Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an artificial anus control device. Background Technology

[0002] In recent years, the incidence of colorectal cancer has been increasing year by year, causing significant distress to health and lives. Low rectal cancer, in particular, where the tumor is less than 5-7 centimeters from the anal verge, often necessitates surgical removal of the anus along with the tumor to ensure the effectiveness of the procedure, greatly impacting patients' quality of life. Currently, the abdominoperineal resection (MILS procedure) for rectal cancer requires a colostomy in the abdominal wall to drain waste. However, many patients find this treatment difficult to accept. Firstly, the normal physiological and anatomical structure is artificially altered; secondly, the loss of excretory function in the lower body is psychologically difficult for patients to accept, increasing surgical pain. Furthermore, this treatment method has other drawbacks, such as less than ideal bowel control and strong odor.

[0003] In recent years, with the advancement of laparoscopic technology, many patients with rectal cancer located about 5 cm or even less from the anal verge hope to preserve their anus after surgery, but this affects the treatment outcome. Therefore, complete tumor resection remains a crucial part of treatment. During surgery, the anal sphincter must still be removed to ensure efficacy, leaving patients with either the loss of the anal sphincter or the loss of the anus post-surgery. Reconstructing anal function after resection remains a major challenge in rectal cancer treatment. The options are either to continue creating an abdominal incision or to pull down the bowel at the original anal site to reconstruct anal sphincter function. More and more doctors are exploring ways to reconstruct the anal sphincter or anal function. This invention is an attempt to use mechanical methods to replace the reconstruction of anal sphincter function.

[0004] Chinese patent application CN 103610518B discloses an artificial anus control device for enterostomy. This device closes the artificial anus by filling two elliptical balloons with a fluid medium to compress the middle section of the intestine. After the fluid medium in the two elliptical balloons is emptied, the compression of the intestine is released, allowing the intestine to defecate normally. However, this artificial anus control device requires the carrying of a fluid medium, and the balloons need to be filled with fluid medium each time it is used, which is very inconvenient, especially when traveling, as carrying the fluid medium is also inconvenient. In addition, when the two balloons of this artificial anus control device compress the intestine, there is point contact between the two elliptical balloons, rather than surface contact. The intestine is a hollow structure similar to a cylinder, and point contact cannot completely adhere to the inner wall of the intestine, thus failing to achieve effective control. Summary of the Invention

[0005] To address the aforementioned problems, this invention aims to provide an artificial anus control device that is both convenient to operate and provides effective control to prevent rectal necrosis.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An artificial anus control device includes a cannula, characterized in that: control components are movably connected to both the upper and lower ends of the inner wall of the cannula, and the two control components at the upper and lower ends of the cannula are arranged symmetrically from left to right; The control component includes a support rod fixed to the inner sidewall of the sleeve, a support cylinder fixed to the end of the support rod, the support cylinder being located at the center of the inside of the sleeve, and a first extrusion mechanism and a second extrusion mechanism being rotatably provided on the axial sidewall of the support cylinder, the first extrusion mechanism and the second extrusion mechanism being symmetrically arranged, and a pushing mechanism being provided between the first extrusion mechanism and the second extrusion mechanism. Each sleeve is provided with a drive component at a position corresponding to the control component, for driving the first extrusion mechanism and the second extrusion mechanism to rotate.

[0007] Furthermore, the drive assembly includes a first groove and a second groove formed on the sleeve, both the first groove and the second groove being arranged along the circumference of the sleeve, and the length of both the first groove and the second groove being 1 / 4 of the circumference; a first metal block is slidably disposed in the first groove, and a second metal block is slidably disposed in the second groove; A first connecting rod is fixedly provided on one side of the first metal block near the center of the sleeve, and a second connecting rod is fixedly provided on one side of the second metal block near the center of the sleeve. Both the first connecting rod and the second connecting rod are rotatably connected to the supporting cylinder.

[0008] Furthermore, a third electromagnet is provided at one end of the first slide and the second slide that are close to each other, a first electromagnet is provided at one end of the first slide that is away from the third electromagnet, and a second electromagnet is provided at one end of the second slide that is away from the third electromagnet.

