Spine pedicle screw implanting and locating device

Abstract

The invention relates to the field of medicine, in particular to a spine pedicle screw implanting and locating device. The spine pedicle screw implanting and locating device comprises hardware of a C-shaped arm, an image correction calibration plate, an image collection module, a locating robot, a path locating frame, a position tracking platform, a computer and the like, a spine pedicle screw implanting path planning module and a locating navigation module based on an X ray picture during an operation, wherein the spine pedicle screw implanting path planning module and the locating navigation module are stored in the computer. Through the spine pedicle screw implanting and locating device, according to the anatomical structure characteristics of a spine vertebral body, a coordinate system is established, an operation path planned in a 3D environment before the operation, an operation path planned in a 2D environment during the operation and an operation apparatus path during the operation are expressed, and by the use of the relationship of the three paths, a doctor is guided or a robot is controlled to complete precise operation path locating operation. The spine pedicle screw implanting and locating device can track the position relationships among all objects on a 2D image in real time, reflect the relationship between a tool and pedicle of vertebral arch actually, precisely and timely, eliminate errors of the traditional computer navigation system in an operation process, reduce the operation difficulty, and improve the operation efficacy.

Description

technical field [0001] The invention relates to the medical field, in particular to a spinal pedicle screw implantation positioning device. Background technique [0002] With the development of minimally invasive surgery, pedicle screw internal fixation technology has gradually become a routine operation in spinal surgery. into the vertebral body of the spine. In the traditional pedicle implantation operation, doctors rely on their own professional skills to adjust the surgical path based on the X-ray images taken by the C-arm in the operating room to complete the pedicle implantation operation. Due to the different professional levels of doctors, many operations often have different degrees of sequelae. At the same time, the X-ray image acquisition process will cause radiation damage to doctors and affect their health. Pedicle screw implantation surgery based on computer-aided navigation technology, based on preoperative or intraoperative medical images (CT medical image...

AI Technical Summary

Problems solved by technology

This method is complicated to operate, and the error in the process will be magnified. The positional relationship seen on the navigation image is an illusion, and it cannot accurately and timely reflect the relationship between the tool and the pedicle, and cannot truly detect in real time.
