Patent ID: 7758608

Claim:
Manual actuating apparatus for operating a medical device having a common closable jaw for effecting operation of the medical device comprising: a handle; a finger loop mounted on the handle for receiving a finger of an operator; first and second lever members mounted on the handle for grasping engagement by other fingers of the operator, each of the first and second lever members being independently and pivotably mounted on the handle for movement between respective first and second positions wherein the first lever member extends between a mounted end pivotally attached to the handle and a free end and wherein the second lever member extends between a free end and a mounted end pivotally attached to the handle at a location intermediate the mounted end and the free end of the first lever member; an interengagement construction between the first lever member and the second lever member such that movement of one of the first or second lever members causes movement of the other one of the first or second lever member such that the first and second lever members move in a coordinated manner between the first and second positions; and a force transmitting member operably connecting at least one of the finger loop and the first and second lever members to the common closable jaw of the medical device for operating the common closable jaw at a location distant from the handle where movement of the first and second lever members between the first and second positions, relative to the finger loop, causes movement of the common closable jaw for opening and closing the common closable jaw of the medical device; whereby, in the course of operating the common closable jaw, the first and second lever members are positioned relative to the finger loop so that the operator can reposition the other fingers between the first and second lever members with rotation of the finger within the finger loop while operating the common closable jaw with the finger within the finger loop and thereby assure a comfortable hand posture throughout the complete range of operation of the medical device.
