Optical coherence tomography based microsurgical operation system and navigation method

Abstract

The invention discloses an optical coherence tomography based microsurgical operation system and a navigation method. The microsurgical operation system comprises an objective lens, an operation microscope unit, an optical coherence tomography unit, a processor and an output unit. The operation microscope unit is configured to perform two-dimensional imaging in an operative region via the objective lens. The optical coherence tomography unit is configured to perform two-dimensional tomography imaging in the operative region via the objective lens, and an imaging view of the optical coherence tomography unit is calibrated according to an imaging view of the operation microscope unit. The processor is configured to acquire navigation information on the basis of a two-dimensional imaging result of the operation microscope unit and a two-dimensional tomography imaging result of the optical coherence tomography unit, and the navigation information includes information of the operation region for performing operation and positions of surgical instruments used for operation on the operative region. The output unit is configured to output navigation information to guide the operation instruments to reach the operative region.

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...

AI Technical Summary

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.
