Description

Technical Field

[0001] The present invention relates to the field of medical equipment and supplies, and in particular to a penis implant prosthesis. Background Art

[0002] Erectile dysfunction is a common disease in clinical practice. With the changes in the environment and people's physical fitness, the incidence rate is getting higher and higher. At present, drug treatment is often used in clinical practice. For those with severe erectile dysfunction or those who are not suitable for taking medication, penile implant surgery can be used. For example, those who have sexual nerve damage due to car accidents, work injuries, etc., or those who are not suitable for taking medication due to diabetes, high blood pressure, etc., often choose an ultimate treatment method - penile implant surgery. This surgery is more common in developed countries, and my country is also gradually beginning to use it.

[0003] The penile implant surgery is to implant the penile implant into the cavernous cavity of the penis to replace the patient's cavernous body that has lost its function. At present, the choice of prosthesis includes single-piece, double-piece and three-piece sets, and the inflatable three-piece set is more commonly used. The three-piece penile implant prosthesis is divided into three parts. The first part is two hollow cylinders, also called artificial cavernous bodies, the second part is a water pump, and the third part is a reservoir. Generally, the cylinder is implanted into the cavernous cavity of the penis, the water pump is implanted into the scrotum, and the reservoir is implanted in front of the bladder in the lower abdomen. The three are connected by a catheter. When not in use, the liquid is stored in the reservoir. When needed, the pump is started by hand to allow the liquid in the reservoir to enter the hollow cylinder to make the penis erect. When not in use, the pump is operated to allow the liquid to flow back into the reservoir.

[0004] Although this method solves erectile dysfunction, it has many components, high surgical requirements, and is more traumatic to the patient. Moreover, the operation is cumbersome and requires the patient to operate repeatedly, which is inconvenient to use. In addition, more components and more pipes mean a higher probability of failure. Once a failure occurs, reoperation is required, which brings great pain to the patient.

[0043] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0044] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "front", "rear", "head", "tail", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0045] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0046] Reference Figure 1A To Attachment Figure 3 As shown, a penis implant prosthesis according to a first preferred embodiment of the present invention is schematically shown. In this embodiment, the penis implant prosthesis comprises a body 10, a head end extension section 20 and a tail end extension section 30, wherein the head end extension section 20 and the tail end extension section 30 are detachably connected to the front end and the rear end of the body 10, respectively, and by changing the length of the head end extension section 20 and the tail end extension section 30, the length of the body 10 can be changed, and then the length of the penis implant prosthesis can be changed to meet the use requirements of different patients.

[0047] In addition, the penile implant prosthesis also includes at least one outer sleeve 40, which is detachably sleeved on the main body 10, the head end extension section 20 and the tail end extension section 30, and multiple outer sleeves 40 can be sleeved in sequence, so that the thickness of the penile implant prosthesis can be adjusted to meet the needs of different patients.

[0048] The outer sleeve 40 includes a tube body 41, and the outer sleeve 40 has a sleeve cavity 42 and a sleeve port 43, wherein the sleeve port 43 is connected with the sleeve cavity 42, wherein the sleeve cavity 42 is arranged inside the tube body 41, and the sleeve port 43 is arranged at the end of the tube body 41. The shape of the tube body 41 is the same as the shape of the main body 10, the head end extension section 20 and the tail end extension section 30 after being connected, that is, the head end of the tube body 41 is the same as the shape of the head end extension section 20, which is a rounded conical structure, or a cap-shaped structure, and the sleeve cavity 42 changes according to the shape of the tube body 41.

[0049] When it is necessary to sleeve the tube body 41 on the outside of the main body 10, the head end extension section 20 and the tail end extension section 30 after they are connected, the head end extension section 20, the main body 10 and the tail end extension section 30 successively enter the sleeve cavity 42 through the sleeve port 43, so that the head end extension section 20 reaches the top end of the tube body 41 and the end of the tube body 41 is flush with the end of the tail end extension section 30.

[0050] The top end of the outer sleeve 40 can be set to a closed state, and the head end extension section 20 is sleeved inside the tube body 41. It can also be designed to be an open state, and the extension head 23 of the head end extension section 20 is exposed in front of the outer sleeve 40.

