IMPROVED COMPOSITE IRRIGATION AND SUCTION PROBE

摘要

A composite suction and irrigation probe (130) is provided for performing the functions of irrigation and suction alone or simultaneously with the use of a single trumpet valve (112). In the first embodiment (figures 6 and 8) 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 cannula. In the second embodiment, the inner cannula (162) is attached to the outer cannula (160) prior to attaching to the probe (130) to the valve body (112). The designated suction and irrigation ports (138 and 139) located within the common channel (186) of the valve body are isolated from each other to provide discrete and dedicated ports.
