Description

用于多摄影机内窥镜的多元件罩
发明领域
本公开内容的实施方案涉及一种多摄影机内窥镜的顶端部分的多元件罩。
背景
内窥镜在医学界已经得到了巨大的认可,因为它们提供一种用于以最小的患者创伤进行程序的手段,同时使得医师能够观察到患者的内部解剖。多年来,根据具体应用,许多内窥镜已经被开发和分类,例如膀胱镜检查、结肠镜检查、腹腔镜检查、上消化道内窥镜检查和其他的。内窥镜可以被插入身体的天然孔口或者插入通过皮肤中的切口。
内窥镜通常是长形的管状的杆状物,坚硬的或柔性的,在其远端具有视频摄影机或光纤镜头组件。所述杆状物与把手连接,把手有时候包括用于直接观察的目镜。观察通常也可以经由外部屏幕。各种外科工具可以被插入通过内窥镜中的工作通道,用于进行不同的外科程序。
目前正被使用的内窥镜例如结肠镜,通常具有用于观察内脏如结肠的前面摄影机、照明器、流体注射器,流体注射器用于清洁摄影机镜头,且有时候也清洁照明器和用于外科工具的插入的工作通道,例如用于清除在结肠里发现的息肉。时常,内窥镜还具有用于清洁它们被插入其中的体腔例如结肠的流体注射器(“喷射”)。普遍使用的照明器是将远程产生的光传输至内窥镜顶端部分的光纤。发光二极管(LED)用于照明的用途也是已知的。
在这样的内窥镜的缺点中的是它们的有限的视野和它们的所有必需元件的复杂包装,例如电子设备和光纤与流体携带元件一起在小尺寸的内窥镜顶端部分中。现有的内窥镜的其他问题是轻柔的电子部件的困难的组装,它们常常被组装过程本身损坏。现有的内窥镜的另一个问题是部分尤其是在内窥镜的顶端部分中的部分的复杂的密封。顶端部分的密封仍然是挑战,特别地由于在其中操作内窥镜的复杂环境。
因此,本领域中对允许较宽的视野且还实现顶端部分中所有必需的元件的高效的包装、组装和密封,同时维持它们的功能的内窥镜例如结肠镜存在需求。
相关技术的前述例子和与其有关的局限性意图是说明性的而不是排他的。本领域的技术人员在阅读说明书和研究附图之后,相关技术的其他局限性将会变得明显。

详述
尽管在上面已经讨论了许多示例性的方面和实施方案,但本领域的技术人员将认识到它们的某些修改、排列、增加和子组合。因此,意图以下所附的权利要求和下文介绍的权利要求应被解释为包括所有这些修改、排列、增加和子组合,如在它们的真实精神和范围内一样。
在本申请的描述和权利要求中,每个词“包含”“包括”和“具有”以及它们的形式,不一定限于与所述词相关联的列表中的成员。
现在参照图1a,图1a示意性地描述根据本发明的示例性的实施方案的具有多部件顶端罩(以分解图显示)的内窥镜的顶端部分(包括携带摄影机和照明源的电子电路板,和流体引导部件)的等距视图,且参照图1b,图1b示意性地描述根据本发明的一些示例性的实施方案的图1a的具有组装的多部件顶端罩的顶端部分的等距视图。
顶端部分100通常包含内部部分(inner part)110,其包括电子设备(例如摄影机、电路板例如电子电路板400、照明源例如LED等等)、流体通道(例如流体引导部件600)和多元件顶端罩700。多元件顶端罩700被设计成配合在顶端部分100的内部部分之上,且向内部部分中的内部部件提供保护。根据该实施方案,多元件顶端罩700包括三个部分:前面部件710,其被配置成覆盖顶端部分的前面部分;右侧面部件730,其被配置成覆盖顶端部分的右侧面部分;和左侧面部件750,其被配置成覆盖顶端部分的左侧面部分;其中前面部件、右侧面部件和左侧面部件被配置成以使得它们本质上覆盖顶端部分的所有内部部分的方式邻接彼此以覆盖顶端部分。
前面部件710包含:孔736,其被配置成与前视摄影机116的前面光学组件236对齐(且容纳该前面光学组件236);LED240a、240b和240c的光学窗口242a、242b和242c;工作通道(未显示)的远端开口340;喷射流体通道644的远端开口344;和冲洗和注气(irrigation and insufflation)(I/I)注射器346,其具有喷嘴348(与流体引导部件600的开口664对齐)。
