Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically relates to a disposable internal hemorrhoid closer. Background Art

[0002] Internal hemorrhoids are divided into four stages. The third and fourth stages require surgical treatment. Currently, the following methods are commonly used for surgical treatment of internal hemorrhoids: 1. Internal hemorrhoid ligation: A surgical method in which the internal hemorrhoid is clamped and ligated at the base of the hemorrhoid nucleus with a silk thread to cause its necrosis and shedding. If there are more than 3 sites, it is likely to cause recent anal canal stenosis and difficulty in defecation, and there is no effect of lifting the anal cushion; 2. Internal hemorrhoid resection: The root of the internal hemorrhoid is clamped, and the hemorrhoid nucleus clamped above the curved hemostatic forceps is cut off with scissors. The mucosa is continuously sutured around the curved forceps with absorbable thread, and the suture is tightened and knotted while withdrawing the forceps to close the wound; or the root of the hemorrhoid nucleus is directly ligated with a No. 7 silk thread; if there are more than 3 sites, it is likely to cause recent anal canal stenosis and difficulty in defecation, and there is no effect of lifting the anal cushion; 3. External dissection and internal ligation of mixed hemorrhoids: The external hemorrhoid is incised and dissected upward to the dentate line, the base of the internal hemorrhoid is clamped and ligated at the base, and the internal and external hemorrhoids are completely removed. If there are more than 3 sites, it is likely to cause recent anal canal stenosis and difficulty in defecation, and there is no effect of lifting the anal cushion; 4. Internal hemorrhoid rubber band ligation: A surgical method in which an elastic thread or rubber band is put on the root of the internal hemorrhoid through an instrument; the incidence of bleeding due to the shedding of the elastic thread or rubber band is relatively high. If more than 3 internal hemorrhoids are ligated, it is likely to cause the shedding of the elastic thread or rubber band, recent anal canal stenosis and difficulty in defecation, and the effect of lifting the anal cushion is not good; 5. PPh surgery: Also called circular resection and stapling of rectal mucosa, using a PPH stapler to circularly resect 2-3 cm of the mucosa and submucosal tissue at the lower end of the rectum. The resection of the submucosal tissue blocks the blood supply of the superior hemorrhoidal artery to the hemorrhoid area. After the operation, the hemorrhoid body shrinks, and the effect of lifting the anal cushion is good, but the incidence of long-term anal canal stenosis is relatively high; 6. TST surgery: Partial resection and stapling of rectal mucosa, using a TST stapler to intermittently resect 2-3 cm of the mucosa and submucosal tissue at the lower end of the rectum. The resection of the submucosal tissue blocks the blood supply of the superior hemorrhoidal artery to the hemorrhoid area. After the operation, the hemorrhoid body shrinks. The purpose is to solve the problem of long-term anal canal stenosis after PPh surgery. The effect of lifting the anal cushion is inferior to that of PPh, and the incidence of postoperative bleeding is higher than that of PPh.

[0003] Some existing surgical methods lead to the problem of anal canal stenosis and difficulty in defecation, some surgical methods lead to an increase in the bleeding rate, and at the same time solve the problem that the effect of lifting the anal cushion of some methods is not good. Therefore, a disposable internal hemorrhoid closer is needed to improve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a disposable internal hemorrhoid closer to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A disposable internal hemorrhoid closer, comprising an operating handle. An installation cavity is formed inside the operating handle. An inner control handle is installed on the lower right side of the operating handle. A near protection box pull rope is installed on the upper side of the inner control handle. A far protection box pull rope is installed on the inner control handle and below the near protection box pull rope. A connecting shaft is installed on the inner control handle and between the near protection box pull rope and the far protection box pull rope. A outer control handle is installed on the lower side of the operating handle and on the left side of the inner control handle. A proximal block pull rope is installed on the upper side of the outer control handle. A distal block pull rope is installed on the outer control handle and below the proximal block pull rope. A protective tube is installed at the left end of the operating handle. A support frame is installed at the end of the protective tube. A far protection box is installed on the left side of the inner wall of the support frame. A far slider is installed inside the far protection box. A near protection box is installed on the right side inside the support frame. A near slider is installed inside the near protection box. A clip is arranged between the near protection box and the far protection box.

