Endoscope tie gun and application method thereof

Abstract

The invention discloses an endoscope tie gun and an application method thereof, which can be applied in the medical field. A medical lashing band is utilized to bind disease carrier tissues. The gun body of the tie gun comprises a gun handle, a gun head and a long gun barrel which can penetrate into a disease carrier, wherein a similar T-shaped trigger structure is arranged in front of the gun handle of the gun body and is provided with a transverse transmission chute which can be matched with a raised line arranged on the long gun barrel of the gun body to realize transverse reciprocating dragging between the trigger structure and the gun body. The invention has the beneficial effect that the direct dragging transverse transmission is adopted between the gun handle of the endoscope tie gun and the trigger; the invention has the characteristics of reasonable design, simple structure, convenient operation, favorable binding effect and the like; a cutter can cut off a ribbon according to the practical used length, has reliable ligation effect and especially has better fastening and ligation effect on thicker ligation objects. Because of directly aiming at minimal invasion or endoscope operations, the invention has direct and obvious effect, solves the problem that binding grows out of nothing, saves operation time, further perfects minimal invasion idea and provides further guarantee for operation safety.

Description

technical field [0001] The present invention relates to a cable tie device, in particular to a medical cable tie gun and its use method—the method of use in minimally invasive medical operations. Background technique [0002] At present, it has always been the highest concept of surgeons to reduce surgical trauma and alleviate the pain caused by surgery to patients. "Minimally invasive" is a brand-new humanized and advanced surgical method inspired by the lofty concept of medicine in today's era of rapid medical development. It can be said that compared with conventional surgery in the past, minimally invasive surgery causes the least trauma to patients as much as possible. This trauma includes medical structure and psychology. Its characteristic is to achieve the same therapeutic purpose as conventional surgery with the help of advanced medical equipment through the smallest small orifice. Because minimally invasive surgery has less trauma, the patient suffers less pain, ...

Problems solved by technology

However, in current clinical minimally invasive surgery, when small tissues and organs such as blood vessels are ligated or ligated, the productized absorbable thread ligation ring with slipknot is usually used; for thicker tissues (such as gynecological laparoscope The cervical stump after the next total hysterectomy) generally uses absorbable thread to tie the slipknot outside the cavity, and then uses various knot pushers to push the knot in the cavity to further tighten the slipknot; according to the traditional surgical point of view, the effect of slipknot ligation is not good. Reliable, occult thread knot loosening may occur; at the same time, even if the thickest absorbable thread is used, its diameter is still very different from the thick tissue stump, which also violates the traditional surgical ligation "thread and tissue "diameter" ratio principle

At the same time, due to the structural reasons of various knot pushers, it is impossible to avoid friction on the ligation wire when pushing the slipknot, resulting in rough damage to varying degrees, and even directly wearing and tearing the ligation wire when the knot is pushed and tightened; on the one hand, it is hoped that It is possible to tighten the lashing thread, and on the one hand, it is necessary to avoid repeated pulling and wear. This contradiction may not be resolved

Moreover, since the intestinal canal, omentum, and other adjacent tissues and organs may be ligated by mistake during the operation, if a misoperation occurs, generally the ligation thread can only be cut off, which is too wasteful and ultimately What is important is that these all affect the convenience of the operation and the safety of the operation. Therefore, the invention of a new minimally invasive surgery strapping gun that improves the above-mentioned defects is imperative.
