Description
技术领域
本发明涉及一种外科器械,具体而言,涉及一种外科器械,属于医疗器械领域。
背景技术
外科器械为医疗手术中的手术工具,缝合器械为外科器械的一种,其是医学上使用的、替代手工缝合的设备,主要工作原理是利用钛钉对组织进行离断或吻合,类似于订书机。缝合器械包括一对相配合的细长钳口构件,钳口构件可适于插入患者体内以缝合和/或切割组织,钳口构件可支撑容纳钉仓组件。目前,现有的钉仓组件包括钉仓本体和设置在钉仓本体内的缝合钉,钉仓本体内设置有若干用于收纳缝合钉的缝钉腔,钉仓本体包括顶端面,顶端面上设有由所述缝钉腔贯穿顶端面形成的出钉口。缝合时,顶端面与被缝合组织接触,缝合器械内的切割刀推动钉仓内的推钉件向上移动以使钉仓内的缝合钉从缝钉腔内移出进而缝合(即缝合钉出钉)。
为了防止缝合钉在存储、运输或装配到外科器械的端部执行器的过程中从缝钉腔脱落,现有的外科器械的钉仓组件的钉仓保护盖与钉仓本体表面完全贴合。由于缝合钉的钉尖与钉仓本体的顶端面齐平,缝合钉的钉尖与钉仓保护盖接触,且缝合钉的钉尖是锐利的,通常会因为钉仓组件在存储、运输或装配过程中,因挤压或晃动等原因造成部分缝合钉的钉尖略嵌入钉仓保护盖上;这样一来,当将钉仓组件安装到外科器械的端部执行器内、取下所述钉仓保护盖时,钉仓保护盖会连同部分缝合钉一起脱离钉仓本体。这样,在对患者伤口进行缝合时,由于部分缝合钉的缺失,伤口不能被有效缝合,导致患者伤口出血,不利于手术的顺利进行及术后患者的伤口愈合。
发明内容
本发明旨在提供一种能防止缝合钉脱落的钉仓组件及其外科器械,本发明通过以下技术方案实现:

进一步地,所述钉仓保护盖还包括连接部,所述连接部用于可拆卸地连接所述隔挡板与所述钉仓本体。
进一步地,所述空间的高度小于所述缝合钉的高度。
优选地,所述隔挡板上设有凸起,所述凸起形成所述阻隔部。
进一步地,所述凸起为长方体、环形体或截面不是多边形的柱体。
进一步地,所述长方体包括条状体。
优选地,所述阻隔部与所述隔挡板一体成型或固定连接或可拆卸地连接。
进一步地,所述隔挡板上设有至少两个所述阻隔部,至少两个所述阻隔部沿所述隔挡板的中心轴线对称设置。
进一步地,所述隔挡板前端的厚度大于所述隔挡板后端的厚度。

具体实施方式
下面详细描述本发明的实施例,所述实施例的示例在附图中示出。在本发明的描述中,需要理解的是,术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”、“顺时针”、“逆时针”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系。

下面通过参考附图描述的实施例是示例性的,旨在用于解释本发明,而不能理解为对本发明的限制。
如图1所示,本发明实施例的外科器械1000包括手柄组件9、杆身组件8、端部执行器7以及钉仓100。手柄组件9与杆身组件8连接,杆身组件8的一端与端部执行器7连接。进一步地,端部执行器7包括抵钉座71和钉仓座72,抵钉座71可枢转地与钉仓座72连接,其具有打开位置和闭合位置并可在打开位置和闭合位置之间选择性地运动。钉仓组件100包括钉仓本体1和钉仓保护盖2,进一步地,钉仓组件100还包括钉腔12、缝合钉3、缝合钉驱动器4、推钉块5、推钉槽13及支撑件6。为了便于描述本发明和简化描述,在本发明实施例中,基于图3所示的方位或位置关系,将靠近所述钉仓插入端11的方向称为“前”和“前端”;将远离所述钉仓插入端11的方向称为“后”和“后端”;将靠近钉仓保护盖2的方向称为“上”和“上面”,将靠近支撑件6的方向称为“下”和“下面”,将推钉块5的运动轨迹所在的直线方向称为“长度”方向。
为了避免缝合钉3在存储、运输过程中因挤压或受外力而从钉腔12上端脱离钉仓本体1,如图1所示,未使用前,本发明实施例的钉仓组件100的钉仓保护盖2可拆卸地安装在钉仓本体1上。将钉仓组件100装配到外科器械的端部执行器内,如图2所示,取下钉仓保护盖2后,闭合所述端部执行器后即可进行外科手术的缝合操作。
