A surgical fastening device provides a mechanism for manually retracting the drive shaft, drive beam, and associated components in the event of a jamming or misfiring condition. The device includes a handle housing from which an elongate shaft extends and an end effector at a distal end of the shaft. The end effector has a cartridge jaw and an anvil jaw in a pivoting arrangement. A drive shaft actuates a drive beam, which acts to drive fasteners from the cartridge jaw into tissue. The device include a first retraction mechanism configured to move linearly and proximally to retract the drive beam and drive shaft, and a second retraction mechanism that likewise is able to retract the drive beam and drive shaft.

A surgical device comprising a staple cartridge, a clamping mechanism configured to clamp patient tissue, a firing member, a manual bailout, an electric motor, a power source, and a control unit is disclosed. The clamping mechanism comprises a first iaw and a second iaw. The firing member configured to engage the first jaw and the second jaw during a closure stroke. The second jaw is moved to the closed position during the closure stroke and the firing member is further configured to eject staples from the staple cartridge during a firing stroke. The manual bailout is configured to retract the firing member through a retraction stroke. The electric motor is configured to drive the firing member. The control unit is configured to monitor a parameter of the electric motor and control the amount of current supplied to the electric motor based on the parameter.

A latch assembly for a surgical instrument includes a lever having a distal engagement section, an intermediate section, and a proximal manipulatable section. The proximal manipulatable section includes an exterior surface including lateral sides, a side wall depending from the exterior surface along the lateral sides of the exterior surface and about a proximal end of the exterior surface, a lip extending from the side wall to define a shelf extending outwardly from the side wall along the lateral sides of the exterior surface and about the proximal end of the exterior surface, and a proximal stop disposed on the shelf at the proximal end of the exterior surface and extending towards the exterior surface.

A multipurpose medical scissor assembly having a first element and a second element arranged in a scissor configuration. The first element has a first blade support section and a first shank section. The second element has a second blade support section and a second shank section. A segment that mimics the shape of the second blade support section is mounted parallel to the second blade support section. Both the segment and the second blade support section terminate with hooked ends that create a forked configuration. The first element, the second element and the parallel segment are preferably all molded of plastic. Metal blades are attached to the first blade support section and to the second blade support section to provide cutting edges.

Disclosed herein are devices (e.g., needles (e.g., hollow needles), hollow staples, articles, apparatuses, and systems), kits, and methods for treating skin and skin conditions, for example, by promoting skin tightening, such as by reducing skin laxity and reducing tissue area or volume.

A method to remove a memory metal orthopedic staple from that is implanted in a bone repair site is disclosed. The orthopedic staple is in its relaxed state and the method includes (a) attaching an inserter tool/cartridge assembly to the orthopedic staple's bridge portion; (b) actuating the inserter tool to change the orthopedic staple from its relaxed state to its insertion state in which the two legs of the orthopedic staple are substantially parallel to each other; and (c) removing the orthopedic staple from the bone repair site.

Devices and methods for manipulating devices such as micro-scale devices are provided. The devices can include a tether of various materials surrounded by a stiff body. The tether interfaces with microscale devices to draw them against the stiff body, holding the microscale devices in a locked position for insertion into or extraction out of tissue. The tensional hook and stiff body are configurable in a multitude of positions and geometries to provide increased engagement. Such configurations allow for a range of implantation and extraction surgical procedures for the device within research and clinical settings.
