本申请要求了2021年11月16日提交的中国发明专利申请CN202111358294.1的权益，该申请的内容通过引用被合并于本文。
技术领域
本发明涉及医疗器械领域，具体地，涉及一种冲洗吸引管。此外，还涉及一种手术装置。
背景技术
随着医疗技术的快速发展，人们不仅仅要求手术能够治愈疾病，同时还希望减少手术本身对患者造成的损伤，实现微无创化手术，如腹腔镜手术，需要在患者腹壁甚至背部通过穿刺器来建立手术通道，以减少对患者造成的损伤。腹腔镜手术是器械高度依赖的术式，其中能量器械如单极、双极等能量器械的应用，在手术切割、止血等操作中不可或缺。
目前大部分能量器械均是采用热能或高速低频震荡的机械能来导致蛋白变性，在这个过程中，会产生大量烟雾。烟雾产生带来的问题：1.影响手术安全性：大量烟雾妨碍手术视野，使操作区域模糊不清，影响手术操作安全；2.影响手术的连续性，增加手术时间成本，有时需要暂停手术，待烟雾消散、手术视野清晰后，才能继续手术操作；3.对接受手术患者、参与手术的医生和护士的健康产生潜在危害：手术烟雾含有多种有害化学成分(有机或无机化合物)，甚至是致癌物质，有学者已经在手术烟雾里发现至少4种明确的致癌物质：1,3-丁二烯，氰化氢，乙炔，有机苯，烟雾可被患者腹盆腔内壁及脏器表面浆膜、腹膜吸收，有研究发现在腹腔镜手术病人的尿液中，检测到了苯和甲苯明显升高，不利于手术后康复，甚至对患者健康产生潜在危害；4.对手术医生健康产生危害：手术烟雾除产生上述对人体有害或致癌物质外，还可产生强烈异味和传染性生物颗粒，有研究报道电外科处理的1g人体组织所产生的烟雾的危害性相当于人体吸入6支未过滤的香烟。而一台手术产生的烟雾的有害物质量，相当于27到30支香烟产生的有害烟雾。77％的手术烟雾颗粒是小于1.1um的，平均直径仅0.07um，也包 含一些超细微粒，平均直径10nm到1um，尽管外科口罩防护严密，但小于5um的微粒，可直接穿过口罩吸入进肺。另外，有害物质(苯乙烯，致畸剂等)可以通过眼睛等部位直接进入身体，对人体造成损害。而且，在腹腔镜技术中，腹腔镜的镜头通常会被腹膜或其他体液、血液、气雾脂肪、组织颗粒、烟、碎片或冷凝物污染，会影响医师的视野(通过外部的监视器)。
因此，如何有效排出或消除手术中能量器械使用产生的烟雾、快速清洁内窥镜的镜头并保证手术的安全性和连续性是一直以来外科相关研究的领域的亟待解决的技术问题。

具体实施方式
以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“设置”或“连接”应做广义理解，例如，术语“连接”可以是固定连接，也可以是可拆卸连接，或者是一体连接；可以是直接连接，也可以是通过中间媒介间接连接，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
此外，术语“第一”、“第二”、“第三”仅用于描述的目的，而不能理解为指示或暗示相对重要性或隐含指明所指示的技术特征的数量，因此，限定有“第一”、“第二”、“第三”的特征可以明示或隐含地包括一个或更多个所述特征。
在本发明中，在未作相反说明的情况下，使用的方位词如“内、外”是以相应部件的内和外定义的，另外，术语“近侧”和“远侧”是指临床医生在操纵手术器械时距离手术器械上的各部分结构的远近。“近侧”是指靠近临床医生的部分，“远侧”是指远离临床医生的部分，例如，管接头组件2位于近侧，并且“轴向”是以本发明提供的冲洗吸引管布置方向定义的，具体地在本发明提供的附图中，“轴向”为管体1前后方向。使用的方位词为基于附图所示的方位或位 置关系，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制；对于本发明的方位术语，应当结合实际安装状态进行理解。
