A manipulator includes an elongated portion; a bending portion coupled to a distal end of the elongated portion, the bending portion being formed by articulating a plurality of segment pieces; an end effector coupled to a distal end of the bending portion; an actuator coupled to a proximal end of the elongated portion; a first wire coupled to between the actuator and the end effector, the first wire being configured to actuate the end effector; and a second wire coupled to between the actuator and the bending portion, the second wire being configured to actuate the bending portion. Each of the plurality of segment pieces is configured to be articulated so as to be twisted with respect to a longitudinal central axis of the bending portion, and the first wire is configured to be inserted into the plurality of segment pieces so as to form a substantially twisted path.

Manipulator

A manipulator is used to operate a surgical device that treats a body tissue. The manipulator includes a drive mechanism having a stationary section to be attached on a housing of a drive unit containing with at least one motor. A movable part is supported rotatably about a predetermined axis on the stationary section and having a connecting portion configured to be connected to the at least one motor when the stationary section is attached on the housing. A cover is configured to seal a gap between the movable part and the stationary section so as to prevent fluid from entering the gap between the movable part and the stationary part. A power transmission member is connected to both the movable part and the surgical device to transmit power from the motor to the surgical device.

Manipulator for driving surgical device that treats body tissue

When taking in outside air with a fan to control the temperature inside a covered portion where a specimen is installed, the internal temperature may change depending on an environment temperature to cause a difference in temperature control. The wind generated by the fan may blow against a reaction container depending on its loading position and it may influence the temperature control over individual specimens and lead to problems with temperature accuracy, temperature rise speed, and temperature drop speed. A reaction container avoiding these problems has a covered portion which performs temperature control on the reaction container and in which a cover and a fin cover have a heat insulating structure. A heat source is provided for controlling an internal temperature of an internal covered space. The internal temperature is kept constant and the influence of the environment temperature over the temperature control of the reaction container is minimized.
