Abstract

The invention relates to a disposable locking structure of an endoscope sheath. The disposable locking structure comprises the endoscope sheath, an intermediate sleeve, a locking sleeve and a connector of the endoscope sheath and an endoscope, and the intermediate sleeve and the locking sleeve are sleeved on the endoscope sheath at the position of the connector to lock the endoscope. The connector of the endoscope sheath and the endoscope is in a shape wide in the left and right ends and narrow in the upper and lower portions, and a positioning groove is formed in the connector. One end of the endoscope sheath is provided with a circular positioning pin, a safety switch is arranged on the intermediate sleeve, two flanges are arranged on the circle of one end of the locking sleeve, and a positioning pin is arranged at the other end of the locking sleeve. After locking, a rotation angle is generally within a range from 70 degrees to 110 degrees, but not limited to the degrees. The disposable locking structure is mainly used for locking the endoscope connector, and applicable to endoscopes identical in connector but different in brands. The designed disposable locking structure of the endoscope sheath is adaptable to characteristics of disposable products, capable of effectively preventing the disposable endoscope accessories from being reused intentionally or unintentionally, simple in structure and easy for mass production.

Description

technical field [0001] The invention relates to a medical device, in particular to a locking structure of an endoscope sheath. 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 intentionally or unintentionally is a new problem faced by new disposable products. [0003] The applicant ...
