A surgical instrument includes an end effector, a shaft assembly, and a torque wrench integrally connected with the shaft assembly. The shaft assembly has an acoustic waveguide extending therethrough and the end effector projects distally from the shaft assembly. The acoustic waveguide has a proximal end portion configured to rotatably couple with an ultrasonic transducer assembly. The torque wrench is configured to transmit torque applied to the acoustic waveguide up to a predetermined torque. A portion of the torque wrench is configured to deflect upon receipt of torque greater than the predetermined torque. Accordingly, the portion of the torque wrench slips relative to the acoustic waveguide for limiting coupling of the acoustic waveguide to the ultrasonic transducer assembly to the predetermined torque.

Apparatus and methods are provided for performing a medical procedure, such as a laparoscopic appendectomy using a stapler apparatus including a reusable handle portion including a shaft include proximal and distal ends, a disposable end effector attached to the distal end of the shaft of the reusable handle carrying one or more staples. For example, the end effector may include first and second jaws movable relative to one another between open and closed positions, the first jaw carrying a cartridge which includes the one or more staples. A Doppler sensor, a cutting element, and, optionally, a thermal element are also provided on the end effector. The end effector is introduced into a patient's body, tissue is positioned/locked between the jaws, and a plurality of staples are deployed into the tissue. The Doppler sensor is used to confirm that blood flow has discontinued in the stapled tissue, and the cutting element is actuated to sever the stapled tissue.

A surgical suture module for a machine constructed and configured for automatic, continuous suturing for reduced or minimized scarring and reduced suturing time. A surgical suture module for continuous, subcuticular suturing. The module includes a generally circular needle with a needle shaft; a supply of thread; a thread guide; a hook with a hook shank, a holding arm mechanism; and a housing. The needle, rotationally movable between a first position and a second position, is configured to introduce the thread into a tissue. The hook is operable for hooking and lifting the thread in coordination with the needle and the holding arm mechanism is operable for pushing and catching the thread in automatic coordination with the hook. The needle, the hook, and the holding arm mechanism are held in position by the housing and the housing operable to attach to a power supply that provides power to the module.

The present disclosure relates to adapter assemblies for use with and to electrically and mechanically interconnect electromechanical surgical devices and surgical loading units, and to surgical systems including hand held electromechanical surgical devices and adapter assemblies for connecting surgical loading units to the hand held electromechanical surgical devices.

A surgical assembly includes a surgical instrument and a holder. The surgical instrument includes an elongate body and an end effector. The elongate body has a proximal portion and a distal portion that defines a longitudinal axis therealong. The proximal portion is movable relative to the distal portion between a first condition and a second condition. In the first condition, the proximal portion is parallel to the longitudinal axis. In the second condition, the proximal portion is non-parallel to the longitudinal axis. The holder is configured to be coupled to the elongate body to selectively retain the proximal portion of the elongate body in the first condition.

A method of inserting an intervertebral disc implant into a disc space includes accessing a spinal segment having a first vertebral body, a second vertebral body and a disc space between the first and second vertebral bodies. The method includes securing a first pin to the first vertebral body and a second pin to the second vertebral body, using the first and second pins for distracting the disc space, and providing an inserter holding the intervertebral disc implant. The method also desirably includes engaging the inserter with the first and second pins, and advancing the inserter toward the disc space for inserting the intervertebral disc implant into the disc space, whereby the first and second pins align and guide the inserter toward the disc space.

A surgical device is provided that includes a jaw portion with a first jaw and a second jaw moveable relative to the first jaw. The surgical device also includes a shaft portion coupled to a proximal end of the jaw portion. A driver is configured to cause relative movement of the jaw portion and the shaft portion. The driver may be configured to cause the jaw portion to pivot relative to the shaft portion about a pivot axis that is perpendicular to first and second longitudinal axes defined by the jaw portion and the shaft portion, respectively. The driver may also be configured to cause at least a portion of the jaw portion to rotate relative to the shaft portion about the first longitudinal axis. Advantageously, the surgical device includes a surgical member, e.g., a cutting element and/or a stapling element, disposed within the first jaw.

A reposable surgical clip applier (10) is provided and includes a handle assembly (100), an endoscopic assembly (200) selectively connectable to a housing (102) of the handle assembly (100), and a cartridge assembly (300) selectively loadable in and connectable to the endoscopic assembly (200).

A loading unit includes a shell assembly, a lock collar, and a release collar. The shell assembly has a coupling ring that defines a lock slot and a proximal opening configured to receive a distal end portion of a surgical instrument. The lock collar is disposed about the coupling ring and has a radially extending lock that is configured to be received within the lock slot. The lock collar is transitionable between a locked configuration in which the lock is positioned within the lock slot and an unlocked configuration in which the lock is lifted from within the lock slot. The release collar is disposed about the coupling ring proximal of the lock collar and is transitionable between an unactuated position and an actuated position. The release collar transitioning the lock collar to the unlocked configuration as the release collar is translated from the unactutated position towards the actuated position.

A surgical retractor for retracting body tissue in a therapeutic procedure includes a blade having a body portion and a plurality of elongate elements extending from the body portion. The plurality of elongate elements is separated a distance from one another along a length of the body portion and form one or more gaps therebetween. The plurality of elongate elements is connected by one or more cross connectors transverse to the plurality of elongate elements. The retractor blade is configured to permit movement of a lung being retracted.
