  • Patent number: 10398570
    Abstract: A cup and a temporary insert are respectively configured to be tightly press fitted into each other along their periphery. The temporary insert includes a through hole communicating outside with a free space between the outer surface of the temporary insert and the inner surface of the cup. In the through hole can be engaged the threaded end of an impactor, for manipulating the cup when it is being set. A syringe can be engaged, enabling a liquid under pressure to be injected into the free space, thus separating the temporary insert from the cup without any risk of damaging the inner surface of the cup. Thus, the cup can be securely manipulated when it is being set without any risk of damaging the inner surface of the cup.

  • Patent number: 10383661
    Abstract: A system for replacing at least a portion of a natural facet joint includes a fixation member implantable in a vertebra, an inferior facet articular surface and an inferior strut which may be formed separately from the inferior articular surface. The inferior strut has a first end securable to the fixation member and a second end which may comprise a sphere with a hemispherical surface. An attachment mechanism may include a capture feature shaped to receive the second end of the inferior strut, and the mechanism may provide an adjustable configuration, allowing polyaxial adjustment between the inferior articular surface and the second end. A locking member may be actuated to exert force on the second end to provide a locked configuration. The system may further include a superior facet joint implant with a superior articular surface shaped to articulate with the inferior articular surface.

  • Patent number: 8454585
    Abstract: An extender for use in an electro-mechanical surgical system that includes a surgical attachment that may be detachably coupled to an electro-mechanical driver device via a flexible shaft. The extender is a substantially rigid extender that includes a proximal end that may be detachably coupled to a distal end of the flexible shaft. The extender also includes a distal end that may be detachably coupled to the surgical attachment. The extender also includes at least one rotatable drive shaft configured to engage and be secured with a respective rotatable drive shaft of the flexible shaft such that rotation of the respective rotatable drive shaft of the flexible shaft by the electro-mechanical driver device causes the at least one rotatable drive shaft of the extender to rotate, thereby rotating a complementary connector of the surgical attachment so as to operate the surgical attachment.

  • Patent number: 8435302
    Abstract: An apparatus for distracting a disc space having an annulus. The apparatus includes a spinal implant having a pre-determined size sufficient to balance frictional fit in the disc space and elongation of the annulus. The implant has a top surface, a bottom surface, opposing lateral sides, and opposing anterior and posterior portions defining a substantially hollow center and a single vertical aperture. At least one of the opposing anterior and posterior portions presents a substantially flat impact face including an opening with an instrument retention feature. The apparatus also includes a rasp, a plurality of distractors, and an instrument able to engage and manipulate the spinal implant, the rasp, and the plurality of distractors. The size-specific rasp is adapted to clear the disc space of all soft tissue and cartilage. The plurality of distractors have progressively increasing heights adapted to distract the disc space before use of the spinal implant.

  • Patent number: 8343219
    Abstract: An intersomatic cage, an intervertebral prosthesis, an anchoring device and an instrument for implantation of the cage or the prosthesis and the anchoring device are provided. An intersomatic cage or an intervertebral prosthesis fit closely to the anchoring device, which includes a body of elongated shape on a longitudinal axis, of curved shape describing, along the longitudinal axis, an arc whose dimensions and radius of curvature are designed in such a manner that the anchoring device may be implanted in the vertebral plate of a vertebra by presenting its longitudinal axis substantially along the plane of the intervertebral space, where the anchoring device is inserted, by use of the instrument, through a slot located in at least one peripheral wall of the cage or on at least one plate of the intervertebral disc prosthesis to penetrate into at least one vertebral plate.

  • Publication number: 20120226282
    Abstract: A method of implanting a prosthetic component is disclosed that includes attaching a guide rod to the prosthetic component, removably coupling the guide rod to a shaft extending from a handle, and positioning the prosthetic component in an anatomical feature. The method also includes impacting an impaction portion of the handle and uncoupling the guide rod from the shaft, leaving the guide rod attached to the prosthetic component. The method further includes positioning a reamer over the guide rod to create a reamed opening in the anatomical feature.

    Abstract: Implant removal systems and methods for using the system for removing an implant from a bone are disclosed herein. In an embodiment, a method for removing an intramedullary implant from a bone includes navigating a guidewire into an intramedullary cavity of the bone; inserting the guidewire into a lumen of an intramedullary implant located in the intramedullary cavity of the bone; advancing a removal screw over the guidewire to the intramedullary implant; threading the removal screw into the lumen of the intramedullary implant to engage the removal screw to the intramedullary implant; and applying impaction force on the removal screw to remove the intramedullary implant from the intramedullary cavity.

  • Publication number: 20120089149
    Abstract: A known x-stop implantation instrument is modified to provide a slide hammer mechanism to selectively apply an impact force. Both the axial location of the slide hammer and the angle of the slide hammer may be adjusted. A surgeon, when necessary or desirable, may thus apply an impact force to the forward end of the implement having a least a component of force in the direction of insertion of the x-stop device. The invention permits the surgeon to vary both the position along the shaft where the impact is applied as well as the angle at which the impact is applied relative to the direction of insertion.

  • Publication number: 20120004664
    Abstract: Extraction instruments and systems for use in revision arthroplasty are provided. The extraction instruments are shaped and configured to fit within the typically tight confines in which revision arthroplasty is performed, and to enhance the surgeon's control over the axis, quantum and speed of the force that is required be applied to disrupt a bone-to-prosthesis bond. This enables completion of a revision arthroplasty to proceed more quickly, and with reduced risk that unwanted movements might cause accidental injury to nearby vital structures.

  • Patent number: 8080015
    Abstract: An impacting device for inserting, positioning and/or removing an implant and/or performing other impacting applications. The impacting device may have a head having at least one recess. The recess may have a insertion channel and a locking chamber. In one embodiment, the insertion channel and the locking chamber may be connected by an axial channel. The recess may pass through a lateral surface of the head so that the base surface may remain cohesive or unobstructed. A guide means, such as a guide rod, may be positioned though the recess so that the head may be moveable on the guide means and not disengage the guide means. A shaft having a handle may be attached to the head to assist a surgeon in moving the head on the guide means.

  • Patent number: 8070822
    Abstract: A method for controlling the mutual angle between the parts of an artificial hip joint during an operation for insertion of the artificial hip joint, is described. The stem of the femoral hip prosthesis is fastened permanently or removable in the usual manner in the proximal end of the femur. A tool for controlling of the mutual angle between the stem of the prosthesis and the cup of the prosthesis is fastened to the stem. The femur of the patient is then oriented in a predefined position and the cup is then brought into its intended position by means of the femur of the patient and the mentioned tool. A tool for controlling the mutual angle between the parts of the artificial hip joint is also described.
