Abstract
An orthopedic impacting tool comprises a motor, a linear motion converter, an air chamber, a compression piston, a striker, a detent and a broach adapter. The compression piston may cause the striker to apply controlled force on a adapter to create a precise opening for subsequently disposing a prosthesis in a patient. The detent may hold the striker in a position until a sufficient pressure is applied to release the striker. The tool allows forward or backward impacting for expanding the size or volume of the opening or for facilitating removal of the broach and tool from the opening. A force adjustment control of the tool allows a user to increase or decrease the impact force. A light source and hand grips improve ease of operation of the tool.
Claims19
An orthopedic impacting tool for striking an object, the tool comprising
- a motor,
- a linear motion converter,
- a compression piston operatively coupled to said linear motion converter, said piston having a first end and a second end,
- an air compression chamber,
- a striker,
- a detent for retaining the striker in a position,
- a control means,
- an anvil element,
- an adapter capable of holding a broach, chisel, reamer, or other surgical implement, said adapter operatively coupled to said anvil element, and
- a hand grip,
- wherein said control means directs said motor to move said linear motion converter and causes said compression piston to move and compress or decompress air within said air chamber, and
- wherein when said compressed air exceeds the retention force of the detent the striker moves from a first position to a second position, striking said anvil element,
- such that the striker imparts a force upon the adapter in at least one direction.

- an adapter capable of holding a broach, chisel, reamer, or other surgical implement, said adapter operatively coupled to said anvil element, and
- a hand grip,
- wherein said control means directs said motor to move said linear motion converter and causes said compression piston to move and compress or decompress air within said air chamber, and
- wherein when said position of compression piston contacts said nosepiece of said striker with force that exceeds the retention force of the detent said striker moves from a first position to a second position, striking said anvil element,
- such that the striker imparts a force upon the adapter in at least one direction.
