FIGS. 1-2 show anorthopedic device 100 that can be used for compression or distraction of bone parts according to an aspect of the present disclosure. Theorthopedic device 100 comprises anelongated body 110 havingfirst end 10 and asecond end 20. Afirst arm member 112 extends away from thefirst end 10 in a direction transverse to theelongated body 110 and terminates at anouter end 112 a. Thefirst arm member 112 can be integrally formed with thebody 110 or otherwise attached to thebody 110. Asecond arm member 111 transversely extends away from theelongated body 110 and terminates at anouter end 111 a. Thesecond arm member 111 is configured with abase portion 113 that is configured and adapted to movably engage theelongated body 110 allowing thesecond arm member 111 to be longitudinally movable along the elongated body. - According to one embodiment, the
elongated body 110 is provided withratchet teeth 110 a along its length for engaging with thebase portion 113. Thebase portion 113 is configured with ratcheting mechanisms that can selectably operate in compression or distraction mode. For example, thebase portion 113 can be configured with amode selector switch 117 that can be used to switch between the compression mode and the distraction mode. - The ratcheting mechanism is configured so that the
selector switch 117 not only changes the direction of the base portion's movement but also changes the locking direction of the device. This allows the desired compression or distraction to be maintained once it is reached. In the compression mode, thesecond arm member 111 is locked from moving in thedistraction direction 202 and can only move in thecompression direction 201. Conversely, in the distraction mode, thesecond arm member 111 is locked from moving in thecompression direction 201 and can only move in thedistraction direction 202. - The
base portion 113 also can be configured to have a neutral position for theselector switch 117 which will allow thesecond arm member 111 to freely move along theelongated body 110. Thesecond arm member 111 is moved by turning a turningkey handle 115 which is connected to ashaft 116 that actuates the internal mechanism of thebase portion 113. The internal structure of thebase portion 113, although not shown, is configured with a ratcheting mechanism utilizing a rack and pinion type gear arrangement or other suitable mechanisms known to one skilled in the art. - The
elongated body 110 is provided with an appropriate mechanism for stopping thebase portion 113 from sliding off thesecond end 20 of theelongated body 110. For example, in the embodiment shown inFIG. 1 , astop pin 119 provided near thesecond end 20 of the elongated body serves that function. - The
second arm member 111 extends from theelongated body 110 in the same direction as thefirst arm member 112. Theorthopedic device 100 also includes alocking sleeve 120 hingeably connected to theouter end second arm members hinge joint 121, wherein eachlocking sleeve 120 is configured for lockably receiving an elongated pin (not shown). - The
locking sleeve 120 comprises anelongated shaft 124 having an elongatedpin receiving bore 127 extending therethrough. Each of thehinge joints 121 hingeably connects onelocking sleeve 120 to the outer end of one of thearm members hinge joints 121 are coaxially aligned and represented inFIG. 1 by a hinge axis A. - According to an embodiment, the
hinge joints 121 can be configured and adapted to be normally locked in a position and prevented from pivoting about the hinge axis A by a spring-loadedlocking pin 112 b. When the spring-loadedlocking pin 112 b is pressed, thehinge joint 121 is unlocked and free to pivot about the hinge axis A. - Each of the
locking sleeves 120 is connected to thehinge joint 121 so that theelongated shaft 124 and thus the elongatedpin receiving bore 127 is oriented transverse to the hinge axis A. The transverse orientation refers to the fact that theelongated shaft 124 and the elongatedpin receiving bore 127 are at right angle to the hinge axis A. - According to an embodiment, the
locking sleeve 120 further comprises a threadedcollet 220 provided at one end of theelongated shaft 124 and acollet nut 122 that is threadably engaged to the threadedcollet 220 for locking an elongated pin that is received in the elongatedpin receiving bore 127. The threadedcollet 220 comprises a plurality ofcollet arms 221 defining one end of the elongatedpin receiving bore 127. Thecollet arms 221 are provided withscrew threads 227 integrally formed on their exterior surfaces whereby saidcollet nut 122 threadably engages the collets for locking the elongated pin received in the elongatedpin receiving bore 127. The integration of thescrew threads 227 into thecollet arms 221 allow for a low profile, compact design of thecollet 220. Thecollet arms 221 are defined by a plurality ofslots 222. -
