ABSTRACT:
The present surgical tool uses high frequency impulses to replace rotating or oscillating members in cutting through or inserting materials into bone. One embodiment comprises a chisel which uses high frequency impulses to remove bone or other hard material. Because of the high forces developed, a novel holder for the chisel to the tool is disclosed. Another embodiment is a wire driver which uses high frequency impulses to drive wire into bone or other tissue. A novel holder for the wire is disclosed which allows wire to be pulled from the tool so that it can be inserted into the bone but prevents wire from slipping back into the tool during the driving operation. The chisel and the wire are driven by a novel pneumatic impulse motor. The motor includes a piston hammer which is mounted in a chamber, and air ports at either end of the chamber alternately direct air to one side of the piston hammer and to the other side of the piston hammer to drive it along the chamber. A novel valve is provided to control the flow of air between air ports.
