Abstract: The present invention provides a disposable trumpet valve tube cassette assembly, as well as, a surgical irrigation instrument that includes a probe assembly, a pump, a removable pump cartridge, and a socket. The probe assembly provides passage of fluids for irrigating the body interior and for evacuating matter from the body interior. The pump provides for pumping irrigation fluid through the probe assembly into the body interior. A pump cartridge defines a pumping chamber. Electronic control circuitry includes an electronics controller and a trumpet valve switch interface. The electronics controller includes a pulse generator that generates pulses, the duty cycle of the pulses controlling the speed of the motor. The trumpet valve switch interface is in electronic connection to a switch, the interface providing a signal to the controller.

Abstract: The present invention provides a surgical device having a tissue engaging portion, a shaft member, and a handle assembly. The tissue engaging portion includes first and second opposed jaws for grasping, securing, and occluding body tissue and conduits. The shaft member is operatively coupled to the tissue engaging portion and is capable of being placed in different curvatures. The handle assembly is operatively coupled to both the shaft member and to the tissue engaging portion. The shaft member of the present invention allows the surgeon to bend and adjust the shape of the surgical device to minimize its intrusion and to allow for proper positioning in predetermined body locations. In a preferred embodiment, a portion of the device is disposable.

Abstract: A biopsy surgical appliance includes a stylet slider sliding in a longitudinal plane and placed laterally with respect to a longitudinal axis, a cannula slider sliding in a longitudinal plan placed laterally with respect to the axis of a needle and not interfering in the operative framework of stylet slider, holding/releasing device made up of a first independent hooking/releasing device for stylet slider, a second independent hooking/releasing device for cannula slider, two independent single control push-buttons of which the first one acts on the first hooking/releasing device and the second one is of the progressive type and acts in progression on said first hooking/releasing device at the first device if it has not been released yet and then on the second hooking/releasing device.
