Description

Hemorrhoidal ligation device for hemorrhoids excision}

The present invention relates to a hemorrhoid ligation device for hemorrhoid resection. More specifically, the present invention relates to a hemorrhoid ligation device for hemorrhoid resection. More specifically, the hemorrhoids formed in the anal canal are suctioned to the inside of the hemorrhoid suction section using suction force applied from the outside, and the base of the hemorrhoids is used to prevent blood flow from being supplied to the hemorrhoids. It relates to a hemorrhoid ligation device for hemorrhoid resection that ligates the hemorrhoids with an elastic band and allows the hemorrhoids to fall off naturally after a certain period of time, allowing the patient to relatively simply excise the hemorrhoids without being hospitalized for a long period of time.

Generally, hemorrhoids refer to swollen or inflamed vascular structures within the anal canal. When excessive pressure is applied to the structures made up of these blood vessels, the blood vessels become weakened and damaged, or blood flows in the wrong direction or becomes infarcted. As a result, the vascular structures become congested with blood, resulting in hemorrhoids.

In addition to the excessive pressure on the vascular structures mentioned above, some additional factors such as pregnancy, hard faeces, and straining may worsen the clinical condition such as pain and bleeding, and if left untreated in this condition, As the condition progresses, the hemorrhoids cushion becomes larger.

The above-mentioned hemorrhoids can be found in the form of internal hemorrhoids and external hemorrhoids, which are caused by expansion of the internal rectal venous plexus and form an anal canal at the level of the anorectal line. It occurs within the canal and is the result of an expansion of the external rectal venous plexus at the border of the anus.

Additionally, prolapse of hemorrhoids through the anus is thought to be caused by enlargement of the hemorrhoidal cushion and deterioration of the supporting connective tissue beneath the venous plexus, which consists of collagen fibers and fibroelastic tissue. This can cause a degenerative process to occur within it.

Meanwhile, treatment of hemorrhoids includes surgical treatment and non-surgical treatment, where surgical treatment involves surgically cutting the hemorrhoids. This procedure is effective for grade 3 or 4 prolapsed hemorrhoids, but requires a hospital stay and usually involves a long recovery time.

Non-surgical treatments include destroying hemorrhoidal tissue by shooting light, necrosis or atrophy of hemorrhoids using an anode current, freezing hemorrhoids with nitrous oxide or carbon dioxide, and excision of hemorrhoids using a laser, etc. or performing medical treatment on any of the following:

Although these non-surgical treatments are evaluated as less painful than surgical treatments, these treatments also cause pain to patients and are expensive, and in addition, despite procedures using these treatments, patients are unable to perform normal daily routines. There is a problem that it takes a long time to return to.

As a device related to the above-mentioned hemorrhoids treatment, Republic of Korea Patent Publication No. 10-2011-0111113 (name: hemorrhoidal artery ligation device for hemorrhoids treatment, hereinafter referred to as 'prior art') was proposed.

The prior art is a hemorrhoidal artery ligation device for treating hemorrhoids by performing hemorrhoidal artery ligation, comprising a hollow cylindrical probe having an open distal end, an open proximal end, and an outer wall with an internal hollow space; the outer wall includes an extension opening extending in the axial direction of the probe, the extension opening having a ligation window at a side extension thereof, the ligation window being open toward a distal end of the probe, the extension opening being disposed above the probe; an insertion sleeve comprising a wall in the form of a hollow cylinder with an opening and a rounded distal end for insertion into the patient's rectum, on which the probe is mounted, and rotating the probe about the axis of the hemorrhoidal artery ligation device with respect to the insertion sleeve; The gist of its technical structure is to include a wheel that gradually opens the extension opening of the probe from its distal end through the opening of the insertion sleeve by including a handle.

In the above-mentioned prior art, when trying to ligate hemorrhoids in the anal canal, 'after inserting the insertion sleeve into the rectum, insert the wheel equipped with the probe into the insertion sleeve, and slightly rotate the probe mounted on the wheel using the handle. The location of the hemorrhoidal artery is found using an ultrasound transducer, and when the location of the hemorrhoidal artery is detected, the curved needle is inserted into the inner hollow space of the wheel-shaped probe and the hemorrhoidal artery is ligated through the extension opening.

However, in the case of this prior art, the hemorrhoid artery is ligated to naturally excise the hemorrhoid, but the procedure is very complicated, and the base of the hemorrhoid artery is cut while the doctor inserts a curved needle into the hollow space inside the probu. There is a problem that it is very cumbersome to use because it must be ligated directly.

It consists of a ring portion 72 and a connecting piece 73 that holds the stopper portion 71 and the ring portion 72 from being separated from each other.

