Repeat this operation two to three times. The corpus cavernosum can return to normal state.

Description

The invention relates to an artificial inflatable penile erection device (or inflatable penile prosthesis). The device will be implanted in the body of male sexual insufficiency patients caused by irreversible organic diseases to help them restore the normal erectile function of the penis.

Aspect the penis erection aid device, predecessors have proposed several different design schemes. The first type is a pair of cylindrical entities with certain hardness and toughness, which are implanted in the patient's corpus cavernosum (its representative is U.S. Pat. No 3893456). This type of erection aid device has two disadvantages: the one, because the garden column entity has constant hardness, it is still in an erect state when it is not sexual intercourse, and forced bending produces pain and discomfort, which makes the patient's body, mind, work, and life evenly. Affected; The 2nd, garden column entity can not make the length and the diameter of penis increase during sexual intercourse, affects sexual function and effect. The second type of penile erection device is the inflatable type. The most common design of this type includes a pair of inflatable cylindrical hollow bladders implanted in the corpus cavernosum of the patient's penis, a fluid-filled reservoir, flow channels, control valves, and a pump. The reservoir and valve are usually placed in the retropubic pelvis and the control pump is implanted in the scrotum (U.S. Pat. No 4235227). Another design is to implant them into the abdominal cavity (U.S. Pat. No. 3954102). This type of erection device is characterized by the need to press a large amount of fluid into the cylindrical sac in order to ensure the hardness of the penis. Large storage pouch. The third type of penile erection device combines an inflatable cylindrical sac with a cylindrical body (U.S. Pat. No 4353693). This type of erection device reduces the volume of the storage bag, but the central cylindrical body may still cause discomfort after the liquid in the cylindrical bag is emptied. In addition, implanting the pouch and the valve into the scrotum may cause a large foreign body sensation and cause physical and mental pain and discomfort to the patient. U.S.Pat.No 4353360 provides another solution, which is to combine the cylindrical capsule, storage capsule and valve into the penis. The disadvantage is that the cylindrical capsule must be strengthened because the storage capsule is too small, thus causing some problems . In addition, the valve components employed are heavy, which increases patient discomfort.

In conclusion, it is very necessary to design a new type of inflatable penile erection device with smaller volume reservoir, light and reliable valve so that they can be implanted in proper position to eliminate foreign bodies in the scrotum.

The purpose of the present invention is to provide an artificial inflatable penile erection device, which can be implanted due to irreversible organic diseases (such as diabetes, severe penis injury, pelvic trauma, vascular and neurological diseases, and various surgical sequelae). In the body of the patient with male dysfunction caused by it, through the simple operation and control of the body surface, the patient can completely restore the normal penile erection function during sexual intercourse, and in the normal life of non-sexual intercourse, the penile erection can be eliminated by controlling the valve, and the recovery can be restored. The natural state of a non-erect penis. The reservoir and control part of the device can be implanted in appropriate places under the skin of the lower abdomen to eliminate the discomfort and various problems that may be caused by the commonly used control element implanted in the scrotum. The structure of the control part of the device is simple, which reduces the failure factors of the device in the body, and thus has better safety and reliability.

The accompanying drawing is an overall schematic diagram of an inflatable penile erection device, which consists of a pair of cylindrical capsules 1, a pair of support bodies 2, a catheter 6, a surgical joint 7, a pressurized ball 8, a filling opening valve 9, and an emptying opening valve 12 and storage bag 16 constitute. Wherein, valve 9 and 12 constitute the control part of device together with pressurized ball 8, and support body 2 and garden column bag 1 are the parts implanted in the cavernous body of penis.

