现在特别参考图4至图10,套管针组件100的套管针机构130被配置成相对于套管针组件100的壳体组件110纵向移动。套管针机构130包括:管状构件132,该管状构件可滑动地设置在壳体组件110内;套管针构件134,该套管针构件从管状构件132内向远侧延伸;以及铰接机构140,该铰接机构可操作地设置在管状构件132内并被配置成允许使套管针构件134相对于管状构件132选择性地铰接。
套管针机构130的管状构件132包括近侧区段132a和远侧区段132b。近侧和远侧区段132a、132b可以以任何合适的方式被稳固在一起,包括利用粘附剂、焊接、机械紧固件等。在实施方式中,管状构件132的近侧和远侧区段132a、132b一体地形成。管状构件132的近侧区段132a的内表面133a(图8)是带螺纹的。带螺纹的内表面133a被配置成接合驱动构件160的带螺纹的部分162c。管状构件132的远侧区段132b被配置成可操作地保持并支撑套管针构件134的近侧端和铰接机构140。更特别地,管状构件132的远侧区段132b限定了:半球形凹部131a,该半球形凹部用于接收套管针构件134的球形部分134a;以及狭槽131b(图10),该狭槽用于接收从铰接机构140的锁定构件142向外延伸的凸舌部分152。
特别参考图7,套管针构件134包括:球形部分134a;凸缘或中间部分134b;以及渐缩或远侧部分134c。套管针构件134的球形部分134a配置成被接收在套管针机构130的管状构件132的远侧区段132b中的半球形凹部131a内。球形部分134a限定了柱形凹部135(图8),该柱形凹部沿着套管针构件134的纵向轴线“x”延伸。如下文将进一步详细描述的,套管针构件134的球形部分134a中的柱形凹部135接收铰接机构140的锁定构件142的锁定突起154,以将套管针构件134定向和稳固处于纵向对准的配置。套管针构件134的球形部分134a包括渐缩表面135a(图8),该渐缩表面围绕柱形凹部135的入口形成,以促进将锁定构件142的锁定突起154接收在柱形凹部135a内。套管针构件134的带凸缘的中间部分134b被配置成与砧座组件例如砧座组件50可操作地接合(图1)。套管针构件134的渐缩远侧部分134c被配置成穿刺组织并促进套管针构件134与砧座组件50的接合。
现在特别参考图5至图10,套管针机构130的铰接机构140包括:锁定构件142、支承构件144和卡环146。如图所示,支承构件144包括第一和第二支承半部144a、144b,但是可以设想到其他配置。铰接机构140的支承构件144将套管针构件134的球形部分134a可旋转地支撑在管状构件132的远侧区段132b中的半球形凹部131a内,并且该支承构件通过卡环146被可操作地保持在半球形凹部131a内。
套管针组件100的铰接机构140的锁定构件142可滑动地设置在管状构件132的远侧区段132b内。锁定构件142包括:大致柱形的本体150;从柱形本体150径向向外延伸的凸舌部分152;以及从柱形本体150向远侧延伸的锁定突起154。柱形本体150限定用于接收驱动构件160的远侧端的凹部151。凸舌部分152被接收在套管针机构130的管状构件132的远侧区段132b中的狭槽131b中,并且允许锁定构件142在锁定或初始位置(图9)与解锁或缩回位置(图13)之间纵向移动。锁定突起154包括渐缩自由端154a,该渐缩自由端被配置成促进将锁定突起154接收在套管针构件134的球形部分134a的柱形凹部135内。
套管针组件100的驱动构件160包括伸长本体162,该伸长本体具有:近侧或接合部分162a、中间支承部分162b、以及带螺纹的或远侧部分162c。驱动构件160的近侧接合部分162a被配置成与设置在配接器组件20内的驱动螺钉(未示出)可操作地接合。驱动构件160的支承部分162b可旋转地接合支承组件120,以允许伸长本体162绕其纵向轴线旋转。带螺纹的部分162c可操作地接合管状构件132的近侧区段132a的内螺纹部分133a,以引起套管针机构130相对于壳体组件110的纵向移动。
