Problems solved by technology

In order to achieve precise positioning of surgical instruments, the length of the marking block needs to be determined in advance, but due to the processing error of the marking block in the production process, the length of each marking block is actually not exactly the same
If there is an error in the length of the measured marker block, it will lead to an error in the positioning of the surgical instrument, so that the effect of the operation cannot be guaranteed

Abstract

The invention provides a length measuring system of a marking block and a surgical robot system.The length measuring system of the marking block comprises a fixing device used for fixing the marking block and enabling the marking block to do circular motion around a provided axis, when the marking block is fixed to the fixing device, the root of the supporting piece is located on the axis, so that the supporting piece drives the center of the marking body to rotate around the axis. The image shooting device is used for tracking the movement process of the marking block so as to record a plurality of three-dimensional space coordinates formed when the center of the marking body moves; the measuring host is used for determining the length of the marking block according to a plurality of three-dimensional space coordinates formed when the center of the marking body moves and a fitting circle center coordinate of the plurality of three-dimensional space coordinates, the length of the marking block is accurately determined, and therefore the operation effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical robots, in particular to a method and device for measuring the length of a marking block, electronic equipment, and a surgical robot system. Background technique [0002] Robots and other automation equipment have been widely used in the industrial field, showing obvious advantages in terms of operational flexibility, stability and accuracy. In order to solve the problems of insufficient precision, excessive radiation, large incisions, and operator fatigue in surgical operations, people began to discuss how to introduce robotic methods into surgical operations. treatment methods and systems. [0003] In order to support the completion of high-quality surgery, marker blocks (also called markers) are used for positioning of surgical instruments. In order to realize the precise positioning of the surgical instrument, the length of the marking blocks needs to be determined in advance, however, due t...
