mirror (or special image harvester) in use as observation window.But impact is still had on surgical field of view, all armrest senses sometimes during applicator blocking-up blood vessel.US2005/0171560A1 discloses the structural representation of applicator.

Stay when many clips are longer in the body of uke, run into folder and close tremulous pulse or significant points blood vessel, condition is with when being permitted, and doctor all can select the double fastener insured, but retain too short position for vessel stump, existing product and technology cannot be pressed from both sides and be closed twice independently clip simultaneously.

The tissue holder of prior art is single folder or single design, tissue holder sidepiece is provided with the supported end of knuckle as Clip Applier or applicator, the outer rim rectangular angular of knuckle and folder easily causes friction and damage to blood vessel perienchyma, and especially lobe of the lung patients after surgery there will be cough bleeding; It is by grab and card convex that the folder of its jig arm head closes, card convex is the formation that raises up that jig arm (the second arc jig arm) both sides are provided with, the cross section of card convex bottom center is the wedge mated with grab, card convex is that jig arm is only pinning/occlusion and does not have the dual guarantee of " lock " and " button ", free not totally or larger blood vessel for tissue, easily " collapse out ", have not clamping worry.Tissue (as blood vessel) comparatively slightly maybe cannot clamp or not clamping (as shown in Figure 9).

Its two jig arm cross sectional shape is rectangle (edge is slightly through polishing), cannot change ellipse into, presss from both sides after changing ellipse into because single, because external force (vertical Pressure value or level peel off resistance during blood vessel) easily produces torsion and is out of shape when folder closes.

Designing for drops of card convex both sides projection, there is when folder closes navigation force effect (being also called knuckle), but getting in nail (nail is being commonly called as of tissue holder) incorrect situation, or when blood vessel is totally free or blood vessel is excessively thick, single nail clip is closed yielding, the design of water droplet, and tip is hard not, can not efficient navigation, thus there is the phenomenon that nail clip is disconnected;

The one-sided folder of general blood vessel is closed use 2 clips, small size wide (jig arm+knuckle) 2mm, in, the wide 3mm of large size.2 clip can not stick together when closing, because mutually extruding sideslip can be produced, simultaneously because the restriction of operating theater instruments, doctor's maneuver and single folder knuckle projection also causes 2 clips well not stick together, so in theory, press from both sides two single folders, at least need the distance of 2mm+2mm+1mm (2 folder spacing)=5mm or in, large size needs the distance of 3mm+3mm+1mm (2 folder spacing)=7mm.

Previously folder 2 clips, so-called double insurance in fact and non insurance because once tremulous pulse washes 1 clip open, another clip relative to the clip be rushed to open before, on Pressure value degree and anti-skidding on character without any difference, so dangerous; And usually use 1 clip to close the situation of blood vessel, mostly be because vessel stump (cuff length) is too short, or can perform the operation that free blood vessel exposes not meticulous fast for the too narrow and small or doctor of folder closed region and cause cannot be many, be not because use one just much of that.

Also have; existing Clip Applier is that parcel clip carries out clamp, closes by clip; the visual field is unintelligible, cannot see whether blood vessel presss from both sides intuitively and close, especially for free not totally or excessively thick blood vessel; often there will be the phenomenon of " false folder closes "; to occur in art, postoperatively to collapse out, the hemorrhage fatal phenomenon such as slippage, especially postoperatively to collapse out; very easily cause the second operation that death or infection cause, this belongs to malpractice.In addition, it is be made up of grab and card convex that the tissue holder folder of prior art closes, but still leaves some room for improvement.Card convex is the formation that raises up that jig arm (the second arc jig arm) both sides are provided with, the cross section of card convex bottom center is the wedge mated with grab, totally or larger blood vessel not clamping worry is not had before " collapsing out " for tissue is free, and more difficult discovery.

Summary of the invention

The present invention seeks to, provide a kind of Pisces card tissue holder, to overcome or to avoid the problems referred to above.Pisces card structure, greatly simplify the deficiency that the design of card convex and knuckle may be brought, can by suitably increasing the use that width does not affect applicator, meet the instructions for use (mainly diameter meets the demands) of chamber mirror, can clamp completely, and there is higher reliability, easily be prepared into the two tissue holder of Pisces card, doctor often applies once to adopt double end tissue holder, is equivalent to be applied with two tissue holders.In most cases, it is useful and harmless for applying double fastener simultaneously.

For solving prior art problem, technical solution of the present invention is, Pisces card tissue holder, each tissue holder comprises the V-arrangement clamp of the first arc jig arm and the second arc jig arm one formation, the free end of described first arc jig arm and the second arc jig arm is respectively grab and card convex, and grab and the shape of card convex are that the Pisces shape mutually mated after engaging hooks.

