Description
技术领域
本发明涉及主要用于医疗用途的球囊导管、及其制造装置和制造方法。
背景技术
球囊导管通过在中空的柔软的管(以下称为管子)的前端部等设有能膨胀及收缩的气球(以下称为球囊)来构成。
该球囊导管主要用于医疗用途。例如,作为使用该球囊导管的治疗方法,有经皮冠状动脉成形术(PTCA:percutaneous transluminal coronaryangioplasty)等。该治疗方法通过将称为导丝(guide wire)的较细的金属丝穿过变窄的病变部,将球囊沿着该金属丝送到病变部,使球囊鼓起以扩大病变部。
如上,球囊导管是插入血管内等人或动物的体内的导管,需要是光滑的形状以不损伤体内。
一般而言,在球囊导管的制造中,对于由中央的直径较粗的主体部和主体部两端的直径较细的端部所构成的筒状的球囊,通过将导管管子插入球囊的两个端部内,利用热将该球囊的两端部与导管管子进行熔接或利用粘接剂来进行粘接等来进行制造。
例如,已知有通过将激光照射到导管端部来进行熔接的球囊导管的制造方法(参照专利文献1)。在该专利文献1中,利用透镜对远红外线范围的激光进行聚焦,将由透镜聚焦后的远红外线范围的激光对导管管子(导管)与球囊(扩张球囊)的末端端部的边界部分进行照射来进行熔接。

发明内容
发明所要解决的技术问题
在上述专利文献1中公开的技术中,将激光聚焦在导管管子与球囊的边界部分,将它们同时进行加热,但是,一般而言,球囊比导管管子要薄,随着对边界部分进行加热,球囊先发生熔融而使球囊破损。此外,作为激光,远红外线范围的激光输出功率较大,难以进行调节。因此,在专利文献1中,熔接时,提高使球囊导管旋转的转速,但存在难以细微地调节熔接程度的问题。
此外,在上述专利文献1中,使用热收缩管子(热缩管)来对球囊和导管管子进行加压的,但是,一般而言,热收缩管子受使用环境的温度影响而难以进行处理。而且,由于发生收缩变形,因此,热收缩管子有时会产生加压位置偏差、收缩不均等,在熔接之后的表面形状上出现凹凸或高低差。此外,还存在难以拆卸熔接之后的热收缩管子的问题。
如上所述,在使用远红外线范围的激光和收缩管子聚焦在导管管子与球囊的边界部分来进行熔接的方法中,不易将熔接部分精加工成所希望的形状。而且,如果球囊导管存在凹凸等,则存在难以用于医疗用途的问题。
本发明是为了解决如上所述的技术问题而实施的,其目的在于提供一种球囊导管及其制造装置和制造方法,能细微和恰当地调节熔接程度,不必使用难以处理的热收缩管子,能进行在熔接之后的表面形状上没有凹凸和高低差的熔接,成为与用途相适应的所希望的表面形状,能良好地用于医疗用途。

具体实施方式
(实施方式1)
以下,参照附图说明本发明的实施方式。
参照图1,其表示本发明的实施方式1所涉及的球囊导管制造装置的外观立体图。
如图1所示,球囊导管制造装置1的外观由掩盖进行熔接操作的部分的盖板部2、显示有关熔接的信息的监视器部4、进行有关熔接的各种设定等的熔接操作部6所构成。
盖板部2可以开闭,在关闭时的盖板部2内部进行熔接操作。图2表示将该盖板部2打开时的球囊导管制造装置1的外观立体图。另外,图2中进行了简化表示,以便理解握持未图示的轴14(发热轴)并使该轴14以规定转速旋转的卡盘16(发热轴旋转单元)、激光照射单元8、照相机12之间的位置关系。在熔接操作时,该盖板部2防止垃圾或操作人员的手等的进入,并可兼用于屏蔽激光,从而确保熔接操作的安全性。
监视器部4是触摸屏,除了利用熔接操作部6能操作的事项以外,还能根据该监视器部4的画面上的显示进行操作。
