The connection part 10 according to an embodiment is connected to the clip part 40 by passing through the guide part 20 and the inner side of the weight 30 in turn.

The weight of the weight 30 can be used to generate gravity to traction the lesion 70, and if necessary, the guide part 20 is also formed of a material that weighs a lot, so the lesion like the weight 30 It can generate gravity to pull (70). That is, the guide unit 20 and the weight 30 each have a set weight, and are characterized by pulling the lesion 70 by gravity.

In addition, since at least one of the guide unit 20 and the weight 30 has magnetism, traction may be performed by the pick-up tool 50 having magnetism. Both the guide portion 20 and the weight 30 may have magnetism, and various modifications may be implemented such as only the guide portion 20 having magnetism or only the weight 30 having magnetism.

The clip part 40 is located in a direction opposite to the wire 60 based on the guide part 20, is constricted by being caught by the weight 30, and is formed in various shapes within the technical idea of gripping the lesion 70. I can. The clip portion 40 according to an embodiment includes a locking hook portion 42 and a gripping portion 44.

In addition, the guide portion 20 and the weight 30 may be pulled by the pick-up tool 50 having a magnet moved into the body. At this time, the guide part 20 and the weight 30 are provided with magnetism, and the pick-up tool 50 having a rod shape also uses a permanent magnet or an electromagnet.

The clip-type traction device 1 using gravity according to the present invention aims at minimizing damage to the lower frontal layer when removing various types of lesions 70. Polyps are formed to facilitate removal of the lesion 70. Conventionally, an infusion solution is locally injected under the mucous membrane of the submucosal lesion 70 between the mucous layer and the muscle layer to create an artificial polyp.

In the case of making the full lip by the conventional method, chemical complications may occur because the submucosal layer is damaged more than necessary or drug chemicals such as physiological saline and epinephrine are used.

However, the clip-type traction device 1 using gravity according to the present invention does not need to make a hole in the inner wall to form a polyp, nor does it need to inject an injection liquid. Therefore, the present invention can reduce the occurrence of bleeding and perforation and complications caused by the capturing of the proximal muscle layer in the use of an incision or a snare.

In addition, the present invention minimizes damage to the submucosal layer in order to separate the lesion 70 of the lumen wall such as a mucosal tumor or adenoma from the muscle layer, while applying a physical force to the surface to pull the lesion 70 without swelling. Artificial flips can be created.

Hereinafter, an operating state of the clip-type traction device 1 using gravity according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

If the lesion 70 is not located on the upper side of the clip-type traction device 1 using gravity, the doctor must attempt to change the position of the patient. Non-sleep endoscopy does not matter in the change of position, but there is no difficulty in changing position because the patient is in a conscious state of sedation even if a sleep endoscopy is administered with a sleep inducing agent such as propofol or midazolam.

As shown in Fig. 6, the lesion 70 is positioned above the clip-type traction device 1 using gravity by body position transformation, and as shown in Fig. 7, the lesion 70 is applied to the gravity of the clip-type traction device 1 using gravity. Thereby, the lesion 70 extends downward. Since the position of the patient is changed in a direction in which the gravity of the clip-type traction device 1 using gravity is increased, the lesion 70 is pulled downward by the gravity of the weight 30.

On the other hand, as shown in Figs. 8 and 9, when the weight 30 or the guide unit 20 is made of a magnetic material, the connection unit 10 or the weight 30 is attached by using the pick-up tool 50 having a magnetism. Because of the traction, the physical force to traction the lesion 70 can be increased.

Therefore, even when performing a large adenoma of the large intestine over 10 cm, it is possible to focus on the resection, reduce bleeding, and reduce the procedure time. When the lesion 70 is separated from the mucosal layer in this way, the lesion 70 can be easily collected by physical or magnetic coupling without an inhalation device using the clip-type traction device 1 using gravity coupled to the separated lesion 70. have.

At this time, if you want to pull the lesion 70 further, or if you want to easily collect the removed lesion 70, the weight 30 is made of a magnetic material, and a pickup tool 50 composed of a permanent magnet or an electromagnet is made through a treatment hole of an endoscope. ) To work.

As described above, according to the present invention, the clip part 40 for gripping the lesion 70 and the weight 30 for generating gravity are connected, and in a state in which the clip part 40 grips the lesion 70 Since the lesion 70 is pulled by the gravity of the weight 30, the lesion 70 can be stably removed.

In addition, endoscopic removal of the lesion 70 occurring on the mucous membrane of the gastrointestinal tract wall can be easily and safely performed, and since it can be implemented by attaching only the weight 30 to the existing surgical clip, cost can be reduced. In addition, the endoscopy or laparoscopic operator can directly or auxiliaryly traction the mucous membrane or lesion 70 using only the weight of the weight 30.

In addition, compared to the traction method of the lesion 70 using the existing clip method, it is possible to minimize the radius and operation radius of the endoscope that must be moved for traction, and by utilizing the natural induction of position change, the procedure is performed without the use of additional treatment therapy or techniques. Can be made possible. In addition, the degree of traction of the clip part 40 can be varied according to the type of the weight 30, and the gravity can be adjusted by adopting weights 30 of various masses and shapes according to the type of the scalpel.

In addition, by using various weights of the weight 30, it can be used not only to remove the lesion 70, but also to traction the lesion 70 even when the perforation is sutured or when a limited field of view or positional restriction occurs. have. In addition, the clip-type traction device 1 using gravity can be used in both cases of using or not using clip suture, so that the perforation can be sutured with a clip less than the number of existing clips.

The present invention has been described with reference to the embodiments shown in the drawings, but these are only exemplary, and those of ordinary skill in the art will understand that various modifications and equivalent other embodiments are possible therefrom. will be.
