Title:
SURGICAL TOOL
Document Type and Number:
WIPO Patent Application WO/2018/193493
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a surgical tool that is capable of remedying variation in the temperature of a blade part. This surgical tool (11) is provided with: a blade part (25) that has a treatment surface (61) that comes into contact with biological tissue; a heater (27) that has a heating surface (53) that extends in a direction that intersects with the treatment surface (61); and a thermal conduction member (26) that is interposed between the heating surface (53) and the blade part (25) so as to thermally contact the heating surface (53) and the blade part (25), and exhibits anisotropy in thermal conductivity such that thermal conductivity increases in the longitudinal direction of the blade part (25) and thermal conductivity decreases in the width direction of the blade part (25) that intersects with the longitudinal direction.
