Description

Technical Field

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

[0002] Currently, ion-exchange polymer metal composites (IPMCs) are a class of electroactive polymer materials often referred to as artificial muscles. When a voltage is applied to the thickness of an IPMC material, it undergoes mechanical deformation; conversely, when mechanical action is applied, it outputs current. This combined sensing and actuation characteristic allows it to form intelligent structures with self-sensing and adaptive response capabilities. Furthermore, IPMCs can be cut into arbitrary sizes and shapes, are lightweight and flexible, and can perform multi-degree-of-freedom movements. Because their performance resembles that of biological muscles, they are called "artificial muscles." Compared to traditional actuators and motors, "muscle" actuators made of these electroactive polymers can eliminate most mechanical components such as gears and transmission rods. Moreover, IPMCs can produce large displacement and deformation responses even with relatively low driving voltage excitation, thus attracting increasing attention and showing great promise for applications in microelectromechanical systems (MEMS), biomedicine, and biomimetic mechanisms.

[0003] In the field of cancer, the incidence of colorectal cancer is rising year by year, seriously threatening people's quality of life and social development. Patients with rectal cancer, especially low rectal cancer, often face the dilemma of not being able to preserve their anus. With current technology, the only way to save their lives is through sigmoid colostomy. During the operation, it is generally necessary to create a colostomy in the patient's lateral wall and use a colostomy bag to solve the patient's excretion problem.

[0004] However, patients often experience an unpleasant odor from the stoma site after surgery, and the stoma bag needs to be changed frequently, which is very cumbersome and embarrassing. At the same time, carrying the stoma bag with them makes it very inconvenient for patients to move around. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0040] like Figures 1-3 As shown, the implantable intelligent artificial anus provided in this embodiment of the invention includes: a driving mechanism 100 and an intestinal mechanism 200; the intestinal mechanism 200 is disposed in the patient's body, one end of the intestinal mechanism 200 is connected to the patient's intestine, and the other end of the intestinal mechanism 200 extends out of the patient's body so that the excrement in the patient's intestine can be discharged out of the body through the intestinal mechanism 200; multiple driving mechanisms 100 are provided, each driving mechanism 100 is disposed on the intestinal mechanism 200, the multiple driving mechanisms 100 are arranged at intervals along the length direction of the intestinal mechanism 200, each driving mechanism 100 is connected to the intestinal mechanism 200, and the multiple driving mechanisms 100 can drive the intestinal mechanism 200 to move sequentially along the direction of the patient's excretion.

[0041] In an optional embodiment, the intestinal mechanism 200 includes an external intestine 210 and an internal intestine 220; the external intestine 210 is sleeved on the internal intestine 220, and a gap is left between the external intestine 210 and the internal intestine 220. The drive mechanism 100 is disposed in the gap and is connected to the external intestine 210 and the internal intestine 220 respectively.

[0042] It should be noted that the patient's intestine can extend into the gap and connect with the inner wall of the external intestine 210 and the outer wall of the internal intestine 220 respectively, so that excrement in the patient's intestine can be excreted into the internal intestine 220. The drive mechanism 100 may include an IPMC to make the drive mechanism 100 more energy-efficient during the drive process. At the same time, the IPMC can mimic the peristalsis of the intestine. When the patient needs to defecate, the excrement enters the internal intestine 220 through the connection between the internal intestine 220 and the patient's intestine, and slides to the other end of the internal intestine 220. Multiple drive mechanisms 100 move sequentially along the flow direction of the excrement to drive the excrement. The mechanism 100 can drive excrement out of the body through the inner intestine 220. The driving mechanism 100 can reciprocate and drive the inner intestine 220 multiple times during the patient's excretion process, thereby making the patient's excretion smoother. At the same time, the length of the inner intestine 220 and the outer intestine 210 can be customized according to the patient's condition, so that the patient does not need to perform an abdominal wall stoma and avoids the patient's long-term use of a stoma bag. The inner intestine 220 and the outer intestine 210 can be made of medical silicone. The inner diameter of the inner intestine 220 can be set to 25-30 mm, and the width of the gap can be set to 2 mm to meet the needs of connection with the patient's intestine.

[0043] Optionally, the intestinal mechanism 200 can also be configured as an artificial intestine. The intestinal mechanism 200 can be made of medical-grade silicone. During the manufacturing process of the intestinal mechanism 200, the drive mechanism 100 is pre-installed inside the intestinal mechanism 200.

