Abstract: An ultrasonic and electrosurgical handpiece housing has an axis, a distal end, a proximal end and a passage defined by an inside wall. A piezo stack has elements carried along a plane generally transverse to the axis. A retainer for the elements has distal, intermediate and proximal portions. The distal portion has a fastener; the proximal portion has a threaded shoulder bolt. The stack about the shoulder has an energy input and a reference output positioned axially apart from one another. An insulating sleeve about the bolt is between central openings of the elements and the bolt. A pair of insulators about the bolt has the stack therebetween; one insulator is between the plane and the stack and the other is near the threads. The intermediate portion attaches to the housing at the plane with decoupling and sealing. An irrigation channel conveys fluid. The drive energy input, the feedback signal and the reference outputs are insulated by the sleeve and pair from the bolt. A washer against the insulator and about the threads applies axial but not torsion to the insulator when a clamping nut on the threads holds components on the bolt. The clamping nut is in circuit with electrosurgical energy as the reference return for electrosurgery. A tool fastens to a connector for transmitting axial vibrations in the form of a predefined stroke at a tip thereof.

Abstract: A connection of first and second members wherein each has a body and a connecting end with an inner surface so the second connecting end has an outer surface shaped for telescoping into the inner surface of the first connecting end. A shoulder is located on the second member and a groove is in the outer surface of the second connecting end. A raised nub on the inner surface of the first connecting end is radially inward to engage the groove. An elastomeric gasket is positioned to bear against the shoulder and be compressed between the first and second bodies. An engaging trough in the groove holds the first connecting end against the shoulder with the nub against the groove by the compression force of the gasket. An indexing trough in the groove positioned along the groove beyond the engaging trough allows the nub to follow therethrough and slightly compress the gasket thus giving the user a tactile indication that it has been rotated beyond the engaging trough. A method for fluid tight attachment of members of a medical device has steps including providing the connection of the first and second members with ends by telescoping the ends. Locating a groove for operating the groove as a cam and locating a raised nub of material on the inner surface of the first connecting end for positioning the raised nub to engage the groove for operating the raised nub as a follower of the cam are steps. Compressing a gasket seal between the first connecting end and the shoulder while making the gasket seal from an elastomeric material is a step. Positioning an engaging trough in the groove to hold the first and second connecting ends against each other is a step. Positioning an indexing trough in the groove so when the nub is rotatably forced past the engaging trough it will further compress the first end against the gasket is a step.
