Abstract

The utility model relates to a kirschner wire, which belongs to the field of medical devices. The kirschner wire comprises a needle body. The kirschner wire is characterized in that the needle body is provided with a needle point part which is integrally connected; the needle point part is provided with a first needle hole and a second needle hole, which are longitudinally arranged; the needle point part is in the shape of a flat shuttle, and the cross section is arc-shaped. The kirschner wire is advantageous in that the needle point part is in the shape of a flat shuttle, which is pointed but not sharp; hernial sac or vaginal process can be ligated out of a peritoneum, and ligation is complete without any gaps, and thereby damage to tissue is reduced; the needle point part is provided with the first needle hole and the second needle hole, which prevents the friction between wires at the position of the needle hole; the kirschner wire is convenient and practical, economical and easy in the operation process of laparoscope ligation; the side face of the needle point part is arc-shaped, facilitating the dissociation of the kirschner wire in the peritoneum.

Description

A kind of Kirschner wire

Technical field

This utility model relates to medical apparatus, specifically, relates to a kind of Kirschner wire.

Background technology

Indirect inguinal hernia in children is many fails due to obturation because of peritoneum processus vaginalis in period of embryo's testicular descent process, and neonatal period can be fallen ill, and is a kind of congenital diseases.Male is common, and compared with the many 2-3 in left side doubly, bilateral person is rare, accounts for 5%-10%, is one of common disease of pediatric surgery on right side.The common technology of this type of disease for the treatment of is laparoscopic technique at present, and laparoscopic surgery has this innate advantage of operation pathway from inside to outside because of it, and ligation place is highest order certainly, therefore can obtain satisfied effect.When carrying out laparoscopic surgery, need to carry out ligation with needlework, pin for ligation in prior art mostly is other common staight needles, its shortcoming is that end is too sharp, when the operation of the tissue that dissociates, easily tissue is caused to damage, also have the Kirschner wire of some transformations, only have a pin hole more, article two, line can make etween the lines produce friction at a pin hole simultaneously, ligation operation is brought inconvenience, and some crochet hooks both sides are not round and smooth, likely cause tissue injury.Therefore, need a kind of Kirschner wire, can make needle tip sharply not sharp, just can ligation hernical sac or vaginal process outside peritoneum, and be Complete Ligation, do not stay gap, and there are two pin holes, avoided line and line at pin hole place, to produce friction, the demand of extensively carrying out to meet growing undergoing laparoscopic surgery of children.

Summary of the invention

In order to make up the deficiencies in the prior art, this utility model provides a kind of Kirschner wire, for laparoscopic repair of pediatric indirect inguinal hernia or vaginal process patent.

This utility model is achieved by the following technical solution:

A Kirschner wire, it comprises needle body, and described needle body is provided with the needle tip being connected as a single entity, and needle tip is provided with the first pin hole and the second pin hole that stringer is arranged, and described needle tip is flat shuttle shape.

The cross section of described needle tip is arcuation.

The beneficial effects of the utility model: needle tip is flat shuttle shape, sharply and not sharp, just can ligation hernical sac or vaginal process outside peritoneum, and be Complete Ligation, do not stay gap, less to tissue injury, needle tip is provided with the first pin hole and the second pin hole, has avoided line and line at pin hole place, to produce friction, and in peritoneoscope ligation operation process, convenient and practical and economy is easy to get, the side of needle tip is arcuation, is convenient to the operation that dissociates at peritoneum place.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the partial enlarged drawing at A place in this utility model Fig. 1;

Fig. 3 is side view of the present utility model;

In figure, 1 is needle body, and 2 is needle tip, and 3 is the first pin hole, and 4 is the second pin hole.

The specific embodiment

Below in conjunction with accompanying drawing, this utility model is further described:

This utility model device comprises needle body 1, and described needle body 1 is provided with the needle tip 2 being connected as a single entity, and needle tip 2 is provided with the first pin hole 3 and the second pin hole 4 that stringer is arranged.

During use, the first pin hole 3 is passed in its fold position after the doubling of 2-0 not damaged line, the fold position of the 2-0 not damaged line through hole is drawn to one section to backshank, be about 10cm, the second pin hole 4 is through 4# monofilament lines, and the 4# monofilament lines line tail at two ends grips to prevent that with mosquito pincers silk thread from coming off.The Kirschner wire of putting on line is thrust to the through external lamina of peritoneum of the outside upper side of collar extension in stomach wall by skin, needle tip 2 is moved under water outward at peritoneum, first with the free inner side of pin half-turn, push spermatic cord blood vessel and deferent duct open, below interior collar extension, puncture peritoneum and penetrate abdominal cavity, under peritoneoscope, use nipper that the fold position of 2-0 not damaged line is pulled out from the first pin hole 3, and 2-0 not damaged line is fitted tightly treating on ligation hernical sac neck or vaginal process wall, with intraperitoneal nipper, the fold position of the 2-0 not damaged line of pulling out is clamped, and outwards pull out pin, take out two end line tails of tight 4# monofilament lines simultaneously, Kirschner wire is withdrawn into needle tip 2 and is positioned at the outer first inserting needle of peritoneum position, in this process because the length of 2-0 not damaged line is enough, its not broken line tail stay outside peritoneum always, then half-turn outside collar extension in a Kirschner wire with 4# monofilament lines being dissociated, at the former puncture of peritoneum place, go out pin and enter abdominal cavity, the fold position of 2-0 not damaged line is drawn between the two end line tails and pin of 4# monofilament lines, connecting pin exits in the lump with 4# monofilament lines, the fold position of 2-0 not damaged line is taken out of to stomach wall entry point, 2-0 not damaged line fold position is cut off, now 2-0 not damaged line has been looped around and has treated ligation hernical sac neck or vaginal process place, high ligation hernical sac neck or vaginal process, form two-wire cerclage, toe-in is beaten outside peritoneum.
