Description

多功能冲吸导管
技术领域
本发明涉及一种医疗器械, 尤其是一种手术过程中使用的对创面进行冲 洗和吸引的手术吸引器, 具体地说是一种多功能冲吸导管。
背景技术
众所周知, 在进行外科手术时都要求保持手术视野的清晰, 使外科医生 得以对手术部位进行精确的操作, 故在手术中需要对不断渗出的血及切除的 组织及组织体液进行负压吸除并利用生理盐水不断冲洗出血部位以确保术野 清晰, 为此, 在手术中进行负压吸引时不仅要使用具有负压吸引功能的吸引 头, 还要使吸引头在吸引的同时能进行生理盐水的冲洗, 同时在手术无影灯 照明死角或光照不足的情况下需要另外的辅助装置进行照明, 而当手术部位 渗血等组织体液严重时还要使用冲洗头不断地进行术中冲洗及同步负压吸 除, 在三者并举的情况下大大增加了外科医生的负担, 对医生手术中的工作 效率和准确性造成较大影响。 为此, 人们发明了将负压吸引和生理盐水冲洗 进行集成的多功能手术吸引器, 如申请人在先申请的中国专利
ZL 011100538415 就公开了种防堵型多功能手术吸引器则较好地解决了上述 问题, 但申请人在使用过程中发现这种手术冲洗吸引器存在结构复杂, 操作 不便的问题,尤其是负压和冲洗量控制开关存在结构复杂,所需操作力量大, 负压值和冲洗量调节不便, 操作人员必须用很大的力量压住相应的开关才能 实现冲吸, 操作人员很容易疲劳。 另外, 现有的所有的吸引器的头部均为垂 直平面, 头部端面与吸引头管线垂直, 而在实际操作中一量遇到较大的血块 时, 受负压吸引头管径的影响无法吸出, 此时就必须采用人工清除, 必须更 换工具才能将血块清除找到出血点, 而现有的吸引器因端面垂直无法作为替 换工具直接使用, 造成了手术不便和手术时间的延长。 再者, 该专利采用导 光材料作为照明源也存在照明度不够的问题。 此外, 在具体使用过程中对出 血部位进行处理时, 由于端部结构的缺陷, 冲洗和吸引均需对准出血部位, 由于高强度负压的存在在进行负压吸引时, 由于负压的作用会加重组织出血 部位的血管损伤, 加大出血部位的出血量, 反而易导致冲洗效果差, 视野不 清和增加出血量, 增加手术风险, 对此目前尚无好的解决方法, 影响了该类 手术器械的推广和应用。
发明内容

具体实舫式
下面结合附图和实施例对本发明作进一步的说明。
实施例 1
如图 1- 3所示。
一种多功能冲吸导管, 它由把手 1和管部 2 (可为直管或弯管) 整体相 连而成, 可采用透明材料 (或不透明材料) 注塑形成扣合的壳体结构, 采用 透明材料制造时有利于使用过程中观察内部管路的通堵状态。 把手 1和管部 2 的连接部分采用两段方向相反的平滑过渡的圆弧段相连, 以进一步提高术 野和操作的便利, 其中靠近管部 2的一段圆弧段的开口向上。 为了便于利用 端面对手术部位进行拉刮清理, 方便出血部位的观察, 具体实施时管部 2的 端面与管部轴线的夹角 α应设计成小于 90度, 其中以 60度左右为最佳, 如 图 1、 2。所述的管部 2不与把手 1相连的一端端部设有冲吸通道 3和照明通 道 4,在把手 1的尾部设有负压接口 5和冲洗接口 6,所述的冲吸通道 3中安 装有冲洗头和负压吸引头, 冲洗头和负压吸引头可通过凝固胶定位在冲吸通 道 3中, 所述的负压吸引头通过穿过管部和把手内腔的负压导管 7与负压接 口 5相连通, 所述的冲洗头通过穿过管部和把手内腔的冲洗导管 8与冲洗接 口 6相连通; 在把手 1上安装有控制负压导管 7负压值的滚轮式负压量控制 开关 11 (可直接采用输液中使用的调节输液量的滚轮式调节器加以实现, 将 负压导管作为输液管穿过调节器并与滚轮相接触, 调节滚轮的位置即可调节 负压的大小或通断)以及控制冲洗导管 8冲洗量的滚轮式冲洗量控制开关 12 (可直接采用输液中使用的调节输液量的滚轮式调节器加以实现, 将冲洗导 管作为输液管穿过调节器并与滚轮相接触, 调节滚轮的位置即可调节冲洗量 的大小或通断); 所述的照明通道 4中安装有 LED照明灯 9, 它通过导线 10 与安装有把手 1中的电池 13电气连接, 在把手 1上安装有控制 LED照明灯 9通断的按钮式开关。
具体实施时, 冲吸通道 3中的结构可根据需要自行设计, 可将设计成相 对密封的结构, 可将冲洗管直接从密封腔中伸出, 同时将负压吸引管与密封 腔进行连通,也可直接将负压吸引管的一端与冲洗管的一端通过密封胶固定。
