背景技术
胃管是一种能够连通胃部和人体外部环境的导管，用于将必要的水分和营养物质直接输送至胃部，或者将胃内容物和胃内积气及时排出。在一些腹部外科手术中需要留置胃管，然而，插入胃管的过程存在风险。
具体地，在手术过程中，胃管从鼻腔或者口腔经过咽部进入食道，进而沿着食道被插入并留置于胃部。食道入口和气道入口相邻，在插入胃管的过程中，胃管很可能误入气道，造成患者胸闷、气短、呼吸困难、呛咳等。
更具体地，一方面，胃管是在不可视的情况下被插入至人体中的，在手术过程中，主要依赖于操作者的经验将胃管准确地插入食道，进而进入胃部，如果操作者判断有误，则可能将胃管插入气道。且在不可视的情况下，胃管在行进过程中可能损伤人体通道(例如，鼻腔、气道)的内壁。
另一方面，胃管不可自主弯曲，在其行进过程中，主要通过人体通道的内壁对其施加的外力和操作者对其施加的外力来实现弯曲，进而调整其行进方向。人体通道的内壁对胃管的行进方向的控制有限，特别是到达食道和气道的分叉口处时，仅依靠人体通道的内壁对胃管的外力作用不足以判断胃管的正确行进方向。操作者对胃管的施力点位于人体外部，距离胃管的进入人体内部的端部较远，对胃管的进入人体内部的端部的行进方向的控制极其有限，这增加了胃管准确进入食道的难度。
再者，在插入胃管的过程中，当进管操作和患者的吞咽动作不协调时，患者的咽喉会对胃管产生阻力，进一步增加胃管的进管难度，还可能导致患者恶心、呕吐。
因此，需要一种胃管进管方案，以使得胃管能够准确地被插入食道。
胃部检查或胃部检查后的治疗工作往往需要将检查管或者治疗用的设备送至于肠胃内部。由于鼻腔后端有两个通道通向不同的器官，因此，最初管子的插入需要依靠医生的经验去判断送管过程中的位置，以防将管子送错位置，这样不仅对患者的身体造成一定伤害，而且也增加了患者的身体痛苦。
另外，现有技术中，就算将管子正确地送至胃部，由于管子通常需要在患者体内的操作位置处保持较长时间，因此，如何确保这种管子的插入、定位和锚定要对于患者来说尽可能地舒适是很重要的，同时要确保该管子不会意外地从患者体内移除。
同时，对胃部进行检查或治疗往往也伴随着需要对胃部的内容物进行抽取或/和对胃部进行清洗，而胃部的内容物中残留成分比较复杂，当中经常包括未消化完全的食物残渣，因此在抽取过程中容易出现堵塞现象，不仅会影响对胃部的检查、清洗或治疗工作，也增加患者在胃部内容物被抽取过程中的风险和痛苦。

具体实施方式
下面，将参考附图详细地描述根据本申请的示例实施例。显然，所描述的实施例仅仅是本申请的一部分实施例，而不是本申请的全部实施例，应理解，本申请不受这里描述的示例实施例的限制。
申请概述
如前所述，胃管是一种能够连通胃部和人体外部环境的导管，用于将必要的水分和营养物质直接输送至胃部，或者将胃内容物和胃内积气及时排出。在一些腹部外科手术中需要留置胃管，然而，插入胃管的过程存在风险。
具体地，在手术过程中，胃管从鼻腔或者口腔经过咽部进入食道，进而沿着食道被插入并留置于胃部。食道入口和气道入口相邻，在插入胃管的过程中，胃管很可能误入气道，造成患者胸闷、气短、呼吸困难、呛咳等。
更具体地，一方面，胃管是在不可视的情况下被插入至人体中的，在手术过程中，主要依赖于操作者的经验将胃管准确地插入食道，进而进入胃部，如果操作者判断有误，则可能将胃管插入气道。且在不可视的情况下，胃管在行进过程中可能损伤人体通道(例如，鼻腔、气道)的内壁。
另一方面，胃管不可自主弯曲，在其行进过程中，主要通过人体通道的内壁对其施加的外力和操作者对其施加的外力来实现弯曲，进而调整其行进方向。人体通道的内壁对胃管的行进方向的控制有限，特别是到达食道和气道的分叉口处时，仅依靠人体通道的内壁对胃管的外力作用不足以判断胃管的正确行进方向。操作者对胃管的施力点位于人体外部，距离胃管的进入人体内部的端部较远，对胃管的进入人体内部的端部的行进方向的控制极其有限，这增加了胃管准确进入食道的难度。
再者，在插入胃管的过程中，当进管操作和患者的吞咽动作不协调时，患者的咽喉会对胃管产生阻力，进一步增加胃管的进管难度，还可能导致患者恶心、呕吐。
因此，需要一种胃管进管方案，以使得胃管能够准确地被插入食道。
理论上讲，为了使得胃管能够准确地进入食道，可在胃管上设置可视化设备和用于实现可控弯曲的部件，然而，这可能影响胃管输送水分和营养物质或者导出内容物，且在输送水分和营养物质或者导出内容物的过程中可能影响可视化设备和用于实现可控弯曲的部件的性能。
