Digital skeleton operation repair method and system

Abstract

The invention relates to a digital skeleton operation repair method and system. The digital skeleton operation repair method includes the steps of carrying out CT scanning to affected portions of orthopedic patients to obtain corresponding image data, performing three-dimension reconstruction and resetting according to the image data of patients, carrying out design of implants, position determination of screw holes, type selection of screws and the like under guidance of model parameters, finally, printing simulated models (including operation assistant stents) of the affected portions of the patients by the 3D printing technology, carrying out a series of pre-operative simulation processes, such as repairing, positioning and fixing to the simulation models; thereby, increasing operability and precision of skeleton operation, reducing operative risk, and providing a new practice method for customization of patients.

Description

technical field [0001] The invention belongs to the field of orthopedic surgery and relates to three-dimensional reconstruction of CT data, surgical guide plate design, virtual assembly of implants, 3D printing of disease body models, auxiliary preoperative planning, and surgical simulation. technical background [0002] At present, the traditional bone repair surgery process is that doctors use the CT image data of the diseased part taken by the patient to judge the shape, size, surrounding tissue and damage of the bone based on experience, and formulate a surgical plan for the patient. Since there is no precise model guidance for this process, it completely depends on the subjective judgment of the doctor. Especially for orthopedic operations with high difficulty and complex organizational structure, only relying on the doctor's experience will often bring fatal danger, and it is easy to damage the nerves, blood vessels, and surrounding areas of the diseased body. importan...

Problems solved by technology

Since there is no precise model guidance for this process, it completely depends on the subjective judgment of the doctor. Especially for orthopedic operations with high difficulty and complex organizational structure, only relying on the doctor's experience will often bring fatal danger, and it is easy to damage the nerves, blood vessels, and surrounding areas of the diseased body. important organs, increasing the risk of surgery

[0003] The design of implants and surgical auxiliary guides in traditional bone repair surgery is mainly carried out with the help of third-party engineering software. The design process is more complicated, and it cannot be organically combined with the patient's CT data, resulting in insufficient accuracy of the designed model. slow postoperative recovery
