The present invention relates to a medical band ligation machine which is used to treat necrosis and treatment because a portion of a blood vessel is weakened and protrudes or the blood is ligated, so that the band is ligated into the lesion by inserting it into an endoscope of the body such as various water bumps. .

In general, when a portion of the blood vessel is weakened, such as the esophagus wall protrudes or the blood is bleeding, the bleeding occurs in this area is dangerous.

The treatment of the lesions was mainly performed by electrotherapy, laser, heat therapy by heat irradiation, or by pharmacotherapy with injection. However, these treatments had various problems such as damage or other effects to surrounding tissues of the lesions. .

For this reason, a medical band ligation machine has recently been used, which uses an endoscope to insert a band into the lesion site of the body, thereby ligation of blood vessels or bloody lesions. Necrosis is to treat only the lesions naturally.

This method has been used for the purpose of treating necrotic lesions such as blood vessels protruding or blood-colored lesions as well as tying lesions such as various water bumps of the body.

The conventional method will be described in more detail as follows.

A conventional endoscope having a flexible tube, a ligation machine coupled to the flexible tube tip of the endoscope and mounted with a plurality of bands on an outer circumference, and a plurality of bands coupled to the endoscope body and mounted on an outer circumference of the ligation machine It is composed of a controller that controls the ligation of the lesions by feeding them one by one.

In this case, the endoscope is provided with a plurality of channels, such as an illumination channel for supplying illumination to the tip of the tube, a suction channel for sucking air through the tube.

In addition, the ligation machine is configured to be connected to the controller through the inside of the ligation machine and the endoscope woven a plurality of bands mounted on the outer periphery.

Therefore, the device is guided to the front of the lesion site while observing the ligation by the endoscope, and the lesion site is sucked into the body of the ligation by suction operation through the suction channel of the endoscope.

In this state, the thread is drawn out by manipulating the controller, so that a plurality of bands mounted on the outer circumference of the ligation body are moved and supplied one by one, and the bands in the stretched state are reduced to bundle up to surround the lesion. The blood will not penetrate the area to treat the lesion by necrosis.

In addition, when the operation of tying the band to one lesion site is completed as described above, the operation of ligation of the lesion site is possible while continuously moving to another lesion site without drawing the endoscope. This is possible because the band is equipped with a plurality of bands and can be supplied and moved one by one.

In such a technique, a method of effectively moving and supplying a plurality of bands mounted to the outer periphery of the ligation body has been known in various forms.

First, US Patent No. 6,007,551 is configured to move the thread under a plurality of bands mounted to the outer periphery of the ligation machine to be connected to the outgoing wire through the endoscope, at least in front of the band between the plurality of bands It is provided with a thread of about the length to be supplied to the movement, and the rear end of the band is provided to be in close contact with the band by installing the locking beads in the thread respectively.

As the thread is pulled out, the latching ball pushes the first band to move forward. At this time, the first band is completely ligated between the first band and the second band because the length of the yarn is longer than the length of the first band being moved and supplied. The movement of the second band is limited until the movement is supplied from.

Therefore, as the thread is pulled out, only the first band on the ligation machine can be moved to be mounted on the lesion site, and the second and third bands can be sequentially moved and fed by continuously pulling out the thread.

However, the above-described configuration is not inconvenient to be equipped with a plurality of catching beads in the thread and pull out the band by the catching beads so that the catching of the beads may be separated from the thread as well as when the first band is completely drawn out. Up to the rest of the wire to limit the movement of the wire between the band to install the work was very inconvenient.

In particular, there was a problem that the supply of the band is not smoothly moved when the margin of the yarn between the bands is not appropriate or the locking beads of the thread fall.

In addition, U.S. Patent No. 5,398,844 is provided with a wire surrounding the band in a plurality of bands mounted on the outer circumference of the body of the ligation machine, respectively, and configured to be connected to the withdrawal wire through the endoscope.

