    摘要: A percutaneous surgical system includes a plurality of tissue retractors configured to maintain a working space within soft tissue. The tissue retractors include a prong on their inner surfaces for engaging a ring member. The ring member maintains the position of the tissue retractors while also defining a number of channels inside the ring member. In one embodiment, the ring member includes concentric inner and outer walls connected by support walls. The inner wall defines an inner bore for supporting a working channel sleeve for the introduction of working instruments. A plurality of outer channels are defined between the inner, outer and support walls for the introduction of ancillary instruments to the surgical site. A manipulation tool is also provided that engages each tissue retractor for positioning the retractor within the patient.

In one aspect, an expandable template is provided having guides to guide a cutting device for bilateral formation of openings in the disc space. In another aspect, an improved guide member is provided for guiding a cutting tool. Still further, the invention provides an improved double barrel guide sleeve with a central distraction extension and lateral non-distracting extensions. Optionally, the guide sleeve includes windows and covers to selectively cover the windows. An improved reamer with an internal chamber and optional modular coupling is also provided. A depth stop is provided to selectively engage a tool shaft and a guide sleeve to control tool penetration into the disc space. A method of using the disclosed instruments is also provided.

    摘要: A template assembly is provided for marking locations on the disc annulus for the implantation of an interbody fusion device or the introduction of a working instrument. The template assembly includes a tubular body sized for percutaneous introduction into a patient and advancement to an affected intervertebral disc. An elongated shaft slidably extends through the tubular body and is threadedly engaged to the tubular body at its proximal end so that rotation of the shaft relative to the tubular body advances the shaft through the body. A guide foot is pivotably connected to the distal end of the tubular body to be pivoted from a first position aligned with the tubular body to a second deployed position oriented substantially perpendicular to the tubular body. The guide body is pivoted from the first position to the second position by advancement of the elongated shaft through the tubular body. The guide body in one embodiment defines a bore through which the working tip of an electrocautery instrument extends to mark the disc annulus. In another embodiment, the guide body itself defines an electrocautery projection. The template assembly can be anchored to the affected disc by a guide wire extending through the tubular body and about which the template assembly can be rotated to make an additional mark on the annulus at a predetermined distance from the first mark.

    摘要: A new top-loading transverse connector of the present invention for bridging between longitudinal members of a spinal fixation system implant. The transverse connector is loaded and clamped to the longitudinal member from the top permitting easy access and adjustment and may clamp at the same location along the rod as a vertebral fixation element. The transverse connector comprises an elongate body and an engagement portion on each opposing end of the elongate body. The engagement portion includes downward legs each with a surface to engage the longitudinal member. The downward legs are displaced from each other to define a space therebetween. The engagement portion includes an upper surface defining an opening therethrough. The opening intersects the space defined between the downward legs. Together, the space and opening are configured to receive the clamp assembly carried on the longitudinal member. Another object of the invention, is to provide an improved system including the transverse connector. Another object of the invention is to provide a transverse connector that clamps to the longitudinal member at a variable angle. Another object of the invention is to provide a separate engagement portion which can be used with existing transverse connectors to permit clamping at the same site as vertebral fixation elements. Another object of the invention is to provide a way to adjust the length of the elongate body of the transverse connector.
