Disposable endoscope sheath with self-destruct locking device

Abstract

The invention relates to a disposable endoscope sheath with a self-destructing endoscope-locking device, which comprises an endoscope tract and an endoscope bridge, wherein the endoscope tract is connected and communicated with the endoscope bridge; the tail end of the endoscope bridge is provided with a self-destructing sheath endoscope-locking device; the self-destructing sheath endoscope-locking device comprises an endoscope bridge port, an endoscope-locking sleeve, a locking shift lever, a locking clamping ring and a disposable connecting loop which are arranged at the tail end of the endoscope bridge; the endoscope-locking sleeve and the locking clamping ring are connected into an integrated body through the disposable connecting loop; the outside of the locking clamping ring is connected with the locking shift lever; a clamping sheet of the locking clamping ring is matched with a locking groove of the endoscope locking port; and the outside of the tail end of the endoscope bridge is sequentially provided with unidirectional teeth and threads, and is matched with inner bore unidirectional teeth of the endoscope-locking sleeve and connected with the endoscope-locking sleeve through threads. The endoscope can only disposably installed in the endoscope sheath and locked by the endoscope-locking device; and after the operation inspection, the disposable connecting loop of theendoscope-locking device must be dismounted and damaged so as to take the endoscope out of the endoscope tract, thereby ensuring that the endoscope sheath can not be used repeatedly.

Description

technical field [0001] The invention relates to a medical device, in particular to a disposable endoscope sheath with a self-destructing mirror locking device. Background technique [0002] In the medical field, the technology of minimally invasive diagnosis and treatment using medical endoscopes has been rapidly popularized and developed. In order to avoid cross-infection in clinical applications, and to reduce the adverse effects on the performance of endoscopes caused by repeated disinfection, more and more disposable endoscope accessories are used in conjunction with endoscopes and play an isolation role. It has been developed and applied to gradually replace reusable instruments, such as disposable endoscope sheaths and other products. However, the biggest risk of disposable medical instruments is infection caused by repeated use. How to prevent and avoid these disposable endoscope accessories from being Intentional or unintentional reuse is a new problem faced by new ...

In order to avoid cross-infection in clinical applications, and to reduce the adverse effects on the performance of endoscopes caused by repeated disinfection, more and more disposable endoscope accessories are used in conjunction with endoscopes and play an isolation role. It has been developed and applied to gradually replace reusable instruments, such as disposable endoscope sheaths and other products. However, the biggest risk of disposable medical instruments is infection caused by repeated use. How to prevent and avoid these disposable endoscope accessories from being Intentional or unintentional reuse is a new problem faced by new disposable products

[0003] A Chinese patent specification whose authorized notification number is 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. Although there is a locking mechanism at the end of the mirror bridge, this locking mechanism can be reused after the endoscope is removed after the operation, which is easy to cause infection; in addition, the surgical instruments protruding from the instrument channel may be damaged due to their own deformation stress or When the inside of the human body is squeezed, 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
