Abstract
A medical manipulator includes: a surgical instrument unit having an effector; and a surgical instrument drive unit provided detachably with respect to the surgical instrument unit. The surgical instrument drive unit includes: a pair of input members configured to advance and retract in opposite directions to each other; and a driving source configured to advance and retract the pair of input members. The surgical instrument unit includes: a first transmission member configured to move in the same direction as one of the pair of input members; a second transmission member configured to move in the same direction as another of the pair of input members; and a first inversion interlocking member engaged with the first transmission member and the second transmission member.
Claims7
A medical manipulator comprising:
- a surgical instrument unit having an effector configured to manipulate a target object;
- and
- a surgical instrument drive unit provided detachably with respect to the surgical instrument unit and configured to supply a driving force for driving the effector,
- wherein the surgical instrument drive unit comprises:
- a pair of input members disposed at one end of the surgical instrument drive unit in an attachment and detachment direction to the surgical instrument unit and configured to advance and retract in opposite directions to each other, and configured to transmit the driving force in an advance direction upon advance toward the surgical instrument unit;
- and
- a driving source configured to advance and retract the pair of input members, and
- the surgical instrument unit comprises:
- a first transmission member opposite to one of the pair of input members and supported so as to advance and retract in one end of the surgical instrument unit in the attachment and detachment direction to the surgical instrument drive unit, configured to receive the driving force by the one of the pair of input members and move in the same direction as the one of the pair of input members, and connected to the effector in the other end of the surgical instrument unit in the attachment and detachment direction;
- a second transmission member opposite to the other of the pair of input members and supported so as to advance and retract in the one end of the surgical instrument unit in the attachment and detachment direction to the surgical instrument drive unit, and configured to receive the driving force by the other of the pair of input members and move in the same direction as the other of the pair of input members;
- and
- a first inversion interlocking member engaged with the first transmission member and the second transmission member, and configured to transmit a moving amount of one of the first transmission member and the second transmission member to the other of the first transmission member and the second transmission member while inverting a moving direction.