此外, 具体实施时, 负压管和吸引管可全部采用软管或软管加硬管的结 构, 但靠近滚轮式负压量控制开关 11和滚轮式冲洗量控制开关 12的部分必 须采用软管以便于通过调节滚轮的位置来调节负压值及冲洗量。 滚轮式负压 量控制开关 11和滚轮式冲洗量控制开关 12可并排安装在把手 1上, 调节滚 轮凸出把手 1的上表面, 如图 3所示。 使用时, 操作者只需推动滚轮转动即 可调节对应的负压值或冲洗量, 使用十分方便。
实施例 2
如图 4-5所示。
一种从底面吸取、 冲洗与吸引不在同一端面的多功能手术冲吸导管, 它 由把手 1和管部 2整体相连而成, 可采用透明材料 (或不透明材料) 注塑形 成扣合的壳体结构, 采用透明材料制造时有利于使用过程中观察内部管路的 通堵状态。 把手 1和管部 2的连接部分采用两段方向相反的平滑过渡的圆弧 段相连, 以进一步提高术野和操作的便利, 其中靠近管部 2的一段圆弧段的 开口向上。 为了便于手术中进行观察, 不使冲洗管端头遮挡冲洗的视野, 方 便出血部位的判断, 具体实施时管部 2的端面应设计成一个或几个斜面组成 的整体成斜面结构的倾斜状, 斜面与管部轴线的夹角 α应设计成小于 70度, 其中以 30度左右为最佳, 如图 4、 5, 具体实施时为了管路布局方便和制造 便利, 可将斜面设计成由两个角度分别为 60和 30度的斜面组成的结构, 如 图 5所示, 管部 2的端部内部可通过分隔板 1Γ将端部管腔分隔成吸引腔 12 '和冲洗腔 13', 冲洗腔 13'中还可安装照明装置, 在把手 1的尾部设有负压 接口 6和冲洗接口 5, 所述的管部 2设有与负压接口 6和冲洗接口 5相连通 的通道, 所述的通道 (可为连接管道或直接在管部中注塑形成的通道) 分别 与管部 2端部对应的负压吸取孔 4'及冲洗出水孔 3'相连通,所述的冲洗出水 孔 3'位于管部 2端部的斜面 7'的上部, 所述的负压吸取孔 4'主要位于与管 部 2端部的斜面 7'相邻的底面 8'上, 即负压吸取孔 4'的轴心线与冲洗出水 也 3'的轴心线空间相交 (空间垂直或相交), 而传统的负压吸取孔 4'的轴心 线与冲洗出水也 3'的轴心线是空间平行的。在把手 1上安装有控制吸引通道 负压值的滚轮式负压量控制开关 (与实施例一相同, 可直接采用输液中使用 的调节输液量的滚轮式调节器加以实现, 将负压导管作为输液管穿过调节器 并与滚轮相接触, 调节滚轮的位置即可调节负压的大小或通断) 以及控制冲 洗通道冲洗量的滚轮式冲洗量控制开关 (与实施例一相同, 也可直接采用输 液中使用的调节输液量的滚轮式调节器加以实现, 将冲洗导管作为输液管穿 过调节器并与滚轮相接触, 调节滚轮的位置即可调节冲洗量的大小或通断); LED照明灯可安装在管部 2端部的冲洗出水口的一侧并通过导线与安装在把 手 1中的电池电气连接,在把手 1上安装有控制 LED照明灯通断的按钮式开 关。
具体实施时, 除了管部 2端部底面 8'上设置主要的负压吸取孔 4'外,还 可在斜面 7'上也设置负压补充吸取孔 9', 为了防止该负压补充吸取孔 9'吸 力过大对出血部位产生影响, 可在负压补充吸取孔 9加装挡板 14, 如图 3, 此外还可在所述的主负压吸取孔 4'的两侧或单侧孔壁上设有若干个侧向负 压吸取孔 10', 所述的负压吸取孔 4'、 负压补充吸取孔 9'和侧向负压吸取孔 10'应相互连通,且负压补充吸取孔 9'、侧向负压吸取孔 10'的最高位置不超 过沿管部 2的中心轴线所作的水平面的高度, 补充吸取孔的孔径应该明显小 于吸取孔 4'的孔径。
此外, 具体实施时, 负压管和吸引管可全部采用软管或软管加硬管的结 构, 但靠近滚轮式负压量控制开关和滚轮式冲洗量控制开关的部分必须采用 软管以便于通过调节滚轮的位置来调节负压值及冲洗量。 滚轮式负压量控制 开关和滚轮式冲洗量控制开关可并排安装在把手上, 调节滚轮凸出把手 1的 上表面, 如图 4所示。 使用时, 操作者只需推动滚轮转动即可调节对应的负 压值或冲洗量, 使用十分方便。
使用时, 将本发明的冲洗出水口对准出血部位进行冲洗, 冲洗产生的液 体向低处流动时正好被管部端部下表面上的负压吸引孔吸入, 由于负压吸引 孔不直接与出血部位相对,因此从根本上解决了负压吸引力对出血量的影响, 此外, 管部的大斜面一方面加大了冲点与吸点之间的距离, 另一端开阔了手 术视野, 使医生使用更为得心应手。
本发明未涉及部分均与现有技术相同或可采用现有技术加以实现。
