Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a snap-fit ​​structure of an artificial contractile structure. Background Art

[0002] With the development of medical technology, artificial contractile structures have been widely used. Artificial contractile structures are suitable for assisting atrial or ventricular contraction, or assisting or replacing natural sphincters. In recent years, artificial sphincters are often used for urethral control and assisted urethral treatment. Artificial sphincters usually require a reliable and easy-to-operate snap-fit ​​structure to adjust their tightness to meet the needs of different users or the needs of the same user at different times. Traditional snap-fit ​​structures may have problems such as inconvenient operation, complex structure, high cost or insufficient reliability. Therefore, it is very necessary to provide a reliable snap-fit ​​structure for an artificial contractile structure.

[0003] However, one of the shortcomings of the related art is that the conventional snap-fitting structure of the artificial contractile structure usually uses a plug-in snap-fitting structure, which has a low bearing capacity and results in a poor snap-fitting effect. Utility Model Content

[0004] The utility model aims to solve at least one of the above technical problems.

[0005] In order to solve the above problems, the first object of the present invention is to provide a snap-fit ​​structure of an artificial contractile structure.

[0006] To achieve the first purpose of the present invention, an embodiment of the utility model provides a snap-fit ​​structure of an artificial contractile structure, the artificial contractile structure includes a controller and a restraint belt, the snap-fit ​​structure of the artificial contractile structure includes: a pressing block, the pressing block is arranged at one end of the restraint belt close to the controller; a locking block, the locking block is arranged at one end of the controller close to the restraint belt, the locking block and the pressing block abut against each other; wherein, the pressing block is provided with a fixing boss, the locking member is provided with a locking boss, and the fixing boss and the locking boss abut against each other.

[0007] As a part, the controller can be used to control and adjust the contraction process of the artificial contractile structure to adapt it to different needs and application scenarios. Through the mutual abutment between the pressing block and the locking block, and the mutual abutment between the fixing boss and the locking boss, the snap-fit ​​structure can provide stable fastening performance and ensure a firm connection of the structure. Due to the design of the snap-fit ​​structure, it can provide higher reliability and durability, ensuring the stability and durability of the structure in long-term use. And the setting of the fixing boss and the locking boss can play a certain positioning role, making it more accurately positioned during assembly, thereby improving the reliability of the artificial contractile structure.

[0008] In the above technical solution, the pressing block is provided with a locking groove, and the locking boss and the locking groove cooperate with each other.

[0009] The beneficial effect of providing a locking groove on the pressing block and the cooperation between the locking boss and the locking groove is to increase the stability and reliability of the snap-fit ​​structure. The cooperation between the locking boss and the locking groove can ensure that the snap-fit ​​structure can maintain a good locking state under the condition of external force or vibration, and is not easy to loosen or fail. This design can provide better safety and reliability, ensuring the normal operation and use of the artificial contractile structure. In addition, the setting of the locking groove can accurately find the installation position of the locking boss during the assembly process, thereby improving the convenience and accuracy of the equipment installation.

[0010] In any of the above technical solutions, the locking block is provided with a fixing groove, and the fixing boss cooperates with the fixing groove.

[0011] Through the cooperation of the fixing boss and the fixing groove, a reliable connection between the locking block and the pressing block can be achieved. This connection mechanism can prevent the artificial contractile structure from accidentally being untied or loosened during use, thereby ensuring the reliability and stability of the structure. The presence of the fixing groove enables the locking block to be firmly fixed in the corresponding position when engaged, and the design of the fixing boss matches it, further enhancing the tightness of the engagement. In addition, the setting of the fixing groove enables the installation position of the fixing boss to be accurately found during the assembly process, thereby improving the convenience and accuracy of equipment installation.

[0012] In any of the above technical solutions, the pressing block is provided with a positioning block, and the positioning block extends toward the inside of the restraint belt.

[0013] There is a pull rod on the inner side of the restraint. When assembling the controller and the controller, a certain force is required, which may cause the pull rod to be subjected to a certain force, thereby shrinking the restraint, causing the determined restraint size to change, and affecting the effect of the artificial contractile structure. The setting of the clamping block can clamp the pull rod when assembling the controller and the controller, avoiding unnecessary movement of the pull rod, which causes the size of the restraint to change.

[0014] In any of the above technical solutions, the restraint belt is provided with a sealing ring, and the sealing ring is located at one end of the restraint belt close to the controller.

