In general, the Endoloop is inserted into the human body and used for suturing the surgical site. It enables easy tissue resection and collection of secretions while observing the internal condition of the human body to discover diseases. And it is a medical device that helps a lot in diagnosis and treatment.

These endo loops have a long rod shape to facilitate insertion into the surgical site and are configured to expose the loop at the distal end.In order to treat diseases occurring in the chest cavity, abdominal cavity, or a specific part of the body, the intestines, blood vessels, or nervous system are cut and When performing a suturing procedure, the surgical site is sutured through a loop inserted into the human body.

Such an endo loop according to the prior art is made, for example, as in Korean Patent Registration No. 10-0603633.

Specifically, as shown in FIG. 1, the conventional endo loop 10 has a long rod shape in which a suture 14 is accommodated in a hollow insert rod 11 forming a main body and is made of a transparent plastic material.

In addition, the suture 14 has one end fixed to the rear end 13 of the insert rod 11 and the other end is a through hole formed in the front end 12 in a state accommodated in the insert rod 11 as shown. It is exposed to the outside through.

In addition, the suture 14 is prepared in the form of a loop through which the other end can bind the surgical site.

In the conventional endo loop 10 configured as described above, the front end is inserted through a small hole made in the skin so that the surgical site inside the human body can be accessed, and the surgical site is ligated using the loop of the suture 14, thereby completing the suture process. You can do it.

On the other hand, the endo loop 10 has a structure capable of tightening the loop by pulling the rear end of the suture 14 during the suturing process. In the conventional endo loop 10, the insert rod 11 A cutting groove 15 is formed to separate the rear end 13 from the. The cutting groove 15 has a cylindrical groove shape so that the rear end 13 of the insert rod 11 can be cut and separated at a specific position.

On the other hand, referring to FIG. 2, a surgeon who positions the front end 12 at the suture point in the human body applies force in the form of bending the insert rod 11 and the rear end 13 to force cutting from the insert rod 11. By separating the rear end 13 and pulling the suture fixed to the separated rear end 13, the loop of the suture 14 located at the surgical site is tightened, thereby performing a suture process.

In particular, in the case of performing appendectomy using such a conventional endo loop, the first endo loop is inserted through an incision formed in the human body to ligate the origin of the appendix to prevent the discharge of foreign matter from the large intestine, Subsequently, a second endo loop is inserted through the incision and ligated at a location spaced approximately 10 to 20 mm from the origin to the appendix to prevent discharging of foreign matter from the appendix side, and then cut between the two ligation sites with cautery scissors. Through the process of removing the appendix.

However, even in the case of highly skilled doctors, it is not easy to insert the loop of the endo loop into the appendix using a manipulator in the cramped abdominal cavity, and insert a plurality of endo loops and insert the loop into the appendix as described above. Since the procedure has to be performed several times, there is a problem that the operation time is delayed.

A perspective view showing a state in which a target tissue is ligated using an endo loop having a plurality of loops according to an embodiment.

3 to 5, the endo loop having a plurality of loops according to the present embodiment includes an insert rod 110, a pull tab 120, and a plurality of sutures 130.

The insert rod 110 is made of a transparent plastic material in the shape of an elongated rod that can be inserted into a surgical site inside the human body through a skin incision, and a plurality of sutures 130 can be inserted therein along the length direction. A through hole is formed.

The traction tab 120 is detachably connected to the rear end of the insert rod 110. This traction tab 120 may be configured integrally with the insert rod 110, in this case, a cutting groove (not shown) in a position to be separated so that the traction tab 120 can be easily cut from the insert rod 10. ) Is preferably formed.

A plurality of sutures 130 are provided, each suture 130 is inserted into the through hole of the insert rod 110, the rear end is fixed to the traction tab 120, and the front end is the insert rod 110 It is exposed to the front end side. A loop formed by a knot is formed at the distal end of the suture 130. The knot is formed so that the size of the loop can be easily reduced by the tensile force applied to the suture 130. Since the method of forming a knot in the suture 130 and the shape of the knot are known techniques in the field of laparoscopic surgery, a detailed description will be omitted. These sutures 130 are preferably made of biodegradable material that naturally degrades inside the human body after a certain period of time so that there is no need for surgery to remove the sutures 130 after laparoscopic surgery.