在熔接操作部6设有球囊导管制造装置1的电源按钮、激光照射开始位置(熔接开始位置)或激光照射结束位置(熔接结束位置)的调节/登记按钮、手动操作按钮、紧急停止按钮、及熔接开始按钮等。
接下来,对球囊导管制造装置1的内部结构进行说明。
参照图3,其表示本发明所涉及的球囊导管制造装置的示意内部结构图。
如图3所示,球囊导管制造装置1的内部由对熔接对象照射激光的激光照射单元8、将该激光照射单元8支承成能移动的激光支承单元10、对激光照射位置进行拍摄的照相机12、在单一方向上延伸的轴14(发热轴)、在对轴14的一端进行支承的同时能使其旋转的卡盘16(发热轴旋转单元)、以及将轴14的另一端侧支承成能自由旋转的3个轴引导件18、20、22所构成。另外,对于轴引导件,从靠近卡盘16的一侧起依次称为前轴引导件18、中央轴引导件20、后轴引导件22,中央轴引导件20及后轴引导件22如上述图1所示那样设置在监视器部4的下部。上述中央轴引导件20及后轴引导件22以外的轴引导件设置在盖板部2的内侧。
此外,上述监视器部4、熔接操作部6、激光照射单元8、激光支承单元10、照相机12等各种设备与熔接控制部24进行电连接。
对上述各种设备进行详细说明,激光照射单元8例如是半导体激光器,其指向下方,以对处于被卡盘16固定的状态的轴14照射激光。由该激光照射单元8照射出的激光聚焦于轴14附近的规定的点且呈圆锥状来进行照射。此外,该激光的波长为700nm~1200nm的范围,优选为800nm~1000nm。
激光支承单元10的臂部10a与激光照射单元8连结,形成为能使激光照射单元8和该臂部10a一起在与轴14正交的上下方向(Z轴方向)及与轴14相同方向的水平方向(X轴方向)上进行移动。
照相机12例如是CCD照相机,对激光照射位置的状况进行动画拍摄。该照相机12被支承成与激光支承单元10在X轴方向上的移动连动,构成为即使激光照射单元8在X轴方向上发生移动的情况下也能持续拍摄激光照射位置。
轴14是受到由上述激光照射单元8照射出的激光而发热的轴,例如,是不锈钢丝。
卡盘16对该轴14的一端进行支承以使轴14在X轴上延伸,并使该轴14以该轴14的轴心为中心进行旋转。
前轴引导件18、中央轴引导件20、后轴引导件22分别将轴14的另一端侧支承成能自由旋转。
熔接控制部24中输入有来自与其电连接的上述各种设备的信息,并根据该信息对各种设备进行控制。例如,熔接控制部24将由照相机12拍摄到的影像显示在监视器部4上。此外,熔接控制部24根据对熔接操作部6和监视器部4进行的操作来控制相对应的设备的动作。具体而言,作为对激光照射单元8的控制,调节激光的输出,并使激光照射单元8相对于激光支承单元10分别在X轴方向上进行移动来调节激光照射位置,在Z轴方向上进行移动来调节激光照射面积。此外,熔接控制部24通过调节卡盘16的转速来调节激光照射到熔接对象的时间。
上述激光的输出调节、激光照射单元8在Z轴方向及X轴方向的移动、卡盘16的转速等各种参数由操作人员预先进行设定,例如,也可以根据熔接的进展情况可变地设定激光输出。
接下来对作为熔接对象的球囊导管进行说明。
图4是表示设置在球囊导管制造装置上的球囊导管的示意图。
如图4所示,球囊导管26由能从收缩或折叠的状态膨胀的球囊28、插入该球囊28的两端部28b、28c内的管状的导管管子30a、30b所构成。
