ABSTRACT:
An endoscopic surgical instrument for aspiration and irrigation of a surgical site. The device includes at least one rotatable trumpet valve to provide for variable orientation of the device during use. Connection ports for irrigation fluid and a suction means 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 means 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 means of securing the tips to the single lumen cannula are also disclosed.