[0044] The implantable intelligent artificial anus provided in this embodiment of the invention includes: a driving mechanism 100 and an intestinal mechanism 200; the intestinal mechanism 200 is disposed inside the patient's body, one end of the intestinal mechanism 200 is connected to the patient's intestine, and the other end of the intestinal mechanism 200 extends outside the patient's body, so that excrement in the patient's intestine can be discharged through the intestinal mechanism 200, eliminating the need for abdominal wall stoma during surgery; multiple driving mechanisms 100 are provided, each driving mechanism 100 is disposed on the intestinal mechanism 200, and the multiple driving mechanisms 100 are arranged at intervals along the length direction of the intestinal mechanism 200, each driving mechanism 100... Connected to the intestinal mechanism 200, multiple drive mechanisms 100 can drive the intestinal mechanism 200 to move sequentially along the direction of patient excretion. Thus, during the patient's defecation process, multiple drive mechanisms 100 can mimic intestinal peristalsis, making the patient's defecation smoother. This alleviates the technical problems of existing technologies, such as patients having odor at the stoma site for many years after surgery, the need for frequent changes of the stoma bag, which is very cumbersome and embarrassing to use, and the inconvenience caused by patients carrying the stoma bag. This technology achieves the technical effect of eliminating the need for the stoma bag, reducing postoperative odor, and making defecation smoother and movement more convenient for patients.

[0045] In an optional embodiment, the drive mechanism 100 includes a drive ring 110, a first contact piece 120, and a second contact piece 130. The drive ring 110, the first contact piece 120, and the second contact piece 130 are all disposed within the gap. The drive ring 110 is disposed on the inner tract 220 and connected to the inner tract 220. The two ends of the drive ring 110 are respectively connected to the first contact piece 120 and the second contact piece 130. The first contact piece 120 and the second contact piece 130 are disposed opposite to each other. The first contact piece 120 is disposed on the outer tract 210 and connected to the outer tract 210. The second contact piece 130 is disposed on the inner tract 220 and connected to the inner tract 220. The inner tract 220 can compress the gap so that the second contact piece 130 moves in a direction close to the first contact piece 120.

[0046] In an optional embodiment, multiple drive rings 110 are provided, and both ends of each drive ring 110 are connected to the first contact piece 120 and the second contact piece 130. The multiple drive rings 110 are arranged at intervals along the length direction of the inner intestine 220.

[0047] In this embodiment, each drive mechanism 100 may include three drive rings 110. The three drive rings 110 are all disposed on the outer surface of the inner intestine 220 and connected to the inner intestine 220. One end of the three drive rings 110 can be connected to the first contact piece 120, and the other end of the three drive rings 110 can be connected to the second contact piece 130. The three drive rings 110 are evenly arranged along the length of the inner intestine 220, making it easier for excrement in the inner intestine 220 to be discharged from the body.

[0048] In an optional embodiment, a power cord 300 is also included; the power cord 300 is disposed within the gap and between the first contact 120 and the second contact 130, and the second contact 130 is capable of pushing the power cord 300 to move in a direction close to the first contact 120 so that both sides of the power cord 300 abut against the first contact 120 and the second contact 130 respectively.

[0049] In this embodiment, the drive ring 110 is C-shaped and can be an IPMC. The drive ring 110 covers the inner intestine 220 along its outer surface. The drive ring 110 can be fixedly connected to the inner intestine 220 by adhesive to prevent separation during the driving process. The movement of the drive ring 110 includes diameter reduction and diameter increase to mimic intestinal peristalsis. It can also squeeze excrement through the inner intestine 220. The first contact 120 and the second contact 130 can be conductive copper sheets. The two ends of the drive ring 110 are respectively fixed to the first contact 120 and the second contact 130. The connection is fixed. The second contact 130 is disposed on the outer surface of the inner intestine 220, and the first contact 120 is disposed on the inner surface of the outer intestine 210. When the patient needs to defecate, the excrement enters the inner intestine 220, causing the inner intestine 220 to deform. The inner intestine 220 compresses the gap, making the gap smaller, and the distance between the first contact 120 and the second contact 130 smaller. This causes the positive and negative ends of the power cord 300 to abut against the first contact 120 and the second contact 130, respectively, energizing the drive ring 110 and starting to drive the inner intestine 220. After the inner intestine 220 senses the excrement, the drive ring 110 automatically starts to drive the peristalsis of the inner intestine 220, making defecation smoother and more convenient.

