Abstract
A spinal device (10) including a variable-length member (12) including a ratchet mechanism (14) that has an operative configuration that allows a change in length of the variable-length member (12) in one direction and prevents a change in length of the variable-length member (12) in an opposite direction, wherein the variable-length member (12) includes polyaxial-joint attachment members (32) for attachment to bone, which permit pivoting movement of the attachment members (32) about more than one pivoting axis, characterised by a force applicator (40) operative to adjust or advance the ratchet mechanism (14).
Description
- The present invention relates generally to spinal implants and prostheses, and particularly to spinal implants having ratchet mechanisms, such as a spinal implant with joints that permit movement in different degrees of freedom, or a spinal implant with a force applicator to control a ratchet mechanism.
- Scoliosis is a spinal deformity affecting many people. Current surgical treatment involves affixing long fusion rods to the spine by pedicle screws. The rod system is intended to force the deformed spine into a more healthy position. Other spinal disorders which are often treated by fusion include hyperkyphosis and hyperlordosis.
- As an alternative to fusion, PCT Patent Application PCT/US2011/035278 of the same inventor describes improved spinal devices that can be lengthened or shortened using a ratchet mechanism. The devices have a variable-length member that can be connected to standard pedicle screws as well as to other spinal rods, using appropriate connectors.
- The present invention seeks to provide further improved spinal devices.
- In one embodiment, the spinal device is in the form of a spinal rod (the term rod, or rod assembly, refers to one or more elongate components that together function as a rod and which do not necessarily have a cylindrical shape but can also be bars and other shapes) that can be lengthened or shortened using a ratchet mechanism. The rod is a variable-length member that can be connected to standard pedicle screws as well as to other spinal rods, using appropriate connectors. The variable-length member can also be directly connected to, or be supported by, bony elements of the spine.
- In one embodiment of the invention, the device can be set to three different configurations:
- a. Ratchet mechanism active and the variable-length member (rod) can change in length (extend or contract) in one direction.
- b. Ratchet mechanism not active and the variable-length member can move in opposite directions corresponding to the extending and contracting directions.
- c. Locked position, wherein the length of the variable-length member is fixed.
- In an embodiment of the invention, the selection of these configurations can be done by rotating an internal element of the assembly. For example, the rotation of the internal element can be done using a worm gear mechanism. The worm gear can be activated by a shaft, through a percutaneous procedure or by an implantable mechanism such as an electric motor, magnet arrangement or other means known to those skilled in the art.
- In another embodiment of the present invention, the variable-length member can have two portions with different rigidity. For example, the variable-length member can have a flexible portion (e.g., when the ratchet is built such that the rod can be only shortened) like a flexible cable, a rope, a flexible mechanical joint and other means known to those skilled in the art.
- In another embodiment of the invention, useful when the rod is supported directly by bone structure of the spine, the hook holding against the bone can have a second hook to fix it to the optimal position.
- The present invention will be understood and appreciated more fully from the following detailed description, taken in conjunction with the drawings in which:
-
FIG. 1 is a simplified pictorial illustration of a ratcheted spinal device, constructed and operative in accordance with a non-limiting embodiment of the invention; -
FIG. 2 is a simplified pictorial illustration of a ratchet mechanism of the ratcheted spinal device ofFIG. 1 ; -
FIG. 3 is a simplified illustration of a force applicator that can adjust or advance the ratchet mechanism of the ratcheted spinal device ofFIG. 1 ; -
FIG. 4 is a simplified pictorial illustration of a spinal device, including two rod assemblies that are connected between three vertebrae with three bone screws, constructed and operative in accordance with a non-limiting embodiment of the present invention, wherein there are connector assemblies that permit multiple degree-of-freedom movement; -
FIG. 5 is a simplified top view illustration of one preferred embodiment of the connector assembly, in accordance with an embodiment of the present invention; -
FIG. 6A is a simplified cross-sectional illustration of the embodiment ofFIG. 5 ; and -
FIG. 6B is a simplified cross-sectional illustration of a modified version of the embodiment ofFIG. 5 . - Reference is now made to
FIGS. 1-3 , which illustrates a ratchetedspinal device 10, constructed and operative in accordance with another non-limiting embodiment of the invention. - The ratcheted