本申请的发明人提出，目前，在插入胃管的操作中，胃管在到达食道和气道的分叉口时需要在不可视的条件下选择进入食道或者气道，如果在胃管行进过程中周围的环境仅允许胃管进入食道，那么，胃管无需进行选择即可进入食道。
基于此，本申请提出可为胃管创造这样的环境——仅允许胃管进入食道，这样，可以为胃管提供准确的进入食道的路径，使得胃管能够沿着进入食道的准确路径准确地进入食道。
示意性可视胃管进管装置
如图1至图11所示，根据本申请实施例的可视胃管进管装置1被阐明。所述可视胃管进管装置1包括一辅助管10和设置于所述辅助管10的一可视导引件20。所述辅助管10包括一导引通道101，所述可视导引件20包括置于所述导引通道101内的一导引管体21和设置于所述导引管体21的一摄像设备22，如图1所示。所述摄像设备22可电连接于人体外的显示设备，以使得操作者在可视的条件下导引所述辅助管10准确地进入食道E，为胃管2创建进入食道E的准确路径，进而使得胃管2能够顺利到达胃部。
具体地，所述辅助管10和所述可视导引件20准确地进入食道E后，所述辅助管10的导引通道101或者设置于所述可视导引件20的通道(例如，后文提及的第一通道201、第二通道202)可为胃管2提供进入食道E的准确路径，使得胃管2无需对进入气道P或者食道E做出选择，只要沿着所述可视胃管进管装置1创建的进入食道E的准确路径即可准确地进入食道E，进而进入胃部。
应可以理解，用于容纳胃管2以为胃管2提供进入食道E的路径的通道的径向尺寸应大于等于胃管2的外径尺寸。如果以所述辅助管10的导引通道101作为直接容纳胃管2的通道，即，胃管2无需借助所述导引通道101中的其他部件(例如，所述可视导引件20)保持于所述导引通道101中，而是被直接置于所述导引通道101中，所述辅助管10的径向尺寸需大于所述胃管2的径向尺寸即可。如果以所述可视导引件20的通道作为容纳所述胃管2的通道，所述辅助管10的径向尺寸需大于所述胃管2的径向尺寸与所述可视导引件20的用于容纳所述胃管2的通道之外的部分占用的径向尺寸之和。
也应可以理解，较小的径向尺寸有利于所述可视胃管进管装置1进入患者体内，减轻患者在所述可视胃管进管装置1进入体内的过程中的不适，降低操作风险。为了缩减所述辅助管10的径向尺寸，优选地，以所述辅助管10的导引通道101作为直接容纳胃管2的通道。
相应地，在本申请实施例中，所述可视导引件20被设计为可拆卸地设置于所述辅助管10，以使得所述可视胃管进管装置1在所述辅助管10留置于食道E且所述可视导引件20被拆离所述辅助管10后允许胃管2沿所述辅助管10的导引通道101进入食道E，使得胃管2即使在不可视的条件下也能够准确地进入食道E。也就是，可以在可视的条件下为所述胃管2预先铺路，使得所述胃管2在不可视的条件下也可以顺利进入食道E，进而进入胃部。如图4所示，胃管2可拆卸地置于所述辅助管10的导引通道101内。所述胃管2沿所述辅助管10的导引通道101进入所述食道E或者胃部后，所述辅助管10可被撤离所述胃管2，并从患者的体内退出。
值得一提的是，在本申请实施例中，所述可视胃管进管装置1为胃管2提供进入食道E的准确路径的同时，还形成了人体通道的保护层，避免胃管2进入食道E的过程中刮、划到人体通道的内壁，对人体通道造成损伤。所述可视胃管进管装置1不仅能够为胃管2提供进入食道E的准确路径，还允许其他形状、尺寸合适的器械通过，可以为其他经过食道E的器械提供便利。
在本申请实施例中，所述辅助管10具有相对的第一端部1010和第二端部1020，所述导引通道101从所述第一端部1010延伸至所述第二端部1020。所述可视导引件20的导引管体21具有相对的前端部2101和后端部2102，所述导引管体21的前端部2101是指在实际操作过程中进入人体内部的一端，所述导引管体21的后端部2102在实际操作过程中可留在人体外部，且所述可视导引件20进一步包括连接于所述导引管体21的后端部2102的操控部23，以便于操作者操作。当所述可视导引件20置于所述辅助管10的导引通道101内时，所述导引管体21的前端部2101邻近于所述导引通道101的第一端部1010，所述导引管体21的后端部2102邻近于所述导引通道101的第二端部1020。