如图1至图9所示，本发明基本实施方式的冲洗吸引管，包括管体1和管接头组件2，管接头组件2上设有第一接头21、第二接头22和第三接头23，管体1内形成有排抽通道11、液体输送通道12和气体输送通道13，排抽通道11贯通管体1的两端，管接头组件2套设在管体1的近侧端，管接头组件2与管体1可以为分体结构，也可以为一体结构，且第一接头21与排抽通道11连通，第二接头22与液体输送通道12连通，第三接头23与气体输送通道13连通，管体1的管口结构设有与排抽通道11连通的第一排烟结构14，且管体1上靠近其管口结构的位置设有喷液孔15和喷气孔16，喷液孔15与液体输送通道12连通，喷气孔16与气体输送通道13连通。
在微创手术中，参考图10，微创手术中常用的能量器械7穿过排抽通道11并伸入到腹腔内需要手术的部位。第一排烟结构14设置在管体1的管口结构位置，靠近能量器械7的工作端，即紧邻烟雾产生源头，可以使手术中产生的烟雾在产生的瞬间即被排出体外；能量器械7通常与内窥镜配合使用，在管体1上还设置有喷液孔15和喷气孔16，喷液孔15用于向外喷液，一般地，选择生理盐水，温度一般为37～39℃，当内窥镜的镜头被腹膜或其他体液、血液、气雾脂肪、组织颗粒、烟、碎片或冷凝物污染时，第二接头22与清洗液提供装置连接，通过喷液孔15向内窥镜的镜头喷射生理盐水，清洗内窥镜的镜头；同时，第三接头23与气体提供装置连接，通过喷气孔16向内窥镜的镜头喷气，一般选择二氧化碳气体，将内窥镜的镜头上附着的液体吹干，从而为手术提供清晰视野。但是，在实际使用中，液体输送通道12也可以用于输送气体，即喷液孔15用于喷射气体；相应地，气体输送通道13也可以用于输送气液体，即喷气孔16用于喷射液体；也就是说，液体输送通道12和气体输送通道13两者中，一个能够用于输送气体，另一个用于输送液体，这同样属于本发明的保护范围。而且，排抽通道11除了能够用于排烟，也可以用于将冲洗内窥镜镜头的清洗液、其他用途的清洗液或人体自身液体吸出，排出体外。
其中，液体输送通道12和气体输送通道13可以为沿轴向的直线通道，也 可以为曲线通道，如以螺旋线的形式布置在管体1的内壁上。
具体地，管体1内设有分隔件，分隔件与管体1内壁相连形成排抽通道11、液体输送通道12以及气体输送通道13，分隔件可以为图5所示的结构，使液体输送通道12与气体输送通道13相邻近，在结构上也可以进行一定变形，如分隔件上方的水平直板可以为曲型板，分隔件下方的竖直板可以为曲型板；或者，分隔件也可以将管体1内空间分隔形成为图6所示的结构，使液体输送通道12与气体输送通道13分开布置；或者，管体1内也可以设置其它结构，以将管体1内的空间分隔为排抽通道11、液体输送通道12以及气体输送通道13。为了不影响排抽通道11的排烟效果以及能量器械的工作，液体输送通道12和气体输送通道13的远侧端被管体1的内壁封堵，即管体1的管口结构仅与排抽通道11连通。另外，也可以通过其它方式设计液体输送通道12以及气体输送通道13，例如，管体1的管壁的厚度较大，使液体输送通道12以及气体输送通道13设置在管体1的管壁内。
其中，第一接头21、第二接头22和第三接头23可以采用塔形防松接头，塔形防松接头带有锥形防松台阶结构，使第一接头21通过软管与手术排烟器连接，手术排烟器可以采用负压泵或风扇，提供排烟动力将烟雾排出，使第二接头22通过软管与清洗液提供装置连接，清洗液提供装置可以包括水泵与生理盐水存储容器，使第三接头23通过软管与气体提供装置连接，气体提供装置可以包括气压泵与二氧化碳存储容器等，或者，第一接头21、第二接头22和第三接头23也可以采用其它连接形式，如螺纹结构等。
进一步地，还可以在第一接头21、第二接头22和第三接头23上均安装有控制件，控制第一接头21、第二接头22和第三接头23等的启闭。具体地，参考图11，在第一接头21上设置排抽开关81，用于控制第一接头21的启闭，在第二接头22上设置喷液开关82，用于控制第二接头22的启闭，在第三接头23上设置喷气开关82，用于控制第三接头23的启闭。此外，第一接头21可以为三通阀，一个端口与排抽通道11连通，另一个端口连接手术排烟器，用于排出手术时产生的烟雾，另一个端口连接抽吸装置，用于抽出清洗内窥镜镜头时产生的清洗液、其他用途的清洗液或人体自身液体。
