Multi-ring loop ligature apparatus

Abstract

The invention discloses a multi-ring loop ligature apparatus, which comprises a loop ligature cap, a loop ligature handle and a trigger line which is connected with the loop ligature cap and the loop ligature handle, wherein the top end of the trigger line is arranged at the periphery of the loop ligature cap and is provided with at least two junctions; an elastic ring for loop ligature is arranged between the two adjacent junctions; the trigger line comprises a first section and a second section which is connected in a detachable mode; and the first section is connected to the loop ligature cap, and the second section is connected to the loop ligature handle. According to the multi-ring loop ligature apparatus, when the loop ligature cap is needed to be replaced, the first section is separated from the second section, so that the second section is kept static and is not taken out of an esophagus to reduce the stimulation on stomachs of patients and improve the comfort level of the patients in the operation process; and simultaneously, the second section is not needed to pass through the esophagus repeatedly in the operation process to prevent dirt in the esophagus from being carried away in the operation process and improve the comfort level in the operation process. In addition, the sleeving process of the second section in the esophagus is reduced, and the operation efficiency can be improved, so that the operation process is safe and efficient.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a multi-ring ligation device. Background technique [0002] Esophageal variceal ligation is to inhale the varicose vein to be ligated into the ligation device through the endoscope, and use a rubber band to ligate the base of the varicose vein, thereby mechanically interrupting the blood flow of the diseased vein, causing the vein to shrink, and finally the varicose vein degenerates to achieve the abolition of the varicose vein. A procedure in which the vein falls off naturally. The multi-ring ligation device is currently the main surgical instrument for endoscopic ligation of esophageal varices. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a typical six-ring ligation device in the prior art. [0004] The multi-ring ligation device includes a ligation cap 11 with a pre-installed ligation ring 12 and an accompanying trigger wire 13; the m...

AI Technical Summary

Problems solved by technology

[0008] The ligation cap 11 of the above-mentioned multi-ring ligation device needs to use a wire guide 15 to connect the trigger wire 13 on the ligation cap 11 to the ligation handle 14 of the operating end through the endoscopic channel, and each time the ligation cap 11 is replaced, it needs to be carried out once. Lead wire operation, because a large number of patients’ digestive tract dirt will enter the endoscope cavity during the operation, and the lead wire will pass through the endoscope cavity, which will be contaminated with a lot of dirt. At the same time, because the gastroscope enters the esophagus, some patients will have an instinctive reaction , so that the dirt in the digestive tract increases, resulting in a dirty operation process, and the doctor's comfort during the operation is extremely poor

Moreover, every time the ligation cap 11 is replaced, a lead wire operation is required, which is unsafe and time-consuming
