[0056] The following will describe the multi - level button assembly for a steam ablation device of this application in conjunction with Figures 1 to 12 Describe the multi - level button assembly for the steam ablation device of this application.

[0057] A multi - level button assembly for a steam ablation device according to an embodiment of this application, please refer to Figures 1 to 6 , the multi - level button assembly includes a device main body 10, an external button 200, and an internal button 100. The external button 200 is provided on the device main body 10, and the external button 200 has a hollow structure inside; the internal button 100 is inserted through the hollow structure, and the internal button 100 is adapted to move independently relative to the external button 200; the device main body 10 includes a first button 11 and a second button 12, and the internal button 100 is adapted to press and trigger the first button 11, and the external button 200 is adapted to press and trigger the second button 12.

[0058] For the multi - level button assembly for a steam ablation device according to an embodiment of this application, since the internal button 100 can move independently relative to the external button 200, the user can selectively trigger the internal button 100, or press the internal button 100 and the external button 200 simultaneously to perform different operations or achieve different operation effects.

[0059] It should be noted that a steam ablation device is a medical device that can use high - temperature steam to perform ablation treatment on target tissues. The multi - level button assembly for a steam ablation device of this application (hereinafter simply referred to as the multi - level button assembly) is a control assembly composed of multiple buttons (such as the external button 200 and the internal button 100 in this example), and realizes various operation functions of the steam ablation device through different pressing methods.

[0060] The hollow structure refers to the hollow cavity inside the external button 200, which is used to accommodate the internal button 100 and allow its relative independent movement, where the independent movement means that the internal button 100 can be pressed independently.

[0061] It can be understood that by integrating the functions of two buttons into a multi-level button component, the number of buttons on the device surface can be reduced, making the device appearance more concise. And since the internal button 100 and the external button 200 can trigger different functions independently, users can achieve multiple operation modes by pressing the internal and external buttons 200 separately or in combination, greatly improving the flexibility and convenience of operation.

[0062] In one embodiment, the multi-level button component can trigger three different functions by pressing the button in different ways. Specifically, refer to the following table:

[0063]

[0064] It should be noted that Function 1, Function 2, and Function 3 can respectively execute different functions corresponding to the steam ablation device, thus effectively realizing the hierarchical control of the multiple functions of the steam ablation device.

[0065] According to an embodiment of the present application, please refer to Figures 1 to 5 , the multi-level button component includes a linkage button 300 and a first elastic member 400. The linkage button 300 is connected to the side of the internal button 100 facing the first button 11; the first end of the first elastic member 400 is connected to the linkage button 300, and the second end of the first elastic member 400 is connected to the internal button 100.

[0066] The linkage button 300 is used to transfer the pressing action of the internal button 100 to the first button 11. The first elastic member 400 is an elastic element, such as a spring or an elastic sheet, etc., which is used to provide elastic support between the internal button 100 and the linkage button 300 to ensure that the internal button 100 can return to its original position after being pressed. The first end and the second end of the first elastic member 400 are respectively connected to the linkage button 300 and the internal button 100 to form an elastic connection. By introducing the linkage button 300 and the first elastic member 400, users can feel a more obvious feedback force when pressing the internal button 100, which helps to improve the accuracy and feel of operation.

[0067] According to an embodiment of the present application, please refer to Figures 1 to 5 , the multi-level button component includes a balance support button 500 and a second elastic member 600. The balance support button 500 is connected to the side of the internal button 100 facing the device main body 10. The balance support button 500 is provided in the middle of the internal button 100, and the linkage button 300 is provided beside the balance support button 500; the second elastic member 600 is sleeved on the balance support button 500. The first end of the second elastic member 600 faces the device main body 10, and the second end of the second elastic member 600 faces the internal button 100.

[0068] The balancing support button 500 is located in the middle of the internal button 100, and provides additional support force when the internal button 100 is pressed, thereby enhancing the stability of the internal button 100 during the pressing process and reducing inaccurate pressing caused by deviation or shaking.

[0069] The second elastic member 600 is an elastic element sleeved on the balance support button 500, and is used to provide elastic support between the internal button 100 and the balance support button 500. The first end and the second end of the second elastic member 600 are respectively facing the device body 10 and the internal button 100, forming an elastic connection. This design helps the internal button 100 to automatically return to its original position after being pressed.

[0070] It can be understood that the combined design of the balance support button 500 and the second elastic member 600 enables the user to feel a more balanced and comfortable pressing force when pressing the internal button 100, thereby improving the overall operating experience.

[0071] According to an embodiment of the present application, please refer to Figures 1 to 5 A first mounting groove 310 is provided on the side of the linkage button 300 facing the internal button 100, and a first end of the first elastic member 400 is provided in the first mounting groove 310; a second mounting groove 110 is provided on the side of the internal button 100 facing the linkage button 300, and a second end of the first elastic member 400 is provided in the second mounting groove 110.

[0072] The first mounting groove 310 is used to accommodate the first end of the first elastic member 400. The shape and size of the mounting groove match the first end of the first elastic member 400 to ensure that the elastic member can be stably mounted therein.