左侧面部件750包含:孔756b,其被配置成与侧视摄影机220b的侧面光学组件256b对齐(且容纳该侧面光学组件256b);在光学组件256b的两侧上的LED250a和250b的光学窗口252a和252b;侧面I/I注射器266b,其适合于与流体部件600的侧面I/I开口666b对齐。在图1a和图1b中还看到侧面I/I注射器266a(未显示)和266b的喷嘴267a和267b。
右侧面部件730包含与左侧面部件720(未显示)相似的元件。
左侧面部件750和右侧面部件730各自是本质上半圆筒(没有顶部和底部)的形状。
前面部件710本质上具有杯子形状,其有垂直地延伸到杯子底部(其也可以被称为杯子的前面)且从杯子边缘突出的两个相对的臂712和714。在组装顶端罩部件之后,可首先组装前面部件710,且然后组装侧面部件,使得它们的长边缘在两个侧面上在臂712和714之上彼此相遇以确保密封(图1b)。粘合剂例如胶水,可以被添加在例如空腔716(沿着部件710的边缘的外部部分)、718(沿着部件730的内部边缘)和720(沿着部件750的内部边缘)中,以实现顶端部分100的完全密封。
根据本发明的实施方案的多元件顶端罩,例如多元件顶端罩700或任何其他在此公开的多元件顶端罩,解决了当尝试将所有必需的部件包装在内窥镜顶端的小内部体积中并且覆盖和密封这些部件时本领域存在的重大问题。规则杯子状的顶端罩被用于具有仅一个前面摄影机的标准顶端。然而,当标准杯子状的顶端罩被用来覆盖多摄影机顶端时,突出的内部顶端元件,例如侧面光学组件的镜头或其他部件,在所述罩在它们上方滑动时常常被损坏。使用多元件顶端罩可以解决此问题。另外,多元件顶端罩帮助将它的孔/开口/窗口精确地对准在相应的顶端内部元件之上的它们的恰当的位置。使用单件罩这几乎是不可能的。而且,单独密封多元件顶端罩的元件中的每个改进顶端的整体密封,这是由于与在单件罩例如杯子状罩中同样的元件的有限接近相比,更好地接近每个元件(例如光学窗口)。多元件顶端罩的元件中的每个的单独密封(且任选地检查令人满意的密封)可以在组装罩之前被执行。这也可以改进顶端的密封。
根据本发明的实施方案,内窥镜的顶端部分100包括至少一台前视摄影机和至少一台侧视摄影机。顶端部分100是可通过挠性轴(未显示)转动的,所述挠性轴也可以被称作弯曲部分,例如脊椎机构(vertebramechanism)。
在一些实施方案中,前视摄影机和/或任何侧视摄影机包括电荷耦合装置(CCD)或互补金属氧化物半导体(CMOS)图像传感器。
应注意,在此提及的术语“内窥镜”可以特别地是指根据一些实施方案的结肠镜,但不仅仅限于结肠镜。术语“内窥镜”可以是指用于检查身体的中空器官或空腔的内部的任何仪器。
顶端部分100可以包括前视摄影机116的前面光学组件236。前视摄影机116的光轴是基本上沿着内窥镜的长尺寸定向的。然而,因为前视摄影机116通常是宽角摄影机,所以其视野(FOV)可以包括与其光轴成大角度的观察方向。应注意,用于照明FOV的照明源例如LED的数目可以改变(例如,1-5个LED可以被用在顶端部分100的前表面上)。工作通道(未显示)的末端开口340也位于顶端部分100的前表面上,使得通过工作通道管,且通过在内窥镜的顶端部分100中的工作通道插入且展开超出前表面的外科工具可以通过前视摄影机116观察到。
喷射流体通道的远端开口344也位于顶端部分100的前表面上。喷射流体通道的远端开口344可以被用于提供流体例如水或盐水的高压喷射,用于清洁体腔的壁。
具有对准前面光学组件236的喷嘴348的冲洗和注气(I/I)注射器346,也位于顶端部分100的前表面上。I/I注射器346可以用于注射流体(液体和/或气体)以从前视摄影机的前面光学组件236洗涤污染物,例如血、粪便和其他碎屑。可选择地,同样的注射器用于清洁前面光学组件236、和光学窗口242a、242b和242c中的一两个或全部。I/I注射器346可以通过可以用于清洁体腔和/或给体腔充气的流体例如水和/或气体来进料。
侧视摄影机220b的侧面摄影机(侧视摄影机)元件256b和用于摄影机220b的LED 250a和250b的光学窗口252a和252b在顶端部分100的左侧面上是可见的。第二侧视摄影机220a,没有显示在图1a中但可以与摄影机220b相似。侧视摄影机220a的光轴实质上被定向成垂直于内窥镜的长尺寸。侧视摄影机220b的光轴实质上被定向成垂直于内窥镜的长尺寸。然而,因为侧视摄影机220a和220b通常是宽角摄影机,所以其视野可以包括与其光轴成大角度的观察方向。
