Operation positioning device with high precision and positioning method thereof

Abstract

The invention discloses a high-precision operation positioning device and a positioning method thereof, and relates to the technical field of operation positioning devices. The problem that a wire harness is wound and damaged due to follow-up of a driving source is solved. The device comprises a fixed base, the outer wall of the top of the fixed base is rotationally connected with a rotating platform through a rotating drum. The method comprises the steps of starting a lifting motor, adjusting the approximate height of a surgical instrument mounting seat, starting a rotating driving motor, adjusting the approximate angle of the surgical instrument mounting seat and then starting a translation driving motor. Due to the fact that the rotation center of the rotating platform coincides with the axis of the translation driving shaft, translation of the linear moving platform depends on the meshing mode of the straight-cone integrated gear and the bevel gear, the linear moving platform does not interfere with each other when rotating and translating, and the two power sources of the linear moving platform can drive the linear moving platform to rotate and translate. Namely, the rotation driving motor and the translation driving motor are in a static state in the rotation and translation processes, so that the wire harness can be effectively prevented from being wound and damaged.

Description

technical field [0001] The invention relates to the technical field of surgical positioning devices, in particular to a high-precision surgical positioning device and a positioning method thereof. Background technique [0002] In today's medical field, there are many operations that require a considerable degree of accuracy, such as the width, depth, length, angle, etc. of the opening of the surgical site in the affected area. It is very likely that very small errors will affect the success of the operation. , and it is not easy to achieve high-precision and error-free operations only through human feeling and judgment during surgery. This requires surgical positioning devices to fix surgical instruments or instruments and assist positioning. [0003] After retrieval, the Chinese Patent Publication No. CN102342857B discloses a surgical positioning device, including a support frame, a vertical linear drive assembly, a horizontal rotary drive assembly, a vertical rotary drive ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned patent has the following disadvantages: it actually utilizes three sets of linear movement components and two sets of rotary drive components to realize the multi-directional movement of the surgical tool end, but its linear drive components and rotary drive components are relatively independent drive units, and The driving force, whether it is a motor, motor, hydraulic rod, etc., requires the arrangement of wiring harness or oil pipe, and when the rotating component rotates, the driving source of the linear moving component will rotate accordingly, and vice versa, which will cause each drive The wiring harness / oil pipe of the source will be entangled with the components, which is difficult to arrange. Therefore, based on this defect, the present invention only solves how to realize the integrated drive of the linear and rotary drives under the condition that the driving source is relatively fixed, so as to ensure that the connecting parts such as the wire harness / oil pipe are not connected. Wrap breakage occurs for easy layout
