Abstract

The invention discloses a calcaneal fracture repositor. The calcaneal fracture repositor comprises a boot-shaped block, a front side plate connected to the front side of the boot-shaped block, a skinpull rod connected to the front side plate, a traction device arranged at the bottom of the boot-shaped block, a jacking device rotationally connected to the bottom of the boot-shaped block and a pressurizing device arranged on the boot-shaped block. Traction, opening, squeezing, resetting and fixing operation of the repositor are conducted at the same time, and the repositor can be operated underdirection vision, so that grafted bone, a steel plate and other implants in a surgery are convenient to fix. The calcaneal fracture repositor is scientific and reasonable in structure, good in reseteffect, convenient to use, capable of accurately and individually recovering the calcaneus anatomic form and ensuring that the surgery achieves an ideal effect, saving surgery time, reducing bleedingand radiation and saving labor and suitable for application and popularization in primary hospitals and all major hospitals, and avoids fluoroscopy.

Description

technical field [0001] The invention relates to a medical device, in particular to a resetter for calcaneal fracture. Background technique [0002] Intra-articular calcaneal fracture is a fracture involving the subtalar joint. The fracture of the posterior articular surface is displaced and deformed, and its height, length and width have changed. How to treat the fracture of the calcaneus and restore its height, length and width as well as the BÖhler angle and Gissane angle, reducing the disability rate is one of the difficult problems in trauma orthopedics. Compared with conservative treatment, open reduction and internal fixation can minimize sequelae such as flat feet, heel widening, and persistent pain. During the operation, it is necessary to pry up and reset the collapsed and overturned posterior articular surface, compress and widen the calcaneus body for compression and traction reduction, restore the shape of the calcaneus, and maintain traction for necessary fixat...
