Kirschner wire provided with ring

Abstract

The invention belongs to an instrument of the department of orthopaedics, and provides a kirschner wire provided with a ring, which can be used for multiple fracture treatment. A wire body section of the kirschner wire (1) is sleeved with the ring (2) which can freely rotate along a longitudinal axis of a wire body; two bosses (3 and 4) or a groove are / is formed in the wire body section for limiting vertical movement of the ring (2); and the ring (2) can adopt a round shape, a flat round shape, a laced shape, an irregular ring shape or a distortion shape; the boss on the point side of the kirschner wire can adopt a section of thread (4); the boss on the tail side of the kirschner wire can adopt a section of polygon body (3); a ring-shaped preliminary broken incisure (5) is arranged in the junction position of the tail section of the kirschner wire and the boss (3) on the tail side of the kirschner wire; and the kirschner wire, the ring and a tension band material can adopt metal or polymer materials, and overall package and disinfection are performed for standby application. The kirschner wire and the tension band material are connected into a whole through the ring, so that the sliding of kirschner wire in a bone is limited, the structure is simple, the surgical operation is convenient, and the fixation is reliable.

Description

technical field [0001] The invention belongs to an orthopedic medical device, in particular to a Kirschner wire with a ring that can be used for treating multiple fractures. technical background [0002] At present, orthopedic surgeons often use Kirschner wires to treat patella, olecranon, greater trochanter and other bone end avulsion fractures. It is easy to operate, economical and practical, but the Kirschner wires will slide, wander and be inconvenient to bend during use. , The steel wire is not close to the bone end and slips, the Kirschner wire is not compatible with the steel wire, and the problems such as inability to move early after the operation have brought a lot of troubles to both doctors and patients, causing unnecessary disputes, so the use of ordinary Kirschner wires has gradually decreased. People have made a lot of improvements to it, and there have been a variety of perforated Kirschner wires, such as "A Tension Steel Wire Internal Fixation System for Fra...

AI Technical Summary

Problems solved by technology

[0002]At present, orthopedic surgeons often use Kirschner wire to treat patella, olecranon, greater trochanter of femur and other bone end avulsion fractures. It is easy to operate, economical and practical. However, problems such as Kirschner wire sliding and wandering during use, inconvenient bending, steel wire not being close to the bone end and slipping, Kirschner wire not matching the steel wire, and inability to move early after surgery may occur, which bring a lot of trouble to both doctors and patients, resulting in Unnecessary disputes, so the use of ordinary Kirschner wires gradually decreased

People have made a lot of improvements to it, and there have been a variety of perforated Kirschner wires, such as "A Tension Steel Wire Internal Fixation System for Fracture Treatment" (Patent No. 200810004381.5) published on July 29, 2009. The problem of Kirschner wire sliding, but drilling on the Kirschner wire body, on the one hand, reduces the strength of the Kirschner wire, and on the other hand, when the tension band material is penetrated into the drilling operation for fracture fixation, the tension band material will It is inconvenient to use as the Kirschner wire rotates
