Abstract

The invention relates to a medical foot pedal applied to every medical equipment as a user interface to control motion. The medical foot pedal utilizes ingenious combination of metal cavity characteristics and a micro switch as well as spring to achieve final function. A pedal bracket connects the foot pedal with a fixed frame and the pedal rotate around the pedal bracket. The foot pedal includes a shaft which plays important role as adapting piece between the pedal and pedal bracket, a reset spring which allow pedal to return back to original position as well as a micro switch utilized to transmit signal to controller. When an operator steps on the foot pedal, the micro switch is triggered and switches on pedal circuit.

MEDICAL FOOT PEDAL

FIELD OF INVENTION

The invention generally relates to an X-ray system and more particularly to a medical foot pedal in the X-ray system.

BACKGROUND OF THE INVENTION


In an X-ray system a foot pedal is utilized to control motion of medical equipments. The foot pedal is prone to debris or dust which easily stuck trigger of the pedal. There is erosion risk of mechanical parts, specifically, when there is liquid leakage into the pedal. Further, over stroke of pedal damages switch and noise of click arises from pedal operation. Also, there is lower reliability from mechanism due to optical sensor used.


A conventional technique includes an operation system with a controller that controls a plurality of medical devices and a footswitch. The footswitch includes a selection unit capable of selecting a medical device to be used and an output of the medical device. The footswitch further includes pedals for instructing the selected medical device to perform the output. The controller includes a memory unit that stores output pedal setting information comprising operator identification information, first pedal setting information and second pedal setting information and a control unit. The conventional foot pedal is sealed up enough to avoid erosion. However, the mechanical structure of foot pedal lacks stiffness and it has low reliability of the mechanism.

Hence there exists a need for an efficient technique for providing mechanical stability to the foot pedal in the X-ray system.

BRIEF DESCRIPTION OF THE INVENTION

The invention relates to a medical foot pedal, which is applied to every medical equipments as a user interface to control motion. A pedal bracket connects the foot pedal with a fixed frame and the pedal rotate around the pedal bracket. The foot pedal includes a shaft which plays important role as adapting piece between the pedal and pedal bracket, a reset spring which allows pedal to return back to original position and a micro switch utilized to transmit signal to a controller.
