Endoscopic device
First Claim
1. An endoscopic device for use in medical procedures comprising:
- a rigid hollow endoscopic tube having a distal end, a proximal end and a substantially cylindrical side wall, said distal end and said proximal end being open, and said endoscopic tube having an axis which is substantially straight, such that another endoscopic instrument having an external diameter smaller than the internal diameter of the endoscopic tube may be inserted therethrough while the distal end of the endoscopic tube is in a patient'"'"'s body;
at least a port formed in the endoscopic tube side wall near said distal endmeans for transferring vacuum from a vacuum source to the endoscopic tube, and thereby effectuating the removal of fluids and debris from said patient'"'"'s body while the endoscopic tube distal end is in said patient'"'"'s body; and
means for preventing the leakage of fluid or vacuum out of said proximal end.

Abstract
A multifunctional device for use in endoscopic medical procedures, capable of suction, irrigation and aqua-dissection, comprising an elongated tube that is open at both ends, a pair of valves in communication with the tube such that the device may be used for either suction, irrigation, or aqua-dissection, and further having an optional shield which may be attached for the suctioning of large volumes of fluid therethrough. A removable seal is attached to the proximal end of the tube, which seal can be replaced with an optional end cap for allowing the tube to be used to transmit other instruments into the operative field, which other instruments can be used simultaneously with the device while the device is performing suction or irrigation.
