Description
技术领域
本发明的主题是一种用于减肥外科手术，特别是套筒式胃切除术中的医疗用途的胃管。
背景技术
现有技术的胃管以弹性或刚性管的形式，通过鼻或腹部插入患者的胃或肠中，特别是以使人能够食入。肠内营养是营养治疗的形式，其包括通过非口服途径将营养物质、水、蛋白质、电解质和微量元素输送到胃肠道(GI)腔内。这种管可用于胃食管反流恶化、胃轻瘫、重症监护室患者(因为它允许使用药物)，具有严重创伤、慢性肠麻痹风险以及具有严重急性胰腺炎。这种类型的管有多种尺寸。
现有技术还描述了一种用于洗胃以从胃中除去毒物或有毒物质的宽管。只有在摄入强毒素后不到一小时的时间内洗胃才是有效的。如果是药物，特别是长时间释放的药物，在摄入后4小时内洗胃是有效的；并且在摄食鹅膏伞形毒蕈(Amanita phalloides，俗称死亡帽菇)的情况下，如果在10小时或更长时间内执行洗胃，该方法是有效的。在使用利多卡因润滑后，将管插入胃中，然后用注射器或漏斗送入0.45％的NaCl水溶液，该水溶液流经胃管进入胃中。一段时间后，管端降至患者的身体水平以下，这导致胃的内容物流出。重复该过程直到获得清澈的洗胃液。
现有技术还描述了一种用于外科手术、特别是用于腹腔镜套管式胃切除术的胃管。这种手术包括切除3/5的胃。该管是弹性导管的形式，该弹性导管通过嘴插入患者胃的前幽门段，然后通过操纵器械沿着胃的较小曲率放置。在手术过程中，胃的左侧部分被切掉，并沿着管造成切口。此类手术常规使用的管没有照明。由于在手术过程中能见度有限，因此当用内吻合器(endostapler)切除胃部时有造成管损伤的风险。相关的并发症可能威胁患者的生命。切除完成后，经由导管送入甲基蓝，以便测试胃壁是否有渗漏。测试结束后，染料通过管被抽取出来。
本实用新型申请W.126183描述了一种LED照明的胃管，其特别适用于腹腔镜套管式胃切除术中。类似于常规使用的管，该管具有弹性管的形式，但是具有LED照明。所述胃管的管壁内放置有LED。照明可以沿着管的整个长度安装，或者只安装在远段。LED照明有助于将管定位在患者的腹部，因为光通过患者的胃壁投射。该管还可用于外科手术后的胃减压和渗漏测试。
由诸如PVC、硅氧烷或聚氨酯之类的塑料制成的管，在本领域中是众所周知的。
现有技术的非照明胃管在手术过程中不能保护胃管不受损伤。根据现有技术的照明的胃管在管壁内嵌入LED以及在二极管电源线的布置方面难以实现。
本发明的目的是避免已知胃管的缺点，并提供可安全用于在减肥手术中使用的新型胃管。
发明内容
根据本发明的用于减肥手术的胃管是透明塑料管制成的导管形式，其中置于导管内的胃管配备有照明外表面的光纤，其具有置于胃管部分中用于插入患者胃中的内端部，以及用于与光源连接的外端部，该外端被设置在胃管的外侧且位于胃管的保持在患者的身体外侧的部分中。胃管的导管在其内部包括第一通道和第二通道，第一通道作为传输通道，光纤位于第二通道中。
优选地，光纤具有沿其整个长度的照明表面。
可选地，光纤的照明表面优选地仅存在于内端部处的远端部分中。
优选地，光纤也仅在内端部处的远端部分中具有照明表面，并且光纤的外表面在该部分中具有凹口。
优选地，光源与电源适配器连接。
优选地，光源还可以由可充电电池供电。
附图说明
现在参照附图来说明本发明的主题，其中图1示出了放大的胃管近端和远端部分；图2示出了插入患者体内的胃管；图3示出了插入患者胃中的胃管的远端部分；图4是胃管沿图1所示AA线的剖面图。
根据本发明的胃管1旨在用于减肥外科手术中，特别是作为肥胖治疗过程中的套筒式胃切除术使用。
具体实施方式
在图1、2和3所示的实施方式中，胃管1是由塑料制成的弹性管状的透明导管2的形式，并且配备有通过其外表面发光的光纤3。光纤3的内端部4被放置在胃管1部分中，用于插入患者胃8中，以及旨在用于与光源连接的光纤3的外端部5，该外端部被设置在胃管1的外侧且位于胃管1的保持在患者的身体外侧的部分。胃管1的导管2在其内部包括第一通道21和第二通道22，第一通道21作为传输通道，光纤位于第二通道22中。
图4中所示的管道2具有圆形剖面，并且第一通道21和第二通道22通过与导管2相同外壁材料的内壁11隔开。在该实施方式中，第一通道21的剖面等于第二通道22的剖面。
在图1、图2和图3所示的实施方式中，光纤3具有沿着其整个长度的照明表面。而且，在光纤3的内端部4的端部部分，该部分中的光纤3的外表面具有凹口6，该凹口可增强从光纤3的侧表面发射的光。
显然，在其它实施方式中，胃管1可以配备有仅在光纤3的内端部4处的远端部分具有照明表面的光纤3。
为了使纤维胃管1的光纤3发射光，需要将光纤3连接到光源。这通过光纤3的外端部5来实现的。光源与电源适配器连接。或者，光源可以由可充电或不可充电的电池供电。
在图1和3所示的实施方式中，胃管1的第二通道22从顶部封闭，光纤3经由在导管2上部部分中的导管2的外壁上的开口引入第二通道22。光纤3的外端部5保留在导管2的外侧，以及其内端部4延伸到第二通道22的远端、下部端。远端端部的第一通道21和第二通道22以本领域公知的方式封闭(被封盖)。第一通道21和第二通道22在远端端部的封盖使得光纤3的内端部4固定不动。第一通道21从顶部打开。在胃管1的远端部分，作为输送通道的第一通道21的导管2的外壁具有两个圆形的输送开口7。第一通道21是贯通通道，并且可以用于将液体输送到胃8并从胃8中抽出，而光纤3通过导管2的侧壁被引入到第二通道22，该第二通道22从顶部和从底部封闭，并通过内壁11与第一通道21隔开。
在腹腔镜套管式胃切除术过程中，胃管1通过嘴和食管被引入患者胃8的前幽门段。在该过程中，用外科器械操纵胃管1，以使其平行对齐于胃8的较小曲率10。在该过程中对胃管1的照明有助于发现在胃8内胃管1的位置，这又降低了胃管1由于例如利用内吻合器进行切除而损伤的风险，该风险可能导致患者的并发症。如图3所示，在胃血管夹持之后，大约85％的胃8被切除，并且沿着线9(其沿着胃管1延伸并位于胃管1附近)进行切除。切除是使用内吻合器进行的，即使用缝合器将患者胃1的剩余部分的边缘接合起来的外科器械。当胃8切除完成时，将甲基蓝通过胃管1的第一通道21输送到患者胃8的剩余部分，以便测试胃8壁是否有泄漏。当测试完成时，染料经由传输开口7被抽取，并通过第一通道21从患者的胃8中吸出。
