Initialization adjusting device for detecting optical performance of medical endoscope

Abstract

The invention discloses an initialization adjusting device for detecting the optical performance of a medical endoscope. The initialization adjusting device comprises a first angle adjusting device (5) for adjusting the angle of an endoscope, a second angle adjusting device for adjusting the angle of a measuring mark plate, a linkage mechanism (7) for realizing synchronous linkage of the first angle adjusting device and the second angle adjusting device, and an angle fine adjusting structure (8) for finely adjusting rotation of the linkage mechanism (7). According to the invention, the adjustment to the nominal visual angle can be realized by rotating the endoscope and the measuring mark plate synchronously at a 1/2 visual angle, so that the adjustment efficiency is improved; because of rotation of the endoscope and the measuring mark plate, the measuring mark plate only needs to be rotated within the range of 0 to 50 degrees, so that the adjustment range is reduced and the structuraldesign is simplified. The adjustment requirement of the visual direction angle of 0 to 90 degrees is met; the initialization adjustment requirement of the large-angle visual direction angle endoscopeis met; and the adjustment efficiency is improved.

Description

technical field [0001] The invention relates to the field of optical equipment detection, in particular to an initialization adjustment device for medical endoscope optical performance detection. 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 endosc...

Problems solved by technology

However, since the angle of view of most medical rigid tube endoscopes ranges from 0° to 90°, and the existing structure simply adjusts 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°), the adjustment of the target plate is more complicated and cannot meet the needs of rapid adjustment, which reduces the early stage of the process of testing the optical performance of the medical rigid tube endoscope. work efficiency
