Disposable endoscope sheath

Abstract

The invention provides a disposable endoscope sheath which comprises a sheath pipe. The sheath pipe comprises an endoscope cavity and an instrument channel which are independent. The front end of the instrument channel is of an opening type. A protrusion is arranged at the lower end of the sheath pipe. The lower end of the endoscope cavity is provided with an inserting groove, a sheath pipe protecting block, a lifting mechanism and a stopping table which is fixedly connected to the endoscope cavity. The sheath protecting block is inserted into the inserting groove. A blocking side of the inserting groove extends to the protrusion of the lower end of the sheath pipe. An arc designed in a smooth mode is arranged at the outer end of the sheath pipe protecting block, and the inner end of the sheath pipe protecting block is provided with a step. The disposable endoscope sheath has the advantages that the sheath pipe protecting block has a buffering and protecting effect as a first contacting part, the sheath pipe protecting block can be replaced according to needs, the purpose of biopsy instrument taking angle adjusting is achieved, the requirements for different situations can be met, the structure is simple, design is novel, machining cost is low, operation is flexible, and the adjusting angle is large.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a 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 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 instruments, but also pre-loaded instrument manipulator in the mirror sheath. In this way, even in uncomplicated inspection operations, at...

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 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, the working range is small, and the angle is not easy to control

Secondly, when the disposable endoscope is working, the sheath tube directly enters the human body, and there are no buffer and protection parts designed, so the insertion resistance of the sheath tube is relatively large
