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.

Fig. 1A and 1B are schematic overall structural diagrams of an implantable urine control structure 1 according to a first embodiment of the present application, where fig. 1A is a schematic diagram showing a state in which a urine control component 11 is restrained, and fig. 1B is a schematic diagram showing a state in which the urine control component 11 is released. The implantable urinary catheterizing structure 1 of the present application can be implanted in a patient for providing the patient with urinary catheterizing and urination functions, and as shown in the figure, it mainly includes a urinary catheterizing component 11 and a control component 13. Wherein the urine control assembly 11 is fixed on the urethra of the patient and can be switched between a binding state (as shown in fig. 1A) and a releasing state (as shown in fig. 1B), and the control assembly 13 is connected to the urine control assembly 11 and is used for controlling the urine control assembly 11 to be switched between the binding state and the releasing state. Specifically, when the urine control assembly 11 is in a restrained state under the control of the control assembly 13, the urethra of the patient can be deformed (e.g. bent) for urine control; when the urine control assembly 11 is released under the control of the control assembly 13, the urethra of the patient can be restored to the original shape, so that the patient can urinate.

The urine control assembly 11 further comprises a urine control body 111 and an adjusting member 113, wherein the urine control body 111 has a urethra containing body 112, and a part of the urethra of the patient can be disposed in the urethra containing body 112, so that the urine control assembly 11 can be integrally positioned on the urethra of the patient. The adjusting member 113 can move relative to the urine control body 111 to switch between a bound state and a released state, so as to deform or restore the urethra accommodated in the urethra accommodating body 112 for carrying out the operation of urine control or urination.

In one embodiment, the adjusting element 113 is used for adjusting the accommodating urethra container 112 to deform the accommodating urethra container 112, so as to form a urine control accommodating space or a urination accommodating space inside the accommodating urethra container 112. Wherein, when the urethra containing body 112 forms the urine control containing space therein, the urethra contained in the urethra containing body 112 can be deformed to control urine; when the urethral containing body 112 forms a urination containing space therein, the urethra contained in the urethral containing body 112 can be restored to its original shape for urination.

In another embodiment, the adjusting member 113 can be moved relative to the urethral accommodating body 112 to deform or restore the urethra accommodated in the urethral accommodating body 112.

Specifically, please refer to fig. 1A and 1B, and fig. 2A and 2B. In this embodiment, the accommodating urethra container 112 includes an accommodating channel 1120 for accommodating a part of the urethra of the patient therein, wherein the accommodating channel 1120 is a half-open accommodating space and has a fixed side (i.e. the bottom of the accommodating channel 1120 shown in fig. 1A) and an open side (i.e. the top of the accommodating channel 1120 shown in fig. 1A), and a first buckling portion 1121 and a second buckling portion 1122 for buckling the urethra in the accommodating channel 1120 are further formed at two ends of the open side of the accommodating channel 1120, and a buckling direction of the first buckling portion 1121 is opposite to a buckling direction of the second buckling portion 1122, so as to achieve a better buckling effect, so that the urethra can be firmly positioned in the accommodating channel 1120 and is not easily dropped. However, it is not limited thereto, the first latching portion 1121 and the second latching portion 1122 can be designed to have the same latching direction (as shown in fig. 3).

In addition, a groove 1123 is formed at a middle position of the fixed side of the receiving channel 1120 (i.e., the bottom of the receiving channel 1120 shown in fig. 1A), wherein the adjusting member 113 can be received in the groove 1123 without affecting the urethra in the receiving channel 1120, or the adjusting member 113 can extend out of the groove 1123 into the receiving channel 1120 to press the urethra in the receiving channel 1120. In addition, in the embodiment shown in fig. 1A, 1B, 2A and 2B, the adjusting member 113 is formed with an arc-shaped contact surface which is adapted to the external shape of the urethra, so as to achieve better control effect. However, it is not limited thereto, and the adjusting member 113 may also be designed to be a pushing structure as shown in fig. 3, fig. 4A and fig. 4B or other structural shapes.

Referring to fig. 1A and fig. 2A in combination, when urine control is needed, the adjusting element 113 can extend out from the groove 1123 and into the accommodating channel 1120, in this state, the adjusting element 113 presses the urethra in the accommodating channel 1120 upwards from the middle position of the bottom of the accommodating channel 1120, and since the first buckling part 1121 and the second buckling part 1122 are respectively located at the two ends of the accommodating channel 1120, the middle section of the urethra arches upwards under the pressing action of the adjusting element 113 to deform, so as to achieve the purpose of urine control.