This is to pull out each of the bands wound on the plurality of bands in turn one by one to support the band.

However, the above is a drawer by winding the thread in each of the plurality of bands, with the inconvenience of having to be equipped with a plurality of threads and a number of threads are tangled with each other, it is not possible to draw it or there is a risk of malfunction to draw out another thread first There was a problem.
On the other hand, in WO 97/45060 (Dec. 4, 1997) and U.S. Patent No. 5913865 (June 22, 1999), a plurality of circumferences are formed in the circumference with the through-holes and the tip of the cylindrical body coupled to the flexible tube tip of the endoscope. Forming a hooking groove, a plurality of bands are mounted to the outer surface of the body to zigzag the bottom and top of the band from the front to the back and back to the front in the state that the thread is supported by the hooking groove, the end through the endoscope It has been disclosed a technology for ligation of the lesion site by feeding the band on the body forward one by one while guiding to the outside.
However, the above technique is very inconvenient because the zigzag weaves the bottom and top of the band from the front to the back and back to the front while the body tip is supported by the locking groove by using a single wire.
Moreover, as the band is pulled out at one circumferential position, ie, the position at which the thread is bound as the thread is pulled out, it is difficult to uniformly supply the band as a whole, and thus it is very difficult to uniformly wrap and bind the lesion. There was this.

The present invention has been created to fundamentally solve all the problems of the prior art.

That is, the present invention has an object of maximizing reliability in use since the operation of supplying a plurality of bands one by one is provided effectively as the plurality of bands are simply and effectively woven together into one thread.

The object of the present invention, while ligating the lesion site while supplying the bands one by one forward by the operation to pull out the thread in the state of being woven with a plurality of band thread to the outer surface of the body coupled to the endoscope end, On the front end surface of the body, a plurality of engaging grooves are formed to face each other on the circumferential side,

The thread is configured in the form of a ring connecting both ends, one side of the thread is caught in the first left and right locking grooves, moving from the front to the rear under the first band and back to move forward from the back to the front band Unite,

The thread is moved from the rear to the front under the second band, and the left and right of the second band is moved from the rear to the front again from the rear to the front to wrap the end of the left and right engaging grooves and bind the second band. ,                         

The thread is moved from the rear to the front under the third band, and each of the left and right of the third band is moved from the rear to the front again from the rear to the front and wrapped, while the end is supported by the left and right locking grooves to bind the third band. Achieved by a ligation machine that binds multiple bands in the form.

Hereinafter, a preferred embodiment for achieving the above object of the present invention will be described in detail with reference to the accompanying drawings.

That is, the present invention, as shown in Figures 1 to 5,

Through holes 12 and the end of the cylindrical body 10 coupled to the front end of the flexible tube (3) of the endoscope (2) to form a plurality of engaging grooves on the circumference, the outer surface of the body (10) A plurality of bands are mounted to zigzag the bottom and top of the band from the front to the back and back to the front with the thread supported by the locking groove, and guide the end to the outside through the endoscope 2 to the controller 5 In winding the drum 6 of the controller 5 by rotating the drum 6 of the controller 5, the band on the body 10 is sequentially moved forward and supplied to draw the yarn, thereby ligating the lesion site. ,

Engaging grooves (a, b, c, d, e ...) (a ', b', c ', d', e '...) of the front end of the body 10 are formed opposite to the circumferential left and right and,

The seal 9 is formed in a ring shape connecting both ends, so that one side of the seal 9 is caught in the left and right first locking grooves (a) (a ') in front of the bottom of the first band 20. From the back to the back and back to the front to move forward wrap, bind the first band 20,

The seal 9 moves from the rear to the front under the second band 21, and the left and right ends of the left and right while moving and wrapping from the rear to the front again from the rear to the front above the second band 21, respectively. Supported by the grooves (b, c) (b ', c') and binds the second band 21,

The seal 9 moves from the rear to the front under the third band 22, and the left and right ends of the left and right hang while moving and wrapping from the rear to the front again from the rear to the front above the third band 22, respectively. Supported by the grooves (d, e) (d ', e') is made to bind a plurality of bands in the form of binding the third band (22).

