Abstract

一种內镜取物袋（100），含袋壁（1）、纳物空间（2）、开口端（3）、开口端拉线安装孔（4）、拉线（5）、充气/液管（6）、阀门（7）。由于袋壁（1）采用双层结构，含内层（1-1）、外层（1-2）、内层（1-1）与外层（1-2）的结合部（1-3）、以及内层（1-1）与外层（1-2）之间的气/液充填空间（1-4），可以通过充气/液管（6）向内层（1-1）与外层（1-2）之间的气/液充填空间（1-4）内充填气体或液体，使得袋壁（1）膨胀和坚硬起来；这样，袋壁（1）与纳入其中的切除组织标本之间有明显的分界线，袋壁（1）不会粘附在切除组织标本的表面上，方便用手术钳或破碎器在可张展型的內镜取物袋（100）内将切除组织标本破碎、取出，避免感染或癌细胞播种。

Description

內镜取物袋 技术领域
本发明涉及一种腔镜手术器械，特别是用于腔镜手术中将切除组织取出的內镜取物袋。
背景技术
随着腔镜技术的发展，越来越多的恶性肿瘤也在腔镜手术下完成。由于手术切除的恶性肿瘤有时较大，需要破碎后取出，破碎时容易发生癌细胞的播种、扩散；因此对于恶性肿瘤标本的取出，需要专门的器械。现有技术的內镜取物袋，袋壁粘附在标本组织上，用破碎器破碎组织标本时，容易导致取物袋破裂，造成泄漏，导致感染或癌细胞播种。因此需要对现有技术的內镜取物袋进行改进，以满足临床的需求。

