Abstract
一种***内窥镜,包括一个伸入***的管式探头(6),其中该探头由一个环形密封件(13)所环绕。该密封件为厚壁聚乙烯泡沫的半球形壳,与探头前端相隔离,它仅仅密封***口的内部组织的圆周区域。该密封件的外表面成旋转面,其中,密封表面的直径随着自密封件前端开始的轴向距离逐渐增加,并且增加率随上述轴向距离逐渐减小。该密封因而在探头进入***深的度限定范围内及探头角度调整的范围内提供了一个低压的密封。
Description
技术领域
本发明涉及一种***内窥镜,它起码用于至少是***子宫颈区域的检查。这种内窥镜主要包括一个管式探头以及附属外部设备,该管式探头能经***口******腔从而能通过***口延伸向内观察。
背景技术
众所周知,检查可以通过肉眼或者由光学或电子摄像机来进行。
大家还知道,优选的***内窥镜也应该可以为外科仪器进入到***腔内部提供途径,例如,为用来检测子***发作的所谓“***抹片检查”收集细胞的组织取样器。
为了方便子宫颈区域的检查以及此类仪器的操作,建议***内窥镜应允许至少是***腔子宫颈端部份能够被空气或其他透明流体所充胀。这就要求内窥镜至少能把***要充胀的那部分密封起来,而一个于内窥镜孔内阻止压力流体从该处溢出的透明流体的密封隔膜或塞子,以及流体的供给方式意味着要么允许压力流体在隔膜或塞子之前抵达内窥镜的腔内,要么直接进入***腔的密封部分。
因而一个全方位功能的***内窥镜是一个复杂的仪器,它不仅包括进入***实际的管式探头,而且还有所述的外部设备,这些外部设备又可能包括一个操作探头的手柄,一个能够让操作者瞄准并定位探头的目镜,一个照明子宫颈区域的光源,一个摄像头或者至少是连接一个摄像头的装置,带压透明流体和普通空气的供给装置,以及在压力下保留空气或其他流体在***内的密封装置。
当然最基本的是至少管式探头在******前是消毒的。因而对于管式探头来说,易与外部设备分离或连接是常识性的,即,既要使得其在进行不同手术之间被消毒,或者更优选的是在一个手术结束之后将其弃置并为下一个手术换上没有使用过的探头。国际专利申请PCT/AU97/00732(Superior Spec Holdings Limited公司)(国际公开号WO/98/19590),描述了一个现有的***内窥镜,公开了具有上述多种特点的实施方案。
现有的内窥镜包括装有一个可充胀密封置于探头前端的一次性使用的管式探头。在这种内窥镜的临床使用上,证明其基本令人满意,但也发现其密封的中央效果导致对偏离***中央的区域检查上的一些困难。实际上在某些少数情况下,子宫颈本身可能会因其位置不正而导致检查困难。
发明的公开
本发明的一个目的便是减少因密封位于或接近管式探头前端所产生的一些问题。
本发明通过提供一个***密封件环绕管式探头两端的中间而达到所述的目的,所述的密封件为这样的形状以使得其可以用来接触和密封***口的身体组织。这种密封定位比以前的密封定位留出了更多的***腔做检查,更重要的是,对于子宫颈的检查来说,它使得探头前端能够更迅速的定位,从而视线能够更迅速地瞄准。在下文中,当根据本发明的内窥镜密封件接触***腔外的组织时,称其为一个外部***密封,即使所讨论的组织不是被检查妇女的皮肤。
在某些相类似的使用情况下,德国专利说明书DE 44 04 253揭示并涉及一种***内窥镜的密封。它使用的是喇叭口或喇叭裙形状的***密封,有着通常的放射状扩展边缘的凹面。该密封比上述本发明特征的***外密封要更加完全地外露,因为至少密封件的放射状扩展边缘接触到被检查者***四周的皮肤。在获得本发明的实验中,发现具有德国专利说明书所公开的形状的密封件用于涉及***内窥镜时是不可行的。
