Description

左心耳结扎器 技术领域
本发明涉及医疗器械技术领域，具体为左心耳结扎器。
背景技术
左心耳是一个狭长的管状盲腔，形状不规则，存在多段曲折，大小与拇指相当，开口大小为10mm～40mm。左心耳内存在丰富的梳状肌及肌小梁，故其内血流易产生涡流及流速减慢，是血栓形成的好发部位。
心房颤动(atrialfibrillation，AF)患者中风风险明显增加。研究提示，60％的风湿性心脏病患者合并心房颤动(下文简称房颤)的心源性血栓来自左心耳(LAA)，91％非瓣膜性房颤(AF)造成的卒中是由左心耳内血栓导致。因此去除LAA将有助于减少左心房血栓和中风事件。
心脏外科手术同时切除或封闭左心耳简单易行，因此许多医生主张对于此类患者需心脏手术治疗的同时切除或封闭左心耳，但是对于仅仅是切除或封闭左心耳来说外科手术创伤面很大，不宜施行外科手术，因此结扎成为首选的治疗方式，但是传统的结扎器不便实现自动打结，需要施加外部器具进行操控，从而导致手术时间较长，影响手术质量和效率，为此提供一种左心耳结扎器。
发明内容
为了解决现有技术传统的结扎器不便实现自动打结，需要施加外部器具进行操控，从而导致手术时间较长，影响手术质量和效率的问题，本发明提供一种左心耳结扎器，采用如下的技术方案：
一种左心耳结扎器，包括结扎线和操作手柄，所述操作手柄的一端固定连接有支杆，所述支杆的内壁固定连接有供给管和锁紧管，所述供给管的内侧壁开设有第一滑槽，所述第一滑槽的内侧壁滑动连接有第一滑块，第一滑块的中部固定连接有供给推杆，所述供给推杆的一端固定连接有第一挂钩，所述第一滑块的一侧固定连接有复位弹簧，所述锁紧管的内侧壁开设有第二滑槽，所述第二滑槽内滑动连接有第二滑块，所述第二滑块的一端固定连接有第二挂钩，所述第二挂钩的另一侧固定连接有锁紧推杆，所述锁紧管内壁与第二滑槽相邻开设有滑动空腔，所述滑动空腔内插接有支撑组件，所述结扎线的一端在结扎线 中部缠绕形成上吊结，使结扎线的前端围绕形成一个活套，所述活套设置于支撑组件外壁的一端。
通过上述技术方案，通过供给管和锁紧管的设置，供给管和锁紧管均为可拆卸结构，从而方便操作人员对供给管和锁紧管进行拆卸，以更换不同的结扎线，从而实现重复使用该结扎器。
可选的，所述供给管包括直管部和导向部，所述导向部的一端与直管部螺纹连接，从而方便操作人员拆分供给管，对结扎线进行固定，所述锁紧管包括固定部和拆卸部，所述拆卸部的一端与固定部螺纹连接，从而方便拆卸锁紧管对结扎线的另一端进行固定。
可选的，所述结扎线贯穿导向部的一端系附在第一挂钩的表面，所述结扎线贯穿拆卸部的一端系附在第二挂钩的表面，从而方便在每次使用时更换不同的结扎线。
可选的，所述支撑组件包括插接在活动空腔内的支撑杆，所述支撑杆的一端固定连接有套管部，所述套管部的中部开设有供结扎线穿设的导孔，所述套管部的外壁开设有与结扎线相适配的暂存槽，暂存槽能够提高摩擦力，避免结扎线自动脱落锁死。
可选的，所述操作手柄包括固定把手，所述固定把手的内侧壁通过转轴可转动连接有握把，所述握把的顶部设置有与推杆相适配的推板，所述推杆的一端抵紧所述推板的侧壁，从而方便通过推板推动推杆，实现对结扎线产生的套圈大小进行调节。
可选的，所述支撑杆的一端和锁紧推杆的一端均固定连接有推钮，所述固定把手的上表面开设有与推钮相适配的水平滑槽，所述推钮滑动连接在水平滑槽的内壁，从而方便通过推钮操控结扎线锁死以及控制导管部与结扎线脱离。
可选的，所述固定把手内壁的顶部固定连接有缓冲弹簧，所述缓冲弹簧的一端与其中一个推钮固定连接，从而在锁死后，缓冲弹簧推动推钮进而将上吊结排出，方便操作人员对结扎线进行裁剪。
一种左心耳结扎器的使用方法，包括以下具体步骤：
STEP1，结扎线预设于套管部上构成上吊结；
