  • Patent number: 8211012
    Abstract: A tissue retractor system includes first and second arms extending from a support assembly, and third and fourth arms extending from a support mechanism. Each arm includes a proximal span, a distal span, and a blade support between the proximal span and distal span. The retractor system features retractor units that can be used independently or in a nested arrangement. The system also includes instruments for inserting a spinal rod. A method for implanting a spinal rod through an incision includes the steps of inserting the spinal rod through a dividable tube, turning the rod subcutaneously toward a rod receiving anchor and advancing the rod subcutaneously toward the rod receiving anchor.

  • Patent number: 8206293
    Abstract: The retractor system for use in spinal surgery and other types of surgical procedures that is a simple and efficient solution for minimally invasive access to thoracolumbar spine is disclosed. The fully customizable design allows the surgeon to independently angle the retractor blades and expand the retractor in both cephalad-caudal and medial-lateral directions. With an offering of a range of blade lengths, access can be tailored to the patient's anatomy. Auxiliary instruments such as the retractor inserter, universal hex driver and blade removal instrument allow quick and controlled access to the surgical site. The retractor system provides versatility and control ensuring minimal tissue trauma.

  • Patent number: 8152720
    Abstract: A blade assembly has a blade body and a blade body surround. A retractor attachment structure is attached to the blade body at the first end portion thereof extending from an exterior surface thereof. The retractor attachment structure is configured for having one of the blade body mounting structures of the retractor engaged therewith in a manner whereby the blade body is independently pivotable about and translatable along the blade body mounting structure. An alignment member protrudes from an interior surface of the blade body adjacent its first end portion. A slot extends through the blade body at its first end portion. The blade body surround and the blade body jointly form a generally cylindrical-shaped structure when the blade body is in a seated position within the slot. The cylindrical structure defines a central passage extending between the first and second end portions of blade body surround.

  • Patent number: 8142355
    Abstract: A retractor for use in surgical operations comprises a pair of blade assemblies which are adapted to open about a set of axes that are not parallel to a third spatial axis. The retractor further comprises a pair of arms, which are adapted to move the pair of blade assemblies apart from one another in the third spatial axis. In operation, the blade assemblies are closed to assume a low profile, inserted into a relatively small incision, and stretched apart from each other, thereby stretching the skin about the incision to form an aperture longer than the incision. The blade assemblies are then opened by rotating the blades about the set of axes, thereby stretching the skin around the incision in a second direction that is substantially perpendicular to the first direction (i.e. the direction of the incision.) The retractor thus forms an aperture for passage of surgical instruments and viewing of the surgical field by surgical personnel.

Blade depth of the retractor is set buy sliding the retractor onto the blade extending tower such that the mating features of the blade extending tower engage the blades or the retractor, stopping the blades progression while the rest of the retractor continues along the length of the column. Thus the blades of the retractor are extended from the retractor to a depth determined by the configuration of the blade extending tower.

  • Publication number: 20090198107
    Abstract: Devices for use during surgical or non-surgical procedures can move items from the field of view or work space. Retraction of items during any surgical or non-surgical procedure moves the items from the field of view or work space. The flexibility and compactness of a retraction device can make it suitable for surgery, especially minimally invasive surgery (MIS).

  • Patent number: 7524285
    Abstract: Methods and devices retract tissue for minimally invasive surgery in a patient. A retractor includes a working channel formed by a first portion and a second portion. The first and second portions are movable relative to one another from a first configuration for insertion that minimizes trauma to skin and tissue to an enlarged configuration after insertion to further retract skin and tissue in a minimally invasive manner. Instruments are engageable to the first and second portions and operable to move the first and second portions relative to one another.

  • Publication number: 20080188718
    Abstract: A surgical retractor may be provided for a surgical procedure such as spinal surgery. The surgical retractor may include a separator, a first and second blade holder coupled to the separator, and blade assemblies coupled to the blade holders. The separator may move the blade holders to change the position of the first blade holder relative to the second blade holder. The blade assemblies may retract tissue of a patient. An activator of a blade holder may be used to rotate a first blade of the blade assembly. Rotating the first blade tilts the blade assembly to create a larger opening at a distal end of the retractor. In some embodiments, side blades may be placed in the retractor.

  • Patent number: 7270632
    Abstract: A surgical retractor includes a pair of small grips that are disposed at the ends of arms that can be moved toward or away from each other. The grips engage and separate the sides of an incision that has been made in a patient. A lifting mechanism that can be attached to one of the arms enables one side of the incision to be raised relative to the other side of the incision. The lifting mechanism includes a clamp that can be connected to the retractor and a foot that is connected to the clamp and which is movable relative thereto. The foot is engageable with the patient such that extension of the foot causes a selected grip to be raised. Retraction of the foot permits the selected grip to be lowered. In the preferred embodiment, the foot is disposed at one end of a notched rack; a rotatable pinion is in contact with the notches to extend and contract the rack; and a pivotally movable pawl permits movement of the rack in one direction and prevents movement of the rack in the other direction.

  • Patent number: 7144368
    Abstract: The present invention provides methods and apparatus in which a surgical retractor comprises a plurality of mechanically coupled tissue retaining walls that are guided into position along one or more guides previously implanted into the patient. The walls are preferably coupled by pivots, so that separating some of the walls from one another opens an operating space. There are preferably two guides, which are driven or screwed into the pedicles of vertebrae, or other bone. Oversized channels are best disposed in a frame, which also serves to hold lock the walls apart. Various convenience features are contemplated including a web disposed between the walls, which expands as the walls are separated. Also contemplated are projections from near the bottoms of one or more of the walls, which can alternatively or additionally help to hold the underlying tissue in place.
