Implanted urine control structure

Technical Field

Among them, the surgical treatment method for urinary incontinence is generally represented by an implanted artificial urethral sphincter technique, which generally comprises a urethral constraint device, a switch device, a connection device, etc., and in practical application, the urethral constraint device is difficult to be idealized in tightness adjustment during operation, which may cause urethral constraint to be too tight, thereby causing difficulty in urination, and if the urethral constraint device is loose, the problem of urine leakage still occurs, therefore, the biggest problem of the method is that the structure is complex, the operation steps are complicated, and the operation wound is large, which is not favorable for popularization and application of the technique.

Furthermore, non-surgical solutions to urinary incontinence have attempted to solve the problem in the form of urine collectors or extra-penile clamps, including solutions featuring penile clamp structures, openable and closable structures, urethral compression structures, or urine collection structures. However, these schemes are clamped on the penis body, so that human discomfort is easily caused, and unsmooth blood supply to the penis is caused even after long-term use, and the most critical problem is that the external shape of the male penis is changed violently under different conditions of different time, different temperature and the like, so that the ideal installation and urine control effects of similar clamping structures are difficult to achieve.

In order to make those skilled in the art better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application shall fall within the scope of the protection of the embodiments in the present application.

Referring to fig. 1A to fig. 1D, the implantable urinary catheterizing structure 1 of the present application is used for providing a urinary catheterizing function and a urination function, and mainly comprises a first holding element 101, a second holding element 102, and a locking element 103.

The first clamping assembly 101 has a first clamping body 104 and a first urethral clamping member 105 disposed on the first clamping body 104, and the second clamping assembly 102 includes a second clamping body 106 and a second urethral clamping member 107 disposed on the second clamping body 106. Referring to fig. 1D, the second clamping body 106 can move along the first direction D1 relative to the first clamping body 104 under the action of the first force, so that the first urethral clamping element 105 and the second urethral clamping element 107 approach each other, thereby clamping the urethra of the patient for urine control.

In the embodiment, the first clamping assembly 101 has a first handle 108, the second clamping assembly 102 has a second handle 109, and the first handle 108 and the second handle 109 cooperate with each other to provide a first acting force for a user. However, the first force may be applied by other methods.

In addition, the first and second

urethral holding members

105 and 107 are respectively disposed at the bottom of the first and second holding

bodies

104 and 106 and are distributed in a staggered manner. In one embodiment, as shown in fig. 1B, two first urethral holding members 105a,105B are disposed at the bottom of the first holding body 104, and a second urethral holding member 107 is disposed at the bottom of the second holding body 106, wherein the first urethral holding members 105a,112B and the second urethral holding member 107 are disposed in a staggered manner, so as to firmly hold the urethra of the patient. However, it is not limited thereto, and in practical applications, the number of the first urethral holding member 105 can be more than two, and the number of the second urethral holding member 107 can also be more than one, depending on the practical needs.

In addition, the second clamping body 106 can be moved relative to the first clamping body 104 in a second direction D2 opposite to the first direction D1, for example, under the action of elastic force (described in detail later), so as to move the first urethral clamping member 105 and the second urethral clamping member 107 away from each other, thereby releasing the urethra of the patient for urination.

The locking assembly 103 is configured to automatically switch to a locking state when the second clamping body 106 moves from the urination position (e.g., the position shown in fig. 2A) to the urine control position (e.g., the position shown in fig. 2B) along the first direction D1 to limit the second clamping body 106 from moving along the second direction D2, so as to position the second clamping body 106 at the urine control position, so that the first and second

urethral clamping members

105 and 107 can maintain the

urethra clamping member

105 and 107 in the urethra clamping state, thereby providing the urethra control operation.

In addition, the locking state of the locking assembly 103 can be released by the second force to allow the second clamping body 106 to return to the urination position from the urination control position along the second direction D2, so that the first and second

urethral clamping members

105 and 107 release the urethra of the patient to provide the urination operation of the urethra. In the embodiment, the locking assembly 103 is also provided with a release handle 110, and the first handle 108 and the release handle 110 are matched to provide a second acting force for a user. However, the second force may be applied by other methods.

