Surgical Sagittal Blade Cartridge

A surgical saw system, the system comprising:

• a surgical device including a mount, the mount defining a mount surface, and the mount comprising:
• a coupling post;
• and
• an alignment post;
• a saw blade cartridge removably couplable to the mount of the surgical device, the saw blade cartridge comprising:
• a guide bar including a distal portion and a proximal portion, the guide bar comprising:
• an inner plate defining a pivot surface, a first opening, and a second opening;
• a blade disposed at a distal end of the guide bar, the blade having a blade body defining a pivot face to pivot about the pivot surface of the inner plate;
• wherein the first opening is sized to receive and slidably engage the alignment post of the mount to axially align the saw blade cartridge relative to the surgical device;
• and
• wherein the second opening is sized to receive the coupling post of the mount to removably couple the saw blade cartridge to the surgical device.

A surgical sagittal saw blade cartridge for use with a surgical device, the saw blade cartridge comprising:

• a guide bar including a distal portion and a proximal portion, the guide bar comprising:
• a first plate;
• a second plate;
• and
• an inner plate disposed between the first and the second plates, the inner plate defining a pivot surface, a first opening, and a second opening;
• a longitudinal axis extending between the distal portion and the proximal portion of the guide bar;
• a blade at least partially disposed between the first plate and the second plate at a distal end of the guide bar, the blade having a blade body defining a pivot surface to pivot about the pivot surface of the inner plate;
• wherein the first opening having opposed lateral surfaces, the first opening being centered on the longitudinal axis;
• and
• wherein the combination of the first opening and the second opening of the inner plate are configured to axially align the saw blade cartridge relative to the surgical device.