为了保持所述可视导引件20置于所述辅助管10的导引通道101内时，所述可视导引件20和所述辅助管10之间的位置关系的稳定性，在本申请的一些实施方式中，所述可视导引件20和所述辅助管10之间设置有相互适配的锁定结构，使得所述可视导引件20能够稳定地安装于所述辅助管10。所述锁定结构被解锁后，所述可视导引件20可拆离所述辅助管10。在本申请的一个具体示例中，所述可视导引件20设有位于导引管体21的后端部2102的外螺纹，所述辅助管10的第二端部1020设有位于所述导引通道101内壁的适配于所述导引管体21的外螺纹的内螺纹，所述外螺纹和所述内螺纹形成所述锁定结构。在本申请的其他具体示例中，所述可视导引件20和所述辅助管10之间的锁定结构可被实施为其他结构。
进一步地，所述导引管体21包括至少一可弯曲部2103，如图2所示。优选地，所述辅助管10的至少一部分由柔性材料制成，所述可视导引件20的可弯曲部2103的硬度大于等于所述辅助管10的与所述可弯曲部2103对应的部分的硬度，所述可视导引件20的邻近于所述可弯曲部2103的部分的硬度也大于等于所述辅助管10的与其(即，所述可视导引件20的邻近于所述可弯曲部2103的部分)对应的部分的硬度，以在所述导引管体21的可弯曲部2103发生弯曲的同时带动所述辅助管10弯曲(如图3所示)。
所述导引管体21可整体形成所述可弯曲部2103，也可局部形成所述可弯曲部2103。优选地，所述可弯曲部2103形成于所述导引管体21的邻近于所述前端部2101的部分，或者，所述导引管体21的临近于所述后端部2102的部分。
所述操控部23包括可操作地连接于所述可弯曲部2103的第一控制件231，所述第一控制件231被配置为控制所述可弯曲部2103弯曲预设角度，以使得所述导引管体21和所述辅助管10实现可控、准确的弯曲。如图6所示，
特别地，人体的气道和食道的位置是确定的，气道和食道的分叉口处的人体通道与所述食道之间的偏转角度是确定的。这意味着，沿着人体通道进入气道和食道的分叉口处的导引管体21进入食道E需要偏转的角度也是确定的。 也就是，当所述导引管体21到达气道和食道的分叉口处时，操作者将所述导引管体21的可弯曲部2103调节至预设弯曲度即可使得所述导引管体21进入食道，无需反复调试弯曲角度，这无疑简化了控制过程。
在实际操作中，操作者在患者体外操作所述第一控制件231即可控制位于患者体内的弯曲部2103的弯曲预设角度，使得所述导引管体21和所述辅助管10在可视的条件下更加容易、快速且准确地进入食道E，还可以有效避免在行进过程中损伤人体通道的内壁。
所述导引管体21的可弯曲部2103实现弯曲的具体实施方式并不为本申请所局限。在本申请的一个具体示例中，所述可弯曲部2103包括一医用蛇骨管，所述医用蛇骨管包括形状类似骨节且相互锁合的多个骨节部，多个骨节部之间具有间隙，使得所述多个骨节部可以相对活动，以此来实现弯曲。相应地，所述可视导引件20还包括形成于所述可弯曲部2103和所述第一控制件231之间的至少一牵引线，所述第一控制件231被实施为被所述牵引线缠绕的滚轮，操作者通过转动所述滚轮(即，第一控制件231)可旋紧或放松所述牵引线，以控制所述可弯曲部2103的弯曲角度和/或弯曲方向，也可通过转动所述可视胃管进管装置1可调整所述可弯曲部2103相对于人体通道的弯曲方向。
在本申请的另一个具体示例中，所述可视导引件20还包括连接于所述牵引线的一驱动器，所述第一控制件231被实施为电连接于所述驱动器的按压式部件，操作者通过按压所述第一控制件231可控制所述牵引线的旋紧或放松，以控制所述可弯曲部2103的弯曲角度和/或弯曲方向。在本申请的其他具体示例中，所述可弯曲部2103和所述第一控制件231可被实施为其他类型的部件，所述可弯曲部2103和所述第一控制件231之间的控制方式也可被实施为其他方式。
在本申请实施例中，所述辅助管10的主要作用在于为胃管2提供进入食道E的准确路径，所述辅助管10的长度大于等于患者的鼻腔或者口腔与患者的食道E入口之间的人体通道的长度即可。而所述导引管体21不仅可用于导引所述辅助管10在可视的条件下进入食道E，还可到达胃部，用于导出胃部的异物或气体，或者为其他器械从食道E进入胃部提供路径。
因此，优选地，所述导引管体21的长度大于等于所述导引通道101的长度，使得所述导引管体21的前端部2101伸出所述导引通道101，更灵活地在患者的胃部内活动。相应地，所述导引管体21的长度大于等于鼻腔或者口腔与患者的胃部入口之间的人体通道的长度。也就是，所述辅助管10和所述可视导引件20的导引管体21可设计为短辅助管10、长导引管体21的配置，即，所述辅助管10较短，所述导引管体21较长。所述导引管体21的后端部2102固定于所述辅助管10，所述导引管体21的前端部2101伸出所述辅助管10的导引通道101后进入胃部进行吸引、冲洗等操作，之后，所述可视导引件20可退出，胃管2可置入所述辅助管10的导引通道101中，使得所述胃管2沿着所述辅助管10的导引通道101进入食道E，进而进入胃部。
