Description

Technical Field

[0001] This disclosure relates to a buckle-type urethral occlusion device. This disclosure also relates to an internal device including the buckle-type urethral occlusion device for controlling urinary incontinence. Background Technology

[0002] Urethral occlusion devices have been used to treat urinary incontinence. In use, the urethral occlusion device is placed around the patient's urethra, and controls the flow of urine by selectively applying and releasing pressure on the urethra.

[0003] Existing urethral occluders require the connecting tube to be routed around the urethra and passed through an installation hole on the urethral occluder. The installation hole is then fitted onto a positioning structure on the urethral occluder and secured. Only then can the connecting tube be connected to other internal devices, such as pumps, used to control urinary incontinence and inflate the urethral occluder. This necessitates the surgeon to inflate the urethral occluder and control the inflation volume during the procedure, increasing the complexity and duration of the surgery. Furthermore, during the procedure, it is difficult to prevent blood from entering the urethral occluder, which can cause fluid blockage and lead to surgical failure. Summary of the Invention

[0004] In view of at least one of the deficiencies in the prior art, one of the objectives of this disclosure is to provide a buckle-type urethral occlusion device that can simplify surgical procedures and improve surgical success rates.

[0005] Therefore, in one aspect of this disclosure, a buckle-type urethral blocker is provided, the buckle-type urethral blocker including a connecting tube, a fluid-filled bladder, and a snap-fit ​​structure, the connecting tube being connected to the fluid-filled bladder for injecting liquid into the fluid-filled bladder and receiving liquid discharged from the fluid-filled bladder, characterized in that the snap-fit ​​structure includes a first snap-fit ​​portion and a second snap-fit ​​portion, the first snap-fit ​​portion being capable of engaging with the second snap-fit ​​portion such that the buckle-type urethral blocker is held in an engaged state around the urethra, and wherein the connecting tube is separately disposed from the first snap-fit ​​portion and the second snap-fit ​​portion.

[0006] In one configuration, the first latching part is a latching protrusion, and the second latching part is a latching hole.

[0007] In one configuration, the buckle-type urethral blocker further includes a flexible band, with the buckle protrusion and the buckle hole located at both ends of the flexible band, and the connecting tube located between the buckle protrusion and the buckle hole.

[0008] In one configuration, the fluid-filled bladder is disposed on one side of the flexible strip, and the snap-fit ​​protrusion and the connecting tube are disposed on the other side of the flexible strip opposite to the one side.

[0009] In one configuration, the flexible strip unfolds into a plane when the buckle protrusion is not engaged with the buckle hole.

[0010] In one configuration, the buckle-type urethral blocker is configured to be pre-filled with liquid before being installed around the urethra.

[0011] In one configuration, the latching protrusion is provided with a traction portion that facilitates gripping by the operator.

[0012] In one configuration, the traction part is designed to be removable.

[0013] In another aspect, an internal device for controlling urinary incontinence is provided, the internal device for controlling urinary incontinence comprising the buckle-type urethral blocker as described above.

[0014] In one configuration, the internal device for controlling urinary incontinence further includes a pump that remains connected to the connecting tube throughout the process of the button-type urethral blocker being installed around the urethra.

[0015] Because the connecting tube is separately configured from the first and second snap-fit ​​parts, the fluid passage within the snap-fit ​​urethral blocker remains closed throughout the installation process around the urethra. The fluid can be pre-filled into the snap-fit ​​urethral blocker during manufacturing, simplifying the surgical procedure and preventing blood from entering the blocker during surgery, thus improving the success rate. Furthermore, engineers can pre-fill and functionally adjust the internal components, including the urethral blocker, before surgery, allowing the surgeon to simply place the urethral blocker over the urethra during the procedure.

[0021] The present disclosure will now be described with reference to the accompanying drawings, which illustrate several embodiments of the present disclosure. However, it should be understood that the present disclosure can be presented in many different ways and is not limited to the embodiments described below; in fact, the embodiments described below are intended to make the disclosure more complete and to fully illustrate the scope of protection of the present disclosure to those skilled in the art.

For the sake of brevity and / or clarity, well-known functions or structures may not be described in detail.

