Provided is an end tool including: a first jaw configured to rotate independently; a J11 pulley coupled with the first jaw and configured to rotate around a first axis formed at an end tool hub; a J16 pulley formed at one side of the J11 pulley and configured to rotate around a second axis formed at one side of the first axis; a J12 pulley and a J14 pulley formed at one side of the J16 pulley, and configured to rotate around a third axis formed at a predetermined angle with the first axis. The end tool may further include: a first jaw wire configured to at least partially contact the J12 pulley, the J11 pulley, the J16 pulley, and the J14 pulley; a J16 pulley formed between the J11 pulley and a J12 pulley/a J14 pulley; and the first jaw wire is located on an internal tangent of the J11 pulley and the J16 pulley.

A method of manufacturing a two-part sealing plate of a jaw member of an end effector assembly includes: fabricating a series of grooves through an upper plate of a two-part sealing plate of a jaw member; securing a lower plate to a non-tissue engaging side of the upper plate such that an upper surface of the lower plate defines a corresponding bottom surface of at least one of the series of grooves; and securing the seal plate to a support base of the jaw member.

An actuator handle for a hand-held surgical tool, the actuator handle comprising: a body part adapted to be gripped by a user's hand, the body part having an end effector mounted or mountable thereon; an actuating member alongside the body part and arranged to be operably moveable by a single finger of the said hand, in a substantially linear manner between first and second positions relative to the body part, for actuating the end effector in use; and one or more coupling components coupled to the actuating member, for mechanically transmitting motive force from the actuating member to the end effector upon movement of the actuating member between the first and second positions by the user in use. A surgical clip, for example for use in aneurysm clipping, is also provided, the clip comprising: first and second clipping arms that are mutually openable and closable; biasing means arranged to resiliently bias the first and second clipping arms into a closed configuration; and first and second engagement fixtures respectively coupled to the first and second clipping arms and arranged such that first and second gripping arms of a complementary surgical clip deployment tool can grip the clip and open the clipping arms by applying a lateral force to the first and second engagement fixtures; wherein each of the first and second engagement fixtures comprises at least part of a ball or at least part of a loop or cup, with which each of the arms of said surgical clip deployment tool can engage in a substantially ball-and-socket manner.

An endoscope treatment tool includes: a distal end part; an operating part into which an operation to the distal end part is input; and a soft portion that connects the distal end part and the operating part, and the operating part includes a fixing unit that attaches the operating part to an endoscope, and an operating part body that is capable of moving forward and backward with respect to the fixing unit and that is rotatable along a plane orthogonal to the forward and backward movement direction, and has a friction mechanism that generates a first frictional force between the fixing unit and the operating part body in a rotation direction of the operating part body and that generates a second frictional force between the fixing unit and the operating part body in the forward and backward movement direction, which is different from the first frictional force.

A surgical instrument is provided having an actuator mechanism with an integrated extension element. The surgical instrument comprises a handle assembly, an elongate shaft, and an end effector. The end effector can comprise a jaw assembly having atraumatic pads positioned thereon to reduce force on grasped tissue. An actuator is movable within the elongate shaft to actuate jaws of the jaw assembly responsive to movement of a movable handle of the handle assembly. The actuator can have an integrated extension element that allows the actuator to translate within the elongate shaft upon application of a relatively low force and translate and extend upon application of a relatively higher force to the actuator to limit the force applied by the jaw assembly. The actuator is also able to utilize force stored with the integrated extension element to provide a dynamic amount of force used to grasp the tissue in scenarios where the tissue volume decreases while in the jaws.

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.

A surgical instrument system is disclosed comprising a handle, an elongate shaft selectively attachable to the handle, a battery pack replaceably attachable to the handle, and an end effector extending distally from the elongate shaft. In various instances, the battery pack comprises a power source couplable to the motor and a display. The elongate shaft comprises a processor and a memory couplable to the processor. In various instances, the memory comprises a control program which, when executed, causes the processor to initiate a desired function. In various instances, the end effector comprises a sensing circuit configured to detect a condition of the end effector. The sensing circuit is in signal communication with the processor.

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; and 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.

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