外科器械1000的端部执行器7包括协同操作的钉仓座71及抵钉座72,所述抵钉座71可枢转地与所述钉仓座72连接,所述抵钉座71具有打开位置和闭合位置,并可在打开位置和闭合位置之间选择性地运动。当所述抵钉座71处于打开位置时,将钉仓组件100装入外科器械的端部执行器7内,如图2所示,外科器械1000的钉仓组件100装入端部执行器7;参考图3,钉仓组件100安装到位时,支撑件6与钉仓座72贴合;接着,如图4所示,先从钉仓组件100的前端将钉仓保护盖2向上移动,取下钉仓保护盖2;如图5及图6所示,取下钉仓保护盖2后,将所述抵钉座71运动到闭合位置即可闭合端部执行器7。关于钉仓座及抵钉座的连接方式,以及端部执行器与钉仓组件100的位置和连接关系,均与现有技术相同或相近,此处不作详细阐述。当外科器械1000的端部执行器7进入患者体内后,打开所述抵钉座71,当目标组织位于端部执行器7的钉仓座72及抵钉座71之间时,闭合所述抵钉座71、进而闭合所述端部执行器7,即可进行外科手术的缝合操作。
参考图8,钉仓本体1内上下贯通设置若干通孔,所述通孔形成钉腔12,缝合钉驱动器4的一部分与缝合钉3位于所述钉腔12内,钉仓本体1的后端设有推钉块5。由于缝合钉驱动器4的一部分设置在钉腔12内,钉腔12限定该缝合钉驱动器4仅能相对钉仓本体1上下移动,当推钉块5的凸轮部向缝合钉驱动器4的导向面施加作用力时,缝合钉驱动器4与缝合钉3仅能相对钉仓本体1向上移动。钉仓本体1的下方还设有支撑件6,既可以防止缝合钉驱动器4脱离钉仓本体1,又能增强钉仓本体1的强度。钉仓本体1还包括顶端面14和与顶端面14相背设置的底端面15,顶端面14与底端面15相互平行;钉仓本体1的上方有钉仓保护盖2。在端部执行器闭合的前提下,受外力的作用,推钉块5从钉仓本体1的后端向钉仓本体1的前端运动,推钉块5在运动的过程中推动缝合钉驱动器4在钉腔12内向上移动,从而使缝合钉3向上移动、刺透患者的组织,并缝合患者的伤口,直至缝合钉3脱离钉腔12。至于如何打开或闭合所述端部执行器均与现有技术相同或相近,此处不作详细阐述。具体地,缝合钉3包括钉尖和固定端,所述钉尖的锐利结构有利于缝合钉3更容易地刺入人体组织,所述固定端呈直线型且与顶端面14平行。未被击发时,缝合钉3位于钉腔12内,且所述钉尖与钉仓本体1的顶端面14齐平,缝合钉3大致呈“U”字形,缝合钉3的所述固定端位于缝合钉驱动器4内。
缝合钉驱动器4包括缝合钉容置槽和导向面,所述缝合钉容置槽用于容置缝合钉3的固定端,每个钉腔12内还设有一个所述缝合钉容置槽;也就是说,每个钉腔12内设有一个缝合钉3和一个对应的缝合钉容置槽。每个缝合钉驱动器4可以有一个缝合钉容置槽,这样每个缝合钉驱动器4可容置一个缝合钉3;或者,每个缝合钉驱动器4也可以有两个缝合钉容置槽,这样每个缝合钉驱动器4可容置两个缝合钉3。每个缝合钉驱动器4的结构及包含缝合钉容置槽的数量还可以根据需要变化,能满足容置并推动缝合钉3即可,此处不进行一一举例说明。受外力的作用下,推钉块5可以从钉仓本体1的后端运动到钉仓本体1的前端,在运动过程中,推钉块5的推钉面与缝合钉驱动器4的下方的导向面接触,导向面受力后使缝合钉驱动器4向上移动进而推动缝合钉容置槽在钉腔12内向上移动,进而带动钉腔12内的缝合钉3从其未击发位置向击发位置运动。所述支撑架6与所述钉仓本体1固定连接,用以支撑缝合钉驱动器4及推钉块5,以防止缝合钉驱动器4或推钉块5脱离钉仓本体1,且增强了钉仓本体1的强度。
