Bone registration method, bone registration system, bone registration control device and trackable element

Abstract

The invention provides a bone registration method, a bone registration system, a bone registration control device and a trackable element. The bone registration method comprises the following steps of: acquiring mark point information obtained by performing corresponding operation on a bone surface through the tail end of the trackable element; acquiring bone image data obtained by scanning the bone surface by a scanning device of the trackable element; and performing virtual reconstruction on the bone surface according to the acquired mark point information and the pre-acquired bone image data. According to the configuration, the virtual reconstruction on the bone surface can be realized by performing corresponding operation on the bone surface via the tail end of the trackable element, preoperative CT scanning is not needed, radiation injury to a patient can be avoided, accurate registration of a physical space coordinate system and an image space coordinate system of the patient isrealized, and the registration work can be completed by only an operator; and moreover, the bone registration method is high in accuracy and convenient to operate, the registration efficiency can be obviously improved, and the operation experience of the operator is excellent.

Description

technical field [0001] The invention relates to the field of robot-assisted surgery systems and methods, in particular to a bone registration method, a bone registration system, a bone registration control device and a trackable component. Background technique [0002] In conventional orthopedic surgery, the surgeon needs to be very familiar with the anatomical structure of the human body, and only rely on the hand and eye system to establish the anatomical structure, which is very dependent on the doctor's experience. Computer Assisted Orthopedics Surgery (CAOS) uses computers to complete the collection and three-dimensional reconstruction of the patient's raw data, and uses the three-dimensional model to guide the doctor's operation, so that the doctor can understand the progress of the operation by observing the images on the computer And guide the operation, even the operation planning can be carried out by the computer, and the operation can be completed automatically o...
