Tissue pulsator operating with a tapping action, and method

A tissue pulsator capable of operating on an area to be treated with a tapping action, said pulsator including a head having on one side thereof a surface engageable with the area to be treated, said head comprising an enlarged, laterally facing pad having said surface on one side thereof, said surface being convex in all directions, and said pulsator including a rotary eccentric drive means connected to said head for laterally moving said surface thereof inwardly and outwardly substantially parallel to itself so as to operate on the area to be treated with a tapping action, said rotary eccentric drive means including:

• a. a housing providing a socket;
• b. a shaft having inner and outer ends and having intermediate its inner and outer ends a ball disposed in said socket;
• c. said head being connected to said outer end of said shaft;
• d. a crank connected to said inner end of said shaft;
• e. a rotary motor in said housing and substantially coaxial with said shaft and connected to said crank for rotating said crank substantially about the axis of said shaft so as to cause said outer end of said shaft to orbit, thereby laterally moving said surface of said head inwardly and outwardly substantially parallel to itself so as to operate on the area to be treated with a tapping action;
• and
• f. means interconnecting said shaft and said housing for preventing rotation of said shaft about its axis.
