Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to a multifunctional foot pedal device. Background Technology

[0002] A foot switch is a switch that operates by stepping on or off a circuit or signal. It is used in control circuits where the hands cannot reach, replacing or freeing up the hands for operation. In the field of ophthalmology, doctors need to constantly adjust various treatment parameters during laser eye treatment of patients. Since the hands cannot simultaneously adjust multiple parameters, a foot switch allows doctors to use their feet for quick and accurate laser control. However, existing foot switches are either single-function (only able to switch one device), have an unreasonable multi-switch structure (prone to accidental activation), or are uncomfortable to operate, leading to misoperation. Therefore, a foot switch with a reasonable structure and multiple switching capabilities is needed. Utility Model Content

[0003] This utility model provides a multifunctional foot pedal device to realize a foot pedal switch with multiple switches and convenient operation.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A multifunctional foot pedal device includes a pedal with a foot pad area and a switch area. The switch area has a foot switch for controlling laser output and shutting it off. One or both sides of the foot switch have micro-trigger devices for adjusting laser properties.

[0006] Furthermore, the upper surface of the foot pad area is provided with a textured first flexible pad for contact with the sole of the foot.

[0007] Furthermore, the lower surface of the pedal is provided with a textured second flexible pad for contacting the ground.

[0008] Furthermore, the switch area is provided with a foot protection panel, which is connected to the pedal and is used to protect the foot switch; the micro trigger device is fixed inside the foot protection panel.

[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] like Figure 1-3 As shown, a multifunctional foot pedal device includes a pedal 1. The pedal 1 is made of SPCC material (steel-plate-cold-common, generally made of cold-rolled carbon steel sheet and steel strip) to increase the weight of the pedal 1 and prevent the pedal 1 from moving easily after being subjected to force.

[0029] The pedal 1 has a footrest area 2 and a switch area 3. The footrest area 2 is used to support the ball of the foot or heel. During operation, doctors mainly move and operate the foot by using the heel as a fulcrum. However, conventional foot switches 6 do not have a structure for heel placement, only a switch for stepping. Because of the lack of positioning for the foot switch 6, doctors need to frequently look down to check if their foot is stepping correctly. The footrest area 2 of this invention can achieve foot positioning. The footrest area 2 has a structure for positioning and is different from the ground, such as a raised structure, similar to the structure of tactile paving; or it can make the footrest area 2 relatively soft compared to the ground, that is, the footrest area 2 has a first flexible pad 4, or the bottom of the pedal 1 has a second flexible pad 5. The first flexible pad 4 and the second flexible pad 5 can be made of flexible pads such as rubber pads, silicone pads, and latex pads.

[0030] The first flexible pad 4 is used to support the heel. Its horizontal textured design provides greater friction and prevents slipping. The first flexible pad 4 is detachably mounted to the pedal 1 via a plug-in or slot-like structure, allowing for different height adjustments. This adjusts the height difference between the foot pad area 2 and the switch area 3, allowing the doctor to control the pedal in a comfortable, raised position, avoiding foot numbness caused by prolonged, excessive raised feet. The second flexible pad 5 contacts the ground and features a vertical textured design, increasing lateral friction between the pedal 1 and the bottom surface. This ensures the stability of the pedal 1 when the user kicks the micro-motion button to activate the pedal 8, preventing rotation or lateral tilting.

[0031] The switch area 3 is used to house the switch assembly and electrical components. A foot switch 6 for controlling laser output and shutdown is provided within the switch area 3. Micro-trigger devices 7 for adjusting laser properties are provided on one or both sides of the foot switch 6. Based on the needs and habits of doctors, the number of times the laser is turned on and off is generally greater than the number of times it is adjusted. Therefore, this invention places the foot switch 6 controlling the laser's on / off state in the middle, triggered by a simple vertical foot press. Foot switches 6 for laser adjustment functions, which require fewer foot presses, are placed on either side, triggered by a horizontal press with foot rotation. This invention rationally allocates resources based on the characteristics of human foot movement and laser control, minimizing foot fatigue during control and thus avoiding control errors. Preferably, micro-trigger devices 7 are provided on both sides of the foot switch 6. The micro-trigger device 7 on one side controls the increase of the laser power, while the micro-trigger device 7 on the other side controls the decrease. For example, the micro-trigger devices 7 on both sides control the increase and decrease of the laser power, respectively.