具体实施方式
参考图1至图4，本发明之內镜取物袋100，含袋壁1、纳物空间2、开口端3、开口端拉线安装孔4、拉线5、充气/液管6、阀门7。
所述袋壁1采用双层结构，含内层1-1、外层1-2、内层与外层的结合部1-3、以及内层与外层之间的气/液充填空间1-4。
所述充气/液管6的远端连接所述内层与外层之间的气/液充填空间14，所述充气/液管6的近端连接所述阀门7；当所述阀门7打开时，可以通过所述阀门7向所述充气/液管6和所述内层与外层之间的气/液充填空间1-4充填气体或液体；当所述阀门7关闭时，所述内层与外层之间的气/液充填空间1-4与所述充气/液管6之间形成密闭的空间，气体或液体不会泄露。
所述拉线5可从所述开口端3上的开口端拉线安装孔4内穿过。
所述充气/液管6安装在靠近所述开口端3处，与所述袋壁1的内层1-1和外层1-2连接，并与所述内层与外层之间的气/液充填空间1-4形成密闭结构。
所述拉线5采用活结结构；当拉紧拉线时，可以收拢所述取物袋100的开口端3；当松弛所述拉线5时，能将所述取物袋100的开口端3再打开。
所述拉线5采用医用弹性材料丝或片制造。制造所述拉线5的医用弹性材料包括但不限于：医用金属弹性材料、医用高分子弹性材料，如医用弹性不锈钢丝、医用钛镍形状记忆合金丝、医用聚丙稀丝、医用尼龙丝等。
所述拉线5上设有滑块51，所述滑块51设有通孔51-1和线固定机构51-2；所述拉线5的一端固定在所述滑块51的上线固定机构51-2，另一端依次穿过所述开口端拉线安装孔4、以及所述滑块51的通孔51-1；所述拉线5可以在所述开口端拉线安装孔4和所述滑块51的通孔51-1内滑动，参考图2、图3。
所述袋壁1的内层与外层的结合部1-3采用热合方式或粘接方式连接在一起，参考图1至图4。以热合方式制造所述内层与外层的结合部1-3时，可以依据所述取物袋100的不同部位，设计不同的热合花纹，可以是圆形、椭圆形、方形、长方形、多边形，或其他的形状，在接近所述取物袋100的开口端3的部分，所述内层与外层的结合部1-3较少，方便所述内层与外层之间的气/液充填空间1-4形成环形的气囊或液囊，在人体切口外形成环形定位。而在所述取物袋100的中部或下部，由于要将所述取物袋100的袋壁1支撑起来，所述内层与外层的结合部1-3可以多些，使得所述内层与外层之间的气/液充填空间1-4形成格子形状的气囊或液囊，提高所述取物袋100的中部或下部的袋壁1的支撑力。
所述充气/液管6的远端通过热合方式或粘接方式与所述袋壁1的内层1-1及外层1-2连接在一起，并与所述内层与外层之间的气/液充填空间1-4接通。
所述充气/液管6的近端通过热合方式或粘接方式与所述阀门7连接在一起。
连接固定所述充气/液管6时，所述充气/液管6的远端可以与所述开口端3平行，也可以与所述开口端3垂直，主要依据所述取物袋100的深度来决定。如果所述取物袋100的深度较小，可以采用所述充气/液管6的远端与所述开口端3平行方式连接固定，方便将所述本发明之取物袋100递送到体内，参考图2、图3。如果所述取物袋100的深度较大，可以采用所述充气/液管6的远端与所述开口端3垂直方式连接固定，方便将所述本发明之取物袋100递送到体内，参考图1。此外，还可以将所述本发明之取物袋100压缩在鞘管9内，方便将所述本发明之取物袋100递送到体内，参考图6。
所述袋壁1的外层1-2的厚度比所述内层1-1的厚度大。这样，所述袋壁1的外层1-2的强度比所述内层1-1的强度大，即使是内层1-1在取出切除组织时发生破裂，所述外层 1-2仍然能起到良好的隔离防护作用，不会导致组织液的泄露或癌细胞的播种。
所述袋壁1的内层1-1和外层1-2采用高强度医用透明材料制造。制造本发明之內镜取物袋100的材料包括但不限于：医用PU薄膜、医用PE薄膜等。
所述取物袋100的边缘设有方便手术钳夹持的夹持环8，参考图5。所述夹持环8可用所述袋壁1的内层1-1和外层1-2热合后冲孔来制造。设立所述夹持环8，是为了方便手术钳夹持本发明之內镜取物袋100，通过穿刺器将其递送到体内。
所述取物袋100可以内置于方便通过穿刺器的鞘管9内，参考图6。将所述取物袋100压缩后内置于鞘管9内，是为了方便通过穿刺器，将本发明之內镜取物袋100释放在体内。
具体制造本发明之內镜取物袋100时，可以选择厚度在0.05mm的医用PU薄膜作为本发明之內镜取物袋100的袋壁的内层1-1的材料，选择厚度在0.08mm的医用PU薄膜作为本发明之內镜取物袋100的袋壁的外层1-2的材料，选择直径为3mm的PE管作为充气/液管6，购买大小合适的带阀门的医用两通作为阀门7。按照临床需要的內镜取物袋的大小，依据本发明的技术方案进行具体的产品设计，然后裁剪，并在专用热合机上热合，制造本发明之內镜取物袋100的热合边1-5，所述热合边1-5的大小，决定了本发明之內镜取物袋100的纳物空间2的大小；将所述拉线5从所述开口端3上的开口端拉线安装孔4内穿过；将所述充气/液管6的远端通过热合方式或粘接方式与所述袋壁1的内层1-1及外层1-2连接在一起，并与所述内层与外层之间的气/液充填空间1-4接通；将所述充气/液管6的近端通过热合方式或粘接方式与所述阀门7连接在一起，即得到了本发明之內镜取物袋。
临床使用时，先在腹壁13上做切口，插入穿刺器，然后通过穿刺器用手术钳将本发明之內镜取物袋递送到体内，或将本发明之內镜取物袋压缩后内置于所述鞘管9内，通过穿刺器后在体内释放。将切除的组织标本10放入本发明之內镜取物袋内后，向外拉动拉线5，在穿刺器鞘管的配合下，将本发明之內镜取物袋100的开口端3的袋口收拢；同时，向外向外退出穿刺器，一边拉紧拉线5，将所述內镜取物袋100的开口端3的袋口拉到所述腹壁13的切口外，然后再将伸出所述腹壁13外的本发明之所述內镜取物袋的开口端3的袋口重新打开；打开所述阀门7，向所述充气/液管6内注入气体或液体，使得本发明之所述內镜取物袋的袋壁1的内层与外层之间的气/液充填空间1-4内充适量的气体或液体，支撑起本发明之所述內镜取物袋的袋壁1；一方面在所述腹壁13外围绕所述腹壁13上的切口所述內镜取物袋100形成充气或液体的环形气囊，起到定位的作用；另一方面，在本发明之內镜取物袋的中部和下部的袋壁1因内层与外层之间的气/液充填空间1-4填充了充适量的气体而形成气囊，袋壁1的支撑力增加，形成气袋，将所述袋壁1与纳入的组织标本10 分离，方便对组织标本进行处理。这时，以所述腹壁13切口为界限，所述腹壁13上部的体外，本发明之內镜取物袋的上部形成环形开放端；所述腹壁13下部的体腔内，本发明之內镜取物袋的中下部形成密闭的气囊屋。被纳入的组织标本10可以在本发明之內镜取物袋的中下部形成的密闭的气囊屋内运动，方便对其进行处理、操作。同时，这种上端大、下端大、腹壁切口小的哑铃型气囊袋可以方便的将本发明之內镜取物袋固定在所述腹壁13上，方便器械的操作，不会移位，参考图4。
将所述将破碎器11置入所述取物袋100内，用抓钳12抓住所述组织标本10后，向外拉出组织标本10，通过所述破碎器11对所述组织标本10进行破碎并取出。所述组织标本10取出完毕后，将所述破碎器11从所述取物袋100内取出，打开所述阀门7，通过所述充气/液管6将充填的气体或液体排出后，轻拉所述取物袋100，将其从所述腹壁13的切口处取出体外。
由于所述组织标本10的整个破碎过程在所述取物袋100内完成，不会造成破碎过程中所述标本组织10飞溅至其他部位，可以有效避免组织液的泄露或癌细胞的播种，手术过程更加安全。
本发明之內镜取物袋，含袋壁1、纳物空间2、开口端3、开口端拉线安装孔4、拉线5、充气/液管6、阀门7。由于所述袋壁1采用双层结构，含内层1-1、外层1-2、内层与外层的结合部1-3、以及内层与外层之间的气/液充填空间1-4；可以通过所述充气/液管6向所述内层与外层之间的气/液充填空间1-4内充填气体或液体，使得袋壁1膨胀和坚硬起来；这样，所述袋壁1与纳入其中的切除组织标本之间有明显的分界线，所述袋壁1不会粘附在切除组织标本的表面上，方便用手术钳或破碎器在本发明之可张展型的內镜取物袋内将切除组织标本破碎、取出，避免感染或癌细胞播种。
应该注意，本文中公开和说明的结构可以用其它效果相同的结构代替，同时本发明所介绍的实施例并非实现本发明的唯一结构。虽然本发明的优先实施例已在本文中予以介绍和说明，但本领域内的技术人员都清楚知道这些实施例不过是举例说明而己，本领域内的技术人员可以做出无数的变化、改进和代替，而不会脱离本发明，因此，应按照本发明所附的权利要求书的精神和范围来的界定本发明的保护范围。
