A surgical instrument that includes a first jaw that has a pair of laterally aligned vertical slots formed in a proximal end portion thereof. Each vertical slot includes an open upper end. A second jaw is movably supported for selective pivotal travel relative to the first jaw between a fully open and a fully closed position. Pivot members protrude laterally from the second jaw and are each received in a corresponding one of the vertical slots in the first jaw such that the pivot members may pivot therein. A retainer member is configured to operably engage the proximal end portion of the first jaw and retain the pivot members in the corresponding vertical slots as the second jaw moves between the fully open and the fully closed positions.

Surgical instrument is provided. The surgical instrument is capable of being operated manually or automatically for use in laparoscopic surgery or various surgeries and includes a locking device capable of locking and/or unlocking at least one operation.

An endoscope treatment tool includes: a forceps having a first forceps piece and a second forceps piece; and a joint. The second forceps piece includes a forceps cup, a first tooth, a second tooth, a third tooth, a fourth tooth. A length from a tip of the first tooth to a tip of the second tooth in a longitudinal direction defines a first length, a length from the tip of the first tooth to a tip of the third tooth in the longitudinal direction defines a second length, and the first length is shorter than the second length. A length from the tip of the first tooth to a tip of the fourth tooth in the longitudinal direction defines a third length and the second length is shorter than the third length.

A surgical forceps includes a housing having a movable handle coupled thereto and movable between an initial position and a compressed position. A drive bar is operably coupled to the movable handle such that movement of the movable handle between the initial and compressed positions effects longitudinal translation of the drive bar. The drive bar further includes a coupling member disposed at a distal end thereof. An end effector assembly includes first and second jaw members movable between spaced-apart and approximated positions. Each jaw member defines a cam slot. A cam pin is slidably disposed within the cam slot of each of the jaw members. The coupling member is configured to releasably engage the cam pin such that movement of the movable handle between the initial position and the compressed position effects movement of the jaw members between the spaced-apart position and the approximated position.

A treatment device includes a shaft extending along a longitudinal axis and including a plurality of segments arranged along the longitudinal axis, a treatment portion at a distal-end side of the shaft, an operation portion at a proximal-end side of the shaft, and an imaging device. A first segment of the plurality of segments is at the distal-end side of a second segment of the plurality of segments and is rotatably attached to the second segment at a first pivot point. The imaging device is provided in the second segment. The first segment is rotatable about the first pivot point relative to the second segment such that a longitudinal axis of the first segment intersects a longitudinal axis of the second segment at a first angle and at least a part of the treatment portion enters a field of view of the imaging device.

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 comprises a jaw assembly having atraumatic pads to reduce force on grasped tissue. An actuator is movable within the elongate shaft to actuate jaws of the jaw assembly responsive to 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 also utilizes forces stored with the integrated extension element to provide a dynamic amount of force used to grasp the tissue when the tissue volume decreases while in the jaws.

A surgical instrument includes an end effector, and a shaft assembly. The end effector includes an ultrasonic blade, a rotating body, and a clamp arm movable between an open and a closed position. The shaft assembly extends along an axis and includes clamp arm clocking assembly and a clamp arm pivot assembly. The clamp arm clocking assembly can drive the rotating body and the clamp arm between a first clocked position and a second clocked position. The clamp arm pivot assembly includes an actuator body defining a track, where the actuator body can actuate to drive the clamp arm between the open position and the closed position while the actuator body is in a rotational position relative to the ultrasonic blade. The track houses a portion of the clamp arm in the first clocked position and the second clocked position while the actuator body is in the rotational position.

The invention relates to a medical instrument having a hollow shaft, whose proximal end can be connected to an operating unit and having a tool tip arranged at the distal end of the shaft having a tool arranged at the distal end of the tool tip, wherein the tool has two jaw parts , which can be pivoted relative to one another and wherein the jaw parts are pivoted via actuating elements, which are mounted so as to be axially displaceable in the shaft and which can be actuated on the proximal side via the operating unit and wherein the tool tip can be pivoted via a joint mechanism relative to the longitudinal axis of the shaft.

In order to provide a medical instrument, which ensures a uniform transmission of tensile and compressive forces even via the pivot region to the tool tip, it is proposed according to the invention that the pivotable jaw parts are each coupled via an articulated drive element to the distal end of an actuating element mounted so as to be axially displaceable in the shaft such that the articulated drive element spans the region of the joint mechanism between the distal end of the shaft and the proximal end of the tool tip.

A clamping system having a clamp head, forceps, and a mechanical actuator. The clamp head has a first clamp or arm, a second clamp arm, a tubular neck, and a drive shaft that extends through the tubular neck. The first clamp arm is moved relative to the second clamp arm by selectively rotating the drive shaft. The forceps have a jaw section. The jaw section has a ring clamp that is sized to receive and retain the tubular neck on the clamp head. A mechanical actuator attaches to the forceps. The mechanical actuator has an elongated shaft that aligns with the drive shaft of the clamp head when the ring clamp is closed around the tubular neck of the clamp head. The alignment enables the mechanical actuator to engage the drive shaft and turn the drive shaft when the mechanical actuator is manipulated.

A surgical instrument includes a shaft and a pair of jaw members disposed on the shaft and extending from an at least partially spherical element. The jaw members are moveable in pitch and yaw relative to the center of the sphere in response to actuation forces applied to a proximal drive mechanism of the instrument. The surgical instrument may include a manually operated handle for manual input of actuation forces by a user, or it may be removably mounted to a drive component of a robotic system such that its proximal drive mechanism is operatively engaged with actuators that generate mechanical output that is transferred to the proximal drive mechanism.
