Abstract
A surgical sagittal saw cartridge that includes a guide bar formed from an inner plate and opposed outer plates, the inner plate defining a head. The cartridge has a blade that is disposed against the head of the inner plate. The inner plate may comprise an inner tine and/or two opposed outer tines. The inner tine may be formed to define the head against which the blade is disposed. The outer tines may extend distally so as to define a space between the outer tines in which the blade is seated.
Claims10
A surgical saw cartridge for oscillating a blade, the surgical saw cartridge comprising:
- a guide bar including a proximal end and a distal end, the guide bar comprising:
- two outer plates;
- and
- an inner plate located between the two outer plates, the inner plate defining a base at the proximal end of the guide bar;
- an outer tine disposed between the two outer plates, the outer tine extending distally from the base;
- an inner tine extending distally from the base, the inner tine being disposed between the two outer plates and formed to define a head;
- a blade coupled to the guide bar, the blade formed with teeth located distal to the guide bar and the blade configured to contact and pivot about the head of the inner tine;
- and
- at least one drive link moveably disposed between the two outer plates within a space between the inner tine and the outer tine, the at least one drive link having opposed proximal and distal ends, the proximal end of the at least one drive link adapted to be attached to a drive element of a saw and the distal end of the at least one drive link being connected to the blade so that reciprocation of the at least one drive link results in pivoting of the blade around the head of the inner tine.
