A percussive therapy device that includes a housing, an electrical source, a motor positioned in the housing, a switch for activating the motor, a push rod assembly operatively connected to the motor and configured to provide reciprocating motion in response to activation of the motor, and a massage attachment secured to a distal end of the push rod assembly. The reciprocating motion of the push rod assembly has a user-adjustable amplitude.

A percussive massage device that includes a housing, an electrical source, a motor positioned in the housing, a switch for activating the motor, and a push rod assembly operatively connected to the motor and configured to reciprocate in response to activation of the motor. The housing includes first, second and third handle portions that cooperate to define a handle opening, wherein the first handle portion defines a first axis, the second handle portion defines a second axis and the third handle portion defines a third axis, and wherein the first, second and third axes cooperate to form a triangle.

A reciprocating saw blade includes a body defining a longitudinal axis. The blade includes a cutting portion having a plurality of cutting teeth. Each cutting tooth includes a protrusion and a tip spaced a first distance from the protrusion. The tip of a first cutting tooth is spaced a pitch distance from the tip of an adjacent second cutting tooth. A gullet is defined between the tip of the first cutting tooth and the protrusion of the adjacent second cutting tooth. The tip of a respective cutting tooth is spaced a tip height distance from a base of the gullet. An apex of the protrusion is spaced a protrusion height distance from the base of the gullet. The protrusion height distance is 65% to 68% of the tip height distance. The first distance is 40% to 77% of the pitch distance.

A hole saw includes a base member configured to secure the hole saw to a drive device and a plurality of blade members extending orthogonally to the base member. The blade members are configured to cut into a structure to form a polygonal opening in the structure in response to rotational movement of the hole saw by the drive device. Each blade member is attached to the base member in a fixed position relative to the base member and has cutting teeth extending in a respective cutting direction. First and second blade members of the plurality are disposed parallel to each other and have I-shaped faces that face each other. Third and fourth blade members of the plurality are disposed parallel to each other and have I-shaped faces that face each other.

A saw blade includes a blade body having a top surface and a bottom surface, wherein the blade body is at least partially comprised of a first composite material or a metal; a cutting edge on a distal end of the blade body; and a coupling configured to connect the blade body to a handpiece adapted to oscillate the blade body. The saw blade may include: a first inlay portion and a second inlay portion, where the first inlay portion is either embedded in the top surface or covers the top surface, and the second inlay portion is either embedded in the top surface or covers the bottom surface; or an inlay portion sandwiched between a top portion and a bottom portion of the blade body.

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.

A surgical saw blade including a cutting edge, blade body and a coupling for connecting the blade body to a handpiece. The blade body at least partially includes a composite material that helps to confer optimal weight and rigidity to the saw blade to allow for minimal vibration during use and minimal mechanical load on the handpiece.

A saw gear set comprising a set of saw blades and a saw drive (1), wherein each saw blade of the set is configured to be coupled to the saw drive (1) by means of a coupling mechanism (100), which coupling mechanism (100) is configured to transmit a driving force of the saw drive (1) to the saw blade in a force transmission point, for oscillating the saw blade around a pivot axis (300). Each saw blade of the set is configured to be pivotably borne around the pivot axis (300). In operation, an oscillation angle (α) around the pivot axis (300) is different for each saw blade of the set depending on a pivot distance between the pivot axis (300) and the force transmission point which varies for each saw blade of the set.

A reciprocating saw includes a blade assembly having a spindle and a blade clamp. The blade clamp includes a cover rotatably coupled to the spindle, and a detent movable in a radial direction to adjust the blade clamp between a locked configuration and an unlocked configuration. The cover is rotatable between a first rotational position relative to the spindle coinciding with the locked configuration, and a second rotational position relative to the spindle coinciding with the unlocked configuration. The reciprocating saw further includes a barrel surrounding at least a portion of the blade clamp. The barrel includes a plurality of projections extending from the barrel toward the blade clamp. At least one of the projections is engageable with the cover to rotate the cover from the second rotational position to the first rotational position, thereby adjusting the blade clamp from the unlocked configuration toward the locked configuration.