[0073] A groove or hole is designed on the inner button 100 to accommodate the second end of the first elastic member 400. The shape and size of the second mounting groove 110 match the second end of the first elastic member 400 to achieve a stable connection. Through the first mounting groove 310 and the second mounting groove 110, the first elastic member 400 can form a stable elastic connection between the linkage button 300 and the inner button 100.

[0074] It is understandable that the two ends of the first elastic member 400 are respectively embedded in the first mounting groove 310 and the second mounting groove 110, forming a stable connection structure. This connection method helps to reduce the loosening or falling off of the elastic member due to vibration or external force, thereby improving the reliability and durability of the multi-stage button assembly.

[0075] According to an embodiment of the present application, please refer to Figures 1 to 5, a third elastic member 700 is provided between the balance support button 500 and the internal button 100. A third installation groove 510 is provided on the side of the balance support button 500 facing the internal button 100. The first end of the third elastic member 700 is arranged in the third installation groove 510. A fourth installation groove 120 is provided on the side of the internal button 100 facing the balance support button 500. The second end of the third elastic member 700 is arranged in the fourth installation groove 120.

[0076] The third elastic member 700 is located between the balance support button 500 and the internal button 100, and is used to provide additional elastic support and buffering effect. Its first end and second end are respectively embedded in the third installation groove 510 and the fourth installation groove 120 to form a stable connection structure.

[0077] It can be understood that adding the third elastic member 700 between the balance support button 500 and the internal button 100 can further increase the buffering effect and recovery effect of the multi-stage button assembly. When the internal button 100 is pressed, the third elastic member 700 can provide a restoring force to return to the original position. By adding the third elastic member 700, users can feel a smoother and more uniform pressing force when pressing the internal button 100, thus improving the overall operation comfort and user experience.

[0078] According to an embodiment of the present application, please refer to Figures 1 to 5 , the device body 10 is provided with a fifth installation groove 13 corresponding to the balance support button 500. The shape, size and position of the fifth installation groove 13 match those of the balance support button 500 to ensure that the balance support button 500 can be firmly abutted against the fifth installation groove 13.

[0079] It can be understood that by providing the fifth installation groove 13 corresponding to the balance support button 500 on the device body 10, a stable support point for the balance support button 500 inside the device can be ensured. This helps to reduce the shaking or offset generated by the internal button 100 during pressing, thereby enhancing the structural stability of the entire multi-stage button assembly.

[0080] According to an embodiment of the present application, please refer to Figures 6 to 12 , the multi-stage button assembly includes a fixed limiting member 800. The fixed limiting member 800 is connected to the external button 200. The fixed limiting member 800 is provided with a first installation hole 810 and a second installation hole 820. The linkage button 300 is arranged in the first installation hole 810, and the balance support button 500 is arranged in the second installation hole 820.

[0081] It can be understood that the fixed limiting member 800 is used to fix and limit the linkage button 300 and the balance support button 500. The first mounting hole 810 is used to accommodate the linkage button 300, and the shape, size and position of the first mounting hole 810 match those of the linkage button 300 to ensure that it can be stably mounted on the fixed limiting member 800. The second mounting hole 820 is used to accommodate the balance support button 500, and the shape, size and position of the second mounting hole 820 match those of the balance support button 500 to ensure that it can be stably mounted on the fixed limiting member 800.

[0082] It can be understood that the linkage button 300 and the balance support button 500 are tightly connected to the external button 200 through the fixed limiting member 800, forming a stable overall structure. The design of the first mounting hole 810 and the second mounting hole 820 ensures the accurate positions of the linkage button 300 and the balance support button 500 on the fixed limiting member 800, improving the reliability and durability of the multi-stage button assembly.

[0083] According to an embodiment of the present application, please refer to Figures 1 to 5 , Figure 10 and Figure 11 , the internal button 100 is provided with a first sliding limiting structure 130, the external button 200 is provided with a second sliding limiting structure 210, the second sliding limiting structure 210 is arranged corresponding to the first sliding limiting structure 130, and the first sliding limiting structure 130 is slidably connected to the second sliding limiting structure 210.

[0084] The first sliding limiting structure 130 is used to cooperate with the second sliding limiting structure 210 on the external button 200 to achieve a smooth sliding connection between the two. The second sliding limiting structure 210 corresponds to the first sliding limiting structure 130 on the internal button 100 and has a shape, size and position matching those of the first sliding limiting structure 130 to achieve a tight fit and smooth sliding between the two.

[0085] It can be understood that through the first sliding limiting structure 130 and the second sliding limiting structure 210 respectively provided on the internal button 100 and the external button 200, a smooth sliding connection between the two is achieved. It not only ensures the relative position relationship between the internal button 100 and the external button 200, but also limits the relative movement range between them. This structural stability helps to prevent the internal button 100 from shifting or shaking during pressing, thereby improving the overall reliability of the multi-stage button assembly.

[0086] According to an embodiment of the present application, the first sliding limiting structure 130 includes at least one of a sliding groove and a limiting rib, and the second sliding limiting structure 210 is arranged corresponding to the first sliding limiting structure 130.

