The invention provides a magnetic force driven alternate clamping type artificial anal sphincter prosthesis, which comprises an upper clamping device, a lower clamping device, an upper clamping device and a lower clamping device, wherein the upper clamping device is used for clamping a first part of an intestinal tract and can be opened or closed through magnetic force driving; the lower clamping device is used for clamping a second part of the intestinal tract and can be opened or closed through magnetic force driving, and the magnetic force threshold value of the lower clamping device is larger than that of the upper clamping device; the linkage part is connected with the upper clamping device and the lower clamping device and enables the upper clamping device and the lower clamping device to be in linkage. According to the artificial anal sphincter device, a magnetic force driving mode is adopted, the upper clamping device and the lower clamping device are used for alternately clamping an intestinal canal, clamping is carried out in a large-area plane, an excrement temporary storage stage is preset, an intestinal pressure monitor is matched for defecation early warning, and manual operation is not needed; the artificial anal sphincter prosthesis can effectively reduce the risk of injury and infection caused by the fact that the intestinal tract is in a clamping state for a long time, and is safe, stable, good in excrement control and convenient in energy supply.

This invention discloses an intelligent bionic artificial anus system, comprising: a sphincter module, a pressure sensor, and a controller. The pressure sensor and controller are disposed within the sphincter module. The sphincter module is located on the outer side of the human intestine and constricts the intestine. The pressure sensor detects a first pressure emanating from inside the intestine and sends the first pressure value to the controller. The controller issues an opening command when the first pressure value meets a first condition. The sphincter module reduces the external pressure applied to the intestine based on the opening command, causing the intestine to open. The controller issues a closing command when the first pressure value meets a second condition. The sphincter module closes the intestine based on the closing command. This allows patients who have had their anus removed to regain anal function, enabling them to defecate, work, live, and exercise normally without the need for a stoma, thus improving their quality of life.

The invention relates to an artificial anal sphincter system based on defecation perception. The artificial anal sphincter system comprises a defecation perception module, a driving module, an execution module, a control circuit and a single-chip microcomputer control module. The defecation perception module comprises a sensor, an alarm module and a screen display module; the defecation perception module, the driving module and the execution module are all connected with the control circuit. When the patient needs to defecate, the execution module controls the clamping mechanism to release the rectum, and normal defecation is carried out; after defecation is finished, the execution module clamps the rectum again, and the sensor replaces normal rectal nerves. Compared with the prior art, the device simulates the contraction mechanism of the sphincter, the movement of the upper clamping plate and the lower clamping plate acts on the intestinal canal, the closed state of the intestinal canal tissue is simulated, a complex mechanical structure is avoided, the effectiveness of the artificial sphincter is improved, the defecation sense sensing function of the rectum and the sphincter group is remodeled, and the practicability is higher.

The application provides an implantable intelligent artificial anus, and relates to the technical field of medical devices, and comprises a driving mechanism and a bowel mechanism; excrement in the bowel of a patient can be discharged out of the body through the bowel mechanism, so that the patient does not need to perform fistulization on the abdominal wall during a surgical process; each driving mechanism is connected with the bowel mechanism, and a plurality of driving mechanisms can drive the bowel mechanism to move in turn along the direction of excretion of the patient, so that the bowel peristalsis can be simulated through the plurality of driving mechanisms during the excretion process of the patient, the excretion of the patient is smoother, and the technical problem that the patient postoperatively always accompanies the odor of the fistulization site for many years, and the fistulization bag needs to be frequently replaced, which is very cumbersome and embarrassing to use, and the patient carries the fistulization bag, causing very inconvenient movement is solved, the patient does not need to use the fistulization bag, the odor of the patient postoperatively is reduced, the excretion of the patient is smoother, and the movement is more convenient.

The utility model discloses a kind of bag orifice sealing structure, artificial anus bag and enema device, belong to medical appliance technical field, aim at solving the problem of existing artificial anus bag without special operation channel, anus temperature measurement or enema operation needs to tear bag and lead to perianal skin damage, the problem of cumbersome operation.Pocket orifice sealing structure includes pedestal, sealing plug and sealing plug, sealing plug is provided with recess and self-closing gap, can be inserted for instrument;Artificial anus bag includes artificial anus bag body, and the bag orifice sealing structure of the artificial anus bag body is set;Enema device includes enema bag, enema tube and the aforementioned artificial anus bag, and enema tube is equipped with moffett dropper and flow regulator.The utility model can complete nursing operation without disassembling artificial anus bag, avoid perianal skin breakage, reduce patient's pain, simplify medical care operation simultaneously, improve nursing convenience.

The invention relates to an anorectal outer surrounding magnetic drive type artificial anal sphincter system which comprises an intestinal tube outer surrounding cavity body, a magnetic flexible material and a flange which wrap the rectum and are sequentially connected, an opening is formed in the intestinal tube outer surrounding cavity body, and the magnetic flexible material and the flange are fixedly connected to the opening; the hip implantation magnet is implanted in the position, close to the anus, of the hip fat layer of the human body; the in-vitro wearing device is arranged at the lower position of the back waist of the human body, and a strong permanent magnet is arranged in the in-vitro wearing device; by wearing and taking off the in-vitro wearing device, the magnetic attraction effect of the strong permanent magnet and the magnetic flexible material is controlled, then the pressure of the magnetic flexible material on the rectum is controlled, and defecation control is achieved. Compared with the prior art, the device has the advantages that the device conforms to the in-vivo structure of the human body, the in-vivo device is fixed relative to the intestinal tract position, the in-vitro device is designed in a wearable mode and is easy to maintain, defecation early warning can be more intuitive through cooperation with the pressure detection sensing module, and biocompatibility is good.

This utility model relates to the field of medical device technology and discloses an intelligent anus with an artificial intestine, including an artificial intestine body and an artificial anus body connected to the artificial intestine body; a pressure transmission unit is connected between the artificial intestine body and the artificial anus body, and the pressure transmission unit is used to control the passage of excrement within the artificial intestine body; both the artificial intestine body and the artificial anus body are equipped with pressure sensing units, and the pressure sensing units are used to monitor the pressure within the artificial intestine body and the artificial anus body, thereby realizing the discharge of excrement within the artificial intestine body through the pressure transmission unit. This utility model proposes an intelligent anus with an artificial intestine, which, through intelligent pressure monitoring, allows patients to autonomously control excretion according to prompts, making it convenient and user-friendly.
