Description

一种止血夹
本申请要求在2020年6月12日提交中国专利局、申请号为202021092125.9、发明名称为“一种止血夹”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及医疗器械技术领域，特别涉及一种止血夹。
背景技术
近年来，由于内窥镜治疗技术具有创伤面积小、疼痛轻、恢复快等优点，正受到越来越多急性消化道出血患者和医生的青睐。通过将内镜置入人体内部，然后配合一系列的止血夹，可以有效的对出血部位进行标记、止血、包扎，最终达到愈合的效果，这大大避免了通过外科手术治疗创口而造成的不适感与疼痛感。金属止血夹止血属于物理止血，即通过止血夹夹片之间的闭合力，将创口周围的组织及出血血管夹闭并固定，从而达到止血的效果。
对于一般较小的创口可以用普通的夹子将其结扎，并达到止血的目的。在现有技术中，止血夹包括一个手柄和两个活动夹臂，通过手柄上滑块的运动，带动两个活动夹臂开合，从而实现较小创口的夹闭固定。但是对于较大的创口，由于这种止血夹的两个活动夹臂的开合距离较小，从而无法实现较大创口的夹闭固定，达不到止血的目的。
发明内容
本申请要解决的技术问题为提供一种止血夹，该止血夹能够实现较大创口的夹闭固定，达到止血目的，并且结构简单，成本较低。
为解决上述技术问题，本申请提供一种止血夹，包括位于近侧端的手柄部和位于远侧端的夹臂部，并所述手柄部与所述夹臂部可分离连接；所述手柄部上设有驱动所述夹臂部开合的联动部件；
所述手柄部包括至少两个手柄，所述夹臂部包括固定夹臂和活动夹臂，所述活动夹臂的数量与所述手柄的数量相同；每一个所述手柄均设有所述联动部件，并在所述联动部件的驱动下，一个所述手柄控制一个所述活动夹臂与所述固定夹臂开合；任两个所述手柄之间的夹角不变。
可选的，所述手柄的数量为两个，并呈Y型；所述联动部件的数量为两个；两个 所述活动夹臂分置于所述固定夹臂的两侧。
可选的，两个所述手柄为一体形成的部件。
可选的，两个所述手柄为分体部件；所述手柄部还包括成Y型的三通管，两个所述手柄分别插入所述三通管的两个分叉的管道中。
可选的，所述联动部件为滑块，所述滑块可移动套于所述手柄的圆周外部，以便随着所述滑块移动，带动所述活动夹臂与所述固定夹臂开合。
可选的，所述止血夹包括连接线，所述连接线在近侧端与所述滑块连接，在远侧端与所述活动夹臂连接。
可选的，所述止血夹还包括连杆，所述连接线在远侧端通过连杆与所述活动夹臂连接。
可选的，所述夹臂部包括夹座，所述夹座沿轴向开设有第一滑槽，所述连杆的一端连接有活动销轴，所述活动销轴可移动设于所述第一滑槽中；所述活动夹臂设有与所述活动销轴配合的圆形孔，以便所述活动夹臂相对于所述活动销轴转动。
可选的，所述夹座上设有固定销轴，所述活动夹臂上设有与所述固定销轴配合的呈长条状的第二滑槽，以便所述活动夹臂运动时，基于所述第二滑槽对所述固定销轴的限位，驱动所述活动夹臂相对于所述活动销轴发生转动。
可选的，所述圆形孔开设有缺口；所述夹座内部设有固定台阶，所述活动夹臂设有与所述固定台阶配合的尾部倒钩，以便当所述活动销轴脱离所述圆形孔时，撑开所述缺口，使得所述尾部倒钩卡在所述固定台阶上。
可选的，所述夹臂部还包括固定帽，及连接于所述夹座与所述固定帽之间的过渡帽。
可选的，所述过渡帽的圆周壁上均匀分布有三个连接孔，该三个连接孔配合有三爪卡扣；所述连杆的外部套有圆环，以便连杆移动时下压固定环，所述固定环下压三爪卡扣，使得过渡帽与所述夹座分离。
可选的，任两个所述手柄之间的夹角为0-180度。
可选的，任两个所述手柄之间的夹角为60-120度。
在一种实施例中，本申请所提供的一种止血夹，包括位于近侧端的手柄部和位于 远侧端的夹臂部，并所述手柄部与所述夹臂部可分离连接；所述手柄部上设有驱动所述夹臂部开合的联动部件；所述手柄部包括至少两个手柄，所述夹臂部包括固定夹臂和活动夹臂，所述活动夹臂的数量与所述手柄的数量相同；每一个所述手柄均设有所述联动部件，并在所述联动部件的驱动下，一个所述手柄控制一个所述活动夹臂与所述固定夹臂开合；任两个所述手柄之间的夹角不变。
