Embodiment Construction

[0031] In order to make it easier for those skilled in the art to understand the present invention, the specific implementation manners of the present invention will be described below with reference to the accompanying drawings.

[0032] Such as figure 1 As shown in ~, a closed reduction device for comminuted calcaneal fractures includes a calcaneal fixation component 1, a calcaneal airbag extrusion component 2, and a calcaneal traction component 3; the calcaneal fixation component 1 is used to fix the anterior bone of the calcaneus The talus can limit the position of the calcaneus airbag extrusion assembly 2 at the same time. The calcaneus airbag extrusion assembly 2 squeezes and holds up the fracture site of the calcaneus from both sides and the bottom of the calcaneus. The calcaneus traction assembly 3 pulls the raised end of the calcaneus Move down to the original position.

[0033] The calcaneus fixation assembly 1 includes a plate 11 and a plate 2 12, the plate 11 and ...

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a closed reduction device for comminuted calcaneus fracture, which comprises a calcaneus fixing assembly, a calcaneus air bag extrusion assembly and a calcaneus traction assembly. The calcaneus fixing assembly is used for fixing the anterior bone and the talus of the calcaneus and can limit the calcaneus air bag extrusion assembly, the calcaneus air bag extrusion assembly extrudes and supports the fracture part of the calcaneus from the two sides and the bottom of the calcaneus, and the calcaneus traction assembly pulls the tilted end of the calcaneus to move downwards to the original position. According to the device, comminuted calcaneus fracture can be reduced without an external surgical incision, and then the calcaneus is percutaneously fixed by a kirschner wire, bone cement or a locking steel plate. Therefore, intraoperative bleeding and complications related to surgical incisions are reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a closed reduction device for comminuted calcaneal fractures. Background technique [0002] Due to the collapse of the articular surface and the change in the shape of the calcaneus, comminuted calcaneus fractures will lead to traumatic arthritis if the calcaneus shape is not restored by surgery. Calcaneal joint fusion surgery. [0003] In X-ray examination: Lateral films can clearly show the Bohler angle and Gissane angle, which reflect the degree of fracture compression; the normal Bohler angle ranges from 25° to 40°, and once the Bohler angle is less than 15°, it is considered serious injury ; The Gissane angle is a very important anatomical landmark, which is formed by the extension of the anteroposterior articular surface of the calcaneus and the outer surface of the calcaneus body. It has a good indication for the reduction of the fracture. sex sign. ...
