Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a catheter closure device. Background Technology

[0002] Catheter closure devices are well-known and commonly referred to as "artificial sphincters." They are placed in the body to assist or replace the body's own sphincters, helping patients with urinary incontinence caused by various neurological disorders, surgery, spinal cord injuries, etc., to regain the ability to control urination.

[0003] Existing catheter closure devices require the user to press down the plunger during urination. The plunger has barbs, and when the plunger is fully depressed, a bias rod with a locking mechanism in the control device locks with the barbs, keeping the closure mechanism in the open position until the user manually presses down the bias rod to release the barbs, returning the closure mechanism to the closed position. Existing catheter closure devices are complex in structure, and the user needs to manually press the bias rod to release the plunger, making operation inconvenient. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the purpose of this utility model is to provide a closure device for a catheter. The closure device has a locking element. When urinating, the user only needs to rotate the adjusting element to lock the adjusting element, thereby keeping the closure mechanism in the non-closed position. The structure is simple and easy for the user to operate.

[0005] The technical solution adopted by this utility model is: to provide a closure device for a catheter, comprising:

[0006] A closing mechanism, comprising a conduit portion and a flexible portion, the flexible portion surrounding the conduit and the flexible portion being used to apply a closing pressure to the conduit;

[0007] A control mechanism is connected to the closing mechanism via the pipe section. The control mechanism includes a driving member and a locking member. The driving member can drive the closing mechanism to a closed position and drive the closing mechanism to a non-closed position. The locking member can lock the driving member so that the closing mechanism remains in the non-closed position.

[0008] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The embodiment of this utility model provides a locking member, which can lock the driving member, so that the closed structure is kept in the non-closed position. The structure is simple and easy for users to operate.

[0009] In some embodiments, the driving member includes an adjusting member, a gear member, and a pulley member. Pushing the adjusting member can drive the gear member to move, and the movement of the gear member can drive the pulley member to move, so that the closing mechanism is in a non-closed position.

[0010] Compared with existing technologies, the technical effect achieved by adopting this technical solution is that when the user uses it, the user can drive the gear component to move by pushing the adjustment component, thereby driving the pulley component to move, so that the closing mechanism is in the non-closed position, which makes the operation simple.

[0011] In some embodiments, the adjusting member further includes a toothed ring, and the gap between adjacent toothed rings can cooperate with the teeth of the gear component. Pushing the toothed ring of the adjusting member can drive the gear component to move, so that the closing mechanism is in a non-closed position.

[0012] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The adjusting component includes a gear ring. When the user pushes the adjusting component, the gear ring engages with the gear component and rotates the gear component. The gear component rotates the pulley component counterclockwise. The engagement of the gear ring with the gear component drives the gear component to rotate in the opposite direction. The structure is simple.

[0013] In some embodiments, one end of the adjusting member extends out of the control mechanism, and the other end of the adjusting member is provided with a thread. The locking member includes a threaded hole, which is disposed opposite to the threaded end of the adjusting member. When the adjusting member is pushed to engage with the threaded hole, rotating the adjusting member can lock the adjusting member with the threaded hole, so that the closing mechanism is kept in the non-closed position.

[0014] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: a threaded hole is provided at the threaded end of the adjusting member, and the threaded hole can be matched with the thread on the adjusting member. The adjusting member can be locked by simply rotating the adjusting member to turn the thread into the threaded hole, and the closing mechanism can be kept in the non-closed state. The user does not need to press the adjusting member continuously when urinating.

[0015] In some embodiments, the pulley component has an offset member at its center. When the adjusting component is rotated to disengage from the threaded hole, the offset member enables the closing mechanism to return to the closed position.

[0016] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the setting of the biasing member not only applies an initial tension force to the closing mechanism, so that the closing mechanism is in the closed position in the initial state, but also, when the user rotates the adjusting member to disengage from the threaded hole after urinating, the adjusting member can return to the initial state under the influence of the biasing member, so that the closing mechanism returns to the closed position.

