Description

穿刺系统及其控制手柄
本申请要求于2021年12月31日提交中国专利局、申请号为2021116832506、申请名称为“穿刺系统及其控制手柄”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,特别涉及一种穿刺系统及其控制手柄。
背景技术
心衰患者通常会表现为左房压力升高,进而导致肺淤血,使患者的生活质量严重受到影响。依据左心室射血分数(LVEF),心衰可分为射血分数降低的心衰(HFrEF)和射血分数保留的心衰(HFpEF)。研究结果表明,很多可改善HFrEF预后和存活率的药物(ARB,ACEI)对HFpEF无相似疗效,使得该类患者症状难以得到改善。
通过心房分流术在心房间建立分流通道,使右心系统的容量代偿性来缓解左心系统(特别是左心房)的压力载荷,可直接改善患者的血流动力学状况,降低左心房平均压力和肺毛细血管楔压,对改善HFrEF和HFpEF心衰患者的症状和预后具有较高的临床意义。主要方式包括传统的房间隔穿刺加球囊扩张和在心房间植入器械建立分流通道。
但是,目前的穿刺过程中,在需要控制穿刺功率输出的通断时,需要通过助手进行踩踏脚踏开关来控制,其弊端在于,助手需在施术者下达指令后方可踩下开关,这过程需要一定的时间,在这时间段内,心脏的搏动可能导致穿刺电极偏移目标位置,对病人造成极大的潜在危险,具有一定的局限性。

由上述技术方案可知,本申请至少具有如下优点和积极效果:
本申请提供的控制手柄,基于在外壳上设置控制机构,控制机构包括操作件和控制开关,如此通过对操作件的操作,能够使控制开关在导通状态和断开状态之间切换,在导通状态下,电极头与外部能源之间形成电路导通;在断开状态下,电极头与外部能源之间形成电路断开,因此施术者能够通过对操作件的操作即实现电路的通断,进而实现消融穿刺。相比现有的消融穿刺装置通断的开关一般需由助手进行踩踏脚踏开关来控制,其弊端在于,助手需在施术者下达指令后方可踩下开关,这过程需要一定的时间,在这时间段内,心脏的搏动可能导致穿刺电极偏移目标位置,对病人造成极大的潜在危险。而在手柄上加上控制机构,施术者可在对准位置后,直接立即操作控制机构,非常便捷,便于提升穿刺成功几率。

图1所示为本申请其中一实施例提供的穿刺系统的结构示意图。
参阅图1,穿刺系统800包括电极头1、套管2以及控制手柄3。
套管2包括内管21和套接在内管21外周的外管22。
外管22主要起支撑作用。外管22的材质包括但不限于聚醚醚酮(PEEK)、聚醚嵌段聚酰胺(PEBAX) 和尼龙(PA)中的至少一种。
内管21的远端伸出外管22,便于在穿刺时调整方向。内管21的远端套设于电极头1的外周,用于连接电极头1。内管21的材质包括但不限于聚醚嵌段聚酰胺(PEBAX)和尼龙(PA)中的至少一种,使内管21具有较好的延展性。
电极头1设置于套管2的远端,具体与内管21套接。示例性地,电极头1与内管21的远端通过热熔而熔接。
电极头1的远端为实心的无创伤尖端,近端为中空管,中空管内设有显影块填塞至尖端附近,以便于在手术中追踪电极头1的位置。电极头1的材质为导电金属材料。

以下通过各实施例具体介绍控制手柄。
第一实施例
请一并参阅图1至图5,在本申请第一实施例中,控制手柄4包括外壳41和设置在外壳41上的控制机构44。外壳41内设置有容置空间410。控制机构44包括控制开关440和操作件441。操作件441设置于外壳41上。控制开关440设置于容置空间410内。控制开关440用于与电极头1和外部能源电性连接。操作件441用于触发控制开关440处于导通状态或断开状态;在导通状态下,电极头1与外部能源之间形成电路导通。在断开状态下,电极头1与外部能源之间形成电路断开。
本申请提供的控制手柄4,基于在外壳41上设置控制机构44,控制机构44包括控制开关440和操作件441,如此通过对操作件441的操作,能够使控制开关440能够在导通状态和断开状态之间切换,在导通状态下,电极头1与外部能源之间形成电路导通,从而实现外部能源向电极头1输送能源,以进行消融穿刺或标测;在断开状态下,电极头1与外部能源之间形成电路断开,从而外部能源能够停止向电极头1输送能源,因此施术者能够通过对操作件441的操作即实现电路的通断,进而实现消融穿刺。相比现有的消融穿刺装置通断的开关一般需由助手进行踩踏脚踏开关来控制,其弊端在于,助手需在施术者下达指令后方可踩下开关,这过程需要一定的时间,在这时间段内,心脏的搏动可能导致穿刺电极偏移目标位置,对病人造成极大的潜在危险。而在手柄上加上控制机构,施术者可在对准位置后,直接立即操作控制机构,非常便捷,便于提升穿刺成功几率。