[0009] Furthermore, a rotating groove is formed around the center of the supporting cylinder, and a first sector-shaped connecting plate is fixedly provided at one end of the first connecting rod near the supporting cylinder. A first rotating block matching the rotating groove is fixedly provided on the first sector-shaped connecting plate. A second sector-shaped connecting plate is fixedly provided at one end of the second connecting rod near the supporting cylinder, and a second rotating block that matches the rotating groove is fixedly provided on the second sector-shaped connecting plate.

[0010] Furthermore, the first extrusion mechanism includes a first rotating rod fixed on the first sector-shaped connecting plate. The first rotating rod is perpendicular to the first connecting rod, and a first arc-shaped extrusion plate is fixed at one end of the first rotating rod away from the first sector-shaped connecting plate. The first arc-shaped extrusion plate is coaxial with the center of the sleeve and extends along the axial direction of the sleeve.

[0011] Furthermore, the second extrusion mechanism includes a second rotating rod fixed on the second sector-shaped connecting plate. The second rotating rod is perpendicular to the second connecting rod, and a second arc-shaped extrusion plate is fixed at one end of the second rotating rod away from the second sector-shaped connecting plate. The second arc-shaped extrusion plate is coaxial with the center of the sleeve and extends along the axial direction of the sleeve. The second arc-shaped extrusion plate is symmetrically arranged with the first arc-shaped extrusion plate.

[0012] Furthermore, the pushing mechanism includes an elastic band fixed to the surface of the first arc-shaped extrusion plate and the second arc-shaped extrusion plate. A telescopic rod is fixed on the side of the support cylinder opposite to the support rod. The first rotating rod and the second rotating rod are respectively provided with a first mounting groove and a second mounting groove that match the telescopic rod on their respective sides. The end of the telescopic rod is fixedly connected to the center of the elastic band.

[0013] Furthermore, a clearance groove is provided at one end of the support rod near the support cylinder, and the top and bottom of the clearance groove are fixedly connected to the top and bottom surfaces of the support cylinder, respectively.

[0014] Furthermore, a silicone layer is fixedly sleeved on the outside of the sleeve, and the outer wall of the silicone layer has a corrugated structure.

[0015] The beneficial effects of this invention are: compared with the prior art, the improvement of this invention lies in that... 1. The artificial anus control device of this invention uses two control components located at the top and bottom of the cannula to squeeze the upper and lower ends of the rectum. It does not directly compress the end of the rectum. When the two control components squeeze the upper and lower ends of the rectum, they apply force in a staggered manner, so that the middle part of the rectum is sealed, thereby ensuring that the patient's excrement will not leak out. At the same time, the upper end of the rectum is only subjected to force from the right side, and the blood in the mesentery can flow down from the left side of the upper end of the rectum due to the body's regulation. The middle part of the rectum is not subjected to force, and the blood in the mesentery can flow normally. The lower end of the rectum is only subjected to force from the left side, and the blood in the mesentery can flow down from the right side of the lower end of the rectum due to the body's regulation. Therefore, it will not cause rectal necrosis.

[0016] 2. The artificial anus control device of the present invention compresses the rectum with a first arc-shaped compression plate and a second arc-shaped compression plate, causing the inner wall of the rectum to adhere and form a closed segment. When the first arc-shaped compression plate and the second arc-shaped plate are closed, they form a complete arc-shaped structure. Both the first arc-shaped compression plate and the second arc-shaped compression plate extend along the axial direction of the sleeve, so that the contact compression between them and the rectum is a surface contact, which improves the control effect compared with point contact.

[0017] 3. The artificial anus control device of the present invention is further provided with a pushing mechanism between the first arc-shaped compression plate and the second arc-shaped compression plate. The elastic band in the pushing mechanism can deform along the opening of the first and second arc-shaped compression plates, and at the same time, it is pulled towards the center of the sleeve under the action of the telescopic rod. The space between the elastic band and the inner wall of the sleeve is the space where the rectum returns to its normal shape, which can ensure the excretory function of the rectum. At the same time, when the first and second arc-shaped compression plates rotate towards each other to form a closed structure, the elastic band deforms with the rotation of the first and second arc-shaped compression plates. With the action of the telescopic rod, it can push the rectal tissue, preventing the rectal tissue from being trapped between the first and second rotating rods. This can protect the rectal tissue, improve the control effect, and prevent the leakage of excrement.