[0017] In some embodiments, the closure mechanism includes at least one suture cavity extending from the flexible portion to the tube portion, wherein a traction suture is provided within the suture cavity, the traction suture is connected to the control mechanism, and the traction suture can be driven by the control mechanism to a closed position and an unclosed position.

[0018] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the closing mechanism includes a suture cavity and a traction suture, and the traction suture extends from the flexible part to the pipe part, which enables the tension force applied by the control mechanism to be transmitted to the flexible part through the traction suture, facilitating the bending part to the closed position and the non-closed position.

[0019] In some embodiments, a connector is provided at a first end of the flexible portion away from the conduit portion, and a connection position is provided at a second end of the flexible portion, wherein the connector can be connected to the connection position, so that the flexible portion can surround the conduit.

[0020] Compared with the prior art, the technical effect achieved by adopting this technical solution is that the setting of the connector enables the curved part to be ring-shaped, thereby surrounding the conduit.

[0021] In some embodiments, the connector is further provided with a positioning member, which is detachably connected to the connector. The positioning member is used to help position the flexible portion against the outer surface of the conduit, so that the flexible portion can surround the conduit.

[0022] Compared with the prior art, the technical effect achieved by adopting this technical solution is that the positioning element can help position and keep the closing mechanism in place against the adjacent conduit and on the surface outside the conduit, so that the connector can connect to the connection position.

[0023] In some embodiments, the closing mechanism further includes a receiving cavity extending from the flexible portion to the pipe portion, wherein the receiving cavity within the pipe portion is provided with a rigid member for increasing the rigidity of the pipe portion.

[0024] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: the pipe section connects the control mechanism and the closing mechanism, and the rigid component inside the pipe section can improve the rigidity of the pipe section to prevent it from being flattened.

[0025] In some embodiments, the control mechanism is covered with a thin film that guides the solution into the control mechanism and the closing mechanism.

[0026] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the control mechanism is covered with a thin film, which allows drugs to be injected into the control mechanism and the closing mechanism via a syringe, and then flow into human tissues to exert their effects in the human body.

[0027] In summary, the above-mentioned technical solutions of this application can have one or more of the following advantages or beneficial effects: The closing device of this utility model has a locking component. When urinating, the user only needs to rotate the adjusting component to lock the adjusting component, thereby keeping the closing mechanism in the non-closed position. After urinating, the user only needs to rotate the adjusting component to return the adjusting component to the initial state, that is, the closing mechanism returns to the closed position. The closing device has a simple structure and is easy for the user to operate. Attached Figure Description

[0040] The following reference Figures 1 to 7 The technical solutions of some embodiments of this utility model are described below.

[0041] See appendix Figure 1 and attached Figure 2 As shown, the technical solution adopted by this utility model is: to provide a closure device for a catheter 300, comprising:

[0042] The closing mechanism 100 includes a conduit portion 120 and a flexible portion 110, the flexible portion 110 surrounding the conduit 300, and the flexible portion 110 being used to apply closing pressure to the conduit 300.

[0043] The control mechanism 200 is connected to the closing mechanism 100 via the pipe section 120. The control mechanism 200 includes a driving member and a locking member. The driving member can drive the closing mechanism 100 to a closed position and drive the closing mechanism 100 to a non-closed position. The locking member can lock the driving member so that the closing mechanism 100 is kept in the non-closed position.

[0044] Specifically, the closing mechanism 100 is a strip structure, which includes a flexible portion 110 and a conduit portion 120. The flexible portion 110 can completely or partially surround the conduit 300 in any way, as long as the conduit 300 can be closed or restricted.

[0045] Optionally, the closure mechanism 100 and the control mechanism 200 are integrally formed and do not need to be installed during surgery. The closure device can be implanted into the male or female body.

[0046] See appendix Figure 2 As shown, in some embodiments, the driving member includes an adjusting member 210, a gear member 220, and a pulley member 230. Pushing the adjusting member 210 can drive the gear member 220 to move, and the movement of the gear member 220 can drive the pulley member 230 to move, so that the closing mechanism 100 is in a non-closed position.

