技术领域technical field
本发明涉及医疗器械技术领域,尤其涉及一种夹钳闭合组件和施夹器。The invention relates to the technical field of medical instruments, in particular to a clip closing assembly and a clip applier.
背景技术Background technique
外科手术过程中为充分暴露手术视野,需要对目标组织周围血管进行结扎,以阻止出血。止血技术已经成为了外科手术基本操作技术的核心之一,人体任何部位的外科操作几乎无一例外地涉及到出血与止血,一般使用施夹器闭合止血。In order to fully expose the surgical field during the surgical operation, it is necessary to ligate the blood vessels around the target tissue to prevent bleeding. Hemostasis technology has become one of the cores of basic surgical techniques. Surgical operations on any part of the human body almost without exception involve bleeding and hemostasis. Clip appliers are generally used to close hemostasis.
在施夹器的使用过程中,夹闭止血夹会出现止血夹两夹臂交叉、扭曲和异形的现象,从而造成止血夹对血管的结扎效果不佳,甚至无法阻止出血。During the use of the clip applier, when the hemostatic clip is clamped, the two arms of the hemostatic clip will cross, twist and be deformed, resulting in poor ligation effect of the hemostatic clip on blood vessels, or even failure to stop bleeding.

(三)有益效果(3) Beneficial effects
本发明的有益效果是:The beneficial effects of the present invention are:
1、通过在第一钳臂的底部开设第一插槽,在第二钳臂的底部开设第二插槽,在击发片闭合夹钳的过程中令击发片的远端始终插入第一插槽和第二插槽并沿第一插槽和第二插槽向远移动,借助于击发片作用于第一插槽和第二插槽来约束第一钳臂和第二钳臂,当第一挤压力方向和第二挤压力方向相互交叉时,击发片通过第一插槽约束第一钳臂,击发片通过第二插槽约束第二钳臂,使第一钳臂和第二钳臂之间不会发生相对错位,从而避免了夹钳闭合组件夹闭止血夹出现的止血夹两夹臂交叉、扭曲和异形的现象,提高手术成功率。1. By opening the first slot at the bottom of the first clamp arm and opening the second slot at the bottom of the second clamp arm, the distal end of the firing piece is always inserted into the first slot during the process of closing the clamp of the firing piece and the second slot and move far along the first slot and the second slot, and constrain the first pincer arm and the second pincer arm by means of the firing piece acting on the first slot and the second slot, when the first When the extrusion force direction and the second extrusion force direction cross each other, the firing piece constrains the first tong arm through the first slot, and the firing piece constrains the second tong arm through the second slot, so that the first tong arm and the second tong arm There will be no relative misalignment between the arms, thereby avoiding the phenomena of crossing, twisting and abnormal shape of the two clamping arms of the hemostatic clamp that occur when the clamp closing component clamps the hemostatic clamp, and improves the success rate of the operation.
2、通过在第一连接部与第一底板之间设置第一连接壁来形成第一插槽,保证第一插槽强度的同时避免了为形成第一插槽在第一闭钳部与第一底板之间设置连接壁;同样通过在第二连接部与第二底板之间设置第二连接壁来形成第二插槽,保证第一插槽强度的同时避免了为形成第二插槽在第二闭钳部与第二底板之间设置连接壁;如此,便于上述击发片与第一插槽和第二插槽的配合,避免在闭合夹钳的过程中,击发片向远移动,侧壁(第一侧壁和第二侧壁)与支撑底板的连接处与连接壁发生干涉。2. The first slot is formed by setting the first connecting wall between the first connecting part and the first bottom plate, which ensures the strength of the first slot and avoids the need for forming the first slot between the first closed clamp part and the second slot. A connecting wall is set between a bottom plate; the second slot is formed by setting the second connecting wall between the second connecting part and the second bottom plate, which ensures the strength of the first slot while avoiding the need to form the second slot. A connecting wall is set between the second closed jaw part and the second bottom plate; in this way, it is convenient for the above-mentioned firing piece to cooperate with the first slot and the second slot, and it is avoided that the firing piece moves far away during the process of closing the clamp. The connection of the walls (the first side wall and the second side wall) to the support base interferes with the connection wall.

为清楚说明本发明实际解决的技术问题,下面通过一个示例性夹钳闭合组件和一个示例性施夹器的夹仓装置来进行解释。然而应当理解,本发明提出的夹钳闭合组件和施夹器的夹仓装置不应被这里阐述的示例性夹钳闭合组件和示例性施夹器的夹仓装置所限制;相反,提供这些示例是为了能够更清楚、透彻地理解本发明,并且能够将本发明的范围完整地传达给本领域的技术人员。In order to clearly illustrate the technical problem actually solved by the present invention, an exemplary clip closing assembly and an exemplary clip applier clip bin device are explained below. It should be understood, however, that the disclosed clip closure assemblies and clip applier cartridge arrangements should not be limited by the exemplary clip closure assemblies and clip applier cartridge arrangements set forth herein; rather, these examples are provided It is for the purpose of being able to understand the present invention more clearly and thoroughly, and to fully convey the scope of the present invention to those skilled in the art.
