Description

Multi-side hole spiral bile duct plastic bracket

Technical Field

The utility model relates to the technical field of bile duct stents, in particular to a multi-side hole spiral type bile duct plastic stent.

Background

Retrograde Cholangiopancreatography (ERCP) via an endoscope is one of the main means for minimally invasive treatment of biliary-pancreatic diseases at present. On the basis of ERCP, can carry out interventional therapy such as bile duct lithotomy, bile duct stent implantation, endoscopic Nasal Bile Drainage (ENBD), etc., because ERCP operation does not need to be operated, the wound is little, and the hospitalization time is also shortened greatly, is welcomed by the patient.

The plastic support of the bile duct is needed in the implantation of the plastic support of the bile duct under the endoscope, the front end of the plastic support of the bile duct which is applied in clinic at present is not provided with a side hole, the plastic support is easy to be blocked after being implanted, so that the drainage of the bile is not smooth, and the general smooth time of the plastic support can be maintained for 2-3 months. Therefore, it is hoped to design a bile duct plastic bracket with a plurality of side holes at the front end to increase drainage effect, and solve the problems of short unobstructed period and easy blockage of the plastic bracket.

At present, the plastic brackets produced by different manufacturers are of the duodenum bending type, the central bending type and the double pig tail type. From the aspect of shape, the duodenum bending type and the central bending type are equivalent to a tube with bending angles, and the two designs are easy to shift a stent when the stent is used in a bile duct dilating case, so that the stent drainage fails. The double-pigtail type bile duct bracket is characterized in that two ends of the double-pigtail type bile duct bracket are provided with rings similar to the shape of a pigtail, and in the case of thinner bile duct, the double-pigtail type bile duct bracket is supported to the bile duct when the shape of the pigtail cannot be coiled into a bend or the bend is coiled in the bile duct, so that a patient has pain.

Therefore, a new bile duct plastic stent is needed to be applied to bile duct expansion and non-expansion surgery, so that the shifting risk and pain are reduced, and the drainage effect is improved.