***内窥镜外部密封问题的产生是因为***口大小和形状在不同的妇女之间有着很大程度的不同。如果使用一个调整放射状突出边缘去接触并且密封***口周围皮肤的密封件,那么该密封件便实际确定了内窥镜探头进入***的程度。然而因为不同妇女间***内部尺寸的多样性,探头的深度必须由操作者调节从而将探头的顶部调节到一个与子宫颈合适的距离。尽管妇女身体的尺寸和***的外形使一个有经验的操作者能在任何情况下估计出探头所需的大约长度,但在***完成之前很难对探头的***深度进行精确的调节(并且随后的污染阻止了该探头的再次使用)。因而,密封件必须被保留在探头深度限定的范围之内,这一点又与放射状扩展边缘和环绕***口的外部体表之间的密封不相符合。
本发明通过提供一个如前所述定位于管式探头上的密封件克服了上面提到的问题,该密封件在使用时位于***的外部并且仅仅密封***口的内部组织的圆周区域。所以该密封件无放射状扩展边缘,它具有一个做成旋转面的密封表面,其中,所述的密封表面的直径自密封件前端开始的轴向距离逐渐增加,而且增加率随上述的轴向距离逐渐减小。
根据本发明的密封件,它依靠环绕***口被称为PC肌肉的本身弹性来允许***口扩展和收缩,从而使密封件能伸入***口并随后在整个进入深度的限定范围内保持密封。
因而本发明涉及这样一种***内窥镜,它包括一个伸入***腔的管式探头,其特征在于该探头由一个与探头前端相隔离的环形密封件所环绕,所述的密封件仅仅密封***口的内部组织的圆周区域并且被做成一个旋转面的形状,其中,所述的密封表面的直径自密封件前端开始的轴向距离逐渐增加,而且增加率随所述的轴向距离逐渐减小。
更简单地说,密封件的优选实施方案可以描述成一个没有放射状扩展边缘的凸起圆顶,它的中央有一个环形的开口,通过这个开口,管式探头密封地延伸。
附图简要说明
下面通过举例的方式,对本发明的一个实施方案进行描述。
图1为本发明***内窥镜的管式***探头和外密封件的纵向剖视图。
图2为图1所示的探头和密封件与***内窥镜的典型和常规组件装配在一起的部分剖视图。
图3为一个垫片的侧视图。
图4为图3所示垫片的纵向剖视图。
图5为本发明内窥镜的管式探头和密封件***通过一个充胀的***的剖视图。
图6与图5相似,但其中的***具有相对更大或更松弛的***口。
实施本发明的最佳方式
图1示出了一个易处理的***内窥镜管式探头6。探头6配有一个常用的卡圈7和尾部稍微成锥形的套管8,套管8***一个用于调节探头的常用的手柄9(见图2),一个使操作人员能够瞄准探头并直接看见***子宫颈区域的目镜10,以及一个光源及气泵的箱11。箱11通过软管12与手柄相连接。一根光缆延伸通过管12使***的子宫颈区域被通过该光缆并穿过探头6透明壁的光所照亮。泵送的压缩空气也沿着管11流经手柄9的内部,并通过空气供给部件13进入探头6的腔内。空气供给率可由内窥镜操作者进行调节。目镜10也密封住探头6的尾部以防止空气从该端泄漏出去。
在以上的描述,图1和图2涉及的主题已为人所知,然而图示的内窥镜还进一步包括一种新型的密封部件13,与现有技术相比较,它具有相当明显的优越性。
图5及6示出了一个充胀的***腔14,子宫颈15在其里面的一端,而***口由环状***16,即所谓的PC肌限定在外侧的一端。
依照本发明的实施方案,部件13是一个闭腔的厚壁空心半球,由致密聚乙烯泡沫制成,中间有孔,通过所述的孔,探头6密封地延伸。密封部件13通过一个与探头6一体连接的环状支撑件17防止它沿着探头滑向如图1和图5所示的右边。
从图5可以看出,密封件13已部分挤入通过PC肌因而扩大了***口的前部并使其密封接触***口正常内表面的环形区域18。应该指出的是,所述的密封件不是一个高压密封件,例如当一个密封件上的放射状扩展边缘由操作者推得过于紧地抵住环绕***口的外部区域20时所产生的高压。这一点在防止***腔14超压上构成了一个重要的安全措施,在超压的情况下,区域18进一步膨胀而使压力流体流出。
图6显示了一个***剖面图,由于天然的多样性或者由于年纪或生孩子的经历而导致肌紧张性的失去,该***口被扩大或PC肌比通常情况下更松弛。考虑到这些因素,操作者在安装密封件13前可以放置一个或多个垫片21到探头6上(见图6)。因而在这种情况下,为达到满意的密封效果,所需密封件向***口内更大的突入可以适应于探头6的顶部与子宫颈15仍然保持所需的距离。
进一步地,密封件13的形状使得在一定的角度范围内对探头进行调节时仍可保持低压密封,而这种调节在对子宫颈进行检查时可能是必需的。
