Claims20
An instrument for surgery comprising:
- an end tool comprising at least one jaw, and an end tool jaw pulley coupled to the at least one jaw and configured to rotate around a jaw rotation shaft, the end tool configured to rotate in at least one directions;
- a manipulation part configured to control rotation of the end tool in the at least one direction, the manipulation part comprising
- a yaw manipulation part configured to control a yaw motion of the end tool, the yaw manipulation part comprising a manipulation part yaw pulley configured to rotate around a yaw rotation shaft;
- a power transmission part connected to the manipulation part, the power transmission part comprising at least one jaw wire configured to transmit rotation of the manipulation part to the at least one jaw;
- and
- a connecting part extending in a first direction (X axis), the connecting part being coupled to the end tool at an end portion thereof and coupled to the manipulation part at another end portion thereof so as to connect the manipulation part to the end tool,
- wherein the end tool jaw pulley and the manipulation part yaw pulley have different diameters.

An instrument for surgery comprising:
- an end tool comprising at least one jaw, and an end tool pitch pulley provided at a side of the jaw and configured to rotate around an end tool pitch rotation shaft, the end tool configured to rotate in at least one directions;
- a manipulation part configured to control rotation of the end tool in the at least one direction, the manipulation part comprising
- a pitch manipulation part configured to control a pitch motion of the end tool, the pitch manipulation part comprising a manipulation part pitch pulley configured to rotate around a pitch rotation shaft;
- a power transmission part connected to the manipulation part, the power transmission part comprising at least one jaw wire configured to transmit rotation of the manipulation part to the at least one jaw;
- and
- a connecting part extending in a first direction (X axis), the connecting part being coupled to the end tool at an end portion thereof and coupled to the manipulation part at another end portion thereof so as to connect the manipulation part to the end tool,
- wherein
- the end tool pitch pulley and the manipulation part pitch pulley have different diameters.
