Calcaneus fracture surgery repository

Abstract

Disclosed is a calcaneus fracture surgery repository. The repository comprises a rocker, a transmission mechanism, an alloy frame and a cushion plate, and is characterized in that a rolling shaft is arranged on the rocker, and the rocker is connected with the transmission mechanism; the transmission mechanism further comprises a gear I, a gear II and a transmission plate which are separately driven by gears in a meshed mode; the alloy frame penetrates through the transmission mechanism, and a frame can be opened, and closed and move; the cushion plate is fixed at the utmost top end of the alloy frame, and the cushion plate is a carbon fiber plate and in contact with human body skin. According to the calcaneus fracture surgery repository, the transmission mechanism is used for driving the allow frame to press the cushion plate inwards, and the width of a calcaneus can effectively recover; the carbon fiber cushion plate is used, and therefore the carbon fiber cushion plate is directly in contact with surface skin of foots, and X-ray fluoroscopy during surgery is not influenced. The thickness of the cushion plate is 3 mm, the size of the cushion plate is 30*40 mm, and the pressure intensity brought to the surface of the skin can be dispersed when a bone is pressed.

Description

technical field [0001] The invention relates to medical machinery, in particular to a calcaneus fracture surgical resetter. Background technique [0002] The purpose of calcaneus fracture treatment is to restore the anatomical shape of the calcaneus, that is, restore the length, width, and height of the calcaneus, so that the calcaneal and calcaneocuboid joints can be matched; some scholars have shown that the restoration of the anatomical shape of the calcaneus is directly related to the clinical efficacy . At present, whether it is open plate reduction and internal fixation or percutaneous hollow screw reduction and fixation, the reduction of the width of the calcaneal fracture is a difficult point in surgery. If the normal width cannot be restored, the lateral wall of the calcaneus will remain bulged, resulting in the impact of the lower lateral malleolus with the lateral wall of the calcaneus, displacement or compression of the peroneus longus tendon, and a series of cl...

AI Technical Summary

Problems solved by technology

[0003] For the treatment of the change in the width of the calcaneus, the thumbs of both hands are usually used to press the medial and lateral malleolus and the center of the foot, such as pressing, lateral squeezing, etc., or using external forceps to reset, and these methods have serious defects: manual reduction , although the "surface" pressure is used, the pressure is unbalanced and the pressure is too small; and the external forceps are applied through "points", which is more likely to aggravate the fragmentation of the calcaneus fracture, and it is difficult to meet the requirements of reduction
