Abstract

1. TECHNICAL FIELD OF THE INVENTION

Medical field (digestive endoscopy treatment technology)

2. The technical problem to be solved by the invention

In the removal of varicose veins and polyps in the esophagus and gastrointestinal tract, it is removed from the surgical surgery to insert a noose through the tunnel of the endoscope to bind varicose veins, necrosis, dropping out and discharged to the body with feces.

3. Summary of Solution to Invention

A) Tighten the varicose veins tightly so that the supply of blood flow is inserted into the silicone tube so that the snare is not loosened after being tightened.

B) Cover the noose fitted with a thin vinyl tube on the outside of the guide tube so that the noose can be inserted through the endoscope tunnel into the gastrointestinal tract.

C) When the noose is inserted, it is installed at the end of the guide tube to pass through the endoscope tunnel, and after locking the varicose, etc., the locking device that can be installed and detached at the place where the guide tube and the noose meet to remain in the gastrointestinal tract.

4. Important uses of the invention

It is a non-invasive, low-invasive treatment device for varicose veins and tumors in the esophagus and gastrointestinal tract, tightening varicose veins with a lasso to block blood flow, necrosis and dropping out, and excrete into the stool, or tighten the bleeding part such as varicose veins with a hemostasis. This minimizes the pain of patients coming from treatment and shortens the recovery time, which serves to return to society quickly.

end. Purpose of the Invention

The present invention relates to a detachable medical ligation device, which is inserted into the esophagus or gastrointestinal tract through an endoscope tunnel, and binds tumors and varicose veins to block blood flow, thereby necrosing tumors and varicose veins and binds bleeding sites. .

Occlusion therapy using a conventional drug (a kind of medical adhesive) has a problem that thrombosis may be combined when a drug is directly injected into a blood vessel. In addition, the ligation method using rubber band has the disadvantage of repeating the insertion and removal of the endoscope one time in order to insert one rubber band, which causes a patient to require 4 to 8 ligations. Due to the nature of the patient has to endure the tremendous pain that comes from the repeated insertion and removal of the endoscope, the operator was a problem wasted time by repeating the hassle to find the lesion every endoscope. Therefore, the present invention was made by hooking with metal wire and polyethylene, and tightening and separating device in order to improve and supplement various conventional problems.

I. Composition and Function of the Invention

This will be described in detail with reference to the accompanying drawings.

The structure of the present invention is connected to the ligation machine (A) and the ligation tube is a guide tube (B) that allows insertion into the gastrointestinal tract through the hole of the endoscope. The ligation machine (A) is a snare type (4) made of stainless steel or plastic wire, and one end of the ligation machine (A) is made of a small circular ring (1). It is mounted on the female hook 9.

The noose (4) inserted into the gastrointestinal tract is covered with varicose veins and tightened with a silicone tube (3) to serve to necrosis the varicose veins.

Here, reference numeral (2) is a portion covered with a stainless metal tube and bonded to connect the thin wire and the thin wire. The guide tube (B) has a metal wire in the center connected to the one-hole handle (5) and its end is shaped like an L-shaped hook (9) so that the hook can be inserted into or slipped from the small circular ring (1) at the end of the hook. Allows for mounting and dismounting. Intermediate tube (7) is connected to the two-hole handle (6) has a structure that can be bent in the form of a metal wire wound in a spiral, it is a metal and can pass through the endoscope tunnel. When the two-hole handle (6) is pushed out of the one-hole handle (5), the L-shaped hook (9) comes out to the end of the metal tube, and the hook and the hook can be attached and detached, and the two-hole handle (6) is moved to the one-hole handle (5). Pulling toward), the metal tube 7 pushes the silicone tube 3 of the ligation machine A toward the noose 4 to tighten the noose. Pushing the outer vinyl tube 8 out of the handle covers the snare (4) portion of the mounted hook (A) to reduce the volume so that it can pass through the tunnel of the endoscope.

Effects of the present invention configured as described above are as follows.

The ligation device is attached to the L-shaped hook wire of the guide tube to reach the lesion site in the gastrointestinal tract through the tunnel of the endoscope. Ligation is performed by placing the ligation apparatus on the lesion tissue, and when the tissue is sufficiently ligated, the snare is separated from the hook wire to remove the guide tube, leaving only the snare in the gastrointestinal tract. Ligation lasso is eliminated as a result of necrosis of the ligation site within 1 to 2 weeks.

This will be described in more detail as follows. First hook the end ring of the noose to the L-shaped hook wire of the guide tube and pull the handle slightly to attach the noose to the guide tube. The outermost vinyl tube is then pushed out so that the noose enters the vinyl tube. In this state, it is inserted through the forceps of the endoscope to access the surrounding tumor and varicose veins (a). When the noose approaches the varicose veins to be ligated, pull the vinyl tube out of the vinyl tube so that it is well positioned around the varicose veins to be ligated (b) and slowly pull the handle to begin to tighten the noose and pull the handle all the way out. Make sure the snare is fully tightened (c). If the base of the varicose veins is completely ligated by the noose, the color of the varicose veins changes due to the blood flow blocking of the ligated varicose veins. The handle is then released again to allow the hook wire to slip out of the metal tube to separate the noose from the guide tube (d). With the endoscope intact, only the separated guide tube was taken out of the endoscope tunnel and the second ligation machine was connected again to repeat the insertion process. The procedure is completed by inserting the required amount of ligation and removing the guide tube and endoscope.

All. Effects of the Invention

As such, the present invention has a simple structure, which enables the treatment of tumors and varicose veins in the gastrointestinal tract without the need for surgical operation by inserting a single endoscope, thereby minimizing the pain of patients and significantly shortening the treatment time. It is for the return.
