Universal centrum repositor for orthopedic spinal surgery

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a universal centrum repositor for orthopedic spinal surgery, which comprises two supporting seats, the two supporting seats are both provided with sliding cavities, the two sliding cavities are jointly connected with a supporting frame in a sliding manner, one supporting seat is provided with a lifting adjusting mechanism matched with the supporting frame, and the other supporting seat is provided with a locking mechanism matched with the lifting adjusting mechanism. The supporting frame is rotatably connected with a guide lead screw, the guide lead screw is in threaded connection with a fixing seat, the supporting frame is provided with a limiting sliding groove matched with the fixing seat, one end of the guide lead screw is in transmission connection with a servo motor, and the fixing seat is provided with a height adjusting and controlling mechanism. The clamping state of the two clamping plates can be locked in real time, the complexity of manual locking is avoided, and the temperature of the clamping positions of the clamping plates can be adjusted and controlled according to the external temperature change so that the clamping comfort of a patient can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a vertebral body universal reducer used for orthopedic spine surgery. Background technique [0002] With the advancement of medical technology, the operation of reduction and fixation after the entire resection of the diseased vertebral body or deformed vertebral body has been implemented clinically. Between the lower two vertebral bodies, reliable temporary fixation and accurate surgical reduction is an important part of the success of the operation. During the reduction of the vertebral body, two splints on the reducer need to be used to clamp and fix the spine, so as to facilitate the operation. Surgical reduction followed by positioning by implanting the plate. [0003] Nowadays, when the traditional reducer is used to reduce the spine, it is often necessary to manually lock the clamping state of the two splints on the reducer, which is relatively cumbersome.

Problems solved by technology

[0003] Nowadays, when the traditional restorer performs the work of restoring the spine, it is often necessary to manually lock the clamping state of the spine by the two splints on the restorer, which is relatively cumbersome. In addition, the traditional restorer cannot control the temperature of the two splints on it. In the cold winter, the two cold splints directly contact the human body, which will bring discomfort to the patient; and in hot weather, the splint will affect the heat dissipation of the clamping part, making the clamping part sweat easily and bring discomfort to the human body