详细而言,球囊28在膨胀时呈大直径的圆筒状的主体部28a的两端侧朝着轴心呈锥状地缩小,双方的端部28b、28c呈小直径的圆筒状。该球囊28由具有柔软性且使从上述激光照射单元8照射出的激光透过的透明树脂原材料、例如聚酯、聚烯烃、聚酰胺、热塑性聚氨酯所构成。
导管管子30a、30b是外径与球囊端部28b、28c的内径基本相同、且内径与上述轴14的直径基本相同的管构件。而且,该导管管子30a、30b由具有柔软性且使激光透过的树脂原材料所构成。此外,该导管管子30a、30b的厚度比上述球囊28的厚度要厚。另外,球囊28及导管管子30a、30b只要是使激光透过的原材料即可,导管管子30a、30b也可以是吸收激光而发热的情况。此外,颜色并不限于透明。例如,可以是稍许着色为黑色等的原材料,即使在受到激光照射时球囊28本身或导管管子30a、30b本身或多或少发热,只要使激光透射到导管管子30a、30b的内侧即可。
然后,将导管管子30a、30b插入球囊端部28b、28c中,将该球囊端部28b、28c与导管管子30a、30b重合的部分设为熔接对象部分。
在利用上述球囊导管制造装置1将该熔接对象部分进行熔接时,将上述轴14穿过作为熔接对象部分内侧的导管管子30a、30b内,加压管子32a、32b与熔接对象部分外侧即球囊端部28b、28c的外侧和导管管子30a、30b的一部分进行嵌合。
该加压管子32a、32b由使激光透过且具有弹性的原材料、例如硅酮(硅酮橡胶)所构成。此外,该加压管子32a、32b呈环状,其内径比球囊端部28b、28c的外径稍小,通过使该加压管子32a、32b与球囊端部28b、28c嵌合,利用其弹力将该球囊端部28b、28c及导管管子32a、32b朝位于轴心的轴14进行加压。此外,加压管子32a、32b与球囊端部28b、28c和导管管子30a、30b的一部分嵌合,以至少覆盖熔接对象部分,因球囊端部28b、28c与导管管子30a、30b之间的高低差而产生微小的间隙。
由此,在安装了轴14及加压管子32a、32b的状态下,将球囊导管26设置在上述球囊导管制造装置1上。此时,将球囊28配置成位于卡盘16和前轴引导件18之间,轴14的一端由卡盘16握持,轴14的另一端侧由各轴引导件18、20、22支承。
以下,对设置了熔接之前的球囊导管26的球囊导管制造装置1进行的熔接方法进行说明。图5是表示从作为激光光源的激光照射单元8到达激光照射区域为止的距离与激光照射区域的大小的关系的示意图。来自激光照射单元8的激光呈倒圆锥状地缩小来进行照射。因此,熔接对象部分在靠近激光照射单元8的位置激光照射区域较大,越是远离激光照射单元8则激光照射区域越小。由图5可以理解为,自激光照射单元8的距离为Z0时,激光照射区域较大(A0),随着离开激光照射单元8(Z1、Z2),激光照射区域变小(A1、A2)。
图6A、图6B是表示熔接前后的球囊导管的熔接对象部分的剖视图,在上述图4、图5的基础上,根据该图6A、图6B来说明熔接方法。
如图4所示,本实施方式中,对球囊28的一端侧的端部28b进行熔接,然后,对另一端侧的端部28c进行熔接。
首先,设定球囊28的一端侧及另一端侧的熔接开始位置。操作人员通过显示在监视器部4上的照相机影像一边确认球囊导管26的位置一边操作熔接操作部6,从而确定恰当的熔接开始位置。本实施方式中,将球囊28的一端侧及另一端侧的端部28b、28c的末端位置设为各熔接开始位置,并登记到存储部(存储单元)25中。另外,激光照射开始于熔接开始位置,因此,熔接开始位置就是激光照射开始位置。同样,在熔接结束位置使激光照射结束,因此,熔接结束位置就是激光照射结束位置。
