Description
技术领域
本发明涉及类似克瑞森(Kerrison)的咬骨钳(Rongeur)系统，更具体地说，涉及已经被改进以包括动力推动的切割端部的类似Kerrison的咬骨钳系统(下文中称为PKS系统)。
背景技术
众所周知，在医疗技术中，Kerrison咬骨钳系统用于某些类型的需要切除靠近脊柱的骨头的脊柱手术中。例如，在椎板切除术过程中，或许需要修去一些更接近穿过脊柱管的神经的骨头，Kerrison咬骨钳系统包括一个伸长的剪刀型器具，该剪刀型器具包括一对彼此隔开并可相对另一个移动的小端部板，和将一个端部板相对另一个端部板移动的类似扳机的装置。通过操作扳机将板移动在一起的操作者施加的手动力咬合多骨结构，用于移去该多骨结构。显然，端部板相对较大以便于具有足够的强度以显示咬合操作。而且，端部板的形状，即位于器具最端部的那个部分需要钝化。端部(通常称为脚板)的形状和尺寸由必须产生的进行骨头咬合的强力决定，脚板必须产生一个相反的力，该力匹配相对其移动的另一端部板的力。与这个操作类似的是一对具有相对彼此移动的切割刀片的剪刀。显然，剪刀的尺寸由切割刀片上施加的阻力决定。施加到切割刀片的阻力越大，所需的剪刀越大。设计切割缝纫线的剪刀比设计切割纸板的剪刀更小，同样地，可以推测用于切割地砖的剪刀比用于切割纸板的剪刀大。而且，需要操作者施加的力在各种环境中不同，可以推测切割更硬的材料需要由操作者施加更大的力。
我们已经发现，我们可以避免需要用于切割或削尖骨头的手术操作中的力的要求，此前该手术操作由Kerrison咬骨钳或其它设计带有动力推动的操作的旋转切割器的骨头和组织咬合器具实现，该旋转切割器可相对安装脚板的一端移动或反之亦然，即将安装脚板的端部相对该旋转切割器移动。本发明的器具提供了许多超过此前已知的Kerrison咬骨钳系统的，在后面列出的优点。这些优点仅作为例子，并不看作是对本发明的范围的限定。
1)脚板和切割器更小并且工作端的外直径更小，允许医生到达在此前不能到达或不容易到达的病人的解剖区域；
2)脚板的导向边缘能够根据情况成形，使得它可以用于从骨头释放组织，提升了PKS系统的使用；
3)由于驱动切割器的马达吸收了大多数负载，大量减少了医生的工作；以及
4)通过使切割器相对脚板移动，医生增加了他的关于将切割器相对骨头定位的感觉，因此改善了医生的手上感觉。
在一个实施例中，本发明计划使用小齿轮和齿条系统以纵向移动驱动切割器的马达，并且明智地安装小齿轮，使得它同样起到用于使马达从PKS系统的主体进出的枢轴的功能。
发明内容
本发明的目的是提供一种改进的用于咬合病人的骨头和组织的Kerrison咬骨钳系统。
本发明的特征是在PKS系统中提供一个可相对脚板移动的由马达驱动的切割器。本发明的替换实施例是固定的马达/切割器和可移动的脚板。
用于将切割器相对脚板定位的PKS系统的本发明的另一特征是起移动互补的齿条作用的小齿轮同样起到将马达取下和插入PKS系统的作用。
本发明的另一特征是提供一种具有旋转切割器的PKS系统，该切割器设计成具有比此前已知的Kerrison咬骨钳系统小的整体外部直径。
本发明的另一特征是提供带有成形的脚板的动力推动的PKS系统，该脚板具有被设计成参与手术过程的导向边缘。
本发明的另一特征是提供一种减少需要医生施加的力和/或给医生提供增强感觉的动力推动的PKS系统。
通过下面的说明书和附图，本发明的前述和其它特征将更加清楚。

具体实施方式
本发明在其优选的实施例中使用了用于给切割器供电的气体驱动马达，本领域普通技术人员应当明白使用各种媒介的任何外科马达能够用于给切割器提供动力。此外，本发明被描述为使用MicroMax，Black Max和eMaxTM马达，这些马达可以从本专利申请的受让人那里获得，因此应当知道，可以为此替换其它种类的气动马达。除气动提供动力的马达外，本发明中可以使用由不同媒介提供动力的马达。可以说可使用任何能够插入并可操作本发明的PKS系统的马达，本发明的范围不限于优选的实施例中公开的马达。
