ABSTRACT:
An endoscopic surgical instrument for aspiration and irrigation of a surgical site. The device inclues at least one rotatable trumpet valve to provide for variable oreintation of the device during use. Connection ports for connection to irrigation fluid and a suction source are provided which communicate with a single lumen cannula which transports both the irrigation fluid and the suction pressure to the surgical site. The single lumen cannula is provided with a sleeve to vary the pressure of the irrigation fluid to provide for high pressure application of the irrigation fluid to perform hydrodissection. A plurality of dissector tips and a novel mechanism for securing the tips to the single lumen cannula are also dislcosed. Also disclosed is a novel dispensing device for the tips and a kit which includes the tip dispenser and an endoscopic surgical instrument.
