Volume data visualization method for surgical navigation based on PPC (Panel Personal Computer)

Abstract

The invention relates to the field of medical equipment, and relates to a volume data visualization method for surgical navigation based on a PPC (Panel Personal Computer). A navigation system adopted in the method mainly consists of the PPC, a navigator, an auxiliary infrared position indicator, a reference frame, an adaptor and the like, wherein point-to-point real-time communication can be realized between the PPC and the navigator through a wireless communication technology, and navigation information is transmitted and displayed on the PPC. A main navigation model realized by the method is that the image information of a cross section, a vertical plane and a coronal plane corresponding to a navigation probe point can be displayed on the PPC in real time; furthermore, a section image obtained by intersecting the extending surface of the PPC and the head of a patient is displayed in real time through the PPC. According to the method, standard section images can be displayed, any section image can be displayed through the position of the PPC, tumours and lesions can be auxiliary positioned by doctors, and convenience and help can be brought for surgical operation.

Description

technical field [0001] The invention belongs to the field of medical devices and relates to a volume data visualization method for operation navigation based on a tablet computer. Background technique [0002] The prior art discloses that neuronavigation systems can assist doctors in planning surgical approaches, determining the location and boundaries of lesions, and avoiding damage to surrounding normal tissues and organs. The neuronavigation system has become an indispensable surgical device in the field of neurosurgery; its working principle is to establish an image-guided space based on the patient's own CT, MRI and other imaging data before surgery, and compare it with the real The space where the patient is located is registered; the space locator is used to track the position of the surgical instrument in real time during the operation, and it is converted into the image space, and the virtual surgical instrument is generated and displayed superimposed on the patient...

Problems solved by technology

[0003] The traditional surgical navigation system uses virtual reality technology to superimpose virtual surgical instruments on the patient's image space, and doctors perform surgical operations by observing the navigation screen; this kind of virtual reality technology allows doctors to immerse themselves in the virtual environment created by the computer from the perspective of sensory effects At the same time, in order to observe the position of the surgical instruments relative to the patient during the operation, the doctor has to switch the field of view back and forth between the patient's surgical site and the navigation screen. There is a certain distance, this kind of navigation mode is not conducive to the doctor to concentrate on the surgical site for operation, and at the same time brings errors to the surgical positioning

[0004] In addition, another disadvantage of the traditional surgical navigation system is that it can only display patient images corresponding to the cross-section, sagittal plane, and coronal plane corresponding to the needle tip of the navigation probe, and cannot obtain any cross-sectional image of the patient body data field. When the patient lies on the side and cannot obtain the positive posture, it will have a certain impact on the doctor's judgment

[0006] At present, the medical navigation equipment based on mobile display related to the present invention has: the DASH navigation system developed by BrainLab Company in Germany, which has been used in preliminary clinical trials through CE and FDA certification; but the above-mentioned equipment is expensive and complicated to operate
