Methods and devices for utilizing bondable materials
The invention primarily relates to fastening and stabilizing tissues, implants, and/or bondable materials, such as the fastening of a tissue and/or implant to a bondable material, the fastening of an implant to tissue, and/or the fastening of an implant to another implant. This may involve using an energy source to bond and/or mechanically to stabilize a tissue, an implant, a bondable material, and/or other biocompatible material. The invention may also relate to the use of an energy source to remove and/or install an implant and/or bondable material or to facilitate solidification and/or polymerization of bondable material.
1. A method of utilizing a bondable material to secure a fastener, said method comprising:
engaging an end effector with at least a trailing end of the fastener;
positioning a leading end feature of the fastener in direct contact with a surface of the bondable material, wherein the bondable material is in a fixed position;
applying energy to the fastener to heat and melt at least a portion of the bondable material in contact with the leading end feature of the fastener;
applying force to the fastener during the application of energy to the fastener to form an opening through the surface of the bondable material and embed at least a portion of the fastener within the bondable material to secure the fastener within the bondable material; and
disengaging the end effector from the trailing end of the fastener.
2. The method of claim 1 further comprising retaining force on the fastener after the application of energy to allow the bondable material to cool and harden.
3. The method of claim 1 wherein at least a portion of the fastener is mechanically interlocked within the bondable material.
4. The method of claim 1 wherein the bondable material is a solidified polymer before the application of energy.
5. The method of claim 1 wherein at least a portion of the bondable material flows into at least one surface feature of the fastener to secure the the fastener to the bondable material.
6. The method of claim 1 wherein leading end feature of the fastener is a taper.
7. The method of claim 1 wherein at least a portion of the fastener comprises at least one of titanium, stainless steel, and cobalt-chrome alloy.
8. The method of claim 1 wherein the fastener is internally threaded.
9. The method of claim 8 further comprising securing a second fastener having external threads to the fastener embedded in the bondable material.
10. The method of claim 1 wherein the fastener includes at least a portion of titanium and at least a portion of a polymer.
11. The method of claim 1 wherein the energy is at least one of vibratory energy, ultrasonic energy, radiofrequency energy, microwave energy, laser energy, electromagnetic energy, and resistive heating.
12. The method of claim 1 wherein the fastener remains solid when embedded within the bondable material.
13. The method of claim 1 wherein the bondable material is bone cement.
14. The method of claim 1 wherein the fastening implant is positioned relative to a supporting element.
15. A method of securing a fastener in a bondable material, said method comprising:
positioning a leading end of a fastener in direct contact with a portion of the bondable material, wherein the bondable material is in a fixed position;
applying ultrasonic energy to the fastener to melt the portion of the bondable material in contact with the leading end of the fastener; and
applying force to the fastener during the application of energy to the fastener to form an opening in the bondable material and embed at least a portion of the fastener within the bondable material.
16. The method of claim 15 wherein the fastener is mechanically interlocked within the bondable material.
17. The method of claim 15 further comprising retaining force on the fastener after the application of ultrasonic energy to allow the bondable material to cool and harden.
18. The method of claim 15 wherein the fastener is internally threaded.
19. The method of claim 18 further comprising securing a second fastener having external threads to the fastener embedded in the bondable.
20. The method of claim 15 wherein the fastener is engaged with an end effector prior to the application of ultrasonic energy and the end effector is disengaged from the fastener after the fastener is embedded within in a hole in the bondable material.
