| 摘要 |
The present invention provides a foot control unit having a plurality of switches for use by a dentist, surgeon, or other professional that is ergonomically designed to minimize body movement during activation and to prevent interruptions of the procedure being performed that may be caused by the same. In one exemplary embodiment, the design provides for the operator's, e.g., the dentist's, foot to be continuously and comfortably supported in a neutral muscular-skeletal position by a portion of the foot control unit both at rest and during activation. By providing the foot with a neutral muscular-skeletal position at rest, the position of each of the switches may be kept at a substantially minimal and substantially equal distance from a corresponding activating part of the foot. This allows for the foot control unit of the present invention to minimize muscular activities and movement during activation. |
