  • Patent number: 9078707
    Abstract: A screw system includes a screw and a washer assembly captive to the screw. The washer assembly is polyaxially pivotable relative to the screw. The screw may be freely rotated in one direction relative to the washer assembly, but frictionally binds with the washer assembly when rotated in a second direction. A cannula insertion system includes an instrument and a cannula. The instrument may include a dilator. The cannula insertion system may have a locked setting in which the dilator is fixed relative to the cannula, and an unlocked setting in which the dilator is slidable relative to the cannula. A surgical method uses the cannula insertion system to implant the screw system.

  • Patent number: 9011319
    Abstract: A single body port or body flange access device having an oval shape and associated stabilizer anchor for performing laparoscopic surgery is disclosed. The device is slipped into the body anchor stabilizer first so that the anchor stabilizer lifts up fat and peritoneum inside the body thereby keeping the operating area clear and acting to hold the body flange in place. The device further has a plurality of crisscrossing conduits assuming the shape of a cone through which surgical instruments may be inserted. The instruments are manipulated so that triangulation is obtained using one patient body flange while standard surgical procedures are performed on the patient. Due the oval shape of the device, the device minimally rotates while instruments are manipulated.
