Definitions
- the present invention relates to medical fixation devices having improved physical properties, more particularly, to biologically compatible fixation devices requiring torsional forces to secure their application within body tissue.
- fixation devices are used in different ways to assist in the reconstruction of damaged body tissue.
- a fixation device may be used to directly secure tissue in close approximation to neighboring tissue to effect healing such as is the case with meniscal fixation devices, or fracture fixation pins, screws, or wires.
- Other types of fixation devices are intended to provide mechanical stability and load sharing during the healing process, as when a graft is secured in a bone tunnel for ACL reconstruction.
- Fixation devices may also be used in conjunction with other device hardware such as plates, rods, or various other connecting members known in the art as part of an implant assembly, such as with a spinal screw fixing a plate to the vertebral body, spinal pedicle screws connected to posterior rod assemblies to name just a couple examples.
- Other fixation devices are used to anchor suture to bone so the suture can be used to secure injured soft tissues.
- Fixation devices typically have an elongate body, and one or more engaging feature(s) for retaining the device within body tissue or as part of a device assembly.
- the fixation device may either be inserted into body tissue directly, through a preformed hole with or without the aid of a tap, or as part of a device assembly within the bone cavity, such as with a screw/sheath assembly.
- fixation devices require the application of torsional forces from an insertion tool at one end of the implant to secure their application into body tissue, as with screw-type implants.
- Insertion tools are typically formed from an elongate shank having a mating feature formed on a distal end thereof for mating with a corresponding mating element formed on or in the head of the fixation device.
- One common type of driver tool includes a hexagonal-shaped or square-shaped socket for receiving a corresponding hexagonal-shaped or square-shaped head of a fixation device.
- Fixation devices were historically constructed of implantable metals and alloys which afforded sufficiently high tensile and torsional strength to withstand the rigors of insertion, but the implant remained in the body for prolonged periods of time.
- a drive head more resistant to deformation upon application of torsion may make a revision procedure easier, as there are some instances where torque driven devices need to be backed out and perhaps even reinserted. 5 Accordingly, there remains a need for fixation devices having improved physical properties, and in particular having a high failure torque and a high stripping strength.
- the present invention provides a fixation device including an elongate shank that includes proximal and distal ends and defines a longitudinal axis.
- the shank further includes formed thereon at least one engaging member for facilitating placement of the device in body tissue, and securing the device in the tissue once implanted.
- the fixation device also includes a drive head 5 having a proximal end, a distal end, and a radial cross-sectional geometry; where the distal end is mated to the proximal end of the elongate shank.
- the drive head includes at least one anti-rotational member having a longitudinal cross-sectional geometry integral with the drive head.
- the invention is also directed to fixation device installation kits containing the fixation device and a o drive tool, as well as methods for attachment of tissue. BRIEF DESCRIPTION OF THE DRAWINGS

- the present invention provides a fixation device including an elongate shank defining a longitudinal axis and having at least one engaging member formed therewith to engage body tissue and facilitate placement of the device within the tissue and to secure the device in the tissue once implanted.
- the fixation device also includes a drive head for applying torsion to the elongate shank having a proximal end and a distal end and which is mated to the elongate shank so as to transfer the torsion to the elongate shank, thereby providing for placement of the device in tissue.
- the drive head may have a circular or a substantially non-circular radial cross-sectional geometry, for example oval, and includes at least one anti-rotational member (ARM) formed integrally therewith to provide for increased transfer of the torsion to the shank.
- the fixation device comprises a drive head of circular or substantially non-circular radial cross-sectional geometry with at least one ARM integral therewith.
- the fixation device comprises a drive head of circular or substantially non-circular radial cross-sectional geometry with multiple ARMs located on either side of a plane of symmetry for ease of inserter application.
- the ARMs are of configuration and dimension effective to provide a mating fit with the driver tool in order to ensure efficient transfer of torsion from the drive head to the shank. The presence of the ARMs provides high failure torque and high stripping strength.
- a fixation device and installation kit including at least one fixation device and a cylindrical driver tool for cooperating with the fixation device.
- the fixation device has a shank with engaging member formed thereon and defining a longitudinal axis.
- a drive head is formed on the shank and has a circular or substantially non-circular radial cross-sectional geometry, such as oval, and at least one ARM formed integral therewith.
- the cylindrical driver tool has a distal end with a socket formed therein having a shape adapted to receive and engage the drive head of the fixation device.
- the ARM(s) also provide positive mating with the driver tool, such as a key in keyway configuration, to reduce driver slip-off, especially during off-angle insertions.
- the driver tool has an outer diameter that is equal to or less than an outer-most diameter of the fixation device.
- the present invention generally provides a fixation device 10, including elongate shank 12 defining longitudinal axis A and having at least one engaging member 20 formed thereon.
- engaging feature 20 is a helical thread.
- Drive head 30 has proximal end 32 and distal end 34 mated to elongate shank 12 at proximal end 14.
- drive head 30 has a substantially rectangular radial cross-sectional geometry, though drive head 30 could have substantially circular, rectangular, square, hexagonal, flattened oval or oval radial cross-sectional geometries, where the radial cross-section is defined as the cross-section perpendicular to longitudinal axis A.
