Description
Technical Field
The invention relates to a medical instrument for removing rectal tumors, in particular to a magnetic ring anastomat for rectal tumor surgery.
Background
The rectal cancer is formed by malignant transformation of rectal tissue cells, the incidence rate of the rectal cancer is increased year by year along with improvement of life quality, the incidence rate of colorectal cancer (colon cancer + rectal cancer) is reported to be the third (the first two are lung cancer and gastric cancer), and the incidence rate of colorectal cancer may exceed the incidence rate of lung cancer and gastric cancer quickly and is the first. Therefore, research on the diagnosis and treatment of rectal cancer is a very important issue in the world today, and therapeutic means are also being developed. The application of the magnetic ring anastomat for the rectal tumor operation is a great leap of the surgical operation. To date, almost all gastrointestinal anastomoses can be anastomosed using staplers. Provides convenience for the operation, simplifies the operation, shortens the operation time, reduces the chances of tissue injury bleeding and operation infection, accelerates the recovery of the functions of tissues and organs, and shortens the hospitalization time. Provides necessary conditions for high-difficulty operations and the development of new operations and minimally invasive operations. The anastomotic part of the anastomat is mostly made of titanium nails, memory alloy, absorbable materials and the like, and the use of magnets as main materials is rare. All living things on earth, including human body, have certain magnetism and are always influenced by the geomagnetic field, a physical environmental factor, and the geomagnetic field becomes an indispensable environmental factor for living things to maintain normal life activities. China is the country for inventing the magnetite at the earliest time, and the compass is one of the four inventions. In 1990, the five Lang of Shannei Peng Han accidentally discovered that a child had intestinal obstruction due to a magnet patch therapeutic device for mispharynx attachment, and then the intestinal canal clamped by a magnet quickly and automatically formed sinus anastomosis, so that the magnet squeezing anastomosis of the intestinal tract and the biliary tract is created. Jansena et al, in 1981, utilized a polyester-coated magnetic ring to evert and anastomose the colon, and observed 7-12 days after the experiment on large animals that the magnetic ring penetrated the intestinal wall and was discharged with the intestinal peristalsis, the intestinal canal healed well, and the magnetic ring was used by 21 sigmoidectomy patients, and as a result, it was found that 2 of the patients had ruptured anastomotic stoma, 1 patient died from recurrent myocardial infarction 3 days after the operation, and the remaining 18 patients all healed well. In 2006, Muraoka in Japan developed a YMCA press type anastomat by utilizing the principle, which is applied to the treatment of biliary stricture after clinical living liver transplantation, and the anastomat can be completed by an endoscope and an interventional technology, so that the healing is good, the cost of a patient is low, and the pain is small. The magnetic ring promotes repair by using a magnetic field, can be discharged out of the body through the intestinal tract after penetrating tissues by using strong magnetic force, does not need additional incisions for anastomosis, and has important significance for improving and simplifying the intestinal tract anastomat. However, in the existing magnetic ring anastomat for the rectal tumor operation, in the aspect of a placing mechanism which can be smoothly placed into a human body, can be smoothly placed to a required position and can be smoothly taken out, the improvement is needed, and particularly, the improvement is needed in the operation which is completed only by placing the magnetic ring anastomat for the rectal tumor operation.
