Abstract

The invention provides a verification method and verification system for a surgical operation tool. The verification method comprises the following steps of: acquiring virtual characteristics of a characteristic part of the surgical operation tool by using non-contact equipment; acquiring coordinates of a tool target in a base coordinate system, and fitting to obtain a tool target coordinate system; acquiring a pose parameter of the virtual characteristic in the tool target coordinate system to obtain a pose parameter of the characteristic part in the tool target coordinate system; comparing an error value between the pose parameter of the characteristic part in the tool target coordinate system and a standard parameter; and, if the error value is greater than the expected value, determining that the surgical operation tool deforms. Due to the configuration, the disinfection step is omitted; the infection risk in the operation is reduced; the operation process is not influenced; the device is free of extra abrasion to the surgical operation tool, good in universality and capable of adapting to various surgical operation tools of different forms; and the non-contact equipment of thedevice cannot be adjusted.

Description

technical field [0001] The invention relates to the field of robot-assisted surgery systems and methods, in particular to a calibration method and a calibration system for surgical operation tools. Background technique [0002] In artificial joint replacement surgery, it is necessary to use various positioners, guides, etc., for osteotomy before artificial joint installation, so as to ensure the accuracy of osteotomy operation. Different approaches have been proposed to assist surgeons in the positioning of osteotomy guide tools during total knee arthroplasty (TKA) surgery. Generally, in the existing robot-assisted surgery system, an osteotomy guide tool is provided at the end of the robotic arm, and the movement of the osteotomy guide tool is controlled by the robotic arm to realize the positioning of the osteotomy guide tool during knee joint replacement surgery. During the registration of the robotic arm, both the robotic arm system and the positioning system need to obt...