说明书的这部分涉及相对于脚板定位马达/切割器的PKS系统的实施例，说明书的后面的部分将涉及相对于马达/切割器移动脚板的PKS系统的实施例。如图1所示，在图1中最清楚地示出了用于马达/切割器的直线运动的PKS系统，该附图1是通常由附图标记10表示的PKS系统的分解图，该系统包括马达12，头部套管14，切割器16，手枪形部件或枪18和脚板支撑器20。脚板支撑器是当组装时安装在头部套管14上的伸长的管状部件。在本实施例中的马达12是气动马达，头部套管14和切割器16是公知的，并可从受让人那里购买。为了容易操作，枪18成形为手枪形手柄，但是在本发明的范围内可以考虑其它形状，并应当在进行医疗手术过程时给医生良好的感觉。如下文详细描述的，扳机22可滑动地安装在枪18内，并直线地定位马达12。通过任何公知的夹具或连接机构将脚板支撑器20适合可拆卸地连接到枪18的端部。脚板24支撑在脚板支撑器20的端部，相对脚板支撑器20的轴向轴线有角度地设置，并延伸以和切割器16的端部定向成一直线。因此，在组装时，切割器16的钻头24与脚板24成直线，并且由于被连接到马达12，因此当扳机将马达直线地定位时，该钻头相对那里移动。根据本发明，脚板24能够被设计成适合需要不同尺寸和形状的脚板的手术过程。例如，相对脚板支撑20的轴向轴线的角度可以是30°，45°等。
PKS系统的组件如下，注意可以容易地拆卸和替换所有的子配件。头部套管14适合通过任何可购买的连接机构26连接到马达12的端部。切割器16的杆28滑入头部套管14，由轴承(未示出)支撑以进行旋转运动，并包括安装在马达12携带的可购买的夹具31中的连接端30。如上一段提到的，这些部件可以从本专利申请的受让人那里购买。
马达12，头部套管14和切割器16安装在穿过手柄18的主体32的轴向孔中，头部套管14穿过手柄18，从而穿过脚板支撑器20的中心通道滑过头部套管14，并且将钻头24邻近脚板22定位。手柄18(图3)包括用以接收扳机22的主体40的轴向通孔38，该通孔在主体32的底侧上延伸并且进入手柄18的手握部分42。如前所述，可以清楚马达安装在孔38的较宽部分44中，头部套管14的夹具部分26安装在孔38的较小直径部分46中，可移动扳机22安装在槽40中。图4和5示出了在组装好的情况下的PKS系统。
公开内容的下一部分描述了用于将马达直线地定位并将马达锁定在位的扳机的机构。如图2，4，6和6A所示，马达支撑机构50包括安装在轴向孔38的较宽直径部分44中的导向套管52，并且在一端上由卷簧54偏压，该卷簧在较宽直径部分44和邻近导向套管52的后端，并且当插入孔44时与前衬套60一起支撑马达。导向套管52的底部上携带的凸台57支撑将在下文中进一步详细描述的马达锁58。
如上所述，扳机22可滑动地安装在槽40中，并包括基本U形的部分或通道60，圆形手指口62，上部延伸部分64和限制槽66。带有向上的齿轮齿的齿条68安装在通道60中，由销70刚性地支撑在其中。小齿轮72由轴或销74可旋转地支撑，该轴或销安装通过在枪18的主体部分32中形成的正相反相对的孔76。为了便于旋转，衬套78安装在小尺寸72的中心孔80中。为了便于扳机22的移动，球82安装在通道60的底部上形成的槽中。互补齿条84支撑在马达锁58的底部表面上，其齿轮齿相反地与齿条68的齿轮齿相对。卷簧88夹在肩部90和通道部分60的后边缘92之间。与作用在将马达偏压到开始位置的导向套管52的端部的卷簧54共同作用将扳机22返回到开始位置(当切割头最远离脚板时)的卷簧88在PKS系统上提供平衡力，以确保操作者或医生在控制枪和定位切割器时具有良好的感觉。