在确定了熔接开始位置之后,设定在球囊28的一端侧及另一端侧的、激光照射单元8沿Z轴方向的位置及激光输出。此处,激光输出可以根据熔接的进展状况进行改变,例如,本实施方式中,将激光输出设定成随着熔接的进行而逐渐下降。对于激光照射单元8沿着该Z轴方向的位置,作为熔接参数之一存储到存储部25中。
这样,将有关熔接的条件进行设定,然后,在盖板部2关闭的状态下按压熔接操作部6的熔接开始按钮,通过熔接控制部24对各种设备进行控制,从而开始与设定相应的熔接操作。
如图6A所示,在该熔接操作中,根据所设定的条件,卡盘16使轴14进行旋转,从而使该轴14、导管管子30a、30b、球囊28、及加压管子32a、32b一体地进行旋转。另外,在图6A、图6B和其他各图中,为了方便说明,将球囊28、导管管子30a的厚度记载得比现实的厚度要厚,例如,图6A中,记载了球囊端部28b末端与导管管子30a之间存在高低差,但现实中该高低差极小。
接下来,由激光照射单元8照射激光,该照射出的激光透过加压管子32a、球囊端部28b、导管管子30a而照射到轴14上。轴14受到该激光的照射而发热。然后,导管管子30a受到来自该轴14的发热部B的热而被加热,球囊端部28b从该被加热后的导管管子30a接受热而被加热。
在图6B中,在熔接之后的球囊导管的熔接对象部分的剖视图中,画上较细的阴影(斜线)来表示熔融部C。从内侧加热导管管子30a及球囊端部28b使它们达到熔点,从而使其熔融。加压管子32a朝轴心方向对导管管子30a及球囊端部28b加压,因此,若发生熔融而产生流动性,则球囊端部28b从导管管子30a的表面向内侧熔化而进行熔合,以流向加压管子32a与导管管子30a之间的球囊端部28b的前端侧(图6A的D部分)。
使用图7A、图7B对此进行稍许详细的说明。加压管子32a对仅有导管管子30a的部分、以及在导管管子30a的外侧重叠有球囊端部28b的部分均进行加压。因此,加热之前如图7A那样,由于仅有导管管子30a的部分与在导管管子30a上重叠有球囊端部28b的部分的厚度不同,因此,如图7A的白色箭头的大小的差异所示那样,以存在高低差的E点为界产生压力差。若导管管子30a及球囊端部28b被加热到发生熔融而出现流动性,则如图7B那样,没有了维持高低差的力,因此高低差消失,球囊端部28b与导管管子30a的接合点变为没有高低差或凹凸的、由光滑的曲面相连的形状。
然后,若激光照射单元8按照预先设定的时间及预先设定的激光输出变化来照射激光,则结束一端侧的熔接操作。接下来,移动到另一端侧的熔接开始位置,与一端侧同样地进行与设定相应的熔接操作。
在结束了球囊28的一端侧及另一端侧的熔接操作之后,从卡盘16拆卸轴14,拆卸加压管子32a、32b及轴14,从而完成球囊导管26。
由此,将球囊端部28b、28c与导管管子30a、30b进行了熔接的球囊导管28如图6B所示那样,球囊端部28b的末端的外径与导管管子30a的外径一致而成为一体,呈从此处向主体侧光滑地扩大的形状。
如上所述,在上述球囊导管制造装置1及制造方法中,激光透过球囊28及导管管子30a、30b而使轴14发热,从导管管子30a、30b的内侧进行加热,从而能抑制对与导管管子30a、30b相比厚度较薄的球囊28过度的加热,能在防止球囊28发生破损等的情况下进行熔接。
