Positioning system for assisting in spine minimally invasive surgery

Abstract

The invention relates to a positioning system for assisting in spine minimally invasive surgery. The positioning system mainly comprises a degree mechanical arm and a path positioner. The path positioner comprises a flange short locking component, a lifting and sliding component and a double-ring positioning assembly. The mechanical arm can be installed on a trolley; the path positioner is fixed to the tail end of the mechanical arm through the flange short locking component. The lifting and sliding component is connected with the flange short locking component through a clamping and locking body; the double-ring positioning component is connected with a lifting and translation component through a screw. The double-ring positioning assembly is provided with a first positioning ring and a second positioning ring which are used for a guide needle to penetrate through in sequence to position the guide needle, and the first positioning ring and the second positioning ring are separated with each other and concentrically arranged; the lifting and sliding component can drive the double-ring positioning component to conduct translation motion in the axial direction of two rings. The positioning system for assisting in the spine minimally invasive surgery can assist a doctor in accurately positioning the transplanting path of the spine minimally invasive surgery under the condition that the radiation frequency is few.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a positioning system for auxiliary spinal minimally invasive surgery. Background technique [0002] Minimally invasive spinal surgery requires less traction and stripping of soft tissues, which can reduce postoperative pain and shorten recovery time; and minimally invasive spinal surgery performs limited resection of bony structures, thereby reducing the possibility of postoperative spinal instability. Therefore, minimally invasive spinal surgery techniques have developed rapidly in the past decade. Minimally invasive spinal surgery mainly includes microscopic discectomy under minimally invasive access, minimally invasive lumbar hemilaminectomy, transforaminal lumbar interbody fusion, lateral lumbar interbody fusion, and minimally invasive posterior approach fixed technology. Compared with traditional open surgery, due to the need for minimally invasive tunnel positioning under fluorosc...

AI Technical Summary

Problems solved by technology

Due to the complexity of the anatomical structure of the spine and the limitations of the doctor's means of observing the spine, the operation is very difficult; the drilling accuracy of the spine is not high, and the drilling operation deviates from the set path; in addition, the repeated use of X-ray fluoroscopy makes doctors, Patients and related personnel are exposed to radiation for a long time
