AI Technical Summary

Problems solved by technology

Traditional endoscopes are monocular, and doctors perform operations by observing single-channel 2D images.
2D images cannot give doctors an intuitive sense of three-dimensionality, so that the intensity of the doctor's operation becomes larger and the accuracy of the operation is not high
At present, these technologies already have mature products, but none of the existing solutions can meet the requirements of stereoscopic vision display in laparoscopic surgery

Embodiment 1

[0029] Such as figure 1 As shown, the binocular endoscopic surgical vision system of the present invention is mainly composed of three parts: binocular endoscope, image server and endoscope stereoscopic display unit, wherein,

[0030] Part I: Binocular endoscope,

[0031] including such as image 3 The binocular endoscope shown includes a binocular endoscope main body, a dual-channel cold light source and a camera. The dual-channel cold light source provides dual-channel illumination for the camera to ensure image brightness and uniform illumination of the acquired image. The binocular endoscope in the present invention is illuminated by a dual-channel xenon cold light source, and the camera controller has the functions of photometric area selection and white balance, and provides an S-terminal video output interface to connect to an image server.

[0032] The concrete structure of described binocular endoscope comprises, binocular endoscope tube body, is provided with two ...

Embodiment 2

[0050] Embodiment 2: Laparoscopic surgery stereo vision system simulation working process:

[0051] The present invention is illustrated by a complete stereoscopic vision forming process below:

[0052] The first step: hardware system preparation

[0053] Fix the binocular endoscope with a modified ordinary camera tripod, so that the endoscope and the observation plane form an angle of about 30°, and the end of the binocular endoscope is 4cm away from the target object. Place the binocular endoscope in this way, It is to simulate the position of the binocular endoscope in the abdominal cavity in the laparoscopic operation environment; connect the light entrance component 9 of the binocular endoscope to a xenon cold light source. The end image signal cable is connected to the camera controller (omitted in the figure). The two camera controllers are respectively connected to the S terminal of the image server through connecting wires, and the liquid crystal display of the ster...

Abstract

A binocular endoscope operation visual system mainly comprises a binocular endoscope, an image server and an endoscope stereo display unit. Two ways of clear abdominal cavity image video signals are obtained by the binocular endoscope, two ways of video streams enter a memory of an image processing server or a video memory by a two-way image capture card, and a left-way image and a right-way image which are processed are respectively displayed in a left displayer and a right displayer. By a flat mirror, the contents of the left displayer and the right displayer respectively enter the left eye and the right eye of an observer, thereby the stereo effect is realized. The binocular endoscope operation visual system is suitable for the circumstance of a medical surgical endoscope operation, can completely satisfy the stereoscopic vision requirement of a laparoscope operation of a minimally invasive operation robot, realizes the binocular stereoscopic vision real-time display in the laparoscope operation, has reliable performance, simple structure and high commercialization level, and adapts the germfree circumstances of the operation.

Description

【Technical field】: [0001] The invention belongs to the field of endoscopic stereo vision, and particularly relates to a stereo vision system for medical robots in the field of minimally invasive abdominal cavity. 【Background technique】: [0002] At present, the research on medical robot technology has become one of the frontier research hotspots in the field of international robotics, among which the research on medical and surgical robots is the most prominent. In recent years, medical staff have worked closely with scientific, engineering and technical personnel to research and develop many types of medical surgical robot systems, some of which have been well applied in clinical practice. Such as the daVinci surgical robot system developed by Intuitive Surgical Company of the United States. Before the advent of the da Vinci system, Computer Motion developed a powerful vision system based on the AESOP series of robots developed by Computer Motion in 1996, and launched the ...