现在将参考图8至图15描述套管针组件100的操作。首先参考图8至图10,无论是为临床医生提供预装载在配接器组件20(图1)内的套管针组件100,还是为临床医生提供与配接器组件20分开的并因此需要装载在配接器组件20内的套管针组件,给临床医生的套管针组件100都设置有处于缩回位置的套管针机构130以及铰接机构140的处于锁定位置的锁定构件142。当套管针机构130处于缩回位置时,驱动构件160的远侧端被接收在形成于锁定构件142的柱形本体150中的凹部151内。当铰接机构140的锁定构件142处于锁定位置时,套管针构件134被固定成与驱动构件160的伸长本体162纵向对准。当处于纵向固定位置时,可以以传统方式使用套管针构件134,例如以穿刺组织。
转向图11和图12,如由图11中的箭头“A”指示的,驱动构件160沿第一方向旋转,引起套管针构件134向远侧移动,例如,前进,如图11中的箭头“B”所指示的。在套管针构件134前进期间,锁定构件142保持在锁定位置,其中,锁定突起154被接收在套管针构件134的球形部分134a中的柱形开口135内。以这种方式,套管针构件134保持与驱动构件160的伸长本体162纵向对准。在实施方式中,锁定构件142可以被键接到驱动构件160,使得驱动构件160的缩回引起锁定构件142的缩回。以这种方式,驱动构件160的缩回会使锁定构件142与套管针构件134脱离,由此允许套管针构件134相对于壳体组件110铰接。替代性地,锁定突起154可以直接形成在驱动构件162上。
转向图13至图16,为了使锁定构件142与套管针构件134脱离,临床医生通过套管针机构130的管状构件132的远侧区段132b中的狭槽131b接合锁定构件142的凸舌142a,并且使锁定构件142在近侧方向上移动到解锁位置,例如缩回到解锁位置,如由图13中的箭头“C”所指示的。锁定构件142的近侧移动使锁定构件142的锁定突起154从套管针构件132的球形部分132a中的柱形开口135内撤回。
当铰接机构140的锁定构件142处于解锁位置时,套管针构件134能相对于壳体组件110的端盖114在任何方向上自由铰接。以这种方式,套管针构件134可以相对于壳体组件110(图2和图14)以任何角度定向,以促进将砧座组件50(图2)附接到套管针构件134。
在将砧座组件50附接到套管针构件134之后,通过在相反的第二方向上旋转驱动构件160来使套管针构件134缩回。当套管针构件134缩回到套管针组件100的壳体组件110内时,套管针构件134接合壳体组件110的端盖114,以使套管针构件134与驱动构件160的伸长本体162再对准。套管针构件134的继续缩回使驱动构件160的伸长本体162的远侧端162b接合锁定构件142。随着套管针构件134继续缩回,锁定构件142的锁定突起154接合套管针构件134的球形部分134a。环绕套管针构件134的球形部分134a中的柱形凹部135的开口端的渐缩表面135a,以及锁定突起154的渐缩自由端154a,促进将锁定构件142的锁定部分144接收在柱形凹部135内。
如上所述,将锁定构件152的锁定突起154接收在套管针构件134的球形部分134a中的柱形凹部135内会使套管针构件134与驱动构件160的伸长本体162纵向对准。然后可以使用外科用缝合仪器10(图1)以传统方式完成缝合程序。
现在参考图16至图21,根据本公开内容的另一实施方式的套管针组件被总体上示出为套管针组件200。套管针组件200与上述套管针组件100基本上相似,并且将仅就它们之间的差异进行详细描述。
套管针组件200包括:壳体组件210;支承组件220,该支承组件被支撑在壳体组件210的近侧端上;套管针机构230,该套管针机构可滑动地设置在壳体组件210内;以及驱动构件260,该驱动构件通过支承组件220被可旋转地支撑在壳体组件210内,用于使套管针机构230相对于壳体组件210纵向移动。
套管针组件200的套管针机构230被配置成相对于套管针组件200的壳体组件210纵向移动。套管针机构230通过端盖214被稳固在壳体组件210的管状本体212内。端盖214包括平坦内表面214a(图19)。套管针机构230包括:管状构件232,该管状构件可滑动地设置在壳体组件210内;以及套管针构件234,该套管针构件稳固到管状构件232并从该管状构件向远侧延伸。
