DETAILED DESCRIPTION

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0026] In order to solve the problem of poor waterproof performance of the foot switch in the prior art, this embodiment provides a single-stage foot switch. Figure 4 As shown, the single-stage foot switch of this embodiment includes a base 1, an upper cover 7, and a pedal. The pedal is hingedly arranged on the base 1, an electronic switch 6 is arranged inside the base 1, a push rod fixing rod 3 is arranged on the base 1, a push rod 5 is arranged inside the push rod fixing rod 3, and a waterproof device is arranged between the push rod fixing rod 3 and the push rod 5; when in use, an external force is applied to the pedal, thereby driving the push rod 5 to slide relative to the push rod fixing rod 3, and then triggering the electronic switch to realize the function of the foot switch, that is, controlling the device.

[0027] Example 1

[0028] like Figure 1 As shown, the single-stage foot switch provided in this embodiment includes a base 1, a push rod 5, a push rod fixing rod 3, an electronic switch 6, and a reset member 2. The base 1 is tightly connected to the push rod fixing rod 3, the push rod 5 is slidably arranged inside the push rod fixing rod 3, the push rod 5 is used to trigger the electronic switch 6, and the reset member 2 is used to reset the push rod 5. A silicone sleeve 4 is arranged between the push rod fixing rod 3 and the push rod 5, a first fixing groove 3-1 is arranged on the push rod fixing rod 3, and a second fixing groove 5-1 is arranged on the push rod 5, one end of the silicone sleeve 4 cooperates with the first fixing groove 3-1, and the other end of the silicone sleeve 4 cooperates with the second fixing groove 5-1.

[0029] During use, an external force is applied to the pedal, thereby driving the push rod 5 to slide relative to the push rod fixing rod 3. When the push rod 5 slides relative to the push rod fixing rod 3, the silicone sleeve 4 is deformed along the direction of movement of the push rod 5. When the external force applied to the pedal is removed, the reset member 2 returns to its initial position under the action of its own elastic potential energy, thereby driving the push rod 5 to move relative to the push rod fixing rod 3 and return to its initial position.

[0030] Therefore, the single-stage foot switch of this embodiment has excellent waterproof performance. During use, even if contaminants enter the interior of the device, it will not cause damage to the device and thus have a negative impact on the operation.

[0031] In addition, this embodiment also provides a high-frequency surgical device, including a main body and the single-stage foot switch provided in this embodiment.

[0032] Example 2

[0033] like Figure 2 As shown, in this embodiment, the silicone sleeve 4 can be a cylindrical structure, the rear section of the silicone sleeve 4 can be provided with a fixing protrusion 4-2, the front section of the silicone sleeve 4 can be provided with an inner flange 4-1, the fixing protrusion 4-2 can cooperate with the first fixing groove 3-1, and the inner flange 4-1 can cooperate with the second fixing groove 5-1.

[0034] As a further optimization of this embodiment, the first fixing groove 3-1 can be opened along the axial direction of the push rod fixing rod 3, and can be located on the front end surface of the push rod fixing rod 3, and the fixing protrusion 4-2 can be inserted into the first fixing groove 3-1; the second fixing groove 5-1 can be opened along the radial direction of the push rod 5, and can be located on the front end surface of the push rod 5, and the inner flange 4-1 can be inserted into the second fixing groove 5-1.

[0035] As a further optimization of this embodiment, the silicone sleeve 4 may include at least two fixing protrusions 4-2, and among the at least two fixing protrusions 4-2, the outer diameter of the fixing protrusion 4-2 located on the outside may be larger than the outer diameter of the fixing protrusion 4-2 located on the inside.

[0036] Example 3

[0037] like Figures 3 to 8 As shown, in this embodiment, the reset member 2 can be a compression spring, a torsion spring, a damper, or any other component that can achieve similar functions, and the rear section of the push rod 5 can be provided with a protruding structure 5-2, one end of the reset member 2 can cooperate with the base 1, and the other end of the reset member 2 can cooperate with the protruding structure 5-2.

[0038] As a further optimization of this embodiment, the single-stage foot switch may further include an upper cover 7, a bolt hole may be opened on the surface of the upper cover 7, a waterproof plate 9 may be installed on the surface of the bolt hole, the upper cover 7 and the base 1 may be connected by bolts, a silicone pad 8 may be arranged between the upper cover 7 and the base 1, a convex ring 1-1 may be arranged on the upper surface of the edge where the base 1 and the upper cover 7 are connected, a groove 8-1 may be arranged on the bottom surface of the silicone pad 8, and the base 1 and the silicone pad 8 may be connected by the convex ring 1-1 and the groove 8-1; by arranging the silicone pad 8 between the upper cover 7 and the base 1, a sealed space is formed between the upper cover 7 and the base 1, thereby reducing the risk of contaminants entering the base 1 during surgery, and effectively increasing the waterproof performance of the equipment.

[0039] As a further optimization of this embodiment, the rear plate of the base 1 may be provided with a wire outlet hole 10, and the wire outlet hole 10 may be used to connect the cable 12. A silicone round pad 11 may be provided between the wire outlet hole 10 and the cable 12, and the surface of the cable 12 may be coated with an insulating waterproof tape 13; by providing a silicone round pad 11 between the wire outlet hole 10 and the cable 12 on the rear plate of the base 1, the risk of pollutants flowing into the device from the rear plate of the base 1 can be effectively avoided. In addition, by coating the surface of the cable 12 with the insulating waterproof tape 13, the service life of the cable 12 can be effectively increased, ensuring that even if pollutants flow into the interior of the device, no damage will be caused.