Referring to fig. 1C, fig. 2A and fig. 2B, which respectively show the internal structure of the implantable urine control structure 1 according to the first embodiment of the present application (i.e. the cover plate 111 is removed). In another embodiment, the first holding body 104 further comprises a first receiving unit 112 and a second receiving unit 113, wherein the first receiving unit 112 is used for receiving the second holding body 106, and a first moving area defined by the urination position and the urination control position is defined in the first receiving unit 112, so that the second holding body 106 moves in the first moving area. As shown in fig. 1C, in the present embodiment, the first receiving unit 112 has a limiting opening 114 therein for installing the second urethral clamping member 112 of the second clamping body 111, so that the second urethral clamping member 112 moves between a first side 114a and a second side 114b of the limiting opening 114, and the limiting opening 114 and the second urethral clamping member 112 cooperate to define the first moving interval, thereby defining the moving range of the second clamping body 106 in the first receiving unit 112. In this embodiment, when the second urethral holding member 112 abuts against the first side 114a of the position-limiting opening 114, it corresponds to the aforementioned urine control position, and when the second urethral holding member 112 abuts against the second side 114b of the position-limiting opening 114, it corresponds to the aforementioned urination position.

The second receiving unit 113 is used for receiving the locking assembly 103, and a second moving interval defined by the first position and the second position is defined in the second receiving unit 113, so that the locking body 123 moves in the defined second moving interval. As shown in fig. 1C, in the present embodiment, the locking assembly 103 is provided with a limiting sliding groove 115, and a limiting post 116 is further disposed in the second accommodating unit 113, wherein the limiting post 116 is disposed in the limiting sliding groove 115 in a penetrating manner, and slides between the first side 115a and the second side 115b of the limiting sliding groove 115, so as to define the second moving region by means of the cooperation between the limiting post 116 and the limiting sliding groove 115, thereby limiting the moving range of the locking body 123 in the second accommodating unit 113. In the present embodiment, the first position corresponds to a position where the position-limiting pillar 116 abuts against the first side 115a of the position-limiting sliding groove 115, and the second position corresponds to a position where the position-limiting pillar 116 abuts against the second side 115b of the position-limiting sliding groove 115.

In another embodiment, the implantable urinary catheter 1 further comprises a first elastic element 117 and a second elastic element 118, wherein the first elastic element 117 is configured to provide a first elastic force between the first clamping body 104 and the second clamping body 106, and specifically, when the second clamping body 106 is moved from the urination position to the urination control position along the first direction D1 (i.e. the second clamping body 106 moves towards the direction approaching the first clamping body 104) by the first force, the first elastic component 117 is compressed and elastically deformed, when the first force is released and the locking assembly 103 is released from its locked state by the second force, the first elastic element 117 is used for providing a first elastic force to push the second clamping member 102 to move from the urine control position to the urine drainage position along the second direction D2 (i.e. the second clamping body 106 moves away from the first clamping body 104). In the embodiment, the first elastic element 117 includes two springs, which are respectively disposed in the two long slots of the first clamping body 104, but not limited thereto, the number of the springs and the positions of the springs included in the first elastic element 117 can be changed according to actual requirements.

A second elastic element 118 for providing a second elastic force between the first clamping body 104 and the locking element 103, specifically, when the locking element 103 is moved from the first position to the second position by the second force (i.e. the locking element 103 moves towards the direction approaching the first clamping body 104), the second elastic element 118 is pressed by the locking element 103 to generate elastic deformation; when the second force is released, the second elastic element 118 is used to provide the second elastic force to move the locking element 103 from the second position to the first position.

In addition, the first elastic element 117 and the second elastic element 118 may be, for example, a coil spring, or a rubber ring, but not limited thereto, and other types of elastic deformation elements may be suitable.