[0018] 4. The artificial anus control device of the present invention only requires control of the first electromagnet, the second electromagnet, the third electromagnet and the telescopic rod during use. The first electromagnet, the second electromagnet, the third electromagnet and the telescopic rod can all be controlled externally by a controller, which is convenient for patients to use when they go out, without the need to carry other auxiliary equipment. In addition, it is lightweight and reduces the discomfort of patients. Attached Figure Description

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] See attached document Figure 1-10The artificial anus control device shown includes a cannula 1, which is a cylindrical structure with openings at both ends. The inner diameter of the cannula 1 matches the rectum 24, specifically, the patient's rectum 24 can be located inside the cannula 1. A silicone layer 23 is fixedly sleeved on the outside of the cannula 1. The silicone layer 23 is made of medical soft silicone gel or other materials that will not cause rejection in the human body (refer to existing prosthetic materials). It can be directly fixed to the patient's pelvic floor muscles by suturing without causing rejection. The outer wall of the silicone layer 23 has a corrugated structure to facilitate matching with the shape of the patient's pelvic floor muscles.

[0034] Control components are movably connected to both the upper and lower ends of the inner wall of the sleeve 1, and the two control components at the upper and lower ends of the sleeve 1 are symmetrically arranged, as shown in the attached figure. Figure 1 As shown, the control component at the upper end of the cannula 1 is located on the right side of the inner wall of the cannula 1, which can compress the right side of the top of the rectum 24. The control component at the lower end of the cannula 1 is located on the left side of the inner wall of the cannula 1, which can compress the left side of the bottom of the rectum 24. When the two control components compress the rectum 24, the rectum 24 forms an S-shaped structure, and the middle part of the rectum 24 is closed. This ensures that the patient's excrement does not leak out under normal circumstances. At the same time, the upper end of the rectum 24 is only subjected to the force on the right side. Due to the body's regulation, the blood in the mesentery can flow down from the left side of the upper end of the rectum 24, while the middle part of the rectum 24 is not subjected to force, and the blood in the mesentery can flow normally. The lower end of the rectum 24 is only subjected to the force on the left side, and the blood in the mesentery can flow down from the right side of the lower end of the rectum 24 due to the body's regulation. Therefore, it will not cause necrosis of the rectum 24.

[0035] Specifically, the control component includes a support rod 2 fixed to the inner wall of the sleeve 1, a support cylinder 3 fixed to the end of the support rod 2, the support cylinder 3 being located at the center of the sleeve 1, and a first extrusion mechanism and a second extrusion mechanism being rotatably mounted on the axial side wall of the support cylinder 3. The first extrusion mechanism and the second extrusion mechanism are symmetrically arranged front and rear, and a pushing mechanism is provided between the first extrusion mechanism and the second extrusion mechanism. A drive component for driving the first extrusion mechanism and the second extrusion mechanism to rotate is provided at a position on the sleeve 1 corresponding to the control component.

[0036] The driving assembly includes a first groove 4 and a second groove 5 formed on the sleeve 1. Both the first groove 4 and the second groove 5 are arranged circumferentially along the sleeve 1, and the length of both the first groove 4 and the second groove 5 is 1 / 4 of the circumference. A third electromagnet 8 is provided at one end of the first groove 4 and the second groove 5 that are close to each other. A first electromagnet 6 is provided at one end of the first groove 4 that is away from the third electromagnet 8. A second electromagnet 7 is provided at one end of the second groove 5 that is away from the third electromagnet 8. A first metal block 401 is slidably disposed in the first groove 4, and a second metal block 501 is slidably disposed in the second groove 5. A first connecting rod 9 is fixedly disposed on one side of the first metal block 401 near the center of the sleeve 1, and a second connecting rod 10 is fixedly disposed on one side of the second metal block 501 near the center of the sleeve 1. Both the first connecting rod 9 and the second connecting rod 10 are rotatably connected to the supporting cylinder 3. It should be noted that the sleeve 1 can be made of medical-grade titanium. Insulation treatment is required on the sidewalls of the first slide 4 and the second slide 5 to prevent the first electromagnet 6, the second electromagnet 7, and the third electromagnet 8 from exerting a magnetic force on the sleeve 1 when energized. When the first electromagnet 6 and the second electromagnet 7 are energized, they attract the corresponding first metal block 401 and second metal block 501 under magnetic force, causing them to slide within the corresponding first slide 4 and second slide 5. This drives the first connecting rod 9 and the second connecting rod 10 to rotate. During rotation, the ends of the first connecting rod 9 and the second connecting rod 10 always rotate around the supporting cylinder 3. Simultaneously, the first connecting rod 9, the second connecting rod 10, and the supporting rod 2 support the supporting cylinder 3, improving its stability. When the first electromagnet 6 and the second electromagnet 7 are de-energized, the third electromagnet 8 is energized, causing the first metal block 401 and the second metal block 501 to rotate in opposite directions, driving the first connecting rod 9 and the second connecting rod 10 to rotate synchronously in opposite directions.