FIGS. 3-5 show detailed structures of the threadedcollet 220 and thecollet nut 122. As shown in the longitudinal cross-section view of thecollet nut 122 inFIG. 5 , thecollet nut 122 is open at one end for receiving the threadedcollet 220 and has an interior surface provided withscrew threads 122 b for threadably engaging thescrew threads 227 of thecollet 220. At the end opposite from the threaded collet receiving end, a throughhole 122 a is provided for the elongated pin received in the elongatedpin receiving bore 127. The interior surface of thecollet nut 122 is configured with aconical surface 122 c. When thecollet nut 122 is fully threaded onto the threadedcollet 220, theconical surface 122 c contacts thecollet arms 221 and presses against the chamferedsurfaces 221 a of thecollet arms 221 and pushes thecollet arms 221 radially inwards. When an elongated pin is received in the elongatedpin receiving bore 127, the threading action of thecollet nut 122 causes thecollet arms 221 to move radially inward and clamp onto the elongated pin and lock the elongated pin in place. - According to an aspect of the present disclosure, the
screw threads 227 on the exterior surfaces of thecollet arms 221 are interrupted with a band of thread-free zone 228 dividing thescrew threads 227 into alower portion 227 a and anupper portion 227 b as shown inFIGS. 4 and 5 . Thecollet nut 122 is provided with one ormore detents 122 e protruding into the band of thread-free zone 228 and thus providing a mechanical interference with theupper portion 227 b of the screw threads that prevents thecollet nut 122 from being removed from the threaded engagement with thecollet 220. If one tries to remove thecollet nut 122, the one ormore detents 122 e and theupper portion 227 b of the screw threads would interfere with each other and prevent thecollet nut 122 from being removed. - In one embodiment, the one or
more detents 122 e are set screws and one or more setscrew receiving holes 122 d are provided on the side wall of thecollet nut 122. The setscrew receiving holes 122 d are threaded so that aset screw detents 122 e can be threaded therein. During assembly of the lockingsleeve 120, thecollet nut 122 is threaded onto thecollet 220 until the setscrew receiving holes 122 d align with the thread-free zone 228. Then theset screw detents 122 e are threaded into the receivingholes 122 d until thedetents 122 e protrude into the thread-free zone 228. InFIG. 4 , the sectioned view of one of thecollet nut 122 shows this arrangement. Thedetents 122 e can be provided in many other forms than set screws. For example, thedetents 122 e can be dowel pins of appropriate length that are either press fit, welded or secured in any suitable manner into receivingholes 122 d in thecollet nut 122. - Generally, it is envisioned that the user can lock an elongated pin received in the elongated receiving bore 127 by tightening the
collet nut 122 by hand. According to another aspect of the present disclosure, however, thecollet nut 122 can be configured and adapted to accommodate a driver tool for assisting the user in turning and tightening the collet nut. - In one example, the driver tool can be a
pin spanner wrench 300 shown inFIG. 6 and the collet nut is provided with one or more holes or recesses 122 f (seeFIGS. 1 , 4 and 5) along the outer surface of the collet nut for engaging thepin 310 of the driver tool.FIG. 7 shows another embodiment of thecollet nut 122 that is configured to be tightened using a cannulated driver tool (not shown) for locking/tightening thecollet nut 122. The hollow tubular opening of the cannulated driver tool would accommodate the elongated pin that is positioned in the elongated pin receiving bore 127 of the lockingsleeve 120. The throughhole 122 a of the collet nut can be configured in any variety of shapes as long as it is large enough to allow the elongated pin to pass through it. In this embodiment, the throughhole 122 a would be provided in a shape that matches the particular driving feature of the driver. For example, if the driver is a hex, square, or star driver, the throughhole 122 a would be appropriately shaped to engage the driving feature of the driver. In the example shown inFIG. 7 , the throughhole 122 a has a hexagon shape for accommodating a hex tip driver. - As described, the
orthopedic device 100 of the present disclosure is a universal device that can be used for compression or distraction of bone parts that are secured to the first andsecond arm members sleeves 120. Referring toFIG. 1 , after the bone parts are secured, the movablesecond arm member 111 can be moved incompression direction 201 ordistraction direction 202 by turning the turningkey handle 115. - Although the invention has been described in terms of exemplary embodiments, it is not limited thereto. Rather, the appended claims should be construed broadly, to include other variants and embodiments of the invention, which may be made by those skilled in the art without departing from the scope and range of equivalents of the invention. The scope of the invention disclosed herein is to be limited only by the following claims.
