摘要:
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.

A medical apparatus includes a first jaw; a second jaw that opens and closes with the first jaw; a shaft to which the second jaw is pivotably attached; and a sliding member provided between the second jaw and the shaft, abutted to each of the second jaw and the shaft, and configured to be slidable with respect to at least one of the second jaw or the shaft.

A treatment instrument includes a rotating body and a housing. The rotating body includes a connecting portion including: a supported portion having a cylindrical outer peripheral surface, and an engaged portion that is adjacent to the supported surface. The housing includes a supporting portion that is configured to support the supported portion of the rotating body, the supporting portion being rotatable around a predetermined rotation axis; and an engaging portion that is configured to generate a frictional force larger than a frictional force between the supporting portion and the supported portion by coming into contact with the engaged portion.
摘要:
In a treatment instrument, one of a pair of jaws is supported by a supporter while being pivot able around the supporter with respect to the supporter. A drive member moves along a longitudinal axis so that the pair of the jaws are closed with respect to each other, thereby applying an axial force onto an elongated member from the drive member by way of the one of the jaws and the supporter in a direction along the longitudinal axis. A contact surface of the elongated member abuts on a housing when the elongated member moves with respect to the housing under the axial force, thereby suppressing rotation of the elongated member around the longitudinal axis with respect to the housing.

An image processing apparatus including: an image acquisition device for observing a living body; a blood vessel recognition device that irradiates the living body with an exploration laser beam and that recognizes a blood vessel; an arithmetic operation unit that calculates a first laser spot position on a first frame acquired by the image acquisition device when the blood vessel is recognized and that adds a mark corresponding to the first laser spot to a position on a second frame corresponding to the first frame, the second frame being acquired at a time different from the time of the first frame; and a display unit for displaying, on an image acquired by the image acquisition device, a plurality of the marks added by the arithmetic operation unit as a result of the blood vessel being recognized at a plurality of different times.

A medical instrument includes: a jaw which is provided with a grasping section; and a blade which is movable close to and away from the grasping section and which extends from a distal-end portion thereof to a proximal-end portion thereof, the blade having a top portion including a ridge opposed to the grasping section, and the ridge of the top portion in the proximal-end portion being sharper than the ridge of the top portion in the distal-end portion.
摘要:
In a blade of a grasping treatment unit, a top sharpening toward a jaw forms a ridge line along a longitudinal direction of the blade, and in the jaw, a grasping surface opposed to the top extends. A proximal side counter portion, on which the top can abut while the blade and the jaw are closed relative to each other, is provided in a region of the grasping surface located on a proximal side with respect to a distal portion, and a distal side counter portion, which does not contact the top while the top abuts on the proximal side counter portion, is provided in the distal portion of the grasping surface.
摘要:
A treatment instrument includes a treatment body that includes a treatment surface provided in the first clamp surface, the treatment surface protruding toward the second clamp surface in response to the supply of heat energy and increasing pressure on the living tissue to treat the living tissue in cooperation with the action of the heat energy.
摘要:
A grasping treatment unit includes a first jaw, and a second jaw openable and closable relative to the first jaw. In the first jaw, a heating wire continues without branching from a first extending end to a second extending end, and heat is generated over an entire length from the first extending end to the second extending end when the electric current flows through the heating wire. In a heating portion, a calorific value per unit area is higher in a distal portion than in a proximal portion in the first jaw when the heat is generated from the heating wire. On a treatment surface of the first jaw, an amount of heat transfer from the heating portion is greater in the distal portion than in the proximal portion.
摘要:
An electrically conductive plate of a treatment instrument includes a treating surface and a back surface facing an opposite side of the treating surface, and an electric component is arranged on the back surface of the electrically conductive plate. The electric component is electrically independent from the electrically conductive plate, and a holder supports the electrically conductive plate from the back surface side. A connector is made of a thermoplastic resin, and arranged on either side of and spaced from the electric component in a width direction intersecting with a longitudinal axis. The connector stationarily fixes each end of the electrically conductive plate in the width direction to the holder.
