Abstract

The invention provides a pelvis registration method, device and system, and the method comprises the steps of registering a three-dimensional model of a pelvis and an actual pelvis according to at least three first mark points, and obtaining a primary registration model, wherein the first mark point is any point of the three-dimensional model; determining a plurality of deviation points according to a primary registration model, wherein the distance between each deviation point and a first reference plane is a first distance, the distance between a corresponding point, in the actual pelvis, of each deviation point and a second reference plane is a second distance, the difference value between the first distance and the second distance is larger than a preset value, the first reference plane and the second reference plane are two corresponding planes, and the predetermined value is greater than or equal to 0; determining a rejecting area according to the plurality of deviation points, wherein the rejecting area is provided with a preset number of deviation points; selecting at least three second mark points in an area outside the rejection area of the primary registration model; and registering the primary registration model and the actual pelvis according to the second mark points to obtain a secondary registration model.

Description

technical field [0001] The present application relates to the technical field of orthopedic revision, and in particular, relates to a pelvic registration method, a pelvic registration device, a computer-readable storage medium, a processor, and a pelvic registration system. Background technique [0002] Although artificial joint replacement is very mature now, due to many reasons such as prosthetic loosening (bacterial / sterile), periprosthetic fractures, prosthetic dislocation, etc., there are still patients after primary joint replacement. A larger fraction required revision surgery. [0003] Due to the many reasons for revision surgery and the complexity of the condition, performing joint revision surgery requires extremely high surgical techniques and rich surgical experience. Even so, the satisfaction rate of revision surgery is still relatively low. Reasonable filling of the defect is an important step in joint revision surgery. With the development of 3D printing te...
