Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and particularly relates to an artificial anal sphincter for defecation reminder and control and a use method thereof. Background Art

[0002] Clinically, patients with rectal cancer often need to have their rectum, part of the colon and anal sphincter removed, resulting in loss of anal sphincter function and fecal incontinence. In this case, the patient's colon needs to be stomated in the abdominal wall, exposing the end of the intestine to the abdominal surface to artificially create a fecal outlet, and a fecal bag needs to be hung on the outside of the abdominal wall to catch the discharged feces, which brings great inconvenience and pain to the patient. The fecal bag covering the surface of the abdominal wall may also cause infection, allergies and other problems.

[0003] At present, in the prior art, an artificial anal sphincter is usually used to solve fecal incontinence caused by sphincter damage or loss. For example, US7011622B2 discloses an artificial anal sphincter, which is realized by squeezing the liquid in the pressure regulating ball into the clamp bag through a manual squeezing control pump. However, this solution has many shortcomings. It cannot monitor the intestinal pressure in real time, and cannot adjust the pressure of the clamp bag according to the intestinal pressure, which may cause ischemia and necrosis of the intestinal tube. Manual adjustment is also inconvenient in operation. The difference in individual hand feel may also cause the problem of over-squeezing or under-squeezing. Another example is the finger-button artificial anal sphincter disclosed in CN103637859A. This technology uses a micromotor, a finger joint mechanism and a drive rope to shrink the inner diameter of the finger joint mechanism to achieve the function of the artificial anal sphincter. However, this technology has a complex structure, and the relaxation of the finger joint mechanism depends on the pressure of the intestinal tube itself. The mechanical structure and the intestinal position are relatively fixed, which may cause ischemia due to the squeezing of the local intestinal tube, making it inconvenient to control defecation, etc.

[0004] That is, how to provide an artificial anal sphincter for defecation reminder and control, which has defecation reminder and defecation control functions, avoids ischemia and necrosis of the intestinal tract, and is easy to operate, is a technical problem that technical personnel in this field urgently need to solve.

[0034] Specifically, the present invention provides an artificial anal sphincter for defecation reminder and control, comprising an inflation and deflation device 1, a control processing device 2, a circulation extrusion device 3, a defecation monitoring device 4 and a vibration motor 5. The control processing device 2 placed in the abdominal cavity 8 is connected to the inflation and deflation device 1. The circulation extrusion device 3 comprises a low-position extrusion airbag component 33, a middle-position extrusion airbag component 32 and a high-position extrusion airbag component 31 which are adjacently arranged on the periphery of the colon 10 along the colon skin anastomosis 9 toward the colon 10. The low-position extrusion airbag component 33 is located at the colon skin anastomosis 9. The inflation and deflation device 1 can be controlled to be opened or closed by the control processing device 2, so as to adjust the high-position extrusion airbag component 31 and the middle-position extrusion airbag component 32 through the inflation and deflation device 1 connected to the circulation extrusion device 3. The high-position squeezing airbag 31, the middle-position squeezing airbag 32 and the low-position squeezing airbag 33 are inflated to expand the high-position squeezing airbag 31, the middle-position squeezing airbag 32 and the low-position squeezing airbag 33 so as to clamp the colon 10 from the periphery of the colon 10, and shrink the bottom end of the colon 10 when not defecating so that the stool is stored in the intestine to avoid fecal incontinence. When defecation is needed, the high-position squeezing airbag 31, the middle-position squeezing airbag 32 and the low-position squeezing airbag 33 can be deflated by the inflation and deflation device 1 to loosen the colon 10 for defecation, thereby realizing the defecation control function of the anal sphincter.

[0049] Those skilled in the art will appreciate that the wireless charging coil 61 buried in the subcutaneous tissue of the ischial tuberosity is electrically connected to the power source 22. The patient can sit on the wireless charging cushion 62 to achieve wireless induction connection between the wireless charging coil 61 and the wireless charging cushion 62 connected to an external power device, so as to charge the power source 22 through the wireless charging cushion 62 and the wireless charging coil 61.

[0053] This is because the air storage bag 13 is filled with carbon dioxide gas, and each air bag is inflated by carbon dioxide gas, which can avoid the problem of secondary surgery caused by liquid leakage due to the use of liquid; and when carbon dioxide leaks, it can be quickly dissolved into the blood and tissue fluid in the body to form carbonic acid, and discharged from the body through the lungs in the form of carbon dioxide without forming gas embolism, which can avoid the risk of using other inert gases or nitrogen or oxygen because they may not be easily soluble in the blood and form gas embolism and cause serious complications.

[0054] Embodiment 2:

[0055] Embodiment 2 of the present application provides a method for using an artificial anal sphincter, comprising the following steps:

[0056] S101 installs the artificial anal sphincter;

[0057] After the installation is completed, S102 determines the pre-filling pressure of the capacity sensing airbag 411 and the pre-filling capacity of the pressure sensing airbag 421;

[0058] S103 cyclically inflates the low squeeze airbag, the middle squeeze airbag and the high squeeze airbag in sequence;

[0059] S104 uses the pre-filling pressure to inflate the capacity sensing airbag 411, and uses the pre-filling capacity to inflate the pressure sensing airbag 421;

[0060] After the inflation is completed in step S105, the gas capacity in the capacity sensing airbag 411 and the airbag pressure in the pressure sensing airbag 421 are detected, and whether the best time for defecation is reached is determined according to the gas capacity and the airbag pressure;

[0061] S106: If yes, the low-position squeezing airbag, the middle-position squeezing airbag and the high-position squeezing airbag are deflated. After deflation is completed, steps S103 to S105 are repeated; if no, step S105 is repeated until the best time for defecation is reached.