[0051] That is, in this embodiment, the outer sleeve 40 may also have a through hole 44, which is disposed at the top of the tube body 41 to communicate with the outside, making installation easier. The through hole 44 is connected to the sleeve cavity 42, and the sleeve cavity 42 is connected to the outside through the through hole 44 and the sleeve port 43.

[0052] Those skilled in the art can understand that whether the top end of the outer sleeve 40 is in a closed state or an open state, it does not affect the sleeve connection of the outer sleeve 40 , and therefore, the setting of the through hole 44 is not limited to the present invention.

[0053] In addition, it is worth mentioning that when the penile implant prosthesis is not provided with the head end extension section 20 and the tail end extension section 30, that is, when only the main body 10 is provided, the thickness is also changed by the outer sleeve 40. Therefore, at this time, the outer sleeve 40 only needs to match the main body 10.

[0054] When it is necessary to connect multiple layers of the outer sleeve 40 to gradually change the size, the sizes of the multiple layers of the outer sleeve 40 must match each other. For example, the size of the innermost outer sleeve 40 is slightly larger than the size of the main body 10, the size of the second outer sleeve 40 is slightly larger than the size of the innermost outer sleeve, the size of the third outer sleeve 40 is slightly larger than the size of the second outer sleeve 40, and so on. In this way, it can be connected and removed intact and fit well, so as to better meet the use requirements.

[0055] The inner and outer walls of the main body 10, the head end extension section 20, the tail end extension section 30 and the outer sleeve 40 are all smooth, which is convenient for connection and separation. After being implanted in the body, it will not damage human tissue and will not cause discomfort.

[0056] The main body 10 includes a first connection portion 11 and a second connection portion 12, the head end extension section 20 includes a head end connection portion 21, and the tail end extension section 30 includes a tail end connection portion 31, wherein the first connection portion 11 and the head end connection portion 21 match, so that the head end extension section 20 can be detachably connected to the head of the main body 10 to extend the main body 10 from the head end; the second connection portion 12 matches the tail end connection portion 31, so that the tail end extension section 30 can be detachably connected to the end of the main body 10 to extend the main body 10 from the end.

[0057] The body 10 further includes an outer shell 13 and an inner core 14, wherein the inner core 14 is integrally connected to the outer shell 13 and is located inside the outer shell 13. The length of the inner core 14 is shorter than the length of the outer shell 13, that is, both ends of the inner core 14 are at a predetermined distance from the head end and the tail end of the outer shell 13, so that the first connecting portion 11 and the second connecting portion 12 are respectively arranged at the front end and the tail end of the outer shell 13.

[0058] Specifically, the shell 13 includes a shell front section 131, a shell middle section 132 and a shell rear section 133, wherein the shell middle section 132 is connected between the shell front section 131 and the shell rear section 132. The shell inner core 14 is disposed in the shell middle section 132, and the shell front section 131 and the shell rear section 132 are both solid structures and are respectively located at the front end and the rear end of the inner core 14. In other words, the shell 13 is integrally formed on the outside of the inner core 14 to form a solid body 10 together, which is conducive to ensuring the strength of the penis implant prosthesis.

[0059] The first connecting portion 11 and the second connecting portion 12 are respectively arranged on the front section 131 and the rear section 132 of the shell, so that the head end extension section 20 and the tail end extension section 30 are respectively detachably connected to the front end and the end of the shell 13, so that the head end extension section 20, the tail end extension section 30 and the main body 10 form an integral structure, that is, the penile implant prosthesis, to meet clinical application requirements.

[0060] In the present invention, the inner core 14 is in the shape of a cylinder, wherein the inner core 14 is not a cylindrical core, but a cylinder with gaps formed by a multi-layer mesh structure. That is to say, in order to ensure that the inner core 14 has a certain strength and toughness and can be bent arbitrarily, the inner core 14 is designed to be a multi-layer mesh overlapping.

[0061] The inner core 14 is preferably made of silver wire or steel wire, and the outer shell 13 is preferably made of materials such as silicone, which can ensure the strength of the penis implant and give it a certain toughness to facilitate repeated straightening and bending. On the one hand, the life of the penis implant can be extended and the failure rate can be reduced. On the other hand, after being implanted in the human body, it can make the erection and relaxation states more natural.

