Description

Technical Field

[0001] The invention relates to the field of medical instruments, and belongs to a hemorrhoid ligation stapler, and in particular to a detachable adsorption component and a controllable ligation stapler. Background Art

[0002] Hemorrhoid ligation is a common method for treating hemorrhoids, and has a good effect on general hemorrhoids. However, the hemorrhoid ligation currently used in clinical practice is usually performed by doctors under local anesthesia with the help of simple instruments. This simple instrument has only one specification and model, and uses a uniform size of ligation rubber ring. The ligation force of the ligation ring is constant. Since hemorrhoids vary in size, large hemorrhoids are less inhaled in the adsorption tube of uniform specifications, and the hemorrhoids are not ligated from the root, resulting in insufficient ligation. Small hemorrhoids are excessively inhaled in the adsorption tube of uniform specifications, and the normal tissue at the root of the hemorrhoids is inhaled, and the normal tissue is ligated, resulting in excessive ligation. The ligation force of the ligation ring is constant, and large hemorrhoids are not ligated to death, resulting in operation failure. Small hemorrhoids are overly tied, and the root tissue has not healed and the hemorrhoids fall off, which is easy to cause bleeding and pain. In case of severe hemorrhoid bleeding, emergency treatment is sometimes required under lumbar anesthesia or general anesthesia, which significantly increases the risk of surgery.

[0003] At present, there is another elastic wire ligation device, which relies on manual pulling to retract the tail end of the elastic wire so that the front end of the elastic wire is continuously tightened.
