Abstract

Disclosed are embodiments of an articulating tool having a head that articulates and is capable of maintaining an angle for drilling or placing a fastener into a bone. The articulating tool includes a housing, an articulating head, a rotatable drive shaft, and a driver tip connected to the distal shaft portion. The articulating tool may be constructed and arranged to move between a first position and a second position, wherein in the first position and the second position the articulating head and the rotatable drive shaft are at different angles with respect to the longitudinal axis of the housing.

Claims

1. A method of fastener installation, the method comprising:

positioning a head of an articulating tool in a thoracic cavity under thoracoscopic guidance, the head holding a fastener, the thoracic cavity being surrounded by a chest wall that includes a rib bone;

driving the fastener into an inner side of the rib bone from the thoracic cavity with the articulating tool; and

removing the head of the articulating tool from the thoracic cavity after the step of driving, while the fastener remains in the rib bone.

2. The method of claim 1, wherein the step of driving the fastener includes a step of affixing an osteosynthetic implant to the rib bone with the fastener.

3. The method of claim 2, wherein the osteosynthetic implant is an osteosynthetic plate.

4. The method of claim 2, further comprising a step of inserting the osteosynthetic implant into the thoracic cavity under thoracoscopic guidance.

5. The method of claim 4, further comprising a step of contouring the osteosynthetic implant to the rib bone after the step of inserting the osteosynthetic implant.

6. The method of claim 1, further comprising a step of drilling a hole in the rib bone from the thoracic cavity by application of torque to a drive shaft of the articulating tool.

7. The method of claim 6, wherein the step of drilling a hole is performed with a drill bit operatively connected to the drive shaft of the articulating tool, further comprising a step of replacing the drill bit with the fastener before the step of driving the fastener.

8. The method of claim 1, further comprising a step of introducing the head of the articulating tool into the thoracic cavity through an incision in the thorax.

9. The method of claim 1, wherein the step of positioning a head of an articulating tool includes a step of pivoting the head about an axis transverse to the articulating tool, and wherein the transverse axis is defined by a pivotable joint that connects the head to a discrete housing of the articulating tool.

10. The method of claim 1, wherein the fastener is selected from the group consisting of a screw, a nail, and a staple.

11. The method of claim 1, wherein the step of driving the fastener includes a step of rotationally driving the fastener into the rib bone by application of torque to a drive shaft of the articulating tool.
