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.

Removable suction assembly for medical handpieces

A button for actuating a switch in a surgical handpiece. The button is sealed to a bezel, and the bezel is sealed to the handpiece. The button, bezel, and handpiece create a sealed enclosure surrounding the switch to prevent external substances from contacting the switch. Further, a control board for controlling the handpiece is embedded in a cable endcap instead of being housed within the handpiece.

Apparatus for sealing electronics from environment in DC powered arthroscopic surgical handpiece with pushbutton actuation

A system for enhanced sealing against intrusion of moisture and other contaminants for medical/dental handpieces having rotating or other moving elements driven by a motor within the handpiece. The enhanced sealing includes tandem seals on stepped diameters to provide additional flow pathway impediments. The tandem seals preferably include spring seals that are positioned in opposite directions to provide enhanced sealing against pressures in two different directions that occur during the pressurization and vacuum cycles of an autoclaving process. Additional enhancements include the use of annular sealing rings with x-shaped cross sections.
