Description

Technical Field

[0001] The utility model relates to the field of erectile dysfunction treatment, and particularly relates to an adjustable penile implant device. Background Technique

[0002] The definition of erectile dysfunction (ED) is that the penile erection hardness during sexual life is insufficient to insert into the vagina or the erection maintenance time is insufficient to complete a satisfactory sexual life. Research shows that the incidence of ED is 52% in men aged 40 - 70 years old, showing an increasing trend with age, and about 25% in men under 40 years old. Besides psychogenic ED, organic ED caused by pathological changes in the brain - spinal cord - peripheral nerves accounts for 50%, and organic ED caused by pathological changes such as damage to the penile cavernous blood vessels, endothelial cells, nerves, and extracellular matrix is related to various chronic diseases such as aging, diabetes, cardiovascular diseases, obesity, trauma, surgery, and drug use.

[0003] ED can be classified into mild, moderate, and severe. The current ED treatment methods include first - line treatment with oral phosphodiesterase type 5 inhibitors, second - line treatment with intracavernous injection therapy, and artificial negative pressure device therapy as a one - time treatment method before sexual life. The effective rate for mild and moderate ED is 70%, and it has poor effect on severe ED. For those ineffective in the first - line and second - line treatments, the third - line penile prosthesis implantation surgery is selected.

[0004] The current devices for penile prosthesis implantation surgery for severe ED include single - piece flexible prostheses, two - piece inflatable prostheses, and three - piece inflatable prostheses. The two - piece and three - piece inflatable prostheses not only have high prices, complex surgical implantations, but also have relatively high incidences of complications such as infection, erosion, and device failure, which are 10% and 15% respectively 5 years and 10 years after implantation. The single - piece flexible prosthesis has a simple surgical implantation method, price advantages, and a relatively low failure rate. The main problem is the discomfort caused by the pen - type hardness of the implant. Content of the Utility Model

[0041] An elastic member is abutted against one side of the distal end of the transmission slider, and the end of the elastic member away from the transmission slider is axially abutted against the inner wall of the receiving groove.

[0046] When the telescopic member is in the extended state, when the bending member is bent to a preset degree, the cable can pull the transmission slider to slide towards the distal end on the movable member until the locking member is unlocked. As a preferred solution of the present application, by continuously bending the bending member, the lips of adjacent bowl-shaped joints can be changed from line contact to point contact. At this time, a gap is generated between a pair of adjacent first spherical surfaces and second spherical surfaces, resulting in an increase in the length of the bowl-shaped joint, so as to push the first limiting member, the tensioning member, the first convex portion, the cable, and the second convex portion towards the distal end to pull the transmission slider. Since the telescopic member is in the extended state and the movable member and the fixed member are axially locked, therefore, the transmission slider can move relative to the movable member towards the distal end to drive the clamping block to rotate through the transmission member until the limit convex moves out of the card slot, realizing the unlocking of the fixed member and the movable member.

[0087] Combined Figure 1 and Figure 3 As shown in this embodiment, an axially extending sliding cavity 210 is provided on the fixed member 21. The distal side of the sliding cavity 210 is open, and the proximal end of the movable member 22 is slidably disposed within the sliding cavity 210;

[0088] A locking member 23 is provided between the movable member 22 and the sliding cavity 210. The locking member 23 is used to axially lock the movable member 22 in the extended position on the fixed member 21;

[0089] The telescopic member 2 further includes an elastic reset member 24. The elastic reset member 24 is used to drive the movable member 22 to retract and reset;

[0090] The telescopic member 2 further includes a pulling portion. The pulling portion is connected to the movable member 22. The pulling portion is used to transmit an external force to drive the movable member 22 to move.

