Abstract

The present invention provides a method and device for detecting error of an end tool of an orthopedic surgical robot. Wherein, the method includes: acquiring a theoretical coordinate model of an assembly and a theoretical coordinate of a reference point at the front end of a surgical tool, wherein the assembly includes an end gripper and a surgical tool of an orthopaedic surgical robot fixed on a measuring stand; Measure the assembly, establish a measurement coordinate system for the end gripper in the theoretical coordinate model based on the measurement results, and determine the measurement coordinates of the reference point in the measurement coordinate system; determine the measurement coordinates based on the determined reference point and the theoretical coordinates of the reference point Spatial error value of the reference point. The present invention can realize the verification of assembly accuracy.

Description

technical field [0001] The present invention relates to the technical field of surgical instruments, in particular to a method and device for detecting error of an end tool of an orthopedic surgical robot. Background technique [0002] In orthopedic surgery, the rasping rod and the end holder of the orthopedic surgical robot are usually assembled into an assembly. Precise filing of the target area. The coordinate accuracy of the reference point of the front end of the end holder and the burr assembly is one of the key factors affecting the accuracy of the system. After assembling the end gripper and the rasping rod of the orthopaedic surgical robot, verify the accuracy of the assembly of the end gripper and the rasping rod, so as to ensure the accuracy of the rasping implementation. Due to the special shape and structure of the assembly formed by the end holder and the filing rod, it is usually difficult to detect errors in the assembly formed by the end holder and the fil...
