Novel size-adjustable anal dilatation device for gastrointestinal surgery

Abstract

The invention discloses a novel size-adjustable anal dilatation device for the gastrointestinal surgery. The novel size-adjustable anal dilatation device comprises an anal dilatation device main body, a limiting ring and an observation cylinder. The anal dilatation device main body is arranged, an inflation air bag is arranged inside the anal dilatation device main body, an air inlet pipe is fixedly connected to the outer side of the anal dilatation device main body, an inflation mechanism is fixedly connected to one end of the air inlet pipe, and the other end of the air inlet pipe is arranged inside the anal dilatation device main body and fixedly connected to the outer side of the inflation air bag; and by the arrangement above, after the anal dilatation device main body is arranged in the anus, the inflation air bag in a dilatation body can be inflated by pressurizing the inflation mechanism, the inflation air bag drives an expansion ring to dilate the anus, a blocking ring can take a limiting effect on the inflation air bag so as to avoid deformation of the observation cylinder, and the inflatable air bag can be expanded according to the specific sizes of the anuses of different patients so as to achieve the size adjustable function. The device is simple in structure, convenient to use and high in applicability.

Description

Technical field [0001] The present invention belongs to the technical field of medical device, and in particular to a novel dimension of gastrointestinal surgery adjustable anhyd aus. Background technique [0002] The anus is also called anal tube expansion, refers to a method of expanding an anus with a finger or instrument, and is used for anal disease inspection, treatment and postoperative recovery. [0003] The existing anhydroe is in use, which is not convenient for the size of the size, which cannot be adapted to more patients, and the size of the patient has caused the pain, and the size is too small, which will lead to slipping, very good Convenient, and in use, often because of the speed of friction or expansion, it causes anal tear bleeding, seriously affecting the patient's experience, and is unable to observe and neglect internal observations and injustices in the anus. To this end, We propose a new type of gastrointestinal surgery to adjust the anus. Inventive cont...