在具体实施例中，第一排烟结构14可以为开口，参考图12，该开口可以 为由管体1管口结构向近侧凹陷形成的凹口，或者，参考图14，该开口可以为其它结构，如圆孔或矩形孔等。此外，参考图13，管体1的管口结构为外锥结构，外锥结构是指如图14所示的外轮廓为由远侧向近侧逐渐增大的圆锥面的结构，相对于管口结构，能够减小对手术器械头部的遮挡，方便内窥镜观察，而且插入穿刺器时更加顺畅。其中，外锥结构的内轮廓自远侧向近侧横截面周长逐渐增大的圆锥面18，从而方便手术器械顺畅插入；外锥结构远侧端口设有倒角19，方便手术器械的顺畅退出。
此外，还可以在管体1的侧壁上设置第二排烟结构17，第二排烟结构17与排抽通道11连通，能够增加排烟的面积。具体地，第二排烟结构17为孔结构，如圆孔、矩形孔等，喷液孔15的孔径小于第二排烟结构17的孔径，喷气孔16的孔径也小于第二排烟结构17的孔径，喷液孔15的孔径与喷气孔16的孔径可以相同，也可以不同。
进一步地，第二排烟结构17靠近管体1的管口结构设置，如沿管体1外周面周向布置，或者沿管体1外周面轴向布置，喷液孔15与喷气孔16的布置位置也靠近管体1的管口结构，可以矩阵式排布。
为了方便操作，可以在喷液孔15的布置位置附近设置液体喷射标记以及在喷气孔16的布置位置附近设置气体喷射标记，指示喷液孔15与喷气孔16位置，在微创手术中，便于手术医师快速找到喷液孔15与喷气孔16，清洁内窥镜的镜头。还可以在管体1的近侧端，即靠近管接头组件2的区域的外表面设置刻度标记，便于提示手术医师冲洗吸引管的插入深度。
为了更好地冲洗内窥镜的镜头，可以将喷液孔15设计为倾斜的通孔，即喷液孔15的轴线与管体1的轴线之间具有锐角，例如，将喷液孔15设计为向近侧倾斜，使喷液孔15由远侧向近侧倾斜喷射生理盐水，或者，也可以将喷液孔15设计为向其它方向倾斜。同理地，喷气孔16也可以设计为倾斜的通孔，便于由远侧向近侧倾斜喷射二氧化碳气体。由于喷液孔15和/或喷气孔16向近侧倾斜设计，在实际操作中，能够对内窥镜的镜头进行更好地清洗。通孔可为单个，也可为多个，例如梅花形排列。参见图15，这些通孔的角度可以是不同角度的，使得清洗区域的覆盖范围更大，其中，双点划线表示通孔倾斜角度的方向。当然，喷液孔15和喷气孔16也可以不倾斜设计。
进一步地，参见图16，管体1侧壁上设有导流槽9，导流槽9布置在所述喷液孔15和所述喷气孔16之间，该导流槽9也可以是导流脊，导流脊是指突起结构。喷液后，在喷气孔16上可能出现喷液后的残留液体，使得喷气时该残留液体会被气体喷射到镜头表面。导流槽可以引导液体流走，远离喷气孔，导流脊可阻挡液体流到喷气孔上。
在一些具体实施例中，管接头组件2的端部安装有端盖3，端盖3与管体1分别位于管接头组件2的两端；管接头组件2内形成有器械进出通道，与管体1内的排抽通道11连通，端盖3中心设置通孔，手术器械能够通过端盖3中心的通孔依次穿过管接头组件2内的器械进出通道以及管体1内的排抽通道11伸出管体1管口结构，例如能量器械7，进行相应的手术操作。
进一步地，参考图1，端盖3与管接头组件2之间设有第一密封垫4和第二密封垫6，第一密封垫4和第二密封垫6可以为分体结构，实现端盖3与管接头组件2之间的密封。或者，在优选情况下，第一密封垫4和第二密封垫6可以为一体成型结构。当然，第一密封垫4和第二密封垫6在管接头组件2与端盖3之间的安装顺序可以如图1所示，也可以为设计为管接头组件2、第二密封垫6、第一密封垫4以及端盖3的安装顺序。而且，还可以设置垫片5，例如设置在第一密封垫4和第二密封垫6之间，垫片5可以为硬质材料，便于固定支撑第一密封垫4和第二密封垫6。
