An ultrasonic instrument includes a body, an actuation assembly, a shaft assembly, and an end effector. The actuation assembly includes an activation member that is operable to move in a first direction to select a mode of operation. The shaft assembly extends distally from the body and includes an acoustic waveguide. The end effector includes an ultrasonic blade that is in acoustic communication with the acoustic waveguide. The activation member is operable to move in a second direction to activate the end effector in a mode of operation selected by movement of the activation member in the first direction.

Drive systems and methods of use are disclosed herein for performing medical procedures on a patient. The drive systems include various handle types and triggers for controlling catheters and end effectors. The various handle types include a flexible handle and ambidextrous handles that can alter the handedness of the handle for particularized use. The handles drive articulation sections of the catheter and end effectors with various degrees of freedom, and include locks for holding the catheter and/or end effector in place. The catheter systems include structures for allowing degrees of freedom, such as notches, mechanical interlocks, and articulation joints. In addition, the catheters articulate via cables or fluids.

A surgical stapling instrument including a staple sled which can be advanced and/or retracted relative to first and second jaw members, wherein the staple sled can be configured to deploy staples from a staple cartridge in one of the first and second jaw members. In at least one embodiment, the other of the first and second jaw members can include an anvil having at least one forming surface which can be configured to deform the staples as they are deployed from the staple cartridge. In at least one form of the invention, the anvil can be movably adjustable relative to the staple cartridge in order to adjust the distance in which the staples are deformed. In various embodiments, the anvil can be adjusted by a slidable adjusting plate and/or a rotatable cam.

Surgical instruments and methods of minimally invasive surgery are provided. The device may include two proximal handles each sized for a surgeon's hand, the two handles in fixed relative positions, and a distal probe attached to the handles. The probe can include a distal cutting member and contain or receive an imaging device. The system can be used for cutting anatomic members, such as ligaments, during minimally invasive surgical procedures, for example, performing endoscopic ligament release surgery, such as carpal tunnel release, plantar fasciotomy, gastrocnemius release, cubital tunnel release, and tarsal tunnel release surgery, and similar surgical procedures on anatomic members.

Surgical trays, tools and methods for use in hip replacement surgery wherein the hip replacement prosthesis is a reverse hip prosthesis. The trial components, specialized tools and methods of the invention enable a surgeon to identify the optimum components of the reverse hip prosthesis for implantation in a patient based on the sizes and angles best adapted to the patent's anatomy.
