The purpose of the present invention is to provide a disposable endoscope system to solve the problems of high cost and poor imaging effect of the disposable endoscope system in the prior art.

In order to realize the above idea, as shown in FIG. 1, the present invention provides a disposable endoscope system, including a light source 10 and a hand piece 30, and also includes: The insertion part 40 extends from the proximal end of the handpiece 30 to connect with the light source 10; the connection part 20 includes a reusable first optical fiber; the insertion part 40 includes a disposable The second optical fiber; the first optical fiber and the second optical fiber are connected in the hand piece 30; the light emitted by the light source 10 enters the second optical fiber after passing through the first optical fiber.

In this embodiment, the optical fiber of the endoscope is split into two sections, which are a reusable first optical fiber at the front end of the handpiece 30 and a disposable second optical fiber at the rear end of the handpiece 30. In this way, the light source 10 The optical fiber section between the handpiece 30 and the handpiece 30 can be reused because it will not enter the subject, and will not cause cross-contamination, while the optical fiber section behind the handpiece 30 is a disposable second optical fiber, which can be discarded after one use The cross-contamination caused by repeated use can be avoided, and the disposable optical fiber section after the handpiece 30 generally occupies 1/3 to 1/2 of the entire optical fiber, and only the second optical fiber section needs to be replaced after each use. Compared with prior art disposable endoscope systems that require the entire length of optical fiber to be discarded, the cost is greatly reduced.

Preferably, the first optical fiber is a reusable glass optical fiber. Disposable endoscope systems in the prior art generally use low-cost plastic optical fibers in order to save costs, but the light sources used in endoscope lighting systems are generally xenon lamps, and the temperature of xenon lamps is relatively high. High temperature resistance, too high light source temperature will have an adverse effect on the plastic optical fiber, and the energy loss transmitted by the light source in the plastic optical fiber is also large, and the light transmission efficiency is low.

For example, the first pipeline includes a reusable first cable, a first water vapor pipeline and a first embedded pipe, and the second pipeline includes a disposable second cable, a second water vapor pipeline and a Second embedded pipe.

Further, this embodiment also includes an image sensor, the image sensor is arranged at the end of the second cable away from the hand piece 30 and is in signal conduction with the second cable, and the image sensor is used for collecting spectral signals , and convert the spectral signal into an electrical signal and transmit it through the second cable. In the embodiment, the light emitted by the light source 10 is transmitted through the first optical fiber and the second optical fiber, and finally irradiates the detection site of the subject. The image sensor can collect the spectral signal reflected from the surface of the detection site, and convert After the electrical signal is formed, it is transmitted through the second cable.
