Calcaneal fracture manual repositor

Abstract

The invention discloses a calcaneal fracture manual repositor. The repositor comprises two control levers and force sensing components fixed on the control levers, wherein the control levers are in adjustable hinge connection through a chain; each force sensing component comprises a fixed plate, a connecting rod and a force cell; one end of the connecting rod is connected with the fixed plate, and the other end of the connecting rod is connected with the force cell; an outer coating layer which is better compatible with human tissue characteristics is coated outside the fixed plate. According to the calcaneal fracture manual repositor, the principles of hinges and medical sensors are comprehensively utilized, the widened calcaneal transverse diameter can be furthest restored, the mechanical control and qualitative and quantitative description of the operation process can be realized, the device can be safely controlled better, and the traditional Chinese medical method can more standard; moreover, the repositor has the advantages of low treatment cost, relapse prevention, relatively high practicality and the like, and has very high application values in calcaneal fracture conservative treatment and minimally invasive treatment or open reduction and plate screw internal fixation and other perioperative early treatment processes.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a manual reset auxiliary device that can best fit and match the anatomical features of the human heel, and at the same time use the principles of hinges and medical sensors to restore the widened transverse diameter of the calcaneus to the greatest extent. Background technique [0002] Calcaneal fracture is one of the common clinical diseases in orthopedics and traumatology. Falling from heights or car accidents will damage the calcaneus. Under the action of vertical violence, the posterior articular surface interacts with the talus, causing the calcaneus to compress, collapse and shatter. Its main manifestations are widening of the transverse diameter of the calcaneus and changes in the arch of the foot resulting in deformity of the foot, which affects people's walking function. [0003] Clinically, calcaneus fractures need to restore the width of the calcaneus, correct the valgus...

AI Technical Summary

Problems solved by technology

[0005] The use of the manipulative reduction device for calcaneal fractures can well solve the problem of widening of the posterior transverse diameter of the calcaneus. However, with the development of medical technology and the improvement of people's quality of life, people's requirements for medical policies have also increased. Or the use of a simple reset device can no longer meet the medical needs, and there is also a lack of quantitative and qualitative data descriptions, which makes the process of promoting the device encounter many difficulties

At the same time, we also found many problems in clinical application, such as: using the bolt connection method, only the distance between the two operating rods can be adjusted in parallel, and the adjustment flexibility of the operating rods is low; The surface of the calcaneus is designed as a flat surface, which cannot fit well with the inner and outer sides of the calcaneus, which will affect the fixing effect of the device; in addition, when using this device, the relationship between the deformation and pressure of the calcaneus during the extrusion process, the rapid extrusion There is a lack of quantitative and qualitative data to explain the effects of pressure and slow extrusion, whether it will cause secondary fractures, etc., and it is impossible to perform a qualitative and quantitative control of these parameters.
