Embodiment Construction

[0013] see figure 1 , the support rod is composed of a talus support rod 1 and a metatarsal support rod 2, the end of the talus support rod is connected with the metatarsal support rod by a connecting shaft 3, and the talar support rod and the metatarsal support rod are fixed by an adjustment lock rod 4; traction The rod 5 is connected with the shaft of the metatarsal support rod, and the elastic lock 6 is connected between the traction rod and the metatarsal support rod.

[0014] The drawbar is an adjustment lever that is adjusted using the helical ranging principle. The adjustment lock lever is an adjustment lever that uses the principle of helical distance measurement for adjustment. There are scale marks on the housing of the tow bar. There is an annular sheet 8 at the end of the drawbar.

[0015] When in use, the calcaneus end of the traction rod is fixed on the schanz nail 7 of the calcaneus, the talar support rod is fixed on the schanz nail of the talus, and finally ...

Abstract

The invention provides a calcaneus pre-operation returning frame. The calcaneus pre-operation returning frame aims at solving the problem that the returning of the broken calcaneus is difficult when an orthopedist performs operative treatment on the calcaneus. No holding force is performed on the calcaneus in the returning process, so that calcaneus returning operation is difficult, and the risk of faults also occurs. The technical scheme is that a supporting rod is composed of a talus supporting rod and a metatarsus supporting rod, the end of the talus supporting rod is connected with the metatarsus supporting rod through a connecting shaft, the talus supporting rod and the metatarsus supporting rod are fixed through an adjusting lock rod, and a drag rod is connected with a metatarsus supporting rod in a shaft connection mode and is connected with the metatarsus supporting rod through an elastic lock catch. The calcaneus pre-operation returning frame has the advantages that angle adjustment and length adjustment can be performed according to the actual use conditions, fine adjustment can be performed, and infection and the like caused by wound expansion cannot be caused. The calcaneus pre-operation returning frame further has the advantages of being high in control degree, low in cost, stable, reliable and high in practicality.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a calcaneal preoperative reduction frame for preoperative reduction of a fractured calcaneus. Background technique [0002] At present, it is relatively difficult for orthopedic surgeons to reduce the fractured calcaneus in the operation of the calcaneus. There is no holding force on the calcaneus during the reduction process, so that the reduction of the calcaneus can only be performed by experienced doctors, and even then there is a risk of error. When the fracture is complicated, the reduction force is relatively large, which may easily cause damage to the skin around the calcaneus, resulting in tension blisters and even infection. Contents of the invention [0003] The object of the present invention is to provide a calcaneal preoperative reduction frame for preoperative reduction of the fractured calcaneus. [0004] The technical scheme of the present invention is: it comp...
