Abstract
The utility model discloses a detecting device for quality performance of a medical endoscope. The detecting device comprises a guide rail, a rotating table, a uniform light source, a target, a supporting rod, a video acquisition device, and a computer. The rotating table, the supporting rod and the support of the video acquisition device are sequentially arranged on the guide rail. The uniform light source is fixed on the rotating table. The medical endoscope is arranged on the supporting rod. The target is arranged between the uniform light source and the medical endoscope. The video acquisition device is connected with the computer. When the uniform light source lights the target, the video acquisition device collects data through the medical endoscope, and the computer is used to process so that quality performance parameters of the medical endoscope can be obtained. Compared with the prior art, the detecting device can integrally, automatically and quantificationally detect various quality performance parameters of the medical endoscope.
