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

Abstract

The invention discloses a phalanx reset fixation sighting device. The phalanx reset fixation sighting device comprises a finger support and a base, wherein the base is fixedly provided with a supporting rod, and the finger support is arranged at the top end of the supporting rod; the end surface of the finger support is in a U shape, a needle inlet is formed in the inner wall of the finger support, a sighting hole is formed in the side wall of the finger support, and the needle inlet is communicated with the sighting hole. In such a way, according to the phalanx reset fixation sighting device disclosed by the invention, the temporary fixation of a phalanx fracture end during an operation and the problem that a Kirschner needle is difficult to enter can be solved.

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...