如图1和图2所示,该示例性夹钳闭合组件包括夹钳1和用于闭合夹钳的击发片2。夹钳1包括夹钳固定板11,夹钳固定板11的远端具有沿远近方向延伸的第一钳臂12和第二钳臂13,第一钳臂12和第二钳臂13从左至右依次排列,第一钳臂12和第二钳臂13之间形成开口朝向远方的钳口。击发片2的远端具有位于夹钳下方的支撑底板21,在支撑底板21的左右两侧分别设置有向上的第一侧壁22和向上的第二侧壁23,第一侧壁22和第二侧壁23的长度小于支撑底板21的长度且位于支撑底板21的远端部,第一钳臂12和第二钳臂13位于第一侧壁22与第二侧壁23之间,并且第一侧壁22靠近第一钳臂12,第二侧壁23靠近第二钳臂13。一般来说,第一侧壁22和第二侧壁23在左右方向上并排设置。待夹闭的止血夹卡在钳口内,击发片2闭合夹钳的过程中,击发片2向远移动,第一侧壁22挤压第一钳臂12向第二钳臂13移动,第二侧壁23挤压第二钳臂13向第一钳臂12移动,直至钳口完全闭合,即夹闭止血夹。As shown in FIGS. 1 and 2 , the exemplary clamp closure assembly includes a clamp 1 and a
击发片2复位的过程中,击发片2向近移动,击发片2对第一钳臂12和第二钳臂13的挤压作用放松,当第一钳臂12和第二钳臂13均为弹性件时,可以利用弹性件的恢复力,令第一钳臂12向远离第二钳臂13的方向移动,第二钳臂13向远离第一钳臂12的方向移动,直至击发片2复位完成,此时第一钳臂12和第二钳臂13恢复至初始位置,即钳口张开复位。During the reset process of the
如上述结构设计的夹钳闭合组件,实际使用过程中(即实际击发片2闭合夹钳的过程中)会出现止血夹的两夹臂交叉、扭曲和异形的现象。申请人经过研究发现,造成止血夹产生上述闭合不良现象的主要因素为:击发片2闭合夹钳的过程中,第一侧壁22作用于第一钳臂12的上的第一挤压力较复杂,第二侧壁23作用于第二钳臂13上的第二挤压力较复杂,存在第一挤压力和第二挤压力方向相互交叉的情形,如此夹闭钳口的过程中,第一钳臂12和第二钳臂13相互靠近的同时,第一钳臂12和第二钳臂13会产生不同程度的向上或向下翘起,从而造成待夹闭的止血夹的两夹臂交叉、扭曲和异形,成夹不良。For the clip closure assembly designed with the above structure, during actual use (that is, during the
为减少夹闭钳口过程中待夹闭止血夹成夹不良的现象,在一示例性施夹器的夹仓装置中,包括压块3和用于容纳夹钳近端和击发片2近端的套筒4,压块3位于夹钳的上方,压块3的近端插入并固定在套筒4内,压块3压紧夹钳。通过压块3对夹钳向上限位,减少夹闭钳口过程中待夹闭止血夹成夹不良的现象。然而申请人发现,在上述设计的施夹器夹仓装置中,夹钳的远端和击发片2的远端通常为悬臂梁结构,击发片2闭合夹钳的过程中,由于第一侧壁22作用于第一钳臂12上的第一挤压力和第二侧壁23作用于第二钳臂13上的第二挤压力均较复杂,常存在令击发片2远端和/或夹钳远端向下翘起的情形,如此在第一挤压力方向和第二挤压力方向相互交叉时,第一钳臂12和第二钳臂13依然会产生不同程度的向上或向下翘起,造成待夹闭止血夹的两夹臂交叉、扭曲和异形,成夹不良。In order to reduce the bad clamping of the hemostatic clip to be clamped in the process of clamping the jaws, in the clamping device of an exemplary clip applier, a
综上,不管是在示例性夹钳闭合组件中,还是在示例性施夹器的夹仓装置中,均是由于夹闭钳口过程中存在第一挤压力方向和第二挤压力方向相互交叉的情形,使第一钳臂12和第二钳臂13发生相对错位,才造成待夹闭的止血夹的两夹臂交叉、扭曲和异形。To sum up, whether it is in the exemplary clamp closing assembly or in the clamping device of the exemplary clip applier, it is due to the existence of the first extrusion force direction and the second extrusion force direction in the process of clamping the jaws The situation of intersecting with each other makes the
