  • Patent number: 7708758
    Abstract: The surgical instrument includes a distal tool, an elongated shaft that supports the distal tool, and a proximal handle or control member, where the tool and the handle are coupled to the respective distal and proximal ends of the elongated shaft via distal and proximal bendable motion members. Actuation means extends between said distal and proximal members whereby any deflection of said control handle with respect to said elongated instrument shaft causes a corresponding bending of said distal motion member for control of said working member. The proximal bendable member comprises a ball and socket assembly supported between the handle and instrument shaft and constructed and arranged for three dimensional motion.

  • Publication number: 20100106183
    Abstract: The surgical instrument includes a distal tool, a rigid or flexible elongated shaft that supports the distal tool, and a proximal handle or control member, where the tool and the handle are coupled to the respective distal and proximal ends of the elongated shaft via distal and proximal bendable motion members. Actuation means extends between said distal and proximal members whereby any deflection of said control handle with respect to said elongated instrument shaft causes a corresponding bending of said distal motion member for control of said working member. The proximal movable member comprises a movable ring assembly supported from the handle and adapted for three dimensional motion relative to the handle. A manually rotatable member may be arranged adjacent to the control handle for manually rotating the instrument shaft and working member relative to the control handle. A locking member may be supported from the control handle.

  • Patent number: 7699835
    Abstract: A robotically controlled surgical instrument includes a first jaw and a second jaw used to grasp an item, and a drive mechanism that increases the force applied to the item grasped. The drive mechanism and the jaws can be provided with an accommodating mechanism that allows continued movement of the drive mechanism towards a locked position even after the jaws contact a larger item so that the drive mechanism can move to the locked position when grasping items of different sizes.

  • Publication number: 20090299344
    Abstract: An instrument guide device comprises an elongated guide shaft having proximal and distal ends and including an instrument lumen for receiving therethrough a manually operated instrument having an instrument shaft. A distal bendable member is disposed at the distal end of the guide shaft and a proximal bendable member is disposed at the proximal end of the guide shaft. Actuation means extends between the distal and proximal bendable members and provides a bending of the distal bendable member controlled from the proximal bendable member. The proximal bendable member is controlled from the manually operated instrument to cause a corresponding bending of said distal bendable member. A locking mechanism has locked and unlocked positions and includes a ball and socket arrangement disposed about the proximal bendable member and a cinch member for locking the ball and socket arrangement.
