Non-invasive anoscope operation auxiliary system

Technical Field

The application relates to a medical instrument, in particular to a noninvasive anoscope operation auxiliary system.

Background

In enteroscopy, such as colonoscopy, unlike the conventional surgical procedure in which an incision is made in the abdomen of a patient and a diseased tissue may be removed from the incision, an anal mirror is used to perform transanal diagnosis. Wherein, a part of anoscope operations need to inject air into the cavity to expand the intestinal canal so as to obtain good visual field, thereby achieving better diagnosis and treatment effects. However, the existing anoscope surgical instrument has poor fitting performance with the anus of a patient and is easy to expose air, particularly, the anus of a part of patients is loose, and the patients do not feel conscious when painless colonoscopy is used for diagnosis and treatment and cannot control the sphincter of the anus to prevent air from being exhausted, so that the injected air is easy to leak through the anus, insufficient air in an intestinal canal is caused, the intestinal canal is poorly expanded, the visual field of an operator is influenced, and even the enteroscopy cannot be performed.

In addition, in the process of an anoscope operation, the anoscope needs to be inserted or pulled out of the anus of a patient for multiple times and is operated by moving forward and backward, and the body of the anoscope can rub mucous membranes at the anus of the patient repeatedly, so that the patient feels uncomfortable, and the anus mucous membranes are easily damaged.

Therefore, there is a need to develop a device capable of maintaining the airtightness of the anus during the anoscope operation, which can inflate the air into the cavity to expand the intestinal canal during the operation, and can maintain the airtightness all the time during the operation of inserting, extracting or reciprocating the instrument.
