具体实施方式
现将参看图式来详细地描述当前公开的可植入紧固件和紧固件施用器的实施例,在图式中类似的参考标号表示若干视图中的每一个中的相同或对应元件。在图式中且在随后的描述中,术语“近端”将指可植入紧固件和紧固件施用器的最接近于操作员的末端,而术语“远端”将指可植入紧固件和紧固件施用器的最远离操作员的末端。
根据本公开,如图1A到1C中所说明,提供可植入紧固件100的实施例,且其大体上包含主体102和从主体102延伸的组织穿透部分104。主体102包含冠面或后跨部106,且组织穿透部分104包含从后跨部106的第一端部106a延伸的第一支腿108和从后跨部106的第二端部106b延伸的第二支腿110。第一支腿108与第二支腿110可在相同方向上,例如从后跨部106远端地延伸。
后跨部106包含被配置成用于在上面固定地支撑胶囊112的顶部或组织对向表面106c。据设想,胶囊112包含辐射源,如将在下文详述。胶囊112使用激光焊接或其它合适的方法附着到后跨部106的组织对向表面106c。在一些实施例中,如图1C中所说明,组织对向表面106可包含沿着其至少一部分延伸且被配置成提供用于在上面附着胶囊112的增大的表面区域的扁平表面106d。在实施例中,胶囊112可使用扣合啮合来附着到后跨部106的部分,例如组织对向表面106的扁平表面106d。后跨部106可接着被加热或压接以降低胶囊112从可植入紧固件100位错和迁移的机率。预期将胶囊112附着在后跨部106的组织对向表面106c上可以是有利的,这是因为其使得胶囊112能够与例如组织等等(见图10)的目标手术部位直接接触。举例来说,预期胶囊112与目标手术部位之间的直接接触可向目标手术部位提供辐射的受控、均匀的剂量,同时避免正常包围性结构的相当大的剂量。进一步预期胶囊112与目标手术部位之间的直接接触可提供从辐射源到目标手术部位的剂量的减小的衰减。替代地,如图2A和2B中所展示,胶囊112可附着到后跨部106的底表面106e或侧表面106f。虽然图中未具体展示,但是预期第一支腿108、第二支腿110可使用激光焊接、压接或其它合适的方法直接附着到胶囊112上。
可植入紧固件100可具有未成形条件,如图1A中所展示,其中第一支腿108与第二支腿110彼此平行或大体上平行,且彼此间隔开某段相对距离。可植入紧固件100可具有成形条件,如图1B中所展示,其中第一支腿108与第二支腿110是辐射状的,且相对紧密地接近彼此和后跨部106。
可植入紧固件100可从可成形材料制造,可成形材料例如钛、不锈钢或聚合物。以此方式,当在未成形条件下时,可在目标容器或组织上方引入可植入紧固件100,并接着使可植入紧固件100形成或紧固到目标容器或组织上以将可植入紧固件100紧固到目标容器或组织。预期可植入紧固件100可从所属领域的技术人员已知的任何不可降解、生物兼容性材料制造。进一步预期可植入紧固件100或其任何部分可由例如镁等可降解材料形成。
根据本公开,如图1A到2B中所说明和上文所提及,可植入紧固件100可包含具有辐射源的胶囊112。胶囊112可以是近距离放射治疗胶囊或种子,并包含在其中安置的放射性材料112a。放射性材料112a可包含数个放射性同位素中的任一个。可能的低剂量同位素包含但不限于铯131(131Cs)、铱192(192Ir)、碘125(125I)钯103(103Pd)和镱169(169Yb)。取决于同位素和所期望的曝光,疗法剂量可范围介于80到150Gy。可植入紧固件100可具有各种目标能量以提供计划治疗的灵活性。据设想,辐射场的特定强度和/或辐射场的特定几何形状可以是放射性材料112a的功能。进一步设想,胶囊112可被设定尺寸以便确定发射出的辐射的几何形状或发射出的辐射的强度。预期胶囊112的长度可小于后跨部106的长度以便不干扰可植入紧固件100的成形。
虽然图中未具体展示,但是预期第一支腿108、第二支腿110和/或后跨部106可包含用于收纳胶囊112或放射性材料112a的一个或多个空腔。胶囊112的放置的任何其它组合以及可植入紧固件100中的胶囊112的集成也被预期,且处于本公开的范围内。
进一步设想,可处理可植入紧固件100使得可植入紧固件100的整体发射来自贯穿可植入紧固件100分散的放射性材料112a的辐射。举例来说,且在本公开的范围内,可处理可植入紧固件100以便确定发射出的辐射的强度。具体地说,在实施例中,可植入紧固件100可以是从放射性生物兼容性材料制造的聚合性手术夹片。
预期在其中安置有放射性材料112a的可植入紧固件100可以是可使用例如X射线等等成像技术来定位的。在可植入紧固件100不包含放射性材料112a的实施例中,可植入紧固件100可涂布有例如金等材料,或涂布有有色氧化物层以使可植入紧固件100相对更可见。金涂层或其它涂层可用以在跟踪工序期间实现对可植入紧固件100的放射性定位。以此方式,可植入紧固件100可充当信托标记。
根据本公开,通过将可植入紧固件100紧固到目标容器或组织上,可基于胶囊112的活性和同位素材料而将治疗剂量的辐射施加到已设定位置和已知体积的组织。
在实施例中,包含胶囊112的可植入紧固件100起到在移除了癌症肿瘤之后向例如肿瘤或向切除部位施加局部治疗剂量的辐射的作用。因而,包含胶囊112的那些可植入紧固件100需要仅充足的机械强度以将胶囊112紧固在适当的位置,并可不意图将组织固持在一起。但是,多个可植入紧固件100可包含被设计成具有充足的机械强度以组织固持在一起的一个或多个可植入紧固件100。替代地,包含胶囊112的可植入紧固件100可被设计成具有充足的机械强度以组织固持在一起同时还将胶囊112紧固在适当的位置。
可植入紧固件100可被施加或紧固到具有肿瘤生长或疑似包含癌细胞的任何数目个非织物,例如肺组织、实体器官、肠胃组织和软组织。
根据本公开,据设想可植入紧固件100可由临床医生在预定位置处单独地且个别地施加。预期胶囊112具有具有已知辐射强度和几何形状的已设定三维场,因而,包含胶囊112的多个可植入紧固件100可施加到目标组织以向目标手术部位提供辐射的受控、均匀的剂量。
预期可以任何配置、任何图案或任何量来施加或布置可植入紧固件100以实现预期的目的。举例来说,可植入紧固件100可布置于例如直线、拱形、三角形、矩形、圆形或其它配置中。进一步预期可植入紧固件100可彼此按相同距离紧固到目标组织,以实现所期望的放射量测定。替代地,可植入紧固件100可彼此按各种距离或其组合紧固到目标组织。
根据本公开,虽然已详细展示并描述了呈可植入紧固件100形式的可植入紧固件,但是预期可植入紧固件可包含并不限于手术钉、手术线圈等等。如上文提到且如本文所预期,可植入紧固件中的任一个可从生物兼容性材料制造,例如钛、不锈钢或聚合物。同样地,如上文提到且如本文所预期,可植入紧固件中的任一个可在其中并入有或在其上制程具有放射性材料112a的胶囊112,或可被处理使得可植入紧固件的整体发射辐射。
举例来说,参考图3A和3B,展示呈“B形”手术钉形式的可植入紧固件,且一般将其表示为200。类似于可植入紧固件100,可植入紧固件200可大体上包含主体202和从主体202延伸的组织穿透部分204。主体202包含冠面或后跨部206,且组织穿透部分204包含从后跨部206的第一端部206a延伸的第一支腿208和从后跨部206的第二端部206b延伸的第二支腿210。

