Electrical plug for supplying electric power from a power supply to a medical instrument
First Claim
1. A connector for medical instruments adapted to be rendered active upon receipt of electric power from a power supply to allow a treating operation to be performed on a subject wherein the connector is removably attachable to a socket having a first electrode to allow the electric power to be supplied to the medical instrument and wherein the connector comprises:
- a projection protruding in a moving direction in which the medical instrument is connected to the socket electrically connected to the power supply;
a second electrode electrically connectable to the first electrode wherein an exposed contact portion of the second electrode is formed as an elongated portion that extends along the moving direction, the exposed contact portion being located peripherally around the projection; and
a connector shell extending in the moving direction, about and spaced away from the projection in a manner that forms a groove therebetween.
