Medical image projection assisted surgical operation system

Abstract

The invention relates to a medical projection assisted surgical operation system which adopts a focus-free miniature laser scanning projection device to project medical image information to the surface of a human body and provides reference for accurate positioning of pathological change positions in a surgical operation. The system mainly comprises a video processing module, a laser source module, a laser driving modulation module, a simulated micro-mirror module and a micro scanning mirror control module, wherein the output end of the video processing module is connected with the input endsof the laser driving modulation module and the micro scanning mirror control module respectively, the output end of the laser driving modulation modular is connected with the input end of the laser source module, the output end of the micro scanning mirror control module is connected with the input end of a simulated micro scanning mirror, and the laser emitted by the laser source module is projected on the movable reflection mirror surface of the micro scanning mirror, and then is project on the surface of the human body after being reflected by the movable reflection mirror surface. The system provided by the invention has a structure simple; and by utilizing the system, focus-free projection image is realized, and the image can be clearly displayed on the concave-and-convex surface, such as the surface of the human body.

Description

technical field [0001] The invention relates to a surgical operation system assisted by medical image projection, in particular, one or more medical images are projected on the surface of a patient's body by using a focus-free micro-laser scanning projection device to provide accurate positioning for surgical operations. Lesions are provided for reference. Background technique [0002] In the past few decades, the rapid development of medical imaging, such as ultrasound, CT, MRI, PET (positron emission tomography), SPECT (single photon emission tomography), etc., and the integration with computers, signal processing technology and robotics Closely combined to give birth to a new discipline - computer-assisted surgery (CAS, Computer Assisted Surgery) technology. The use of CAS technology can accurately locate the lesion and significantly improve the safety of the operation. The core technical challenge of the current CAS technology is how to apply real-time medical imaging ...