spinal device 10 includes a variable-length member 12. In the illustrated embodiment, the variable-length member 12 is a rod. The term “rod” encompasses any slender element of any size and cross-sectional shape, such as but not limited to, a rod, bar, wire and the like. - As similarly described in PCT Patent Application PCT/US2011/035278,
spinal device 10 includes a ratchet mechanism 14 (FIG. 2 ), which has an operative configuration that allows a change in length of variable-length member 12 in one direction and prevents a change in length of the variable-length member 12 in an opposite direction.Ratchet mechanism 14 has ratchet teeth 16 (FIG. 3 ; also called ratchet rack 16) formed along an axial portion of variable-length member 12, and a pawl 18 (FIGS. 2-3 ) arranged to catch on one of theteeth 16.Pawl 18 extends from a controller element 20 (FIG. 2 ) mounted about a pivot 22 (FIG. 2 ) and provided with an eccentric cam 24 (FIGS. 2-3 ). Rotation ofeccentric cam 24 movespawl 18 to one of three positions: a) in ratchet engagement withteeth 16 so that variable-length member 12 can incrementally move in one direction, b) in locked engagement withteeth 16 so that variable-length member 12 cannot move at all, and c) moved out of engagement withteeth 16 so that variable-length member 12 can move in both directions freely. - As seen in
FIG. 1 , oneend 23 of variable-length member 12 is arranged to linearly move through anaperture 28 formed in ahousing 30. Variable-length member 12 includes two polyaxial-joint attachment members 32. Both polyaxial-joint attachment members 32 are used to attachdevice 10 to available bone structure of the spine. - In contradistinction to PCT Patent Application PCT/US2011/035278, in the present invention,
spinal device 10 includes aforce applicator 40 to controlratchet mechanism 14.Force applicator 40 includes, without limitation, acam 42 which has a tooth 44 (FIG. 3 ). Thehead 46 ofcam 42 is shown inFIG. 2 (e.g., hexagonal head);head 46 is not shown for simplicity inFIG. 3 . By turninghead 46 with a suitable tool, such as a wrench (not shown), in the clockwise direction ofFIG. 3 , thetooth 44 ofcam 42 forcefully moves ratchet rack 16 (upwards in the sense ofFIG. 3 ), so that the tooth in whichpawl 18 is engaged moves out of engagement withpawl 18 and the next lower tooth ofratchet rack 16 moves into engagement withpawl 18. Accordingly,force applicator 40 adjusts or advances theratchet mechanism 14. - Reference is now made to
FIG. 4 , which illustrates aspinal device 50, in accordance with an embodiment of the present invention. - In the illustrated embodiment,
spinal device 50 includes tworod assemblies 52 that are connected between threevertebrae 49 with threebone screws 54. Therod assemblies 52 may be constructed, without limitation, as ratchetedspinal devices 10 or other spinal devices. Connector assemblies 56 form jointed connections betweenrod assemblies 52.Connector assemblies 56 permit multiple degree-of-freedom movement of rod assemblies 52 (e.g., variable-length members 12), as will be explained below. - It is noted that any number of vertebrae can be selected, since the design of the system is modular. It is also noted that the middle jointed connection of the two
rod assemblies 52 does not have to be connected to any vertebra, meaning one or more vertebrae can be skipped, depending on the application. In the drawing figure,bone screws 54 are inserted in the pedicles, but other insertion locations can be used. - Reference is now made to
FIGS. 5 and 6A , which illustrate one preferred embodiment of theconnector assembly 56, in accordance with an embodiment of the present invention. -
Connector assembly 56 includes a bolt 58 (e.g., a central threaded bolt) having ahead 60, and which passes through a hole formed in afirst hinge member 62 and asecond hinge member 64, which may lie on top of, or be adjacent to, firsthinge member 62. Each hinge member is formed with a receiver 66 (FIG. 6A ) for receiving therein a pivot pin 68 (FIG. 5 ). One of the pivot pins 68 is pivotally received in anend 70 of one of therod assemblies 52, and theother pivot pin 68 is pivotally received in anend 72 of another of the rod assemblies 52 (FIG. 5 ). Thusadjacent rod assemblies 52 can pivot with respect to one another by means ofconnector assembly 56. A locking element 74 (such as a nut) securespins 68 in place (FIG. 6A ). Another locking element 76 (such as a nut) is threaded on the end of threadedbolt 58 to complete the assembly (FIG. 6A ). -
FIG. 6B illustrates a variation of the embodiment ofFIG. 6A . Like elements are designated by like numerals. The main differences are the shape of lockingelement 74 and thereceiver 66 of thefirst hinge member 62 has a closed aperture instead of the open aperture ofFIG. 6A . Other variations are also possible within the scope of the invention. -
Connector assemblies 56 permit multiple degree-of-freedom movement ofrod assemblies 52. Rotation is permissible about the longitudinal axis of central threadedbolt 58, and independently about the longitudinal axis of eachpin 68, which are perpendicular to the longitudinal axis of central threadedbolt 58.