In an embodiment of the present invention, a second elastic element 118 may be disposed in the second receiving unit 113 for providing a second elastic force between the first clamping body 104 and the locking body 123.

Referring to fig. 1C, the second receiving unit 113 further includes a locking groove 119 having a releasing end 119a and a locking end 119b at two opposite sides, the locking groove 119 is designed to be gradually narrowed from the releasing end 119a to the locking end 119b, and one side of the locking groove 119 is communicated with the first receiving unit 112. In the present exemplary embodiment, the locking groove 119 is designed as a wedge groove.

The locking assembly 103 further includes a locking member 120 and an ejector member 121. The locking member 120 is movably disposed in the locking groove 119, and is communicated with the first receiving unit 112 via one side of the locking groove 119, such that a portion of a surface of the locking member 120 directly contacts a portion of a surface of the second clamping body 106 disposed in the first receiving unit 112.

Referring to fig. 2B, when the second clamping body 106 moves along the first direction D1 relative to the first clamping body 104, the locking member 120 in the locking groove 119 is driven to move to one side of the releasing end 119a and is maintained at the position of the releasing end 119 a; when the second clamping body 106 moves relative to the first clamping body 104 along the second direction D2, the locking member 120 in the locking groove 119 is driven to move together toward the locking end 119 b; and when the locking member 120 is located at or near the locking end 119b of the locking groove 119, since the inner space of the locking groove 119 becomes smaller, the locking member 120 will press the second clamping body 106 located in the first receiving unit 112, thereby restricting the second clamping body 106 from moving relative to the first clamping body 104 along the second direction D2.

The ejector 121 is disposed on the locking body 123 and extends from the locking end 119b into the accommodating space of the locking groove 119. Referring to fig. 2A, the pushing member 121 is used to push the locking member 120 located at the locking end 119b to the releasing end 119a when the locking assembly 103 is moved from the first position to the second position (i.e. when the locking assembly 103 moves towards the direction approaching the first clamping body 104) by the second acting force, and the space of the releasing end 119a is larger, so that the pressing force of the locking member 120 on the second clamping body 106 is reduced until all the pressing force is released, and the locking state of the locking assembly 103 is released.

In another preferred embodiment, a third elastic element 122 may be further disposed in the locking groove 119 for providing a third elastic force to move the locking member 120 in the locking groove 119 to one side of the locking end 119b, thereby providing a better locking effect. It should be noted that, the user may choose to dispose or not dispose the third elastic element 122 in the locking groove 119 according to the actual requirement.

It should be noted that, in the present application, the second elastic element 118 may also be directly disposed in the locking groove 119, and there is no need to additionally dispose an elastic element in the second accommodating unit 113, so that the second elastic element 118 disposed in the locking groove 119 provides a second elastic acting force between the first clamping body 104 and the locking member 120, and the locking member 120 in the locking groove 119 moves to one side of the locking end 119b, and the locking member 120 pushes the ejector 121, so as to achieve the purpose of returning the locking member 103 from the second position to the first position.

When urine control is required, a first force is applied to move the second clamping body 106 relative to the first clamping body 104 along the first direction D1 (i.e. towards the first clamping body 104), so that the first urethral clamping member 105 and the second urethral clamping member 107 approach each other, and at the same time, the first elastic element 117 is pushed by the second clamping body 106 to be compressed, thereby generating elastic deformation.

When the second holding body 106 moves from the urination position to the urination control position, the first acting force can be released, and at this time, the second holding body 106 will be subjected to the first elastic acting force of the first elastic element 117 and tend to move along the second direction D2, which will drive the locking member 120 in contact with the second holding body to move towards the locking end 119b of the locking groove 119, so as to press the second holding body 106 in the first accommodating unit 112, so as to restrict the second holding body 106 from moving relative to the first holding body 104 along the second direction D2, so as to position the second holding body 106 at the urination control position, so that the first urethra holding member 105 and the second urethra holding member 107 are maintained at the state of holding the urethra for urination control.