STEP2，操作人员按压握把，结扎线伸出围合成的结扎圈，扩大至能够通过左心耳外轮廓，结扎圈的尺寸设定为50-70mm；
STEP3，操作人员在手术器械的帮助下降结扎圈通过左心耳外轮廓直至结扎位置；
STEP4，确定结扎圈套在结扎位时，操作人员向后滑动支撑杆一端的推钮，从而带动套管部回收，使得结扎线脱离套管部，同时向后滑动锁紧推杆一端的推钮带动上吊结锁死，实现自动打结；
STEP5，切断上吊结尾部的结扎线，取出左心耳结扎器即可。
通过上述技术方案，操作人员按压把手即压缩握把，通过握把推动供给推杆进而推动第一滑块压缩复位弹簧，使得供给推杆延伸，进而带动结扎线的活动端伸出，结扎线伸出时在套管部内滑动，通过套管部对上吊结进行支撑，有效避免上吊结自动锁死，且套管部的表面开设有暂存槽，从而提高套管部1面的摩擦力，提高储存结扎线的能力，结扎线围合成的结扎圈扩大后，能够方便操作人员快速套装左心耳，且通过复位弹簧自动对结扎线进行收缩，需要对上吊结进行锁死时，向后滑动支撑杆一端的推钮，从而带动套管部回收，使得结扎线脱离套管部，同时向后滑动锁紧推杆一端的推钮带动上吊结锁死，从而实现自动打结，结扎线预设于套管部上构成上吊结，从而避免在手术过程中打结，手术时只需要锁死上吊结即可完成打结，从而降低手术时间，提高手术效率。
可选的，还有更换结扎线的具体操作方法：
操作人员将导向部与直管部螺纹拆卸，同时将拆卸部与固定部螺纹拆卸，将结扎线与第一挂钩缠绕打结固定，将结扎线的中部缠绕形成上吊结并挂在套管部上，结扎线的另一端穿入上吊结后与第二挂钩打结固定。
通过上述技术方案，可以便捷的更换结扎线，实现左心耳结扎器的多次使用，避免器械的浪费。
本发明提供了左心耳结扎器，具备以下有益效果：
1、左心耳结扎器，通过供给管和锁紧管的设置，供给管和锁紧管均为可拆卸结构，从而方便操作人员对供给管和锁紧管进行拆卸，以更换不同的结扎线，从而重复使用该结扎器。
2、左心耳结扎器，通过操作手柄、第一滑块、第一滑槽、供给推杆和复位弹簧的设置，第一滑块通过复位弹簧与供给管构成弹性配合，从而方便通过操作手柄压缩复位弹簧为结扎线进行供给，扩大结扎线围合成的结扎圈，从而方便将结扎线自动套在左心耳上，且通过复位弹簧自动对结扎线进行收缩为打扣提供便利。
3、左心耳结扎器，锁紧推杆、结扎线、上吊结和支撑组件的设置，结扎线预设于套管部上构成上吊结，从而避免在手术过程中打结，手术时只需要锁死上吊结即可完成打结，套管部作为支撑供结扎线另一端穿设从而避免自动锁死，套管部与上吊结脱离后即可拉动上吊结进行自动锁死，从而降低手术时间，提高手术效率。

请参阅图1至图5，本发明提供一种技术方案：左心耳结扎器，包括结扎线1和操作手柄2，操作手柄2的一端固定连接有支杆，支杆的内壁固定连接有供给管3和锁紧管4，供给管3的内侧壁开设有第一滑槽5，第一滑槽5的内侧壁滑动连接有第一滑块6，第一滑块6的中部固定连接有供给推杆8，供给推杆8的一端固定连接有第一挂钩7，第一滑块6的一侧固定连接有复位弹簧9，锁紧管4的内侧壁开设有第二滑槽，第二滑槽内滑动连接有第二滑块10，第二滑块10的一端固定连接有第二挂钩11，第二挂钩11的另一侧固定连接有锁紧推杆12，锁紧管4内壁与第二滑槽相邻开设有滑动空腔，滑动空腔内插接有支撑组件，结扎线1的一端在结扎线1中部缠绕形成上吊结101，使结扎线1的前端围绕形成一个活套，活套设置于支撑组件外壁的一端。
其中，操作手柄2包括固定把手201，固定把手201的内侧壁通过转轴可转动连接有握把202，握把202的顶部设置有与供给推杆8相适配的推板，供给推杆8的一端抵紧推板的侧壁，从而方便通过推板推动供给推杆8，实现对结扎线1产生的套圈大小进行调节；
