Abstract

The utility model discloses an arc urinary anastomotic operating needle, comprising a needle tip and a needle rob, wherein the needle tip is bended in an arc shape, a threading hole is arranged on the needle tip, and a cystoscope is fixed arranged on one end of the needle rob which is close to the needle tip. When in the process of the operation, the thread can be pulled out easily by a barbed needle, and operators are not need to sense the position of the needle through the other cut when in anastomosis, thereby avoiding the infectious diseases which use blood as spread carrier, and simplifying the operation process. The utility model only can cut perineal portion without incising urinary bladder, which has small wound, and the patient can recover fast. Doctors can seen proximal urinary under the vision of the cystocscope, thereby avoiding from injuring the surrounding normal organ, and increasing the efficiency and the success rate of the operation. A fixed device for the cystoscope is spot welded on the needle, and the outer surface of the fixed device is polished finely, which avoids the injury for tissues when in operation.

Description

Arc urethra anastomosis operation needle

Technical field

This utility model relates to a kind of urethra anastomosis operation needle, particularly a kind of arc urethra anastomosis operation needle.

Background technology

The heavy anastomosis operation of operation on urethra, particularly urethral stricture section excision is being selected suitable otch, and under the good situation about exposing, excision narrow section urethra and scar tissue on every side thereof are made the everting suture art of urethra two broken ends of fractured bone with absorbable suture under tension-free situation.Posterior urethral stricture can be selected through abdominal part pubis upper cut, and cut-out pubic symphysis portion is to reach good appearing in case of necessity, and the ball membranous urethra can be selected for use through perineum arc or straight cut.The posterior urethral stricture resection and anastomosis is the operation of comparison difficulty, and surgical needles is being coincide in abdomen perineum wound, and is visual poor because operating field is little, need cut perineum simultaneously and bladder just can undergo surgery, the increase wound face.Operation adopts staight needle to coincide in the prior art, little and be not very clearly under the situation at operating field, can't pass through other apparatus,, increase no small operating difficulty such as the line hook being gone out with crochet hook, need the operator when coincideing, to feel the position of pin by other otch with hands, this process of operation by rule of thumb, not only surgical wound surface is big, the technical difficulty height, the also as easy as rolling off a log finger tip that punctures the operator is the infection of the infectious disease of transmitting carrier and cause with blood.Simultaneously, because operating field is little, sight line is unintelligible, causes the damage of normal surrounding tissue easily, and reduces success rate of operation.

Therefore, need a kind of operation needle, carrying out operation on urethra, when particularly the excision of urethral stricture section weighs anastomosis operation, it is relatively easy to coincide, and can with crochet hook the line hook be gone out easily in sewing process, and not existing with blood is the infectious danger of infectious disease of transmitting carrier, the whole surgery process is only cut an otch, and can make operating field clear.

The utility model content

The purpose of this utility model is to provide a kind of arc urethra anastomosis operation needle, carrying out operation on urethra, when particularly the excision of urethral stricture section weighs anastomosis operation, in sewing process, can with crochet hook the line hook be gone out easily, do not need the operator when coincideing, to feel the position of pin by other otch with hands, simplified the operating process that in the limited operation open country, undergos surgery, during operation in limited operating field space, make operating field clear, only need not cut bladder at perineal incision, wound is little, and the patient recovers soon, improves the success rate and the efficient of operation.

Arc urethra anastomosis operation needle of the present utility model comprises shank, is arranged on the needle point of shank one end, and described needle point is convexly curved, and needle point is provided with through wires hole, and shank is set with cystoscope near needle point one end, and cystoscope endoscope is directly to needle point.

Further, described shank front end is provided with positioning sleeve, and cystoscopic endoscope passes positioning sleeve and aims at needle point, and the shank rear end is fixed on shank on the handle by the hold-down screw that is spun on the handle;

Further, the arcual width of described needle point is 6-10mm, highly is 2-4mm;

Further, the distance of described cystoscopic endoscope and needle point is 1-5mm;

Further, the arcual width of described needle point is 8mm, highly is 3.5mm;

Further, the distance of described cystoscopic endoscope and needle point is 8mm;

Further, described positioning sleeve point is welded in the shank front end.

Arc urethra anastomosis operation needle of the present utility model, needle point is convexly curved, carrying out operation on urethra, particularly the excision of urethral stricture section weighs anastomosis operation, when the urethra end coincide, in sewing process, under the cystoscope direct-view, help the line hook being gone out with crochet hook, do not need the operator when coincideing, to feel the position of pin by other otch with hands, avoided with blood is the infection of the infectious disease of transmitting carrier, simplified the operating process that in the limited operation open country, undergos surgery, avoid in the effective surgery open country, normal surrounding tissue being caused damage, increase work efficiency; Be installed with cystoscopic endoscope near the needle point place, cystoscope is parallel with shank, and volume is little, the time do not disturb operating field in operation, exceed and take the operating field space, can under the cystoscope direct-view, see the near-end urethra, avoid normal surrounding tissue is caused damage, only need not cut bladder at perineal incision, wound is little, and it is fast that the patient recovers, thereby improve the efficient and the success rate of operation, cystoscopic fixture point is welded on the pin, and the appearance correct grinding damages tissue when avoiding performing the operation.