[0047] Specifically, the adjusting member 210 can be configured as a cylindrical rod structure. Pushing the adjusting member 210 can drive the gear member 220 to move in the opposite direction. The reverse movement of the gear member 220 can drive the pulley member 230 to move in the opposite direction, thereby making the closing mechanism 100 in a non-closed state.

[0048] See appendix Figure 2 and attached Figure 3 As shown, in some embodiments, the adjusting member 210 also includes a toothed ring 211, and the gap between adjacent toothed rings 211 can cooperate with the teeth of the gear member 220. Pushing the toothed ring 211 of the adjusting member 210 can drive the gear member 220 to move, so that the closing mechanism 100 is in a non-closed position.

[0049] Specifically, the adjusting member 210 includes a toothed ring 211. More toothed rings 211 are provided and distributed at intervals. The toothed rings 211 are distributed in a ring shape on the adjusting member 210. The teeth of the toothed rings 211 and the gear members 220 can cooperate with each other. Specifically, the size of each tooth on the gear members 220 is adapted to the gap between two adjacent toothed rings 211. When the adjusting member 210 is pushed, the teeth on the gear members 220 can engage with the gap between the toothed rings 211, causing the gear members 220 to rotate counterclockwise, so that the closing mechanism 100 is in a non-closed position.

[0050] Specifically, the control mechanism 200 has a sliding channel, and one end of the adjusting member 210 with a toothed ring is disposed in the sliding channel, while the other end of the adjusting member 210 extends out of the sliding channel. The sliding channel includes a sliding hole, and the diameter of the sliding channel is larger than the diameter of the toothed ring on the adjusting member 210. The toothed ring can slide freely in the control mechanism and will not rub against the inner wall of the control mechanism 200. The diameter of the sliding hole is smaller than the diameter of the toothed ring, so the adjusting member 210 can slide in the sliding channel and will not fall out of the control mechanism.

[0051] See appendix Figure 2 To be continued Figure 4 As shown, in some embodiments, one end of the adjusting member 210 extends out of the control mechanism 200, and the other end of the adjusting member 210 is provided with a thread. The locking member includes a threaded hole 240, which is disposed opposite to the threaded end of the adjusting member 210. When the adjusting member 210 is pushed to engage with the threaded hole 240, rotating the adjusting member 210 can lock the adjusting member 210 and the threaded hole 240, so that the closing mechanism 100 is kept in the non-closed position.

[0052] Specifically, one end of the adjusting member 210 extends out of the control mechanism 200, allowing the user to push or press the adjusting member 210. The other end of the adjusting member 210 is threaded, allowing the user to choose to push and hold the adjusting member 210 in its depressed state during urination, or to push the adjusting member 210 until it is fully depressed. A threaded hole 240 is provided at the threaded end of the adjusting member 210, which can engage with the thread on the adjusting member 210. Simply rotating the adjusting member 210 to turn the thread into the threaded hole 240 locks the adjusting member 210, keeping the closing mechanism 100 in an open state. The user does not need to continuously press the adjusting member 210 during urination. The adjusting member 210 remains locked through the threaded hole 240 until the user rotates the adjusting member 210 to release it from the threaded hole 240. When the adjusting member 210 is released, it returns to its initial state.

[0053] See appendix Figure 5 As shown, in some embodiments, the pulley 230 is provided with an offset member 231 at its center. When the rotating adjustment member 210 disengages from the threaded hole 240, the offset member 231 enables the closing mechanism 100 to return to the closed position.

[0054] Specifically, the biasing member 231 can be configured as a spring, located at the center of the pulley member 230. The spring is biased to apply an initial tension force to the closure mechanism 100. When the closure device is inserted, the tension force is transmitted to the flexible portion 110 of the closure mechanism 100, causing the closure mechanism 100 to be in the closed position in the initial state. When the user rotates the adjusting member 210 to disengage from the threaded hole 240 after urinating, the adjusting member 210 can return to its initial state under the influence of the spring, causing the closure mechanism 100 to return to the closed position.

[0055] See appendix Figure 7As shown, in some embodiments, the closure mechanism 100 includes at least one suture cavity 130 extending from the flexible portion 110 to the tube portion 120. The suture cavity 130 is provided with a traction suture 131, which is connected to the control mechanism 200. The traction suture 131 can be driven by the control mechanism 200 to a closed position and an unclosed position.