[0032] The micro-trigger device 7 described in this invention is positioned higher than the foot switch 6 in a horizontal direction parallel to the ground, creating a slight height difference between the two. When the micro-trigger device 7 needs to be pressed, the user needs to slightly lift the ball of their foot and then rotate it horizontally to trigger the switch. This design is to prevent the user from accidentally touching the micro-trigger device 7 when pressing the foot switch 6.

[0033] like Figure 4 As shown, the micro-trigger device 7 includes a trigger pedal 8 and a micro-touch switch 9. The trigger pedal 8 is provided with a force-receiving end and a trigger end. One side of the force-receiving end is connected to the trigger end, and the trigger end contacts the trigger button of the micro-touch switch 9. When the force-receiving end is squeezed, the trigger end presses the trigger button as the force-receiving end is squeezed. When the trigger button is pressed and subjected to force, the laser power is adjusted.

[0034] like Figure 5 As shown, the trigger pedal 8 is made of metal and preferably has a Z-shaped cross-section in the horizontal direction, consisting of a trigger end 10 and a force-receiving end 11. The trigger end 10 and the force-receiving end 11 have a certain thickness difference in space, which is more conducive to triggering. The trigger end 10 is elongated, which helps to provide a larger deformation range. Two screw holes are opened at the front end of the trigger end 10 for fixing with the micro switch. The area of ​​the force-receiving end 11 is larger than that of the trigger end 10, providing a larger force-receiving area and making the force more even. Preferably, the trigger end 10 and the force-receiving end 11 form an L-shaped cross-section in the direction perpendicular to the ground. During installation, the position of the force-receiving end 11 in the direction perpendicular to the ground is closer to the foot switch 6, while the trigger end 10 is farther away from the foot switch 6. Preferably, the force-bearing end 11 has folded edges around the force-bearing surface to increase the overall stability of the force-bearing part 11, reduce its deformation, and allow the force-bearing end 11 to move as a whole in the direction of the force after being pressed. Simultaneously, it transmits the displacement to the trigger end 10 to the maximum extent. The trigger end 10 deforms to trigger the trigger button of the micro switch. After the force is applied, the trigger end 10 can return to its initial state due to the elastic deformation of the metal material, thus enabling the micro switch 9 to be continuously triggered. This invention can also provide a return spring between the trigger end 10 and the trigger button of the micro switch 9 to improve the stability of the restoring force of the trigger end 10.

[0035] A foot protection panel 12 is provided on the pedal 1 within the switch area 3. The foot protection panel 12 is a four-sided cover, preferably a snap-on type, used to protect electronic components and circuitry. Furthermore, the internal structure and wiring are not visible from the front of the device, contributing to its aesthetic appeal. After being connected to the pedal 1, the foot protection panel 12 has only one opening for a foot to enter. The micro-trigger device 7 is fixed to the inner side wall of the foot protection panel 12. The top of the foot protection panel 12 also has a U-shaped groove for easy gripping during transport.

[0036] The outer side of the foot pedal protective panel 12 is equipped with a laser adjustment button 13 and a laser status indicator light. Stepping on the laser adjustment button 13 can switch between different laser states. At the same time, the indicator light displays different colors to indicate different laser states, making it easy for users to understand the current status. The indicator light is also designed to facilitate operation by doctors in a dark room environment.

[0037] The inside of the snap-on foot pedal protective panel 12 is provided with a cavity 14 for hiding the connecting wires, preferably in a cross or T shape, to facilitate the concealment and protection of the wiring of the foot switch 6, micro trigger device 7, laser adjustment button 13 and laser status indicator.

[0038] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
