the operation unit includes a pair of the enable switches provided on opposite sides of the outer peripheral surface of the operation unit; and
at least one enable switch of the pair of enable switches is configured to allow the movement of the arm when the operator grasps the outer peripheral surface of the operation unit and presses the at least one enable switch of the pair of enable switches.
5. The surgical robot according to claim 4 , wherein
the operation unit has a cross-section having a substantially rectangular shape; and
the pair of enable switches are provided on side surfaces of the operation unit that face each other, respectively.
6. The surgical robot according to claim 1 , wherein the joystick is arranged at a position on the end face operable by a finger of the operator while the operator grasps an outer peripheral surface of the operation unit and presses the enable switch.
7. The surgical robot according to claim 1 , wherein
the arm includes an arm portion including an articulated robot arm, and a translation mechanism provided at a tip end of the arm portion, the translation mechanism being configured to allow a medical device to be attached thereto, the translation mechanism being configured to translate the medical device relative to the arm portion; and
the operation unit is supported by the translation mechanism.
8. The surgical robot according to claim 1 , wherein the joystick is configured to operate the arm in one of a translation mode in which the arm moves a medical device attached at a tip end of the arm such that a tip end of the medical device moves on a predetermined plane and a rotation mode in which the arm moves the medical device such that the medical device rotates about the tip end of the medical device.
9. The surgical robot according to claim 1 , wherein
the joystick is configured to operate the moving direction and a moving speed of the arm;
the surgical robot further comprises a controller configured to control the arm based on an input signal from the joystick; and
the controller is configured to perform a control to reduce a change in the moving speed of the arm by performing at least one of setting an upper limit for the input signal from the joystick or smoothing the input signal from the joystick.
10. The surgical robot according to claim 1 , wherein the operation unit includes a switch unit configured to operate movement of a medical device attached at a tip end of the arm by the arm such that a tip end of the medical device moves along a longitudinal direction of the medical device.
11. A surgical robot comprising:
a robot arm including a plurality of joints, the robot arm being configured to allow a medical device to be attached to a tip end thereof; and
an operation unit supported by the robot arm; wherein
the operation unit includes:
a joystick positioned on an end face of the operation unit and configured to operate the robot arm; and
an enable switch positioned on a peripheral surface of the operation unit and configured to allow movement of the robot arm by being pressed; and
the enable switch and the joystick are arranged apart from each other within a range to facilitate operation by fingers of one hand of an operator in the operation unit.
12. The surgical robot according to claim 11 , wherein
the operation unit includes a mode switch configured to switch an operation mode of the joystick; and
the mode switch is configured to be operated to switch between a translation mode in which the robot arm moves the medical device such that a tip end of the medical device moves on a predetermined plane, and a rotation mode in which the robot arm moves the medical device such that the medical device rotates about the tip end of the medical device.
13. The surgical robot according to claim 11 , wherein
the operation unit includes a pair of the enable switches provided on opposite sides of an outer peripheral surface of the operation unit; and
at least one of the pair of enable switches is configured to allow the movement of the robot arm by the joystick when the operator grasps the outer peripheral surface of the operation unit and presses the at least one of the pair of enable switches.
14. A surgical robot comprising:
a robot arm including an arm portion including a plurality of joints, and a translation mechanism provided on a tip end of the arm portion, the translation mechanism being configured to allow a medical device to be attached thereto, the translation mechanism being configured to translate the medical device relative to the arm portion; and
an operation unit supported by the robot arm; wherein
the operation unit includes:
a switch unit configured to operate the translation mechanism; and
an enable switch provided on a peripheral surface of the operation unit and configured to allow movement of the robot arm by being pressed; and
the enable switch and the switch unit are arranged apart from each other within a range to facilitate operation by fingers of one hand of an operator of the operation unit.
15. The surgical robot according to claim 14 , wherein the operation unit is supported by the translation mechanism so as to be adjacent to the medical device.
16. The surgical robot according to claim 14 , wherein the switch unit includes a first switch configured to translate the medical device in a first direction parallel to a longitudinal direction of the medical device, and a second switch configured to translate the medical device in a second direction opposite to the first direction.
17. The surgical robot according to claim 14 , wherein the operation unit includes a joystick configured to operate the robot arm.
18. The surgical robot according to claim 17 , wherein
the operation unit includes a mode switch configured to switch an operation mode of the joystick; and
the mode switch is configured to be operated to switch between a translation mode in which the robot arm moves the medical device such that a tip end of the medical device moves on a predetermined plane, and a rotation mode in which the robot arm moves the medical device such that the medical device rotates about the tip end of the medical device.
