A microwave ablation probe tip comprising:
- a post portion configured to be received in an ablation probe needle, the post portion comprising:
- a cylindrical body defining:
- one or more annular grooves disposed circumferentially on an outer surface of the cylindrical body;
- and
- a center bore extending through the cylindrical body;
- a tube positioned in the center bore;
- an insertion portion connected to the post portion, the insertion portion comprising:
- an insertion portion body tapering to terminate at a point;
- and
- a shoulder at which the insertion portion is connected to the post portion, wherein the insertion portion body tapers in a direction away from the shoulder, wherein the tube extends away from the center bore in a direction away from the insertion portion;
- and
- a ferrule, wherein at least a portion of the ferrule is received inside the center bore and the tube shields a portion of the ferrule.
