Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical instrument detection, in particular to a testing device and testing method for light radiation hazards of a medical endoscope system. BACKGROUND

[0002] As the core equipment for clinical examination, surgical operation and microsurgical operation, the medical endoscope system has a low thermal energy light emitting characteristic, which can effectively avoid thermal damage to patient tissues and precision instruments, and has been widely used in diagnosis and treatment of multiple sites such as body cavity, eye, body surface skin and teeth. As a Class II medical device, the risk control of its light radiation hazards is particularly critical, which is directly related to the safety protection of human skin and mucosa.

[0003] The existing light radiation risk assessment standard (such as GB / T20145-2006) mainly aims at thermal radiation type light sources and beauty type light sources, and adopts a test distance of 200mm as the basis of the emission window. However, when the medical endoscope system works in the abdominal cavity, it is often in close contact or very close distance with the tissue, and the use of 200mm test distance will result in that the test result cannot truly reflect the radiation hazard level of the abdominal cavity skin and mucosa, causing significant deviation in risk assessment in the actual clinical scene. Although the light radiation risk classification test method of the existing lamp and lamp system can cover most products, it cannot simulate the special use environment of the medical endoscope in the body cavity, resulting in lack of accuracy and pertinence in the light radiation hazard assessment of the medical endoscope.

[0004] Therefore, it is urgent to develop a testing device and method that can simulate the actual clinical use state to fill the technical gap in the light radiation hazard test of the medical endoscope system, and provide a reliable basis for its quality detection and risk prevention and control.
