Cool-tip thermocouple including two-piece hub
First Claim
1. A surgical device for performing a surgical procedure, the surgical device comprising:
- a handle assembly including a housing having a distal end and a proximal end;
a tissue engaging member supported in and extending from the distal end of the housing of the handle assembly;
at least one conduit having a first end operatively associated with the tissue engaging member and a second end extending from the housing of the handle assembly;
an inner tube disposed at least partially within an outer tube, the inner tube operatively associated with a thermocouple assembly, the thermocouple assembly including a first thermocouple extending through the inner tube and a second thermocouple, the first thermocouple electrically connected to the inner tube, and disposed between an inflow lumen and the inner tube, whereas a first end of the second thermocouple is electrically connected to a thermocouple measuring circuit and a second end of the second thermocouple is connected to the inner tube, the inner tube and the inflow lumen fluidly connected to the at least one conduit; and
a strain relief member supported on the at least one conduit and connected to the housing, wherein the strain relief member and the housing are configured to enable poly-axial movement of the strain relief member with respect to the housing,wherein an annular rib is positioned on the strain relief member and is configured to extend within a portion of the housing to facilitate connection of the strain relief member to the housing.