The gist of the present invention is that valve 9,12 is sealed and fixed between the pressurized ball 8 and the storage bag 16, and the two are isolated, and the filling liquid can only pass through the valves 9 and 12 to enter and exit the pressurized ball 8 from the storage bag 16. The pressurized ball 8 is connected to the support body 2 through the conduit 6 . Between the catheter 6 and the pressurized ball 8 there is a surgical joint 7 . The accompanying drawing also shows a section of the structure implanted in the sponge body of the penis. The filling liquid enters the inner lumen 4 of the support body through the guide tube 5 of the support body 2 through the catheter 6, and then enters the inner cavity of the cylindrical capsule 1 through the circular tube-shaped filling passage 3. The supporting body 2 and the garden column capsule 1 are implanted in the cavernous body of the penis, and the diameter of the junction of the two is the same, and its size is designed according to the anatomical size of the cavernous body. The support body 2 is conical, and its length L can fluctuate between 20%-70% of the length of the cylindrical capsule 1 according to the body difference of the patient. Connect the pipe 6 at the support body connecting pipe 5, and lead it out from the sponge body. The storage bag 16, the pressurized ball 8 and the valves 9, 12 of the control part are implanted in the subcutaneous proper position of the lower abdomen, and the catheter 6 and the pressurized ball 8 are connected with the surgical joint 7 to make the system closed. The attached figure also shows the dissection of the reservoir and the control part, the state is opened in the direction of filling. The valve 9 is a filling opening valve, and its structure is composed of a small hole 10 and a smooth and flat film 11 that can be attached thereto. When the pressure in the storage bag 16 was greater than the pressure in the pressurized ball 8, the valve was opened. Otherwise, the valve is closed. Valve 12 is an emptying opening valve, and 13 is a valve core, which has a flow channel in it and communicates with the storage bag 16 through an aperture. The valve core 13 is wrapped by an elastic membrane 14 and can be opened under a certain pressure. 15 is a porous substance, which is a resistance element of the valve 12, which can enhance the pressure resistance of the valve 12.

After the device is implanted in the body, lightly press the position of the storage bag 16 in the lower abdomen, and the filling liquid can enter the pressurized ball 8 through the filling opening valve 9, and pass through the surgical joint 7, the catheter 6, the supporting body connecting tube 5, and the inner cavity of the supporting body. 4. The garden tubular filling passage 3 enters the inner cavity of the cylindrical capsule 1 to fill the capsule to the required hardness. When the erection of the penis is not needed, press the position of the pressurized ball 8 outside the body by hand, because the pressure of the filling liquid increases to the opening pressure of the emptying opening valve 12, the liquid flows back to the storage bag 16, and the liquid in the cylindrical bag 1 is pumped out by the tension. Put pressurized ball 8, press pressurized ball 8 again, because the resistance of garden tubular filling passage 3 in garden column bag 1 is bigger, flow is limited, pressure in pressurized ball 8 rises again to the unlatching of emptying opening valve 12 Pressure, another part of the liquid flows back to the storage bag 16, so repeated two to three times, the garden column bag 1 can be emptied. Part of the liquid is still stored in the cylindrical channel 3 after emptying, so in fact it plays the role of reducing the volume of the liquid to be emptied, so that the volume of the storage bag 16 is reduced. on the other hand. Because of its hollow structure, its flexibility is better, and it has little influence on the flexibility of the cylindrical capsule 1 after it is emptied.

The present invention has the following advantages compared with the existing penile erection aids: one is that the control part has a simple structure and higher reliability under the premise of ensuring filling and emptying quickly and smoothly; The tubular channel can reduce the amount of liquid that needs to be removed and prevent the cylindrical capsule from wrinkling in the cavernous body. At the same time, the cylindrical capsule is more flexible than the solid column in the center after being emptied; the third is the storage capsule of the device and The control part is implanted under the skin, which eliminates the possible discomfort caused by foreign objects stored in the scrotum of the control device of similar foreign products.

The overall body of the penile erection device of the present invention can be made of various materials that can be implanted in the body for a long time without toxic side effects on the human body and can achieve the required physical and mechanical properties. A more satisfactory example is medical-grade block polyether polyurethane, and the molding method can be any method that can ensure a smooth surface. The valve core of emptying and opening valve can be made of any hard structural material that is nontoxic to the human body, such as stainless steel. The elastic film can be any material that has no toxic side effects on the human body, and has appropriate elasticity and aging resistance. The porous substance can be any porous substance that has no toxic side effects on the human body.
