Abstract: A safety needle system operable with a medical device includes: a housing with a needle mount having a needle; and a sheath telescopically engaged with the housing and surrounding the needle such that the sheath operates in a retracted position, in which the sheath exposes the needle, and an extended position, in which the sheath surrounds the needle. The sheath is coupleable to the medical device such that removal of the needle from the medical device draws the sheath over the needle, transitioning the sheath from the retracted position to the extended position. In one embodiment, the system includes a slider engaged with the sheath and/or housing and including a restraint that engages and disengages the sheath to respectively reinforce and weaken the coupling of the sheath and medical device. In another embodiment, the sheath includes a longitudinal track that slidingly engages a setting of the housing between sheath positions.

Abstract: A surgical pump system arrangement receives an inflow cassette and provides fluid flow to a surgical site in a joint of a patient. The arrangement calculates load coefficients for a pressure loss curve based on an identified inflow cannula and an identified endoscope utilized therewith. The arrangement determines if the cannula is disposed at a surgical site and if adequate fluid flow is provided. Further, the arrangement determines if the inflow cannula and endoscope are properly identified. The arrangement integrates with an identified or unidentified surgical device to adjust pump operation when the surgical device is operating. The arrangement maps actuators disposed on a surgical handpiece or footswitch to control operation of the pump system, including providing suction to an outflow path of a surgical device that is not operating. The arrangement also determines when an inflow pump cassette is not properly inserted into the pump.