如图所示,套管针机构230的管状构件232包括近侧和远侧区段232a、232b。可以设想到,管状构件232可以是整体式的。管状构件232包括:伸长平坦表面231a,上述伸长平坦表面沿管状构件232的相对长度延伸;以及止动表面231b(图19),该止动表面设置成与伸长平坦表面231a的近侧端相邻。套管针机构230的管状构件232的伸长平坦表面231a与壳体组件210的端盖214的平坦内表面214a对准,以使套管针构件232相对于壳体组件210保持在固定的旋转定向。
特别地参考图19,在套管针机构230相对于壳体组件210的纵向移动例如前进期间,套管针机构230的管状构件232的止动表面231b接合壳体组件210的端盖214。管状构件232的止动表面231b与端盖214的接合将套管针机构230保持在壳体组件210内,并阻止套管针构件234从壳体组件210过度延伸。
特别参考图21,套管针组件200的管状构件232的近侧面层(facing,面向)表面233被配置成与设置在壳体组件210的管状本体212与壳体组件210的支承组件220之间的止动构件222接合。在实施方式中,止动构件222包括卡环。止动构件222限制套管针机构230的近侧移动,以阻止套管针机构230在壳体组件210内过度缩回。
现在参考图22至图28,根据本公开内容的另一实施方式的套管针组件被总体上示出为套管针组件300。套管针组件300与上述的套管针组件100、200基本上相似,并且将仅就它们之间的差异进行详细描述。
套管针组件300包括:壳体组件310;可滑动地设置在壳体310内的套管针机构330;以及驱动组件360,该驱动组件被可旋转地支撑在壳体组件310内,用于使套管针机构330相对于壳体组件310纵向移动。
套管针组件300的壳体组件310包括管状本体312以及设置在管状本体312的远侧部分312b上的端盖314。管状本体312的近侧部分312a包括带螺纹的内表面316(图24)。如将在下面进一步详细描述的,管状本体312的带螺纹的内表面316接合驱动组件360的驱动构件362的带螺纹的近侧部分362a,以使驱动构件362相对于壳体组件310的纵向平移。
套管针组件300的套管针机构330被配置成相对于套管针组件300的壳体组件310纵向移动。套管针机构330通过在管状本体312的远侧部分312b上的端盖314和在管状本体312的近侧部分312a上的驱动组件360被稳固在壳体组件310的管状本体312内。套管针机构330包括:管状构件332,该管状构件可滑动地设置在壳体组件310内;以及套管针构件334,该套管针构件被稳固到管状构件332并从该管状构件向远侧延伸。
套管针组件300的驱动组件360包括:驱动构件362;驱动连接器364,该驱动连接器关于驱动构件362的带螺纹的近侧部分362a延伸;柱塞构件366,该柱塞构件可滑动地设置在驱动连接器364内;以及弹簧构件368,该弹簧构件使柱塞构件366偏置。柱塞构件366和弹簧构件368运行以将驱动连接器364保持在近侧位置,例如,与配接器组件20(图1)内的驱动轴(未示出)接合。
驱动组件360的驱动构件362包括带螺纹的近侧部分362a和带螺纹的远侧部分362b。带螺纹的近侧部分362a的沿第一方向设螺纹,而带螺纹的远侧部分362b沿第二方向设螺纹。如上所述,驱动构件362的带螺纹的近侧部分362a被配置成与壳体组件310的管状本体312的带螺纹的内表面316接合。驱动连接器364的旋转引起驱动构件362相对于壳体组件310的纵向移动。驱动构件362的带螺纹的远侧部分362b与管状构件332的近侧部分332a的带螺纹的内表面333接合。驱动构件362的旋转引起套管针机构330相对于壳体组件310的纵向移动。
驱动构件362的带螺纹的近侧部分362a的螺距可以与带螺纹的远侧部分362b的螺距相同或不同。通过改变驱动构件362的带螺纹的近侧和远侧部分362a、362b的螺距,可以改变相应的驱动构件362和套管针机构330在纵向方向上移动的速率。在实施方式中,驱动构件362的带螺纹的远侧部分362b较粗糙(例如,螺纹螺距相对较大),以使套管针机构330移动得更远,同时带螺纹的近侧部分362a较精细(例如,螺纹螺距相对较小),用于在使驱动构件362关于壳体组件310的管状本体312移位和进行轴向保持这两者中进行使用。