[0015] The presence of the sealing ring can provide sealing performance. When the artificial contractile structure is in the engaged state, the sealing ring located at one end of the restraint band can effectively prevent impurities, liquids or gases in the external environment from entering the interior of the structure. This can avoid contamination, corrosion or damage to internal components while protecting the normal operation of the structure. In addition, the sealing ring can provide a waterproof function. By setting the sealing ring, the possibility of moisture entering the artificial contractile structure can be reduced. This is particularly important for structures used in humid or underwater environments, which can maintain the stability and reliability of the structure and extend its service life. The sealing ring can also provide a dustproof function. It can prevent dust, particles or other fine matter from entering the interior of the structure, thereby reducing the risk of wear and blockage of the internal mechanism. This helps to maintain the performance and operating efficiency of the structure. Therefore, the setting of the sealing ring can achieve effective sealing, waterproof and dustproof functions, protect the internal components of the artificial contractile structure, and improve the reliability and durability of the structure.

[0016] In any of the above technical solutions, the controller is provided with a sealing groove, which is located at one end of the controller close to the restraining belt, and the sealing ring cooperates with the sealing groove.

[0017] By matching the sealing groove with the sealing ring, external substances such as liquid or gas can be effectively prevented from entering or leaking out of the artificial contractile structure. The matching of the sealing groove and the sealing ring forms a sealing interface, which can provide a good sealing effect. In addition, the design of the sealing groove and the sealing ring can also provide better durability and stability. They can reduce friction and wear inside the structure and extend the service life of the artificial contractile structure. Therefore, the design of the sealing groove and the sealing ring enhances the sealing performance of the artificial contractile structure, ensures the stability and reliability of the internal environment, and improves the performance and life of the equipment or device.

[0018] In any of the above technical solutions, the restraint belt is provided with a limit block, and the limit block is located at one end of the restraint belt close to the controller.

[0019] The presence of the limit block can help achieve precise positioning and ensure the accuracy and stability of the artificial contractile structure during use. The limit block can be used as a reference point to help determine the position of the restraint and the position relative to the controller, thereby controlling the expansion and contraction state of the structure. The setting of the limit block can limit the expansion and contraction range of the artificial contractile structure to avoid over-extension or over-contraction. When the structure reaches the limit block, it will provide a stop point to prevent further expansion and contraction, thereby protecting the integrity and reliability of the structure. The presence of the limit block can protect the controller and the restraint. When the structure reaches the limit block, it can reduce the impact of external forces on the controller and the restraint to avoid damage or excessive stress. The setting of the limit block can constrain the deformation range of the artificial contractile structure to ensure that it remains stable and controllable within a specific working range. By limiting the deformation of the structure, the performance and function of the structure can be optimized, and its working efficiency and reliability can be improved.

[0020] In any of the above technical solutions, the controller is provided with a limit groove, which is located at one end of the controller close to the restraining belt, and the limit block cooperates with the limit groove.

[0021] The cooperation of the limit slot and the limit block can limit the range of movement of the artificial contractile structure in the engaged state. The existence of the limit slot can ensure that the structure stops at a specific position, thereby achieving position control and fixation. This is very important for applications that require precise control and reliable stability. The cooperation of the limit slot and the limit block can also prevent the artificial contractile structure from over-extension or contraction. By limiting the range of motion of the retractable part, the limit slot and the limit block can prevent the structure from being subjected to unnecessary stress or damage and ensure that it operates within a safe working range. The design of the limit slot and the limit block helps to improve the reliability and durability of the entire artificial contractile structure. By limiting the range of motion of the structure and preventing it from exceeding the design parameters, it can reduce wear and damage to parts and extend the service life of the structure.

[0022] In any of the above technical solutions, the restraint belt is provided with a traction block, and the traction block is located at one end of the restraint belt close to the controller.

[0023] The presence of the traction block makes it easier to control and manipulate the restraint. By pulling or pushing the traction block, the operator can adjust and control the contractility of the restraint, thereby achieving precise adjustment of the artificial contractile structure. The use of the traction block can improve the stability and safety of the structure. The traction block can tightly fix the restraint to the controller to prevent the structure from loosening or accidentally untying, thereby ensuring the stability and reliability of the structure during use.

[0024] In any of the above technical solutions, the controller is provided with a telescopic block, which is located at one end of the controller close to the restraining belt, and the telescopic block cooperates with the traction block.

