Microsurgery system guided by optical coherence tomography

Abstract

Provided are a microscopic surgery system and a navigation method guided by optical coherence tomography. The microscopic surgery system may include: an object lens; a surgical microscope unit configured to perform two-dimensional imaging on an area to operate on via the object lens; an optical coherence tomography unit configured to perform two-dimensional tomography imaging on the area via the object lens, with an imaging field calibrated according to that of the surgical microscope unit; a processor configured to obtain navigation information based on the two-dimensional imaging by the surgical microscope unit and the two-dimensional tomography imaging by the optical coherence tomography unit, the navigation information comprising positional information of a body part to operate on and a surgical instrument for operating on the body part; and an output unit configured to output the navigation information to guide the surgical instrument to the body part.

Description

technical field [0001] The present disclosure relates to microsurgery imaging and image processing, in particular, to a microsurgery system and navigation method based on optical coherence tomography guidance. Background technique [0002] Modern surgery has required that while accurately locating the surgical target site, the physiological trauma to the patient should be reduced as much as possible to achieve minimally invasive surgery, so as to overcome the large surgical trauma and long recovery period left over from the rough open surgery in the past. Defects, to minimize the physical and psychological harm to patients. Image-guided interventional surgery can accurately locate the surgical target, and can realize monitoring and navigation during the operation. It has the advantages of small trauma, fast recovery, and good curative effect. Trends in traditional open surgery. [0003] Most surgical procedures involve deep tissue. The traditional method is to cut open th...

Problems solved by technology

Although the resolution of the optical surgical microscope used in surgery has reached the order of several microns, there has been no three-dimensional (x-y-z stereoscopic imaging) imaging technology that can match the resolution.

In addition, the operating area of ​​microsurgery is very small, so factors such as vibration and tissue cutting during the operation will directly cause the overall deformation of the surgical area, so non-real-time imaging techniques such as magnetic resonance and CT are not applicable Navigation in Microsurgery

It is precisely because of the above problems that in the field of microsurgery, there has been no image navigation for surgery so far.
