Abstract

A bone fixation system is provided. The bone fixation system may include a plate, one or more fasteners configured to attach the plate to a target anatomical location such as bone, and a surgical device that facilitates the attachment of the plate and the fasteners.

Claims (38)

1. A method of fixing a surgical fastener to a target anatomical location, the method comprising steps of:

directing a laser of a cutting mechanism of a surgical device toward the target anatomical location so as to cut a hole in the target anatomical location;

advancing the surgical fastener into the hole of the target anatomical location as the surgical fastener is supported by the surgical device;

activating an energy source of the surgical device to thereby heat and soften at least a portion of the surgical fastener so as to attach the surgical fastener to the target anatomical location; and

removing the surgical device while the surgical fastener remains attached to the target anatomical location.

2. The method according to claim 1 , wherein:

the cutting step includes:

placing a polymer based bone plate on the target anatomical location;

cutting a hole through the plate and into the target anatomical location by using the cutting mechanism of the surgical device; and

the removing step comprises removing the surgical device while the surgical fastener and plate remain attached to the target anatomical location.

3. The method according to claim 1 , further comprising:

pressing the surgical fastener into the hole in the target anatomical location during heating and softening of the portion of the surgical fastener.

4. The method according to claim 1 , comprising heating the surgical fastener to such a degree that the fastener becomes at least partially deformable.

5. The method of claim 1 , wherein the advancing step comprises advancing the surgical fastener into the hole as the cutting mechanism cuts the hole.

6. The method according to claim 1 , wherein the activating step comprises transmitting electromagnetic radiation from the energy source to the surgical fastener.

7. The method according to claim 6 , wherein the activating step comprises transmitting the electromagnetic radiation through a transmissive portion of the surgical fastener to the portion of the surgical fastener.

8. The method of claim 7 , wherein the activating step comprises transmitting the electromagnetic radiation through a core that defines the transmissive portion to an external surface of the surgical fastener that defines the portion.

9. The method of claim 7 , wherein the activating step comprises transmitting the electromagnetic radiation through a proximal end of the surgical fastener that defines the transmissive portion to a distal end of the surgical fastener that defines the portion.

10. The method of claim 1 , comprising a step of inserting the cutting mechanism into a bore that extends into a body of the surgical fastener such that the cutting mechanism supports the surgical fastener.

11. The method of claim 1 , wherein the activating step comprises heating the surgical fastener with a laser of the energy source, the laser of the energy source being different from the laser of the cutting mechanism.

12. The method of claim 11 , wherein the directing step comprises directing one of a 3 μm infrared laser, a 10 μm CO 2 laser, and a 2.8 μm Erbium YAG laser toward the target anatomical location.

13. The method of claim 11 , the activating step comprises heating the surgical fastener with a 800 nm laser.

14. The method of claim 1 , further comprising injecting an irrigation fluid into a recess in the surgical fastener as the cutting mechanism cuts the hole so as to remove debris from the hole.

15. A method of fixing a surgical fastener to a target anatomical location, the method comprising steps of:

extending a cutting mechanism of a surgical device through a bore of the surgical fastener;

cutting a hole in the target anatomical location as the cutting mechanism extends through the bore of the surgical fastener;

advancing the surgical fastener into the hole of the target anatomical location as the surgical fastener is supported by the surgical device and as the cutting mechanism is cutting the hole;

activating an energy source of the surgical device to thereby heat and soften at least a portion of the surgical fastener so as to attach the surgical fastener to the target anatomical location; and

removing the surgical device while the surgical fastener remains attached to the target anatomical location.

16. The method according to claim 15 , wherein:

the cutting step includes:

placing a polymer based bone plate on the target anatomical location;

cutting a hole through the plate and into the target anatomical location with the cutting mechanism of the surgical device; and

the removing step comprises removing the surgical device while the surgical fastener and plate remain attached to the target anatomical location.

17. The method of claim 15 , wherein the extending step comprises extending a first optical waveguide through the bore.

18. The method of claim 17 , wherein the cutting step comprises directing a laser of the cutting mechanism of the surgical device toward the target anatomical location so as to cut the hole in the target anatomical location.

19. The method of claim 15 , wherein the activating step comprises heating the surgical fastener with a laser of the energy source.

20. The method according to claim 15 , wherein the activating step comprises transmitting electromagnetic radiation through a transmissive portion of the surgical fastener to the portion of the surgical fastener.
