Abstract

The invention provides a calibration method and a calibration system for a surgical operation tool, which uses a non-contact device to obtain the virtual features of the characteristic parts of a surgical operation tool; obtains the coordinates of the tool target in the base coordinate system, and obtains the tool by fitting Target coordinate system; obtain the pose parameters of the virtual feature in the tool target coordinate system to obtain the pose parameters of the feature part in the tool target coordinate system; compare the feature part in the tool target coordinate system An error value between a pose parameter in the target coordinate system and a standard parameter; if the error value is greater than an expected value, it is determined that the surgical operation tool is deformed. Such a configuration eliminates the steps of disinfection, reduces the risk of infection during the operation, and will not affect the operation process. It will not cause additional wear and tear on surgical operation tools, and has good universality, and can adapt to various surgical operation tools of different shapes, while the non-contact equipment itself does not need to 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...