- the configuration of drive head 30 includes at least one ARM 36 protruding from and integral with drive head 30 and extending from distal end 34 to proximal end 32 of drive head 30.
- the configuration of drive head 30 with ARM 36 is particularly advantageous in that it provides fixation device
- Elongate shank 12 of fixation device 10 can have a variety of configurations and can include a variety of different engaging members 20 formed thereon.
- Figures IA and IB illustrate an exemplary embodiment of fixation device 10 having shank 12 including core 18 with single helical thread 20 extending around core 18 from proximal end 14 to distal end 16 of shank 12.
- Thread 20 includes proximal and distal facing flanks 22, 24 that extend between base 26 and substantially flattened crest 28.
- Thread 20 defines a major diameter cb of shank 12, which can vary along the length of shank 12, although major diameter d 2 is substantially constant along a substantial portion of shank 12.
- Threads 20, however, can taper at the distal portion of shank 12 to terminate at apex 29 of shank 12.
- Core 18 of shank 12 defines a minor diameter di that can also be substantially constant or can vary along the length of shank 12. As shown in Figure IA, core 18 tapers from proximal end 14 to distal end 16. Once having the benefit of this disclosure, a person skilled in the art will appreciate that shank 12 shown in Figure IA is merely an exemplary embodiment of a shank 12, and that a variety of different shanks having different tissue-engaging members can be used with fixation device 10 in accordance with the present invention. Drive head 30 of fixation device 10 is shown in more detail in Figures
- Drive head 30 further includes length L h (shown in Figure IA) that extends between proximal and distal ends 32 and 34 thereof. Length L h of drive head 30 can vary, although length L h of drive head 30 may be optimized to allow the drive head to be received within a driver tool and to be driven into bone without shearing off. Drive head 30 has ARM 36 extending along length L h between distal end 34 and proximal end 32 of drive head 30.
- Figure 2 shows an alternate embodiment of drive head 40 of a fixation device according to the present invention.
- the radial cross-sectional geometry of drive head 40 is substantially square in shape with ARM 46 thereon that originates at distal end 44 and extends to proximal end 42.
- ARM 46 is tapered from proximal end 42 toward distal end 44.
- ARM 46 may be of other longitudinal cross-sectional geometries, e.g. parabolic, wedge, etc. without deviating from the scope of the invention, and that the ARM may extend only partially from distal end 44 toward proximal end 42 (not shown). Additionally, while not shown, ARM 46 may taper in the opposite orientation, i.e. from distal end 44 to proximal end 42.
- Figure 3 shows a further embodiment where drive head 50 contains four ARMs 56a, 56b, 56c and 56d positioned on opposing faces of drive head 50.
- a plurality of ARMs spaced equidistant around the drive head, such as depicted here, may be desirable from a procedural standpoint where the head possesses a plane of symmetry.
- the radial cross-sectional geometry of drive head 30 is square, and thus has two planes of symmetry. With ARMs on either side of a plane of symmetry, rotational alignment of a mating inserter with respect to the implant is further alleviated. Multiple ARMs may also afford further improved physical properties.
- Drive head 70 is substantially oval in radial cross-sectional shape defining a minor diameter Xi and a major diameter X 2 .
- Generally oval is known to include flattened ovals and ovals with flat portions perpendicular to the minor Xi or major X 2 diameters of drive head 70.
- minor diameter Xi of head 70 is about three-fourths the size of major diameter X2 of head 70, and major diameter X 2 of head 70 is equal to or less than minor diameter di of shank 62.
- Drive head 70 contains ARM 76 integral therewith.
- ARM 76 originates at distal end 74 of driver head 70 and extends towards proximal end 72 for a total length of L 1 -.
- the length L r is less than or equal to the length L h .
- FIG 5 shows another alternative embodiment of drive head 80.
- Drive head 80 is circular in radial cross-section and contains ARM 86 integral therewith.
- ARM 86 extends from distal end 84 towards proximal end 82.
- fixation devices can be driven into tissue using a driver tool, such as shown in Figures 6A-6B.
- Driver tool 90 can have a variety of shapes and sizes, but typically includes elongate shaft 92, having proximal handle portion 94 and distal end 98 having socket 96 formed therein and adapted to seat in mating relationship with the drive head of fixation devices of the present invention.
- socket 96 of driver tool 90 has an overall square shape and includes opposed ARM-engaging element 95 to engage and cooperate with ARM 116 once drive head 110 of fixation device 100 is placed in cooperation with socket 96 of drive tool 90.
- ARM-engaging elements 95 form a close fit with drive head 100 and cooperate with ARM 116 in such a way as to provide the mated relationship of drive head 110 within socket 96.
- the size and configuration of the socket 96 in relationship to drive head 110 and ARM 116 should be sufficient to provide a secure fit between drive head 110 and driver tool 90, and to prevent rotation of driver tool 90 with respect to fixation device 100.
- Driver tool 90 can also contain an inner lumen (not shown) extending there through for receiving free ends of suture.
