Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings, so that the public can better grasp the specific implementation means of the present invention and fully understand the advantages and effects of the present invention. However, the present invention is not limited by the embodiments.

[0029] Referring to Fig. 1, human orthopedic surgery navigation system according to the present invention takes computer 1 with display and input terminal as core, and on the input / output port of computer 1, establishes a CT tomography scanner 2, a C-arm X-ray respectively Machine 3 and a space servo positioning controller 4A or 4B. Wherein, the space servo positioning controller 4A or 4B is arranged between the transmitting source and the receiving head of the C-arm X-ray machine 3 . Except the space servo positioning controller 4A or 4B, the terminal equipment adopted by the system of the present invention is all known equipme...

Abstract

The present invention discloses one kind of human body orthopedic navigation system. The system has one computer with display and input terminal as the core, one CT or MR tomographic scanner connected to the I/O port of the computer, one C-arm or G-arm X ray unit, and one spatial servo location controller. The 2D images taken with the C-arm or G-arm X ray unit is first used in establishing virtual stereo operation scene, the 3D bone model established with CT or MR tomographic scanner before operation is then set into the established virtual stereo scene for registration to obtain position mapping relation between the 3D bone model and the 2D images, and the spatial servo location controller is finally computer controlled for orthopedic navigation. The system of the present invention has saving in apparatus investment and no strict requirement in the electromagnetic interference resisting capacity of the operation room.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a stereotaxic positioning and navigation system for orthopedic surgery. Background technique [0002] Computer-aided surgical navigation is a new technology that is emerging. It is based on medical imaging, and with the assistance of high-performance computers and professional software, it realizes the visualization of minimally invasive surgery by tracking and positioning surgical instruments, thereby greatly Improve the success rate of surgery and reduce the occurrence of surgical complications. [0003] The current orthopedic surgery navigation systems are mainly divided into two categories: [0004] One type is guided by a C-arm X-ray machine, and the image data of the operation area is obtained through an isocentric C-arm X-ray fluoroscopy machine, and the image data set is transmitted to the image-guided workstation, which designs and displays the pedicle screws to be placed The t...