示例性地,在本实施例中,外壳41内部中空而具有容置空间410。具体地,外壳41包括上盖411和下壳412。上盖411和下壳412共同围设形成容置空间410。上盖411和下壳412可以通过但不局限于卡接、焊接、粘接、螺钉锁固等方式相互配合固定而固定在一起。本实施例中,上盖411和下壳412之间卡接连接。为了更清楚地描述,本申请在描述方位时,以外壳41的轴线水平延伸为参照,朝向地面的方向为下,背向地面的方向为上。其中,在图3中,由上盖411指向下壳412的方向为上,由下壳412指向上盖411的方向为下。
进一步地,外壳41的远端设有前胶套46。前胶套46与外壳41之间通过胶水粘接,且前胶套46套设 于套管2的外周,以降低内管、外管以及其他结构在术中弯折的风险,保证安全。
在一些实施例中,控制手柄4还包括能量接头42。外部能源通过能量接头42与电极头1电性连接,从而实现外部能源向电极头1输送能源,以对待测组织进行穿刺或标测。具体地,能量接头42设置于外壳41的近端,用于与外部能源电连接。其中,外部能源用于产生射频等消融能源。外部能源可以是,但不局限于射频发生器、脉冲发生器中一者或它们之间的组合,或其他能实现消融的能源,此处不做限定。
在一些实施例中,控制手柄4还包括供液机构43。供液机构43与外壳41的中部连接,并与伸入至容置空间410内的套管2连通。供液机构43包括供液管路431和阀门432。在本实施例中,供液机构43通过供液管路431与套管2连通,并通过阀门432的作用,以能够在术中注射液体而排尽套管2内的空气,并使流体进入流体通道进而进入体内。在其他实施例中,也可以没有供液机构43。
供液管路431的其中一端即远端与外壳41连接。具体地,外壳41上设置有开孔,该开孔与容置空间410相通,供液管路431设置于该开孔处,并伸入至容置空间410内而与套管2密封连接,以使供液管路431与流体通道相通。在本实施例中,供液管路431在容置空间内朝远端延伸,从而缩短了流体的输送距离及减小流体的流动阻力,进而提升了流体的输送效率。在一些实施例中,供液管路431在容置空间内还可以部分朝远端延伸,部分沿近端延伸。
具体地,在本实施例中,供液管路431在容置空间410内的远端与外壳41的远端具有间隔,套管2的近端伸入容置空间410内并与供液管路431连通,而实现供液管路431与流体通道的相通。套管2的近端与供液管路431粘接。
阀门432设置于供液管路431的近端。本实施例中,阀门432为三通阀,包括第一接口、第二接口和第三接口。第一接口与供液管路431连通,进而实现与套管2以及流水通道连通,第二接口用于通过一管路与注射器连接,第三接口通过负压管路与负压器连接。在其它一些实施例中,阀门432也可以为单通阀、二通阀或其它多通阀。需要说明的是,阀门432可以根据穿刺手术的需求来设计阀门432的接口数量,本申请不做具体限定,在一些实施例中,阀门432可以设置在供液设备上,即阀门432可以不设置在供液管路431上。例如,阀门432通过TPU软管与供液管路431连接。
请一并参阅图1和图6,控制开关440包括第一线缆443、第二线缆444、第一连接件445和第二连接件446。第一连接件445和第二连接件446均位于容置空间410内,且第一连接件445和第二连接件446之间具有间隔。第一线缆443的远端与第一连接件445电性连接,第二线缆444的远端与第二连接件446电性连接,第一线缆443的近端和第二线缆444的近端均与外部能源电性连接。在操作件441抵压第一连接件445和/或第二连接件446时,第一连接件445和第二连接件446能够接触,且第一连接件445和第二连接件446接触时实现控制开关440处于导通状态。在第一连接件445和/或第二连接件446处于释压状态(即抵压部448与第一连接件445和/或第二连接件446的脱离抵压)时,第一连接件445和第二连接件446能够相互隔离设置,从而实现控制开关440处于断开状态。
在一些实施例中,操作件441相对外壳41活动设置。操作件441包括用于抵压第一连接件445和/或第二连接件446的抵压部448。操作件441能够在外力作用下驱动抵压部448抵压第一连接件445和/或第二连接件446。操作件441能够在外力作用下移动,使控制开关440实现电路导通,进而实现电极头1与外部能源的导通,即通过外力对操作件441的作用而控制电极头1与能量接头42之间的电性通断,进而控制穿刺系统与外部能源之间的电性通断,使施术者通过手即可操作,非常方便。