[0050] Optionally, a signal output is also included; the signal output is connected to the power cord 300, the first contact 120 and the second contact 130 respectively. When the first contact 120 and the second contact 130 are connected to the power cord 300 respectively, the signal output transmits a signal to the patient. The transmitted signal includes wireless signals and wired signals, such as reminding the patient to defecate by sending a message to the patient's mobile phone APP or to the alarm device held by the patient.

[0051] In an optional embodiment, an anal mechanism 400 is also included; the anal mechanism 400 is disposed at the end of the intestinal mechanism 200 away from the patient's intestine, the anal mechanism 400 is connected to the end face of the intestinal mechanism 200, and the anal mechanism 400 is used to control the communication or closure between the inside of the intestinal mechanism 200 and the outside.

[0052] In an optional embodiment, the anal mechanism 400 includes a door panel 410 and an air bladder 420; the door panel 410 is provided with a plurality of excretion holes, which are arranged along the circumference of the door panel 410, and the door panel 410 is connected to the end face of the intestinal mechanism 200. Each excretion hole is used to discharge excrement; a plurality of air bladders 420 are provided, each air bladder 420 is disposed in one excretion hole, and each air bladder 420 is used to block the excretion hole.

[0053] In an optional embodiment, the anal mechanism 400 further includes an IPMC; the IPMC is disposed inside the air bladder 420 and connected to the air bladder 420. The IPMC is used to control the expansion and contraction of the air bladder 420 so that the intestinal mechanism 200 can communicate with or close to the outside through the excretion hole.

[0054] In this embodiment, the door panel 410 is circular and seals the end of the inner intestine 220 and outer intestine 210 away from the patient's intestine. The door panel 410 is connected to the inner wall of the outer intestine 210, and each excretion hole on the door panel 410 corresponds to the inner wall of the inner intestine 220, so that excrement in the inner intestine 220 can be discharged from the body through multiple excretion holes. For example... Figure 2 As shown, each excretion hole is elliptical, and multiple excretion holes are arranged at intervals along the circumference of the door panel 410. These multiple excretion holes can be of different sizes to facilitate smoother excretion. Furthermore, an air bladder 420 is provided within each excretion hole. Each air bladder 420, after inflating, is press-fitted with the inner wall of its corresponding excretion hole to prevent excrement from flowing out through the gap between the air bladder 420 and the excretion hole. An IPMC is disposed within the air bladder 420, arranged along its inner surface. The IPMC can expand or contract, causing the air bladder 420 to expand or contract as well. When excretion is needed, the IPMC contracts, causing the air bladder 420 to contract, allowing excrement from the intestinal tract 220 to be expelled through the excretion hole. After excretion, the IPMC expands, causing the air bladder 420 to inflate and tightly connect with the excretion hole, thus preventing excrement from flowing out through the gap between the air bladder 420 and the excretion hole, making excretion more convenient.

[0055] In an optional embodiment, the anal mechanism 400 further includes a flushing hole; the flushing hole is disposed on the door panel 410 and communicates with the intestinal mechanism 200, and the flushing hole is used to deliver liquid into the intestinal mechanism 200.

[0056] In this embodiment, the flushing liquid includes physiological saline. One end of the flushing hole is located on the door panel 410, and the other end of the flushing hole is located on the internal intestine 220 and connected to the inner wall of the internal intestine 220. A one-way valve is provided in the flushing hole. The one-way valve can only allow the external cleaning liquid to enter through the flushing hole on the door panel 410 and flush the internal intestine 220, so as to prevent excrement from flowing out through the flushing hole during normal use. At the same time, it can also prevent excrement from blocking the internal intestine 220 during defecation, thus preventing the patient from having difficulty defecating.

[0057] In an optional embodiment, a power supply 500 is also included; the power supply 500 is disposed on the door panel 410, connected to the door panel 410, and electrically connected to the IPMC and the drive mechanism 100, and the power supply 500 is used to supply power to the IPMC and the drive mechanism 100.

[0058] In this embodiment, the power supply 500 includes a battery, is disposed on the door panel 410, is connected to the door panel 410, and is connected to the IPMC, power line 300 and signal output electrical signal inside the airbag 420 respectively. The power supply 500 is used to supply power to the IPMC, power line 300 and signal output inside the airbag 420.

[0059] Optionally, a control mechanism is also included. The control mechanism is installed on the door panel 410 and is electrically connected to the IPMC inside the airbag 420 and the power supply 500. The control mechanism is used to control the expansion or contraction of the IPMC inside the airbag 420, so that the patient's defecation timing can be controlled.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