[0007] As a preferred solution of the present invention, the inner control handle is rotatably connected to the operating handle through a connecting shaft. A connecting shaft is installed on the outer control handle and between the proximal block pull rope and the distal block pull rope. The outer control handle is rotatably connected to the operating handle through a connecting shaft. Rubber anti-slip sleeves are installed on the lower outer walls of the inner control handle and the outer control handle by bonding.

[0008] As a preferred solution of the present invention, the near protection box pull rope and the far protection box pull rope are both connected to the inner control handle through hinges. The proximal block pull rope and the distal block pull rope are both connected to the outer control handle through hinges.

[0009] As a preferred solution of the present invention, the near protection box pull rope, the far protection box pull rope, the proximal block pull rope, and the distal block pull rope all pass through the protective tube and are respectively connected to the near protection box, the far protection box, the near slider, and the far slider.

[0010] As a preferred solution of the present invention, plate body sliding grooves adapted to them are formed at the front and rear sides of the inner wall of the support frame and at the connection parts with the near protection box and the far protection box. Slider sliding grooves are formed inside the near protection box and the far protection box.

[0011] As a preferred solution of the present invention, both the near slider and the far slider are arc-shaped, and the outer shapes of the near slider and the far slider are adapted to each other. The maximum distance between the near slider and the far slider is twice the diameter of the clip.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] In the present invention, the circular clip is used in cooperation with the far slider and the near slider arranged in an arc-shaped structure, so that the clip of the device can be changed into a closed crescent shape in the firing state, solving the problem that one end of the general clip is open and the bleeding rate is likely to increase. In addition, the arc shape solves the problem that both ends of the traditional clip are likely to hang the fibers in the intestine, resulting in the clip being easily detached and the bleeding rate increasing. The present invention intermittently clamps the internal hemorrhoids or the mucosa above the hemorrhoids perpendicular to the long axis of the rectum, and is not likely to damage the rectal muscular layer, and the tissue does not converge in the direction of the transverse axis of the rectum, so it will not cause long-term or short-term stenosis of the anal canal. Since the tissue converges in the direction of the long axis of the rectum, the purpose of lifting the anal cushion is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Please refer to Figures 1 - 4 , the present invention provides a technical solution:

[0024] A disposable internal hemorrhoid occluder, comprising an operating handle 1, an installation cavity 2 is provided inside the operating handle 1, an inner control handle 3 is installed on the lower right side of the operating handle 1, a near protection box pull rope 4 is installed on the upper side of the inner control handle 3, a far protection box pull rope 5 is installed on the inner control handle 3 and below the near protection box pull rope 4, a connecting shaft 6 is installed on the inner control handle 3 and between the near protection box pull rope 4 and the far protection box pull rope 5, an outer control handle 7 is installed on the lower side of the operating handle 1 and to the left of the inner control handle 3, a proximal block pull rope 8 is installed on the upper side of the outer control handle 7, a distal block pull rope 9 is installed on the outer control handle 7 and below the proximal block pull rope 8, a protective tube 10 is installed at the left end of the operating handle 1, a support frame 11 is installed at the end of the protective tube 10, a far protection box 12 is installed on the left side of the inner wall of the support frame 11, a far slider 13 is installed inside the far protection box 12, a near protection box 14 is installed on the right side inside the support frame 11, a near slider 15 is installed inside the near protection box 14, and a clip 101 is provided between the near protection box 14 and the far protection box 12.