其中，参考图9，第一密封垫4包括筒体41和密封缘42，密封缘42可以为图9所示的环形结构，能够与管接头组件2的内壁密封，或者，也可以为由筒体41延伸出的延展边，或者，其它能够实现与管接头组件2的内壁密封的结构；密封缘42沿沿筒体41外周面布置；筒体41端口设置有多瓣密封结构43，多瓣密封结构43可以为图9所示的两瓣结构，或者其它多瓣结构，一般可以由医用硅胶、橡胶或其它弹性材料制备，在能量器械、穿刺针等医疗器械穿过后，多瓣密封结构43的瓣膜结构能够相互紧密贴合，实现密封作用。参考图7和图8，第二密封垫6可以为阶梯轴结构，其远侧端向外凸起，其近侧端为向内凹陷的阶梯孔，在其筒体的外周面上沿轴向布置延展边，能够与管接头组件2内壁密封，并且轴向设置有贯通其前后的通孔，便于能量器械7等医疗器械穿过，并且能够与能量器械等医疗器械的外表面紧密贴合，实现密封作用，或者，第二密封垫6 可以为其它能够实现密封的结构。也就是说，在未插入能量器械7、穿刺针等手术器械时，第一密封垫4的多瓣结构相互贴合，实现密封作用。当插入能量器械7等手术器械后，第二密封垫6起密封作用。
为了更好地理解本发明的技术方案，以下结合相对全面的优选技术特征对优选实施例进行说明。
如图1至图9所示，本发明提供一种冲洗吸引管，包括管体1、管接头组件2和端盖3；管体1内设置有T型分隔板，T型分隔板与管体1的内壁相连将管体1内的空间分割为排抽通道11、液体输送通道12和气体输送通道13，液体输送通道12的远侧端和气体输送通道13的远侧端均与内壁相连形成封闭结构，排抽通道11与管体1的管口结构连通，且管体1的管口结构设有第一排烟结构14，管体1上靠近其管口结构的位置设有喷液孔15和喷气孔16，喷液孔15与液体输送通道12连通，喷气孔16与气体输送通道13连通，喷液孔15向近侧倾斜设置；管体1上还设置有第二排烟结构17，第二排烟结构17与排抽通道11连通。管接头组件2的一端密封套设在管体1上，管接头组件2上设置有第一接头21、第二接头22和第三接头23，第一接头21与排抽通道11连通，第二接头22与液体输送通道12连通，第三接头23与气体输送通道13连通；管接头组件2的另一端安装有端盖3，且管接头组件2与端盖3之间安装有第一密封垫4、垫片5和第二密封垫6。
参考图10，在微创手术中使用本发明的手术装置时，将第一接头21与手术排烟器连接，将第二接头22与清洗液提供装置连接，将第三接头23与气体提供装置连接；能量器械7依次穿过端盖3、管接头组件2以及管体1内的排抽通道11伸出到管体1的外部，对准手术位置进行切割、止血等操作，随着操作进行会产生烟雾，由于第一排烟结构14位于管体1的管口结构位置，紧邻烟雾产生源头，可以使产生的烟雾在产生瞬间及时排出。其中，能量器械7与能量发生器连接，通常在能量发生器的电源输入线路上设置传感器，如霍尔传感器，用于监测提供给能量器械7的电流、电压或者功率，将监测到能量器械7的启动信号传输给控制器，根据启动信号，控制器控制手术排烟器中的负压泵或风扇同步启动，从而实现排烟与能量器械7自动同步启动，自动及时排烟至患者体外做过滤净化等处理，保障手术无间断完成，保障手术室的环境安全；能量器械7可自如 进出器械通道，实现不同手术器械的转换，器械更换也仍可进行排烟。而且，当与内窥镜配合使用时，喷液孔15能够向内窥镜的镜头喷射生理盐水，快速对内窥镜镜头进行清洗，喷气孔16能够向内窥镜的镜头喷射二氧化碳气体，将内窥镜镜头上附着的液体吹干，提供清晰的视野，无须取出器械，保障手术无障碍实施，节约手术时间。
以上结合附图详细描述了本发明的优选实施方式，但是，本发明并不限于上述实施方式中的具体细节，在本发明的技术构思范围内，可以对本发明的技术方案进行多种简单变型，这些简单变型均属于本发明的保护范围。
另外需要说明的是，在上述具体实施方式中所描述的各个具体技术特征，在不矛盾的情况下，可以通过任何合适的方式进行组合。为了避免不必要的重复，本发明对各种可能的组合方式不再另行说明。
此外，本发明的各种不同的实施方式之间也可以进行任意组合，只要其不违背本发明的思想，其同样应当视为本发明所公开的内容。
