Removable suction assembly for medical handpieces

摘要

A system and method for more efficient cleaning and sterilizing of surgical handpieces by using a removable valve assembly. The valve assembly is removable to provide access to a first suction passageway and a second suction passageway for cleaning purposes. The valve assembly has a protrusion that engages with a handpiece to secure the assembly to the handpiece. The protrusion of the valve assembly may also be retracted into the valve assembly to allow the valve assembly to disengage the handpiece thereby allowing the valve assembly to be removed from the handpiece. The first suction passageway may also be removable.

1. A surgical handpiece, comprising:
a first suction passageway; a second suction passageway; and a removable valve assembly for connecting or disconnecting the first suction passageway to the second suction passageway, the valve assembly comprising a protrusion for engaging the handpiece to secure the valve assembly to the handpiece, the valve assembly further comprising a spring that applies a force to the protrusion to disengage the protrusion from the handpiece, an action pin coupled to the protrusion and an action pin spring that interacts with the action pin, wherein the action pin extends perpendicular to the protrusion and applies a force to the protrusion to overcome the force of the spring and engage the protrusion with the handpiece, and wherein the action pin spring opposes movement of the action pin in a first direction.
