Method for detecting optical performance of medical endoscope

Abstract

The invention discloses a method for detecting the optical performance of a medical endoscope. A medical hard tube endoscope (1) is fixedly clamped on a fixing device (3); a measuring mark plate (9) is fixed on a measuring mark mounting plate (66); and the medical hard tube endoscope (1) is horizontally arranged and the measuring mark mounting plate (66) is vertically arranged. The fixing device (3) is controlled to rotate anticlockwise and the measuring mark mounting plate (66) rotates clockwise simultaneously, wherein the rotation angle of the fixing device (3) is the same as that of the measuring mark mounting plate (66); and when the rotation angles of the fixing device (3) and the measuring mark mounting plate (66) are one half of a nominal visual angle, preliminary angle adjustment is completed. According to the invention, the system for detecting the optical performance of a medical endoscope has a simple structure and the adjustment requirement of the visual angle of 0 to 90 degrees is met by the operation; and the adjustment efficiency is improved.

Description

technical field [0001] The invention relates to the field of optical equipment detection, in particular to a method for detecting the optical performance of a medical endoscope. Background technique [0002] With the rapid development of medical technology, medical electronic endoscopes can flexibly enter various cavities of the human body and display images of the cavities of the human body with high definition, so they are widely used clinically. However, as the technology becomes more widespread, its optical properties have a crucial impact on patient diagnostic safety. In response to this problem, the country and the industry have jointly formulated testing standards, so as to achieve the purpose of daily maintenance, testing reception and fault diagnosis of its optical performance, so that the electronic endoscope is always in the best performance state and reduces its quality problems resulting in medical malpractice. Due to the importance of endoscope optical perfor...

However, since the angle of view of most medical rigid tube endoscopes ranges from 0° to 90°, the existing structures simply adjust the angle of the target plate to adapt to the viewing angle of the medical rigid tube endoscope. However, when the angle range of the viewing angle of the medical rigid tube endoscope is too large (greater than 45°), and the rotation angle of the target plate of most detection equipment can only reach 60° at most, and the adjustment of the target plate is more complicated , unable to meet the needs of rapid adjustment, reducing the early work efficiency in the process of testing the optical properties of medical hard tube endoscopes
