Method for manufacturing a surgical saw blade with a blade head and raised boss around which the blade head pivots
First Claim
Patent Images
1. A method of assembling a surgical sagittal saw blade assembly having an oscillating blade head, said method including the steps of:
- providing a first plate;
punching out a portion of said first plate to form a boss, said boss having an outer wall that is at least partially circular and a top surface that is substantially perpendicular to said outer wall;
positioning a blade head on a distal end of said first plate, said blade head having a base that is disposed against said boss so as to be able to pivot around said outer wall of said boss and a crown located outside of said first plate, the crown being formed with teeth;
positioning at least one drive rod on said first plate, said at least one drive rod attached to said blade head; and
securing a second plate to said first plate to form a blade bar having an opening from which said blade head crown extends.

Abstract
In a method of assembling a surgical saw blade assembly with an blade bar that contains an oscillating head, the blade bar is formed from opposed plates. One of the plates is punch stamped to define a boss around which blade head pivots. The plates are secured to one another in a series of steps in which spaced apart sections of the plates are welded together.

11. A method of assembling a surgical sagittal saw blade having an oscillating blade head, said method including the steps of:
-
providing a first plate; providing a boss on said first plate, said boss having an outer wall that is at least partially circular and a top surface that is substantially perpendicular to said outer wall; positioning a blade head on a distal end of said first plate, said blade head having a base that is disposed against said boss so as to be able to pivot around said outer wall of said boss and a crown located outside of said first plate, said crown being formed with teeth; positioning at least one drive rod on said first plate, said at least one drive rod attached to said blade head; disposing an opposed second plate over said first plate, said blade head base and said at least one drive rod, said plates having opposed longitudinally extending sides; and welding said first and second plates together to form a blade bar, said blade bar having a distal end opening from which said blade head crown extends; wherein said welding step is performed by; forming at least one center weld between said plates, said center weld located inwardly of said opposed sides of said plates; and after said at least one center weld is formed, welding together a first section of adjacent surfaces on a first side of said plates;
welding together a first section of adjacent surfaces on a second side of said plates;
welding together a second section of adjacent surfaces on said first side of said plates; and
welding together a second section of adjacent surfaces on said second side of said plates. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
