Abstract: An actuating means (107) for a self-adjusting pump head assembly (101), including a variable position pump shoe (102) slideably attached to a base (103), wherein the assembly (101) is used to pump liquides through a tube (104) introduced into a peristaltic pump, including (a) means (107) for translating rotational motion into linear motion, and (b) cranking means (107), including means (107) for automatically compensating for the manufacturing tolerances of a tube (104) introduced into the pump, pivotally attached to both the means (107) for translating and the shoe. The means (107) for automatically compensating preferably includes a pair of links, carrying a helical compression spring (328), pivotally anchored to both the means (107) for translating and the shoe. A peristaltic pump is also described. The pump includes (a) a self-adjusting pump head, including a variable position pump shoe (102) slideably attached to a base (103); and (b) a control for positioning, locking and applying a continuous reaction force on the shoe to compress the tube (104) between the shoe and at least one roller located on the periphery of a mandrel (150), wherein the control further comprises means (107) for translating rotational motion into linear motion, and cranking means (107), including means (107) for automatically compensating for the manufacturing tolerances of a tube (104) introduced into the pump, pivotally attached to both the means (107) for translating and the shoe. The pump may be alternatively characterized as including a disposable manifold (400) safety cartridge (505), removably attached to the base (103), to which the ends of the tube (104) are attached; with the cartridge (505) being formed to include an asymmetrical tie bar (412) that is keyed onto the base (103) to ensure that the cartridge (505) is oriented in an acceptable manner and that the tube (104) introduced into the pump will be properly installed.

Abstract: An ultrasonic surgical aspirator having an improved irrigation/aspiration manifold and components to facilitate quick connections of the irrigation and aspiration lines to a handpiece. In combination with a handle assembly (31) having an ultrasonic vibrator (32) for vibrating an ultrasonic tip (34) and a nosecone (33), a nosecone extension (42) defining a rotating joint (43) for connection to the nosecone in an articulating joint for connection to a rigid or flexible flue (47, 49). The nosecone extension further defines an irrigation cowl (77) having an irrigation port for receiving an irrigation connector (77) for connecting the irrigation fluid to the nosecone extension for passage of irrigation fluid through the nosecone extension and a flue about the surgical tip. An aspiration tubulation connector (71) adapted to securely fit a slot through the nosecone and nosecone extension connects an aspiration port (37) on the tip to the aspiration tube (76) for connection to a pump into a discard.