此外，支撑杆13的一端和锁紧推杆12的一端均固定连接有推钮16，固定把手201的上表面开设有与推钮16相适配的水平滑槽，推钮16滑动连接在水平滑槽的内壁，从而方便通过推钮操控结扎线锁死以及控制导管部与结扎线脱离，固定把手201内壁的顶部固定连接有缓冲弹簧17，缓冲弹簧17的一端与其中一个推钮16固定连接，从而在锁死后，缓 冲弹簧17推动推钮进而将上吊结101排出，方便操作人员对结扎线进行裁剪；
最后，支撑组件包括插接在活动空腔内的支撑杆13，支撑杆13的一端固定连接有套管部14，套管部14的中部开设有供结扎线1穿设的导孔15，套管部14的外壁开设有与结扎线相适配的暂存槽，暂存槽能够提高摩擦力，避免结扎线1自动脱落锁死；
一种左心耳结扎器的使用方法，其特征在于：包括以下具体步骤：
STEP1，结扎线1预设于套管部上构成上吊结101；
STEP2，操作人员按压握把202，结扎线1伸出围合成的结扎圈，扩大至能够通过左心耳外轮廓，结扎圈的尺寸设定为50-70mm；
STEP3，操作人员在手术器械的帮助下降结扎圈通过左心耳外轮廓直至结扎位置；
STEP4，确定结扎圈套在结扎位时，操作人员向后滑动支撑杆13一端的推钮，从而带动套管部14回收，使得结扎线1脱离套管部14，同时向后滑动锁紧推杆12一端的推钮16带动上吊结101锁死，实现自动打结；
STEP5，切断上吊结101尾部的结扎线1，取出左心耳结扎器即可。
具体的使用时，操作人员按压把手即压缩握把202，通过握把202推动供给推杆8进而推动第一滑块6压缩复位弹簧9，使得供给推杆8延伸，进而带动结扎线1的活动端伸出，结扎线1伸出时在套管部14内滑动，通过套管部14对上吊结101进行支撑，有效避免上吊结101自动锁死，且套管部14的表面开设有暂存槽，从而提高套管部14表面的摩擦力，提高储存结扎线1的能力，结扎线1围合成的结扎圈扩大后，能够方便操作人员快速套装左心耳，且通过复位弹簧9自动对结扎线1进行收缩，需要对上吊结101进行锁死时，向后滑动支撑杆13一端的推钮，从而带动套管部14回收，使得结扎线1脱离套管部14，同时向后滑动锁紧推杆12一端的推钮16带动上吊结101锁死，从而实现自动打结，结扎线1预设于套管部上构成上吊结101，从而避免在手术过程中打结，手术时只需要锁死上吊结101即可完成打结，从而降低手术时间，提高手术效率。
实施例2
请参阅图2、图3、图4和图5，为了实现重复使用降低成本以及便于组装的目的，将供给管和锁紧管设置成可拆分结构，具体为：
供给管3包括直管部301和导向部302，导向部302的一端与直管部301螺纹连接，从而方便操作人员拆分供给管3，对结扎线1进行固定，锁紧管4包括固定部401和拆卸部402，拆卸部402的一端与固定部401螺纹连接，从而方便拆卸锁紧管4对结扎线1的另一端进行固定；
其中，结扎线1贯穿导向部302的一端系附在第一挂钩7的表面，结扎线1贯穿拆卸部402的一端系附在第二挂钩11的表面，从而方便在每次使用时更换不同的结扎线；
具体的，使用时，操作人员在更换结扎线时，将导向部302与直管部301螺纹拆卸，同时将拆卸部402与固定部401螺纹拆卸，操作人员将结扎线1与第一挂钩7缠绕打结固定，将结扎线1的中部缠绕形成上吊结101并挂在套管部14上，结扎线1的另一端穿入上吊结101后与第二挂钩11打结固定。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术操作人员在本发明揭露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内，其中在本说明书的描述中，术语“连接”、“安装”、“固定”、“设置”等均做广义理解，例如，“连接”可以是固定连接或在不影响部件关系与技术效果的基础上通过中间组件间接进行，也可以是一体连接或部分连接，如同此例的情形对于本领域普通技术操作人员而言，可根据具体情况理解上述术语在本发明或发明中的具体含义。