如图9至图11所示,所述钉仓保护盖2包括隔挡板21、连接部和阻隔部24(在此实施例中,钉仓本体1上不设置阻隔部)。连接部包括第一卡钩部22和第二卡钩部23;阻隔部24与第一卡钩部22、第二卡钩部23均位于隔挡板21的隔挡面211上。隔挡面211上至少设有两个所述阻隔部24,阻隔部24沿所述隔挡板21的中心轴线对称设置,布置在隔挡面211上。第一卡钩部22还设有卡钩221。钉仓保护盖2包括至少两个第一卡钩部22,且至少两个所述第一卡钩部22沿钉仓保护盖2的中心轴线对称设置,对应地,钉仓本体1上设有至少两个卡槽16,且至少两个所述卡槽16沿钉仓本体1的中心轴线对称设置;卡钩221与卡槽16相配合以使隔挡板21固定在所述钉仓本体1上。第二卡钩部23为隔挡板21的部分边缘向下延伸形成,且与所述隔挡板21垂直,钉仓保护盖2包括至少两个第二卡钩部23,两个第二卡钩部22沿钉仓保护盖2的中心轴线对称设置,且两个第二卡钩部22之间的距离大致等于钉仓本体1上表面的宽度,这样,钉仓本体1被固定在两个第二卡钩部23之间,防止钉仓保护盖2相对于钉仓本体1移动,既可以将钉仓保护盖2定位并与钉仓本体1可拆卸连接,又便于拆卸。
钉仓本体1前方的插入端11呈楔形,钉仓保护盖2的隔挡板21的前端为一斜面,所述斜面与楔形插入端11配合,第一卡钩部22的卡钩221位于隔挡板21的前端,卡钩221与卡槽16卡接;第二卡钩部23与钉仓本体1的侧面接触,当需取下钉仓保护盖2时,隔挡板21前端的受力较大,隔挡板21前端的厚度大于隔挡板21后端的厚度,这样的设计使用较少材料保证了隔挡板21的强度满足安装及拆卸要求。
为了便于缝合时穿透患者的组织,缝合钉3的钉尖设计成锐利的尖端;未被击发时,缝合钉3位于钉腔12内,且缝合钉3的钉尖与钉仓本体1的顶端面14齐平。阻隔部24位于隔挡板21上,具体地,所述阻隔部24位于所述隔挡面211上,且与所述隔挡面211垂直,阻隔部24的高度小于所述缝合钉3的高度,能在缝合钉3未被击发时,很好地将其封堵在钉仓本体1内;优选地,阻隔部24的高度为0<h≤1mm,而吻合钉的高度为1.5≤H≤10mm,进一步地,吻合钉的高度为2≤H≤6mm。阻隔部24与隔挡板21一体成型,钉仓保护盖2安装到钉仓本体1的上面后,阻隔部24与钉仓本体1的顶端面14抵靠,这样,阻隔部24在所述隔挡板21与所述钉仓本体1之间形成空间,有效地将隔挡板21与钉仓本体1隔离。避免了在存储、运输或装配过程中,由于钉尖是锐利的,钉尖受挤压或晃动等原因接触隔挡面211后略嵌入隔挡面211的情形,避免了取下钉仓保护盖2时,钉仓保护盖2连同部分缝合钉3一起脱离钉仓本体1的情况。
阻隔部24、第一卡钩部22、第二卡钩部23及所述隔挡板21一体成型形成钉仓保护盖2。隔挡板21的隔挡面211上交错排列布置阻隔部24、第一卡钩部22、第二卡钩部23,也就是说,在隔挡板21的长度方向上,阻隔部24、第一卡钩部22、第二卡钩部23不重叠,便于加工成型及脱模。
隔挡板211上设有凸起,所述凸起形成阻隔部24;阻隔部24为柱体或细长的长方体。根据本发明的一个实施例,如图9所示,阻隔部24为长方体或柱体;在本实施例中,阻隔部24为条状体;或者在本发明的另两个实施例中,如图10或图11所示,阻隔部24为散点状凸起,所述凸起呈柱状,阻隔部24的横截面为圆形、椭圆形或多边形,优选地,阻隔部24的横截面为圆形或正多边形。阻隔部24与钉仓本体1顶端面14的实心位置(除钉腔12以外的位置)接触,这样,阻隔部24在所述隔挡板21与所述钉仓本体1之间形成空间,以保证所有的针尖3与钉仓保护盖2都不接触。当需要取下钉仓保护盖2时,因所有的针尖3与钉仓保护盖2都不接触,有效避免了钉仓保护盖2连同部分缝合钉3一起脱离钉仓本体1的情况。
