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

Embodiment Construction

[0034] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0035] refer to Figure 1 to Figure 5 , an embodiment of the path positioning system for auxiliary spinal minimally invasive surgery of the present invention, including a mechanical arm and a path locator.

[0036] The mechanical arm should have more than six degrees of freedom, and the six-degree-of-freedom series mechanical arm produced by UniversalRobots in Denmark is selected; the mechanical arm can be installed on a trolley.

[0037] The path locator includes a flange short locking assembly, a lifting sliding assembly, and a double-ring positioning assembly. The path locator is fixed at the end of the mechanical arm through a short flange locking component; the lifting sliding component is connected with the short flange locking component by clamping and locking the main body; the double-ring positioning component is connected with the lifting tra...

Abstract

The invention relates to an auxiliary spinal minimally invasive operation positioning system, which mainly includes a mechanical arm and a path locator. The path locator includes a flange short locking component, a lifting sliding component, and a double-ring positioning component. The robotic arm can be mounted on a trolley; the path locator is fixed at the end of the robotic arm with a short flanged locking assembly. The lifting and sliding component is connected with the flange short locking component by clamping and locking the main body; the double-ring positioning component is connected with the lifting and translation component through screws. There are first and second positioning rings on the double-ring positioning assembly for the guide pins to pass through in order to position them. . The system can assist doctors to quickly and accurately locate the implantation path for minimally invasive spinal surgery with less radiation.

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...