[0062] like Figure 4A and Figure 4BAs shown, according to the first preferred embodiment of the present invention, in this embodiment, the first connection part 11 and the head end connection part 21 are connected in a plug-in manner, and the second connection part 12 and the tail end connection part 31 are also connected in a plug-in manner, and both are detachable.

[0063] In this embodiment, the cross-section of the first connecting portion 11 is a "T"-shaped groove, having a first inlet channel 111 and a first fixed channel 112, wherein the first inlet channel 111 and the first fixed channel 112 are connected, and the first inlet channel 111 and the first inlet channel 112 are both circular, and the two are connected to form a mushroom-shaped connecting channel.

[0064] The first inlet channel 111 is longitudinally arranged at the front section 131 of the outer shell, and the first fixed channel 112 is transversely arranged at the front section 131 of the outer shell, that is, the first inlet channel 111 is located at the top of the outer shell 13 and extends toward the middle of the outer shell 13, the first fixed channel 112 is closer to the inner core 14, and the size of the first fixed channel 112 is larger than that of the first inlet channel 111.

[0065] The head end connection part 21 is also a mushroom-shaped structure, which matches the first connection part 11. The head end connection part 21 includes a head end entrance section 211 and a head end fixed section 212, wherein the head end entrance section 211 is a cylindrical structure, the size of the head end fixed section 212 is larger than the size of the head end entrance section 211, and the head end fixed section 212 is suitable for being compressed and can rebound. In other words, by squeezing the head end fixed section 212 so that it passes through the first entrance channel 111 and enters the first fixed channel 112, the head end fixed section 212 returns to its original shape and is then fixed to the first fixed channel 112, so that the head end extension section 20 is connected to the body 10. When the head end extension section 20 needs to be removed or replaced, just pull it outward with force.

[0066] As above, the cross-section of the second connecting portion 12 is a "T"-shaped groove, having a second inlet channel 121 and a second fixed channel 122, wherein the second inlet channel 121 and the second fixed channel 122 are connected, and the second inlet channel 121 and the second inlet channel 122 are both circular, and the two are connected to form a mushroom-shaped connecting channel.

[0067] The second inlet channel 121 is longitudinally arranged at the rear section 133 of the outer shell, and the second fixed channel 122 is transversely arranged at the rear section 133 of the outer shell, that is, the second inlet channel 121 is located at the end of the outer shell 13 and extends toward the middle of the outer shell 13, the second fixed channel 122 is closer to the inner core 14, and the size of the second fixed channel 122 is larger than that of the second inlet channel 121.

[0068] The tail end connection part 31 is also a mushroom-shaped structure, which matches the second connection part 12. The tail end connection part 31 includes a tail end entrance section 311 and a tail end fixed section 312, wherein the tail end entrance section 311 is a cylindrical structure, the size of the tail end fixed section 312 is larger than the size of the tail end entrance section 311, and the tail end fixed section 312 is suitable for being compressed and can rebound. In other words, by squeezing the tail end fixed section 312 to make it pass through the second entrance channel 121 and enter the second fixed channel 122, the tail end fixed section 312 is restored to its original shape and then fixed to the second fixed channel 122, so that the tail end extension section 30 is connected to the body 10. When the tail end extension section 30 needs to be removed or replaced, just pull it outward with force.

[0069] In addition, the head end extension section 20 also includes an extension body 22 and an extension head 23, wherein the extension head 23 is connected to one end of the extension body 22, wherein the extension head 23 gradually shrinks from the portion connected to the size of the extension body 22 to the other end, and finally forms a rounded conical structure. The head end entrance section 211 of the head end connecting portion 21 is connected to the other end of the extension body 22, wherein the size of the head end entrance section 211 is smaller than the size of the extension body 22, and the head end entrance section 211 is formed by extending outward from the middle of the extension body 22.

[0070] The size of the extension body 22 matches the size of the outer shell 13, so that when the head end connecting portion 21 is connected to the first connecting portion 11, the extension body 22 fits tightly with the front section 131 of the outer shell, so that a complete structure is formed between the head end extension section 20 and the main body 10.

