Document Type and Number:
WIPO Patent Application WO/2023/216466
Kind Code:
A1
Abstract:
An end tool error detection method and device for an orthopedic surgical robot. The method comprises: acquiring a theoretical coordinate model of an assembly and theoretical coordinates of a reference point at the front end of a surgical tool, wherein the assembly comprises an end gripper (220) and a surgical tool of an orthopedic surgical robot fixed on a measuring base; measuring the assembly by means of a three-coordinate instrument, establishing a measurement coordinate system for the end gripper (220) in the theoretical coordinate model on the basis of the measurement result, and determining measurement coordinates of the reference point in the measurement coordinate system; and determining a spatial error value of the reference point on the basis of the determined measurement coordinates of the reference point and the theoretical coordinates of the reference point. Assembly accuracy can be verified.
