3D printing navigation system and method for ischial osteotomy in triple osteotomy for hip dislocation

Abstract

The invention belongs to the technical field of surgical auxiliary devices, and discloses a 3D printing navigation system and method for hip joint dislocation triple osteotomy and ischial osteotomy. The hip joint dislocation triple osteotomy ischial osteotomy 3D printing navigation system includes: hip joint Fixation module, image acquisition module, image analysis module, central control module, hip joint model building module, support point determination module, support point positioning module, hip joint support module, osteotomy angle determination module, osteotomy angle adjustment module, osteotomy Navigation module, evaluation module, simulated osteotomy module, and drive module. The present invention realizes the fixation of the hip joint through the hip joint fixation module, reduces the error caused by the movement, and makes the image acquisition and model construction more accurate; the hip joint model construction is carried out through the hip joint model construction module, and the hip joint model is constructed on the hip joint model. Simulate osteotomy, find problems in osteotomy through simulation and correct them in time to improve the accuracy of osteotomy.

Description

technical field [0001] The invention belongs to the technical field of surgical auxiliary devices, and in particular relates to a 3D printing navigation system and method for ischial osteotomy for hip joint dislocation triple osteotomy. Background technique [0002] At present, developmental hip joint dislocation in children is one of the more common congenital lower limb deformities in children, with a high disability rate, which seriously affects the physical and mental health of children, especially hip dislocation in older children. Triple osteotomy is a surgical method that changes the direction of the acetabulum after osteotomy of the ilium, ischium, and pubic bone around the acetabulum, and then changes the acetabulum’s containment of the femoral head. The ischial osteotomy is an important part of it. However, it is difficult to expose the ischia of the hip joint, the surrounding nerves and blood vessels are abundant, and the children’s ischia itself has an angle, whi...

AI Technical Summary

Problems solved by technology

However, it is difficult to expose the ischia of the hip joint, the surrounding nerves and blood vessels are rich, and the children’s ischia itself has an angle, which increases the difficulty of the operation.

In the narrow deformed ischia, the osteotomy must be performed at a strict angle. If the angle is incorrect, the position of the ischial osteotomy will be too high or too low, or the direction will be wrong, which will affect the rotation of the hip joint, affect the surgical effect, and even cause the femoral head Complications such as necrosis and joint stiffness

However, among the current surgical auxiliary devices for triple osteotomy of hip dislocation, there is no device that can achieve osteotomy at a strict angle, which cannot simplify the operation and reduce the risk of surgery.

[0003] Through the above analysis, the existing problems and defects of the existing technology are: currently there is no device that can realize osteotomy at a strict angle in the current surgical auxiliary device for triple osteotomy of hip dislocation, and it is impossible to simplify the operation and reduce the risk of operation. reduce