当然，所述辅助管10和所述可视导引件20的导引管体21也可设计为短辅助管10、短导引管体21的配置。即，所述辅助管10和所述导引管体21均较短。所述可视导引件20的导引管体21的长度大于等于患者的鼻腔与患者的食道E入口之间的人体通道的长度，将所述辅助管10导引至食道E即可，无需伸入至胃部进行吸引、冲洗等操作。具体地，可将所述可视导引件20的导引管体21的中部固定于所述辅助管10，所述视导引件20将所述辅助管10导引至食道E后可退出，胃管2可置入所述辅助管10的导引通道101中，使得所述胃管2沿着所述辅助管10的导引通道101进入食道E，进而进入胃部。
在本申请实施例中，所述导引管体21进一步包括延伸于所述前端部2101和所述后端部2102之间的第一通道201。所述第一通道201可作为吸引通道，以负压吸引的方式导出胃部内的异物(例如，混杂液体、食物残渣)或气体，所述操控部23还包括连通于所述第一通道201的控制孔232，以控制所述第一通道201内的压力。在实际操作中，操作者可通过按压或松开所述控制孔232控制所述第一通道201内的压力。
所述第一通道201具有形成于所述导引管体21的前端部2101的第一开口，优选地，所述第一开口在所述摄像设备22的视场范围内，以在可视的条件下对胃部内的异物或者气体进行吸引，以保证患者的安全。在本申请的一个具体示例中，所述导引管体21具有一前端面，且所述前端面与所述导引管体21的径向成夹角，与所述导引管体21的轴向的夹角小于90度，从所述导引管体21的外周壁的第一侧部向后延伸至所述导引管体21的外周壁的与所述第一侧部相对的第二侧部。所述第一开口和所述摄像设备22形成于所述导引管体21的前端面，所述摄像设备22位于所述第一开口的后方，且朝向所述第一开口，以使得所述第一开口位于所述摄像设备22的视场范围内。
在本申请的一些实施方式中，所述第一通道201还可以作为冲水通道，向胃部冲水(或者其他流体)，以冲击胃部的异物(例如，混杂液体、食物残渣)，所述操控部23还包括连通于所述第一通道201的第一连通口，以向所述第一通道201供水。所述第一通道201还可以作为容纳其他器械(例如，光纤)的通道。
在实际操作过程中，在需要吸引胃部异物时可将所述第一通道201用作吸引通道，需向胃部冲水时停止吸引操作，通过所述第一连通口向所述第一通道201供水，需向胃部递送其他器械时，可停止吸引操作或者冲水操作，从所述第一连通口或者位于所述操控部23且连通于所述第一通道201的连通口(例如，第二连通口)插入其他器械。
在本申请的一些实施方式中，如图2所示，所述第一通道201作为专门用于吸引的吸引通道，所述导引管体21还具有第二通道202，可以用作冲水通道或者容纳其他器械的通道，以避免对吸引过程造成干扰，同时，减少各个操作之间的切换过程，简化手术过程，节约手术时间。
在实际操作中，在通过所述第一通道201实现吸引的过程中，可通过所述第二通道202实现冲水，或者，通过被容置于所述第二通道202的器械完成其他操作。
值得一提的是，当吸引和冲水同时进行时，冲水过程容易被来自所述第一通道201的负压吸引所干扰，具体表现为，水流从所述第二通道202冲出后可能受到所述第一通道201的负压吸引，在未到达目标位置时被吸引回流至所述第一通道201，这样，难以实现对胃部的有效冲洗。
本申请的发明人发现，可通过调节所述第一通道201和所述第二通道202的开口的相对位置关系来控制负压吸引对冲水过程造成的干扰。具体地，所述第二通道202具有形成于所述导引管体21的前端部2101的第二开口，设计所述第二开口的朝向和所述第一开口的朝向不一致，通过这样的方式使得所述第一通道201的第一开口与所述第二通道202的第二开口相互隔离，进而减弱负压吸引对冲水过程造成的干扰。
相应地，在本申请的一个具体示例中，如图6所示，所述第一开口和所述第二开口设置于所述导引管体21的前端部，其中，所述第一开口设置于所述导引管体21的前端面，所述第二开口设置于所述导引管体21的外周壁，通过这样的方式使得所述第二开口的朝向和所述第一开口的朝向不一致。这样，流体从所述第二通道202的第二开口沿特定方向被出射后需要发生偏转才能绕行至所述第一通道201的第一开口，也就是，流体从所述第二通道202的第二开口出射被沿特定方向出射后沿着与所述特定方向成夹角的方向回流至所述第一通道201的第一开口，并非沿着与所述特定方向相反的方向之间回流至所述第一通道201的第一开口，可以减弱负压吸引对冲水过程造成的干扰。
