  • Patent number: 8465495
    Abstract: A surgical tool for tensioning a flexible member of a vertebral device, the flexible member having at least one end portion to which tension is applied. The surgical tool includes a longitudinal member having a longitudinal axis, a first end provided with an element for securing in rotation at least one end portion of the flexible member with the first end of the longitudinal member, and a second end provided with a handling element. The surgical tool also includes a guiding structure comprising a first end adapted to be applied against the body of the vertebral device, and at least one guiding element for guiding in rotation the longitudinal member about the longitudinal axis. The guiding structure maintains the longitudinal axis of the longitudinal member with respect to the body, whereby the rotation of the longitudinal member with the handling element produces the tensioning of the flexible member.

  • Patent number: 8435262
    Abstract: Various exemplary methods and devices are provided for tensioning suture. The methods and devices are particularly useful in surgical suturing applications in which it is desirable to maintain tension on suture being delivered, yet to allow the tension to be released as desired without retracting the suture. Thus, when tension is released, a length of suture extended from the device can remain extended without any tension being applied thereto. Tension is only applied to any additional length of suture that is extended from the device. The tension applied to the suture is proportional to the length of the suture extended from the device until the tension is released and reset.

  • Publication number: 20130110122
    Abstract: A surgical guide wire or K-wire and method of use are provided. The K-wire, or guide wire, has opposite end portions and a shank portion in between. One end portion has a deformable end portion that, once outside of a confining guide passage, can be deformed to present a projected forward facing area that is larger than the transverse cross section of the K-wire, or guide wire, while in the passage. The increased area will provide increased resistance to additional forward axial movement into the surgical site.

  • Patent number: 7981114
    Abstract: A device for installation of a guide wire for a drilling tool in a correct positional arrangement in a bone. The device includes a tissue protection sleeve, which has at one end a laterally projecting grip or handle. A trocar is provided, which trocar can be introduced into the tissue protection sleeve from the handle end and whose other end is closed. The trocar is rotatable in the tissue protection sleeve and has a central bore hole and a plurality of eccentric axially parallel bore holes, through which a guide wire can be passed. A second handle is provided which extends approximately in the same direction of the first handle and whose one end engages the end of the trocar situated the outside of the tissue protection sleeve, so that the normally freely rotatable trocar is fixed in the direction of rotation relative to the tissue protection sleeve, when both handles are manually clamped against each other.

  • Patent number: 7947064
    Abstract: The disclosure relates to systems and methods of spinal stabilization. Embodiments include methods of delivering a rod having a non-circular cross-sectional profile using a wire having an accommodating non-circular cross-sectional profile to inhibit movement of a rod relative to the wire. A surgical system can comprise a first sleeve advanced via a first incision to a vertebra, a second sleeve advanced via a second incision to another vertebra, a wire having a non-circular cross-sectional profile advanced via a third incision to the vertebrae and passed through the collars of bone fastener assemblies to extend from a fourth incision. A rod or a segment of a rod having a corresponding non-circular cross-sectional profile may be aligned with the wire and advanced and coupled with the vertebrae to stabilize the spine. After the rod is securely seated in the collars, the wire may be withdrawn from the body.

  • Patent number: 7938832
    Abstract: Fusion of cervical spinal vertebrae with one or more fixation devices can be accomplished with the described tools and methods. For example, a guidewire introducer can include a tubular introducer cannula and a handle. The handle can be angularly offset from the introducer cannula such that positioning of the introducer on the cervical spine does not interfere with a patient's head. A sheath assembly can include inner and outer sheath bodies and a handle. The handle is angularly offset from the sheath bodies such that the sheath assembly can be applied to the cervical spine without interference to the patient's head. The sheath body can be curved or straight. Various tools such as drills, tapping devices, compression tools, and pin release tools can be applied to the cervical spine through the sheath body to apply the fixation device. The tools can include elongate flexible shafts.

  • Publication number: 20110071537
    Abstract: Disclosed is an intra-medullary rod, including: a cylindrical body made of an X-ray transmitting material; a plurality of wires, which are made of a material that does not transmit X-ray and are deposited at regular intervals along a surface of the cylindrical body in the circumferential direction, being extended in an axial direction in a spiral shape, wherein each of the wires is made in a way that a starting end and a terminating end of the cylindrical body are connected by the shortest distance along the outer surface thereof. In a fluoroscopic image of the cylindrical body, a distance from a reference position to an intersection location of a pair of the wires corresponds to an amount of rotational angle of the intra-medullary rod. By digitizing the intersection location, the rotational angle of the intra-medullary rod is measured.

  • Patent number: 7901412
    Abstract: The invention facilitates the fixation of bone fractures. In a particular embodiment, a method for fixing bone fractures comprises the steps of: inserting a head component coupled to a wire through a first bone portion and anchoring the head component in a second bone portion, inserting a cap over the wire toward the head component until the cap contacts the second bone portion, and applying pressure to the wire using a tensioner to reduce the distance between the first bone portion and the second bone portion. The excess wire beyond the cap can then be removed.

  • Patent number: 7892238
    Abstract: Systems, devices, and methods suitable for use with procedures performed at least partially percutaneously are provided. In some procedures, two or more access devices for providing access to adjacent surgical locations within a patient are used. Certain embodiments of the access device comprise an elongate body having a distal end with one or more cutouts. The cutouts on adjacent access devices are generally aligned with each other to permit passage of a portion of a fixation element from one access device to the other access device. A fastener with an elongated removable head may be delivered to the surgical site through the access device. After a distal end of the fastener is secured to the surgical site, a portion of the elongated housing is detached from the remainder of the fastener and removed from the patient.

  • Publication number: 20110022054
    Abstract: A tensioner for a tightening a surgical knot has a squeeze handle and a pair of jaw arms that pivot from a common point behind the handle. The jaw arms have a jaw clamp at the distal tip to clamp onto the suture material, and a release handle at the proximal or butt end. A spreader or distractor mechanism may be a pantographic arrangement of struts joined to anchor points on the jaw arms. This converts axial motion of an actuator rod into a lateral distractive force. A tension gauge in the handle indicates the amount of tension being applied to the suture material.