[0025] Please refer to Figures 1 - 4, the inner control handle 3 is rotationally connected to the operating handle 1 through a connecting shaft 6. A connecting shaft 6 is installed on the outer control handle 7 and is located between the proximal block pull rope 8 and the distal block pull rope 9. The outer control handle 7 is rotationally connected to the operating handle 1 through the connecting shaft 6. Rubber anti-slip sleeves are installed on the lower outer walls of the inner control handle 3 and the outer control handle 7 by bonding. The near protection box pull rope 4 and the far protection box pull rope 5 are both connected to the inner control handle 3 through hinges. The proximal block pull rope 8 and the distal block pull rope 9 are both connected to the outer control handle 7 through hinges. The near protection box pull rope 4, the far protection box pull rope 5, the proximal block pull rope 8, and the distal block pull rope 9 all pass through the protection tube 10 and are respectively connected to the near protection box 14, the far protection box 12, the near slider 15, and the far slider 13. Plate body chutes 16 adapted to them are provided at the joints of the front and rear sides of the inner wall of the support frame 11 and the near protection box 14 and the far protection box 12. Slider sliding grooves 17 are provided inside the near protection box 14 and the far protection box 12. The near slider 15 and the far slider 13 are both arc-shaped, and the outer shapes of the near slider 15 and the far slider 13 are adapted to each other. The maximum distance between the near slider 15 and the far slider 13 is twice the diameter of the clip 101. By using the circular clip 101 in cooperation with the arc-shaped far slider 13 and near slider 15, the clip 101 can be changed into a closed crescent shape in the firing state of the device, solving the problem that one end of the general clip 101 is open and the bleeding rate is likely to increase. In addition, the arc shape solves the problem that the two ends of the traditional clip 101 are likely to hang the intestinal tract fibers, resulting in the easy detachment of the clip 101 and the increase of the bleeding rate. The present invention intermittently clamps the internal hemorrhoids or the mucosa above the hemorrhoids perpendicular to the long axis of the rectum, and it is not easy to damage the rectal muscle layer. Moreover, the tissue does not converge in the direction of the transverse axis of the rectum, so it will not cause long-term and short-term stenosis of the anal canal. Since the tissue converges in the direction of the long axis of the rectum, the purpose of lifting the anal cushion is achieved.

[0026] Workflow of the present invention: When in use, after the operator exposes the internal hemorrhoids and the mucosa above the hemorrhoids, place the support frame 11 of the device on the tissue to be clamped. Use a sharp-tipped hook to hook the tissue upward from the support frame 11. Then, successively pull the inner control handle 3 and the outer control handle 7, thereby driving the near protection box pull rope 4 and the far protection box pull rope 5 to move first, so as to drive the near protection box 14 and the far protection box 12 to move towards each other, release the hook, and then the proximal block pull rope 8 and the distal block pull rope 9 move. After that, the near slider 15 and the far slider 13 move towards each other, thereby squeezing the clip 101 until the clip 101 becomes a closed crescent shape. Then, use the hook to remove the tissue, and then reverse the outer control handle 7. At this time, the near slider 15 and the far slider 13 move away from each other. Then pull the inner control handle 3, and the inner control handle 3 drives the near protection box 14 and the far protection box 12 to move away from each other through the near protection box pull rope 4 and the far protection box pull rope 5. Remove the internal hemorrhoid occluder, check for no abnormalities, and the operation ends. By using the circular clip 101 in cooperation with the circular arc-shaped far slider 13 and near slider 15, the clip 101 of the device can become a closed crescent shape in the firing state, solving the problem that one end of the general clip 101 is open and the bleeding rate is increased. In addition, the circular arc shape solves the problem that the two ends of the traditional clip 101 are easy to hang the fibers in the intestine, resulting in the easy detachment of the clip 101 and the increase of the bleeding rate. The present invention intermittently clamps the internal hemorrhoids or the mucosa above the hemorrhoids perpendicular to the long axis of the rectum, and it is not easy to damage the rectal muscle layer. Moreover, the tissue does not converge in the direction of the transverse axis of the rectum, so it will not cause long-term and short-term stenosis of the anal canal. Since the tissue converges in the direction of the long axis of the rectum, the purpose of lifting the anal cushion is achieved.
