A surgical saw system including a saw, a blade cartridge and an attachment. The saw including a housing and a reciprocating shaft. The blade cartridge that may be removably coupled to the saw includes a bar and a rack. The bar includes a first holding feature. The rack is moveably disposed within the bar and is configured to removably couple to the reciprocating shaft of the saw. The attachment is disposed between and connecting the bar of the blade cartridge to the saw. The attachment may include a coupling feature in selective releasable engagement with the first holding feature of the bar to hold the bar static relative to the saw. The blade cartridge may also include a drive link that extends from reciprocating shaft of the saw and the rack for imparting the reciprocal motion of the reciprocating shaft to the rack.

Surgical saw system including a reciprocating saw blade cartridge

The present disclosure relates generally to a surgical system. The surgical system comprises one or more surgical instrument assemblies and a surgical navigation system. The surgical instrument assemblies comprises a tracking device capable of being tracked by the surgical navigation system. The surgical system is also configured to allow the user to define one or more alert zones relative to anatomical structures of the patient and/or a surgical pathway. The surgical system further comprises an alert device in communication with the surgical navigation system, such that the alert device is configured to provide a user-perceptible alert to the surgeon or medical professional based on the position of the surgical instrument, as determined by the surgical navigation system, relative to the defined alert zones and/or surgical pathway.

Surgical navigation systems and methods

A surgical saw system including a saw, a blade cartridge and an attachment. The saw including a housing and a reciprocating shaft. The blade cartridge that may be removably coupled to the saw includes a bar and a rack. The bar includes a first holding feature. The rack is moveably disposed within the bar, and is configured to removably couple to the reciprocating shaft of the saw. The attachment is disposed between and connecting the bar of the blade cartridge to the saw. The attachment may include a coupling feature in selective releasable engagement with the first holding feature of the bar to hold the bar static relative to the saw. The blade cartridge may also include a drive link that extends from reciprocating shaft of the saw and the rack for imparting the reciprocal motion of the reciprocating shaft to the rack.

A blade cartridge for use with a surgical saw includes a bar and a rack. The bar includes a first holding feature for removably holding the bar static to the saw. The rack includes a base moveably disposed in the bar and has cutting teeth defining extending beyond the bar. A drive link extends from the base, providing a second holding feature for releasably engaging a reciprocating drive integral with the saw. One of the base and the bar includes a guide slot. The other of the base and the bar includes a static member extending into the guide slot. The guide slot and the static member allow the rack to reciprocally move from proximal to distal to proximal along a longitudinal axis of the bar. The bar includes two plates and a spacer between the plates. The base is located between the plates.
