ABSTRACT:
A composite suction and irrigation probe is provided for performing the functions of irrigation and suction alone or simultaneously with the use of a single trumpet valve. The probe consist of an inner cannula and an outer cannula. In the first embodiment the inner cannula is attached to one probe mount end of the valve body while the outer cannula is attached to a second and opposite probe mount end. The inner cannula is inserted through a common channel of the valve body and the outer cannula. In the second embodiment, the inner cannula is attached to the outer cannula prior to attaching the probe to the valve body. The designated suction and irrigation ports located within the common channel of the valve body are isolated from each other to provide discrete and dedicated ports.
