A surgical fluid flow handpiece provides a range of relatively low flow rates with relatively fine manual control in selecting a flow rate in such relatively low range, and also provides for manual selection of a relatively high flow rate namely a flow rate well above such range. The handpiece is shaped to complement the shape of a users hand.

Various high-strength microwave antenna assemblies are described herein. The microwave antenna has a radiating portion connected by a feedline to a power generating source, e. g. , a generator. The antenna is a dipole antenna with the distal end of the radiating portion being tapered and terminating at a tip to allow for direct insertion into tissue. Antenna rigidity comes from placing distal and proximal radiating portions in a pre-stressed state, assembling them via threaded or overlapping joints, or fixedly attaching an inner conductor to the distal portion. The inner conductor is affixed to the distal portion by, e. g. , welding, brazing, soldering, or by adhesives. A junction member made from a hard dielectric material, e. g. , ceramic, can be placed between the two portions and can have uniform or non-uniform shapes to accommodate varying antenna designs. Electrical chokes may also be used to contain returning currents to the distal end of the antenna.

High-strength microwave antenna assemblies and methods of use are described herein. The microwave antenna has a radiating portion connected by a feedline to a power generating source, e. g. , a generator. The antenna is a dipole antenna with the distal end of the radiating portion being tapered and terminating at a tip to allow for direct insertion into tissue. The antenna can be used individually or in combination with multiple antennas to create a combined ablation field. When multiple antennas are used, microwave energy can be applied simultaneously to all the antennas or sequentially between the antennas. Furthermore, to facilitate positioning the antennas in or near the tissue to be treated, RF energy may be applied at the tip of the antenna to assist in cutting through the tissue.

A method of manufacturing a microwave antenna assembly includes the step of providing a proximal portion having an inner conductor and an outer conductor. Each of the inner and outer conductors extend through the proximal portion and the inner conductor is disposed within the outer conductor. The method also includes the step of placing a junction member adjacent to a distal end of the proximal portion such that the inner conductor extends through a channel defined in the junction member. The method also includes the step of placing a proximal end of a distal portion adjacent to a distal end of the junction member such that the inner conductor extends within a channel defined within the distal portion. The method also includes the step of affixing the inner conductor to the distal portion such that the proximal portion and the distal portion apply a compressive force on the junction member.
