Abstract: Provided is an instrument for surgery and, more specifically, to an instrument for surgery which can be manually operated in order to be used for laparoscopic surgery or various types of surgery.

Abstract: According to the present disclosure, provided is a surgical instrument in which an actual motion of bending an end tool or performing a surgical treatment intuitively matches a motion of a manipulation portion corresponding thereto. In detail, to this end, provided are an end tool having various degrees of freedom, a manipulation portion having a structure to enable intuitive manipulation of a motion of the end tool, and a driving force transmission portion for transmitting a driving force of the manipulation portion to the end tool so that the end tool operates as manipulated by the manipulation portion.

Abstract: Provided is a surgical instrument including: an end tool including a first jaw and a second jaw configured to rotate independently; an operator including a pitch operator controlling a pitch motion of the end tool, a yaw operator controlling a yaw motion of the end tool, and an actuation operator controlling an actuation motion of the end tool; an operating force transmitter including a first jaw wire connected with the first jaw to transmit an operation of the operator to the first jaw, a second jaw wire connected with the second jaw to transmit an operation of the operator to the second jaw, and one or more differential members transmitting a rotation of the yaw operator or the actuation operator to the first jaw or the second jaw via the first jaw wire or the second jaw wire; and a connector configured to extend in a first direction (X axis) and 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 the pitch operat

Abstract: Provided is a roll joint member for a surgical instrument. The roll joint member includes a wire guide portion, a guide member including a wire support portion, and a shaft member rotatably coupled to the guide member.

Abstract: Provided is a surgical instrument including an end tool, a connection portion, a frame portion, a bridge portion, a manipulation portion, and a driving force transmission portion. The surgical instrument further includes a guide portion having one end portion provided on the bridge portion and the other end portion provided on the frame portion, surrounding a wire portion in a preset section, and guiding a movement path of the wire portion. The surgical instrument is manually operated for use in laparoscopic surgery or various surgical procedures.

Abstract: The present disclosure relates to an instrument for surgery and, more specifically, to an instrument for surgery which can be manually operated in order to be used for laparoscopic surgery or various types of surgery.

Abstract: Provided is a surgical instrument, in more detail, a surgical instrument that may be manually operated to be used in laparoscopic surgery or various other kinds of surgery. To this end, the present invention provides a surgical instrument including an end tool configured to be rotatable in at least two directions; a manipulator including a pitch operator controlling a pitch movement of the end tool, a yaw operator controlling a yaw movement of the end tool, and an actuation operator controlling an actuation movement of the end tool; a power transfer unit configured to transfer an operation of the manipulator to the end tool; and a connection unit extending in a first direction (X-axis), and connecting the manipulator to the end tool when the end tool is coupled to an end portion of the connection unit and the manipulator is coupled to the other end portion of the connection unit, wherein at least a part of the manipulator extends towards the end tool.

Abstract: Provided are surgical instruments, and more particularly, surgical instruments that may be manually operated to perform laparoscopic operations or various surgical operations.