When urination is required, a second acting force can be applied to push the locking body 123 to move from the first position to the second position (i.e. to move in a direction approaching the first clamping body 104), at this time, the second elastic element 118 is compressed and the pushing member 121 of the locking body 123 pushes the locking member 120 to the releasing end 119a of the locking groove 119, so that the locking state of the locking element 103 is released, thereby allowing the second clamping body 106 to move in the second direction D2 under the action of the first elastic force of the first elastic element 117, so as to move from the urination control position to the urination position, so that the first urethra clamping member 105 and the second urethra clamping member 107 move away from each other, thereby releasing the urethra for urination.

After urination is completed, the second acting force can be released, so that the locking body 123 returns from the second position to the first position under the action of the second elastic force of the second elastic element 118, and the acting force of the ejector 121 on the locking member 120 is released, so that the locking member 120 can be automatically switched to the locking state in the subsequent operation process. Therefore, the implantable urine control structure 1 provided by the first embodiment of the present application can provide a better urine control effect, and has the advantage of less implantation trauma.

Please refer to fig. 3, fig. 4A and fig. 4B, which respectively show schematic diagrams of the implantable urinary catheter structure 2 according to the second embodiment of the present application.

As shown in fig. 3, the implantable urinary catheter structure 2 according to the second embodiment of the present invention has substantially the same structure as that of the first embodiment, and is also mainly composed of a first holding component 201, a second holding component 202, and a locking component 203. Except that the first elastic member 217 of the present embodiment is a constant force spring.

Referring to fig. 4A and fig. 4B, they respectively show the internal structural diagrams of the implantable urine control structure 1 according to the second embodiment in different states (i.e. the internal structural views after removing the cover 211 of the first holding body 204).

As shown, when urine control is required, a first force is applied to move the second clamping body 206 relative to the first clamping body 204 along the first direction D1 (i.e. towards the first clamping body 204), so that the first urethral clamping member 205 and the second urethral clamping member 207 approach each other, and the constant force spring 217 is pushed by the second clamping body 206 and is stretched, thereby generating elastic deformation. When the second clamping body 206 moves from the urination position to the urination control position, the first acting force can be released, at this time, the second clamping body 206 is acted by the first elastic acting force of the constant force spring 217 and tends to move along the second direction D2, which drives the locking member 220 in contact with the second clamping body to move towards the locking end 219b of the locking groove 219 to press the second clamping body 206 in the first accommodating unit 212, and since the friction force between the locking member 220 and the second clamping body 206 is much greater than the first elastic acting force of the constant force spring 217, the second clamping body 206 can be limited from moving relative to the first clamping body 204 along the second direction D2, so that the second clamping body 206 is positioned at the urination control position, and the first urethra clamping member 205 and the second clamping member 207 are maintained in the clamped state to control the urethra.

Similarly, when urination is required, a second force can be applied to push the locking body 223 to move from the first position to the second position (i.e. to move in a direction approaching the first clamping body 204), the second elastic element 218 is elastically deformed, the pushing member 221 of the locking body 223 can push the locking member 220 to the releasing end 219a of the locking groove 219, so that the locking state of the locking element 203 is released, and the second clamping body 206 is allowed to move in the second direction D2 under the action of the first elastic force of the constant force spring 217 to move from the urination control position to the urination position, so that the first urethra clamping member 205 and the second urethra clamping member 207 move away from each other to release the urethra for urination.

Compared with the first embodiment, in the present embodiment, by using the constant force spring, since the deformation stroke of the constant force spring is smaller than that of the ordinary coil spring, the internal structure layout of the implanted urine control structure 2 can be more compact, so as to facilitate reducing the overall volume of the implanted urine control structure 2.

In addition, in the implantable

urine control structure

1,2 provided by the present application, the second clamping bodies 106,206 and the locking bodies 123,223 may be disposed on the same side of the first clamping bodies 104,204, or on two opposite sides of the first clamping bodies, respectively, so as to effectively avoid the occurrence of misoperation.