驱动组件360的驱动构件362的带螺纹的近侧部分362a限定柱形凹部363,以用于接收驱动连接器364、柱塞构件366和弹簧构件368。垫片365限定矩形开口365a(图22),该垫片被焊接或以其他方式固定地稳固到驱动构件362的带螺纹的近侧部分362a的柱形凹部363内,以将驱动连接器364的带凸缘的远侧端364a保持在柱形凹部363内,并使柱塞构件366相对于驱动构件362在旋转方面固定。更特别地,驱动连接器364的近侧部分364a包括矩形轮廓,该矩形轮廓通过垫片365的矩形开口365a被可滑动地接收。以这种方式,驱动连接器364的旋转引起驱动构件362的旋转。
如上所述,柱塞构件364包括:近侧部分364a,该近侧部分包括矩形轮廓;以及带凸缘的远侧部分364b。近侧部分364a的矩形轮廓使驱动连接器364相对于驱动构件362在旋转方面固定,并且远侧部分364b的凸缘将驱动连接器364保持在驱动构件362的柱形凹部363内。驱动连接器364限定一纵向腔367,该纵向腔用于接收围绕柱塞构件366被接收的弹簧构件368。弹簧构件366通过柱塞构件366的带凸缘的远侧部分366b被保持成围绕柱塞构件366。弹簧构件368被配置成使柱塞构件366向远侧偏置,或者更特别地,使驱动连接器364向近侧偏置。柱塞构件366和弹簧构件368运行以将驱动连接器364保持在近侧位置,以确保驱动连接器364与配接器组件20(图1)的驱动轴(未示出)接合。
特别参照图23和图24,套管针组件300的套管针机构330被示出为处于缩回或远侧位置。当处于缩回位置时,套管针机构330被设置成与驱动构件362的带螺纹的近侧部分362a的远侧端相邻,并且驱动构件362的带螺纹的近侧部分362a的近侧端与被稳固在壳体组件310的管状本体312的近侧端内的垫片318接合,以将驱动构件362保持在管状本体312内,并且用作用于驱动构件312的止动件,以阻止驱动构件312在壳体组件310内过度缩回。
转向图25和图26,驱动组件360的驱动连接器364在第一方向上的旋转——如由图26中的箭头“A”所指示的——引起驱动构件362在相同的第一方向上的对应的旋转。驱动构件362的旋转引起驱动构件362在远侧方向上的纵向移动,例如前进,如由图26中的箭头“B”所指示的。驱动构件362在第一方向上的旋转还会引起套管针机构330在远侧方向上的纵向移动,如由图25中的箭头“C”所指示的。当驱动构件362在壳体组件310内向远侧移动时,驱动组件360的弹簧构件368使驱动连接器364向近侧偏置,以使驱动连接器364保持在近侧位置与配接器组件20(图1)的驱动轴(未示出)接合。
通过在相反的第二方向上旋转驱动连接,套管针机构330返回到缩回位置。
参考图29和图30,在套管针组件300的另一实施方式中,驱动连接器364、柱塞构件366和弹簧构件368被单个活塞构件364'代替。活塞构件364'包括带凸缘的远侧部分364b',该带凸缘的远侧部分具有接收在其周围的密封构件365'。密封构件365'在活塞构件364'的带凸缘的远侧部分364b'与驱动构件362之间产生流体密封。在驱动构件362的纵向移动期间,被接收在驱动构件362的柱形凹部363内的加压流体使活塞构件364'向近侧偏置,以保持活塞构件364'与配接器组件20(图1)的驱动轴(未示出)接触。
参考图31和图32,在套管针组件300的另一实施方式中,柱塞构件366和弹簧构件368被驱动连接器364”所代替,该驱动连接器在驱动连接器364”的近侧部分364a”上具有定位件365”。定位件365”接合配接器组件20(图1)的驱动轴(未示出),以保持驱动连接器364”与驱动轴的接合。尽管示出为包括一个以上的定位件365”,但是可以设想到,驱动连接器364”的近侧部分364a”可以包括仅一个定位件365”。可以进一步设想到,驱动连接器364”可以以其他合适的方式例如摩擦配合、卡口耦接、机械紧固件来稳固到驱动轴。
现在参考图33至图40,根据本发明的另一实施方式的套管针组件被总体上示出为套管针组件400。套管针组件400与上述套管针组件100、200、300基本上相似,并且将仅就它们之间的差异进行详细描述。
