Patent ID: 8114119

Claim:
A surgical grasping device, the device comprising: a clevis; a first jaw member pivotably coupled to the clevis; a second jaw member pivotably coupled to the clevis; an actuating mechanism coupled to the clevis, the first jaw member and the second jaw member, wherein the actuating mechanism comprises: a shuttle, wherein the shuttle is coupled to the first jaw member by a first coupling member, wherein the shuttle is coupled to the second jaw member by a second coupling member, and wherein a proximal portion of the shuttle is coupled to the translating member; a spring coupled to the shuttle and the clevis, wherein the spring is positioned to bias the shuttle distally; a spinner disk coupled to the proximal portion of the shuttle, wherein the spinner disk comprises a plurality of radial spines; a hollow upper insert to receive the spinner disk, wherein the upper insert defines a first plurality of pockets shaped to receive the plurality of radial spines to hold the spinner disk in a distal position and a second plurality of pockets shaped to receive the plurality of radial spines to hold the spinner disk in a proximal position; and a translating member coupled to and extending proximally from the actuating mechanism, wherein the actuating mechanism is configured to cause the first jaw member and the second jaw member to close in response to a first proximally directed force received via the translating member, and wherein the actuating mechanism is also configured to cause the first jaw member and the second jaw member to open in response to a subsequent proximally directed force received via the translating member.