The first clamping assembly 301, the second clamping assembly 302 and the locking assembly 303 are also respectively provided with a first handle 308, a second handle 309 and a release handle 310, and the first handle 308, the second handle 309 and the release handle 310 are respectively provided with openings so as to facilitate the clamping operation of a user, meanwhile, the second handle 309 and the release handle 310 are respectively positioned at two opposite sides of the first clamping body 304, and the structural design can effectively prevent the occurrence of misoperation.

In the embodiment, the locking body 323 of the locking assembly 303 is movably connected to the release handle 310 through the connection column 324, and the release handle 310 is disposed between the two first handles 308 and is coupled to the first handles 308 at two sides through the connection shaft 325.

The first clamping body 304 further has a first receiving unit 312 and a second receiving unit 313 for receiving the second clamping body 306 and the locking body 323, respectively, and in the embodiment, a portion of the first receiving unit 312 and a portion of the second receiving unit 313 in the first clamping body 304 are integrated in space. The first accommodating unit 312 and the second accommodating unit 313 are further respectively provided with a first elastic component 317 and a second elastic component 318.

Furthermore, the second receiving unit 313 further includes a locking groove 319 (as shown in fig. 6A and 6B), please refer to fig. 5B, 5D and 5E, wherein fig. 5E is a side view of the cover 311 shown along the sectional line a-a of fig. 5D, the position of the cover 311 of the present embodiment corresponding to the locking groove 319 in the second receiving unit 313 further includes a limiting structure 328, such as a groove body with a protrusion and an inclined surface formed on the cover 311, when the cover 311 is covered on the first clamping body 304, the limiting structure 328 can be engaged with the second receiving unit 313 to form a wedge-shaped limiting groove 319 in the second receiving unit 313, and one side of the limiting groove 319 is communicated with the first receiving unit 312.

The locking assembly 303 further includes a locking member 320 (e.g., a ball) disposed in the locking slot 319, and an ejector 321 extending from the locking end 119b of the locking slot 319 into the receiving space of the locking slot 319. Under normal conditions, the pushing element 321 does not contact the locking element 320 (ball) in the locking groove 319 under the second elastic force of the second elastic element 318.

Please refer to fig. 6A and fig. 6B, which respectively show the internal structural diagrams of the implantable urine control structure 3 according to the third embodiment of the present application in different states (i.e. the internal structural views after removing the cover plate 311 of the first clamping body 304).

As shown, when urine control is required, a first force is applied to move the second clamping body 306 relative to the first clamping body 304 along the first direction D1, the first urethral clamping member 305 and the second urethral clamping member 307 approach each other, and the first elastic member 317 is compressed by the compression of the second clamping body 306, thereby being elastically deformed.

When the second holding body 306 moves from the urination position to the urination control position, the first acting force can be released, and at this time, the second holding body 306 will be acted by the first elastic force of the first elastic component 317 to have a tendency to move along the second direction D2, which will drive the locking member 320 in contact with it to move toward the locking end 319b of the locking slot 319, so as to press the second holding body 306 located in the first accommodating unit 312, so as to restrict the second holding body 306 from moving relative to the first holding body 304 along the second direction D2, thereby positioning the second holding body 306 at the urination control position, so that the first urethra holding member 305 and the second urethra holding member 307 are maintained at the state of holding the urethra for urination control.

When urination is required, a second acting force can be applied to the release handle 310, so that the release handle 310 drives the locking body 323 to move from the first position to the second position, and the pushing member 321 of the locking body 323 pushes the locking member 320 to the release end 319a of the locking groove 319, so that the locking state of the locking assembly 303 is released (as shown in fig. 6B), and the second clamping body 306 is allowed to move along the second direction D2 under the action of the first elastic force of the first elastic element 317 to move from the urine control position to the urination position, so that the first urethra clamping member 305 and the second urethra clamping member 307 move away from each other to release the urethra for urination.

