Problems solved by technology
[0003] However, most robot navigation needs to collect three-dimensional data during the operation, which increases the radiation during the operation. In addition, most robot navigation systems need to install a reference frame on the patient and use a binocular camera, which is complicated to operate; a single CT navigation mode It does not provide access information for surgery; C-arm machine-assisted navigation only provides two-dimensional images, and multiple X-ray images need to be taken during the operation, and patients and medical staff receive a large amount of radiation; electromagnetic navigation combines two-dimensional images or three-dimensional images , to provide doctors with the real-time position information of the guide needle in the human body, and the accurate needle insertion direction needs to be found by the doctor himself

The invention provides a surgical navigation positioning system and device and a storage medium, a computer instruction is stored on the readable storage medium, and when the computer instruction is executed by a processor, the method comprises the following steps: acquiring a plurality of X-ray images including a calibration plate and a patient focus, determining a three-dimensional needle insertion channel based on the X-ray images, and determining the three-dimensional needle insertion channel according to the three-dimensional needle insertion channel; the operation path, the target position and the target posture of the mechanical arm are determined on the basis of the three-dimensional needle inserting channel, the mechanical arm is controlled to operate to the target position according to the operation path and keep the target posture on the basis of the operation path, the target position and the target posture of the mechanical arm, and a doctor can be helped to conduct precise screw placement; meanwhile, doctors and patients can receive minimum X-ray radiation, and the complexity and the use difficulty of the navigation system are reduced.
Description
technical field [0001] The invention relates to the field of orthopedic medical instruments, in particular to a surgical navigation and positioning system, a device and a storage medium. Background technique [0002] In recent years, orthopedic surgery has made great progress, and has gradually entered the stage of precise and minimally invasive surgery. Taking spine surgery as an example, the anatomical structure of the spine is complex and adjacent to important blood vessels and nerves. In spine surgery, pedicle screws need to be accurately placed. However, due to the different conditions of patients, the surgical plans are also different, so accurate The operation of screw placement has become the key and technical difficulty of these operations. In order to improve the accuracy of screw placement in orthopaedic surgery, reduce the damage of nerves and organs and blood vessels, and improve the success rate of surgery, various orthopaedic navigation systems have been devel...