[0091] The principle of the telescopic member 2 is: applying a force to the pulling portion to drive the movable member 22 to slide within the sliding cavity 210 until the locking member 23 locks the movable member 22 and the sliding cavity 210. At this time, the telescopic member 2 is in the extended state. After the locking member 23 is unlocked, the elastic reset member 24 drives the movable member 22 to retract and reset. At this time, the telescopic member 2 is in the retracted state. In this embodiment, the fixed member 21 is in the shape of a circular tube, the cross-section of the movable member 22 is circular, a plug is fixed to the proximal end of the fixed member 21, and a positioning locking projection is provided on the plug and embedded in the proximal end of the outer sheath 31.

[0092] In this embodiment, a radially inwardly extending retaining edge 2102 is provided at the opening end of the sliding cavity 210, and a position limiting step 221 corresponding to the retaining edge 2102 is provided on the movable member 22, and the retaining edge 2102 is used to prevent the position limiting step 221 from moving too far. Specifically, when the telescopic member 2 is in the extended state, the retaining edge 2102 and the position limiting step 221 are against each other.

[0093] In this embodiment, an elastic ring 222 is provided between the limiting step 221 and the retaining edge 2102. The elastic ring 222 is provided on the limiting step 221. The elastic ring 222 is used to prevent the limiting step 221 and the retaining edge 2102 from directly bumping against each other. Specifically, the elastic ring 222 is fixed on the limiting step 221.

[0094] In this embodiment, the locking member 23 includes a block 231 and an elastic pressing member 232. The block 231 is rotatably mounted on the movable member 22. A limiting clamping protrusion 2311 is provided at the block 231 away from the rotating end. The elastic pressing member 232 abuts against the block 231. A slot 2101 matching the limiting clamping protrusion 2311 is provided on the inner wall of the sliding cavity 210. When the movable member 22 moves until the limiting clamping protrusion 2311 is axially aligned with the clamping slot 2101, the elastic pressing member 232 is used to push the limiting clamping protrusion 2311 into the clamping slot 2101 to achieve axial locking. Specifically, the block 231 is arranged in mirror symmetry, and the clamping slots 2101 are arranged in pairs. The elastic pressing member 232 is a compression spring with two ends abutting against the inner sides of a pair of blocks 231. The corresponding block 231 is provided with a positioning slot for receiving the end of the elastic pressing member 232.

[0095] In this embodiment, the movable member 22 is provided with an axially sliding transmission slider 25, which is arranged on one side of the clamping block 231. The movable member 22 is provided with a receiving groove 220 for receiving the clamping block 231 and the transmission slider 25. The transmission slider 25 is connected to the pulling part, and the transmission slider 25 and the elastic reset member 24 are connected through a transmission member. The pulling part is used to transmit a force to move toward the distal end to the transmission slider 25.

[0096] When the telescopic member 2 is locked in the extended state, the transmission member is used to make the block 231 and the transmission slider 25 work in conjunction. When the transmission slider 25 moves toward the distal end on the movable member 22, the block 231 is driven to rotate until the limiting protrusion 2311 moves out of the slot 2101.

[0097] An elastic member 26 is abutted against one side of the distal end of the transmission slider 25 , and an end of the elastic member 26 away from the transmission slider 25 is axially abutted against the inner wall of the receiving groove 220 .

[0098] The pulling part extends into the receiving groove 220 and is connected to the transmission slider 25. An external force is sequentially transmitted to the movable member 22 through the pulling part, the transmission slider 25, and the elastic member 26 to drive the movable member 22 to move in the extending direction. The elastic member 26 is used to push the transmission slider 25 to reset on the movable member 22.

[0099] In this embodiment, a limiting chute 251 extending axially is provided on the transmission slider 25, and a limiting rod 2201 is provided on the receiving groove 220. The radial dimension of the limiting rod 2201 is adapted to the width of the limiting chute 251.

[0100] When in a state without external force, the transmission slider 25 is pressed by the elastic member 26 so that the distal end of the limiting chute 251 abuts against the limiting rod 2201. The limiting rod 2201 is used to position the transmission slider 25 on the movable member 22.