[0071] The tail end extension section 30 is a cylindrical structure, and the size of the tail end extension section 30 matches the size of the outer shell 13, so that when the tail end connecting portion 31 is connected to the second connecting portion 12, the tail end extension section 30 fits tightly with the rear section 133 of the outer shell to form a complete structure.

[0072] In this embodiment, when a longer penis implant prosthesis is needed, the shorter head end extension segment 20 and / or the shorter tail end extension segment 30 can be replaced with the longer head end extension segment 20 and / or the shorter tail end extension segment 30; conversely, when a shorter penis implant prosthesis is needed, the longer head end extension segment 20 and / or the longer tail end extension segment 30 can be replaced with the shorter head end extension segment 20 and / or the shorter tail end extension segment 30.

[0073] When the thickness needs to be changed, it can be achieved by gradually putting on or removing one or more of the outer sleeves 40, wherein the thickness of the outer sleeve 40 can be selected according to actual conditions, and the number of the outer sleeves 40 that need to be put on can also be selected according to actual conditions.

[0074] It is worth mentioning that those skilled in the art can understand that, in the present invention, only the length of the head end extension section 20 can be changed, that is, the tail end extension section 30 can be omitted. In other words, the present invention can only include the body 10 and the head end extension section 20, and the thickness can be changed by the outer sleeve 40 that matches each other. To change the thickness, multiple outer sleeves 40 of the same thickness or different thicknesses can be sleeved, or only one can be sleeved, but it can be replaced with different thicknesses, which can also achieve the degree of changing the thickness and meet different needs.

[0075] In this embodiment, in order to ensure comfort, the outer shell 13, the extension body 22, the tail extension section 30 and the outer sleeve 40 are all implemented as cylindrical structures.

[0076] like Figures 5 to 6B The second preferred embodiment of the present invention is shown, which is improved on the basis of the above embodiment. In this embodiment, the penis implant prosthesis comprises a body 10A, a head end extension section 20A and a tail end extension section 30A, wherein the head end extension section 20A and the tail end extension section 30A are detachably connected to the body 10A to change the length of the body 10A, thereby allowing the length of the penis implant prosthesis to be adjusted.

[0077] On the basis of the first preferred embodiment, the connection mode between the head end extension section 20A, the tail end extension section 30A and the body 10A is modified. In this embodiment, the connection mode between the head end extension section 20A and the first connection part 11A is a snap connection, and the connection mode between the tail end extension section 30A and the second connection part 12A is a snap connection.

[0078] The main body 10A includes a first connecting portion 11A and a second connecting portion 12A, and also includes an outer shell 13A and an inner core 14A, wherein the inner core 14A is integrally arranged inside the outer shell 13A, and the first connecting portion 11A and the second connecting portion 12A are respectively arranged at the two ends of the outer shell 13A, so that the head end extension section 20A and the tail end extension section 30A are detachably connected to the two ends of the outer shell 13A.

[0079] Specifically, the outer shell 13A includes an outer shell front section 131A, an outer shell middle section 132A and an outer shell rear section 133A, wherein the inner core 14A is installed in the outer shell middle section 132A, the first connecting portion 11A is arranged in the outer shell front section 131A, and the second connecting portion 12A is arranged in the outer shell rear section 133A. In other words, the first connecting portion 11A and the second connecting portion 12A are respectively located at the reserved positions between the two ends of the inner core 14A and the outer shell 13A.

[0080] The head end extension section 20A includes a head end connecting portion 21A, and the head end connecting portion 21A is serrated to match the first connecting portion 11A.

[0081] The head end connection part 21A includes at least one head end connection tooth 211A and at least one head end connection groove 212A, and the first connection part 11A includes at least one first connection tooth 111A and at least one first connection groove 112A, wherein the shape and number of the head end connection tooth 211A are adapted to the first connection groove 112A, and the shape and number of the head end connection groove 212A are adapted to the first connection tooth 111A. The head end connection tooth 211A and the first connection tooth 111A are both suitable for being squeezed and deformed, and can rebound and restore the deformation. When the head end extension section 20A is connected to the body 10A or separated from the body 10A, the head end connection tooth 211A and the first connection tooth 111A can be squeezed, and can restore the deformation after the external force is lost.

