Preparation and Properties of Anastomat for Pancreaticoduodenectomy
摘要
Abstract
In order to effectively prevent the leakage of the pancreatic fluid during pancreaticoduodenectomy,this study took methyl vinyl silicone rubber as main material and prepares a pancreaticojejunostomy anastomat for clinical application.Through one step vulcanization molding with pre-embedded titanium nails,using silicone rubber as matrix,adding vulcanizing agent and reinforcing filling,etc.,the thermal property,mechanical property and chemical resistance property of the anastomat were analyzed.Results showed that when quality loss was 5%,the corresponding temperature of anastomat was 429.9℃.The breaking elongation rate and tensile strength decreased only 25.6% and 2.3% after enduring in 280℃ hot air for 6 h.The maximum quality loss was only 5.63% after soaking in the distilled water,3% dioxygen water,75% alcohol,hydrochloric acid (pH=0.8) and sadium hydroxide solution (pH=9) respectively.By using pancreaticojejunostomy anastomat,the fibrin hyperplasia between pancreas and intestinal wall will be promoted,normal blood circulation of duodenum and pancreas will also be enhanced,thus established the experimental basis for reducing operation difficulty,shortening surgery time and achieving high operative success rate.关键词