值得一提的是，所述第一开口和所述第二开口分别布置于所述导引管体21的不同面(即，存在夹角的面)，所述第一开口和所述第二开口互不占用各自开口所在面的空间，所述第一开口和所述第二开口的尺寸设计也可更为灵活。
在冲水和吸引过程中，所述第一通道201作为吸引通道，以负压吸引的方式导出胃部内的异物(例如，混杂液体、食物残渣)，相应地，所述第一通道201的第一开口的内径尺寸应较大，以避免发生堵塞。所述第一开口和所述第二开口布置于所述导引管体21的不同面，为所述第一开口提供了足够的布设空间。所述第二通道201作为冲水通道，主要用于出射用于冲洗胃部的流体，不太容易发生堵塞，所述第二开口的内径尺寸可相对较小，也就是，所述第一开口的内径尺寸大于所述第二开口的内径尺寸。
当然，所述第一开口和所述第二开口也可以其他方式布置。在本申请的另一个具体示例中，所述第一开口和所述第二开口均设置于所述导引管体21的前端面，所述第一通道201的邻近于所述第一开口的部分的纵中心轴与所述第二通道202的邻近于所述第二开口的部分的纵中心轴呈夹角，以使得所述第二开口的朝向和所述第一开口的朝向不一致，可以减弱负压吸引对冲水过程造成的干扰。
下面将对所述可视胃管进管装置1的实际应用过程进行介绍。
在实际操作中，首先，将所述可视导引件20置于所述可视胃管进管装置1的辅助管10的导引通道101内。
接着，将所述可视胃管进管装置1的辅助管10和置于所述辅助管10的导引通道101内的可视导引件20一起从患者的鼻腔或者口腔插入患者体内，在可视化的条件下进入咽喉到达食道E。
在所述可视胃管进管装置1在可视化的条件下进入咽喉到达食道E的过程中，所述可视胃管进管装置1先从患者的鼻腔或者口腔沿着人体的天然通道进入至食道E和气道P的交叉口处，如图7所示；然后，在可视的条件下控制所述可视导引件20的可弯曲部2103弯曲预设角度，进而带动所述辅助管10弯曲，以使得所述辅助管10和所述可视导引件20在可视化的条件下从食道E和气道P的交叉口处较为容易、快速且准确地进入食道E，如图8和图9所示。
随后，将所述可视导引件20从所述辅助管10的导引通道101撤离，如图10所示。值得一提的是，在将所述可视导引件20从所述辅助管10的导引通道101撤离之前，可将所述可视导引件20在可视的条件下根据实际应用需求利用所述可视导引件20对胃部进行吸引、冲水等操作。
最后，将胃管2插入所述可视导引件20的导引通道101(如图11所示)，以使得所述胃管2沿所述导引通道101在不可视的条件下准确地进入食道，进而进入胃部。所述胃管2进入胃部后，操作者可通过所述胃管2向患者输送必要的水分和食物。
值得一提的是，在一些实施方式中，将胃管2置于胃部后，所述辅助管10可从人体撤离。具体地，在本申请的一具体示例中，所述辅助管10可设置为可撕型辅助管，所述辅助管包括从所述辅助管10的第一端部1010延伸至所述辅助管10的第二端部1020的第一侧部和从所述辅助管10的第一端部1010延伸至所述辅助管10的第二端部1020的第二侧部，所述第一侧部可分离地设置于所述第一侧部，所述第一侧部和所述第二侧部在外力作用下可彼此分离。为了便于所述第一侧部和所述第二侧部相互分离，可在所述第一侧部设置从所述第一侧部向外延伸的第一作用部，和/或，在所述第二侧部设置从所述第二侧部向外延伸的第二作用部，所述第一作用部和所述第二作用部可形成于所述辅助管1020的后端部，以便于操作者操作。在胃管2置于胃部后，可在所述辅助管1020的后端部通过所述第一作用部和所述第二作用部对所述辅助管10的第一侧部和第二侧部分别提供向外侧的作用力，将所述第一侧部和所述第二侧部分离，并将所述第一侧部和所述第二侧部抽离人体，通过这样的方式将所述辅助管10可从人体撤离。
在本申请的另一具体示例中，所述辅助管10的最小径向尺寸大于所述胃管的最大径向尺寸，将胃管2置于胃部后，所述辅助管10可从所述胃管2抽离，通过这样的方式将所述辅助管10从人体撤离。
综上，基于本申请实施例的所述可视胃管进管装置1被阐明，所述可视胃管进管装置1能够在可视的条件下准确地进入食道E，以为胃管2提供进入食道E的准确路径，使得胃管2即使在不可视的条件下也能够准确地进入食道E。
