Knee joint replacement method and device of laser osteotomy surgical robot

Abstract

The invention relates to the field of artificial intelligence, and discloses a knee joint replacement method of a laser osteotomy surgical robot, which comprises the following steps: performing image enhancement on an initial imaging image of a knee joint of a user to obtain an enhanced image; a segmented area in the enhanced image is detected through an area detection model trained in a laser osteotomy surgical robot in advance, a laser osteotomy device is used for cutting the knee joint of the user, a cut knee joint is obtained, and a cut image of the cut knee joint is collected; identifying a joint replacement area of the cut image by using a target object detection model trained in advance in a laser osteotomy surgical robot, and performing osteotomy on the cut knee joint by using a laser osteotomy device to obtain an osteotomy knee joint; a joint replacement point of the osteotomy knee joint is positioned using a positioning device in the laser osteotomy surgical robot to install a joint prosthesis of the user's knee joint using a replacement device. The knee joint replacement operation can be intelligently achieved, and meanwhile the risk of the knee joint replacement operation can be reduced.

Description

technical field [0001] The present invention relates to the field of artificial intelligence, in particular to a knee joint replacement method, device, electronic equipment and computer-readable storage medium of a laser osteotomy robot. Background technique [0002] The knee joint is an important weight-bearing joint of the lower limbs. Its structure and function are the most complex among human joints. At present, knee joint replacement surgery is usually based on professional doctors removing the hyperosteogeny and synovium in the joint and placing it in front of the tibia. Extramedullary positioning rod and osteotomy module, after fixation, perform tibial osteotomy according to the setting of the osteotomy module, then drill a hole on the femur and insert the intramedullary positioning rod, install and fix the osteotomy module to perform distal femoral The joint prosthesis installation of the subsequent knee joint is realized after the osteotomy of the distal end.

Problems solved by technology

However, this requires repeated and precise positioning of the osteotomy position, which makes the process more cumbersome and consumes a lot of manpower and energy.

[0003] In addition, the mechanical osteotomy tool currently used in knee replacement surgery is an oscillating saw that cannot achieve precise bone cutting. When cutting dense hardened bone, the saw blade will be repeatedly ground, which will have adverse effects on flat surface cutting; followed by Osteotomy will inevitably produce shaking perpendicular to the osteotomy plane, and the surface of the osteotomy will be uneven, which may increase the risk of failure of the joint prosthesis; at the same time, excessive heat will be generated when the pendulum saw repeatedly grinds and cuts hardened bone , lead to thermal necrosis of the bone surface; when the mechanical saw cuts the bone tissue, it will also cause mechanical damage to the bone, destroy the microstructure of the bone tissue, and produce a large amount of bone debris. Since these bone debris are sequestrum, they will cause Aseptic necrosis increases the time for macrophages to clean the wound, prolongs the healing time of the bone-prosthesis interface, and thus hinders bone regeneration

All of these phenomena increase the risk of knee replacement surgery failure
