Microwave surgical instrument
It is an object to provide a surgical instrument capable of locally applying microwaves to a minute biological tissue. It has been found that microwaves can be transmitted to a tip of a tapered coaxial body (9) and that microwaves are radiated from the entire central conductor exposed in a major axis direction by decreasing a sectional area (preferably diameter) of a central conductor (1) and a sectional area (preferably inner diameter) of an external conductor gradually or in a step-by-step manner with a ratio between the sectional area (diameter) of the central conductor (1) and the sectional area (inner diameter) of the external conductor being set to be constant, thereby achieving the present invention..

Phase separation of cryogen in cryosurgical instrument
A cryosurgical instrument including: a shaft having a closed distal end defining an expansion chamber and an open proximal end that receives an inflow of cryogen and to exhaust a flow of expanded cryogen; and a heat exchanger with a cryogen delivery tube that spirals around a core disposed along longitudinal axis thereof. The cryogen delivery tube, at least where it spirals, is in fluid tight contact with the inner surface of the shaft so as to form spiraling cryogen exhaust pathways that extend along a portion of a length of the cryosurgical instrument from the distal end of the shaft.
