Embodiment Construction

[0018] The following will focus on the application of the patent of the present invention in individualized navigation template-assisted orthopedic surgery. For complex spinal operations such as skull base depression, scoliosis, and lumbar disc herniation in spinal surgery, it is difficult to complete the entire operation accurately if only relying on the doctor's surgical experience, and the postoperative effect is often not ideal, which also makes Corresponding knowledge of spine surgery is difficult to popularize. With the popularization of advanced medical imaging technology and the emergence of computer-aided navigation equipment, the development of spine and joint surgery has been promoted. Due to the high price of computer navigation equipment, it is difficult to popularize it on a large scale. Then, based on 3D printing technology and reverse engineering technology, individualized navigation template assisted orthopedic surgery appeared. Compared with computer navigat...

Abstract

The invention relates to a method for designing an assistant positioning sleeve of a personalized navigation template. The method mainly includes: acquiring data of a lesion location according to advanced medical image CT/MRI, and combining with reverse engineering and digital medicine to complete designing of the personalized navigation template; on this basis, according to length and inner diameter of a navigation template positioning pipeline, completing designing of the assistant positioning sleeve and an assistant supporting handle in AutoCAD software; after designing of the sleeve and an assistant supporting structure is completed, adopting a titanium alloy material, and utilizing conventional cutting or 3D printing technology to process the assistant positioning sleeve. CT/MRI data and reverse engineering technology are utilized to complete accurate designing of the navigation template; on the basis of the navigation template, the assistant positioning sleeve of the navigation template is specially designed in order to avoid breakage, wearing and sliding after being positioned of the navigation tube and postoperative infection caused by a navigation tube in the process when the navigation template is used to assist the operation process, and accurate clamping is realized by utilizing a sawtooth-shaped structure at the end of the positioning sleeve; the sleeve is made by combining the titanium alloy material, so that postoperative infection caused by the fact that bits generated by wearing of the navigation template are left in the body of a patient in the process of operation is avoided, and accurate positioning in the process of operation is realized.

Description

technical field [0001] The patent of the present invention is aimed at the positioning difficulties existing in the use of the individualized positioning and navigation templates used in the cervical spine, spine, lumbar spine and joints. The positioning tube is worn and ruptured, resulting in sudden injury during orthopedic surgery, and corresponding postoperative problems. infection. In order to improve the above situation, a set of personalized navigation template auxiliary positioning sleeve is specially designed to assist orthopedic surgery, avoid accidental surgical accidents and improve surgical positioning accuracy. Background technique [0002] In spinal surgery and other related orthopedic operations, pedicle screw internal fixation is a relatively stable spinal fixation method, and it is a relatively mature operation method commonly used in many hospitals. It can be seen from the anatomical structure that the anatomical structure of the pedicle of the human body ...
