所谓CoreLockTM技术，申请人指的是'031专利中公开的任何伸缩式夹具、固定装置、锁定装置和/或压紧装置，例如固定装置200(参见例如图16)，固定装置700(参见例如图25-26)和固定装置900(参见例如图34-35)和锁定装置1030(参见例如图44-44A)和压紧装置1024(参见例如图45-45A)。
By CoreLock™ Technology, Applicant is referring to any of the telescopic clamps, securing devices, locking devices, and/or compression devices disclosed in the '031 Patent, for example securing devices 200 (see e.g., FIG. 16 ), 700 (see e.g., FIGS. 25-26 ), and 900 (see e.g., FIGS. 34-35 ) and locking device 1030 (see e.g., FIGS. 44-44A ) and compression device 1024 (see e.g., FIGS. 45-45A ).
应当理解，'031专利中的上述固定、锁定和压紧装置可以以本领域技术人员将会理解的方式以各种组合的形式与植入物10一起使用。
It is to be understood that the aforementioned securing, locking, and compression devices of the '031 Patent can be used with implant 10 in ways that would be appreciated by a person of skill in the art, in varying combinations.
因此，植入物10可具有使其适合与这种固定、锁定和压紧装置一起使用的特性。
Thus, implant 10 can have characteristics that make it suitable for use with such securing, locking, and compression devices.
例如，孔32的一部分(例如近侧孔部分36)可以如参考'031专利的图47A-47B及其他区域所描述的那样是带键的。
For example, a portion of bore 32—e.g., proximal bore part 36—can be keyed as is described with reference to, amongst other areas, FIGS. 47A-47B of the '031 Patent.
如'031专利中所陈述的那样，例如参考锁定装置1030和压紧装置1024，IM植入物1002的纵向孔1006的一部分可以如在1020、1022处那样带键，以便与锁定装置1030的第二部件1078和/或压紧装置1024的第二部件1076键槽配合在一起。
As set forth in the '031 Patent, for example with reference to locking device 1030 and compression device 1024, a portion of longitudinal bore 1006 of IM implant 1002 can be keyed as at 1020, 1022 so as to key with second component 1078 of locking device 1030 and/or second component 1076 of compression device 1024.
这产生了如下情况，其中锁定和压紧装置1030、1024的第一部件1050、1046可相对于第二部件1078、1076旋转，并且借助于第一部件1050、1046和IM纵向孔1006之间的螺纹式相互作用，锁定和压紧装置1030、1024可相对于IM植入物纵向移动。
This creates a situation in which first components 1050, 1046 of the locking and compression devices 1030, 1024 can be rotated relative to second components 1078, 1076 and, by virtue of the threaded interaction between first components 1050, 1046 and the IM longitudinal bore 1006, locking and compression devices 1030, 1024 can be moved longitudinally relative to the IM implant.
这种移动可以使与相应的固定、压紧或锁定装置相关联的螺钉分别在IM植入物的狭槽内沿着特定方向压紧、固定或锁定。
Such movement can cause screws associated with the respective securing, compression, or locking device to be secured, compressed in a particular direction within a slot of the IM implant, or locked, respectively.
如下面更详细描述的那样，申请人预期这种机构在此处可以用于锁定开口22、26、30和狭槽24、28内的螺钉53-57中的任何螺钉和/或致使开口22、26、30和狭槽24、28内的螺钉53-57中的任何螺钉平移。
As described in more detail below, Applicant contemplates that such mechanisms can be used herein to lock and/or cause translation of any of screws 53- 57 within openings 22, 26, 30 and slots 24, 28.
来自'031专利的某些示例虽然为了简单起见而可以使用，但是应该理解，'031专利中的任何固定、锁定和/或压紧装置都可以与本文所描述的植入物10和仪器一起使用。
Certain examples from the '031 Patent might be used for simplicity's sake, but it is to be understood that any of the securing, locking, and/or compression devices of the '031 Patent can be used with implant 10 and the instrumentation described herein.
