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; performing region division on the surface of the three-dimensional model according to the first mark points to obtain a plurality of to-be-selected regions; sorting the plurality of to-be-selected areas according to an analytic hierarchy model to obtain a preferred area, wherein the analytic hierarchy model comprises a target layer, a factor layer and a scheme layer, the target layer comprises the plurality of to-be-selected areas, the factor layer comprises a plurality of influence factors of pelvis registration, and the scheme layer comprises a plurality of feasible sorting schemes; selecting at least three second mark points in the preferable area; and registering the primary registration model and the actual pelvis according to the second mark points to obtain a secondary registration model. The pelvis registration method solves the problem of low pelvis registration precision in the prior art.

Description

technical field [0001] The present application relates to the technical field of pelvic registration, 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...