套管针组件400包括:壳体组件410;支承组件420,该支承组件被支撑在壳体组件410的近侧端;套管针机构430,该套管针机构设置在壳体410内;以及驱动构件460,该驱动构件通过支承组件420被可旋转地支撑在壳体组件410内,用于使套管针组件430相对于壳体组件410纵向移动。
套管针组件400的套管针机构430被配置成相对于套管针组件400的壳体组件410纵向移动。套管针机构430包括:管状构件432,该管状构件被可滑动地设置在壳体组件410内;以及套管针构件434,该套管针构件从管状构件432向远侧延伸。管状构件432限定开口433,该开口提供通向驱动构件460的伸长本体462的远侧部分462a的入口。管状构件432包括与驱动构件462的带螺纹的远侧部分462b接合的带螺纹的内表面436(图38)。
驱动构件460包括伸长本体462,该伸长本体包括近侧部分462a和带螺纹的远侧部分462b。伸长本体462的带螺纹的远侧部分462b被配置成接合卡环464。更特别地,伸长本体462的远侧部分462b限定用于接收卡环464的凹槽463。尽管被示出为包括卡环464,但是可以设想到,伸长本体462的远侧部分462b可以被代替地配置成接收可以结合、焊接、桩固或以其他方式被稳固到驱动构件462的销、盖或螺母。替代性地,驱动构件460的伸长本体462的远侧部分462b的螺纹可以变形。
参考图37和图38,在套管针机构430的前进期间,卡环464接合套管针机构430的管状构件432的带螺纹的内表面436,以阻止套管针机构430继续前进。该配置在套管针机构430和驱动构件460内包含轴向载荷。以这种方式,套管针组件400的壳体组件410不经受轴向载荷,并且因此不需要被设计得更坚固。
当卡环464接合管状构件432的带螺纹的内表面436时,手柄组件30(图1)的电机中的转矩峰值将向手柄组件30指示套管针机构430的远侧原始位置。该配置允许临床医生校准手柄组件30,而不必完全缩回先前延伸的套管针机构430。
参考图39和图40,套管针组件400的管状构件432的面向近侧的表面433被配置成与设置在壳体组件410的管状本体412和壳体组件410的支承组件420之间的止动构件422接合。在实施方式中,止动构件422包括卡环。止动构件422限制套管针机构430的近侧移动,以阻止套管针机构230在壳体组件410内过度缩回。
将参考图42至图61描述具有套管针机构的套管针组件的实施方式,该套管针机构包括被配置成套管针机构的铰接和旋转的套管针构件。首先参考图41至图44,根据本公开内容的实施方式的套管针组件的实施方式被总体上示出为套管针组件500。套管针组件500与上述的套管针组件100基本上相似,并且将仅就它们之间的差异进行详细描述。
套管针组件500包括:壳体组件510;支承组件520,该支承组件被支撑在壳体组件510的近侧端;套管针机构530,该套管针机构被可滑动地设置在壳体组件510内;以及驱动构件560,该驱动构件通过支承组件520被可旋转地支撑在壳体组件510内,用于使套管针机构530相对于壳体组件510纵向移动。
壳体组件510包括管状本体512和端盖514,该端盖被可操作地支撑在管状本体512的远侧部分512b上。更特别地,管状本体512的远侧部分512a限定切口513a和弧形狭槽513b。切口513a促进将端盖514连接到管状本体512,并且弧形狭槽513b接收端盖514的柱516。端盖514包括大致环形的本体514a,该本体包括相对的平坦内表面514b,上述相对的平坦内表面被配置成将套管针机构530相对于端盖514在旋转方面固定。如将在下面进一步详细描述的,端盖514被配置成使套管针机构530穿其而过来接收该套管针机构,并允许套管针机构530相对于管状本体512旋转。
套管针组件500的套管针机构530被配置成相对于套管针组件500的壳体组件510进行纵向和旋转移动以及铰接。通过端盖514阻止套管针机构530从壳体组件510的管状本体512过度延伸。套管针机构530包括:管状构件532,该管状构件被可滑动地设置在壳体组件510内;以及套管针构件534,该套管针构件被可枢转地稳固到管状构件532并从该管状构件向远侧延伸。
