Abstract: A connection of first and second members (11 and 12) wherein each has a body and a connecting end with an inner surface (17) so the second connecting end (19) has an outer surface (20) shaped for telescoping into the inner surface (17) of the first connecting end (16). A shoulder (21) is located on the second member (12) and a groove (22) is in the outer surface (20) of the second connecting end (19). A raised nub (23) on the inner surface (17) of the first connecting end (16) is radially inward to engage the groove (22). An elastomeric gasket (13) is positioned to bear against the shoulder (21) and be compressed between the first and second bodies. An engaging trough (24) in the groove (22) holds the first connecting end (16) against the shoulder (21) with the nub against the groove (22) by the compression force of the gasket (13). An indexing trough (25) in the groove (22) positioned along the groove (22) beyond the engaging trough (24) allows the nub to follow therethrough and slightly compress the gasket (13) thus giving the user a tactile indication that it has been rotated beyond the engaging trough (24). A method for fluid tight attachment of members (11 and 12) of a medical device has steps including the connection of the first and second members (11 and 12) with ends by telescoping the ends. Locating a groove (22) for operating the groove (22) as a cam (14) and locating a raised nub (23) of material on the inner surface (17) of the first connecting end (16) for positioning the raised nub (23) to engage the groove (22) for operating the raised nub (23) as a follower of the cam (14) are steps. Compressing a gasket (13) seal between the first connecting end (16) and the shoulder (21) while making the gasket (13) seal from an elastomeric material is a step. Positioning an engaging trough (24) in the groove (22) to hold the first and second connecting ends (19) against each other is a step. Positioning an indexing trough (25) in the groove (22) so when the nub is rotatably forced past the engaging trough (24) it will further compress the first end against the gasket (13) is a step.

Abstract: An ultrasonic surgical handpiece (10) for surgery on a patient has a handpiece with distal and proximal ends (12) on a housing (13) thereof for manipulation by a surgeon. A vibrator (19) is carried within a hollow (15) inside of the housing (13). A tool (16) extends from the vibrator (19) at the distal end (21) to the distal tip (22) and is tubular with a bore (17) along its axis so axial vibrations at high frequency are transmitted to the distal tip (22). Fluid (27) flows from the distal tip (22) to the vibrator (19), cools the vibrator (19) and connects to a source of suction (24) at the proximal end (12). A flue (25) carried cantilever on the distal end (21) extends about the tool (16) so a space is between the tool (16) and the flue (25) for guiding fluid (27) from the distal end (21) to the distal tip (22). A port located through the tool (16) connects between the space and the bore (17) and is axially positioned near the distal end (21) to collect fluid (27). An inlet (26) on the flue (25) is near the distal end (21) for fluid (27) provided by a supply. The inlet (26) is axial distal of the port and/or may meter fluid (27) to a preset range. The port may be at, near or toward a low stress region of the tool (16). The vibrator (19) is piezo. The port can be diametrically opposed to the inlet (26). Holes (29) may be located through the tool (16) near the distal tip (22) to prevent misting, clogging or dripping of fluid (27). A method of cooling the ultrasonic surgical handpiece (10) has steps that circulate fluid (27) from the inlet (26) to the space and port and pass cooling fluid (27) about the vibrator (19) and to the source of suction (24). A method of making the ultrasonic tool (16) may include having one or more ports (30) through the tool (16) to the bore (17) wherein the ports (30) are at, near or toward low stress regions and allow fluid (27) flow from the space to the bore (17).

Abstract: An ultrasonic and electrosurgical handpiece (10) housing (11) has an axis, a distal end (12), a proximal end (13) and a passage (14) defined by an inside wall (40). A piezo stack (26) has elements (16) carried along a plane (17) generally transverse to the axis. A retainer (18) for the elements (16) has distal, intermediate and proximal portions (21). The distal portion (19) has a fastener (22); the proximal portion (21) has a threaded shoulder bolt (24). The stack (26) about the shoulder has an energy input (29) and a reference output (30) positioned axially apart from one another. An insulating sleeve (31) about the bolt is between central openings of the elements (16) and the bolt. A pair of insulators (32) about the bolt has the stack (26) therebetween; one insulator (32) is between the plane (17) and the stack (26) and the other is near the threads. The intermediate portion (20) attaches to the housing (11) at the plane (17) with decoupling and sealing. An irrigation channel (44) conveys fluid. The drive energy input (29), the feedback signal and the reference outputs (30) are insulated by the sleeve (31) and pair from the bolt. A washer (34) against the insulator (32) and about the threads applies axial but not torsion to the insulator (32) when a clamping nut (35) on the threads holds components on the bolt. The clamping nut (35) is in circuit with electrosurgical energy as the reference return for electrosurgery. A tool (36) fastens to a connector (37) for transmitting axial vibrations in the form of a predefined stroke at a tip (38) thereof.