[0037] The support rod 2 has a relief groove 201 at one end near the support cylinder 3. The top and bottom of the relief groove 201 are fixedly connected to the top and bottom surfaces of the support cylinder 3, respectively, to support and fix the support cylinder 3. The relief groove 201 can prevent the first connecting rod 9 and the second connecting rod 10 from being blocked during rotation.

[0038] A rotating groove 301 is formed around the middle of the supporting cylinder 3. A first sector-shaped connecting plate 11 is fixedly provided at one end of the first connecting rod 9 near the supporting cylinder 3. A first rotating block 12 that matches the rotating groove 301 is fixedly provided on the first sector-shaped connecting plate 11. The rotation of the first sector-shaped connecting plate 11 and the first connecting rod 9 can be realized through the cooperation of the first rotating block 12 and the rotating groove 301. A second sector-shaped connecting plate 13 is fixedly provided at one end of the second connecting rod 10 near the supporting cylinder 3. A second rotating block 14 matching the rotating groove 301 is fixedly provided on the second sector-shaped connecting plate 13. The rotation of the second sector-shaped connecting plate 13 and the second connecting rod 10 can be realized through the mutual cooperation between the second rotating block 14 and the rotating groove 301.

[0039] The first extrusion mechanism includes a first rotating rod 15 fixed on the first sector-shaped connecting plate 11. The function of the first sector-shaped connecting plate 11 is to connect the first connecting rod 9 and the first rotating rod 15. The first rotating rod 15 is perpendicular to the first connecting rod 9, and a first arc-shaped extrusion plate 16 is fixed at one end of the first rotating rod 15 away from the first sector-shaped connecting plate 11. The first arc-shaped extrusion plate 16 is coaxial with the center of the sleeve 1, and the first arc-shaped extrusion plate 16 extends along the axial direction of the sleeve 1.

[0040] The second extrusion mechanism includes a second rotating rod 17 fixed on the second sector-shaped connecting plate 13. The function of the second sector-shaped connecting plate 13 is to connect the second connecting rod 10 and the second rotating rod 17. The second rotating rod 17 is perpendicular to the second connecting rod 10, and a second arc-shaped extrusion plate 18 is fixed at one end of the second rotating rod 17 away from the second sector-shaped connecting plate 13. The second arc-shaped extrusion plate 18 is coaxial with the center of the sleeve 1 and extends along the axial direction of the sleeve 1. The second arc-shaped extrusion plate 18 is symmetrically arranged with the first arc-shaped extrusion plate 16.

