Disposable endoscope sheath

Abstract

The invention provides a disposable endoscope sheath, which comprises an endoscope cavity, wherein the front end of the endoscope cavity is provided with an open opening; an annular limiting stage is arranged in the opening; the inner diameter of the limiting stage adapts to that of the endoscope cavity; and the front end of the endoscope cavity is provided with a transparent visible protective sheet for enclosing the endoscope cavity close to the back end of the limiting stage. The disposable endoscope sheath has the advantage and positive effect: the front end of the endoscope cavity is provided with the limiting stage, so that accidental injury to a patient due to possible fall of the transparent visible protective sheet at the front end caused by excessively large length of an endoscope or automatic fall of the transparent visible protective sheet into the body of the patient due to over long using time is avoided.

Description

Technical field [0001] The invention relates to a medical device, in particular to a disposable endoscope sheath. Background technique [0002] In the medical field, such as urology, when performing internal inspections or minimally invasive operations on relevant parts of the human body, not only endoscopes are often used, but also some surgical instruments may be required to enter the human body and cooperate with the endoscope to complete the corresponding diagnosis or treatment. Therefore, there is a need for a sheath that can accommodate both endoscopes and surgical instruments. [0003] The Chinese patent with the authorization announcement number CN100569175C discloses a disposable cystoscope sheath. This solution provides a dual-channel sheath structure that can simultaneously accommodate endoscopes and surgical instruments into the human body for diagnosis and treatment. The transparent visible protective sheet is sealed. When in use, the endoscope is inserted into the en...

[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 accommodating endoscopes and surgical instruments into the human body for diagnosis and treatment. The transparent visible protective sheet is closed. When in use, the endoscope is put into the cavity of the speculum. The eyepiece end of the endoscope should be close to the closed front end of the cavity of the speculum without limit. However, because the endoscope is too long, it may push off the front end. The transparent visible protective sheet, or the transparent visible protective sheet may automatically fall into the patient's body due to long-term use, thereby causing accidental injury to the patient; When the inside of the human body is squeezed, its end will block part or all of the transparent window of the endoscope cavity, which will affect the observation of the endoscope, thereby affecting the diagnosis and treatment process and effect
