摘要： A medical treatment tool includes a tubular sheath having a longitudinal axis, a treatment section supported by a distal end of the sheath in a rotatable manner around the longitudinal axis, an operating section connected to a proximal end of the sheath, and a transmission mechanism that transmits an operational amount applied to the operating section so as to rotate the treatment section around the longitudinal axis. The transmission mechanism includes two transmitting sections that transmit different rotational amounts to the treatment section in accordance with two different kinds of operations performed on the operating section. At least one of the transmitting sections converts an operational amount applied to the operating section along a direction of the longitudinal axis into a rotational amount around the longitudinal axis between the operating section and the treatment section and transmits the rotational amount to the treatment section.

摘要： A medical system includes a treatment tool provided with an end effector that treats a tissue, an imager capturing an image of the tissue, and a processor. The processor acquires color information of a target tissue from the captured image output from the imager. The target tissue is a portion of the tissue that covers at least a portion of the end effector that has slid into the tissue. The processor estimates a force applied to the target tissue by the end effector from the color information of the target tissue. The processor notifies an operator of a result of the estimation of the force.

摘要： A medical treatment tool of the present invention includes a supporting unit; a pair of grasping pieces, at least one of which is supported on the supporting unit so that the at least one grasping piece pivots on a pivot axis orthogonal to a longitudinal axis of the supporting unit; and a driving mechanism causes the grasping piece to pivot. The driving mechanism includes a cylindrical part disposed at a proximal end of the grasping piece and having the pivot axis; a driving member having an outer surface that makes rolling contact with an inner surface of the cylindrical part, the driving member being rotatably supported on an inner side of the cylindrical part so that the driving member rotates about an axis parallel to the pivot axis; and a force transmitting member transmitting a force applied to a proximal end of the supporting unit to rotate the driving member.

摘要： A treatment tool includes an long member; a treatment portion rotatable about a longitudinal axis of the long member; a twisting wire one end of which is connected to the treatment portion, the other end extending toward a proximal end side of the long member; an operating portion, at the proximal end side, that includes a body fixed to the long member, and an operating member configured to rotate around and move along the axis; and a mechanism configured to couple the operating member with the wire and convert a rotation of the operating member into traction of the wire. The body includes a portion configured to come into contact with the operating member to prevent the rotation in a case where the operating member is urged in a direction toward a distal end side of the long member together with the mechanism by a restoring force of the wire.

摘要： A medical-manipulator rotation mechanism includes: a cylindrical rotator that is fixed to a treatment part at the distal end and that is supported so as to be rotatable about the longitudinal axis; a long power-transmitting member wound around the rotator; and a folding part that bends the power-transmitting member led out in a tangential direction from the rotator and guides the power-transmitting member toward the proximal-end side, wherein the power-transmitting member is led out in tangential directions at different positions between which a wound part of the rotator around which the power-transmitting member is wound exists.

摘要： The system includes a memory that stores a trained model, and a processor. The processor acquires a pre-treatment image in which at least one energy device and at least one biological tissue are imaged, and a state before application of energy is imaged. The processor estimates an estimated heat diffusion region from the pre-treatment image and information regarding an energy supply amount by processing based on a trained model stored in the memory. The processor superimposes the estimated heat diffusion region on a captured image of the camera and displays the captured image with the superimposed estimated heat diffusion region.