具有对准侧面光学组件256b的喷嘴267b的侧面I/I注射器266b,可以用于注射流体以从侧视摄影机的侧面光学组件256b洗涤污染物,例如血、粪便和其他碎屑。流体可以包括可以用于给体腔充气的气体。可选择地,同样的注射器用于清洁侧面光学组件256b和光学窗口252a和/或252b。应注意,根据一些实施方案,顶端可以包括在侧面上不只一个窗口和LED,且在前面中不只一个窗口和LED(例如,在侧面上1—5个窗口和2个LED)。I/I注射器和喷嘴的相似构型存在用于清洁光学组件256a和位于顶端100的其他侧面上的光学窗口252a'和252b’(未显示)。I/I注射器被配置成清洁这些窗口/LED的全部或一部分。侧面I/I注射器346和266可被从同一个通道进料。
应注意,侧壁362具有基本上平的表面的形式,这帮助将从侧面I/I注射器266a(未显示)和266b注入的清洁流体引导向侧面光学组件256b和光学窗口252a和/或252b。缺乏这样的平面可以导致清洁流体沿着内窥镜的顶端部分100的弯曲表面滴下,而没有进行所需的清洁作用。
应注意,尽管仅仅一个侧视摄影机在图1a和图1b中被看到,但优选地至少两个侧视摄影机可位于顶端部分100中。当两个侧视摄影机被使用时,侧视摄影机被优选地组装为使得它们的视野是实质上相对的。然而,不同构型和数目的侧视摄影机可能在本发明的大体范围里。
根据一些实施方案,用于携带电子部件例如摄影机和/或LED的电路板,可以是柔性电路板,其可以使用较少的空间且留更多的体积给附加的必要的特征。板的柔性增加可以用于部件定位的另一空间尺寸。
根据本发明的实施方案的柔性电路板的使用可以显著增加到其的电模块连接的可靠性,因为没有线用于部件连接。另外,根据一些实施方案,部件组装可以是机械的和自动的。
根据本发明的实施方案的柔性电路板的使用还可以允许在摄影机头部(内窥镜的顶端)组装期间部件(零件)运动和可操作性,同时维持高水平的可靠性。根据本发明的实施方案的电路板的使用还可以简化(顶端)组装过程。
根据一些实施方案,柔性电路板可以经由多电线电缆被连接到控制单元;该电缆可以在指定的位置被焊接在板上,在顶端组件内释放额外的空间和增加电缆进入的灵活性。将多电线电缆直接组装到电部件是主要的挑战,其通过使用根据本发明的实施方案的柔性板而被减轻。
现在参照图2,其示意性地描述根据本发明的示例性的实施方案的具有多部件顶端罩(以分解图显示)的内窥镜的顶端部分(包括携带摄影机和照明源的电子电路板,和流体引导部件)的等距视图。顶端部分200通常包括内部部分210,其可以与图1a-b的顶端部分100的内部部分110相似;和多元件顶端罩800。多元件顶端罩800被设计成配合在顶端部分200的内部部分之上,且向内部部分中的内部部件提供保护。根据该实施方案,多元件顶端罩800包括,主要部件830,其被配置成覆盖顶端部分的大部分;和可拆卸窗口部件850,其被配置成覆盖位于主要部件830上的窗口开口860,使得可拆卸窗口部件850被配置成允许在没有拆卸主要部件830时接近顶端部分200的内部部分210。这可以允许固定或更换内部部分210的部件中的一个(例如LED、光学元件或任何其他元件),而没有拆卸主要部件830和损坏顶端部分200的包装和密封。
主要部件830本质上具有杯子形状,具有被配置成覆盖顶端部分200的前表面的前面部分和被配置成覆盖顶端部分200的侧面的杯子边缘。
主要部件830还可以包括与图1a和图1b的多部件罩700的那些相似的前面的和侧面的孔、开口、窗口和表面。
现在参照图3,图3示意性地描述根据本发明的示例性的实施方案的多部件顶端罩的分解图。多元件顶端罩900被设计成配合在顶端部分的内部部分(未显示)之上,且向内部部分中的内部部件提供保护。根据该实施方案,多元件顶端罩900包括:前面一侧面部件930,其被配置成覆盖顶端部分的前面部分和侧面部分;和侧面部件950,其被配置成覆盖顶端部分的另一侧面部分,其中前面一侧面部件930和侧面部件950被配置成邻接以覆盖顶端部分。
