Description

The medical operation electric knotter

This utility model is the medical operation electric knotter, belongs to medical apparatus and instruments, is specially adapted to inaccessiable deep surgical ligation.

Present operation generally strikes knot with the hand, for fat, otch dark and the operation that is difficult to appear, row organizes ligation very difficult, influences the accuracy and the speed of ligation.Sometimes with enlarging otch or pressing from both sides and finish, increased damage, increased the weight of patient's misery but enlarge otch with silver, titanium.With silver, titanium folder cost height, make in the metallic foreign body long-term storage patient body, take off folder, volume in addition greatly and the shortcoming that should not frequently use.

The purpose of this utility model be to overcome above-mentioned weak point of the prior art and provide a kind of carry silk thread volume, guide rod wired, send knot, lastex need not enter not damaged medical operation electric knotter in the wound with hands freely.

The purpose of this utility model realizes by following measure:

This utility model is by battery, motor, actuating device, around wire-sending device, manipulation device, housing and bulb are formed, actuating device comprises worm screw, rotating shaft, worm gear and flap, the worm screw of being fixed on the motor shaft is meshed with worm gear on being fixed in rotating shaft, comprise coil around wire-sending device, stainless steel ring and guide rod, housing comprises shell, shell axle bed and swivel base, the shell extension has bulb and guide rod, the guide rod end has through wires hole, fixedly deposit flap in the rotating shaft on worm gear right side successively, be connected with coil and stainless steel ring, manipulation device comprises button, spring, switch, normally closed switch, driving lever, shell fragment and elastic pressuring plate, the stainless steel ring left side has driving lever and right side that shell fragment is arranged, driving lever top cementation has shell fragment, driving lever middle and upper part cementation has switch, the driving lever middle and lower part adheres on the swivel base axle, and there is spring the driving lever lower end, and the elastic pressuring plate lower end that adheres on the normally closed switch is fixed on the swivel base, the upper end is from the button section of having small distance, motor both positive and negative polarity, battery, normally closed switch and switch constitute closed circuit.

Fig. 1 is total figure of the present utility model.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing: motor 1 adheres on the shell 2, and worm screw 3 is fastened on the motor shaft, is meshed with worm gear 5 on being fastened on rotating shaft 4, and rotating shaft is rotatable on enclosure axis seat 19.Be fixedly connected sequentially in the rotating shaft on worm gear right side flap 11, be connected with coil 14 and stainless steel ring 15, flap right side and coil left side cementation friction plate, steel loop 15 is fixed on the coil 14.There is driving lever 12 left side of steel loop 15, and there is shell fragment 13 right side, the top of shell fragment 13 cementation driving levers 12.The right side cementation switch 8 of driving lever middle and upper part, there are spring 10 and button 9 in the switch right side, and the button right-hand member stretches out in outside the shell.The right side of driving lever middle and lower part adheres on the axle of swivel base 20, and there is spring 21 on right side, driving lever lower end, and spring 21 right-hand members peak at the shell inboard.There is normally closed switch 7 to adhere to the shell inboard between swivel base 20 and the button 9, the flexible tabletting 16 of normally closed switch left end, tabletting 16 lower ends adhere on the swivel base, and the upper end is positioned at the button left side and from the button section of having small distance, present embodiment is 4 millimeters.There is battery 6 the motor below, and total power switch 25 is arranged between motor and the battery.Extension bulb 24 on the shell and guide rod 18, guide rod right-hand member are connected on the screw 22 of extension, and the guide rod left end has through wires hole 23, and guide rod can be made the polytype of different length and difference in functionalitys such as cover line, trimming.Knotting is around on the coil 14 with an end of line, and the end in addition of line passes through hole 17 and hole 23, the usefulness that supplies the guide rod line sending and entangle the tissue that needs ligation.The both positive and negative polarity of motor, battery, normally closed switch and switch constitute closed circuit, and the both positive and negative polarity of battery is also in parallel with bulb.

During use, total power switch is pressed by elder generation, presses button 9 more gently, rotates with starter motor by spring 10 compressing switches 8, and worm screw drives worm gear and rotating shaft is rotated, and at this moment, the coil and the stainless steel ring that are set in the rotating shaft are not followed the rotating shaft rotation.When need carry out ligation to tissue, hand-held housing is stretched to tissue and is further pressed button 9 together with guide rod, driving lever and shell fragment clamping stainless steel ring are moved to the left, make friction plate on the coil be adjacent to friction plate on the flap, coil rotates with rotating shaft and flap, and the guide rod line sending is also entangled the tissue that needs ligation.Release button also outwards shifts out guide rod, at the following knot of making a call to of the very little state of wire-drawing tension.Gently press button then, coil rotates stringing, and guide rod stretches to tissue and send and tie ligation place stringing, further press button, move to left and touch normally closed switch 7 and cut off the power supply because button 9 is oppressed tablettings 16, motor is braked together with the coil stall, to strengthen stringing power, first knot has been beaten.Make a call to second knot, the 3rd knot successively by above-mentioned steps then ... or the like and to finishing.Bulb 24 illuminations are arranged in order to operation.

Implement and clinic trial by animal, respond well.

The utility model compared with prior art has following advantage:

(1) only needs the little knotter of a volume, carry the coil of wire and complete by the guide rod of knotter Become the line sending ligation, saved in the past deep ligation at every turn with clamp line, line sending, go to clamp and carry again line The process of ligation has improved ligation speed.

(2) this knotter only needs guide rod to enter the ligation position. Electronic stringing need not enlarge and cut Mouthful, ligation is accurate, has reduced patient's misery.

(3) tension force is very little during the wire twister loose ends, only arrives ligation place stringing, for skilled surgeon not too, can not damage the ligation tissue because of the ligature tractive.

(4) guide rod is dissimilar, and multiple functions such as cover bundle and trimming can be arranged, and can finish the surgical ligation that prior art can not be finished.

(5) this wire twister silk thread ligation, than low with metal costs, volume is little, and is little to the human body stimulation, and do not retain metallic foreign body in vivo.
