Description

Multipurpose digestive endoscope working channel expansion sleeve

Technical Field

The utility model relates to the technical field of endoscopic surgery, in particular to a multipurpose type digestive endoscope working channel expansion sleeve.

Background

With the improvement of the manufacturing process of the electronic endoscope, under the condition that the diameter of the electronic endoscope is as small as possible, in order to meet the requirement that more surgical instruments enter, the working channel of the endoscope is as large as possible.

However, no matter how large the endoscope channel is, a common endoscope only has one working channel, and in some operation operations of gastroscopy, enteroscope and duodenoscope, a single working channel can not meet the operation requirements. For example, a double-channel endoscope is often needed in operation operations such as difficult foreign body extraction, ultrasonic inspection of a probe for diminishing upper digestive tract diseases, hemorrhage emergency treatment of digestive tract hemorrhage, purse string suture, ligation ring incision, ERCP double-guide wire technology, ERCP double-stent release and the like.

Although a double-channel gastroscope exists in the market at present, for example, Olympus GIF-2TQ260 is the double-channel gastroscope, the diameter of the gastroscope is about 11.7mm, and two working channels with the diameter of 3.2mm are arranged. However, the two-channel endoscope also has practical difficulties in clinical use because the two channels are close to each other, and if two instruments come out simultaneously without space and angle for operation, the two instruments are difficult to be freely controlled.

The double-channel endoscope has higher cost, and a plurality of hospitals are not equipped with the double-channel gastroscope conventionally. In addition, although a double-channel gastroscope exists, a double-channel enteroscope and a double-channel duodenoscope do not exist in clinic at present. Therefore, the utility model provides a multipurpose type digestive endoscope working channel expansion sleeve.