[0025] The presence of the telescopic block enables the controller to control the length of the restraint belt. By adjusting the position of the telescopic block to drive the traction block, the degree of contraction of the restraint belt can be changed. This adjustment can accurately control the length of the artificial contractile structure according to specific needs. The cooperation of the telescopic block and the traction block can provide an adjustable tightening force. By changing the relative position of the telescopic block and the traction block, the degree of tightening of the snap-fit ​​structure can be increased or decreased, thereby controlling the tightening force of the restraint belt. This adjustment can adapt to different application requirements and ensure that the structure is stable and reliable during use. The cooperation of the telescopic block and the traction block provides a more secure snap-fit ​​mechanism. Their interaction can enhance the ability of the snap-fit ​​structure to resist external forces and reduce the risk of loosening or accidental release of the structure. This helps to ensure that the artificial contractile structure remains stable during use and reduce the occurrence of unexpected failures. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Refer to the following Figures 1 to 3 The technical solutions of some embodiments of the utility model are described.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the utility model provides a snap-fit ​​structure of an artificial contractile structure, the artificial contractile structure includes a controller 100 and a restraining belt 200, and is characterized in that the snap-fit ​​structure includes: a pressing block 210, the pressing block 210 is arranged at one end of the restraining belt 200 close to the controller 100; a locking block 110, the locking block 110 is arranged at one end of the controller 100 close to the restraining belt 200, and the locking block 110 and the pressing block 210 abut against each other; wherein, the pressing block 210 is provided with a fixing boss 211, the locking block 110 is provided with a locking boss 111, and the fixing boss 211 and the locking boss 111 abut against each other.

[0035] In this embodiment, the artificial contractile structure is provided with two engaging structures, and the structures of the two engaging structures are exactly the same, and they play a role of limiting and fixing from the upper and lower sides respectively, so that the engaging effect is better. The pressing block 210 is located on the outer shell of the restraint belt 200, and the pressing block 210 can slide up and down. The fixing boss 211 and the locking boss 111 are partially in contact with each other, so as to achieve the effect of limiting the left and right movement of the restraint belt 200. Since the position of the locking boss 111 is fixed, the fixing boss 211 can be moved away from the locking boss 111 by pressing the pressing block 210, and the restraint belt 200 can be pulled out of the controller 100 at this time.

[0036] like Figure 2 As shown, the pressing block 210 is provided with a locking groove 212 , and the locking boss 111 cooperates with the locking groove 212 ; the locking block 110 is provided with a fixing groove 112 , and the fixing boss 211 cooperates with the fixing groove 112 .

[0037] In this embodiment, the locking boss 111 extends into the locking groove 212, and the fixing boss 211 extends into the fixing groove 112, so as to limit the left and right movement of the locking boss 111 and the fixing boss 211, thereby achieving a good engagement effect.

[0038] like Figure 1 As shown, the pressing block 210 is provided with a locking block 220 , and the locking block 220 extends toward the inside of the restraining belt 200 .

[0039] In this embodiment, a pull rod is provided inside the restraint belt 200, and some grooves are provided on both sides of the pull rod. When the pressing block 210 is pressed down for assembly or disassembly, the locking block 220 moves downward and extends into the groove to clamp the pull rod, thereby preventing the pull rod from being moved during the assembly or disassembly process, causing the tightness of the restraint belt 200 to change, affecting the use effect of the artificial contractile structure.

[0040] like Figure 2 As shown, the restraint belt 200 is provided with a sealing ring 230, which is located at one end of the restraint belt 200 close to the controller 100; the controller 100 is provided with a sealing groove 130, which is located at one end of the controller 100 close to the restraint belt 200, and the sealing ring 230 cooperates with the sealing groove 130.

The limit block 240 can use a water-swelling material. When the sealing ring 230 and the sealing groove 130 do not completely block the tissue fluid, the limit block 240 will swell with water and completely fill the limit groove 140 to form a second sealing layer, thereby further isolating the tissue fluid in the human body.

[0044] like Figure 2 As shown, the restraint belt 200 is provided with a traction block 250, which is located at one end of the restraint belt 200 close to the controller 100; the controller 100 is provided with a telescopic block 150, which is located at one end of the controller 100 close to the restraint belt 200, and the telescopic block 150 cooperates with the traction block 250.

[0045] In this embodiment, a pull rod is provided inside the restraint belt 200, and a traction block 250 is provided at the head of the pull rod. The traction block 250 protrudes outward and is inserted into the groove in the telescopic block 150. When the telescopic block 150 is extended or retracted, the traction block 250 is driven to move, thereby driving the pull rod to move, thereby achieving the effect of changing the tightness of the restraint belt 200.
