Medical devices and related methods for transforming bone, other tissue, or other material are disclosed herein. According to an aspect, a cutting device includes a static casing having a width of substantially a first distance. The cutting device also includes a blade working body including a first end and a second end. The first end is configured to operatively connect to a source of movement. The second end includes a cutting component. The blade working body has a width of substantially a second distance, wherein the second distance is greater than the first distance.

The present invention relates to a cutting device (1) for surgical or dental use, comprising a motor (10) connected to a handpiece (4) provided with a transmission module (2) for a cutting tool (3), the transmission module (2) comprising: a motor coupling part arranged to be set in rotation by the said motor (10); a kinematic chain transforming the rotary movement of the motor (10) into a first linear reciprocating movement (M1) of a blade holder (27) via a rotary transmission shaft (22) provided with an eccentric (23),

the transmission module (2) being characterized in that it further comprises a counter-mass (5) arranged so as to move according to a second linear reciprocating movement (M2) synchronized with the first linear reciprocating movement (M1) of the blade holder (27), and in the opposite direction to the latter.

A surgical saw blade for being coupled to a drive hub of a surgical saw. The surgical saw blade includes an attachment portion configured to be removably coupled to the drive hub. The surgical saw blade also includes a cutting portion opposite the attachment portion that includes a plurality of teeth. Additionally, the attachment portion defines a pair of indents. The first indent and the second indent are each defined by at least one curved surface. The curved surface is radially outwardly convex.

A surgical saw and complementary blade. The blade has lock teeth that are more ductal than the cutting teeth. The saw coupling assembly has an anvil and a press. The saw coupling assembly holds the blade to the saw by compressing the saw lock teeth between the anvil and the press so as to result the coining of the lock teeth.

A surgical preparation tool for preparing a sacroiliac joint for a surgical procedure comprising a trial tool assembly and a cutting tool configured to releasably and slidably couple with the trial tool assembly, wherein the trial tool assembly is configured to guide the cutting tool during distal-proximal translation such that as the cutting tool distally advances relative to an implant trial of the trial tool assembly, at least a portion of a cutting element of the cutting tool extends generally over and perpendicularly outward from a first top surface of a body of the implant trial.

An accessory for an oscillating power tool is provided. The accessory has a functional portion for cutting, sanding, or smoothing an object and an attachment portion that comprises a central opening with longitudinal and/or latitudinal openings extending radially from the central axis and a plurality of secondary openings. The secondary openings are also dispersed around the central axis. The accessory can fit, with no loss of functionality, oscillating power tools' connectors from multiple manufacturers.

A surgical system includes a surgical tool associated with a virtual haptic interaction point such that movement of the virtual haptic interaction point corresponds to movement of the surgical tool. The surgical system further includes a processing circuit to establish a virtual entry boundary and activate a haptic object, which constrains the surgical tool after the haptic interaction point crosses the virtual entry boundary.
