Disposable endoscope sheath

Abstract

The invention provides a disposable endoscope sheath which comprises a sheath tube composed of respectively independent endoscope cavity and appliance channel, wherein the front end of the endoscope cavity is provided with a transparent window for sealing the endoscope cavity, the front end of the appliance channel is in an open type, a switching wire channel is arranged between the endoscope cavity and the appliance channel, a switching wire penetrates through the switching wire channel, front and rear parts of the switching wire extend out of the switching wire channel, and a switching component is connected to the front end of the switching wire. The disposable endoscope sheath provided by the invention has the beneficial effects that: the switching component is clamped between the part, extending out of the appliance channel, of an operation appliance and the sheath tube, and is used for switching the switching wire backwards and forwards, so that the switching component is drivento move backwards and forwards, an appliance head of the operation appliance is agilely adjusted at a pitch angle and the operation appliance is operated, thus illness inspection and surgical operation are simultaneously carried out; and in addition, the length of the endoscope cavity channel isolated by a metal tube is properly adjusted, thus the problem of inconvenient connection of endoscopes with different working length is solved, and the strength of the sheath is enhanced at the same time.

Description

technical field [0001] The present invention relates to a medical device, in particular to a disposable medical device capable of accommodating an endoscope and a surgical device at the same time, the position and angle of the surgical device can be adjusted flexibly, and endoscopes of different working lengths can be easily connected to the sheath. mirror 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 addition, in the past, some endoscope accessories that helped endoscopes and instruments enter the human body were mostly made of stainless...

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; secondly, the surgical instruments protruding from the instrument channel may be Due to its own deformation stress or internal extrusion of the human body, 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

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 endoscope cavity, which affects the observation field of view. Both of the above two items cause the endoscope to be unable to use normally.
