Abstract

The invention discloses a magnet ring anastomotic surgical instrument which comprises a first magnet ring and a second magnet ring. Magnet ring anastomotic surgery is performed on a patient in a proctology department; an outer rigid piece and an inner rigid piece are arranged, and a first inflation piece, a second inflation piece and a third inflation piece form a mechanism for containing the first magnet ring and the second magnet, the characteristic that the inflation pieces occupy the space after being inflated and do not occupy the space after being deflated is utilized, the first inflation piece is provided with a first annular protrusion for positioning the first magnet ring, the second inflation piece is provided with a semispherical air bag for entering the anorectum successfully,and the third inflation piece is provided with a second annular protrusion for successfully separating the first magnet ring and the second magnet ring. The instrument has the advantages that according to the scheme, the instrument is simple in structure, reasonable in design and capable of being conveniently used for endoscopic mucosal resection of a patient suffering from hemorrhoids and low-position colorectal resection anastomosis; by adopting the inflation piece clamping mode, it is ensured that small damage and pain is caused during placement, and the instrument can also be quite conveniently taken out.

Description

technical field [0001] The invention relates to a rectal tumor resection medical instrument, in particular to a magnetic ring anastomosis surgical instrument. Background technique [0002] Rectal cancer is formed by the malignant transformation of rectal tissue cells. With the improvement of quality of life, the incidence of rectal cancer is increasing year by year. It has been reported that the incidence of colorectal cancer (colon cancer + rectal cancer) ranks third (the first two lung cancer and gastric cancer), the incidence of colorectal cancer may soon exceed the incidence of lung cancer and gastric cancer, ranking first. Therefore, research on the diagnosis and treatment of rectal cancer is a very important topic in the world today, and treatment methods are also developing. The application of magnetic ring anastomosis surgical instrument is a great leap forward in surgical operation. Today, almost all gastrointestinal anastomoses can be performed with staplers. It...
