    摘要： A handheld medical instrument designed for efficient, atraumatic blunt tissue dissection and/or elevation during surgery. The instrument generally comprises an elongated shaft having a cottonoid or similar disposable dissection device at one or both ends. Attachment to the cottonoid may be direct or the shaft may include grasping constructs designed to grasp the cottonoid or to grasp a support structure which is attached to the dissection device. The devices may have reusable components or may be disposable.

    摘要： An interbody fusion device includes a base member, a top member, and an expansion mechanism for moving the top member relative to the base member. The expansion mechanism may include a connector drive rod assembly, a gear, a threaded rod, and a support means. The gear ring is coupled to the threaded rod and is rotatable. The expansion mechanism may also include at least one load head coupled to the threaded rod. An alternative interbody fusion device is also disclosed and includes a bottom member, a superior member, and an expansion mechanism for moving the superior member relative to the base member, wherein the expansion mechanism comprises at least one expansion assembly for moving an end of the superior member relative to the bottom member.

    摘要： An interbody fusion device including a body member, at least one side member engaging the body member, and at least one movement mechanism that engages at least one side member and the body member. A surgical method for maintaining a space between two vertebral bodies in a spine, including the steps of obtaining a medical device, such as an interbody fusion device, and inserting and coupling an expansion tool into an opening within the medical device. The surgical method also including slidingly inserting the medical device into a space between two vertebral bodies and rotating the expansion tool to move the at least one side member in a direction relative to the body member. The method may further include detaching the expansion tool from the medical device and removing the tool from the space between the two vertebral bodies in the spine.

    摘要： An interbody fusion device includes a top member, a base member, and an expansion member. The top member includes a first bone-engaging side and a threaded opening. The base member is received by the top member and includes a second bone-engaging side and an open cavity aligned with the threaded opening of the top member. The expansion member is disposed within the open cavity for rotation about an axis. The expansion member includes a threaded portion threadably engaged with the threaded opening. Rotation of the expansion member translates the first bone-engaging side away from the second bone-engaging side along the axis.

    摘要： Variable height intervertebral devices and method of employing the devices are disclosed. The devices and methods can maintain or re-establishing anatomic spacing along a spine and can ensure avoidance of long-term structural, neurological, vascular, and/or other systemic impairments. The intervertebral device includes a cylindrical body having a first end and a second end opposite the first end; a first disk threaded to the first end of the cylindrical body and a second disk mounted to the second end of the cylindrical body; means for rotating the cylindrical body whereby the first disk translates along the cylindrical body to vary the height of the device; and a plurality of pins mounted to one disk, the plurality of pins slidably engageable with a plurality of sleeves mounted to the other disk, the pins and sleeves inhibiting the first disk from rotating when the cylindrical body is rotated.