With continued reference to fig. 1B and fig. 2B, when urination is required, the adjusting member 113 can be retracted from the containing channel 1120 and received in the groove 1123, and in this state, the pressing force exerted by the adjusting member 113 on the urethra is released, so that the arched middle portion of the urethra is restored to its original shape for urination.

The control assembly 13 includes a control body 131, a state control member 132, and a state maintaining member 133 (see fig. 2A and 2B).

The control body 131 defines a urine control position (located at the top of the control body 131 shown in fig. 2A), a urination position (located at the bottom of the control body 131 shown in fig. 2A), and a movement range defined by the urine control position and the urination position.

The state control member 132 is connected to the adjusting member 113 of the urine control assembly 11, and can move relative to the control body 131 within a moving range defined by the urine control position and the urination position, so as to control the adjusting member 113 to switch between the restrained state and the released state.

The implantable urinary control structure 1 may further comprise a connecting assembly 12 for connecting the urinary control assembly 11 and the control assembly 13, respectively, wherein the connecting assembly 12 is preferably deformable, flexible and capable of force transmission in the axial direction. In the present application, the connecting component 12 may be made of a material capable of axially transmitting force and deforming, such as a polymer tube, a braided tube, or a spring tube, and is suitable for being disposed in a patient. A linking structure is further disposed inside the connecting component 12, and is respectively connected to the adjusting component 113 and the status control component 132, so that the adjusting component 113 can be linked with the status control component 132.

In one embodiment, the linking structure of the present application uses a mechanical principle to link the adjusting member 113 with the state control member 132. Specifically, as shown in fig. 2A and 2B, in the present embodiment, the connection assembly 12 further includes a sheath 121 and a mandrel 122 disposed inside the sheath 121 to serve as a linking structure, wherein both the sheath 121 and the mandrel 122 can be made of soft material, both ends of the sheath 121 are respectively connected to the urine control body 111 and the control body 131 of the urine control assembly 11, the mandrel 122 is movably disposed inside the sheath 121, and both ends of the mandrel 122 are respectively connected to the adjusting member 113 and the state control member 132, so that the adjusting member 113 can be linked with the movement of the state control member 132, in the present embodiment, when the state control member 132 is moved to the urine control position, the adjusting member 113 can be driven by the mandrel 122 to be switched to the binding state, so that the urethra accommodated in the urethra accommodating body 112 is deformed to control urine (as shown in fig. 2A), and when the state control member 132 is moved to the urination position, the adjusting member 113 is driven by the mandrel 122 to switch to a constrained state, so that the urethra accommodated in the urethra accommodating body 112 is restored to its original shape for urination (as shown in fig. 2B).

The status holding member 133 is used to position the status control member 132 in the urine control position. In the present application, the state maintaining member 133 can be implemented by various embodiments:

referring to fig. 2A and 2B, in an embodiment, the state retaining member 133 can achieve the above-mentioned positioning effect by using a magnetic attraction principle of a magnetic attraction component. Specifically, in the present embodiment, the control body 131 further has a receiving unit 130, and the receiving unit 130 defines a urine control position, a urine discharge position, and a movement range defined by the urine control position and the urine discharge position. In the embodiment shown in fig. 2A and 2B, the urine control position is defined at the top of the containing unit 130, and the urination position is defined at the bottom of the containing unit 130. The state control member 132 is disposed in the accommodating unit 130 and can move within the moving range of the accommodating unit 130; the status holder 133 is used to position the status control member 132 at the urine control position on the top of the housing unit 130.

As shown in fig. 2A, in a normal state, the first magnetic element 1331A and the second magnetic element 1331B are attracted to each other by a magnetic principle, so that the state control element 132 is positioned at the urine control position of the accommodating unit 130. The state control member 132 can be moved from the urination controlling position in the containing unit 130 to the urination position (as shown in fig. 2B) by applying a force to the state control member 132 for urination. In addition, when the acting force applied to the state control member 132 is released, the second magnetic element 1331B is attracted by the first magnetic element 1331A and moves toward the first magnetic element 1331A until the first magnetic element 1331A and the second magnetic element 1331B are attracted to each other, so that the state control member 132 returns to the urine control position from the urination position in the accommodating unit 130.
