Retraction type self-limiting decompression orthopedic power surgical equipment for spinal surgery

Abstract

The invention relates to retraction type self-limiting decompression orthopedic power surgical equipment for spinal surgery. The equipment comprises an equipment body, a fixing seat is arranged at the upper end of the equipment body, a connecting mechanism is arranged at the lower end of the equipment body, a separation and retraction device is mounted on the fixing seat, and a guide device is further connected to the fixing seat. An orthopedic power device is connected to the guide device, a connecting plate extends out of the guide device, the separation and retraction device comprises a motor connected with the fixing seat, an electromagnet is arranged on a shaft of a motor and connected with the guide device through the connecting plate, and a leading device is arranged between the connecting plate and the fixing seat. Therefore, a circuit of an electromagnet and operation of the motor are controlled through a travel switch, a cutter bar of the orthopedic power device can rapidly retract and rise instantly when breaking through the inner surface of the bone depending on the outer surface structure of the bone, the cutter bar of the orthopedic power device is prevented from touching important tissues such as nerves, and safety is guaranteed.

Description

technical field [0001] The invention relates to a surgical device, in particular to a retractable self-limiting decompression orthopedic power surgical device for spinal surgery. Background technique [0002] In recent years, the field of spinal surgery has achieved rapid development. Various surgical methods are used for the treatment of different spinal diseases, including open and anterior spinal surgery, posterior surgery, combined anterior and posterior surgery, etc. [0003] Taking intervertebral disc herniation surgery as an example, its treatment will usher in a century-old major change, and the method will also undergo subversive changes: It has been reported in the literature that artificial double-open spinal expansion surgery (CMEL) can widely "induce" the natural absorption of herniated intervertebral discs (RHNP) phenomenon, the absorption ratio can reach 81.3%, and the maximum absorption rate can reach 100%. The mode of "removing" the herniated intervertebral ...

AI Technical Summary

Problems solved by technology

[0005] 1. Manual method: there are problems with large incisions, possible surgical operations, and high risks

[0006] 2. Orthopedic power system: handheld operation, low safety

[0007] 3. Spinal surgery robot: It has been successfully applied clinically, including Israel's Mazor spine assistant robot, South Korea's SPINEBOT spine robot, the United States' Mazor X spine hand T image registration alchemy robot, and my country's Tianji spine surgery robot etc., but they basically use intraoperative X-ray images and preoperative C-style positioning, which can only be used for pedicle screw placement, and the function is very single, which cannot meet the needs of CMEL surgery for bone groove or bone window. decompression requirements
