Improved disposal endoscope sheath

Abstract

The invention provides an improved disposal endoscope sheath. The endoscope sheath comprises a sheath casing, a sheath main body and an endoscope bridge which is connected in the sheath main body, wherein the rear end of the sheath casing is connected with the sheath main body, and is isolated by a metal tube to form an independent metal endoscope cavity; the front end of the sheath casing is an opening port which is provided with an annular spacing stand; the annular inner diameter of the spacing stand adapts to the inner diameter of the metal tube which forms the endoscope cavity; a sealed transparent visible protective plate is arranged at the front end of the metal tube in the sheath casing, and keeps a certain adjustable distance with the front end of the sheath casing; and an endoscope locking device is arranged at the rear end of the endoscope bridge. The improved disposal endoscope sheath has the advantages and positive effects that: the length of the endoscope cavity which isisolated by adopting the metal tube can be adjusted appropriately, so that the problem that endoscopes with different work lengths are not convenient to connect is solved, the strength of the sheath is increased, and the sealing property is good; and furthermore, the endoscope can be arranged in the sheath only once and locked by the endoscope locking device, so that the endoscope sheath is prevented from being repeatedly used.

Description

technical field [0001] The invention relates to a medical device, in particular to an improved disposable endoscope sheath. Background technique [0002] In the medical field, such as urology, when performing inspections or minimally invasive operations on relevant parts of the human body, not only endoscopes are often used, but some surgical instruments may also need to enter the human body at the same time to cooperate with the endoscope to complete the corresponding diagnosis or treatment. , therefore need a kind of mirror sheath that can hold endoscope and surgical instrument simultaneously. In order to prevent the endoscope from being contaminated by instruments, the endoscope cavity and the instrument channel of the disposable endoscope sheath are independently isolated. [0003] The Chinese patent with the authorized notification number CN100569175C discloses a disposable cystoscope sheath, which provides a dual-channel sheath structure capable of simultaneously acco...

AI Technical Summary

Problems solved by technology

Since the front end of the endoscope cavity is rigidly closed, the overall length of the endoscope cavity cannot be changed, and there are certain differences in the length of the working part of different endoscopes, and the following problems will occur: First, when the endoscope is installed into the endoscope When the front end of the mirror cavity is in place, it is very easy to cause the mirror locking device at the end of the mirror bridge and the connecting part of the endoscope to fail to lock in place, and the connection cannot be realized. If the endoscope is too long, it may damage the transparent and visible front end of the mirror cavity. The second is that although the endoscope and the end of the mirror bridge are locked, there is an unsuitable distance between the front end of the endoscope and the transparent and visible protective sheet at the front end of the endoscope cavity, which affects the observation field of view. Endoscope not working properly

In addition, there is also a problem that although the end of the mirror bridge of the mirror sheath is provided with a locking mechanism, the locking mechanism can be reused after the endoscope is removed after the operation, which is easy to cause infection