在其它一些实施例中,操作件441相对外壳41固定设置。具体地,控制机构44还包括设置于操作件441上的感应件和与感应件电性连接的驱动件。感应件用于响应在操作件441上输入的预设触控操作而产生触控信号,驱动件用于根据触控信号驱动抵压部448抵压第一连接件445和/或第二连接件446,从而更智能化地控制电极头1与外部能源之间的电路通断。可以理解地,感应件与操作件441可以一体成型;或者,可以相互独立设置。感应件可以为但不局限于压力传感器、指纹传感器、距离传感器、光耦传感器等 等。
示例性地,在本实施例中,操作件441相对外壳41沿外壳41的径向移动,即操作件441能够在外力作用下在容置空间410内移动,使第一连接件445和第二连接件446接触而实现电路导通。具体地,操作件441沿外壳41的径向方向上下移动,即在施术者操作操作件441时,用手按压或松开该操作件441,即可实现电路通断。
操作件441相对外壳41外露,从而方便用户操控操作件441。示例性地,在本实施例中,操作件441的至少部分结构伸出至外壳41外。具体地,外壳41的上盖411上开设有一开口,操作件441部分结构位于容置空间410内,其余部分结构通过该开口伸出容置空间410外。在其它实施例中,操作件441还可以全部位于容置空间410内。例如,操作件441的外周略低于或齐平于外壳41的外周,能够较好的避免误操作而按压操作件441。
在一些实施例中,外壳41对应操作件441的位置处还可以设置一保护盖,以保护操作件441。该保护盖与外壳41连接,并能够相对于操作件441开合。在保护盖关闭时,操作件441位于保护盖与外壳41共同围合形成的保护空间内,无法对操作件441进行操作,避免了误操作。在保护盖打开时,可以对操作件441进行操作。
可选地,保护盖与外壳41转动连接。例如,保护盖可以但不局限于与开口的侧壁之间铰链连接或者通过转轴转动连接而实现开合。保护盖与外壳41还可以通过卡扣、螺接等方式可拆卸连接在一起,本申请不作具体限定。
控制机构44还包括导电件442,导电件442远端伸出外壳41并用于与电极头1电性连接,导电件442近端与控制开关440或外部能源电性连接。其中,导电件442的近端可以通过第一连接件445或第二连接件446与述控制开关440或外部能源电性连接;或者,导电件442的近端可以通过第一线缆443或第二线缆444与述控制开关440或外部能源电性连接;或者,导电件442的近端可以直接与外部能源电性连接。示例性地,在本实施例中,导电件442设置于控制开关440和能量接头42之间。具体地,导电件442的远端与能量接头42电性连接,导电件442的近端与第一连接件445连接。可选地,导电件442位于套管2和供液管路431内。
示例性地,在本实施例中,导电件442配置为导电丝。导电丝的远端与电极头1固定连接。导电丝可以包括多个导电段。可以理解地,为了使本领域技术人员更好地理解导电件442,导电件442以导电丝为例进行详细说明。需要说明的是,导电件442为导电丝仅用于进行说明,本申请不做具体限定,例如,导电件442的产品类型也可以根据实际需要进行设定。例如,在其它一些实施例中,导电件442配置为导电管。其中,导电管与电极头1可以一体成型;或者,导电管可以套接于电极头1外;或者,电极头1可以与导电管的远端面固定连接。
需要说明的是,导电件442用于与第一连接件445以及电极头1电性连接的端部的其余部分的外周均包覆有绝缘材料。即导电件442的两端端部用于电性连接,其余部分均包覆有绝缘材料。
本实施例中,第一线缆443和第二线缆444的数量分别为一根。需要说明的是,第一线缆443和第二线缆444的数量仅仅用于进行说明,第一线缆443和第二线缆444的数量可以依据实际而设置。例如,在一些实施例中,第一线缆443和第二线缆444的数量还可以为多根。
第一连接件445和第二连接件446均位于容置空间410内,且两者之间具有间隔。本实施例中,第一连接件445和第二连接件446均位于供液管路431的远端,并与供液管路431之间具有间隔。即套管2沿外壳41的轴向由远端至近端穿过第一连接件445和第二连接件446所在的位置,并继续向近端延伸,而与供液管路431连通。也就是说,第一连接件445以及第二连接件446与穿刺系统的流体通道在外壳41的容置空间410内互不干涉。
可选地,在一些实施例中,第一连接件445和/或第二连接件446包括与抵压部448对应设置的触发部 449。抵压部448用于抵压触发部449,以使得第一连接件445的触发部449与第二连接件446接触。在另一些实施例中,抵压部448用于抵压触发部449,以使得第二连接件446的触发部449与第一连接件445接触。在其它一些实施例中,抵压部448用于抵压触发部449,以使得第一连接件445的触发部449与第二连接件446的触发部449接触。
