Abstract

The utility model relates to a histocompatibility reinforced Y-shaped internal support for biliary tract portal areas. The internal support adopts a hollow Y-shaped pipeline structure, composed of a silica gel internal layer and a dacron external layer. The internal and external layers are adhered by means of special process. The internal layer is smooth, which is favorable for the bile to flow. The external layer is rough, which is favorable for sewing. The utility model has the advantages of simple structure, less pain of the patient, no blockage, no formation of calculus, and wide application to treatment of biliary tract diseases.

Description

The reinforced Y shape of biliary tract portal area histocompatibility inner support

This utility model provides a kind of reinforced Y shape of biliary tract portal area histocompatibility inner support that is used for the treatment of biliary tract.

At present, in operation on biliary tract, the most difficult is hepatic portal portal area cancer of biliary duct.Because the particularity of its growth site, can excision only occupy the minority can't have been excised when finding under most of situation, in can only doing, and the external drainage art.Use the rubber Y tube during external drainage, keep alimentation by the oral bile that drains after patient recovers to take food, very difficult and painful; Use the silica gel Y tube during interior drain, but be difficult for fixing with bile duct and surrounding tissue thereof and combine, very easily form leak, biliary peritonitis etc., patient can very fast death

The purpose of this utility model is: improve on the basis of present Y tube, change Y tube into double-decker, make internal layer effectively bile drainage go into intestinal, skin can be sewed up with bile duct and surrounding tissue, thus it is painful and patient's long period is survived to alleviate patient.

This utility model is achieved in that the reinforced Y shape of this biliary tract portal area histocompatibility inner support adopts Y shape double-skin duct structure.Internal layer adopts silica gel or other same type of material, and outer the employing washed wheel fabric or other same type of material, adopts special process bonding firmly between the ectonexine.Silica gel internal layer smooth surface helps the bile flow mistake; The dacron superficies are coarse, tough and tensile, can sew up with bile duct and surrounding tissue.Can place for a long time, not stop up, be difficult for forming calculus.

Advantage of the present utility model is: simple in structure, in conjunction with firm, alleviated patient misery, prolonged patient's life, can place and not stop up, be difficult for forming calculus for a long time.

Concrete structure of the present utility model is provided by following drawings and Examples:

In the accompanying drawing, Fig. 1 is the overall structure sketch map of the reinforced Y shape of this biliary tract portal area histocompatibility inner support, and Fig. 2, Fig. 3, Fig. 4 are respectively A-A, B-B, C-C profile.

In the accompanying drawings, [1] is internal layer, and [2] are outer.

This Y shape inner support adopts double-decker, includes internal layer [1] and outer [2] two parts.Internal layer [1] adopts silica gel material, also can adopt other same type of material.Outer [2] adopt the dacron material, also can adopt other same type of material.It is firm that internal layer [1] combines with outer [2].Internal layer [1] smooth surface helps the bile flow mistake; Outer [2] rough surface helps sewing up.

Claims

1, a kind of reinforced Y shape of biliary tract portal area histocompatibility inner support that is used for the treatment of biliary tract is hollow Y tube road structure, and it is characterized in that: this Y shape inner support is a double-decker, includes internal layer [1] and outer [2] two parts.

2, the reinforced Y shape of biliary tract portal area histocompatibility as claimed in claim 1 inner support is characterized in that: internal layer [1] adopts silica gel material.

3, the reinforced Y shape of biliary tract portal area histocompatibility as claimed in claim 1 inner support is characterized in that: outer [2] adopt the dacron material.
