Description

手动式骨内器械
本发明是针对基于2005年1月25日提出的、名称为“手动式骨内器械”的发明专利申请No.200580003261.8(PCT/US2005/002484)提出过的分案申请(分案提交日2009年5月5日、申请号200910138130.0)再次提出的分案申请。
相关申请
本申请要求于2004年1月26日递交的、名称为“手动式骨内器械”的No.60/539171临时专利申请的优先权。
本申请要求于2004年2月26日递交的、名称为“冲击驱动式骨内针”的No.60/547868临时专利申请的优先权。
技术领域
本发明总体上涉及一种用于进入骨髓的医疗器械,更具体地是涉及一种用于穿透骨头并且将穿透器或者针插入到相关的骨髓内的器械和方法。
背景技术
每年,在美国有数百万的患者因为威胁生命的紧急情况而接受治疗。这种紧急情况包括休克、外伤、心脏病、药物过量、糖尿病酮酸中毒、心律失常、烧伤以及癫痫,这里仅仅列举了一些。例如,根据美国心脏协会的统计,每年超过1,500,000的患者受到心脏病的威胁(心肌梗塞),他们中超过500,000人死于致命的并发症。
处理所有这些紧急情况的关键因素就在于快速确立静脉(IV)注射管,以将药物和流体直接注入到血液循环系统内。无论是在急救车内由护理人员救治,还是在急救室内由应急专家救治,其目标都是相同的——启动静脉注射以将挽救生命的药物和流体注入。在实施进入血管的过程中,成功地处理这些危重紧急情况的能力极大程度地取决操作者的技能和运气。尽管对某些患者启动静脉注射相对容易,但在对大约20%的患者建立静脉进入时,医生、护士和护理人员经常经历极大的困难。在尝试解决此问题时,反复地采用锋利的针刺这些患者,并且可能会需要侵入性的过程以最终建立静脉进入。
在实现进入静脉时另一复杂因素发生在“现场”中,例如,在事故现场或者在救护车的运输途中,这时难于找到目标,并且过分的运动使得进入静脉系统非常困难。
在患者患有慢性疾病或者年纪较大的情况下,根本找不到容易进入的静脉。由于周围静脉的解剖性缺乏、肥胖、极度脱水或者之前采用过IV药物,其他患者可能没有可用的IV位置。对于这些患者,找到用于注入挽救生命的药物的适当位置变成了意义重大而又令人沮丧的任务。在发病率和死亡率统计通常不能得到时,已知的是,由于挽救生命的IV疗法进入血管系统被延迟或者只是不可能,而使许多遭遇威胁生命的紧急情况的患者死于并发症。对于这些患者,需要找到可替代的方法。
例如为注射器、皮下注射器针头、导管、IV管和旋塞的许多医疗装置可包括销式(外螺纹)或者套筒式(内螺纹)路厄式适配件。销的端部或者套筒的端部可包括螺纹,这些螺纹允许相关的医疗器械可拆卸地与其它设备接合,其中所述其它设备具有互补的路厄式适配件。路厄式接头在某些时候被称作路厄式滑套(slip)或者路厄式锁。路厄式滑套需要相关的卡箍拧半圈,从而使销的端部和套筒的端部彼此牢固接合。当被接合并且被拧半圈或者更多圈时,路厄式锁通过在销和套筒之间形成水密式配合而发挥作用。路厄式锁通常包括位于套筒端部上的螺纹锁定卡箍,其中所述卡箍与相关的销端部的耳部或者突出部匹配,从而提供了更为主动的锁定连接。路厄式接头通常形成流体紧密封。一些路厄式接头可包括锥形适配件。
发明内容

具体实施方式
通过参照附图1A-7,可最好地理解本发明的一些优选实施例和它的优点,其中在所述附图中相同的附图标记表示相同和类似的部件。
就治疗人类患者来描述本发明的各个方面。然而,包含本发明教导的器械和方法还可用于治疗动物。
