Phalanx fixation sight

Abstract

The invention discloses a phalange reset fixation sight, comprising: a finger rest and a base, a support rod is fixed on the base, the finger rest is arranged on the top of the support rod; the end surface of the finger rest is U-shaped, and the A needle inlet is provided on the inner wall of the finger rest, and an aiming hole is opened on the side wall of the finger rest, and the needle inlet communicates with the aiming hole. Through the above method, the present invention can solve the problems of temporary fixation of the fractured end of the phalanx and difficult insertion of the Kirschner wire during the operation.

Description

technical field [0001] The invention relates to the field of phalange fixation devices, in particular to a phalange reduction and fixation collimator. Background technique [0002] Phalangeal fracture is a very common injury in patients with hand trauma. Open reduction and internal fixation with Kirschner wires is a relatively traditional treatment method. The operation method is simple, the intraoperative injury is small, and the postoperative fixation is relatively firm, so its clinical effect is definite. [0003] The problems often encountered in Kirschner wire internal fixation of phalanx fractures are: 1. There is no professional instrument for temporary fixation after the fractured phalanx is reset. Reset; 2. The insertion point of the Kirschner wire on the phalanx is easy to slide and difficult to control. Sometimes it is necessary to select different insertion points to insert the needle repeatedly, which increases the damage to the operation area; 3. Because the ph...

Problems solved by technology

[0003] The problems often encountered in Kirschner wire internal fixation of phalanx fractures are: 1. There is no professional instrument for temporary fixation after the fractured phalanx is reset. Reset; 2. The insertion point of the Kirschner wire on the phalanx is easy to slide and difficult to control. Sometimes it is necessary to select different insertion points to insert the needle repeatedly, which increases the damage to the operation area; 3. Because the phalange is thin, it is easy to insert the needle. Changing the direction makes it difficult to adjust the angle of needle insertion, which makes the fixation effect unsatisfactory. Sometimes it is necessary to exit and re-select the angle of needle insertion
