Orthopedic navigation positioning system and method

Abstract

The invention discloses an orthopaedic navigation and positioning system and method, and the system comprises a mechanical arm which is provided with an actuator and a tracer at the tail end; a precision verification device which is used for cooperating with the C-arm machine and the optical tracker to verify and optimize the navigation precision of the system; an optical tracker which is used for collecting the position of the tracer on each device and obtaining the position information of the corresponding device; a C-arm machine which is used for scanning to generate a preoperative 3D image and registering the preoperative 3D image with the intraoperative 2D perspective image; and an upper computer which is used for planning a path according to the preoperative 3D image, controlling the mechanical arm to move to a target position after the preoperative 3D image is registered with the intraoperative 2D perspective image, and carrying out an operation. By means of precise positioning, the operation precision of a person and a mechanical arm can be maximized, wounds of a patient are reduced, meanwhile, the operation process can be accelerated, and radiation borne by doctors and the patient is reduced.

Description

technical field [0001] The invention relates to the field of surgical navigation and positioning, in particular to an orthopedic navigation and positioning system and method. Background technique [0002] At present, spine orthopedic surgery requires doctors to use preoperative and intraoperative medical images to achieve precise positioning of the patient's position in order to perform treatment on the patient's position, such as placing screws or injecting bone cement. The operation is to drill holes at the desired locations. In traditional spinal surgery, the surgeon needs to manually position and maintain the position of the positioning drilling guide tube. This manual process has some disadvantages as follows: [0003] 1. The low accuracy of doctors operating surgical instruments leads to complicated surgical positioning process and low safety; [0004] 2. The doctor's eyes need to constantly switch between the display screen and the patient, which is easy to cause a...

Problems solved by technology

[0003] 1. The low accuracy of doctors operating surgical instruments leads to complicated surgical positioning process and low safety;

[0004] 2. The doctor's eyes need to constantly switch between the display screen and the patient, which is easy to cause accidental injury and complications;

[0005] 3. It is necessary to take X-ray pictures repeatedly for positioning, which increases the operation time and causes unnecessary radiation damage to doctors and patients
