Abstract
A surgical treatment instrument includes a holdable housing, a shaft, an end effector configured to perform a bending movement with respect to the shaft, a rotor configured to rotate about a rotation axis in response to an operation input performed through an operation member, and a transmission member configured to transmit a driving force for causing the end effector to perform the bending movement to the end effector. The operation member and the transmission member are configured to rotate together with the shaft and the end effector in response to the operation input, and the rotor is configured to not rotate together with the shaft and the end effector when the operation input is performed.
Claims11
A surgical treatment instrument comprising:
- an elongated member having a longitudinal axis, the elongated member extending along the longitudinal axis from a proximal side to a distal side of the elongated member;
- a housing connected to the elongated member at a distal side of the housing;
- an end effector attached to the distal side of the elongated member, the end effector being configured to bend relative to the elongated member;
- a first operator configured to rotate the elongated member and the end effector about the longitudinal axis with respect to the housing;
- a second operator attached to the housing, the second operator being configured to bend the end effector relative to the elongated member;
- a rotor having a rotation axis parallel to the longitudinal axis of the elongated member, the rotor being provided inside the housing and configured to rotate about the rotation axis of the rotor in response to an operation performed by the second operator to bend the end effector;
- and
- a transmitter connected to the rotor and the end effector, the transmitter being configured to transmit a driving force to the end effector causing the end effector to bend, in response to the rotor rotating about the rotation axis of the rotor based on the operation performed by the second operator to bend the end effector,
- wherein in response to performing the operation by the first operator to rotate the elongated member and the end effector:
- the second operator and the transmitter are configured to rotate about the longitudinal axis with respect to the housing together with the elongated member and the end effector, and
- the rotor is configured to not rotate, together with the elongated member and the end effector, with respect to the housing about the longitudinal axis.