如上所述，马达锁58起到将马达锁定在适当位置的作用，并被设计成当其插入到孔44中形成的制动器43时自动地锁定马达，当扳机在指定的位置时通过将马达锁58的端部压下释放马达。这保证了当医生进行手术过程时，马达将不会脱离接合。依照本发明，马达锁58通过直立的平行臂96和定位销98安装到凸台57。卷簧100安装在凸台57底部上形成的钻孔中，并在远离前端的枢轴的一端支撑靠在马达锁58的顶部表面102上。斜坡104安装在马达锁58的后端，并从后端的薄部分延伸到形成斜坡的厚部分，从而当马达插入并朝枪的前端向内移动时，马达壳上的凸缘或肩部45抬高斜坡的斜面，迫使马达锁58围绕小齿轮72枢轴转动，压缩弹簧100直到马达12的肩部45在马达锁58上的斜坡104的端部经过肩部106，落入在臂96和斜坡104前端的端部之间的凹槽或制动器110内。弹簧将迫使马达锁返回到将马达锁定在适当位置的初始位置。应当注意，依据本发明，马达锁58围绕小齿轮72旋转，即小齿轮72起齿轮和枢轴的双重作用。因此，当扳机收回时，也就是当其将切割器朝脚板放置并且止动销111在槽66的端部时，马达锁58不能绕枢轴旋转(参见图1)。能将马达拆去的唯一时间是当小齿轮72较靠近齿条84的前端，从而该齿条能够如图6所示围绕小齿轮72枢轴旋转时。
为了操作PKS系统，医生必须将脚板插入所需从病人身上去除骨头的位置，给钻孔马达提供动力以转动切割器，并握紧手柄以将切割器朝脚板定位。显然，医生不仅可以在切割器暴露到骨头时移动该PKS系统用于定位切割，如果需要的话，医生也可以滑动切割器以沿给定路径移动，并沿纵向路径切割骨头。
说明书接下来的部分涉及本发明的另一实施例，其中马达保持静止，相对切割器移动脚板。在该实施例中，如图7和8的举例，将类似图1所示的脚板支撑器的形状的脚板支撑器122连接的脚板120连接到扳机124，从而当扳机朝手柄126缩回时，脚板120将朝向切割器135的钻头128移动。手柄126的外部尺寸类似图1所示的手柄，并包括贯穿手柄126的主体部分132的通孔，该通孔在后端130包括直径较大部分128，朝前端131逐渐分段到直径较小部分137，在更前部分134直径重新增大。类似图1所示的马达的马达133安装在手柄126的后部，并且可在两个位置中移动的适合手指的锁定器136锁定和放开马达133。切割器以现有技术公开的通常的方式可拆卸地连接到马达。类似手枪手柄形状的手柄126包括从主体部分132向下延伸的手持部分140。围绕脚板支撑器122的是圆锥形的前端141，该前端包括邻近扳机124的前端安装在减小部分142的外径上的公知的连接端，其将脚板支撑器142锁定到扳机124。扳机124的前端包括向后延伸并限定一圆锥形孔150的环形端部148。这种形状保证了当将扳机收回时，脚板将具有足够的空间以允许钻头129移动其预期的距离，不会锁在马达133的夹具端部上。钻头129被连接到支撑在伸长管151中的切割器135。
通过在手柄126的手持部分140的前端中形成的孔158中安装的卷簧156将扳机124偏压到为最前位置的第一位置中。卷簧156靠着孔158的端面160和包括安装在扳机124的槽166中的突出物164的活塞162起作用。
在操作中，医生如握住手枪一样握住把手128，将手指插入可通孔170。通过握紧扳机124和手柄126，扳机机构将像描述的那样向后移动使脚板120更靠近钻头129，随着打开马达，允许医生进行所需除去病人的预定的骨头的过程。如图1示出的实施例的情况，医生能够将器具从局部目标横向移动，使得沿横向方向除去骨头。而且，由于PKS系统利用马达和钻头，并且不依靠强力除去骨头，可以将脚板设计成不同的形状和角度，使得适合进入其它不能使用这种步骤的身体区域中。
虽然已经通过详细的实施例示出和描述了本发明，应当理解和明白本领域普通技术人员可以在不脱离要求权利保护的本发明的精神和范围的条件下进行各种形式和细节的改变。