本发明提供一种经鼻疏通吸引装置910，用于对胃部的内容物进行疏通吸引，如图12至图15所示，为本发明所述的经鼻疏通吸引装置910的第一实施例的结构示意图。所述经鼻疏通吸引装置910包括至少一可视化组件912和一导入元件911，其中所述可视化组件912被设置为与所述导入元件911可拆卸式连接且所述导入元件911能够在所述可视化组件912的可视化协助下将所述可视化组件912从患者的鼻腔导入插置于患者的胃部，其中所述可视化组件912包括至少一吸引元件91221，所述吸引元件91221能够将胃部内容物吸引出来。
详细而言，在本发明的第一实施例种，所述导入元件911被实施为一鞘9111，所述鞘9111为柔性材料制成且所述鞘9111的外表面具有顺滑表层，从而使所述鞘9111能够顺滑通过患者鼻腔进入食道，并且在食道中根据实际情况进行弯曲，进而将所述可视化组件912输送进入患者食道。
所述可视化组件912包括至少一控制元件9121和一可视元件9122，其中所述可视元件9122包括所述吸引元件91221，所述吸引元件91221被设置为一中空管件912211，所述中空管件912211具有一通道9122110并包括一进入端9122111和一控制端9122112，所述进入端9122111进入患者的体内，所述控制端9122112位于患者的体外，所述控制元件9121被设置于所述中空管件912211的所述控制端9122112并能够控制所述中空管件912211的运动，所述可视元件9122被设置于所述中空管件912211的所述进入端9122111，从而使所述可视元件9122能够跟随所述中空管件912211一起进入患者体内。
所述可视元件9122进一步包括至少一可视光纤91222，所述可视光纤91222被设置于所述中空管件912211的所述进入端9122111，从而使所述可视元件9122进入患者胃部后具有可视效果。
换言之，在本发明的第一实施例中，所述可视元件9122具有一通道9122110而形成所述吸引元件91221，所述吸引元件91221随着所述可视元件9122而进入患者胃部，并完成对患者胃部内容物的吸出。
由于所述鞘9111的顺滑表层的作用，因此所述可视元件9122能够被所述中空管件912211带动并在所述鞘9111的输送下进入患者体内，而一旦进入患者体内后，由于所述可视元件9122的可视效果，因此操作人员可以在所述可视元件9122的可视化作用下通过所述控制元件9121控制所述鞘9111和所述中空管件912211的运动方向，从而控制所述鞘9111和所述中空管件912211避开患者的气道，顺利从患者的鼻腔进入患者的食道。
所述鞘9111将所述中空管件912211输送进入患者的食道后，所述鞘9111即可从患者的体内抽离，因为食道与胃部直接连通且中间并没有其他分支。在本发明的第一实施例中，所述鞘9111被实施为可拆卸结构，当所述中空管件912211被所述鞘9111导入患者食道后，即可将所述鞘9111拆卸而抽离于患者食道。
同时，由于所述可视元件9122被设置于所述中空管件912211的所述进入端9122111被带进入了患者体内，因此所述可视元件9122能够将所述中空管件912211的行程路径及时反馈给操作人员，操作人员根据所述可视元件9122提供的影像通过所述控制元件9121控制所述中空管件912211的移动方向，进而使所述中空管件912211能够顺利进入患者胃部。
需要强调的是，所述控制元件9121包括一方向控制模块91211，所述方向控制模块91211被可控制地连接于所述所述中空管件912211以通过所述方向控制模块91211控制所述中空管件912211的运动包括移动方向和移动速度等。
所述中空管件9122211被可控制地连接于所述方向控制模块91211并且所述中空管件9122211被设置为可弯曲的，并且能够被连接于一负压吸引设备，以在胃部进行负压吸引。详细地说，所述中空管件9122211可以包括一三层结构，内层、外层和中间层，其中所述中间层可以起到支撑作用，所述外层和所述内层可以被设置为较为柔软的。所述中空管件9122211可以被设置为被动弯曲的，换句话说，跟随一物品弯曲而弯曲。所述中间层可以被设置为一弹簧圈结构。
