Description
Technical field
The present invention relates to medical instruments field, and in particular to a kind of more indicating window tube type anastomats.
Background technology
Tube type anastomat is suitable for middle esophagus, Stomach duodenum, small intestine, colon and rectum etc. and holds end, side and side side kiss
Used during conjunction.It coincide especially suitable for appearing with the esophagus of operating difficulties, stomach and stage casing resection of rectal postcolon rectum low level
End to end anastomosis.
Tube type anastomat has more than 40 years history applied to reconstruction operations, is generally to be used in reconstruction operations at present
A kind of surgical operating instrument.The product uses stapler principle, is in staggered identical pin by prolonging two row of tubular peripheral,
The docking that coincide is carried out to internal organs in operation.Stapler is in the same size with previous anastomotic footpath, and mucous membrane pairing is neat, previous anastomotic fastness
Reliably, haemostatic effect and blood transport the advantages of holding is good and the excision that coincide once is completed, easy to operate.Not only it is substantially shorter
Operating time, reduces amount of bleeding, and operation wound is light, and can improve surgical quality, reduces postoperative complication.
In the operating process that tube type anastomat uses, by the spacing of resist-nailed seat and nail bin to determine whether the own warp of tissue
It is adequately compressed or correctly coincide, this can makes the height of staple meet the needs of destination organization.Therefore, it is necessary to resist-nailed seat and nail
The spacing in storehouse is indicated so that doctor is judged.However, existing tube type anastomat, the indicator to be observed of doctor is located at
In the transparent indication window of firing handle opposite side, as doctor since operation technique or operation require, doctor operates apparatus
When indication window not towards doctor's sight side；Doctor can fire zone in order to which whether viewer body rotates to（Green area）, and
Be adjusted to can fire zone, according to tissue thickness green area to instruction pin position be finely adjusted when, very influence doctor to device
The harmony of tool operation（Eye, hand, apparatus, tissue）.Existing tube type anastomat window is small, is unfavorable for doctor's operational observations and refers to
Show pin position, it is inconvenient to use.

On the outside of the instruction unit 63c on right side.Labeling 640 is divided into multiple indicating areas, and the rear and front end portion of indicating window 64 is respectively provided with
The sign 642 of one sign 642, wherein front end is represented after coincideing when resist-nailed seat 2 and larger 3 spacing of seaming and cutting mechanism
Staple shape, staple height is larger；The sign 642 of rearward end represents to kiss when resist-nailed seat 2 and smaller 3 spacing of seaming and cutting mechanism
Staple shape after conjunction, the staple height after coincideing at this time are smaller, more flat.One of indicating area for can fire zone 641,
It is with certain proportion（Such as 1:1 or 2:1 etc.）The spacing of resist-nailed seat 2 and seaming and cutting mechanism 3 is indicated, the height for judging staple for doctor is
The no needs for meeting destination organization.It is described can fire zone 641 may be configured as green, indicateing arm 63 may be configured as red, be easy to
Stapler can be fired by, which more intuitively judging whether, coincide.
As shown in Figure 3,4, indicating mechanism 6 further includes multiple shutters 68 being fixedly installed in shell 1, each shutter
68 correspond to an instruction unit（63a, 63b or 63c）, shutter 68 is arranged on corresponding instruction unit（63a, 63b or 63c）Inner side,
Avoid seeing other components in shell 1 from indicating window 64.The both ends of U-shaped indicateing arm 63（That is, the shutter of the left and right sides
68）On be respectively equipped with two sliding slots 681, sliding slot 681 extends along the longitudinal direction, the both ends of the instruction unit 63a and 63c of the left and right sides
Portion is fixedly connected with fixture block 631 respectively, and each fixture block 631 can be slidably plugged in corresponding sliding slot 681 along the longitudinal direction.U-shaped
The middle part of indicateing arm 63（That is, the instruction unit 63b of upside）Madial wall is equipped with the card slot, and card slot is perpendicular to anteroposterior direction（Tool
Body is along first arc）Extension, the upper end of connecting rod 62 is actively plugged in card slot 631.Indicating mechanism 6 has instruction
State, in instruction state, the connecting rod 62 that pull rod 61 is moved rearwardly into its hook portion 611 and its rear connects, with adjusting rod 4 into
One step is moved after driving pull rod 61, and connecting rod 62 is subject to thrust backward and rotates backward around pivot 621, and indicateing arm 63 moves,
Due to the limitation of two side chutes 681, indicateing arm 63 can only be moved rearwards, from then moving on to positioned at can the inner side of fire zone 641.
The rod spring 622 for being used for resetting connecting rod 62 is equipped between connecting rod 62 and shell 1.Rod spring 622 is specially
The torsional spring being sheathed on pivot 621, one end and connecting rod 62 push against contact, the other end and shell 1 and push against contact.Rod spring
The 622 elastic reset power provided to connecting rod 62 make indicateing arm 63 have the trend moved forward.The indicating mechanism 6 has initial shape
State, in original state, the hook portion 611 and connecting rod 62 of pull rod 61 depart from or connect but do not exert a force to connecting rod 62, in rod spring
Under 622 elastic reset power effect, indicateing arm 63 move forward to indicating window 64 positioned at can be at the front of fire zone 641.
The rearward end of pull rod 61 can be movably attached in adjusting rod 4 along the longitudinal direction, as shown in figure 5, the rear end of pull rod 61
Portion offers hole, and the rearward end of pull rod 61 is slideably sheathed on adjusting rod 4.61 rearward end of pull rod is arranged on 65 He of an adjustment block
Between one adjusting rod spring 67.Adjusting rod spring 67 is sheathed on adjusting rod 4, the rear end of adjusting rod spring 67 and shell 1 connect,
Leading portion and 61 rearward end of pull rod connect.Adjustment block 65 has the slot hole 651 extended along the longitudinal direction, and adjustment block 65 is by being located at length
Screw 66 in hole 651 is connected to adjusting rod 4, and can slide back and forth and be finely adjusted on adjusting rod 4.Pass through survey before dispatching from the factory
Measure resist-nailed seat 2, nail bin（Organize seaming and cutting mechanism 3）Gap, position of the adjustment adjustment block 65 on adjusting rod 4, ensures original state
When, indicateing arm 63 is in 64 default correct position of indicating window（Can the front of fire zone 641）.
For the apparatus of opening, turn butterfly knob 5, adjusting rod 4 is rotated and is moved rearwards, seaming and cutting mechanism 3 and resist-nailed seat 2
Move closer to, the hook portion 611 that pull rod 61 when mechanism is closed into certain position is cut when tissue seaming and cutting is hooked and pushed down by rod spring 622
Connecting rod 62, connecting rod 62 starts to rotate, and under coordinating in 62 end of connecting rod and card slot 631, indicateing arm 63 slides backward, and works as indicateing arm
63 each instruction unit 63a, 63b and 63c instruction to labeling 640 green can fire zone 641, doctor judges rational position,
Stopping rotating, pull lower insurance, fire apparatus, tissue at this moment be able to can be embarked on journey by reasonable squeezing, suture needle to appropriate nail height, this
When can guarantee that Tissue Blood for and can guarantee that tissue not bleeding.
For the apparatus of closure, turn butterfly knob 5, adjusting rod 4 is rotated and moved forward, seaming and cutting mechanism 3 and resist-nailed seat 2
It is gradually distance from, 622 drive link 62 of rod spring is pressed against pull rod 61, drives indicateing arm 63, and indicateing arm 63 slides forwards.
