Orthopedic impactor attachment
View Patent ↗The present invention relates to a portable medical drill impact attachment device. The device can be used for improving the accuracy and reliability of orthopedic surgeries and procedures by obviating a manual device such as a hammer for creating an impact. The attachment device is used for creating impact forces that can be transferred onto a bone, disc, joint, etc. The device features a housing that includes a rotary motion transformer and an impact mechanism assembly. The attachment transforms the rotational motion of a drill into reciprocal motion, and also enables a user to adjust and control the frequency and energy of the impact. An impactor tool can be detachably-attached to a quick-change tool gripper for providing an impact on a bone, disc or joint of a patient without applying any manual force.

a housing comprising a quick-change tool gripper mechanism at a distal end, a rotary motion converting mechanism at a proximal end, and an adjustable impacting mechanism therebetween;
wherein said housing further comprises a drill attachment at said proximal end;
wherein said rotary motion converting mechanism transforms a rotational motion into a reciprocal motion to said adjustable impacting mechanism;
wherein said drill attachment is securable to a drill for providing said rotational motion;
wherein said quick-change tool gripper mechanism comprises an impact tool change gripper to which a first impactor tool can be selectively attached;
a switch disposed along said housing for varying an impact power of said adjustable impacting mechanism; and
wherein said rotary motion converting mechanism comprises a linear motion shaft and a linear bushing for transmitting said rotational motion to a crank.
2. The orthopedic impactor device of claim 1 , wherein said switch is rotatable in both a clockwise direction and a counter-clockwise direction for said varying of said impact power of said adjustable impacting mechanism.
3. The orthopedic impactor device of claim 2 , wherein said varying of said impact power includes modifying a compression rate of a wave spring in said adjustable impacting mechanism.
4. The orthopedic impactor device of claim 3 , wherein said wave spring comprises a coiled flat stainless-steel wire.
5. The orthopedic impactor device of claim 2 , wherein said varying of said impact power includes adjusting a tension of a wave spring in said adjustable impacting mechanism.
6. The orthopedic impactor device of claim 2 , wherein said varying of said impact power includes modifying a frequency rate of said adjustable impacting mechanism.
7. The orthopedic impactor device of claim 6 , wherein said housing is comprised of an anodized aluminum.
8. The orthopedic impactor device of claim 1 , wherein said crank reciprocates a shaft for actuating a first anvil and a second anvil.
9. The orthopedic impactor device of claim 8 , wherein said first anvil slides linearly forward and backward in said housing.
10. The orthopedic impactor device of claim 9 , further comprising at least a second impactor tool for selective attachment to said quick-change tool gripper mechanism.
11. An orthopedic impactor device comprising:
a housing comprising a quick-change tool gripper mechanism at a distal end, a rotary motion converting mechanism at a proximal end, and an adjustable impacting mechanism therebetween;
