Background

The hemorrhoid ligation (also called hemorrhoid rubber ring ligation, hemorrhoid suction ligation, etc.) is a common method for treating hemorrhoids, and has definite curative effect. The traditional instruments for performing the ligation operation are simple and crude, time-consuming and labor-consuming in operation and easy to cause complications. In order to change the situation, an automatic instrument which enables the ligation operation to become simple and easy, namely an automatic hemorrhoid ligation device (also called a continuous hemorrhoid ligation device, a continuous hemorrhoid ligator and the like) appears in the last decade. The advantages of using the instrument to carry out the ligation operation are that: the operation is simple, convenient, quick and accurate; the time is only 5-10 minutes; the probability of complications is low; patients generally do not need anesthesia, and pain is slight; most patients do not need to be hospitalized, and the treatment cost is low.

Hemorrhoid ligation devices currently fall into two categories: a rubber ring hemorrhoid ligation device and an elastic thread hemorrhoid ligation device.