在上述技术方案中，当对创伤周围的组织及出血血管进行夹闭操作时，由于活动夹臂的数量为多个，并且手柄的数量也为多个，每个手柄可以通过联动部件单独控制相应的活动夹臂与固定夹臂的开合，因而当创伤较大时，该种止血夹也能够适用，达到止血目的。此外，在该种技术方案中，通过增加手柄及相应的活动夹臂的数量，因而也结构简单，制造成本也较低。
此外，由于手柄与手柄之间的夹角不变，比如通过硬质材质或其他装置予以固定，因而手柄与手柄之间的夹角不会发生变化，这种结构在人手进行握持时操作更方便，从而能够更方便驱动滑块，进而驱动夹臂的开合操作，更有利于创伤的夹闭操作。
综上所述，本申请所提供的止血夹能够实现较大创口的夹闭固定，达到止血目的，并且结构简单，成本较低。

此外，还需要说明的是，作为一种举例，如图1所示，手柄部是一个部件集成，可以包括图1中整体的结构全部和一部分，本申请对此不作限制。另外，需要说明的是，作为一种举例，如图2所示，夹臂部是一个部件集成，包括图2中整体结构的全部和一部分，本申请对此不作限制。
在本实施例中，如图1所示，手柄100包括至少两个；如图2和图3所示，夹臂包括固定夹臂201和活动夹臂202，活动夹臂202的数量与手柄100的数量相同，也就是至少为两个；如图1所示，每一个手柄100均设有联动部件；并在联动部件的驱动下，如图3和图4所示，一个手柄100控制一个活动夹臂202与固定夹臂201开合。
在上述技术方案中，当对创伤周围的组织及出血血管进行夹闭操作时，由于活动夹臂202的数量为多个，并且手柄100的数量也为多个，每个手柄100可以通过联动部件单独控制相应的活动夹臂202与固定夹臂201的开合，因而当创伤较大时，该种止血夹也能够适用，达到止血目的。此外，在该种技术方案中，通过增加手柄100及相应的活动夹臂202的数量，因而也结构简单，制造成本也较低。
此外，由于任两个所述手柄100之间的夹角不变，比如通过硬质材质或其他装置予以固定，因而任两个所述手柄100之间的夹角不会发生变化，这种结构在人手进行握持时操作更方便，从而能够更方便驱动滑块101，进而驱动夹臂的开合操作，更有利于创伤的夹闭操作。综上，本申请所提供的止血夹能够实现较大创口的夹闭固定，达到止血目的，并且结构简单，成本较低。
在上述技术方案中，可以做出进一步改进。比如，如图1所示，联动部件为滑块101，滑块101可移动套于手柄100的圆周外部，以便随着滑块101移动，带动活动夹臂202与固定夹臂201开合。具体的，该手柄100包括芯杆102，滑块101可以移动套于芯杆102的外部。在该种方案中，当对创口进行夹闭时，通过手操作滑块101滑动，然后滑块101通过一定的连接部件，将驱动力传递给固定夹臂201和活动夹臂202，因而能够非常容易地实现活动夹臂202与固定夹臂201的开合。
进一步的，如图1所示，手柄100的数量可以为两个，并呈Y型；滑块101的数量为两个，活动夹臂202的数量为两个；两个活动夹臂202分置于固定夹臂201的两侧。在该种技术方案中，手柄100的数量为两个，并且呈Y型，从而符合人手的生理结构，从而便于人手握持。在人手握持的基础上，便于驱动滑块101进行滑动。
进一步的，在上述结构中，可以做出具体设计。比如，两个手柄100可以为一体形成的部件。一体成型的结构可以便于手柄形成Y型的结构，并且在管材采用硬质材料时，该一体形成的Y型手柄也能够实现二者夹角不变的目的。
进一步的，从人机工程的角度出发，为了适应手术人员的操作，在本申请实施例中，任两个所述手柄100之间的夹角为0-180度，优选为为60-120度，其中，任两个所述手柄100之间的夹角为0度，表示两个手柄100之间相互平行，且具备一定间距。
此外，作为另一种实施例，如图1所示，手柄部还包括成Y型的三通管104，两个手柄100分别插入三通管104的两个分叉的管道中。该种结构设计能够方便地实现Y型手柄设计。并且，由于该三通管104的固定支撑作用，两个手柄100之间的夹角也不会改变。
请参考图5至图9，图5为图2中的装置的活动夹臂的结构示意图；图6为图2中的装置的夹座与固定夹臂的结构示意图；图7为图4中装置的主视图；图8为图7中的装置在夹臂打开时的结构示意图；图9为图2中的装置的连杆的结构示意图。
在上述任一种技术方案中，可以做出进一步改进。比如，如图1所示，夹臂部包括连接线300，连接线300在近侧端与滑块101连接，在远侧端与活动夹臂202连接。当工作时，滑块101滑动，从而带动连接线300运动，连接线300进而带动活动夹臂202运动，从而实现活动夹臂202与固定夹臂201之间的开合。需要说明的是，连接线300可以采用钢丝绳，当然也可以采用其他类型的绳索，本申请对此不作限制。