Therefore, the implantable urine control structure 3 according to the third embodiment of the present application has an advantage that the second handle 309 and the release handle 310 are respectively disposed on two opposite sides of the first clamping body 304, so that the occurrence of misoperation can be effectively prevented. Furthermore, the locking body 323 of the locking assembly 303 is movably connected with the release handle 310 through the connecting column 324, and the locking body 323 can be horizontally displaced by turning over the release handle 310, so that the user can conveniently operate the locking assembly. In addition, the first urethra holding member 305 and the second urethra holding member 307 are respectively provided with a limiting part 327, so that the urethra is prevented from slipping off.

With reference to fig. 7A and 7B, fig. 8A and 8B are schematic structural diagrams respectively illustrating different embodiments of an implantable urine control structure 4 according to a fourth embodiment of the present application, wherein fig. 8A and 8B are schematic structural diagrams illustrating the implantable urine control structure 4.

As shown in the drawings, the implantable urinary catheter structure 4 according to the fourth embodiment of the present invention is also mainly composed of a first holding component 401, a second holding component 402, and a locking component 403. The first clamping component 401 has a first clamping body 404 and a first urethra clamping member 405 disposed on the first clamping body 404, the second clamping component 402 has a second clamping body 406 and a second urethra clamping member 407 disposed on the second clamping body 406, and the second clamping body 406 and the locking body 423 are respectively located at two sides of the first clamping body 404, that is, the second handle 409 and the release handle 410 are respectively located at two opposite sides of the first clamping body 404, and the second handle 409 is located at the same side of the first handle 408, so as to prevent the occurrence of misoperation.

In addition, the first clamping body 404 further has a first receiving unit 412 and a second receiving unit 413 for receiving the second clamping body 406 and the locking body 423, respectively, and in the embodiment, a portion of the first receiving unit 412 and a portion of the second receiving unit 413 in the first clamping body 404 are integrated in a space. A first elastic element 417 is disposed in the first accommodating unit 412, and is also used for providing a first elastic force between the first clamping body 404 and the second clamping body 406. Specifically, when the second clamping body 406 is moved from the urination position to the urination control position along the first direction D1 by the first acting force, the first elastic member 417 is elastically deformed, when the first acting force is released, the first elastic member 417 maintains the elastically deformed state, and when the locked state of the locking member 403 is released, the first elastic member 417 is used for providing the first elastic acting force to push the second clamping member 402 to move from the urination control position to the urination control position along the second direction D2.

In this embodiment, the second clamping body 406 further includes a segmented adjusting unit 430, on which a first stopping portion 431 and a second stopping portion 432 are disposed. Preferably, the segmented adjusting unit 430 further has at least one third stopping portion 439 located between the first stopping portion 431 and the second stopping portion 432, so as to provide multi-level segmented adjusting function. In the present embodiment, the segment adjusting unit 430 may be designed as a rectangular tooth structure formed on the second clamping body 406.

The locking assembly 403 further includes an ejector 421, a locking member 420, and a torsion spring 418, wherein the ejector 421 is disposed on the locking body 423 and extends from the second accommodating unit 413 to the first accommodating unit 412. The locking member 420 is rotatably disposed in the first accommodating unit 112 by the first locking column 433, and has a first end 434 and a second end 435, wherein the first end 434 can be engaged with the first stopping portion 431 or the second stopping portion 432 of the segment adjusting unit 430, and the second end 435 abuts against the pushing member 421.

The torsion spring 418 is rotatably disposed in the first accommodating unit 412 of the first clamping body 404 by the second locking column 436, and has a third end 437 and a fourth end 438, wherein the third end 437 is used for providing a fourth elastic force to the first end 434 of the locking member 420, so that the first end 434 of the locking member 420 is clamped in the first stopping portion 431 or the second stopping portion 432, and the fourth end 438 abuts against a specific position in the first accommodating unit 412, for example, the fourth end 438 of the torsion spring 418 abuts against a sidewall of the first accommodating unit 412, so that the third end 437 of the torsion spring 418 abuts against the first end 434 of the locking member 420.