At this time, it is preferable to mount the bands 20, 21, 22 ... in units of five or ten.

In addition, the outer surface between the left and right locking grooves of the body 10 is to form the groove portion 15 in the longitudinal direction to facilitate the operation of weaving the bands (20, 21, 22 ...) into the thread (9). .

In addition, the controller 5 of the present invention rotates in one direction by the one-way bearing 42 the drum 6, which winds the seal 9 connected directly to the drawing wire or directly on the base 40, as shown in FIG. 2. It is only possible to build up, the plurality of engaging grooves 43 of the same interval on the circumference of the drum (6) is formed so that the engaging ball 45 inserted into the groove 41 on the base 40 acts spontaneously It is configured to move and supply the bands on the body 10 one by one by the thread 9 which is inserted and installed by the rotation of the drum 6 so that the locking balls 45 are inserted into the locking grooves 43 in a rotational manner.

As an unexplained reference numeral 30 denotes a band guide for mounting the band.

Next will be described the operation of the present invention configured as described above.

First, look at the process of mounting a plurality of bands to the body 10, the ligation body 10 is coupled to the band guide 30 of the one side is conical.

In such a state, the bands 20, 21, and 22 through the band guide 30 elastically open while simply mounting to the outer surface of the ligation body 10.

As such, the bands 20, 21, 22..., Which are mounted to the outer surface of the body 10, are woven so that the ends thereof can be moved out one by one in order to the thread 9, which is tied in a ring shape.

In more detail, the first band 20 is mounted to the outer surface of the body 10. And one side of the thread (9) is left and right first locking groove (a) (a ') in a state of being caught under the first band 20 to move from the front to the rear, back from the rear to the front to wrap The first band 20 is bound.

At this time, when moving the seal 9 below the band 20, the bar (not shown) is inserted into the groove 15 on the body 10, and the seal 9 is easily moved in the state of lifting the band. You will be able to.

In the state in which the first band 20 is bound on the body 10 as described above, the second band 21 is mounted to the front of the first band 20 in the above-described manner on the body 10 again. .

At this time, the seal 9 is placed under the second band 21 so as to pass from the rear to the front.

In this state, the left and right sides of the seal 9 are moved from the rear to the front and back to the front of the second band 21, respectively, while the ends thereof are closed at the left and right locking grooves (b, c) (b ', c ') is supported and binds the second band 21.

Again, the third band 22 is mounted to the front of the second band 21 in the above-described manner on the body 10 in the state in which the second band 21 is bound as described above, wherein the seal 9 is Underneath the third band 22, the state is placed so as to pass from the rear to the front.

In this state, the left and right sides of the seal 9 are respectively moved from the rear to the front to the back from the rear to the front of the third band 22, and the ends thereof are left and right locking grooves (d, e) (d ', e). The third band 22 is bound and supported, but the method of binding the second and third bands 21 and 22 is the same, and the band is continuously attached to the band in this manner.

In this way, the outer periphery of the body 10 is used by mounting the band in units of five or ten.

In addition, in the process of mounting the band, the thread 9 is the leading locking groove (a, b, c, d, e ...) of the body (a ', b', c ', d', e '.. It does not have to be hung in order in.), And it is irrelevant even if it is hung in overlapping positions, but in this case, the thread may be entangled with each other.

On the other hand, when looking at the procedure using the ligation machine of the present invention as described above, the plurality of bands (20, 21, 22 ...) of the endoscope (2) of the body 10 is woven with a thread (9) To the end of the tube (3).

At this time, one side of the thread (9) woven with a plurality of bands is drawn out to the outside through the tube (3) to be connected to the drum (6) of the controller (5).

