Embodiment Construction

[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0045] See figure 1 As shown, the present invention is a positioning device for robot-assisted anterior cruciate ligament reconstruction surgery, and is a medical device suitable for anterior cruciate ligament reconstruction surgery. C-arm X-ray machine 3, image correction calibration plate 4, image acquisition card 2, positioning robot 6, path positioning frame 7, position tracking platform 5, computer 1, the insertion point of the anterior cruciate ligament and the path position stored in the computer It consists of a planning module, an anterior cruciate ligament insertion and a tunnel positioning navigation module stored in the computer. The image correction positioning plate 4 is installed on the acquisition end of the C-arm X-ray machine 3 with screws 9 (equivalent to installing a disc-type image correction plate and a double-layer on the camera head o...

Abstract

The invention relates to the field of medical science, and particularly relates to an anterior cruciate ligament stopping location and ligament tunnel location device combining with preoperative 3D planning information. The device comprises hardware such as a C-type arm X-ray machine, a gama correction calibration board, an image capturing card, a positioning robot, a path positioning rack, a position trailing platform, and a computer as well as software such as a 3D planning module and a 2D positioning and navigation module which are stored in the computer. The 3D planning module makes use of preoperative 3D image data of knee joints of a patient, assists a doctor in finishing personalized surgical planning, and projecting a 3D environmental message to a 2D navigation message along a specific projection direction. The 2D positioning and navigation module makes use of a 2D medical image in surgical space collected by the hardware as well as location information of various trailing objects and combines the 2D navigation message to construct a navigation environment to control the hardware such as the positioning robot and the path positioning rack to finish an accurate operation path positioning. The anterior cruciate ligament stopping location and ligament tunnel location device can assist the doctor in finishing the precise and personalized operation of anterior cruciate ligament stopping location and ligament tunnel location, thus lowering operative difficulties and enhancing operative treatment efficacy.

Description

technical field [0001] The invention relates to an anterior cruciate ligament insertion point positioning device and a ligament tunnel positioning device incorporating preoperative 3D planning information, in particular to an anterior cruciate ligament insertion point and ligament tunnel positioning device using computer image processing technology and robot technology. Background technique [0002] Anterior cruciate ligament reconstruction surgery is an effective treatment for the indications of ACL rupture. It consists of drilling a hole (ligament tunnel) at the ligament connection points of the femur and tibia of the knee joint, and passing through artificial ligaments or other ligaments. It is fixed in these two ligament tunnels to replace the ruptured ligaments and stabilize the knee joint. One of the surgical difficulties is to correctly locate the insertion point of the anterior cruciate ligament (the connection point of the ligament to the bone) and the position of t...
