Disposable double-passage endoscope sheath

Abstract

The invention provides a disposable double-passage endoscope sheath. The disposable double-passage endoscope sheath comprises a sheath pipe consisting of an endoscope cavity and an instrument passage which are independent of each other; the front end of the instrument passage is provided with an opening; a stirring wire passage is formed between the endoscope cavity and the instrument passage; a stirring wire passes through the stirring wire passage and the parts of front and back parts of the stirring wire are exposed out of the stirring wire passage, and the front end of the stirring wire is connected with a stirring part; and the stirring part is a roller part or an inverted concave steel wire part. The disposable double-passage endoscope sheath has the advantages that: a head of surgical equipment is flexibly adjusted, so that the condition of a patient is checked and surgery can be performed simultaneously; the working length of an endoscope can be adjusted, and the problem that endoscopes with different working lengths are inconvenient to connect is solved; a surgical part is supported by conveying water through a water inlet passage before surgery, and impurities on the surgical parts are discharged through a water discharge passage to ensure that surgical fields are clear and visible, and the surgery is accurate; and the whole disposable double-passage endoscope sheathis disposable, avoids pollution and is safe and sanitary.

Description

technical field [0001] The invention relates to a medical device, in particular to a disposable double-channel endoscope sheath which can accommodate both an endoscope and a surgical device and whose position and angle of the surgical device can be flexibly adjusted. 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 addition, in the past, some endoscope accessories that helped endoscopes and instruments enter the human body were mostly made of stainless steel, which can be repeatedly sterilized and used in combination. , scissors and other surgical i...

AI Technical Summary

Problems solved by technology

The problems of using the above-mentioned combined accessories are: firstly, repeated use and multi-piece combined instruments are likely to cause cross-infection of patients due to incomplete disinfection; secondly, doctors need to be familiar with the use of instruments when assembling various accessories during inspection and surgery, which is cumbersome and complicated. Increased workload and prolonged operation time

[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, but the sheath structure simultaneously There are also problems: First of all, the adjustment of surgical instruments in diagnosis and treatment is very limited, and can only be adjusted forward, backward and around its axis, and the working range is small

In addition, because 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. 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 connection part of the endoscope to not be locked in place, and the connection cannot be realized; An inappropriate distance is formed between the transparent and visible protective sheets at the front end of the speculum cavity, which affects the observation field of view. Both of the above two items cause the endoscope to not work normally.

Secondly, 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