[0041] The pushing mechanism includes an elastic band 19 fixed to the surface of the first arc-shaped extrusion plate 16 and the second arc-shaped extrusion plate 18. The elastic band 19 can stretch or contract as the first arc-shaped extrusion plate 16 and the second arc-shaped extrusion plate 18 rotate. A telescopic rod 20 is fixed on the side of the supporting cylinder 3 opposite to the supporting rod 2. The first rotating rod 15 and the second rotating rod 17 are respectively provided with a first mounting groove 21 and a second mounting groove 22 that match the telescopic rod 20. The end of the telescopic rod 20 is fixedly connected to the center of the elastic band 19. When the first arc-shaped extrusion plate 16 and the second arc-shaped extrusion plate 18 rotate to the open state of the control component, the elastic band 19 is stretched. At this time, the telescopic rod 20 contracts, pulling the center of the elastic band 19 closer to the center of the sleeve 1, thereby forming a large gap between the elastic band 19 and the inner wall of the sleeve 1, so that the rectum 24 is in the open state. When the first arc-shaped squeezing plate 16 and the second arc-shaped squeezing plate 18 rotate in opposite directions to close the control assembly, the elastic band 19 undergoes a restorative change, and at the same time, the telescopic rod 20 extends, so that the elastic band 19 is consistent with the outer wall shape of the first arc-shaped squeezing plate 16 and the second arc-shaped squeezing plate 18. The elastic band 19 will not be trapped between the first rotating rod 15 and the second rotating rod 17, and at the same time, it can push the rectal tissue 24 to avoid the rectal part being trapped between the first rotating rod 15 and the second rotating rod 17.

[0042] Working principle of the invention: In use, the silicone layer 23 of the artificial anus control device is sutured and fixed to the patient's pelvic floor muscles. The patient's rectum 24 is inserted into the cannula 1 and placed in the gap between the first rotating rod 15, the second rotating rod 17, and the elastic band 19. The first electromagnet 6 and the second electromagnet 7 are energized, attracting the corresponding first metal block 401 and second metal block 501 under magnetic force. This causes the first metal block 401 and second metal block 501 to slide within the corresponding first sliding groove 4 and second sliding groove 5, thereby driving the first connecting rod 9 and the second connecting rod 10 to rotate. As the first connecting rod 9 and the second connecting rod 10 rotate, they drive the first sector-shaped connecting plate 11 and the second sector-shaped connecting plate 13 to rotate. The first arc-shaped compression plate 16 and the second arc-shaped compression plate 18 rotate and close, causing the elastic band 19 to recover its elasticity. Simultaneously, the telescopic rod 20 is extended, causing the elastic band 19 to close with the first arc-shaped compression plate 16. The outer wall morphology of the curved compression plate 16 and the second arc-shaped compression plate 18 is consistent, and the elastic band 19 will not be clamped between the first rotating rod 15 and the second rotating rod 17. At the same time, it can push the rectal tissue 24. When the first rotating rod 15 and the second rotating rod 17 are closed, the rectum 24 is squeezed between the first arc-shaped compression plate 16, the second arc-shaped plate 18 and the inner wall of the cannula 1, so that the rectum 24 is closed. The control component at the upper end of the cannula 1 squeezes the right side of the top of the rectum 24, and the control component at the lower end of the cannula 1 squeezes the left side of the bottom of the rectum 24. When the two control components squeeze the rectum 24, the rectum 24 forms an S-shaped structure, as shown in the attached figure. Figure 11 As shown, the middle part of the rectum 24 is closed, which ensures that the patient's excrement does not leak out under normal circumstances. At the same time, the upper end of the rectum 24 is only subjected to force from the right side. Due to the body's regulation, the blood in the mesentery can flow down from the left side of the upper end of the rectum 24, while the middle part of the rectum 24 is not subjected to force, and the blood in the mesentery can flow normally. The lower end of the rectum 24 is only subjected to force from the left side, and the blood in the mesentery can flow down from the right side of the lower end of the rectum 24 due to the body's regulation. Therefore, it will not cause necrosis of the rectum 24.

[0043] When the patient needs to defecate, the first electromagnet 6 and the second electromagnet 7 are de-energized while the third electromagnet 8 is energized. The first metal block 401 and the second metal block 501 rotate in opposite directions, causing the first connecting rod 9 and the second connecting rod 10 to rotate synchronously in opposite directions. This opens the first arc-shaped compression plate 16 and the second arc-shaped compression plate 18, stretching the elastic band 19. At this time, the telescopic rod 20 retracts, pulling the center of the elastic band 19 closer to the center of the cannula 1, thus creating a larger gap between the elastic band 19 and the inner wall of the cannula 1, allowing the rectum 24 to be in an open state. (See attached...) Figure 12 As shown.
