Embodiment Construction

[0030] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] like Figure 1-2 As shown, the present invention includes a clamping device, a head inclination adjustment device for adjusting the head inclination angle, an inclination adjustment device symmetrically arranged at both ends of the head inclination adjustment device for adjusting the inclination angle, and an inclination adjustment device for adjusting the head inclination angle. The displacement adjustment device for the displacement of the inclination device and the probe guide cylinder 15 for installing the probe; through determining the displacement, inclination angle and head inclination angle, the precise positioning of the space point can be achieved, so as to realize the precise drilling of the "target" part The purpose is to reduce the deviation and surgical risk caused by relying on the doctor's experience and judgme...

Abstract

The invention provides a spatial positioning auxiliary drilling device, which includes a clamping device, a head inclination adjustment device for adjusting the head inclination angle, and an inclination adjustment device symmetrically arranged at both ends of the head inclination adjustment device for adjusting the inclination angle device, a displacement adjusting device for adjusting the displacement of the head inclination device, and a probe guide cylinder for installing the probe; the present invention can accurately locate the needle entry point and orientation of the pedicle screw of the spine, and has a simple structure. It is convenient to use, low in cost and suitable for popularization in hospitals at all levels.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a space positioning auxiliary drilling device. Background technique [0002] At present, for the positioning of the surgical pedicle of the spine, one is a navigation system based on CT or C-arm cross-sectional scanning and a robotic manipulator-assisted navigation system, and the other is based on experience-based freehand pedicle screw implantation. method. However, the navigation system is expensive on the one hand, it is difficult to promote in hospitals at all levels, and the accuracy of multi-vertebrae navigation is limited. In freehand pedicle screw implantation based on experience, the position of the screw implantation varies greatly from person to person, especially for less experienced operators, the probability of pedicle screw implantation is also greater. Contents of the invention [0003] In order to solve the above problems, the present invention provides a ...