如图所示,套管针机构530的管状构件532包括近侧和远侧区段532a、532b。可以设想到,管状构件532可以是整体式的。管状构件532包括沿着管状构件532的相对长度延伸的伸长平坦表面531a。套管针机构530的管状构件532的伸长平坦表面531a与壳体组件510的端盖514的平坦表面514b对准。管状构件532的伸长平坦表面531a和端盖514的平坦表面514a一起运行,以使套管针构件532相对于端盖514保持在固定的旋转取向。
如上所述,端盖514包括被接收在壳体组件510的管状本体512的远侧部分512b中的弧形狭槽513b内的柱516。端盖514被配置成围绕套管针组件500的纵向轴线“x”旋转。端盖514的旋转以及因此通过端盖514被接收的套管针机构530的旋转受到弧形狭槽513b的长度的限制。弧形狭槽513b的长度越大,端盖514和通过端盖514被接收的套管针机构530的旋转程度越大。
转向图44至图48,套管针组件的另一实施方式被总体上示出为套管针组件600。套管针组件600与上述的套管针组件500基本上相似,并且将仅就它们之间的差异进行详细描述。
套管针组件600的壳体组件610包括管状本体612和端盖614,该端盖被可操作地支撑在管状本体612的远侧部分612b上。更特别地,管状本体612的远侧部分612b限定一对弧形狭槽613。弧形狭槽613接收端盖614的柱616。端盖614包括大致环形的本体614a,该本体包括相对的扁平内表面614b。
特别参考图46,在端盖614被接收在壳体组件610的管状本体612的远侧部分612b内之后,柱616被稳固到端盖614。更特别地,在端盖614的环形本体614a被接收在管状本体612的远侧部分612b之后,将柱616焊接、胶合、机械紧固或以其他方式稳固到端盖614的环形本体614a。以这种方式,柱616运行以将端盖614保持在管状本体612内,并允许端盖614围绕套管针组件630的纵向轴线“x”旋转。
现在参考图49至图52,根据本公开内容的另一实施方式的套管针组件的实施方式被总体上示出为套管针组件700。套管针组件700与上述的套管针组件500、600基本上相似,并且将仅就它们之间的差异进行详细描述。
套管针组件700包括壳体组件710和套管针机构730,该套管针机构被可滑动地设置在壳体组件710内。
壳体组件710包括管状本体712和端盖714,该端盖被支撑在管状本体712的远侧部分712b上。端盖714包括大致环形的本体714a,该环形本体包括从环形本体714a的内表面714b延伸的一对凸部716。如将在下面进一步详细描述的,端盖714的凸部716与套管针机构730的管状构件732的伸长平坦表面731相对应,以允许和限制套管针机构730相对于壳体组件710的管状本体712围绕套管针组件700的纵向轴线“x”的旋转。
套管针组件700的套管针机构730被配置成相对于套管针组件700的壳体组件710进行纵向和旋转移动以及铰接。套管针机构730包括:管状构件732,该管状构件被可滑动地设置在壳体组件710内;以及套管针构件734,该套管针构件被可枢转地稳固到管状构件732并从该管状构件向远侧延伸。
套管针机构730的管状构件732包括沿着管状构件732的相对长度延伸的伸长平坦表面731a。管状构件732的伸长平坦表面731与壳体组件710的端盖714的凸部716对准并对应。管状构件732的伸长平坦表面731提供间隙,该间隙允许通过端盖714接收管状构件732。管状构件732能够从相对于端盖714的第一旋转定向(图50)移动到相对于端盖714的第二旋转定向(图52)。端盖714的凸部716与套管针机构730的管状构件732的接合限制了管状构件732围绕套管针组件700的纵向轴线“x”的旋转。
现在参考图53至图56,在本公开内容的另一实施方式中,套管针机构830包括管状构件832,该管状构件能被壳体组件810的管状本体812可滑动地接收。套管针机构830包括从管状构件832向外延伸的销或柱836。销836配置成被接收在形成于壳体组件810的管状本体812中的纵向狭槽813内。
