Problems solved by technology

[0007] At present, minimally invasive surgery mainly uses endoscopy, which is displayed on the monitor for doctors to observe. During observation, doctors need to constantly move their eyes at the surgical site and the monitor bracket, which affects the continuity of the operation and is prone to fatigue. In view of the above shortcomings, some researches The latter adopts the patient's body surface projection method based on augmented reality technology (Augmented Reality AR), and uses a projector to project the image captured by the endoscope on the patient's body surface, so as to assist the doctor's judgment when necessary and form a virtual epidermal transparency effect; but When doctors need large-scale observation or local observation, assistants are needed to assist in holding and adjusting body surface projection images, which will affect the continuity of surgery. For this purpose, an adjustment device for minimally invasive surgery body surface projection is provided. By detecting the doctor's leg The swing of the projection image is adjusted, and the virtual axis of human leg rotation needs to be adjusted coaxially with the hinge axis of the device during detection.

Abstract

The invention discloses an articulated shaft adjusting method for minimally invasive surgery body surface projection shaft adjustment, and belongs to the technical field of body surface projection adjustment and motion capture. According to the method, a length m is set, if c and d are different in sign, an articulated shaft is moved by one m length along a horizontal shaft, if c is a positive number and d is a negative number, the articulated shaft is moved rightwards, and if c is a negative number and d is a positive number, the articulated shaft is moved leftwards; if c and d are the same in symbol, the articulated shaft is moved by one m length along a vertical shaft, if c is a positive number and d is a positive number, the articulated shaft is moved downwards, and if c is a negative number and d is a negative number, the articulated shaft is moved upwards; and moving is stopped until the c and d symbols are the same. An axis adjustment method applied to the minimally invasive surgery body surface projection adjustment method has the advantages that the adjustment process is simple and automatic, the adjustment can be completed quickly, the adjustment time is saved, and the axis adjustment method adapts to doctors of different postures.

Description

[0001] This application is a divisional application of the invention patent application "Axis Adjustment Method Facing Minimally Invasive Surgery Body Surface Projection Adjustment Method". [0002] The original filing date: 2019-03-16. [0003] Original application number: 2019102002428. [0004] Invention name of the original application: Axis adjustment method for body surface projection adjustment method for minimally invasive surgery. technical field [0005] The invention belongs to the technical fields of body surface projection adjustment and motion capture, and in particular relates to a hinge axis adjustment method for body surface projection axis adjustment in minimally invasive surgery. Background technique [0006] Compared with traditional open surgery, minimally invasive surgery has the advantages of small wound, light pain, and fast healing, which caters to the aesthetics of modern people, so it has attracted more and more attention and is used in some abdom...