所述中空管件9122211包括一前部管件和一后部管件，所述前部管件相对于所述后部管件可以转动至某一角度从而使得整个所述中空管件9122211形成弯曲。所述前部管件和所述后部管件分别包括部分所述外层、部分所述中间层和部分所述中间层。值得注意的是，所述中间层在所述后部管件被布置的相对致密，在所述前部管件保持相对疏松，以使得所述中空管件9122211能够在所述前部管件和所述后部管件的连接处位置弯曲并且保持管内空间，并且在负压吸引的情况下可以保持通畅。换言之，藉由弹簧圈的支撑作用，所述中空管件9122211可以在弯曲状态时保持整个管件不被压扁，并且在负压吸引的情况下，也可以维持整个管体的形态，从而使得体内的物体仍然可以通畅地经过。
所述外层和所述内层可以对于所述中间层起到保护作用，可以是光滑的涂层，也可以是树脂材料等。另外，所述外层、所述中间层以及所述内层可以是一体的成型的。在所述中间层的基础上直接注塑形成所述外层和所述内层。所述外层、所述中间层以及所述内层也可以是分体形成的，比如说在分别形成所述中间层、所述外层和所述内层之后，三者可以压制成所述中空管件9122211。本领域技术人员当然可以理解的是，上述的所述中空管件9122211的制造方式为举例说明，并不意味着对于本发明的限制。
在本发明的第一实施例中，所述中空管件912211被设置为一柔性管件，所述中空管件912211能够被输送至患者胃部，且患者胃部的内容物能够通过所述中空管件912211被吸引至外部，从而方便对患者胃部进行检查、清洗或治疗。
所述控制元件9121进一步包括一吸收控制模块91212，所述吸收控制模块91212被可控制地与所述中空管件912211连接以用于控制所述中空管件912211对胃部的内容物进行吸收。当所述中空管件912211到达患者的胃部且所述中空管件912211的所述进入端9122111被浸没于胃部的内容物时，操作人员通过所述控制元件9121的所述吸收控制模块91212控制所述中空管件912211对胃部内容物进行吸收。
如图14所示，本发明所述的经鼻疏通吸引装置910进一步包括至少一疏通元件9123，所述疏通元件9123被安装于所述可视化组件912并能够在所述控制元件9121的控制下运动，所述疏通元件9123能够随着所述可视化组件912一起进入患者的胃部并对胃部内的大颗粒内容物进行粉碎疏通。
详细而言，所述控制元件9121进一步包括至少一旋转模块91213，所述旋转模块91213与所述疏通元件9123可控制地连接，从而使所述控制元件9121能够通孔912310所述旋转模块91213控制所述疏通元件9123进行旋转。
所述疏通元件9123被设置于所述中空管件912211的内部并靠近所述进入端9122111，所述疏通管件被可控制地连接于所述控制元件9121，以使所述疏通管件能够在所述控制元件9121的控制下进行旋转，从而对进入所述中空管件912211的大直径胃部内容物进行粉碎疏通，进而避免所述中空管件912211被堵塞。
如图13和图14所示，所述疏通元件9123包括一疏通头91231，所述疏通头91231被设置为锥体结构并朝向所述中空管件912211的所述进入端9122111的出口从而对进入所述中空管件912211的胃部内容物进行粉碎，且所述疏通头91231的外周均匀设置有多个齿状结构912311，从而提高对胃部内容物的粉碎效果。
进一步地，所述疏通元件9123内部设置有多个通孔912310，多个所述通孔912310被均匀设置于所述疏通元件9123的内部并贯穿所述疏通元件9123，因此当所述疏通元件9123通过其疏通头91231和位于其外周的多个齿状结构912311将胃部内容物粉碎之后，被粉碎的胃部内容物既可以通过实施疏通元件9123与所述中空管件912211之间的间隙被吸收指患者体外，也可以通过所述疏通元件9123内部的多个通孔912310被吸引至患者体外，从而进一步提高本发明所述的经鼻疏通吸引装置910的吸引效果和吸引效率。
优选地，所述疏通元件9123上设置有一反馈元件91232，所述反馈元件91232被连接于所述疏通头91231并能够对所述疏通头91231的周边情况进行反馈，从而使操作人员能够通过所述反馈元件91232及时观察到所述疏通头91231附近的情况，进而判断是否开启所述疏通元件9123进行疏通。
此外，本领域技术人员也可以通过观察所述中空管件912211的所述控制端9122112排出的胃部内容物确定是否需要启动所述疏通元件9123对胃部内容物进行疏通。换言之，若有较大直径的胃部内容物进入所述中空管件912211并堵塞所述中空管件912211，那么所述中空管件912211的所述控制端9122112排出的胃部内容物的量必然会减少甚 至是没有，因此操作人员也可以通过观察通过所述中空管件912211排出的胃部内容物的量来决定是否要启动所述疏通元件9123。
