An irrigation system for a surgical instrument includes an irrigation tube arranged to convey an irrigation fluid and an irrigation clip structurally arranged to receive a portion of the irrigation tube. The irrigation clip includes a proximal portion, a distal portion, a body portion, and an arm portion. The arm portion is structurally configured to selectively attach the irrigation clip to the surgical instrument and to bias the irrigation clip toward the surgical instrument with a biasing force. The irrigation clip includes a tube locking portion structurally arranged to cooperate with the surgical instrument to engage the outer surface portion of the irrigation tube to inhibit rotation and axial displacement of the irrigation tube relative to the irrigation clip in response to the biasing force.

Irrigation system and clip for a surgical instrument

A surgical cutting tool adapted to be rotatably driven by a motor. The surgical cutting tool includes an elongated shaft defining intermediate and coupling portions. A shape of the intermediate portion defines a primary central axis of the shaft. The coupling portion includes a tang having a tapered cylindrical shape that defines a drive axis. The drive axis is slanted with respect to the primary central axis. When coupled to the motor of a powered handpiece, the tang transmits an input or drive force from the motor to the intermediate portion as a torque about the primary central axis. In some embodiments, the drive axis extends through a centroid of first and second spaced apart cross-sectional planes of the tang, the first and second planes each being perpendicular to the primary central axis.

A surgical cutting blade for cutting bone material when the blade is coupled to a hand-held surgical saw includes a distal portion comprising a plurality of cutting teeth, a shank portion adjacent the distal portion, and a proximal portion adjacent the shank portion. The proximal portion may include a longitudinally extending slot having a proximal opening. The slot may be shaped to receive a portion of the surgical saw through the proximal opening. The proximal portion may have a plurality of deflectable fingers respectively separated from a plurality of main body portions by respective gaps. The plurality of deflectable fingers may extend adjacent the longitudinally extending slot, and may deflect into the gaps to increase and decrease a width of a portion of the slot.

A surgical system for cutting tissue of a patient includes an outer housing and a reciprocating assembly structurally configured to carry a cutting tool in a reciprocating motion. An actuator knob is manually accessible to the user and may be fixed axially to the outer housing. The reciprocating assembly may reciprocate relative to the actuator knob. The actuator knob may be configured for rotational movement between a lock position and an unlock position. The system may also include a locking mechanism configured to retain a cutting tool within the reciprocating assembly. The locking mechanism may be responsive to movement of the actuator knob to maintain the tool within the output shaft when the actuator knob is in the lock position and permit removal of the tool when the actuator knob is in the unlock position. Surgical cutting tools, such as blades include thickness enhancing features.

Saw blade stability and collet system mechanism

A cartridge includes a body, a reservoir, a filter, and a tab. The body is configured to be held in a fixed relationship relative to a stem, wherein the body comprises an inlet and an outlet. The inlet is configured to receive a fluid from a surgical instrument via the stem. The outlet is configured to output a first portion of the fluid from the cartridge. The reservoir is configured to receive the fluid from the inlet. The filter is configured to filter the first portion of the fluid as the first portion of the fluid is directed from the inlet, through the filter, and to the outlet. The tab connected to the body and configured to engage with the stem. The tab is configured to, when the cartridge is moved to disengage from the stem, at least one of break away from the body and become functionally inoperable.

Lubrication and exhaust system for a powered surgical instrument

A lubrication cartridge includes a cartridge body. A cartridge coupling is located on the cartridge body and defines a first passage and a second passage. A lubricant reservoir is housed in the cartridge body and comprises a pressurized fluid inlet coupled to the first passage and a lubricant outlet coupled to the second passage. A metering insert is located between the lubricant outlet and the second passage and comprises a density that controls lubricant flow between the lubricant reservoir and the second passage.