此外,一边从导管管子30a、30b的内侧进行加热,一边利用弹性构件的加压管子32a、32b朝轴心方向进行加压,从而以使球囊28朝导管管子30a、30b内熔化的方式进行熔接。该加压管子32a、32b不是利用热收缩等进行加压,而是利用其弹力进行加压,因此,不会产生加压位置的偏差、熔接之后加压管子32a、32b不易脱开等问题,对熔接对象部分均等地加压,从而能在熔接之后的表面形状不会产生凹凸的情况下进行熔接。
图6A中,将激光照射单元8沿着Z轴方向固定在靠近轴14的位置上,激光照射在较大的激光照射区域。尽管对激光照射单元8进行了固定,但由于使轴14在由卡盘16握持的状态下进行旋转,因此,在轴14的外周表面上,激光照射区域的中心位置最为发热,周边部的发热程度降低。此外,处于激光照射区域的中心位置的球囊28的端部28b、28c被加压管子32a加压,因此,以埋没在导管管子30a内的形态进行熔融。由此,能将球囊28的端部28b与导管管子30a的表面没有凹凸地、光滑地进行熔接。
此外,在结束了球囊28的一端侧的熔接之后,能直接进行另一端侧的熔接,提高球囊导管26的生产效率。
(实施方式2)
在上述实施方式1中,将激光照射单元8相对于X轴方向的位置进行了固定,因此,越是远离激光照射区域中心的周边部,轴14的发热程度越是下降,球囊端部28b的熔化程度也下降。因此,以往球囊端部28b的熔化局限于激光照射区域的中心部分。本发明的实施方式2中,通过使激光照射单元8沿着X轴及Z轴移动,使激光的输出可变,能在与熔接对象相对应的条件下进行熔接。
图8A中,将激光照射单元8沿着Z轴固定在比上述实施方式1稍许远离轴14的位置上,使激光缩小,将激光照射区域缩小来进行照射,并使激光照射单元8沿X轴移动,且使激光输出下降。随着激光照射区域的移动,发热部B沿着X轴移动,球囊28与导管管子30a的熔融部C也沿着X轴移动。此外,随着该移动,使激光输出逐渐下降。由此,熔融部C在X轴方向上扩大,对比图6B和图8B可见,球囊端部28b以在较宽的范围埋没在导管管子30a内的方式进行熔融,从而以没有凹凸的、光滑的形态一体化。
由此,能成为与用途相适应的所希望的表面形状,制造出能良好地用于医疗用途的球囊导管26。
图9是表示球囊导管的激光光源的激光照射开始位置、激光照射结束位置的、熔接对象物即球囊和导管管子的剖视图。图9中表示了以下四个位置的位置关系,这四个位置是:作为激光光源的激光照射单元8开始照射激光的激光照射开始位置(X1―1);结束激光照射的激光照射结束位置(X2―1);从激光照射开始位置(X1―1)离开移动距离(L)的、另一端侧的端部的激光照射开始位置(X1―2);以及结束激光照射的激光照射结束位置(X2―2)。
尤其是本实施方式那样,在球囊28的末端侧使激光的输出增大,朝球囊28的中央即主体侧使激光的输出降低,以此方式进行熔接,随着接近主体侧,轴14的发热程度下降,球囊端部28b、28c的熔化程度也下降,球囊28的端部末端的外径与导管管子30a、30b的外径相一致而构成一体,能成为从此处到主体侧光滑地扩大的形状的球囊导管26。
由此,将激光照射开始位置以及激光照射结束位置登记在作为存储单元的存储部25中,在熔接时,通过作为登记读取这些位置的登记读取单元发挥作用的熔接控制部24从存储部25读取激光照射开始位置以及激光照射结束位置,使用激光支承单元使激光从激光照射开始位置照射到激光照射结束位置,从而对球囊28的端部与导管管子30a、30b重叠的熔接对象部分进行熔接。