[0023] The terms “comprising,” “including,” and “containing” used in the specification indicate the presence of the claimed feature, but do not exclude the presence of one or more other features. The term “and / or” used in the specification includes any and all combinations of one or more of the relevant listed items.

[0024] The use of the terms “connection,” “link,” “connected,” “associated,” or similar terms in the instruction manual is intended to indicate direct and / or indirect connections.

[0025] like Figure 1 As shown, the buckle-type urethral blocker according to this disclosure includes a connecting tube 1, a fluid-filled balloon 2, a snap-fit ​​structure, and a flexible band 5.

[0026] The inflatable bladder 2 can be made of silicone or any other suitable material. In use, the inflatable bladder 2 surrounds the patient's urethra 7 and is pressurized by the injection of liquid. When the inflatable bladder is pressurized, it clamps the patient's urethra 7, thereby closing the urethra; when the liquid in the inflatable bladder is expelled and the pressurization is released, the inflatable bladder relaxes the patient's urethra 7, thereby opening the urethra and allowing urine to drain from the urethra 7.

[0027] The connecting tube 1 is used to inject liquid into the filling bladder 2 and to receive liquid discharged from the filling bladder 2. One end of the connecting tube is connected to the filling bladder 2. Optionally, the connecting tube 1 can be connected to the filling bladder via the collection section 8. The other end of the connecting tube 1 (not shown) can be detachably connected to a device for supplying liquid to the buttonhole urethral blocker, such as a pump.

[0028] The snap-fit ​​structure includes a first snap-fit ​​portion and a second snap-fit ​​portion. The first snap-fit ​​portion can engage with the second snap-fit ​​portion. The first snap-fit ​​portion can be a snap-fit ​​protrusion 3. The second snap-fit ​​portion can be a snap-fit ​​hole 4. The first snap-fit ​​portion and the second snap-fit ​​portion can also be any other structure capable of engaging with each other. When the first snap-fit ​​portion and the second snap-fit ​​portion are engaged with each other, the snap-fit ​​urethral blocker can be held in the engaged state around the urethra 7, such as... Figure 2 As shown.

[0029] In the buckle-type urethral blocker of this disclosure, the connecting tube 1 and the optional collection section 8 are separately provided from the snap-fit ​​structure (i.e., the first snap-fit ​​section and the second snap-fit ​​section). In one configuration, the snap-fit ​​structure can be provided on the flexible band 5. The snap-fit ​​protrusion 3 and the snap-fit ​​hole 4 can be respectively provided at both ends of the flexible band 5. The connecting tube 1 and the optional collection section 8 can be provided between the snap-fit ​​protrusion 3 and the snap-fit ​​hole 4. With this arrangement, when wrapping the buckle-type urethral blocker around the urethra 7, it is not necessary to pass the connecting tube 1 through the snap-fit ​​hole 4 of the snap-fit ​​structure; instead, it is only necessary to pass the separately provided snap-fit ​​protrusion 3 through the snap-fit ​​hole 4 and snap them together. Thus, during the installation of the buckle-type urethral blocker of this disclosure, the other end (not shown) of the connecting tube 1 of the buckle-type urethral blocker can always be connected to other auxiliary devices (e.g., a pump for supplying fluid to it). Therefore, before the buckle-type urethral blocker of this disclosure is installed around the urethra 7, for example during the manufacture of the buckle-type urethral blocker of this disclosure, liquid can be filled into the filling sac of the buckle-type urethral blocker, and during the installation process, the liquid path of the buckle-type urethral blocker of this disclosure can always be kept isolated from the outside world, thus reducing the complexity of the operation during surgery and improving the success rate of the surgery by avoiding blood from entering the liquid path.

[0030] The flexible band 5 is formed of a material suitable for implantation in the human body. Specifically, the flexible band 5 can be made of a flexible material with a certain degree of elasticity. The flexible material can, for example, be formed of a combination of silicone and polymer materials. With this type of flexible material, the operator can easily wrap the buckle-type urethral blocker around the patient's urethra 7.