The operation of the present invention achieved in this way is as follows.

When attempting to ligate hemorrhoids 51 formed in the anal canal 50 using the hemorrhoid ligation device 10 for hemorrhoid resection according to the present invention, as shown in FIGS. 7 to 10, cleanly disinfect the area around the anus. Then, an anal dilator equipped with an anal diloscope equipped with an auxiliary light is inserted into the anal canal (50) to accurately confirm the location of the hemorrhoids (51) formed in the anal canal (50).

Then, the second suction pipe 41 protruding from the rear end of the cartridge body 40 constituting the hemorrhoid ligation device 10 according to the present invention is connected to the front end of the first suction pipe 25 at the front end of the main body 20. At the same time, the locking protrusion 47 protruding backward from the bottom of the rear end of the cartridge body 40 is fitted into the insertion groove 29 formed at the bottom of the front end of the main body to be coupled.

Then, remove the cover 70 covered with the hemorrhoid suction part 42 formed at the distal end of the second suction pipe 41, and push the pushers 33 installed on both sides of the main body forward to press the compression spring 30. When this compression is performed, the rear end of the compression spring 30 is caught on the inner end of the trigger 23, and the operating pin 31 fitted and coupled to the compression spring 30 moves to the outside of the front end of the main body 20. It protrudes.

The operating pin 31 protrudes outward from the tip of the main body 20 and simultaneously enters the inside of the transfer guide hole 44 on the cartridge body 40, and then the clamping piece formed at the tip of the operating pin 31 ( 31a) pinches the rear end of the connection bar 43 inserted into the transfer guide hole 44 and pushes it forward.

Then, insert the elastic band 45 on the outside of the tip of the hemorrhoid suction part 42, hang the connecting string 46 connected to the elastic band 45 to the tip of the connecting rod 43, and then apply external suction. The suction hose 27 connected to the pump is connected to the suction connector 26 protruding below the rear end of the handle 22 on the main body 20, and the suction pump is operated.

Then, while confirming the position of the hemorrhoids 51 in the anal canal 50 through the inside of the anal dilator inserted into the anus, the hemorrhoid suction part 42 protruding outside the tip of the cartridge body 40 is inserted into the anal canal 50. After insertion, the tip of the hemorrhoid suction part 42 is positioned accurately at the position of the hemorrhoids 51.

In this state, when the suction switch 28 installed on the lower outer side of the handle 22 on the main body 20 is turned to the “ON” state, the suction force generated by the operation of the suction pump is connected to the first suction pipe 25 and the first suction pipe 25. 2 As it is applied to the hemorrhoid suction part 42 through the suction pipe 41, the hemorrhoids 51 are sucked into the inside of the hemorrhoid suction part 42.

In this way, when the trigger (23) is pulled in a state where it is confirmed that the hemorrhoids (51) have been sucked into the hemorrhoid suction part (42) up to the base, the compression spring (30) hanging on the inner end of the trigger (23) is pulled. As soon as the locked state is released, it elastically returns to the rear, and at the same time, the operating pin 31 coupled with the connecting rod 43 also suddenly retreats to the inner rear of the main body 20.

At the same time, the elastic band 45 hanging on the outside of the tip of the hemorrhoid suction part 42 is separated due to the repulsive force of the connecting string 46 hanging on the tip of the connecting rod 43, which is momentarily pulled backward and released, causing hemorrhoids. The base of (51) is tightly ligated.

As blood flow is not supplied to the hemorrhoids 51 ligated by the elastic band 45 in this way, they naturally fall off after a certain period of time and the hemorrhoids are replaced.

In the process of ligation of the hemorrhoids 51 by the elastic band 45 as described above, the forward and backward movement of the connecting rod 43 is carried out through the guide slit 44a formed on the side of the transfer guide hole 44 and the side of the connecting rod 43. Since the formed guide piece (43a) is moved while being inserted, it is very stable. After the ligation of the hemorrhoids by the elastic band (45) is completed, the connecting string (46) connected to the elastic band (450) can be cut.

After the one-time hemorrhoid ligation procedure is completed in this way, the cartridge body 40 is separated from the main body 20 and discarded. At this time, the cartridge body 40 is inserted into the opening groove 60 formed in the upper part of the main body 20. When the rear part of the coupling piece 61 is pressed, the front part of the coupling piece 61 opens outward, and at the same time, the coupling piece 61 is inserted into and hung in the locking groove 41a formed on the outer side of the rear end of the second suction pipe 41. ) is released from the jammed state, and in this state, when the cartridge body (40) is pulled forward, the locking protrusion (47) is separated from the state where it was inserted in the insertion groove (29), and the entire cartridge body (40) is removed. is separated from the main body 20.
