Provided are artificial muscle patches, which are adapted to be implanted adjacent a patient's heart, and artificial sphincter cuffs, which are adapted to be implanted around a body lumen, such as the urethra, the anal canal, or the lower esophagus. The devices of the present invention comprise: (a) one or more electroactive polymer actuators; and (b) a control unit for electrically controlling the one or more electroactive polymer actuators to expand or contract the devices.

Devices and methods for preventing or reducing the severity of hemorrhoids include a raised portion and a base, where the raised portion extends in a first direction away from the base and is shaped to engage and apply pressure to a region of a patient subject to hemorrhoids. The devices may further include a plug for insertion into the anal canal to engage and apply pressure to another region of the patient subject to hemorrhoids. The methods include securing the device in an engagement position to apply the pressure to prevent or reduce the severity of hemorrhoids. Such devices and methods are especially applicable during the childbirth process.

A multifunctional medical tool for use in proctologic applications, during which a surgeon has to manipulate a surgical instrument, brought within the anal canal. The tool comprises a pistol-grip portion (10) to carry the surgical instrument, an endoscopic means (30') for insertion within the anal canal and a surgical instrument (56), which can be brought in the anal canal through the endoscopic means (30'). The tool can be used for endoscopic examination or for various invasive proctologic treatments within the anal canal, rectum or distal colon.

The invention discloses an anus dilatation device for a surgical operation, comprising a hollow body and an outward-expanding broadside, wherein the broadside is connected to the near end of the body, the body comprises at least two groups of matched anus dilatation sheets between which a gap exist, and therefore the far ends of the anus dilatation sheets become gathered together from mutually departing. The anus dilatation device can gradually and controllably dilatate the anus and the anal tube of a patient so as to avoid anal fissure and lighten the pain of the patient. Meanwhile, the processes of anus pre-dilataton and anus dilatation are integrally designed, and thus the product is convenient and simple to use. The anus dilatation device can be widely applied in the surgical operations.

Today's suppositories are typically packaged individually for digital administration into the anal canal of a patient. A suppository applicator described herein, which works with individually packaged suppositories, can alternatively be shipped in a prepackaged operational arrangement with a suppository to enable the patient to administer the suppository through use of the applicator in a single operation after opening a hygienic wrapper containing the applicator-suppository combination. A method for manufacturing a suppository includes manufacturing the suppository in the presence of and in contact with an element configured to be used to insert the suppository into a body cavity. The method may include using the element to define a shape of the sup pository during the manufacturing. The resulting applicator-suppository combination is more hygienic and easier to handle than the separate applicator and suppository and provides more efficiency from time of opening the packaging to time of commencing administration of the suppository.

The invention discloses an anal levator shaft plane image processing method and a device thereof. The method is characterized by acquiring three-dimensional volume data of a basin floor; according to the three-dimensional volume data, carrying out image detection on a basin-floor-center sagittal image and identifying a pubic symphysis lower margin and a rectum and anal canal connection portion; acquiring a connection line of the pubic symphysis lower margin and the rectum and anal canal connection portion, adjusting the connection line and making the connection line be in a horizontal direction; and according to the connection line of the horizontal direction, adjusting a sampling frame and acquiring an anal levator shaft plane image. By using the anal levator shaft plane image processing method and the device thereof, the pubic symphysis and the rectum and anal canal connection portion can be automatically identified so that the sampling frame is rapidly and accurately adjusted and an anal levator area image is acquired; and accuracy and efficiency of image processing are increased.

The invention discloses a hemostatic device of a recto and an anal canal. The hemostatic device comprises a hemostatic tube body, a gauze sleeve and an auxiliary plug rod, the hemostatic tube body comprises a first tube opening and a second tube opening at two ends, and a first flange is arranged on the outer edge of the first tube opening, fixing holes are formed in the flange, and multiple medicine holes are formed in the tube wall of the hemostatic tube body; two ends of the gauze sleeve are open, and the gauze sleeve is connected to the hemostatic tube body in a sleeving mode; the auxiliary plug rod can be inserted into the hemostatic tube body and limited through a second flange which is arranged in the second tube opening. The hemostatic device can effectively stop bleeding by compression, not only takes a hemostatic effect, but also avoids anastomotic stoma injury and wound bleeding, and the diameter of the column-shaped device can be adjusted in a seriation mode, so that the hemostatic device accords with the anal canal diameter of different patients. Meanwhile, it is guaranteed that the hemostatic device cannot slide out automatically through multiple modes, the hemostatic device can also be prevented from retrograding into the recto, the hemostatic device is prevented from sliding out too early and thus cannot take the effect of stopping bleeding, and the situation is avoided that since materials are placed again, sufferings of the patients are increased.

The invention discloses an anal tube for use in the treatment of anorectal diseases, which belongs to the technical field of medical apparatus and instruments for use in surgical operation. The invention adopts a technical scheme that: an expansion cell is expanded to pressure a wound to stop bleeding; intestinal contents are discharged from an aspiration tube; an irrigator is used to irrigate the intestinal tract; and thus, anastomotic leakage rate after low rectal carcinoma is lowered, excrement can be transferred radically, infection is controlled and the healing of the wound is promoted. The expansion cell can be expand and contract by injecting and pumping liquid or gas, the contracted expansion cell can be pulled out of and inserted into the rectum and anus, the expansion cell expanded in the rectum and anus can press the wound to stop bleeding, a hollow channel is formed in the expansion cell, and an aspirator and the irrigator are arranged in the hollow channel.
