POWERED SURGICAL TOOL WITH A CONTROL MODULE IN A SEALED HOUSING THE HOUSING HAVING ACTIVE SEALS FOR PROTECTING INTERNAL COMPONENTS FROM THE EFFECTS OF STERILIZATION
A powered surgical tool with a housing that contains a power generating unit such as a motor. A control module is disposed in a shell that is mounted in the housing. Conductive pins extend through the shell to provide electrical connections to the components within the shell. An active seals are disposed around the conductors and the inner walls of the shell that define the openings in which the shells are seated. Each active seal include an inner and outer skirt. A biasing component disposed between the skirts urges the inner skirt against the section of the conductive pin seated in the opening. The biasing component also urges the outer skirt against the adjacent opening-defining inner wall of the shell. The active seal functions as a barrier between the conductive pin and the adjacent inner wall of the shell.