有时候,电池动力的驱动器不能有效地用于或不适用于骨内(IO)进入。这些情况可能涉及军事的特殊行动,因为极端的温度和严格的重量限制限制了在战斗中的可携带物。对于民用紧急医疗服务(EMS)或者第一响应者而言也是一样,因为长时间的存储并且又很少使用使得电池动力的驱动器的方便性不切实际。为此,手动驱动器提供了优于电池动力驱动器的一些优点。有时采用手动驱动器实施骨内进入比采用动力驱动器所需的时间长。但是,采用任一种驱动器都可以将骨头穿透并且进入到相关的骨髓。当使用手动驱动器时,可将人力施加到手柄或者把手上,从而将穿透器或者针插入到骨头内以进入到骨髓。在电池动力驱动器不能执行其功能时,例如由于电源枯竭的情况下,手动驱动器还可用作有用的备用件。
图1A、1B和1C示出了手动驱动器10a的一个实施例,其中手柄12a包括驱动轴16a。手动驱动器10a还可包括如图3A所示的可选择的棘轮机构。手柄12a可被成形为多种形状,例如可形成为具有手指握部20。手柄12a可采用适用于多次使用的材料或者适用于一次性或者可抛弃性使用的材料制成。还可以采用T形手柄12e(参见图3c)、大致为圆形或者卵形手柄12a(参见图1A和1B)、手枪握把式手柄12b(参见图2)或者其它任何在手动插入穿透器时适于人手或手指握持的符合人体工程学设计的形状。
根据本发明的教导,多种技术都可适用于可拆卸地将手柄接合或者连接到相关的接头和/或穿透器上。对于一些应用场合而言,手柄和相关的接头可形成为一个单独的单元。参见图6A和6B。在这种构造中,手柄/接头的组合件可操作地连接到组织穿透器的针座上。手柄和接头可以或者不可以彼此拆开。对于其它一些应用场合而言,手柄可以在不使用接头的情况下可拆卸地与针座和相关的穿透器接合。
图1B示出了部件之间分离的器械10a。手柄12a包括可选择的手指握部或者手指座20。驱动轴或者连接件16a可拆卸地与接头180的端部181接合。内穿透器或者套管针220从接头180的端部182处延伸。接头180和相连的内穿透器220彼此通过路厄式适配件、螺纹式连接或者形成于针座200的第一端201上的其它适当的适配件可拆卸地连接。外穿透器210从针座200的第二端202延伸。
图1C示出了器械10a的端部视图。
图1D中的开口186可形成在第一端181内以接收相关的驱动轴16a。参见图1D。开口186可形成为各种构造和/或尺寸。对于一些应用场合而言,开口186可包括其尺寸适于容纳驱动轴16a部分的通道或通路。一块或多块腹板136可形成在端部181内并从开口186处延伸。开放部分或者空间138可形成在腹板136之间。各个从手柄12a的相邻部分延伸的凸起146可拆卸地与腹板136和空间138接合。开口186和相关的腹板136可用于将接头180与手动驱动器或者动力驱动器可拆卸地连接。图5B示出了动力驱动器的一个例子。
图1E示出了穿透器组件160的放大视图。
如图1F所示,穿透器组件160可包括接头180、针座和相关的针座200、外穿透器210和内穿透器220。穿透器组件160可包括外穿透器(例如套管、中空管或者中空钻头)以及内穿透器(例如管心针或者套管针)。各种管心针和/或套管针都可以设置在外穿透器内。对于一些应用场合而言,外穿透器或者套管210可被描述为基本上细长的管,其尺寸适于把内穿透器或者管心针220接纳于其中。内穿透器220的部分可设置在延伸穿过外穿透器210的纵向通道184内。内穿透器220的外径和纵向通道184的内径可被选择,以便内穿透器220可在外穿透器210内可滑动地布置。
金属盘70可被设置于开口186内,用于可拆卸地将接头180和磁性驱动轴连接。对于一些应用场合而言,驱动轴16a可被磁化。内穿透器220的端部223优选地与金属盘70相间隔,其间设置有绝缘或者非导电性材料。
外穿透器210的尖端211和/或内穿透器220的尖端222可被操作以穿透骨头和相关的骨髓。尖端211和/或222的构造可被选择为以产生的外伤最小的方式穿透骨头或者其它体腔。内穿透器220的第一端或者尖端222可呈梯形,并可包括一个或多个切割表面。在一个实施例中,外穿透器210和内穿透器220可在相关的制造过程中作为一个单元被一起磨削。提供匹配的配合允许各尖端211和222作为一个单独的钻孔单元,当将穿透器组件160的部分插入到骨头和相关的骨髓内时,该单独的钻孔单元有助于插入并且使伤害最小。内穿透器220还可包括纵向凹槽(未明确示出),该纵向凹槽沿着内穿透器220的侧部延伸,从而当穿透器组件160更深地钻入到相关的骨头内时,允许骨头屑和/或组织从插入处排出。外穿透器210可采用不锈钢、钛或者其它具有适当强度和耐用性的材料制成,以穿透骨头。