According to this embodiment, the plurality of sutures 130 are composed of a first suture 131, a second suture 132, and a third suture 133. Accordingly, the through hole formed inside the insert rod 110 is a first through hole 111a into which the first suture 131 is inserted, and a second through hole 111b into which the second suture 132 is inserted. And a third through hole 111c into which the third suture 133 is inserted, and the traction tab 120 connected to the rear end of the insert rod 110 is It consists of a first pull tab 121, a second pull tab 122 to which the rear end of the second suture 132 is fixed, and a third pull tab 123 to which the rear end of the third suture 133 is fixed.

In particular, the first loop (131a) provided at the tip of the first suture 131 prevents foreign matters from being discharged through the cut portion on the large intestine side by ligating the origin of the appendix. The second loop (132a) provided at the distal end secures a sufficient gap for cutting the appendix by ligating a position spaced approximately 10 to 20 mm from the origin of the appendix to the appendix side, and at the same time, from the cut portion on the appendix side. The third loop (133a) provided at the distal end of the third suture 133 prevents foreign matter from being discharged, and the region ligated by the first suture 131 is ligated once more, thereby stabilizing the ligation of the incision on the side of the large intestine. Can be secured.

To this end, a distance between the first through hole 111a and the second through hole 111b formed in the insert rod 110 is set to be approximately 10 to 20 mm apart, and the first through hole 111a ) And the third through hole 111c may be set to be spaced within 5mm. However, when the distance between the first through hole 111a, the second through hole 111b, and the third through hole 111c is set as described above, the diameter of the insert rod 110 increases.

Therefore, by obliquely arranging the tip of the second through hole 111b and the tip of the third through hole 111c, the distance between the first loop 131a, the second loop 132a, and the third loop 133a is reduced. The diameter of the insert rod 110 may be minimized by minimizing the gap between the first through hole 111a, the second through hole 111b, and the third through hole 111c while maintaining the above-described distance.

At this time, the distance between the first loop (131a) and the second loop (132a) should be set larger than the distance between the first loop (131a) and the third loop (133a). It is preferable that the inclination angle a1 of the second through hole 111b is set relatively larger than the inclination angle a2 of the third through hole 111c with respect to the first through hole 111a.

In addition, the first loop 131a of the first suture 131 and the third loop 133a of the third suture 133 are for ligating the origin of the appendix, that is, the cut on the large intestine side, and the second suture ( Since the second loop (132a) of 132 is for ligating the cut portion on the side of the appendix, the second pull tab 122 for pulling the second suture 132 is the first suture 131 and the third suture ( It is preferable that it is provided to be visually distinguished from the first pull tab 121 and the third pull tab 123 for pulling 133).

As an example, the second pull tab 122 to which the rear end of the second suture 132 is fixed is disposed inclined (b1) so as to intersect with the insert rod 110, and the rear end of the first suture 131 is The fixed first pull tab 121 is arranged in parallel with the insert rod 110, and the third pull tab 123 to which the rear end of the third suture 133 is fixed is inclined with respect to the insert rod 110 Can be placed. At this time, by setting the inclination angle b1 of the second pulling tab 122 to be different from the tilt angle b2 of the third pulling tab 123, the second pulling tab 122 becomes the first pulling tab 121 And the third pull tab 123, the first pull tab 121, and the third pull tab 123 are visually distinguished from each other.

On the other hand, although not shown in the drawing, the third pull tab 123 is arranged in parallel with the insert rod 110 so that only the second pull tab 122 is inclined, or the second pull tab 122 It may be possible to apply a colored coating layer on the surface so that the second pull tab 122 is visually distinguished.

In this way, when the second pull tab 122 is formed to be visually distinguished from the first pull tab 121 and the third pull tab 123, the operator may move the tip of the insert rod 110 to the surgical site through the incision. In the inserted state, it is possible to easily recognize a direction for inserting the third loop 133a, the first loop 131a, and the second loop 132a into the appendix in order.