还应注意，锁定和压紧装置1030、1024的第一部件1050、1046可进一步包括大致相似的特征，并且还在2007年1月26日提交的编号8,303,590的美国专利(“'590专利”)中被详细描述，上述专利的公开内容在此通过引用并入本文中。
It should also be noted that first components 1050, 1046 of locking and compression devices 1030, 1024 can further include generally similar features, and are also described in detail in U.S. Pat. No. 8,303,590 (“'590 Patent”), filed Jan. 26, 2007, the disclosure of which is hereby incorporated by reference herein.
目前，'031专利中的上述固定、锁定和/或压紧装置的使用将被搁置，但是将在下面的公开中重新考虑。
The use of the aforementioned securing, locking, and/or compression devices of the '031 Patent will, for the moment, be set aside but revisited in the disclosure below.
转到图1和图2A-C，其中示出了夹具凸头60。
Turning to FIGS. 1 and 2A -C, a jig nose 60 is illustrated therein.
如图1所示，夹具凸头60可经由夹具凸头60的轴部62的远侧部分上的一个或多个凸起64附接到植入物10上。
Jig nose 60 can be attachable to implant 10, as shown in FIG. 1, via one or more protrusions 64 on a distal section of a shaft 62 of jig nose 60.
备选地，可使用一个或多个凹槽来代替凸起。
Alternatively, one or more recesses can be used instead of protrusions.
夹具凸头60可具有主体70，其中轴部62从主体70延伸。
Jig nose 60 can have a body 70 with shaft 62 extending from body 70.
轴部62可具有螺纹部分66和基本平坦的部分68。
Shaft 62 can have threaded sections 66 and substantially-flat sections 68.
在一个示例中，轴部62上可包括两个至四个或更多个螺纹部分66以及两个到四个或更多个基本上平坦的部分68。
In an example, two to four or more threaded sections 66 can be included on shaft 62, as well as two to four or more substantially-flat sections 68.
螺纹部分66可以沿着轴部62的横截面的方向弯曲，以使得螺纹部分66可以共同地限定略微圆柱形的螺纹形状。
Threaded sections 66 can be curved along a cross-sectional direction of shaft 62 so that, collectively, threaded sections 66 can define a somewhat cylindrically-threaded shape.
如下所述，这使得轴部62可以与外部安装的压紧螺母(类似于'031专利的压紧螺母1124)的螺纹部分相互作用。
As described below, this is so that shall 62 can interact with a threaded portion of an externally-mounted compression nut, similar to compression nut 1124 of the '031 Patent.
因此，尽管夹具凸头60可以构造用于如下所述的内部压紧，但是，如果需要的话(例如，为了增强内部压紧力)，夹具凸头60也可以与外部安装的压紧仪器、例如'031专利的压紧螺母1124一起使用。
Thus, although jig nose 60 can be configured for internal compression as described below, jig nose 60 can also be used with externally-mounted compression instruments, such as compression nut 1124 of the '031 Patent, if needed (e.g., to augment internal compression).
夹具凸头60还可以包括穿过主体70和轴部62的内腔72以及处于主体70的近侧部分中的开口或切口74。
Jig nose 60 can also include a lumen 72 through body 70 and shaft 62, and openings or cutouts 74 in a proximal section of body 70.
在一个示例中，切口74可以延伸穿过主体70并且通向内腔72，或者切口74可以仅仅在一定程度上(部分地)延伸通过主体70。
Cutouts 74 can extend through body 70 and open into lumen 72, in an example, or cutouts 74 can extend only partway through body 70.
在切口74仅仅在一定程度上(部分地)延伸通过主体70的情况下，切口74可以限定将内腔72与切口74分开的底层表面。
In the latter case, cutouts 74 can define a floor surface that separates lumen 72 from cutouts 74.
在一个示例中，可以设置两个切口74，它们由主体70的实体部分76分开。
In an example, two cutouts 74 can be provided, which are separated by a solid section 76 of body 70.
切口74可由第一和第二凸缘75、77限定，如下面将更全面地描述的那样，第一和第二凸缘75、77以等于或略微大于马蹄形件150的臂154的厚度的距离分开。
Cutouts 74 can be defined by first and second flanges 75, 77 that are separated by a distance that is equal to or slightly greater than a thickness of arms 154 of horseshoe 150, described more fully below.
