Length-adjustable endoscope sheath with disposable locking mechanism

Abstract

The invention relates to a length-adjustable endoscope sheath with a disposable locking mechanism. The length-adjustable endoscope sheath comprises a disposable locking structure and a retractable sealing mechanism, wherein the disposable locking structure is located on the tail portion of the endoscope sheath, and the retractable sealing mechanism is located in a cavity of the endoscope sheath. The disposable locking structure comprises an endoscope sheath body, a middle-layer sleeve, a locking sleeve and a connector of the endoscope sheath body and an endoscope, wherein the middle-layer sleeve and the locking sleeve are arranged on the endoscope sheath body at the port in a sleeved mode to lock the endoscope. The retractable sealing mechanism comprises an endoscope pipe, a soft pipe and an endoscope bridge, wherein the endoscope pipe is arranged in the endoscope sheath body and is an endoscope body channel of the endoscope, the inner diameter of the soft pipe is smaller than that of the endoscope pipe under the condition that the soft pipe is not stressed, the diameter of the position, sleeving the endoscope pipe, on the endoscope bridge is larger than that of the endoscope pipe, one end of the soft pipe is arranged on the endoscope bridge in a sleeved mode, the other end of the soft pipe is arranged on the endoscope pipe in a sleeved mode, the endoscope pipe is inserted into an inner cavity of the endoscope bridge, and the connection portions of the endoscope bridge, the endoscope pipe and the soft pipe are in a sealed state. The endoscope sheath is simple and reliable in structure and facilitates actual production.

Description

technical field [0001] The invention relates to a medical device, in particular to an endoscope sheath which can not only have a self-destruction locking device but also can adjust the length according to different types of endoscopes. Background technique [0002] Non-disposable stainless steel surgical instruments are mainly used in conventional cystoscopic surgical instruments and hysteroscopic surgical instruments. At the same time, stainless steel metal surgical instruments are also non-disposable instruments due to their high cost and high cost. In order to prevent cross-infection, cleaner disposable sheaths have emerged as the times require. Its characteristic is that it can be exempted from disinfection, which is not only hygienic, but also saves time and eliminates the process of disinfection. However, the biggest risk of disposable medical devices is infection caused by repeated use. How to prevent and avoid these disposable endoscope accessories from being reused...

AI Technical Summary

Problems solved by technology

However, the biggest risk of disposable medical devices is infection caused by repeated use. How to prevent and avoid these disposable endoscope accessories from being reused intentionally or unintentionally is a new problem faced by new disposable products.

In addition, the disposable endoscope sheath requires complete sealing of the endoscope, and the length of endoscopes of different brands may be slightly different. How to ensure the sealing of endoscopes of different lengths is also an urgent problem to be solved

[0003] The applicant of this patent discloses a self-destruct mirror locking device in patent 102293628A, and a disposable endoscope sheath with a retractable mirror bridge is disclosed in patent 202218866U, but these structural forms are relatively complicated, not only It is not conducive to the operation of doctors, and it is not conducive to the actual large-scale industrial production
