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: acquiring mark point information obtained by performing corresponding operation on the tail end of the trackable element through the bone surface when a switch of the trackable element meets a corresponding set condition; and performing bone surface virtual reconstruction according to the acquired mark point information in combination with pre-acquired bone image data. Thus, based on the control ofthe switch of the trackable element, the tail end of the trackable element is correspondingly operated on the bone surface, so the virtual reconstruction of the bone surface can be realized; the accurate registration of a physical space coordinate system and an image space coordinate system of a patient is realized; the registration work can be completed by only one operator; the precision is high, and the operation is convenient; the registration efficiency can be significantly improved; and the operation experience of an operator is good.

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...