针座200可用于在相关的穿透器在所选择的插入位置处插入到患者的皮肤、软组织和相邻骨头时稳定穿透器组件160。针座200的第一端201可操作,以用于与相关的接头180可拆卸地接合或连接。针座200的第二端202的尺寸和构造可与外穿透器210相关的插入位置相适。针座200与外穿透器210的组合有时可被称作为“穿透器装置”或者骨内针。
对于一些应用场合而言,接头180可被描述成基本上为圆筒形的管,它部分地由第一端181和第二端182所限定。接头180的外部可包括与端部181相邻的扩大锥形部。若干纵向凸脊190可形成在接头180的外部上,以在与驱动轴相连时允许操作者抓紧相关的穿透器组件160。参见图1E。当外穿透器210已经插入到骨头和相关的骨髓内时,纵向凸脊190还允许接头180被抓紧,以使其与针座200分开。
接头180的第二端182可包括开口185,此开口185的尺寸适于将针座200的第一端201接收于其内。螺纹188可形成于与接头180的第二端182相邻的开口185内。螺纹适配件188可用于使接头180与和针座200的第一端201相邻的螺纹适配件208可拆卸地连接。

对于一些应用场合而言,针座200的端部202可具有法兰状的大致构造。尺寸适于容纳保护盖或者针帽234一端的角状狭槽或凹槽204可形成于端部202内。狭槽或凹槽204可用于使盖234与穿透器组件160可拆卸地接合。参见图1A、1E和2。对于一些应用场合而言,盖234可被描述为具有圆形端部232的大致为中空的管。盖234可被设置于相关的狭槽204内,以在与相关手柄相连之前保护外穿透器210的部分和内穿透器220的部分。盖234可包括形成于其外部上的若干纵向凸脊236。纵向凸脊236彼此配合,以允许在不污染相关的穿透器部分的情况下将盖或针帽234安装和拆卸。盖234可由各种塑料和/或金属制成。
针座200的第二端202的尺寸和构造可被改变,以适应各种插入部位和/或患者。针座200可令人满意地与多种法兰或者其它适于接触患者皮肤的构造一同使用。同样,端部202和相关的法兰可与各种针座一同使用。本发明不限于针座200、端部202或者相关的法兰。
通道206可从第一端201延伸通过第二端202。通道206的内径可被选择为牢牢地与穿透器210的外径接合。通道206的尺寸和构造可被选择为保持相关的穿透器组件与针座200相接合。
图1G示出了形成在被设置于外穿透器210内的内穿透器220端部上的尖端222的放大视图。图1H示出了形成于外穿透器210端部上的尖端211的放大视图。
在本发明的一个实施例中,穿透到骨髓中的步骤可包括:转动或者旋转驱动轴,以通过旋转运动将穿透器24(参见图4A)、穿透器110(参见图4B)或者穿透器210(参见图1A-1B)插入到骨头和相关的骨髓内,将相关的驱动轴从接头80或180上脱离开并且将接头80或180从相关的针座100或200上脱离开,让针座100或200以及相连的穿透器24、穿透器110或穿透器210位于骨髓内。穿透到骨和相关骨髓内的深度可由针座100的第二端102和尖端30或者尖端111的极限端之间的距离或者针座200的第二端202和尖端211的极限端之间的距离来决定。对于一些应用场合而言,螺纹连接或者适配件108或208允许与各种类型的路厄式锁和/或路厄式适配件相连,其中与静脉注射管或者注射器相关的所述路厄式锁和/或路厄式适配件与带有针座100的第一端101或者针座200的第一端201相连。
