Minimally invasive surgical driver
A method of removing bone material including the steps of drivingly connecting a bone removal tool to an output shaft; and rotating a plurality of drive shafts in an open frame, one of the plurality of drive shafts being connected to the output shaft.
1. A method of removing bone material, comprising the steps of:
drivingly connecting a bone removal tool to an output shaft; and
rotating a plurality of drive shafts in an open frame, said plurality of drive shafts include a first drive shaft, a second drive shaft, and a third drive shaft, said first drive shaft having a plurality of constraints apart from any driving connections with other drive shafts, said second drive shaft not having any constraints in contact with said second drive shaft other than driving connections with said first drive shaft and said third drive shaft, said third drive shaft being connected to said output shaft.
2. The method of claim 1 , wherein said open frame includes a side opening substantially along a length of said open frame, said open frame having two end openings that communicate with said side opening.
3. The method of claim 2 , further comprising the step of removably connecting a handle to an end of said open frame.
4. The method of claim 3 , wherein said handle is released from said frame by depressing a pushbutton.
5. The method of claim 1 , further comprising the step of drivingly connecting a self-aligning input shaft to one of said plurality of drive shafts.
6. The method of claim 5 , wherein said self-aligning input shaft includes one of an angled slot and a blade proximate an end of said self-aligning input shaft.
7. The method of claim 1 , wherein said first drive shaft is longer than said second drive shaft.
8. The method of claim 1 , wherein said plurality of drive shafts are in driving communication with an input shaft rotatable about a first axis, said output shaft being driven about a second axis, said first axis being offset from and substantially parallel to said second axis.
9. The method of claim 1 , further comprising the step of removably connecting a handle with an opening therethrough to said open frame.
10. The method of claim 9 , wherein said handle includes a pushbutton assembly that releases said handle from said open frame.
11. The method of claim 10 , wherein an input shaft is retained in said handle until being released by depressing said pushbutton assembly.
12. A method of removing bone material, comprising the steps of:
drivingly connecting a bone removal tool to an output shaft; and
rotating a plurality of drive shafts in an open frame, said plurality of drive shafts include a first drive shaft, a second drive shaft, and a third drive shaft, said first drive shaft having a plurality of constraints apart from any driving connections with other drive shafts, said second drive shaft not having any connections in contact with said second drive shaft other than driving connections with said first drive shaft and said third drive shaft, said third drive shaft being connected to said output shaft.
13. The method of claim 12 , wherein said open frame includes a side opening substantially along the length of said open frame, said open frame having two end openings that communicate with said side opening.
14. The method of claim 13 , further comprising the step of removably connecting a handle to an end of said open frame.
15. The method of claim 14 , wherein said handle is released from said frame by depressing a pushbutton.
16. The method of claim 12 , further comprising the step of drivingly connecting a self-aligning input shaft to one of said plurality of drive shafts.
17. The method of claim 16 , wherein said self-aligning input shaft includes one of an angled slot and a blade proximate an end of said self-aligning input shaft.
18. The method of claim 12 , wherein said first drive shaft is longer than said second drive shaft.
19. The method of claim 12 , wherein said plurality of drive shafts are in driving communication with an input shaft rotatable about a first axis, said output shaft being driven about a second axis, said first axis being offset from and substantially parallel to said second axis.
20. The method of claim 12 , further comprising the step of removably connecting a handle with an opening therethrough to said open frame.
