  • Publication number: 20180271531
    Abstract: Magnetic anastomosis devices constructed from magnetic segments coupled together with members that help the devices spontaneously transform from a linear delivery configuration to a polygonal deployment configuration. When two devices are joined together over tissue(s), the compressive force causes the tissue(s) to necrose and form an anastomosis. By altering the arrangement of the magnetic poles of the magnetic segments in the devices, the magnetic interaction between paired devices can be altered. This property gives surgeons flexibility in choosing how much attractive force the devices will experience during a procedure.

    Abstract: A device for applying a constrictive force about a limb includes a reel based device, a tension member, and a force application component. The reel based device includes a housing, a spool positioned within the housing, a load holding mechanism that enables the spool to rotate in a tightening direction within the housing and that prevents the spool from rotating in a loosening direction within the housing, and a knob that is coupled with the spool so that a rotation of the knob causes the spool to rotate in the tightening direction. The tension member is coupled with the spool so that as the spool rotates in the tightening direction, the tension member is wound about the spool. The force application component is coupled with the tension member so that as the tension member is wound about the spool, the force application component constricts about the limb.

  • Publication number: 20180271543
    Abstract: A device for minimally invasive bone harvesting surgery described herein includes a cutter, a sleeve, and a drive control system. The cutter includes a head and a spiral conveying portion. An external screw thread is disposed on a surface of the spiral conveying portion, the sleeve is sleeved on the cutter, and the head and at least a part of the screw thread of the surface of the spiral conveying portion are exposed from the sleeve. The drive control system drives and controls the cutter to work. The device for minimally invasive bone harvesting surgery in this invention only needs a very tiny skin incision and bone window, cuts or grinds cancellous bone to bone fragments and then conveys them through a screw thread channel, which realizes the oriented conveying of the harvested bone.