After engaging, Pisces shape hooks is rounded and quasi-circular (with Tai Ji shape or similar Tai Ji shape, having gentle circular arc, except linking arm).Pisces shape hooks and forms Pisces card.

Grab and card convex be hook groove each other, and grab position is that fish shape is protruding, and card convex part cervical region has recess to coordinate the protruding grab of accommodation fish shape, and the cervical region recess of grab coordinates again the bossing of card convex.

Fish shape protruding or/carry out engaging contact surface with the recess holding fish shape projection grab to be provided with slip shallow slot structure along engagement direction.The both sides card convex of grab enters engaging place and is provided with projection i.e. auxiliary guide pad.Protruding auxiliary guide pad is simultaneously as the stress point (can be described as knuckle) of applicator.

Be provided with two Pisces card tissue holders and for side by side configuration, described each tissue holder comprises the V-arrangement clamp of the first arc jig arm and the second arc jig arm one formation, the free end of described first arc jig arm and the second arc jig arm is respectively grab and card convex, by one " hinge " Structure composing between first arc jig arm and the second arc jig arm, forming V-shape clamp when the first arc jig arm and the second arc jig arm free state; The nearly grab adjacent side in the first arc jig arm adjacent inboard face is connected, and forms the 3rd connecting rod that two tissue holders carry out connecting; Two tissue holders are provided with two card convexs corresponding with grab, and the adjacent inboard face between two card convexs is provided with the position that raises up and connects the 4th connecting rod then forming two tissue holders and carry out connecting, and the third and fourth connecting rod is the supported end of Clip Applier.

4th connecting rod that is between two card convexs two of adjacent side raise up, be merged into middle one and raise up, namely only adopt one and raise up, lead to two grabs simultaneously.

The adjacent side of the first arc jig arm or the second arc jig arm and hinge adjacent place is provided with first and/or second (one to two) connecting rod;

Grab card convex is fish shape.But the arc shape connected is same as the prior art or similar.

1.5-3mm is greater than when two tissue holders are designed to interval; Three, the 4th connecting rod is provided with the point of application of applicator.Be greater than 1.5-3mm when two tissue holders are designed to interval, it is the structure of widening that one, centre raises up; One, centre raises up and is provided with groove, is namely provided with the supporting groove of applicator.

In, namely the jig arm of large size duplex tissue holder follow closely the interval 2mm that lower limb is of a size of 2*1mm+ the 3rd and the 4th connecting rod (can cross section overstriking), altogether=4mm.

First to fourth connecting rod of two tissue holders forms knuckle in the outside of two tissue holders projection, is the point of application of applicator; Third and fourth connecting rod can in rectilinear direction along stretching out the lateral surface of arc jig arm as the second knuckle, as the force of applicator.

The nip surface of jig arm is provided with some " Eight characters " anti-skidding profile of tooth district 8, and the tooth in the anti-skidding profile of tooth district 8 of every tissue holder is oblique line shape.Profile of tooth district after two tissue holder clampings is some "eight" shape; Every bar oblique line shape tooth be divided into upper and lower two-section, upper and lower two-section oblique line shape tooth is straight line tooth or staggered tooth.

4th connecting rod very in short-term, is then that two of inner side raise up between two card convexs, can be merged into middle one and raises up, namely only adopt one and raise up, can lead to two grabs simultaneously.Be greater than 1.5-3mm when two tissue holders are designed to interval, the 4th connecting rod is the structure of widening, and cross section can also increase; 4th connecting rod is provided with groove, is namely provided with the supporting groove of applicator.

Grab and the shape of card convex are that the Pisces hook that mutually mate after engaging or Tai Ji hook, and can be circle or oval; Grab position is fish shape.But the arc shape connected is same as the prior art or similar.

There is provided a kind of duplex or double end tissue holder, to overcome or to avoid the problems referred to above.The duplex of integration or bipitch structure, surmount and possess the function of two clips in parallel, and width does not affect the use of applicator, meet the instructions for use (mainly diameter meets the demands) of chamber mirror, can clamp completely, and there is higher reliability, doctor often applies once to adopt duplex or double end tissue holder, is equivalent to be applied with two tissue holders.

Two clips in parallel and double joint sandwiched meter, knuckle can interior namely not protruding, and the connecting rod between two folders is knuckle, and knuckle can be the supporting force of applicator equally, and knuckle not easily causes damage to blood vessel interior; Due to " double end/both arms " design, add that both arms turn increase three or four connecting rods, make the structure of double end tissue holder from 2 points, become 4 supports, distortion resistance increases, and both arms extension cross section becomes elliptical deformation for possibility from square.

