Endoscope system with disposable sheath

Abstract

The present invention belongs to the field of medical equipment, and the endoscope system with disposable sheath includes endoscope body and open-ended pipe. The endoscope system features that it has one isolating sleeve bag of transparent and tough material to cover the endoscope body and connected pipes set outside the isolating sleeve bag. After being used, the isolating sleeve bag together with the outside pipes is disposed while the expensive endoscope body is sterilized for reuse. The present invention can raise the utilization of the endoscope and prolong its service life.

Description

technical field [0001] The invention relates to an endoscope, in particular to an endoscope system with a disposable sheath, which belongs to the technical field of medical instruments and is suitable for use in various hospitals. Background technique [0002] As an important means of minimally invasive surgery, intuitive exploration and unique photopic biopsy function to provide evidence for diagnosis, medical endoscope has become an irreplaceable technology in the field of modern medicine. However, the iatrogenic pollution that can be produced by the above-mentioned biopsy process cannot be ignored, especially in recent years, the fear of blood virus transmission is daunting! For this reason, people change many small medical instruments into one-time use as much as possible, but medical endoscopes are not suitable for one-time use because of their high cost. Endoscopes are used as interventional instruments, and disinfection is indeed a big problem. Endoscopes can be ster...

However, the iatrogenic pollution that can be produced by the above-mentioned biopsy process cannot be ignored, especially in recent years, the fear of blood virus transmission is daunting! For this reason, people change many small medical instruments into one-time use as much as possible, but medical endoscopes are not suitable for one-time use because of their high cost. Endoscopes are used as interventional instruments, and disinfection is indeed a big problem. Endoscopes can be sterilized by the newly developed high-temperature disinfection method, but all kinds of flexible mirrors cannot withstand high-temperature disinfection, and the various openings in the endoscope cannot be thoroughly cleaned and disinfected, such as biopsy forceps. The danger of being contaminated can be imagined

For this reason, since the nineties in the 20th century, people at home and abroad have begun to explore solutions, wherein the more feasible ones are U.S. Patent No. 5,025,778 and No. 5,876,329. They have their own characteristics, but they all have their difficult implementation. No. 5,025,778 gives the schematic structure of the embodiment: the pipeline "54" shown in Figure 2B is composed of two layers of material, and the front opening is open, which is easy to scratch the body cavity mucous membrane; the pipeline "54" shown in Figure 8 is the opposite. The tube is closed, the tube is very long, the process of inserting the instrument is not smooth, and the tube is in danger of being punctured

However, U.S. Patent No. 5,876,329 provides the diagrammatic structure of the embodiment. The endoscope is made into a C-shape, and the flexible mirror needs to be bent and turned. sale and use