[0087] The sliding groove can be a recess or a channel for guiding a corresponding part (such as a limiting rib) on the external button 200 to slide. The limiting rib can be a protrusion or a rib for cooperating with the sliding groove on the internal button 100. The limiting rib can play a role in guiding and limiting during the sliding process to prevent the internal button 100 from deviating from the predetermined trajectory or shaking during sliding. Through the close cooperation between the limiting rib and the sliding groove, a stable connection and smooth sliding between the internal button 100 and the external button 200 can be achieved.

[0088] It should be noted that the third sliding limiting structure 220, the fifth limiting structure, and the seventh limiting structure mentioned later can also include at least one of the sliding groove and the limiting rib, which will not be elaborated here.

[0089] According to an embodiment of the present application, the number of the first sliding limiting structures 130 is multiple, and at least one first sliding limiting structure 130 is located on different sides of the internal button 100, and the second sliding limiting structure 210 is arranged corresponding to the first sliding limiting structure 130.

[0090] It can be understood that by arranging multiple first sliding limiting structures 130 on different sides of the internal button 100, the multi-directional stability of the internal button 100 inside the external button 200 can be ensured. This multi-directional limiting design reduces the offset or shaking generated during the pressing or sliding process of the internal button 100 and improves the overall stability of the multi-stage button assembly.

[0091] According to an embodiment of the present application, please refer to Figures 1 to 5 and Figure 11 , the external button 200 is provided with a third sliding limiting structure 220, and the device main body 10 is provided with a fourth sliding limiting structure 14. The fourth sliding limiting structure 14 is arranged corresponding to the third sliding limiting structure 220, and the third sliding limiting structure 220 is slidably connected to the fourth sliding limiting structure 14.

[0092] It can be understood that the third sliding limiting structure 220 is used to cooperate with the fourth sliding limiting structure 14 on the device main body 10 to achieve a smooth sliding connection between the two. The fourth sliding limiting structure 14 corresponds to the third sliding limiting structure 220 on the external button 200. It usually has a shape, size, and position matching the third sliding limiting structure 220 to achieve a tight fit and smooth sliding between the two.

[0093] It can be understood that adding the third sliding limiting structure 220 and the fourth sliding limiting structure 14 between the external button 200 and the device main body 10 enhances the connection stability between the internal button 100 and the external button 200, enabling the user to feel a more stable and smooth operation experience when pressing or sliding the external button 200.

[0094] According to an embodiment of the present application, the linkage button 300 is provided with a fifth sliding limit structure 320, and the internal button 100 is provided with a sixth sliding limit structure 140. The sixth sliding limit structure 140 is arranged corresponding to the fifth sliding limit structure 320, and the fifth sliding limit structure 320 is slidably connected to the sixth sliding limit structure 140.

[0095] The fifth sliding limit structure 320 is used to cooperate with the sixth sliding limit structure 140 on the internal button 100 to achieve a smooth sliding connection between the two. The sixth sliding limit structure 140 corresponds to the fifth sliding limit structure 320 on the linkage button 300 and has a shape, size and position matching those of the fifth sliding limit structure 320 to achieve a tight fit and smooth sliding between the two.

[0096] It can be understood that through the fifth sliding limit structure 320 and the sixth sliding limit structure 140 respectively provided on the linkage button 300 and the internal button 100, a smooth sliding connection between the two is achieved. This not only ensures the relative position relationship between the internal button 100 and the linkage button 300, but also limits the relative movement range between them. This structural stability helps to prevent the internal button 100 from shifting or shaking during pressing, thereby improving the overall reliability of the multi-stage button assembly.

[0097] According to an embodiment of the present application, the balance support button 500 is provided with a seventh sliding limit structure 520, and the internal button 100 is provided with an eighth sliding limit structure 150. The eighth sliding limit structure 150 is arranged corresponding to the seventh sliding limit structure 520, and the seventh sliding limit structure 520 is slidably connected to the eighth sliding limit structure 150.

[0098] The seventh sliding limit structure 520 is used to cooperate with the eighth sliding limit structure 150 on the internal button 100 to achieve a smooth sliding connection between the two. The eighth sliding limit structure 150 corresponds to the seventh sliding limit structure 520 on the balance support button 500 and has a shape, size and position matching those of the seventh sliding limit structure 520 to achieve a tight fit and smooth sliding between the two.

[0099] It can be understood that through the seventh sliding limit structure 520 and the eighth sliding limit structure 150 respectively provided on the balance support button 500 and the internal button 100, a smooth sliding connection between the two is achieved. This not only ensures the relative position relationship between the internal button 100 and the balance support button 500, but also limits the relative movement range between them. This structural stability helps to prevent the internal button 100 from shifting or shaking during pressing, thereby improving the overall reliability of the multi-stage button assembly.

[0100] In one embodiment, a concave groove is provided in the middle of the internal button 100, and this concave groove can generate a certain deformation.

[0101] In one embodiment, please refer to Figures 6 to 9 , press the internal button 100, and the first elastic member 400 pushes the linkage button 300 into contact with the first button 11 of the device body 10 until the function 1 of the steam ablation device corresponding to the first button 11 is triggered.