Both arms middle brace rod can carry out overstriking design, rock-steady structure, after both arms snap close, by the restriction of middle brace rod, there will not be the situation of distortion of vacillating now to the left, now to the right.

" double end tissue holder " is not only simple " 1+1 ", because double end tissue holder organizational structure is stablized, blood vessel impacts the Pressure value amount being equivalent to impact 2 times, instead of washes 1 open and reopen 1 clip again, just needs the strength of reopening 1 times all the time.In addition, the both arms gap of double end tissue holder leaves sufficient space to blood vessel, ensure that the activity of blood vessel, simultaneously because blood vessel when folder closes receives extruding, blood vessel in the middle of both arms is raised in both arms, serves the effect of good anti-sideslip, so the Pressure value amount of double end tissue holder is the 1*2 of old clip, anti-sideslip strength is " 1+1 " >2, the simultaneously also additional resistance >3 of both arms gap blood vessel.

The Clip Applier that easy design is novel, the folder of new Clip Applier closes, and executes position i.e. connecting rod 11, simultaneously design of employing T-shape inside both arms of getting and following closely and putting forth effort, ensure that and get the stable of nail and the visual field, clearly can see that folder closes result completely.

Beneficial effect of the present invention: the design of Pisces type or " Tai Ji " Pisces type tissue holder, both the damage of sharp-pointed ailhead to tissue had been avoided, close relative to the easier smooth and easy folder of tip " snap close " of old-fashioned ailhead, avoid pressing from both sides and to there will not be when closing under abnormal conditions because ailhead resistance causes pressing from both sides the situation of closing the distortion fracture that has some setbacks; Meanwhile, " Tai Ji " fish shape is designed, and has not only pinned, and completes the closed of two, more by large outer little in the inner, and reaches the effect of " button ", time the nail clip probability that collapses out less.(digital flexion, on the other hand just to oneself, opposes oneself, the shape interlocked on the other hand); Clamp design is more reasonable, and the reliability of snap close increases, and avoids the damage of sharp-pointed ailhead to tissue.

By providing a kind of duplex or double end Pisces tissue holder, to overcome the deficiency of existing tissue holder.The duplex of integration or bipitch structure, possess and surmount the function of two tissue holders in parallel, and width design does not affect the use of applicator, meet the instructions for use (mainly diameter meets the demands) of chamber mirror, can clamp completely, and there is higher reliability, doctor often applies once to adopt double end tissue holder, is equivalent to be applied with two tissue holders.In most cases, it is useful for applying double fastener simultaneously.Double end Pisces tissue holder does not generally need to adopt guiding auxiliary block.

Two clips in parallel and double joint sandwiched meter, knuckle can interior namely not protruding, and the connecting rod between two folders is knuckle, and knuckle can be the supporting force of applicator equally, and knuckle not easily causes damage to blood vessel interior; Due to " double end/both arms " design, add that both arms turn increase three or four connecting rods, make the structure of double end tissue holder from 2 points, become 4 supports, distortion resistance increases, and both arms extension cross section becomes elliptical deformation for possibility from square.

Both arms middle brace rod can carry out overstriking design, rock-steady structure, after both arms snap close, by the restriction of middle brace rod, there will not be the situation of distortion of vacillating now to the left, now to the right.

Double end tissue holder is owing to can lack knuckle in the outside of folder, simultaneously by the folder spacing of having fixed two folders, so in, large size double end organizes clip nail lower limb 1mm*2+ cross section overstriking connecting rod 2mm=4mm, fewer than traditional method 3mm, save a large amount of vascular clamp usage spaces, this is very large progress for endoscope-assistant surgery vascular ligation technology! The length of vessel that small size double end tissue holder needs also than original few may at 3.5mm, than original few 1.5mm.

" double end tissue holder " is not only simple " 1+1 ", because double end tissue holder organizational structure is stablized, blood vessel impacts the Pressure value amount being equivalent to impact 2 times, instead of washes 1 open and reopen 1 clip again, just needs the strength of reopening 1 times all the time.In addition, the both arms gap of double end tissue holder leaves sufficient space to blood vessel, ensure that the activity of blood vessel, simultaneously because blood vessel when folder closes is squeezed, blood vessel in the middle of both arms is raised in both arms gap, serves the effect of good anti-sideslip, so the Pressure value amount of double end tissue holder is 2 times of old clip, anti-sideslip strength is " 1+1 " >2, the simultaneously also additional resistance >3 of both arms gap blood vessel.

The Clip Applier that easy design is novel, the folder of new Clip Applier closes, execute to get and follow closely the position of putting forth effort i.e. connecting rod 2,2-1 (knuckle being included in this position is namely protruding) inside both arms end, adopt T-shape design simultaneously, ensure that and get the stable of nail and the visual field, clearly can see that folder closes result completely.
