Preoperative positioning method and system based on three-dimensional vision, medium and computer equipment

Abstract

The invention belongs to the technical field of CT image positioning, and discloses a preoperative positioning method and system based on three-dimensional vision, a medium and computer equipment. A UI interface in the preoperative positioning system based on three-dimensional vision is connected with an industrial personal computer and used for manually controlling the whole system operation and preoperative planning operation; the mechanical arm is connected with the industrial personal computer and used for transmitting and receiving a processing command; the tail end surgical assembly is mounted at a flange at the tail end of the mechanical arm and used for surgical operation; the infrared reflective marking tool is installed at a certain fixed position of the tail end operation assembly and provides a key tracking point. The camera module is mounted at a certain position in the space and is used for tracking the infrared reflective marking tool; the tibia installation tracking tool and the CT machine are connected with the industrial personal computer and used for providing 3D medical images before an operation. In the robot-assisted operation process, a 3D reconstruction algorithm of a CT image is adopted, precise assisted positioning is completed under tracking of a navigation system through a mechanical arm, and the TPA angle precision of the TPLO operation is improved.

Description

technical field [0001] The invention belongs to the technical field of CT image positioning, and in particular relates to a three-dimensional vision-based preoperative positioning method, system, medium, and computer equipment. Background technique [0002] At present, dogs have a special anatomical structure of the knee joint. The tibial plateau of dogs is not flat, but tilted backward. The anterior cruciate ligament is one of the important structures to maintain the stability of the knee joint, which fixes the two bones together. Prevents knee instability when the dog is standing or running. The knee joint is hyperextended when the dog is active, causing injury, slow, degenerative ligament disease, leading to rupture of the anterior cruciate ligament. Generally, it starts with a partial tear and gradually develops into a complete rupture after a period of time. TPLO (Tibial Plateau Leveling Osteotomy, Tibial Plateau Leveling Osteotomy) is a very effective method for the ...

Problems solved by technology

[0003] Through the above analysis, the existing problems and defects of the prior art are: in the prior art, the TPLO operation requires the surgeon to operate according to actual experience, which is prone to artificial surgical errors
