Osteotomy planning method based on visual image, electronic equipment and medium

Abstract

The invention provides an osteotomy planning method based on a visual image, electronic equipment and a medium. The method comprises the following steps: acquiring a pelvis model and feature points reconstructed based on a three-dimensional medical image; selecting a target osteotomy surface in the pelvis model according to the feature points; acquiring at least three selection points on the bone surface of the target osteotomy surface; generating an osteotomy plane according to the at least three selection points; and adjusting the osteotomy plane based on the user operation instruction so as to plan the osteotomy plane at a proper position. According to the method, a doctor can effectively carry out visual osteotomy planning on the reconstructed three-dimensional model. By means of the method, a doctor can find an optimal osteotomy route suitable for subsequent adjustment according to the positions of the pelvis and the blood vessels of a patient before an operation, and a high-risk area with dead crowns can be avoided. According to the method, the uncertainty of the PAO operation can be effectively reduced, the threshold for doctors to implement the operation is reduced, and the controllability in the operation is improved.

Description

technical field [0001] The present application relates to the field of medical image processing, in particular to a method, electronic equipment and media for PAO (congenital dislocation of the hip) surgical osteotomy planning based on visualized images. Background technique [0002] PAO surgery loosens the acetabulum through osteotomy around the acetabulum, then rotates the acetabulum outwards and forwards, changes the direction of the acetabulum, and improves the coverage of the acetabulum on the femoral head, thereby reducing joint wear and delaying or even avoiding long-term joint replacement. Purpose. However, to carry out PAO surgery, one must be aware of the "crown of death". "Death coronary" refers to the thick anastomotic branch between the external iliac artery or the inferior epigastric artery and the obturator artery, also known as the external obturator artery, or the accessory obturator artery, which exists in about 30% of people. Therefore, the "crown of dea...

AI Technical Summary

Problems solved by technology

[0004] The current PAO surgery is difficult to reproduce in the actual operation only based on the doctor's rough planning of the preoperative medical images

Doctors can't intuitively see the effect of osteotomy in the planning process

Moreover, the large number of X-rays required during the operation will result in additional radiation doses

Therefore, this operation is a test of the doctor's experience and on-the-spot adaptability, which limits the application and promotion of PAO surgery.