特别参考图54,壳体组件810的管状本体812中的纵向狭槽813包括窄的近侧部分813a和宽的远侧部分813b。纵向狭槽813被配置成当套管针机构830被接收在管状本体812内时接收套管针机构830的销836。
转向图55,当套管针机构830的管状构件832的销836被接收在壳体组件810的管状本体812内时,通过销836与管状本体812的对纵向狭槽813的窄的近侧部分813a进行限定的壁的接合来阻止套管针机构830旋转。相反,由于限定纵向狭槽813的宽的远侧部分813b的管状本体812的壁之间的间隔,套管针机构830被允许旋转。以这种方式,当套管针机构830处于壳体组件810的管状本体812内的缩回位置时,例如,当销836设置在纵向狭槽813的窄的近侧部分813a内时(图55),套管针机构830被固定而不能旋转运动,并且当套管针机构处于管状本体812内的前进位置时,例如,当销836设置在纵向狭槽813的宽的近侧部分813b内时(图56),套管针机构830能相对于管状本体812自由旋转。
参考图57至图62,根据本公开内容的另一实施方式的套管针组件被总体上示出为套管针组件900。套管针组件900与上述的套管针组件相似,并且将仅就它们之间的差异进行详细描述。
套管针组件900包括:壳体组件910;套管针机构930,该套管针机构被可滑动地设置在壳体组件910内;以及驱动构件960,该驱动构件通过支承组件920被可旋转地支撑在壳体组件910内,用于使套管针机构930相对于壳体组件910纵向移动。
特别参考图58,套管针组件900的壳体组件910包括管状本体912。管状本体912包括纵向切口913,该纵向切口具有窄的近侧部分913a、渐缩中间部分913b以及宽的远侧部分913c。如将在下面进一步详细描述的,纵向切口913允许套管针机构930沿着套管针组件900的纵向轴线“x”旋转。管状本体912的远侧部分912b限定凹口915,以促进套管针机构930在壳体组件910的管状本体912内的装载。
套管针组件900的套管针机构930被配置成相对于套管针组件900的壳体组件910进行纵向和旋转运动。套管针机构930包括:管状构件932,该管状构件被可滑动地设置在壳体组件910内;以及套管针构件934,该套管针构件被稳固到管状构件932并从该管状构件向远侧延伸。套管针机构930通过从管状本体912向外延伸的销或柱936被稳固在壳体组件910的管状本体912内。销936配置成被接收在管状本体912的纵向狭槽913内。
套管针组件900的驱动构件960包括伸长本体962,该伸长本体具有带螺纹的或远侧部分962b。带螺纹的部分962b螺纹接合套管针机构930的管状构件932。套管针机构930的管状构件932通过驱动构件960的伸长本体962的接合将套管针机构930稳固在壳体组件910的管状本体912内。
如图59和图60所示,当套管针机构930处于延伸或前进位置时,从套管针机构930的管状构件932延伸的销936被设置在壳体组件910的管状本体912中的纵向狭槽913的宽的远侧部分913c内。当销936设置在纵向狭槽913的宽的远侧部分913c内时,套管针机构930被允许围绕套管针组件900的纵向轴线“x”从第一位置(图59)旋转到第二位置(图60)。
当套管针机构930缩回到壳体组件910的管状本体912内时,例如,当驱动构件960在第一方向上旋转时,套管针机构930的销936穿过纵向狭槽913的渐缩中间部分913b,并且被引导到纵向狭槽913的窄的近侧部分913a中。当销936设置在纵向狭槽913的渐缩中间部分913b内时,套管针机构930的旋转程度受到管状本体912的限定纵向狭槽913的壁的限制。当套管针机构930的销936被接收在纵向狭槽913的窄的近侧部分913a内时,套管针机构930被阻止围绕纵向轴线“x”旋转。
现在参考图62,套管组件910的管状本体912被示出为,套管针机构930的管状构件932通过凹口915(图58)被接收在管状本体912的远侧部分912b中。在通过凹口915接收套管针机构930的管状构件932之后,管状构件932与驱动构件960对准并进行接合,并且通过驱动构件960螺纹接合,以将套管针机构930保持在壳体组件910的管状本体912内。然后,套管针组件900以传统方式运行。
