Abstract

The present invention provides a readable storage medium, a bone modeling registration system, and an orthopedic surgery system, wherein a program is stored on the readable storage medium, and when the program is executed, the following is achieved: acquiring bone surface data of a predetermined object, the The bone surface data is obtained through a depth sensor connected to a predetermined object; three-dimensional reconstruction is performed according to the bone surface data to obtain a first virtual model; the first virtual model is registered with a preset second virtual model to obtain A first coordinate transformation relationship between the depth sensor coordinate system and the navigation image coordinate system; based on the first coordinate transformation relationship, using the real-time bone surface data feedback obtained by the depth sensor to obtain the navigation image coordinates of the predetermined object The real-time coordinates under the system. Such a configuration realizes the registration of the preoperative image model and the actual bone model during the operation. During the whole registration process, no drilling is required, no additional trauma is required, and the possibility of infection is reduced.

Description

technical field [0001] The invention relates to the field of robot-assisted surgery systems, in particular to a readable storage medium, a bone modeling registration system and an orthopedic surgery system. Background technique [0002] In recent years, surgical navigation systems have been increasingly used in surgical operations, especially in orthopedic operations. For example, MAKO orthopedic surgery navigation system and Robodoc orthopedic surgery navigation system, etc., use the combination of robotic arm and infrared optical navigation equipment, according to the doctor's preoperative planning, combined with the intraoperative registration and registration technology, use robots to assist doctors to complete surgical operations . Among them, the bone registration registration technology is to obtain the coordinate transformation relationship between the virtual bone model of the navigation system and the actual bone, but the current general registration tools and met...
