Orbital endoscopic navigation surgery operation system based on eye tracker

Abstract

The invention provides an orbital endoscopic navigation surgery operation system based on an eye tracker. The orbital endoscopic navigation surgery operation system based on the eye tracker comprisesan endoscope supporting robot, a display, the eye tracker and a processing unit; an endoscope capable of acquiring an image of an operating area is clamped at the end part of the endoscope supportingrobot; the endoscope supporting robot is used for controlling movement or zooming of the lens of the endoscope by receiving a control instruction; the display is electrically connected with the endoscope supporting robot, and used for displaying the image of the operating area acquired by the endoscope; the eye tracker is used for acquiring eye movement data of a doctor in real time, and obtainingthe visual field coordinate position and the fixation duration of the doctor correspondingly falling on the screen of the display by conversion according to the eye movement data; and the processingunit is used for judging an interest operating area of the doctor according to the visual field coordinate position and the fixation duration, so that a control instruction is adaptively generated tocontrol the endoscope supporting robot to adjust the image of the operating area acquired by movement or zooming of the lens of the endoscope. By means of the orbital endoscopic navigation surgery operation system based on the eye tracker in the invention, in a condition that the doctor does not replace surgical instruments other than the endoscope in the hand, the position and the posture of theendoscope are autonomously changed according to the visual field will of the doctor; and thus, the operation efficiency is increased.

Description

technical field [0001] The present application relates to the technical field of orbital surgery equipment, in particular to an eye tracker-based orbital endoscopic navigation surgery operating system. Background technique [0002] In the operation of orbital endoscopic navigation surgery, the operation area in the deep position such as the orbital apex is narrow, the structure is complex, and the important structures are crowded, so an endoscope with a camera is usually required for observation. However, the chief surgeon often needs to hold instruments with both hands to expose the surgical field, instead of holding a mirror in one hand and instruments in the other. In this case, surgical assistants are often unable to quickly and accurately adjust and control the position and posture of the endoscope according to the wishes of the chief surgeon in a timely manner, wasting a lot of surgical time. [0003] There are other existing technologies that can display the gaze fie...
