Embodiment Construction

[0050] The present invention will be further described below in conjunction with the accompanying drawings.

[0051] Such as figure 1 As shown, the method for editing feature parameters of implants for orthopedic preoperative planning includes the following steps:

[0052] Step 1: Build an implant feature model library, and classify implants according to fracture information and implant feature parameters;

[0053] Step one includes:

[0054] Step 1a: constructing an implant feature model library;

[0055] Based on the feature modeling technology, the surface features and volume features of the implant are sequentially constructed, and the feature parameters are set according to the medical semantics, and then the constructed implant model is added to the implant feature model library;

[0056] Feature modeling technology is one of the key technologies of CAD / CAM integrated system;

[0057] Step 1b: Classify the implant feature parameters;

[0058] The characteristic para...

Abstract

The invention discloses an orthopedics preoperative planning-oriented implant feature parameter editing method. The orthopedics preoperative planning-oriented implant feature parameter editing methodincludes the following steps: a first step, constructing an implant feature model library, and classifying implants according to fracture information and implant feature parameters; a second step, selecting an implant model from the implant feature model library according to three-dimensional morphological parameters and the fracture type of a patient; and a third step: adjusting the feature parameters of the selected implant model to meet the stress requirements of the individual patient. The invention can design an implant meeting the anatomical features and conditions of the individual patient for the individual patient, and is fast and efficient; and the designed implant can match the individual patient well, and a series of postoperative complications such as the restoration loss after fixation, the non-union of the fracture or malunion healing can be reduced.

Description

technical field [0001] The invention relates to a computer-aided preoperative planning technology, in particular to an implant characteristic parameter editing method for orthopedic preoperative planning, and belongs to the technical field of computer-aided design. Background technique [0002] Orthopedic preoperative planning is a key stage in the treatment of bone defects and lesions. Implant selection and design is an important part of orthopedic preoperative planning. Individual patients have significant differences in anatomical structure and behavioral movement, and the displacement of fracture ends and fragmentation of bone fragments are complex and diverse. Although the size or geometric structure of existing implants can meet the diagnosis and treatment needs of most patients, they cannot meet the patients at both ends of the population distribution. Faced with the mismatch between the implant and the bone, orthopedic surgeons often solve it through cold treatment...