[0082] The first connecting portion 11A is disposed in the middle of the housing front section 131A, and the first connecting teeth 111A and the first connecting grooves 112A are disposed on two opposite inner side walls of the housing front section 131A.

[0089] It is worth mentioning that the head end connecting teeth 211B and the head end connecting grooves 212B are arranged alternately in a certain order, and the first connecting teeth 111B and the first connecting grooves 112B are also arranged alternately in a certain order, and the head end connecting teeth 211B correspond to the first connecting grooves 112B, and the head end connecting grooves 212B correspond to the first connecting teeth 111B, so as to facilitate corresponding connection.

[0090] The tail end connecting portion 31B includes a plurality of tail end connecting teeth 311B and a plurality of tail end connecting grooves 312B, for example, four, and the second connecting portion 12B includes a plurality of second connecting teeth 121B and a plurality of second connecting grooves 122B, for example, four, wherein the shape and number of the tail end connecting teeth 311B are adapted to the second connecting grooves 122B, and the shape and number of the tail end connecting grooves 312B are adapted to the second connecting teeth 121B. Moreover, the tail end connecting teeth 311B and the second connecting teeth 121B are both suitable for being squeezed and deformed, and can rebound and recover the deformation, and when the tail end extension section 30B is connected to the body 10B or separated from the body 10B, the second connecting teeth 121B and the tail end connecting teeth 311B are both suitable for being squeezed and deformed.

[0091] The tail end connecting teeth 311B and the tail end connecting grooves 312B are arranged alternately in a certain order, and the second connecting teeth 121B and the second connecting grooves 122B are also arranged alternately in a certain order, so that the tail end connecting teeth 311B correspond to the second connecting grooves 122B, and the tail end connecting grooves 312B correspond to the second connecting teeth 121B, so as to facilitate corresponding connection.

[0092] In this embodiment, when the length of the penis implant prosthesis needs to be changed, the connection position between the head end connection portion 21B and the first connection portion 11B can be changed. Figure 8As shown, by changing the connection position, the overlapping length of the head end extension section 20B, the tail end extension section 30B and the main body 10B when connected is changed, thereby changing the overall length of the penile implant prosthesis.

[0093] When the overlapping length of the head end extension section 20B, the tail end extension section 30B and the body 10B is short after being connected, there will be a gap between the two, that is, part of the head end connection groove 212B and part of the tail end connection groove 312B will be exposed to the outside, which will reduce the strength of the penis implant prosthesis. At this time, the outer sleeve 40B is sleeved on the outside to increase the strength and size.

[0094] like Fig.10 The fourth preferred embodiment of the present invention is shown. In this embodiment, the length and thickness of the penile implant prosthesis are changed simultaneously by adjusting the length of the outer sleeve 40C, that is, the adjustment of the length and thickness is achieved by using multiple or replacing outer sleeves 40C of different lengths and thicknesses.

[0095] In this embodiment, the penile implant prosthesis includes a main body 10C and a head end extension section 20C, wherein the head end extension section 20C is suitable for being manufactured as an integral part with the main body 10C, and can also be detachably connected, and the length between the two can be adjusted or not, and it only needs to change the length of the outer sleeve 40C.

[0096] When the length of the penile implant prosthesis needs to be extended, the outer sleeve 40C is changed by sleeve-jointing the outer side of the main body 10C and the head end extension section 20C. The thickness and length of the outer sleeve 40C can be selected according to actual conditions, and multiple outer sleeves 40C can also be sleeved.

[0097] For example, when the extension needs to be changed, a longer outer sleeve 40C can be selected to increase the length. That is, the length of the outer sleeve 40C is greater than the length of the main body 10C and the head end extension section 20C after being connected, and the penile implant prosthesis is formed as a whole after being sleeved.

[0098] The penile implant prosthesis has certain strength and hardness, can be bent and straightened manually, and the bending angle is adjustable, thus meeting the clinical needs of different patients.
