A kind of disposable gastroscope that can partially reuseTechnical field
The present invention relates to technical field of medical treatment mechanical, and in particular to the disposable gastroscope that one kind can be reused partially.
Background technique
Gastroscopy amount is big, although and existing reusable gastroscope good imaging quality, because of expensive, quantityFew, so can not meet medical demand, there are cross-infection risks, thus disposable gastroscope has the market demand.
A kind of disposable gastroscope of tradition uses bushing type, i.e., the surface cover one disposable protection outside reusable gastroscopeSet, the disadvantage is that, since protective case needs to cover the instrument channel inside gastroscope outer surface and gastroscope, and instrument channel is long and narrow(2.8mm internal diameter, 1.5m long) is accordingly difficult to wear in situations in the surgery room, influences popularity rate.Another disposable gastroscope of tradition usesIt is deserted, i.e., the work department of handle front end is all abandoned, the disadvantage is that, use cost is high or image quality is poor, because abandoningThe imaging modules that the cost is relatively high and it is at high cost, or use the imaging modules of cheap image quality difference.
Existing disclosed disposable gastroscope scheme, is perhaps not achieved using cumbersome perhaps too expensive or image qualityThe level of reusable gastroscope, it is difficult to universal.
Summary of the invention
