Prism-based medical endoscope system with measurement function and method

Abstract

The invention discloses a prism-based medical endoscope system with a measurement function and a method, relating to a medical endoscope which comprises an endoscope device and a computer, wherein the endoscope device comprises an endoscope body, a handholding part, a miniature camera, a direct current voltage stabilizing power supply, a cold light source, an image acquiring card, a light guide optical fiber and a calibration plate, wherein the endoscope device also further comprises a prism and a prism fixing device, wherein the prism fixing device is arranged at the front end of the inside of the endoscope body and is provided with a rectangular hole, the axial line of the rectangular hole is coincident with the axial line of the endoscope, a slot is formed in the tail end of the rectangular hole, the prism is arranged in the rectangular hole and is fixed by the slot. By using the prism-based medical endoscope system, images of internal organs and tissues of a human body can be clearly displayed, and actual lengths of appointed objects can be measured. Because an accurate three-dimensional vision flow is adopted, the obtained result accuracy is relatively higher.

Description

technical field [0001] The invention relates to a medical endoscope, in particular to a prism-based medical endoscope system and method with measuring functions. Background technique [0002] In recent years, minimally invasive surgery (Minimally Invasive Surgery) has gradually penetrated into various fields of surgery. The surgeon only needs to make a small hole in the patient's body, and the internal organs can be seen through the endoscope, and the internal operation of the human body can be performed in the form of direct observation. Compared with traditional surgery, it can not only reduce the pain of patients, but also greatly shorten the recovery time of patients, improve the efficiency of surgery and save the cost of surgery. [0003] Medical endoscopy has played an important role in the progress of modern medicine. However, the existing medical endoscopy and minimally invasive surgery use two-dimensional endoscopes that can only display flat images, which is not ...

AI Technical Summary

Problems solved by technology

But the prerequisite is that two video capture units are needed, which inevitably increases the volume and complexity of the entire video capture system

Its scope of application is greatly limited

In addition, even if the three-dimensional image of the lesion and tissue in the patient can be seen intuitively, the doctor can only rely on experience and feeling to judge its specific size, so as to choose the appropriate type of surgical tool for excision or suture, etc. It is also difficult to avoid adverse consequences caused by misjudgment
