Abstract
A heating blade unit, a treatment tool, and a method of manufacturing a heating blade unit are disclosed. The heating blade unit includes: an electric heater, a blade, and a cover made of a thermosetting resin. The blade includes a treatment surface, an installation surface that is provided on a side opposite to the treatment surface and on which the electric heater is installed, and a support surface that is provided at a position different from a position at which the installation surface is provided. The cover integrally covers the electric heater, and one or more surfaces of the blade.
Claims19
A treatment tool comprising:
- an electric heater,
- a blade including:
- a treatment surface configured to perform treatment on a biological tissue,
- an installation surface provided on a side opposite to the treatment surface, the electric heater installed on the installation surface, and
- a flange protruding outward from a lateral side of the blade in a width direction transverse to the stacking direction of the blade and the electric heater, the flange including a support surface provided at a different position from the installation surface in a stacking direction of the blade and the electric heater, the support surface being opposite to the treatment surface,
- a resin cover covering the electric heater, the installation surface, and at least a part of the support surface;
- and
- a holder holding the blade and the resin cover, the holder directly contacting both the resin cover and the blade.