[0031] When the first snap fastener is not engaged with the second snap fastener, the buckle-type urethral blocker is in the deployed state. Figure 1As shown, in the unfolded state, the flexible band 5 can be formed as a plane. The filling bladder 2 can be disposed on one side of the flexible band 5. In one configuration, the filling bladder 2 extends along a portion of the length of the flexible band 5, allowing the operator's hand to easily grasp the flexible band for operation. A connecting tube 1 and an optional collection portion 8 can be disposed on the flexible band 5. In one configuration, the connecting tube 1 and the optional collection portion 8 can be disposed on the opposite side of the flexible band 5 from the side where the filling bladder is disposed. Thus, when the buckle-type urethral blocker is wrapped around the urethra 7, as... Figure 2 As shown, the inflatable balloon 2 can be positioned on the side in contact with the urethra 7, and the snap-fit ​​protrusion 3 and connecting tube 1 can be positioned on the side facing the operator, thus facilitating operation. During installation, the operator can face the side of the inflatable balloon 2 toward the patient's urethra 7, wrap the flexible band 5 around the patient's urethra 7, then pass the snap-fit ​​protrusion 3 through the snap-fit ​​hole 4 and fasten the two together, thereby obtaining the desired result. Figure 2 The image shows a buckle-type urethral blocker fitted around the urethra 7 and in a fastened state. It is evident that the buckle-type urethral blocker of this disclosure is simple and convenient to install, and during installation, there is no need to disconnect the other end (not shown) of the connecting tube 1 from other additional devices.

[0032] In one configuration, the latching protrusion 3 may be provided with a traction part 6 for easy gripping by the operator. The traction part 6 may be a traction post extending from the latching protrusion 3 or any structure that facilitates gripping by the operator. When engaging the latching protrusion 3 and the latching hole 4, the operator can grip the traction part, allowing the latching protrusion 3 to easily pass through the latching hole 4, which greatly facilitates the operator's operation.

[0033] The traction portion 6 is configured to be removable. For example, the traction portion 6 may be bonded, welded, or otherwise attached to the snap-fit ​​protrusion 3. After the snap-fit ​​urethral blocker is held in the engaged position around the urethra, the traction portion 6 may be cut off.

[0034] During the manufacturing process, the flexible belt 5, the liquid-filled bladder 2, the snap-fit ​​protrusion 3, the connecting tube 1, and the optional liquid collection part 8 can be molded into one piece through a molding process.

[0035] The working process of the buckle-type urethral occlusion device disclosed herein is as follows: Figure 3 and Figure 4 As shown. After the buckle-type urethral occlusion device is held in the buckled state around the urethra 7, if it is necessary to block the urethra 7, liquid can be further injected into the filling balloon 2 through the connecting tube 1 to increase the pressure in the filling balloon 2. In this case, as... Figure 3As shown, the inflatable balloon applies pressure to the urethra to clamp it, thereby blocking the flow of urine in the urethra; when it is necessary to release the urethral obstruction, the fluid in the inflatable balloon 2 can be allowed to flow out through the connecting tube 1 to reduce the pressure in the inflatable balloon 2. In this case, as... Figure 4 As shown, the inflatable bladder relieves the pressure on the urethra, thus relaxing the urethra and allowing urine to flow through it.

[0036] The urethral occluder disclosed herein can be used as a component of an in vivo device for controlling urinary incontinence. The in vivo device for controlling urinary incontinence is completely implanted within the patient's body and, in addition to the urethral occluder of this disclosure, may also include an energy and / or information transmission module, a controller, and additional components such as a pump for supplying fluid to the urethral occluder. Due to the structure of the urethral occluder of this disclosure, the pump and other external components can remain connected to the connecting tube throughout the installation of the snap-fit ​​urethral occluder around the urethra. This allows fluid to be filled into the urethral occluder through the connecting tube during the manufacture of the in vivo device, and the urethral occluder can maintain a closed fluid circuit isolated from the outside environment throughout the installation process. Thus, engineers can fill the in vivo device, including the urethral occluder, with fluid and perform functional adjustments before surgery, allowing the surgeon to simply place the urethral occluder over the urethra during the operation, greatly simplifying the surgical procedure and improving the success rate by preventing blood from entering the in vivo device.

[0037] Although only specific embodiments of this disclosure are illustrated and described herein, various modifications and variations will be apparent to those skilled in the art. Therefore, it should be understood that the appended claims are intended to cover all modifications and variations falling within the true spirit and scope of this disclosure.
