Abstract

The invention discloses a loop ligature device under an endoscope. The loop ligature device under the endoscope comprises a loop ligature device body, a loop ligature device installation component anda loop ligature device releasing component, wherein the loop ligature device body is a rope belt with a locking structure; the loop ligature device installation component comprises a barrel and a loop ligature device fixing element, wherein the loop ligature device fixing element is used for fixing the loop ligature device body to the surface of the barrel; the loop ligature device releasing component comprises a traction element; the barrel is provided with a first end and a second end in an axial direction; compared with the second end, the first end is far away from the control end of thetraction element; the traction element is used for being connected with the loop ligature device body; and in addition, the traction element can drive the loop ligature device body to be retracted tothe center so as to be separated from the surface of the barrel. The loop ligature device under the endoscope adopts the rope belt with the locking structure, and therefore, a target object can be entangled.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an endoscopic ligation device. Background technique [0002] With the development of endoscopic technology, minimally invasive endoscopic surgery is available for early gastrointestinal tumors (such as early cancer and submucosal tumors), gastrointestinal bleeding, varicose veins, gastrointestinal fistula and diverticulum. A better therapeutic effect has been achieved, thereby avoiding traumatic surgery, and efficiently solving the patient's problems and even saving the patient's life. There are many methods of minimally invasive treatment of the above-mentioned diseases under the flexible endoscope. Among them, the ligation operation has unique advantages: the operation is simple and fast, and the operation time and intraoperative complications are greatly reduced. [0003] However, there are fewer types of instruments for realizing endoscopic ligation at present. ...
