Endoscope system of having one-off sheath

Abstract

An endoscope assembly with a disposable sheath, in which the open conduits of a conventional endoscope body are cancelled. The head of the endoscope is capsulized or reshaped and is covered by a isolated sheath (6), a elastomeric end cap (10) is provided outside the isolated sheath (6) to join the open conduits shifted out from the conventional endoscope body. The external diameter of the endoscope assembly does not enlarge therefore. The isolated sheath (6) and the external open conduits are disposed after use so that the endoscope assembly can be sterilized entirely. The present invention is used in all sorts of flexible and rigid magical endoscopes.

Description

technical field [0001] The invention improves the traditional medical endoscope, solves the problem of one-time disinfection, and proposes a complete endoscope system with a disposable sheath, which belongs to the technical field of medical equipment and is suitable for clinical use in hospitals. Background technique [0002] Medical endoscope can directly observe intracavitary lesions, biopsy and perform minimally invasive surgery. It not only provides evidence for diagnosis, but also removes lesions and eradicates diseases. It has become an irreplaceable important technology in the field of modern medicine. However, the iatrogenic infection that can be produced in the endoscopic examination process cannot be ignored, especially the possible occurrence of accidents such as transmission of hepatitis and AIDS through blood and body fluids is really worrying! In modern times, many small medical devices have been changed to one-time use as much as possible to completely solve t...

Problems solved by technology

However, medical endoscopes cannot be used for one-time use because of their high cost. However, as an interventional instrument, disinfection is indeed a big problem. Service life), but all kinds of flexible mirrors cannot withstand high temperature and high pressure disinfection at all, especially the various openings in the endoscope are more difficult to clean and disinfect thoroughly

In view of this, since the nineties in the 20th century, people both at home and abroad have begun to explore solutions, among which there are three U.S. patents (patent numbers: 5,025,778; 5,483,951 and 5,876,329) that are closer to the present invention. They have their own characteristics, but All have its difficulty in implementation, for example, although the U.S. Patent No. 5,025,778 provides the illustrated structure of multiple embodiments: wherein the structure shown in Figure 2B is a fully opened open pipe outside the casing, but due to its opening The opening of the front end of the pipeline 54 is open, which is easy to scratch the body cavity mucosa; the opening pipeline 54 shown in Figure 8 is the opposite, and the whole tube is in a closed shape. During the process, the pipeline is in danger of being punctured; and the US Patent No. 5,483,951 discloses a semi-cylindrical mirror body structure and the U.S. Patent No. 5,876,329 has an axial C-shaped endoscope mirror body structure. The common defect of sex mirrors is that it is difficult to manufacture, because soft mirrors need to be bent and turned, and free-bending non-cylindrical "snake bones" are not easy to make.

[0003] The cost of the sheath is also higher, which will definitely affect the sale and use of the product in the market, so there is no promotion so far in the market
