Automatic ligation device

Abstract

The invention provides an automatic ligator, comprising a wire-pull tube, a wire cutter, a wire-pull rod, a pull rod, a pull switch and a tractive magnet. The back end of the wire-pull tube is connected with the outer wall of the tractive magnet and the wall of the wire-pull tube is opposite to the armature of the tractive magnet. The wire cutter is fixed on the inner wall of the wire-pull tube by an elastic handle and the elastic handle is connected with the front end of a small steel wire. The armature of the tractive magnet is connected with the back end of the small steel wire. A wire hook is formed by the front end of the wire-pull rod, which is used for hanging the coils formed by one end of the ligature. The pull switch is connected between the wire-pull rod and the pull rod. The automatic ligator is in wire ligating type, so avoids the drawbacks existing in metal clip and can achieve ligation by single handle of the doctor. The automatic ligator has the advantages of small amount of ligature, low cost and lathy structure; therefore, the automatic ligator is suitable for ligating in deep and confined operation field.

Description

technical field [0001] The invention relates to a medical instrument for surgical operations, in particular to an automatic ligator. Background technique [0002] In surgery, ligation is one of the most basic operations, and knotting is the most basic action in various ligation operations. The traditional ligation process is as follows: one end of the ligature is held by a hemostat to bypass the tissue to be ligated, and the surgeon cuts the remaining ligature outside the knot after tying a surgical knot or triple knot with bare hands. When this type of ligation ligates the deep and fragile tissues, the ligated tissue is often torn due to improper force of the operator, especially beginners; When knotting, the first heavy knot is often loose; after the knot is finished, an assistant needs to cut the thread. Due to the experience of the assistant and other reasons, the length of the thread outside the knot is different. If it is too long, the foreign body reaction will be la...

Problems solved by technology

This method can prevent some patients from using metal devices such as titanium clips, but the wire sheath of this device needs to be transported through a tube, and the doctor needs to operate with both hands when tightening the wire sheath; additional instruments are needed to cut the wire, and the above operations are performed in a small space It is very cumbersome and requires the good cooperation of assistants, which will prolong the operation time; in addition, due to the long piping, a considerable length of ligature will be wasted, and the piping is disposable, resulting in relatively high product cost. High, expensive to use, affecting its popularity in clinic