紧固件施用器500包含:本体部分510,其具有手柄总成520;内窥镜轴总成530,其从手柄总成520延伸;滤筒总成540,其从内窥镜轴总成530延伸;以及致动总成550,其至少部分地支撑在手柄总成520内。
内窥镜轴总成530以可旋转方式连接到手柄总成520,使得内窥镜轴总成530可围绕其纵向轴线“X1-X1”旋转。滤筒总成540以可枢转方式连接到内窥镜轴总成530的远端部分,并可相对于内窥镜轴总成530的纵向轴线“X1-X1”枢转。在图9中,滤筒总成540展示为与内窥镜轴总成530的纵向轴线“X1-X1”大体对准,并另外以虚线展示以说明一系列移动或铰接。如所展示的滤筒总成540的枢转运动的总范围是大约90度,即,对每个中立侧45度。
参看图10,内窥镜轴总成530在分解视图中为方便说明起见而展示为部件分离,并包含上部外壳半剖面530a和下部外壳半剖面530b。驱动总成531定位于上部壳体半区段530a和下部壳体半区段530b内。驱动总成531大体上包含推动器或驱动杆532和砧座延伸部533,并在操作上耦合到滤筒总成540以啮合滤筒总成540中支撑的可植入紧固件100。

在进一步致动致动总成550之后,即刻足够地在远端推进长毛板534,以致使最远端可植入紧固件100穿透组织并在组织上成形以紧固胶囊112。具体地说,推动器板534包含一对焊盘534a、534b以促进将推进力传动到后跨部106的第一端部分106a和第二端部分106b。砧座板542被定位用于与后跨部106啮合,使得通过推动器板534的所述对焊盘534a、534b啮合可植入紧固件100与可植入紧固件100的第一端部分106a和第二端部分106b将致使可植入紧固件100以预定方式在组织周围成形并紧固。

紧固件施用器700可配置成在完全发射次序期间发射或递送可植入紧固件400、800、900。紧固件施用器700还可配置成铰接以便促进从其发射可植入紧固件400、800、900。

通过实例,能够以任何几何形状、图案和/或密度来将可植入紧固件100、200、300、400、800、900紧固到目标组织部位,例如肺切除手术过程中的肺组织,可相当适用于肺癌患者,其中许多肺癌病人遭受受损的肺容量且无法容许不必要的肺容量损耗,并可需要多行近距离放射治疗源以确保具有不充分窄的切缘的治疗。
在本文中公开的实施例中的任一个中,可植入紧固件100、200、300、400、800、900可并入到是电动手术系统或机器人手术系统的部分的装置中或配置成用于与所述装置一起使用。