[0062] In some possible embodiments, in step S101, the installation of the artificial anal sphincter includes: after the rectum, anal canal and part of the sigmoid colon are removed in the colon, the colon to be anastomosed (descending colon or sigmoid colon) is passed through the pressure sensing airbag 421, the high-position squeezing airbag, the middle-position squeezing airbag and the low-position squeezing airbag in sequence, so that each airbag wraps the colon, and then the colon is pulled down to the anus position, and directly anastomosed with the skin around the anus to form a colon skin anastomosis 9; the wireless charging coil 61 is buried in the subcutaneous tissue corresponding to the ischial tuberosity to facilitate the subsequent use of the wireless charging cushion 62 to automatically charge when the patient is on the cushion; the vibration motor 5 is placed near the anus, and the NFC coil 23 is buried in the subcutaneous tissue on the outside of the buttocks to facilitate the use of the NFC bracelet 24 for control during defecation; the air storage bag 13 is placed in the space behind the pubic bladder, and the implantable gas supply port 71 is buried in the subcutaneous tissue to facilitate the subsequent in vitro gas replenishment operation. Among them, all implanted devices are made of materials with good biocompatibility with the human body, do not produce anastomosis with human tissue, and have good compatibility.

[0063] In some possible embodiments, in step S102, determining the pre-fill pressure of the capacity sensing airbag 411 and the pre-fill capacity of the pressure sensing airbag 421 includes: progressively inflating the capacity sensing airbag 411 with a constant pressure from low to high, and progressively inflating the pressure sensing airbag 421 with a constant volume from low to high, and recording the volume and pressure of the capacity sensing airbag 411 and the pressure sensing airbag 421 at different times for a period of time through the main control processor 21 and outputting the recorded data to the external control processor, observing and adjusting the data accordingly, determining the pre-fill pressure of the capacity sensing airbag 411 and the pre-fill capacity of the pressure sensing airbag 421 suitable for different individuals, and calculating the best time for defecation, so as to correct and adjust the contraction pressure of the anal sphincter according to individual differences and different intestinal pressures during defecation. The correction and adjustment should be based on the individual conditions of different patients, so that the minimum pressure used when not defecating, that is, to ensure that the stool is not leaked, can reduce the occurrence of ischemic necrosis, and the pressure used during defecation can help the patient defecate smoothly.

[0064] In some possible embodiments, in step S106, the deflating of the low-position squeezing airbag, the middle-position squeezing airbag and the high-position squeezing airbag includes: when the stool in the colon increases to reach the calculated optimal defecation time, the main control processor 21 sends a signal to the vibration motor 5 to vibrate and remind the patient; when the patient takes the time to prepare for defecation, the NFC bracelet 24 can be used to align with the NFC coil 23 to activate the defecation mode. At this time, the air in the low-position squeezing airbag, the middle-position squeezing airbag and the high-position squeezing airbag is drawn back into the air storage bag 13 through the air pump 11 to deflate the low-position squeezing airbag, the middle-position squeezing airbag and the high-position squeezing airbag, and the filling of the air storage bag 13 will also compress the bladder at the same time to help urination.

[0065] After deflation is completed, that is, after defecation is completed, the NFC bracelet 24 is used again to approach the NFC coil 23, and then the defecation is ended, and the daily activity mode is entered, and the subsequent steps S103-step S105 are repeated. When the best defecation time is not reached, the daily activity mode is also entered. At this time, by detecting the capacity and pressure of the capacity sensing airbag 411 and the pressure sensing airbag 421, the low-position squeezing airbag, the middle-position squeezing airbag and the high-position squeezing airbag are cyclically inflated in sequence using the lowest pressure, so as to achieve the following effects: when there is little pressure on the stool in the colon, the pressure of the low-position squeezing airbag, the middle-position squeezing airbag and the high-position squeezing airbag is reduced, and when there is a lot of stool in the colon and the pressure is high, the pressure of the low-position squeezing airbag, the middle-position squeezing airbag and the high-position squeezing airbag is increased; when the stool in the colon reaches the best defecation time, the patient is reminded to defecate as soon as possible. In this way, the pressure of the low-position squeezing airbag, the middle-position squeezing airbag and the high-position squeezing airbag on the intestine can be reduced to the greatest extent, and the occurrence of ischemic necrosis can be avoided.

[0066] When it is detected that the gas in each airbag is reduced or individual adjustment is required, the air storage bag 13 can be inflated or deflated by inserting the implantable air supply port 71 with an air replenishment needle 73 outside the body; when the power supply 22 is low on electricity, the vibration motor 5 can be controlled by the main control processor to start different vibration modes (such as long, short, double, triple vibration, etc.) to remind the patient that the power supply 22 needs to be charged. During the charging operation, the patient only needs to sit on the wireless charging cushion 62 and make the wireless charging coil 61 correspond to the correct position.
