Adjustable elastic-line ligation apparatus

Abstract

The invention relates to a medical apparatus, in particular to an adjustable elastic-line ligation apparatus. The adjustable elastic-line ligation apparatus comprises a gun body, a gun barrel and an elastic-line binding structure. The elastic-line binding structure is arranged in the gun body and comprises an elastic-line connection rod, an adsorption connection tube, a clamping connection part and a slide trigger. The elastic-line connection rod is connected with a pull line at the tail end of an elastic line; the adsorption connection tube is arranged in the gun body; the clamping connection part is used for connection of the elastic-line connection rod and the adsorption connection tube; the slide trigger is connected with the elastic-line connection rod; the elastic-line connection rod is provided with a projection portion, and the adsorption connection tube is provided with a convex block corresponding to the projection portion. Step action can be realized through a movable clamping fastener and a spring, the elastic line is tightened step by step by pulling of the slide trigger according to actual demands of a surgical process, the ligation force and speed can be controlled according to different patients or tissue conditions, surgical process acceleration is benefited, surgical time and mucosal tissue loss can be reduced, and a minimally invasive surgery effect is achieved.

Description

technical field [0001] The invention relates to a medical device, in particular to an adjustable elastic thread ligation device. Background technique [0002] Hemorrhoid ligation (also known as hemorrhoid rubber ring ligation, hemorrhoid suction ligation, etc.) is a common method for the treatment of hemorrhoids. etc.) ligated at the root (or base) of the internal hemorrhoid, thereby using the elastic retraction force of the rubber ring to block the blood supply of the hemorrhoid, causing it to necrosis, shrink, and fall off, thereby achieving the purpose of healing. In the past, the traditional instruments used for ligation surgery were extremely simple, time-consuming, laborious, and prone to complications. In order to change this situation, in the past ten years, there has been an automatic device that makes the ligation operation simple and easy, that is, the automatic hemorrhoid ligation device (also known as the continuous-fire hemorrhoid ligation device, the continuo...

AI Technical Summary

Problems solved by technology

The existing problem is that hemorrhoids that are more serious cannot be solved, and there is a lack of a tool that can efficiently and coordinate surgical actions, so as to improve the efficiency and success rate of the operation. The reason is that the positioning, adsorption and Actions such as ligation, in order to solve the above problems, the applicant previously applied for the Chinese patent No. CN105997182A in order to solve the above problems, but the structure is complicated, resulting in higher costs and treatment expenses
