手术器械
摘要：
本发明涉及一种手术器械。一种手术抹刀，具有平面传输线（10），该平面传输线用于承载从相对的面上具有第一导电层（14）和第二导电层（16）的第一电介质材料片（12）形成的微波能量。该手术抹刀还具有用于将微波能量递送到平面传输线（10）的同轴线缆（20）。该同轴线缆具有内导体（22）、与内导体（22）同轴的外导体（24）、以及分隔内导体（22）和外导体（24）的第二电介质材料（26）。内导体（22）和外导体（24）延伸超出第二电介质（26），以与传输线（10）的相对的表面交叠并且分别与第一导电层（14）和第二导电层（16）电接触。第一导电层（14）的和第二导电层（16）的宽度被选择成在传输线（10）和同轴线缆（20）之间建立阻抗匹配。
摘要（英）：

The invention relates to a surgical instrument. A surgical spatula has a planar transmission line (10) for carrying microwave energy formed from a sheet of a first dielectric material (12) which has first (14) and second (16) conductive layers on opposite sides thereof. The surgical spatula also has a coaxial cable (20) for delivering microwave energy to the planar transmission line (10). The coaxial cable has an inner conductor (22), an outer conductor (24) coaxial with the inner conductor (22) and a second dielectric material (26) separating the inner (22) and outer (24) conductors. The inner (22) and outer (24) conductors extend beyond the second dielectric (26) to overlap opposite surfaces of the transmission line (10) and electrically contact the first (14) conductive layer and second (16) conductive layer respectively. The width of the first (14) and second (16) conductive layers is selected to create an impedance match between the transmission line (10) and the coaxial cable (20).
