Abstract: A milling module for converting bone stock into bone chips comprises a shell adapted for releasable attachment to a base module. The shell has an inlet opening through which bone stock is introduced into the shell and an outlet opening through which bone chips are discharged from the shell. A milling element is moveably disposed in the shell between the inlet opening and the outlet opening for converting bone stock into bone chips. The shell includes a base adapted for releasable attachment to the base module. The base includes the outlet opening and a lid removably attached thereto. The lid includes the inlet opening of the shell. The base and the lid are collectively configured so that removal of the lid from the base allows the milling element to be accessed.

Abstract: A milling module (60) for converting bone stock into bone chips comprises a shell (34) adapted for releasable attachment to a base module (32). The shell has an inlet opening (152) through which bone stock is introduced into the shell and an outlet opening (96) through which bone chips are discharged from the shell. A milling element (170) is moveably disposed in the shell between the inlet opening and the outlet opening for converting bone stock into bone chips. The shell includes abase (62) adapted for releasable attachment to the base module. The base includes the outlet opening and a lid (126) removably attached thereto. The lid includes the inlet opening of the shell. The base and the lid are collectively configured so that removal of the lid from the base allows the milling element to be accessed.

Abstract: A surgical saw blade cartridge includes a bar, a blade and a drive link. The bar includes a first plate and an opposed second plate defining a space therebetween, and an opening in at least one of the plates for releasable connection to a saw. The blade includes a base moveably disposed in the space between the plates and a head integral with the base located outside of the bar. The head has teeth at least as wide as a portion of the bar adjacent the head. The drive link extends through the bar and is moveable therein with a proximal end configured for attachment to a drive component of the saw and a distal end connected to either the base of the blade or a pivot link. The bar includes a structural member adjacent the head that extends forward of the head.

Abstract: 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.

Abstract: A cutting system including a surgical saw and a blade assembly is described. The blade assembly may comprising a blade bar, a blade head, and a tag. The tag may comprise a memory containing data related to one or more characteristics of the blade assembly. The surgical saw may comprise a saw processor for receiving data from the tag of the blade assembly and be configured to regulate the operation of the saw based on the one or more characteristics of the blade assembly. The one or more characteristic of the blade assembly comprises may comprise a blade assembly length, a blade geometry, and a blade teeth geometry. A method of navigating a surgical saw is also described. The method may comprise attaching a blade to the saw, touching a pointer to reference points on the blade, and determining the position and orientation of a distal end of the blade.

Abstract: A surgical saw blade is described comprising an elongated blade bar having opposed plates. The blade bar has opposed proximal and distal sections, with the proximal section having a feature for releasably holding the blade bar to a powered surgical sagittal saw. The blade bar plates are spaced apart from each other to form a void space and a primary opening into the void space. A blade head of the surgical saw blade has a base disposed in the blade bar distal section opening that is pivotally mounted in the blade bar distal section void space, and a crown integral with the base that extends through and outside of the blade bar distal section primary opening, the crown being formed with teeth, wherein a thickness of the crown is greater than a thickness of the base to allow the insertion of the blade bar into a kerf cut.

Abstract: A surgical sagittal saw with an indexing head. The saw actuates a blade assembly that includes a bar from which a blade head extends. An oscillating head extends upwardly from the saw head. The oscillating head, in addition is mounted to the saw head to be able to rotate around its longitudinal axis and so that it can move along the saw head. A biasing spring normally holds the oscillating head in a fixed position. When the oscillating head is in the fixed position, the oscillating head holds the blade assembly against a restraining bracket integral with the saw head. Manual force is used to overcome the biasing spring to allow replacement and removal of the blade assembly.