夹具凸头60的近侧面还可包括一个或多个凹槽78，并且例如图2B中示出了两个凹槽78。
A proximal face of jig nose 60 can also include one or more recesses 78, and by way of example two recesses 78 are shown in FIG. 2B.
图3是压紧仪器90的压紧螺母100的立体图。
FIG. 3 is a perspective view of a compression nut 100 of compression instrument 90.
压紧螺母90可具有轴部102和主体104。
Compression nut 90 can have a shaft 102 and a body 104.
在一个示例中，轴部102可具有成形为与驱动工具的匹配部分(例如，T形手柄或直手柄的凹形部分或窝座)相接合的部分(截面)。
Shaft 102, in an example, can have a section shaped to engage with a mating portion of a driving tool, such as a female portion or socket of a T-handle or a straight handle.
因此，压紧螺母100可以被驱动工具(未示出)旋转，该驱动工具非旋转地(不可相对旋转地)接合轴部102。
Thus, compression nut 100 can be rotated by a driving tool (not shown) that non-rotationally engages shaft 102.
压紧螺母100的主体104的一部分还可以是多边形的，在一示例中是六边形的。
A portion of body 104 of compression nut 100 can also be polygonal-shaped, in an example hexagonally shaped.
外凸缘106可以从主体104延伸，并且紧邻外凸缘106的可以是凸起108，在一个示例中，凸起108可以是圆柱形的。
An outer flange 106 can extend from body 104, and next to outer flange 106 can be a projection 108 that can be, in an example, cylindrically shaped.
沟槽110可以围绕凸起108的圆周的一部分或全部延伸到凸起108中。
A groove 110 can extend into projection 108 about part or all of its circumference.
此外，压紧螺母100可具有带内螺纹的中空螺纹孔112。
Further, compression nut 100 can have a hollow threaded bore 112 that is internally threaded.
参考图1和图4，其中示出了压紧仪器90的压紧柱120。
Referring to FIGS. 1 and 4, a compression post 120 of compression instrument 90 is shown.
压紧柱120可包括轴部122和螺纹主体121，所述螺纹主体121可接收在压紧螺母100的螺纹孔112中。
Compression post 120 can include a shaft 122 and a threaded body 121 that can be received in threaded bore 112 of compression nut 100.
主体121可具有围绕其圆周布置的螺纹部分126和基本上平坦的部分128。
Body 121 can have threaded sections 126 and substantially flat sections 128 arranged about its circumference.
在一个示例中，可以围绕主体121的圆周限定四个弯曲或平螺纹部分126，所述四个弯曲或平螺纹部分126共同限定略微圆柱形的螺纹形状。
In an example, four curved or flat threaded sections 126 can be defined around body 121's circumference that, collectively, define a somewhat cylindrically-threaded shape.
在直径上相反的螺纹部分126之间的距离可以大约等于压紧螺母100的中空螺纹孔112的内径。
A distance between diametrically-opposite threaded sections 126 can be approximately equal to the inner diameter of hollow threaded bore 112 of compression nut 100.
在主体121上可以包括更多或更少的螺纹部分126。
More or fewer threaded sections 126 can be included on body 121.
同样，在一个示例中，在主体121上可以包括四个基本上平坦的部分128。
Likewise, in an example, four substantially flat sections 128 can be included on body 121.
平坦部分128可以共同地限定多边形形状，在一个示例中限定略微正方形或矩形的形状。
Flat sections 128 can collectively define a polygonal-shape, in an example a somewhat square or rectangular shape.
在直径上相反的平坦部分128之间的距离可以大约等于以下描述的防旋转框架130的孔146的直径。
A distance between diametrically-opposite flat sections 128 can be approximately equal to the diameter of bore 146 of anti-rotation frame 130, discussed below.
在主体121上可以包括更多或更少的平坦部分128。
More or fewer flat sections 128 can be included on body 121.
压紧柱120的轴部122的远侧端部还可以例如在124处弯曲或以其他方式成形，以使得远侧端部124可以与骨螺钉的轴部接合以实现压紧目的。
A distal end of shaft 122 of compression post 120 can also be curved as at 124 or otherwise shaped so that distal end 124 can engage with the shaft of a bone screw for compression purposes.
