Problems solved by technology

However, up to now, there is no clinically available stapler for hepatic biliary jejunum reconstruction. The main reason is that the location of high bile duct stenosis is high, the lesion is complicated, and the design of the stapler is extremely difficult.

Embodiment Construction

[0021] The present invention will be described in more detail below in conjunction with the accompanying drawings.

[0022] Such as figure 1 , figure 2 and image 3 As shown, the magnetic device for hepatobiliary jejunostomy and intestinal end-to-enter anastomosis consists of four sets of hepatic cholangiojejunal staplers and one pair of intestinal end-to-enteric staplers, and each pair of hepatic cholangiojejunal Anastomosis magnetic ring 1 and a hepatobiliary jejunum anastomosis magnet 2 with round flat blunt head and flat bottom matched with it are composed. There is a first longitudinal column 6 on the flat bottom surface, and a first through hole 7 is formed from the top of its round and flat blunt head to the bottom of the first longitudinal column 6. The width of the hepatobiliary jejunum anastomosis magnet 2 is smaller than the inner diameter of the corresponding bile duct stump 8, and the first longitudinal The outer diameter of the column 6 is smaller than the in...

Abstract

The invention relates to a hepaticojejunostomic and intestinal end-to-side anastomotic magnetic device consists of more than two sets of hepaticojejuno-anastomats and intestinal end-to-side anastomats. Each hepaticojejuno-anastomat consists of a hepaticojejunostomic magnetic ring and a hepaticojejunostomic magnet matched with the hepaticojejunostomic magnetic ring. The intestinal end-to-side anastomat consists of an intestinal end-to-side anastomotic magnetic ring and an intestinal end-to-side anastomotic magnet matched with the intestinal end-to-side anastomotic magnetic ring. Magnetic attraction of more than two sets of hepaticojejuno-anastomats and a set of intestinal end-to-side anastomat are used to complete wireless sutured hepaticojejunostomy and intestinal end-to-side anastomosis, thereby deficiencies of extremely high operation difficulty of traditional suturing way by needles and threads and postoperative complications, such as gallbladder drainage and stricture anastomotie stoma occurrence are avoided. And the hepaticojejuno-anastomats and intestinal end-to-side anastomat can be discharged from the body along with faeces in a period of time and are not left in the body, thereby no adverse effect is caused.

Description

technical field [0001] The invention relates to a medical device, in particular to a magnetic device for hepatic, bile duct and jejunal anastomosis and intestinal end-to-end anastomosis. Background technique [0002] High bile duct stenosis caused by various reasons is not uncommon in clinical practice. Due to the deep lesion and complex operation, after resection of the diseased tissue to reach the secondary hepatic bile duct, there are often as many as 4 to 8 bile duct stumps exposed in the operative field. Traditional hepatic duct plastic surgery and hepatic bile duct and jejunum suture anastomosis not only have extremely high requirements for the operator, are time-consuming and labor-intensive, but also often lead to high postoperative complications such as bile leakage and bile duct stenosis. Therefore, finding a convenient, feasible, and effective anastomosis method to improve the effect of hepatic cholangiojejunostomy is one of the clinical problems to be solved urge...