为此,本发明提出了一种夹钳闭合组件。为了更好的解释本发明,以便于理解,下面结合附图,通过具体实施方式,对本发明作详细描述。虽然附图中显示了本发明的示例性实施例,然而应当理解,可以以各种形式实现本发明而不应被这里阐述的实施例所限制。To this end, the present invention proposes a clamp closure assembly. In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

夹钳和击发片2具有如上面描述的结构设计,不再赘述。此外,如图3和图4所示,第一钳臂12的底部开设有第一插槽15,第二钳臂13的底部开设有第二插槽17,第一插槽15和第二插槽17均沿远近方向延伸;击发片2闭合夹钳的过程中,支撑底板21的远端左侧部始终自右向左插入第一插槽15并沿第一插槽15向远移动,支撑底板21的远端右侧部始终自左向右插入第二插槽17并沿第二插槽17向远移动。The clamp and the
如此设置第一插槽15和第二插槽17,在击发片2闭合夹钳的过程中令击发片2的远端始终插入第一插槽15和第二插槽17并沿第一插槽15和第二插槽17向远移动,借助于击发片2作用于第一插槽15和第二插槽17来约束第一钳臂12和第二钳臂13,当第一挤压力方向和第二挤压力方向相互交叉时,击发片2通过第一插槽15约束第一钳臂12,击发片2通过第二插槽17约束第二钳臂13,使第一钳臂12和第二钳臂13之间不会发生相对错位,从而避免了夹钳闭合组件夹闭止血夹出现的止血夹两夹臂交叉、扭曲和异形的现象,提高手术成功率。The
需要说明的是,如上设置的夹钳闭合组件,在夹闭过程中,由于第一挤压力和第二挤压力的作用,会出现夹钳远端和击发片2远端整体向上(下)翘起和/或扭转的情形,但是第一钳臂12和第二钳臂13之间并没有发生相对错位,因此并不影响夹钳对止血夹的稳定闭合。It should be noted that, in the clamp closing assembly as set up above, during the clamping process, due to the action of the first extrusion force and the second extrusion force, the distal end of the clamp and the distal end of the
优选地,击发片2能够在由近至远排列的近端初始位置和远端终止位置之间移动;击发片2从近端初始位置向远端终止位置移动的过程中,支撑底板21的远端左侧部始终自右向左插入第一插槽15并沿第一插槽15向远移动,支撑底板21的远端右侧部始终自左向右插入第二插槽17并沿第二插槽17向远移动。如此,令击发片2从一开始到最终结束都插入第一插槽15和第二插槽17,保证了击发片2夹闭夹钳的顺利、稳定,避免在实际使用过程中出现让击发片2插入第一插槽15和第二插槽17的过程,从而引起击发片2插入第一插槽15和第二插槽17不便、夹闭失败的问题。Preferably, the
需要说明的是,近端初始位置可以是击发片2闭合夹钳过程中击发片2的初始位置,远端终止位置可以是击发片2闭合夹钳过程中击发片2的终止位置。当然,近端初始位置也可以位于击发片2闭合夹钳过程中击发片2初始位置的近侧,远端终止位置也可以位于击发片2闭合夹钳过程中击发片2终止位置的远侧。It should be noted that the proximal initial position may be the initial position of the
在本实施例提出的夹钳闭合组件中,支撑底板21的远端左侧部插入第一插槽15后,在垂直于支撑底板21远端左侧部所在平面方向上留下的第一插入间隙越小,越利于击发片2通过第一插槽15约束第一钳臂12,但是第一插入间隙也不能过小,以影响击发片2向远移动。同样,支撑底板21的远端右侧部插入第二插槽17后,在垂直于支撑底板21远端右侧部所在平面方向上留下的第二插入间隙越小,越利于击发片2通过第二插槽17约束第二钳臂13,但是第二插入间隙也不能过小,以影响击发片2向远移动。In the clamp closure assembly proposed in this embodiment, after the left side of the distal end of the
优选地,支撑底板21具有向远伸出第一侧壁22和第二侧壁23的第一作用位211;击发片2闭合夹钳的过程中,第一作用位211的远端左侧部始终自右向左插入第一插槽15并沿第一插槽15向远移动,第一作用位211的远端右侧部始终自左向右插入第二插槽17并沿第二插槽17向远移动。如此,通过设置向远伸出第一侧壁22和第二侧壁23的第一作用位211来插入第一插槽15和第二插槽17,方便支撑底板21与第一插槽15和第二插槽17的配合,同时进一步增强了支撑底板21对第一钳臂12和第二钳臂13的向下限位作用。Preferably, the