进一步的，如图7、图8和图9所示，夹臂部还包括连杆400，连接线300在远侧端通过连杆400与活动夹臂202连接。在该种设计中，工作时，通过滑块101滑动带动钢丝绳运动，钢丝绳进而带动连杆400运动，连杆400进而带动活动夹臂202运动，从而实现活动夹臂202与固定夹臂201之间的开合。
在上述技术方案中，还可以做出如下设计：
比如，如图6所示，夹臂部包括夹座500，夹座500沿轴向开设有第一滑槽501，如图9所示，连杆400的一端连接有活动销轴401；如图7和图8所示，活动销轴401 可移动设于第一滑槽501中；如图5所示，活动夹臂202设有与活动销轴401配合的圆形孔2021，以便活动夹臂202相对于活动销轴401转动。
此外，如图6、图7和图8所示，夹座500上设有固定销轴502，活动夹臂202上设有与固定销轴502配合的呈长条状的第二滑槽2024。
在上述技术方案中，工作时，当滑块101通过连接线300带动连杆400向上运动时，如图8所示，连杆400通过活动销轴401在夹座500的第一滑槽501中向上滑动；此时，活动销轴401与活动夹臂202上的圆形孔2021转动配合，并且夹座500上的固定销轴502配合于活动夹臂202的第二滑槽2024中，因而会带动活动夹臂202向上运动，通过由于第二滑槽2024与固定销轴502的限位作用，使得活动夹臂202发生顺时针转动，转动时是以活动销轴401为轴心转动，从而实现了活动夹臂202与活动夹臂202的张开。
工作时，如图7所示，当滑块101通过连接线300带动连杆400向下运动时，连杆400通过活动销轴401在夹座500的第一滑槽501中向下滑动；此时，活动销轴401与活动夹臂202上的圆形孔2021转动配合，并且夹座500上的固定销轴502配合于活动夹臂202的第二滑槽2024中，因而会带动活动夹臂202向下运动，通过由于第二滑槽2024与固定销轴502的限位作用，使得活动夹臂202发生逆时针转动，转动时是以活动销轴401为轴心转动，从而实现了活动夹臂202与活动夹臂202的关闭。
此外，在上述任一种方案中，还可以做出进一步改进。比如，如图5所示，圆形孔2021开设有缺口2022，活动夹臂202还设有尾部倒钩2023；如图6所示，夹座500内部设有固定台阶503；如图7所示，当活动销轴401脱离圆形孔2021时，撑开缺口2022，使得尾部倒钩2023卡在固定台阶503上。
在上述方案中，工作时，由于圆形孔2021设有缺口2022，因而当活动夹臂202被拉动时，可以迫使缺口2022处发生弹性变形，进而使得尾部倒钩2023
卡在夹座500的固定台阶503上，从而实现紧密的闭合，提升夹臂对创伤组织夹闭的稳定性和可靠性。
此外，如图2所示，夹臂部还包括固定帽600，及连接于夹座500与固定帽600之间的过渡帽700。进一步的，如图4所示，过渡帽700的圆周壁上均匀分布有三个连接孔701，该三个连接孔701配合有三爪卡扣702；如图5所示，连杆400的外部套有圆环，如图4所示，以便连杆400移动时下压固定环402，固定环402下压三爪卡 扣702，使得过渡帽700与夹座500分离。
此外，在本申请任一种技术方案中，还包括如下结构：
如图3、图4、图7和图8所示，连杆400将连接线300和活动销轴401进行连接，连杆400受到活动夹臂202和夹座500的限制，只能在指定平面内运动。在连杆400上，用于连接所述活动销轴401的部位的横向尺寸大于固定环402的内径尺寸，当连杆400受到钢丝绳的拉力时，连杆400往近侧端运动至固定环402处，将固定环402往近侧端压迫，从而带动三爪卡扣702运动从而实现过渡帽700和夹座500的分离。
如图2所示，
夹臂部还包括固定帽600和远端弹簧管800，固定帽600用于连接远端弹簧管800和过渡帽700的镶件，固定帽600和远端弹簧管800通过焊接工艺连接，固定帽600和过渡帽700的镶件之间通过台阶进行轴向约束，并可进行移动和旋转。
以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