另外,也可以在图9所示的激光照射开始位置(X1―1)到激光照射结束位置(X2―1)之间确定规定位置(Xm―1)、(Xn―1),预先将各个规定位置处的激光照射条件等熔接条件登记到存储部25中,登记之后,在熔接控制部24从存储部25读取的熔接条件下对熔接对象部分进行熔接。对此,在后面使用图15、图16进行详细说明。
图10是表示存储在存储部25中的球囊导管的熔接条件的数据结构的图。图10中,作为熔接条件的熔接参数,例如,例示有以下项目:(1)激光的激光照射区域(激光光点)的直径;(2)轴14的转速;(3)激光照射单元8是固定还是可移动;(4)激光照射开始位置;(5)激光照射结束位置;(6)激光照射单元8的移动速度;(7)对球囊28的单侧还是两侧进行熔接;(8)如果是对球囊28的两侧进行熔接,则使激光照射单元8移动的距离;(9)球囊28和导管管子30a、30b的材质;(10)球囊28和导管管子30a、30b的厚度。在存储部25中,将输入了上述一系列的项目值的数据作为一个熔接条件而存储多个熔接条件。
此外,对于图10的各熔接条件,将对实际熔接的结果作出了评价的评价得分进行存储。由此,为了制作出所希望的球囊导管26,改变熔接参数并进行实际熔接,进行评价,将其评价结果与各熔接条件相关联,按照评价得分高的顺序将熔接条件进行排序并显示,从而容易找到最佳的熔接条件。此外,例如,若利用实验规划法,改变各熔接参数并进行实际熔接以输入评价结果,则容易找到用于得到所希望的球囊导管26的最佳候选熔接条件。
图11是表示将熔接条件登记到存储部25中的动作步骤的流程图。沿着流程图的步骤对登记熔接条件的动作进行说明,首先,输入球囊28和导管管子30a、30b的材质、厚度等条件(步骤S1)。
接下来,输入激光光点直径(步骤S2)。输入轴14的转速(步骤S3)。然后,输入将激光照射单元8保持固定还是使其移动(步骤S4)。在使激光照射单元8移动的情况下,输入激光照射开始位置(步骤S5)。输入激光照射结束位置(步骤S6)。输入激光照射单元8的移动速度(步骤S7)。另外,在将激光照射单元8保持固定的情况下,不进行步骤S5、S6、S7的动作。
接下来,输入所需熔接的是球囊28单侧的端部还是两侧的端部(步骤S8)。在对球囊28的两侧的端部28b、28c进行熔接的情况下,输入移动激光照射单元8的距离(步骤S9)。然后,输入另一端侧的激光照射开始位置(步骤S5),输入激光照射结束位置(步骤S6),输入移动速度(步骤S7)。如果完成了对球囊28的单侧或两侧的端部的输入,则设定激光输出是可变还是不可变。在使激光输出可变的情况下,输入如何使其可变的熔接条件(步骤S10)。然后,进行实际熔接(步骤S11),输入熔接评价结果(步骤S12)。将以上的输入信息作为一个熔接条件登记到存储部25中(步骤S13)。
图12是表示读取存储部25中所登记的熔接条件来进行熔接动作的步骤的流程图。输入有关所希望的球囊28和导管管子30a、30b的材料的材质、厚度等熔接的规格条件(步骤S21)。于是,将与所输入的规格条件相同或类似的、对球囊导管进行了实际熔接的熔接条件按照评价高的顺序显示在监视器部4上(步骤S22)。若从其中任意选择熔接条件(步骤S23),则能在该选择的条件下进行熔接操作(步骤S24)。如果想要获取进一步的熔接条件,则能任意改变熔接参数中的任一项,并进行改写而登记到存储部25中,在新的熔接条件下进行熔接。如果出现比以往要好的熔接结果,则可获得更好的熔接条件。