在本发明的第一实施例中，所述疏通元件9123由柔性材料制成，优选为软胶材料制成，从而避免在疏通粉碎过程中对中空管道造成破坏，进而影响本发明所述的经鼻疏通吸引装置910的正常工作。
接下来，如图15所示，对本发明所述的经鼻疏通吸引装置910的第一实施例的工作过程进行进一步的简单说明。
工作时，首先通过所述导入元件911将所述可视化组件912导入患者的鼻腔，同时，在所述可视化组件912中的所述可视元件9122提供的可视前提下，通过所述导入元件911将所述可视化组件912导入患者的食道，此时将所述导入元件911抽离于患者体外。
此时，在所述可视元件9122提供的可视前提下，通过所述可视化组件912中的控制元件9121控制所述中空管件912211带着所述可视元件9122以及所述疏通元件9123一起进入患者胃部；在所述可视元件9122提供的可视提前下，所述可视组件到达患者胃部以后，所述控制元件9121控制所述中空管件912211对患者的胃部内容物进行吸引，在吸引过程中，在所述可视元件9122的作用下，若操作人员看到直径较大的胃部内容物进入所述中空管件912211，则通过控制所述控制元件9121启动所述疏通元件9123进行旋转，所述疏通元件9123中的所述疏通头91231和设置于所述疏通头91231外周的所述齿状结构对所述中空管件912211中的较大直径的胃部内容物进行粉碎疏通，从而避免引起所述中空管件912211的堵塞；直至患者胃部内容物被所述中空管件912211完全吸出。
如图16所示，为本发明所述的经鼻疏通吸引装置910的第一实施例的一变形实施方式的结构示意图。作为本发明的第一实施例的一种改进，与上述第一实施例不同的是，所述疏通元件9123A被设置为能够在所述控制元件9121的控制下伸出所述中空管件912211的外部并靠近所述进入端9122111，从而对无法进入所述中空管件912211的胃部内容物进行粉碎疏通。
也就是说，当所述中空管件912211在所述控制元件9121的作用下开始工作时，胃部内容物在所述中空管件912211的吸力作用下依次进入所述中空管件912211，但对于胃部内容物中直径大于所述中空管件912211的所述通道9122110的直径的部分，则无法进入所述中空管件912211的所述通道9122110。但是，由于胃部内容物在吸力作用下会纷纷向所述中空管件912211的所述通道9122110方向运动，因此将所述疏通元件9123A设置于所述中空管件912211的外部能够使大直径的胃部内容物必然碰到所述疏通元件9123A，并且在所述疏通元件9123A作用下实现粉碎，之后再进入所述中空管件912211的所述通道9122110，从而实现对胃部内容物的吸收疏通。
此外，在该变形实施方式中，由于所述疏通元件9123A被设置于所述中空管件912211的外部，换言之，所述疏通元件9123A被暴露在胃部环境中，因此为了避免所述中空管件912211在粉碎胃部内容物的同时伤害到胃部结构，所述疏通元件9123A的所述疏通头91231的圆锥角度被设置为较大以降低所述疏通头91231的尖锐度，且所述疏通头91231及所述疏通头91231外周的所述齿状结构912311均为软胶材料制成。
除此以外，本领域技术人员可以根据实际情况对所述疏通头91231的圆锥角度和所述疏通元件9123A的材料进行调整，只要在本发明上述揭露的基础上，采用了与本发明相同或近似的技术方案，解决了与本发明相同或近似的技术问题，并且达到了与本发明相同或近似的技术效果，都属于本发明的保护范围之内，本发明的具体实施方式并不以此为限。
如图17所示，为本发明所述的经鼻疏通吸引装置910的第二实施例的结构示意图。与上述第一实施例不同的是，在该第二实施例中，所述经鼻疏通吸引装置910进一步包括一胃管913，且所述可视元件9122被设置为一镜头91223且所述镜头91223并不包括通道。
详细而言，所述胃管913包括一吸取端9131和一操控端9132，其中所述可视元件9122被安装于所述胃管913的所述吸取端9131并能够随着所述吸取端9131而进入患者胃部，所述控制元件9121被连接于所述胃管913的所述操控端9132并能够控制所述胃管913进行运动。
所述疏通元件9123被设置于胃管913内部并靠近所述吸取端9131，从而跟随所述胃管913进入患者内部并对进入胃管913的大直径的胃部内容物进行粉碎疏通。
