Embodiment 1

[0019] Embodiment 1: With reference to the drawings, the present invention is used as an optical-magneto-electricity composite navigation surgical positioning device, which includes surgical instruments, operating tables, computers, machine vision devices connected with computer data, and calibration boards. The surgical instruments 3 are equipped with a magnetic source 4 and marking point 6. The magnetic receiver 2 is installed on the side of the operating table 1. The machine vision device 5 is a set of dual CCD cameras, fixed on the top of the operating table 1, and three magnetic receivers 2 are installed on the side of the operating table 1. The magnetic receivers 2 are also signal-connected to the computer 7 and are installed on the operating table 1 evenly.

Embodiment 2

[0020] Embodiment 2: The overall device is the same as that in Embodiment 1. The machine vision device 5 is a multi-eye stereo vision device, and specifically uses a three-CCD camera, which can further improve the accuracy of navigation and positioning.

Embodiment 3

[0021] Embodiment 3: The overall device is the same as that in Embodiment 1. The machine vision device 5 uses two sets of dual CCD cameras, which are relatively fixedly installed above the operating table 1, so as to further improve the accuracy of navigation and positioning.

Abstract

An electric, magnetic and optical navigations combined locating system for medical operation features that the magnetic source and marking point are arranged on operation tool, at least three magnetic receivers and a group of two CCD cameras, which are electrically connected to a computer, are respectively fixed to and above the operation table for taking the information about the position of operation tool in optical, magnetic and electric coordinate systems and its posture.

Description

Technical field [0001] The invention belongs to the technical field of surgical navigation and positioning, and mainly relates to an optical surgical navigation method and an electromagnetic navigation method, in particular, it is an optical-magneto-electricity composite navigation surgical positioning method. Background technique [0002] In traditional orthopedic surgery, doctors first form three-dimensional imaging and pre-operative surgical planning in their brains based on pre-acquired images of the affected area, and then perform clinical operations. The success of this kind of surgery often depends on the individual surgeon’s clinical experience and skills, it is impossible to quantify the parameters required during the operation, it is prone to positioning deviations, and it is difficult to achieve the best surgical results. [0003] In order to solve the above-mentioned problems in traditional orthopedic surgery, and with the development of computer technology, medical i...