In this state, the front end of the body 10 is inserted into the lesion part 100 in front of the body using the endoscope 2, and the suction is performed by the endoscope 2, so that the blood vessel is protruding or a lesion such as water bumps. The portion is sucked into the through hole 12 of the body 10 as shown in FIG.

In this state, the handle 7 of the controller 5 is rotated.

That is, while the drum 6 rotates, the next locking groove 43 is inserted into the locking ball 45 to rotate one section to a position where the ball is supported.

As the drum 6 is rotated by one section, the thread 9 or the wire connected thereto is pulled up, and the yarn 9 is pulled by a predetermined length so that one band mounted on the body 10 at the most forward side ( 22) to be supplied by moving.

This is because the yarn 9 surrounds the band 22 so that the band 22 is moved forward and supplied by pulling the yarn 9 by a predetermined length.

At this time, the band 21 located at the rear of the band 22 does not move, which causes the seal 9 to move around and wrap the band 22 from the front to the back to the rear from the bottom to the back. The end is hung and supported by the locking grooves d and e (d 'and e'), and the part wrapping the band 22 is moved forward with the yarn as it pulls the thread 9, and then is supplied. The marginal length (L) of the seal 9 is secured so that the band 21 of the band 21 does not move, and the next band 21 does not move.

Since the length L of the thread 9 is not set arbitrarily by the user, the assembly 9 is easily secured while the thread 9 is naturally secured to the locking groove in the process of mounting the band as described above. Of course, the error can not occur even when installing the band.

In addition, since the present invention forms the seal (9) in the form of a ring connected to the end, the movement of the band 22 as described above is provided at the same time from the left and right of the body 10 to pull the band 22 from the left and right sides Since the effect occurs, the body 22 is able to move and supply the band 22 as a whole.

In other words, when the yarn 9 is simply carried out in one strand, only one portion of the band is pulled, so only the portion of the band is pulled at the time, so that the movement of the band is uncomfortable as well as being completely detached from the body 10. The problem of not being able to move supply also occurs, and the problem that the mounting process becomes more complicated when preventing and using a plurality of yarns is simply solved by constructing a ring form connecting the ends of the yarns.

As described above, the band 22 is completely displaced from the body 10 so that the band wraps around the lesion area 100 so that this part does not penetrate through blood and necrosis.

In addition, after treating the first lesion site 100 as described above, the endoscope 2 is continuously moved to another lesion site to repeat the treatment of the above-described process.

This is because the outer periphery of the body 10 is equipped with a plurality of bands, it is possible to move and supply them one by one as described above.

At this time, the handle 7 of the controller 5 is rotated as described above, but the rotation of the first section is again performed until the catch groove 43 of the drum 6 is inserted into the catching ball 45 and is elastically supported. Done.

Rotating the drum 9 or the wire connected thereto by rotating the section of the drum 6 as described above, pulls the seal 9 by a predetermined length so that another band 21 mounted forward on the body 10 is provided. If you move the) in order to ligation the lesion will be.

As the handle 7 of the controller 7 is rotated until the catch groove 43 of the drum 6 is supported to be inserted into the catch ball 45, the bands are supplied one by one, so that the lesion site is removed. Even if the naked eye does not check correctly, it will be able to perform exactly.

In addition, since the reverse rotation is prevented by the one-way bearing 42, the drum 6 is rotated as much as the drum 6 pulls out the seal 9, thereby preventing malfunction in advance.

As described above, in the present invention, a plurality of bands are moved one by one as we draw out the threads by simply and effectively weaving a plurality of bands mounted on the outer surface of the ligation body using one threaded ring-shaped end. As the drawer pulls the band from the left and right sides as the thread is drawn out, the moving supply is effectively provided as well as the bands are supplied one by one without error even when the operation of adjusting the margin of the thread is excluded, thereby improving reliability in use. It will have the effect of maximizing.
