Abstract

The invention discloses a magnetic anastomat applicable to bilioenteric anastomosis under a peritoneoscope. The magnetic anastomat comprises a magnetic anastomat body. The magnetic anastomat body comprises a magnetic anastomosis head and an anastomat matched with the magnetic anastomosis head for use. The magnetic anastomosis head can be replaced. The anastomat can be repeatedly used. The magnetic anastomosis head comprises a first magnetic ring body and a second magnetic ring body. The anastomat comprises an operation handle, an anastomat rod, a magnetic ring release device, an anastomat rod steering adjusting device and a thread adjusting device. According to the magnetic anastomat applicable to bilioenteric anastomosis under the peritoneoscope, minimally-invasive characteristics of the peritoneoscope technology and various advantages of the magnetic squeezing anastomosis technology are combined, and rapid and safe bilioenteric anastomosis under the peritoneoscope with no foreign matter residues at an anastomotic stoma can be achieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a magnetic stapler suitable for laparoscopic cholangioenterostomy. Background technique [0002] In many operations of hepatobiliary surgery, anastomosis of the bile duct and the small intestine is very important to restore the continuity of the digestive tract. The size of the abdominal incision brings different psychological pressures to the patients and affects the recovery and quality of life of the patients. Laparoscopic technique is a minimally invasive surgical technique, which avoids the disadvantages of large incisions in traditional hepatobiliary surgery, and is more in line with aesthetic requirements. However, at present, the laparoscopic choledochojejunostomy still adopts the traditional method (ie, suturing), which is a very difficult operation, and complications such as anastomotic leakage, anastomotic stenosis, and foreign body residues in the anastom...
