Automatic device for calcaneal fracture reduction and use method thereof

Abstract

The invention provides an automatic device for calcaneus fracture reduction and a using method thereof. The device comprises a traction mechanism fixedly connected with a cuneiform bone and used for driving the cuneiform bone to be pulled forwards, and a calcaneus extrusion mechanism fixedly connected with a calcaneus and used for transversely compressing the calcaneus. The calcaneus extrusion mechanism is connected with a bottom supporting structure and a prying mechanism located above the instep of the human body; the controlled ends of the traction mechanism, the calcaneus extrusion mechanism and the prying and shifting mechanism are respectively connected to the output end of the controller. According to the device, manual precise reduction action is replaced, stretching traction, extrusion and prying reduction of the calcaneus can be precisely and quantitatively carried out, the operation time is shortened, precise reduction of the calcaneus is achieved, the radioscopy frequency is reduced, remote control can be carried out while CT scanning is carried out in the operation, and the operation efficiency is improved. Therefore, a doctor can control resetting at a safe position without rays, and a patient and medical staff are protected to a great extent.

Description

technical field [0001] The invention relates to the technical field of orthopedic medical devices, in particular to an automatic device for calcaneus fracture reduction and its application method. Background technique [0002] The calcaneus, the largest tarsal bone in the foot, is an irregular rectangular structure composed of a thin layer of cortical bone surrounded by rich cancellous bone. Calcaneal fracture is the most common fracture in the foot tarsus. Calcaneal fracture is characterized by severe pain in the heel, obvious swelling and ecchymosis, inability to walk on the heel, and calcaneal tenderness as the main manifestations. The disease occurs more frequently in adults, and is often injured by falling or squeezing from a high place. Often accompanied by vertebral fractures, pelvic fractures, head, chest, and abdominal injuries. The calcaneus is a cancellous bone with abundant blood supply, and nonunions are rare. However, if the fracture line enters the articula...

AI Technical Summary

Problems solved by technology

[0008] The present invention proposes an automatic device for calcaneus fracture reduction and its use method, in order to solve the problem of time-consuming and labor-intensive operation in the traditional calcaneus fracture reduction method, and the radiation influence on medical staff and patients due to the high frequency of radiation radiation , to reduce the number of fluoroscopy in the operation, and at the same time replace the manual precise reset action, laying the foundation for the remote operation of the operation without surgery in the future