[0101] The sliding fit between the limiting rod 2201 and the limiting chute 251 can enable the transmission slider 25 to slide on the receiving groove 220. Specifically, the limiting rod 2201 is cylindrical, and the limiting chute 251 and the limiting rod 2201 are provided in pairs.

[0102] In this embodiment, in combination with Figure 3 , Figure 5 , Figure 6 , Figure 8 as shown, the transmission member is a connecting rod 27. One end of the connecting rod 27 is rotatably connected to the corresponding point A on the clamping block 231. A connecting rod chute 252 is provided on the transmission slider 25. The extending direction of the connecting rod chute 252 corresponds to the moving direction of the transmission slider 25 on the movable member 22. The end of the connecting rod 27 away from the clamping block 231 is rotatably arranged in the connecting rod chute 252. The rotation center of the connecting rod 27 in the connecting rod chute 252 corresponds to point B, that is, point B can slide in the limiting chute 251. The rotation connection point of the clamping block 231 on the movable member 22 is C. When the telescopic member 2 is locked in the extended state, a preset angle less than 180° is provided between the connecting lines CA and BA. When the telescopic member 2 is locked in the extended state, during the process of the transmission slider 25 moving towards the distal end, CA and BA will rotate towards the direction of being collinear until the limiting convex 2311 moves out of the card slot 2101. The connecting rod chute 252 is used to provide the moving space of point B during the process of the limiting convex 2311 entering the card slot 2101.

[0103] In combination with Figures 7 to 9 as shown, in this embodiment, the bending member 1 corresponds to the pulling part. The movable member 22 is axially connected to the second limiting member 15. The cable 12 axially penetrates into the receiving groove 220, and the second convex part 122 is installed on the transmission slider 25.

[0104] When the telescopic member 2 is in the extended state, the bending member 1 is bent to a preset degree, and the rope 12 can pull the transmission slider 25 to slide toward the distal end on the movable member 22 until the locking member 23 is unlocked.

[0105] Continuously bending the bending member 1 can change the lip 113 of the adjacent bowl-mounted joint 11 from line contact to point contact. At this time, a gap is generated between a pair of adjacent first spherical surfaces 111 and second spherical surfaces 112, resulting in a lengthened length of the bowl-mounted joint 11, so as to push the first limiter 13, the tensioner 14, the first convex portion 121, the rope 12, and the second convex portion 122 toward the distal end, thereby pulling the transmission slider 25. Since the telescopic member 2 is in an extended state, the movable member 22 and the fixed member 21 are axially locked. Therefore, the transmission slider 25 can move toward the distal end relative to the movable member 22, so as to drive the block 231 to rotate through the transmission member until the limit convex 2311 moves out of the slot 2101, thereby unlocking the fixed member 21 and the movable member 22. In this embodiment, the elastic member 26 is used to provide pressure for the bowl-mounted joint 11 to fit tightly. To ensure that the shape of the bending member 1 is stable after bending. When the telescopic member 2 is switched from shortening to elongating, the bending member 1 can be bent by pulling and bending.

[0106] Combination Figure 4 As shown, in this embodiment, the elastic reset member 24 is a tubular sleeve, and the elastic reset member 24 is sleeved on the outside of the fixed component 21. One end of the elastic reset member 24 is fixed to the proximal end of the outside of the fixed component 21, and the other end of the elastic reset member 24 is sleeved and fixed on the outside of the movable component 22. Corresponding to the elastic reset member 24, a connecting outer edge 151 for fixing the elastic reset member 24 is provided on the movable component 22.

[0107] Therefore, the elastic reset member 24 also plays the role of the inner sheath of the telescopic member 2. In this embodiment, the connecting outer edge 151 is arranged on the second limiter 15, that is, the end of the elastic reset member 24 away from the fixed member 21 is sleeved and fixed on the second limiter 15. In other embodiments, the connecting outer edge 151 can be directly arranged on the movable member 22. The material of the elastic reset member 24 is elastic silicone.