在本发明的第四个实施例中,阻隔部17位于钉仓本体1上(在此实施例中,钉仓保护盖2上不设置阻隔部)。具体地,所述阻隔部17位于钉仓本体1的上表面上并且沿钉仓本体1的上表面的中心轴线对称设置。阻隔部17的高度小于所述缝合钉3的高度,能在缝合钉3未被击发时,很好地将其封堵在钉仓本体1内;优选地,阻隔部17的高度为0<h≤1mm,而吻合钉的高度为1.5≤H≤10mm,进一步地,吻合钉的高度为2≤H≤6mm。阻隔部17与钉仓本体1一体成型,钉仓保护盖2安装到钉仓本体1的上面后,阻隔部17与隔挡板21的隔挡面211抵靠,这样,阻隔部17在所述隔挡板21与所述钉仓本体1之间形成空间,有效地将隔挡板21与钉仓本体1隔离。避免了在存储、运输或装配过程中,由于钉尖是锐利的,钉尖受挤压或晃动等原因接触隔挡面211后略嵌入隔挡面211的情形,避免了取下钉仓保护盖2时,钉仓保护盖2连同部分缝合钉3一起脱离钉仓本体1的情况。
第一卡钩部22、第二卡钩部23及所述隔挡板21一体成型形成钉仓保护盖2。隔挡板21的隔挡面211上交错排列布置第一卡钩部22、第二卡钩部23,也就是说,在隔挡板21的长度方向上,第一卡钩部22、第二卡钩部23不重叠,便于加工成型及脱模。
如图12所示,钉仓本体1上设有凸起,所述凸起形成阻隔部17;阻隔部17为柱体或细长的长方体。阻隔部17为散点状凸起,所述凸起呈柱状;阻隔部17的横截面为圆形、椭圆形或多边形,优选地,阻隔部17的横截面为圆形或正多边形。或者,阻隔部17为长方体;具体地,阻隔部17为连续的条状体。在存储、运输过程中,钉仓保护盖2可拆卸地连接在钉仓本体1上,阻隔部17在所述隔挡板21与钉仓本体1之间形成空间,以保证所有的针尖3与钉仓保护盖2都不接触。当需要取下钉仓保护盖2时,因所有的针尖3与钉仓保护盖2都不接触,有效避免了钉仓保护盖2连同部分缝合钉3一起脱离钉仓本体1的情况。
在本发明的第五个实施例中,如图13所示,钉仓本体1和钉仓保护盖2上均设置阻隔部。具体地,钉仓本体1上设有阻隔部17,钉仓保护盖2上设置阻隔部24。阻隔部17位于钉仓本体1的上表面上并且沿钉仓本体1的上表面的中心轴线对称设置,阻隔部24沿所述隔挡板21的中心轴线对称设置。阻隔部17、阻隔部24的高度相等,且均小于所述缝合钉3的高度,能在缝合钉3未被击发时,很好地将其封堵在钉仓本体1内;优选地,阻隔部17、阻隔部24的高度均为0<h≤1mm,而吻合钉的高度为1.5≤H≤10mm,进一步地,吻合钉的高度为2≤H≤6mm。阻隔部17与钉仓本体1一体成型,钉仓保护盖2安装到钉仓本体1的上面后,阻隔部17与阻隔部24不重叠;阻隔部17与阻隔部24共同在隔挡板21与所述钉仓本体1之间形成空间,有效地将隔挡板21与钉仓本体1隔离。避免了在存储、运输或装配过程中,由于钉尖是锐利的,钉尖受挤压或晃动等原因接触隔挡面211后略嵌入隔挡面211的情形,避免了取下钉仓保护盖2时,钉仓保护盖2连同部分缝合钉3一起脱离钉仓本体1的情况。
钉仓保护盖2还包括定位脊25,所述定位脊25为沿所述钉仓保护盖2的对称轴向下延伸形成,且垂直于隔挡板21,定位脊25插入钉仓本体1的推钉槽13内,定位脊25的高度大致等于推钉槽13的槽深,进一步地,定位脊25的两侧还设有加强筋251,当定位脊25插入钉仓本体1的推钉槽13内时,所述加强筋251与推钉槽13的两侧接触。一方面,起到将钉仓保护盖2与钉仓本体1预定位的作用,便于准确、快速地将钉仓保护盖2装配到钉仓本体1上;另一方面,加强筋251与推钉槽13的两侧接触可以增强钉仓保护盖2与钉仓本体1的固定效果,防止钉仓保护盖2脱离钉仓本体1,且加强筋251与推钉槽13的两侧接触面积小,也便于使用时取下钉仓保护盖2。推钉槽13、推钉块5和支撑件6是现有技术,在此不再赘述。
根据本发明的外科器械1000,既能在缝合钉3未被击发时很好地将其封堵在钉仓本体1内,避免了缝合钉3在存储、运输过程中因挤压或受外力而脱离钉仓本体1的情况;同时又解决了钉仓组件100在装配到外科器械的端部执行器内、取下所述钉仓保护盖2时,部分缝合钉3被钉仓保护盖2带起从而一起脱离钉仓本体1的问题。根据本发明的钉仓组件及其外科器械结构紧凑可靠、装配方便,可有效缝合患者的伤口、从而减少伤口出血,有利于手术的顺利进行及术后患者伤口的愈合。