When the second holding body 406 is located at the urination position, the first end 434 of the locking member 420 is engaged with the first stopping portion 431 under the fourth elastic force of the third end 437 of the torsion spring 418, and the locking assembly 403 is located at the first position of the second accommodating unit 113 (i.e., the pushing member 421 of the locking assembly 403 does not generate a pushing force on the second end 435 of the locking member 420).

When a first acting force is applied to the second clamping body 406 to move the second clamping body 406 from the urination position to the urination control position along the first direction D1 (i.e. the second clamping body 406 and the first clamping body 404 approach each other), since the segmented adjusting unit 430 on the second clamping body 406 moves towards the direction approaching the first clamping body 404, the segmented adjusting unit 430 with the rectangular tooth structure will toggle the first end 434 of the locking member 420 to drive the locking member 420 to rotate relative to the first clamping body 404 (in this embodiment, the locking member 420 can rotate counterclockwise relative to the first clamping body 404), so that the first end 434 of the locking member 120 moves from the first stopping portion 431 to the second stopping portion 432 (or from the first stopping portion 431 to the third stopping portion 439, and then moves from the third stopping portion 439 to the second stopping portion 432), and engages with the second stopping portion 432 (or the third stopping portion 439) under a fourth elastic acting force of the third end 437 of the torsion spring 418, thereby causing progressive approximation between the first urethral holding element 305 and the second urethral holding element 307 until the urethra is pinched or bent to provide the urine control function. In this state, the first elastic member 417 disposed in the first accommodating unit 412 is compressed to generate elastic deformation.

When the first acting force is released, since the second end 435 of the locking element 420 cannot reversely rotate relative to the first clamping body 404 under the abutting action of the pushing element 421 (i.e. the locking element 420 cannot rotate clockwise relative to the first clamping body 404), the first end 434 of the locking element 420 is limited to be maintained in the currently engaged second stopping portion 432 (or third stopping portion 439), so that the second clamping body 406 is prevented from moving in the second direction D2 under the action of the first elastic element 417, so as to position the second clamping body 406 at the current urine control position, and the first urethra clamping element 405 and the second urethra clamping element 407 are maintained in the state of clamping the urethra for urine control.

When urination is required, a second force is applied to the locking assembly 403 to move the locking assembly from the first position to the second position, so that the pushing member 421 of the locking assembly 403 pushes the second end 435 of the locking member 420, and the first end 434 of the locking member 420 is driven to disengage from the second stopping portion 432 (or the third stopping portion 439), so that the second clamping body 406 is moved from the urination control position to the urination position along the second direction D2 by the first elastic force provided by the first elastic member 417, and the first urethra clamping member 405 and the second urethra clamping member 407 move away from each other to release the urethra for urination.

Therefore, the implantable urinary catheter structure 4 according to the fourth embodiment of the present application has an advantage of providing the second holding body 406 to move relative to the first holding body 404 in a segmented manner by the structural design of the segmented adjusting unit 430, so as to meet different requirements of users.

In conclusion, the implantable urine control structure provided by the application can well solve the problem of urinary incontinence, and has the advantages of small implantation wound and ideal urine control effect. In addition, in one embodiment, by using different element configurations, for example, by using a constant force spring, the internal structure layout of the implantable urine control structure can be made more compact, which is beneficial to reduce the overall volume of the implantable urine control structure. In other embodiments, the second clamping body and the locking assembly can be disposed on two opposite sides of the first clamping body, so as to effectively prevent misoperation. In addition, in another embodiment, a sectional adjusting structure design can be further provided to provide a sectional adjusting function so as to meet the use requirements of different users.

Finally, it should be noted that: the above embodiments are only used for illustrating the technical solutions of the embodiments of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions in the embodiments of the present application.