[0056] Specifically, the traction suture 131 extends from the flexible portion 110 to the conduit portion 120. The traction suture 131 connects to the pulley member 230 of the control mechanism 200. When the closure mechanism 100 is in the closed position, the traction suture 131 is tensioned by the biasing member 231, meaning the traction suture 131 provides closing pressure to the closure mechanism 100. When the closure mechanism 100 is in the open position, i.e., when unobstructed urination is required, the closing pressure needs to be removed. This is achieved by the reverse rotation of the pulley member 230, which removes the tension on the traction suture 131. The function of the traction suture 131 is to allow the tension applied by the control mechanism 200 to be transmitted through the traction suture 131 to the flexible portion 110 of the closure mechanism 100, facilitating the bending of the portion to both the closed and open positions.

[0057] See appendix Figure 6 As shown, in some embodiments, a connector 111 is provided at the first end of the flexible portion 110 away from the pipe portion 120, and a connection position 112 is provided at the second end of the flexible portion 110. The connector 111 can be connected to the connection position 112, so that the flexible portion 110 can surround the conduit 300.

[0058] Optionally, the connector 111 can be configured as a plug-in, and the connection position 112 can be configured as a connection hole. The plug-in can be inserted into the connection hole. In this structure, it is only necessary for the connector 111 to be able to connect with the connection position 112 so that the bendable part 110 remains in an annular state and wraps around the conduit 300.

[0059] Specifically, the connection position 112 can be set at any position at the second end of the closing mechanism 100, as long as there is a sufficiently long flexible portion 110 so as to accommodate conduits 300 of different sizes and diameters.

[0060] See appendix Figure 1 As shown, in some embodiments, the connector 111 is also provided with a positioning member 1111. The positioning member 1111 is detachably connected to the connector 111. The positioning member 1111 is used to help position the flexible part 110 against the outer surface of the conduit 300, so that the flexible part 110 can surround the conduit 300.

[0061] Specifically, the positioning element 1111 can be a symmetrically arranged protruding rod-shaped structure on both sides of the connector 111 to help position the closure mechanism 100 surrounding the catheter 300 through the surgically formed channel. The positioning element 1111 guides the insert into the connection hole. The positioning element 1111 helps position the closure mechanism 100 against the adjacent catheter 300, surrounding the outer surface of the catheter 300 so that the connector 111 can be connected to the connection position 112. The positioning element 1111 and the connector 111 are detachably connected. After the connector 111 is locked to the connection position 112, the positioning element 1111 can be removed.

[0062] See appendix Figure 8 As shown, in some embodiments, the closing mechanism 100 further includes a receiving cavity 140 extending from the flexible portion 110 to the pipe portion 120. The receiving cavity 140 within the pipe portion 120 is provided with a rigid member 141, which is used to increase the rigidity of the pipe portion 120.

[0063] Specifically, the rigid member 141 may be provided with a tightly wound coil of wire that passes through the receiving cavity 140 of the pipe section 120, thereby increasing the rigidity of the pipe section 120 to prevent it from being flattened.

[0064] See appendix Figure 1 As shown, in some embodiments, the control mechanism 200 is covered with a thin film 250, which can guide the solution into the control mechanism 200 and the closing mechanism 100.

[0065] Specifically, the thin film 250 on the control mechanism 200 can be inserted by a syringe, which can penetrate the user's skin and enter the thin film 250 to easily inject into the control mechanism 200. It can also easily enter the flexible portion 110 of the closing mechanism 100 through capillary action. Specifically, the closing mechanism 100 has a porous structure that allows the solution to flow out from the surface of the closing mechanism 100. Therefore, the solution can flow out from the porous structure of the closing mechanism 100 to the surrounding tissue, thereby exerting the drug effect.

[0066] Specifically, the solution can be designed to prevent postoperative infection or other therapeutic effects; for example, the solution can be an antibiotic, an anti-inflammatory drug, or an anti-proliferative drug.

[0067] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
