Abstract
Provided are surgical instruments, and more particularly, surgical instruments that may be manually operated to perform laparoscopic operations or various surgical operations.
Claims306
A surgical instrument comprising:
- an end tool formed to rotate in two or more directions;
- an operator controlling an operation of the end tool;
- an operating force transmitter comprising one or more wires and one or more pulleys transmitting an operation of the operator to the end tool;
- and
- a connector having one end portion coupled to the end tool and the other end portion coupled to the operator to connect the operator and the end tool,
- wherein
- at least a portion of the operator is formed to extend toward the end tool, and
- when the operator is rotated in the two or more directions, the end tool rotates in substantially the same direction as an operation direction of the operator.

An end tool of a surgical instrument, comprising:
- a first jaw and a second jaw operating independently of each other;
- and
- an end tool control member comprising:
- a J11 pulley coupled with the first jaw and formed to rotate around a first axis;
- a J12 pulley and a J14 pulley formed to rotate around an axis making a predetermined angle with the first axis and formed to face each other;
- a J13 pulley and a J15 pulley formed to rotate around an axis making a predetermined angle with the first axis and formed to face each other;
- a J21 pulley coupled with the second jaw and formed to face the J11 pulley;
- a J22 pulley and a J24 pulley formed to rotate around an axis making a predetermined angle with the first axis and formed to face each other;
- and
- a J23 pulley and a J25 pulley formed to rotate around an axis making a predetermined angle with the first axis and formed to face each other,
- wherein
- at least a portion of a first jaw operating wire sequentially contacts the J13 pulley, the J12 pulley, the J11 pulley, the J14 pulley, and the J15 pulley to rotate the J11 pulley and the J15 pulley, and
- at least a portion of a second jaw operating wire sequentially contacts the J23 pulley, the J22 pulley, the J21 pulley, the J24 pulley, and the J25 pulley to rotate the J21 pulley and the J25 pulley.

A surgical instrument comprising:
- an end tool comprising a first jaw and a second jaw operating independently of each other;
- an operator controlling operations of the first and second jaws of the end tool;
- an operating force transmitter comprising a first jaw operating wire connected with the operator to transmit a rotation of the operator to the first jaw and a second jaw operating wire connected with the operator to transmit a rotation of the operator to the second jaw;
- and
- a connector having one end portion coupled to the end tool and the other end portion coupled to the operator to connect the operator and the end tool,
- wherein
- at least a portion of the operator is formed to extend toward the end tool, and
- an operation direction of the operator and an operation direction of the end tool are intuitively identical to each other.

A surgical instrument comprising:
- an end tool comprising a first jaw and a second jaw operating independently of each other;
- an operator controlling operations of the first and second jaws of the end tool;
- an operating force transmitter comprising a pitch wire connected with the operator to transmit a pitch motion of the operator to the end tool, a yaw wire connected with the operator to transmit a yaw motion of the operator to the end tool, and an actuation wire connected with the operator to transmit an actuation motion of the operator to the end tool;
- and
- a connector having one end portion coupled to the end tool and the other end portion coupled to the operator to connect the operator and the end tool,
- wherein
- at least a portion of the operator is formed to extend toward the end tool, and
- an operation direction of the operator and an operation direction of the end tool are intuitively identical to each other.
