  • Publication number: 20240299218
    Abstract: A skin environment management system is provided that controls environmental conditions on a portion of skin of a subject. The system includes a dressing that includes a skin interface, a dressing base attached to the skin interface, and a cover reversibly-openable and connected to the dressing base to together define a volume. The cover sealable to the skin interface, and the dressing is configured to be positioned over the portion of the skin, the dressing defining an environment in the volume surrounding the portion of the skin. The system further includes a pump in fluid communication with the environment by a first tube, the pump configured to apply a reduced pressure vacuum to the environment, and a controller configured to dynamically control operation of the pump. A dressing for use with a skin environment management system is also provided.

  • Patent number: 11452615
    Abstract: A tool for delivery and/or compaction of bone graft material includes a cannula with an inner lumen extending along a longitudinal axis from a hopper end of the cannula to a delivery tip of the cannula. A hopper with an internal volume for storing bone graft material is connected to the hopper end of the cannula with the internal volume of the hopper in communication with the inner lumen of the cannula for delivery of bone graft material from the hopper to the delivery tip of the cannula. An output shaft within the inner lumen extends along the longitudinal axis. The output shaft includes a helical screw thread extending radially outward from the output shaft toward an inner surface of the cannula. An actuator is connected to the hopper and to the output shaft to drive the output shaft rotationally relative to the hopper and to the cannula.

  • Patent number: 9883880
    Abstract: An articulation mechanism for a surgical instrument includes an articulation assembly, a plurality of cables, and a trigger. The cables are coupled to the articulation assembly at a proximal end thereof and extend distally therefrom. The cables are configured to engage an end effector assembly of the surgical instrument at a distal end thereof. The trigger is coupled to the articulation assembly and is selectively moveable from a shipping position to a use position. In the shipping position, the cables are substantially un-tensioned. In the use position, the cables are disposed in an initial tensioned position. In the use position, the trigger is moveable between an unlocked position and a locked position. In the unlocked position, the cables are selectively tensionable to articulate the end effector assembly. In the locked position, the tensions on the cables are maintained to lock the end effector assembly in position.
