Localization punching system and method for joint replacement surgery

Abstract

The invention belongs to the technical field of medical joint replacement, and discloses a positioning punching system and method for joint replacement surgery. The positioning punching system for joint replacement surgery comprises an image acquisition module, a physiological parameter detection module, a central control module, a central point determination module, a joint structure measurementmodule, a punching module and a display module. The center point of joint is determined by the center point determination module in three-dimensional space, and the two-dimensional data obtained by the traditional method, such as X-ray, CT, MRI and other imaging materials and the cadaver specimens are used for locating the center point of joint, and the accuracy is higher. The core stress zone isbetter concentrated to measure and determine the joint center point, and the system better conforms to the measurement of lower limb force lines; meanwhile, the joint structure measurement module is used for for irregular shape joint injuries, and grafted plants and joint injuries can be accurately matched.

Description

technical field [0001] The invention belongs to the technical field of medical joint replacement, and in particular relates to a positioning drilling system and method for joint replacement surgery. Background technique [0002] The connection between bone and bone is called bone connection. Bone connection is divided into direct connection and indirect connection, and joint is a form of indirect connection. Generally, it consists of three parts: articular surface, joint capsule and joint cavity. The articular surface is the contact surface of two or more adjacent bones, one is slightly convex, called the articular head, and the other is slightly concave, called the articular fossa. The articular surface is covered with a layer of smooth cartilage, which can reduce friction during exercise. Cartilage is elastic and can also slow down vibration and impact during exercise. The joint capsule is a kind of tough connective tissue that firmly connects two adjacent bones. The o...

AI Technical Summary

Problems solved by technology

[0004] Traditional joint replacement surgery has a large error in positioning and drilling, and cannot accurately determine the position of the center point; at the same time, for irregular joint injuries, the transplantation matching degree is poor

[0005] The existing positioning and drilling methods for joint replacement surgery have a low degree of intelligence, and the accuracy of the obtained data is poor, resulting in low performance of the equipment