现在参照图4a-c。图4a示意性地描述根据本发明的示例性的实施方案的具有多部件顶端罩(以分解图显示)的内窥镜的顶端部分(包括携带摄影机和照明源的电子电路板、电子电路板固定器、流体引导部件)的等距视图)。图4b示意性地描述根据本发明的示例性的实施方案的图4a的具有多部件顶端罩(部分地以分解图)的顶端部分的等距视图。图4c示意性地描述根据本发明的示例性的实施方案的图4a-b的具有多部件顶端罩的顶端部分的等距视图。
顶端部分1000通常包括:内部部分1100,其包括电子设备(如摄影机、电路板、LED等等)、流体通道(如流体引导部件1600)和多元件顶端罩1010。多元件顶端罩1010被设计成配合在顶端部分1000的内部部分之上,且向内部部分中的内部部件提供保护。根据该实施方案,多元件顶端罩1010包括两个部分:远端部件1050,其被配置成覆盖顶端部分的远端部分;和近端部件1030,其被配置成覆盖顶端部分的近端部分,其中远端部件和近端部件被配置成邻接以覆盖顶端部分。远端部件1050具有带有侧壁1052和前表面1054的圆筒的形状,前表面1054被配置成覆盖顶端部分1000的内部部分1100的前面部分1102,且近端部件1030具有带侧壁1032没有顶部或底部的圆筒的形状,其被配置成覆盖顶端部分1000的内部部分1100的近端部分1104。
远端部件1050包括在其前表面1054上的孔1056,其被配置成与前视摄影机1116的前面光学组件1236对齐;LED 1240a、1240b和1240c的光学窗口1242a、1242b和1242c;工作通道(未显示)的远端开口1340;喷射流体通道1644的远端开口1344;和I/I注射器1346(与流体引导部件1600的开口1664对齐)。
远端部件1050还包括在其侧壁1052上的LED 1250a的光学窗口1252a和在侧壁1052的相对侧上的另一LED的另一光学窗口(未显示)。
远端部件1050还包括在其侧壁1052的边缘上的凹处1756′(基本上呈半孔的形状),其被配置成容纳(连同近端部件1030的侧壁1032的边缘上的凹处1756")侧视摄影机1220b的光学组件1256b。在侧壁1052的相对侧上可以有相似的凹处(未显示)来容纳(连同近端部件1030的侧壁1032的边缘上的另一凹处)位于内部部分1100的另外一个侧面(未显示)上的侧视摄影机1220a的光学组件1256a。
近端部件1030包括在其侧壁1032上的LED1250b的光学窗口1252b和在侧壁1032的相对侧上的另一LED(未显示)的另一光学窗口1252a。
近端部件1030还包括在其侧壁1032的边缘上的凹处1756'’(基本上呈半孔的形状),其被配置成容纳(连同远端部件1050的侧壁1052的边缘上的凹处1756′)侧视摄影机220b的光学组件1256b。在侧壁1032的相对侧上可以有相似的凹处1756"来容纳(连同近端部件1050的侧壁1032的边缘上的另一凹处)位于内部部分1100的另外一个侧面(未显示)上的侧视摄影机1220a的光学组件1256a。
近端部件1030还包括侧面I/I注射器1266b,其适合于与侧面I/I开口1666b对齐。
顶端部分1000的内部部分1100的其他部分通常可以与图1a_b的顶端部分100的内部部分1100相似。
将顶端部分1000组装在内部部分1100之上的方法包括从顶端部分1000的远端部分组装远端部件1050;从顶端部分1000的近端部分组装近端部件1030;和将远端部件1050和近端部件1030沿着它们的边缘(线1500)连接,使得没有顶端罩部件在侧视摄影机的光学组件上滑动。
尽管已经结合本发明的具体的实施方案描述了本发明,但很明显,许多备选方案、修改和变化形式对本领域技术人员来说将是明显的。因此,意图包括落在所附的权利要求的精神和宽范围内的所有这些备选方案、修改和变化形式。本说明书中提及的所有出版物、专利和专利申请在此通过引用整体并入到说明书中,达到如同每个单个的出版物、专利或专利申请被特别地和个别地指示通过引用并入本文的同样程度。另外,本申请中引用或认同任何参考文献不应被解释为承认这样的参考文献作为本发明的现有技术可得到。
