Abstract

The utility model relates to a knot tying device used for the laparoscopic surgery. The knot tying device adopts a long rod-shaped instrument with a handle at the rear end, a knot tying head is arranged at the front end of the long rod, at least two thread nesting columns are arranged on the knot tying head, the last thread nesting column of the thread nesting columns is fixed, and the rest thread nesting columns adopt telescopic structures. A trigger is arranged at the rear end of the long rod, and is connected with the telescopic thread nesting columns on the knot tying head at the front end through a pulling thread, and resetting springs are installed on the telescopic thread nesting columns. By adopting the knot tying device, double or triple knots are accomplished outside the abdominoscope, but the knots are not tied tightly, are respectively nested on the thread nesting columns and are pushed to the abdominal cavity with the instrument, and then all the knots are tied tightly in sequence through retracting the telescopic thread nesting columns one by one. The two or three times required for pushing the knots outside the original abdominoscope are reduced to once, and thereby the efficiency is improved, and the operation time is shortened.

Description

A kind of wire twister that is used for the surgery laparoscopic surgery

Technical field

This utility model belongs to the medical device technology that uses in the operation, is specifically related to a kind of wire twister that is used for performing the operation and uses.

Background technology

Because laparoscopic surgery can not strike knot with the hand as abdominal, present a kind of way is to avoid the operation of tiing a knot as far as possible, adopts with titanium folder or biological folder and substitutes knotting, and a titanium folder can substitute a toe-in, and this method cost is very high.A titanium presss from both sides about 50 yuans, about 200 yuans of biological folder, and the cost of a toe-in is almost nil.

In order to reduce the operation cost, another kind of way is still the mode that adopts knotting, and a kind of is to tie a knot in peritoneoscope, promptly at intraperitoneal, with the motion of two apparatuses replacement handss, finishes knotting, and this knotting mode craftsmenship is quite high, only is that the superb person of minority technical ability grasps.A kind of is that peritoneoscope is tied a knot outward, promptly beats what a knot (suture once intersects) outside the abdominal cavity, is pushed in the abdomen with apparatus, and removal equipment is made a call to a knot once more outside the abdominal cavity then, pushes intraperitoneal again.A reef knot (minimum requirements of knotting) can be made a call to repeatedly for twice, a triple junction (knot of the common usefulness of abdominal) can be made a call to repeatedly for three times.This mode is low to the specification requirement of knotting, but efficient is lower, has prolonged operating time relatively.

Summary of the invention

This utility model provides a kind of wire twister that is used for the surgery laparoscopic surgery at the deficiency that prior art exists, and to improve knotting efficient, shortens operating time.

The technical solution of the utility model is as follows:

A kind of wire twister that is used for the surgery laparoscopic surgery, it is the elongated rod shape apparatus of a rear end band handle, and the front end of stock is the knotting head, and at least two cover terminals are arranged on the knotting head, and last is fixed in all cover terminals, and remaining is Collapsible structure; The rear end of stock is provided with trigger, and trigger is connected by the scalable cover terminal on backguy and the front end knotting head, on the scalable cover terminal back-moving spring is installed.Adopting above-mentioned wire twister, is to finish a double or triple junction (suture intersects two or three times) outside peritoneoscope, but also it's not serious, be set on the terminal respectively, after pushing the abdominal cavity with apparatus, again by the telescopic cover terminal of withdrawing singly, urgent successively each knot.Like this, original peritoneoscope is tied a knot outward two, three times that need be pushed, be kept to once and finish, thereby raise the efficiency, shorten operating time.

In order to make knotting more firm, the knotting head can be further designed to a tong-like, the rear end is inserted in the perforate of stock front end, the cover terminal is installed in the front end of tong-like knotting head, each cover terminal is divided into two halves, be installed in respectively a tong-like knotting front end about on two arms, be a complete cover terminal after two arms close up, the rear end of stock is provided with a trigger in addition, and trigger is connected by the stretch-draw mechanism of backguy with a tong-like knotting rear end.The effect of tong-like knotting head be in knotting by opening two arms, can help to tighten suture, thereby strain each knot, be tie a knot more firm.

The utlity model has and improve operation efficient, shorten operating time, advantage simple in structure, easy to use.

Description of drawings

Fig. 1 is the sketch map of a kind of structure way of realization of this wire twister;

Fig. 2 is the structural representation of this wire twister knotting open configuration.

Specific embodiments

Referring to Fig. 1 and Fig. 2, this wire twister is the elongated rod shape apparatus of a band handle, the front end of stock 2 is equipped with tong-like knotting 1, tong-like knotting 1 rear end is inserted in the perforate of stock 2 front ends, and the front end of tong-like knotting 1 is equipped with three cylindric cover terminals 3, and each cover terminal 3 is divided into two halves, be installed in respectively tong-like knotting 1 front end about on two arms, be a complete cover terminal after two arms close up, forward two of cover terminal 3 are Collapsible structure, and last is a fixed structure.The rear end of stock 2 is provided with 4, one triggers of two triggers and is connected by the scalable cover terminal 3 on backguy 5 and the front end knotting head, on the scalable cover terminal 3 back-moving spring 6 is installed.Another trigger passes two pulleys 7 on the stock inner hole wall of rear end two arms that are installed in tong-like knotting 1 by backguy 5, and connects two arms of tong-like knotting 1 rear end, forms the stretch-draw mechanism to tong-like knotting head.

During use, after suture passes Intraabdominal knotting position, the two ends of line are caused outside the abdominal cavity, after suture intersects, before toe-in places first cylindric cover terminal 3, intersect to form second knot once more, place second cylindric cover terminal 3 before, before the 3rd toe-in places the 3rd cylindric cover terminal 3.Left hand is caught line, and the right hand is held wire twister, and three knots are pushed the abdominal cavity.After first knot arrived assigned address, cocking 4 made first cylindric cover terminal 3 retractions, draw close pushing away with first knot before second knot, and further again cocking 4, second the cylindric cover terminal 3 that bounce back, backup before the 3rd knot is tight, and knotting is finished.When pro-pushes away, if worry that knotting is not tight, can make tong-like knotting 1 front end make opening movement by pulling another trigger 4, by separating cylindric cover terminal 3 so that line is tightened, it be more reliable to tie a knot.
