Problems solved by technology

After the current pancreaticogastric anastomosis or pancreaticojejunostomy, the stump of the pancreas lacks protection and is easily corroded by gastric juice or small intestinal juice. The stump of the pancreas is prone to massive bleeding, requiring reoperation, and even life-threatening

Embodiment Construction

[0029] see Figure 1 to Figure 7 Shown: Example 1: A protective sheath for the stump of the pancreas. The protective sheath is in the shape of a truncated cone and can cover the end of the pancreas after surgery. The inner end of the protective sheath 5 is closed 6. The protective sheath 5 The outer end of the protective cover 5 has an open shape 7. The protective cover 5 includes an inner cover 1 and an outer cover 2. The inner cover 1 is made of polypropylene material, and the outer cover 2 is made of polytetrafluoroethylene material.

[0030] The inner cover 2 and the outer cover 1 can be combined into one layer, the inner layer (inner cover) is the patch material polypropylene, and the outer layer (overcoat) is the polytetrafluoroethylene material widely used on the patch.

[0031] The contact surface of the abdominal viscera is made of polytetrafluoroethylene material, which has been widely used in clinical patches, which has good biocompatibility and avoids adhesion of t...

Abstract

A protective cover for the stump of the pancreas, the protective cover is in the shape of a truncated cone, the inner end of the protective cover is closed, and the outer end is open, the protective cover includes an inner cover and an outer cover, and the inner cover is made of polypropylene material Made, the jacket is made of polytetrafluoroethylene material. Or the material of the protective sheath is biomaterial decellularized small intestinal submucosal matrix or pig and bovine pericardium or bovine pericardium. The opening end of the protective cover is bent inwardly to have a folded edge, and a medical nylon rope is arranged inside the folded edge, and the medical nylon rope is drawn out from the folded edge, and the medical nylon rope is tightened so that the folded edge is tightened. The snare of the hem is tightened with a pre-knot similar to the hem for easy laparoscopic or da Vinci surgical pancreatic surgery application. The beneficial effect of the present invention is: it is simple in structure, convenient to use, and remarkable in effect, and can isolate the stump of pancreas from the environment of gastric cavity or intestinal cavity, and can effectively protect the stump of pancreas, thereby preventing the stump of pancreas from being damaged by gastric juice or intestinal juice. Corrosion, causing complications such as fatal hemorrhage.

Description

technical field [0001] The invention relates to the technical field of medical and surgical supplies, and belongs to a protective sleeve for the stump of the pancreas. Background technique [0002] Pancreaticoduodenectomy (PD) is the main method for the treatment of pancreatic head, lower end of common bile duct, duodenal papilla, and duodenal cancer. Generally, large medical institutions perform more than 200 cases of PD each year. PD surgery is complicated and there are many postoperative complications, among which pancreatic leakage (fistula) caused by pancreaticojejunal or pancreaticogastric anastomosis is the most common and serious. The danger of pancreatic leakage is that the pancreatic enzyme activated by bile-enteric juice leaks into the abdominal cavity, corrodes and digests the surrounding tissues, causes fatal hemorrhage or uncontrollable infection, and eventually leads to the death of the patient. Therefore, since the development of PD, surgeons have been explo...
