Description

Novel self-shedding bracket for common bile duct operation

Technical Field

The utility model relates to the field of medical appliances, in particular to a novel self-shedding bracket for common bile duct operation.

Background

In the common bile duct exploration operation, a bracket is required to be placed in the common bile duct, and the bracket is removed by gastroscopy operation after about one month after operation, so that the operation wound and the medical cost of a patient can be increased. There is a need for a self-shedding stent that can be used without subsequent stent removal procedures.

Disclosure of Invention

The utility model aims to provide a novel self-shedding bracket for common bile duct operation, which solves the problem of the common bile duct inner bracket removal operation in the background technology.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the novel self-shedding bracket for the common bile duct operation comprises a bracket tube 1, a soluble ring 2, a first barb 3 and a second barb 4, wherein the soluble ring 2 is arranged at one end part of the bracket tube 1, the first barb 3 is arranged on the soluble ring 2, and the second barb 4 is arranged at one end of the bracket tube 1 far away from the soluble ring 2; the soluble ring 2 is fixed at one end of the stent tube 1, the soluble ring 2 and the first barbs 3 are made of soluble materials, the stent can be prevented from sliding into the intestinal tract from the common bile duct in advance, the stent can be automatically fallen off after being dissolved and digested in one to two weeks in the body, and the second barbs 4 can prevent the stent from retrograde into the common bile duct. The length of the stent tube 1 is generally 8cm, 10cm and 12cm, and the diameter of the stent is generally 8Fr and 10Fr.

Preferably, the first barbs 3 are arranged on the soluble ring 2, the soluble ring 2 is arranged at one end of the stent tube 1, the direction of the first barbs 3 points to one end of the stent tube 1 without the soluble ring 2, the second barbs 4 are arranged at one end of the stent tube 1 far away from the soluble ring 2, the direction of the second barbs 4 points to one end of the stent tube 1 with the soluble ring 2, and the first barbs 3 and the second barbs 4 can prevent the whole stent from sliding to two ends.

Compared with the prior art, the utility model has the following beneficial effects:

the soluble ring is arranged at one end of the support tube, the first barbs are arranged on the soluble ring, and the soluble ring and the first barbs can be dissolved and digested after one to two weeks, so that the self-falling effect can be achieved.
