Patent attributes
Manual actuating apparatus for operating a medical device includes a handle, a finger loop mounted on the handle for receiving the thumb of an operator, first and second lever members mounted on the handle for grasping engagement by fingers of the operator, at least one of the lever members and the finger loop being pivotally mounted on the handle for movement between first and second positions. A force transmitting member operably connects at least one of the finger loop and the first and second lever members for operating the medical device at a location distant from the handle such that, in the course of operating the medical device, the operator can reposition his fingers between the first and second lever members with rotation of his thumb within the finger loop and thereby assure a comfortable hand posture throughout the complete range of operation of the medical device.
