Abstract
A device for inserting implants comprises an elongate, hollow shank with a gripping head at one end to grip and hold an implant. The gripping head includes a movable jaw operatively connected to a drive shaft such that rotation of the drive shaft causes the movable jaw to move. The drive shaft may include a gear that meshes with integrally formed teeth on the movable jaw. The drive shaft is axially movable between locked and unlocked positions.
Claims32
A device for inserting an implant into a body comprising:
- a shank;
- a gripping head at one end of the shank for gripping the implant, the gripping head including a movable jaw and a fixed jaw to engage and hold the implant;
- an actuating mechanism operatively connected to move the movable jaw, the actuating mechanism including a rotatable member that is axially movable between locked and unlocked positions;
- wherein in the unlocked position, rotation of the rotatable member causes the movable jaw to move;
- wherein in the locked position, rotation of the rotatable member is prevented to lock the movable jaw in place;
- wherein the rotatable member comprises a drive shaft operatively connected with the movable jaw such that rotation of the drive shaft about a longitudinal axis causes the movable jaw to move;
- and
- wherein the actuating mechanism further comprises a rotatable control knob disposed at one end of a handle and connected to the drive shaft such that rotation of the control knob rotates the drive shaft.
A device for inserting an implant into a body comprising:
- a shank;
- a gripping head at a distal end of the shank for gripping the implant, the gripping head including a movable jaw to engage and hold the implant;
- a drive mechanism including a flexible drive shaft rotatable about a longitudinal axis and having a drive gear at one end operatively connected with the movable jaw such that rotation of the drive shaft about the longitudinal axis causes the movable jaw to move;
- and
- wherein the actuating mechanism further comprises a rotatable control knob disposed at one end of a handle and connected to the drive shaft such that rotation of the control knob rotates the drive shaft.
