A medical manipulator having: a first rotatable body configured to be rotated about a rotation axis to exert a driving force transmitted by a wire to drive at least one of an elongated portion and an end effector; and a second rotatable body configured to be detachably coupled to the first rotatable body, wherein the second rotatable body is operatively connected to an actuator to be rotated by the actuator, wherein a shape of the first rotatable body corresponds to a shape of the second rotatable body such that as the first rotatable body and the second rotatable body are brought into contact with each other, a pressing force with which the first rotatable body is pressed against the second rotatable body is converted into a rotational force of the second rotatable body to rotate the second rotatable body into a predetermined alignment with the first rotatable body.

Medical manipulator

A medical manipulator system includes a manipulator having a first joint; a first detecting means detecting an orientation of the first joint; an operation unit having a second joint associated with the first joint for operating the first joint; a second detecting means detecting an orientation of the second joint; a control unit outputting a signal for operating the first joint, the signal being based on the orientation of the second joint detected by the second detecting means; and a display unit displaying information output by the control unit, wherein a display of the information by the display unit includes a first display indicating a predetermined range of an orientation determined by using the orientation of the first joint that is detected by the first detecting means as a reference and a second display indicating the orientation of the second joint that is detected by the second detecting means.

Medical manipulator system

A method for controlling a manipulator includes a joint structure portion having one or more joints connected to a distal end of an insertion portion, a power transmission member inserted into the insertion portion to transmit driving force to the joint structure portion, and a driving portion that drives the power transmission member and which is guided to an application site by being inserted into the channel member. When the manipulator is operated in an insertion control mode for inserting the joint structure portion into the channel member, the method includes detecting a load amount generated in the power transmission member or the driving portion; and creating a bending state in which the joint structure portion follows the channel member by controlling a driving amount of the power transmission member by the driving portion such that the load amount becomes within a predetermined target control range.

Manipulator control method, manipulator, and manipulator system

The endoscope treatment system includes an endoscope treatment tool that has an operating part having a distal end and a proximal end, and a sheath that is connected to the distal end of the operating part and is formed with a lumen through that enables a guide wire to be inserted therethrough; a guide wire holder around which a tube member housing the guide wire is wound circumferentially; and a fixing member that couples the operating part to the guide wire holder such that the distal end and the proximal end of the operating part are located outside the circumference of the guide wire holder.