具体地,请参阅图6,第一连接件445包括连接片4451和与连接片4451间隔设置的第一引脚4452。第二连接件446包括基座4461和第二引脚4462。基座4461对应第一连接件445设置,并位于连接片4451背离操作件441的一侧。第一引脚4452和第二引脚4462间隔地设置在基座4461上,第一引脚4452与第一线缆443的远端电性连接,第二引脚4462与第二线缆444的远端电性连接,基座4461上设置有两个触点4463,两个触点4463分别与第一引脚4452和第二引脚4462电性连接,且间隔设置。其中,触发部449即为连接片4451。操作件441能够在外力作用下驱动连接片4451与两个触点4463接触,以实现控制开关440处于导通状态。具体地,在本实施例中,基座4461包括间隔设置的第一触点和第二触点,第一触点与第一引脚4452电性连接,第二触点与第二引脚4462电性连接。
可选地,在一些实施例中,连接片4451具有弹性,以确保连接片4451发生形变后与触点4463充分接触,以确保在连接片4451受压时,连接片4451与两个触点4463之间能够形成良好的电接触。在其它一些实施例中,连接片4451可以是刚性的。在本实施例中,操作件441的抵压部448与连接片4451连接。可选地,抵压部448固定连接于连接片4451的中部,从而确保连接片4451的两端受力均衡,进而提升连接片4451与两个触点4463之间连接的稳定性和可靠性。在一些实施例中,抵压部448还可以固定连接于连接片4451除中部的其它位置,本申请不做具体限定。操作件441在外作用力下抵压连接片4451时,连接片4451朝向基座4461运动,连接片4451的两端分别抵接基座4461的触点4463。
在一些实施例中,连接片4451包括与操作件441连接的连接片本体和设置在连接片本体在壳体41的长度方向的两端的延伸部。延伸部的延伸方向平行于触点4463所在平面,以确保连接片4451与两个触点4463之间的接触面积,提高电接触的可靠性和稳定性。
连接片4451配置为片状结构,从而简化连接片441的结构,减轻重量,节省空间。
示例性地,本实施例中,连接片4451的外形呈弧形。具体地,连接片4451朝操作件441弯曲,即连接片4451的凸面朝向操作件441。连接片4451沿外壳41的轴向弯曲延伸。在一些实施例中,连接片4451的外形还可以呈其它形状,例如连接片4451呈中间凸起两边平整,例如Ω型、“几”字形等,本申请不作具体限定。
触点4463在基座4461上朝向连接片4451向外凸伸。第一引脚4452与第一线缆443电性连接,第二引脚4462与第二线缆444电性连接。在连接片4451与两个触点4463接触时,第一引脚4452和第二引脚4462电性连接,控制开关440处于导通状态;在连接片4451与两个触点4463隔离时,第一引脚4452和第二引脚4462断开连接,控制开关440处于断开状态。本实施例中,导电件442的近端与第一线缆443电性连接,进而与第一引脚4452电性连接,实现导电件442与第一连接件445的电性连接。

在一些实施例中,可通过操作件的内部结构,实现按动操作件一次即可使第一连接件与第二连接件持续导通,再次按动操作件可使第一连接件与第二连接件分离。
由上述技术方案可知,本申请至少具有如下优点和积极效果:
本申请的控制手柄包括外壳和控制机构,控制机构包括操作件以及控制开关,通过对操作件的操作,使控制开关实现电路导通,进而实现电极头与外部能源的导通。即施术者能够通过对操作件的操作即实现电路的通断,进而实现消融穿刺。相比现有的消融穿刺装置通断的开关一般需由助手进行踩踏脚踏开关来控制,其弊端在于,助手需在施术者下达指令后方可踩下开关,这过程需要一定的时间,在这时间段内,心脏的搏动可能导致穿刺电极偏移目标位置,对病人造成极大的潜在危险。而在手柄上加上控制机构,施术者可在对准位置后,直接立即操作控制机构,非常便捷,便于提升穿刺成功几率。
需要说明的是,以上各个实施方式中的具体技术方案,可以相互适用。
虽然已参照几个典型实施方式描述了本申请,但应当理解,所用的术语是说明和示例性、而非限制性的术语。由于本申请能够以多种形式具体实施而不脱离申请的精神或实质,所以应当理解,上述实施方式不限于任何前述的细节,而应在随附权利要求所限定的精神和范围内广泛地解释,因此落入权利要求或其等效范围内的全部变化和改型都应为随附权利要求所涵盖。
