Embodiment Construction

[0009] Referring to the attached picture:

[0010] The biliary anastomosis stent of the present invention comprises a stent body 1 made of human body acceptable and degradable material. The stent body 1 is tubular and has a diameter suitable for being placed in the bile duct. The protrusion 2 of the purse string knot that fixes the stump of the bile duct.

[0011] The stent body 1 is made of human body acceptable and degradable material, such as polylactic acid. The diameter of the body 1 can be selected according to the thickness of the bile duct of the human body, and has various models.

[0012] During the anastomosis, purse-string sutures are first performed on the stumps of the bile ducts on both sides, and then the stents are put into the cavities of the bile ducts on both sides, and the purse-strings are tied on the inner sides of the protrusions 2 respectively, and the stumps of the bile ducts on both sides are fixed in the middle of the stent body 1, and The stumps ...

Abstract

Disclosed is a bile duct anastomosis stent, comprising a stent main body made of degradable material which is acceptable by people. The stent main body takes the shape of a tube and has a diameter which is suitable for putting in a bile duct. Each of the two sides of the outer surface of the main body is provided with a circle of protuberance for fixing the pouch line knots at the broken ends of the bile duct. The bile duct anastomosis stent has the advantages that the bile duct anastomosis stent is easy to operate, quick, short in anastomosis time and low in cost and has no complicating disease after the operation.

Description

(1) Technical field [0001] The invention relates to a bracket for bile duct anastomosis, which can simplify the bile duct anastomosis and improve the safety of the bile duct anastomosis. (2) Technical background [0002] At present, the one-stage repair after bile duct transection mainly adopts cholangioenterostomy, or T-tube drainage with end-to-end bile duct anastomosis. These two methods need to be sutured one by one with silk thread or absorbable thread, and the operation is cumbersome and the anastomosis takes a long time. Moreover, cholangioenterostomy will change the normal physiological channel, and postoperative complications such as bile reflux will occur. After end-to-end anastomosis of the bile duct and T-tube drainage, the T-tube needs to be left in place for a long time, which brings a lot of inconvenience to the life of the patient. In addition, the incidence of complications such as anastomotic leakage and anastomotic stenosis is higher after using these tw...
