Title:
ALL-DIRECTION-ADJUSTABLE AND POSITION-DISPLAYING ELECTRONIC ENDOSCOPE
Document Type and Number:
WIPO Patent Application WO/2024/016316
Kind Code:
A1
Abstract:
An all-direction-adjustable and position-displaying electronic endoscope, comprising an endoscope assembly, a housing, a display and a controller. During adjustment, first a virtual position model of the endoscope is established; the position at which the endoscope is located when all traction lines are in stress balance is set as an original point, the position of the original point being displayed on the display; when a joystick is swung to turn the endoscope, the controller calculates displacement information of the endoscope according to stress information of the traction lines transmitted by displacement sensors; and according to the position of the original point, the movement position coordinates of the endoscope are displayed on the display in real time. During use, the joystick is swung so as to adjust the angle of the endoscope within 360° by adjusting the degree of tightness of the traction lines, and the position information of the endoscope is displayed on the display in real time; meanwhile, an observation image obtained by the endoscope can be displayed on the display, such that detected condition of diseases can be accurately determined according to both said image and the position information. The problem that during turning adjustment of existing endoscopes, accurate and real-time position displaying with respect to the adjustment position coordinates of the endoscopes cannot be achieved is solved.