根据本发明的球囊导管制造装置,不仅将各熔接参数作为一套熔接条件来存储多个熔接条件,而且还输入并存储实际进行了熔接的评价结果,因此,通过选择出现高评价的熔接条件,能进行稳定、高质量的熔接操作。可以说,将熔接条件和评价结果教给(施教于)球囊导管制造装置,若输入有关所希望的球囊和导管管子的材料的材质、厚度等熔接的规格条件,则对于该条件能将评价结果较高的熔接条件作为候选熔接条件进行监视器显示,因此,具有能从完成评价的候选熔接条件中迅速选择出所希望的熔接条件这样的优点。
另外,尽管在图10的熔接参数的项目中未曾提及,但本发明中,如已经说明的那样,能使激光照射单元的激光输出可变。图13和图14中示出了使激光输出从熔接开始位置到熔接结束位置为止阶梯式变化的示例。在图13所示的示例中,将从熔接开始位置即激光照射开始位置(X1―1)到熔接结束位置即激光照射结束位置(X2―1)之间一分为五,使激光输出分5个台阶依次减小。图14所示的示例中,将从激光照射开始位置(X1―1)到激光照射结束位置(X2―1)之间同样一分为五,使激光输出在最初的2/5的位置为止维持最大输出功率,然后,阶梯式地减小。
如图13和图14所示,在熔接开始位置输出最大的激光输出,之后阶梯式地减小,在这样的情况下,能将球囊的最端部(端面附近)以埋没在导管管子中的方式进行熔接,此后,能减少球囊的端部埋没在导管管子中的量,因此,熔接后的球囊与导管管子的表面能由没有凹凸的、光滑的曲面相连。
由此,本发明中,通过预先将激光照射开始位置与激光照射结束位置之间的规定位置和规定位置处的熔接条件登记到存储单元(存储部25)中,从而在登记之后,熔接控制单元(熔接控制部24)从存储单元读取熔接条件,在所读取的熔接条件下对熔接对象部分进行熔接。
另外,上述说明中表示了将从激光照射开始位置(X1―1)到激光照射结束位置(X2―1)之间一分为五的示例,但也可以选择一分为三、一分为二这样的任意的分割数。此外,除了将激光输出阶梯式地进行改变以外,也可以设定成以连续的方式或模拟的方式改变为任意的值。例如,如图15那样,也可以在熔接开始位置即激光照射开始位置(X1―1)和熔接结束位置即激光照射结束位置(X2―1)之间预先确定多个规定位置(Xm―1、Xn―1)和在各规定位置处的熔接条件,使激光输出与激光照射部8所移动到的规定位置相对应地连续且折线状地进行变化,如从图15的F点经过G点、H点、到I点。
图16用流程图表示图15那样设定熔接条件时的设定步骤。图16中,与前面说明的图11的步骤S1相同,输入球囊28和导管管子30a、30b的材质、厚度等条件,在步骤S30中,输入激光照射开始位置(X1―1)和在该位置处的熔接条件、例如激光输出(P5)。然后,在步骤S31中,输入规定位置(Xm―1)和在该位置处的熔接条件、例如激光输出(P4),在步骤S32中,输入规定位置(Xn―1)和在该位置处的熔接条件、例如激光输出(P2),在步骤S33中,输入激光照射结束位置(X2―1)和在该位置处的熔接条件、例如激光输出(P1)。由此,如图15所说明的那样,能使激光输出与激光照射单元的移动一起发生变化。对球囊导管的两侧设定同样的熔接条件时,在图16的步骤S9返回步骤S30,输入相反侧的熔接条件的步骤与图11所说明的步骤相同。另外,图16的步骤中,对与图11的步骤相同的步骤标注相同的步骤编号,并省略其说明。
由此,球囊导管26是在球囊端部28b、28c与导管管子30a、30b的接合点没有高低差或凹凸的、光滑的形状,在作为医疗用途而插入血管等体内时不会损伤体内,能安全地进行治疗。
以上是对本发明所涉及的球囊导管、球囊导管制造装置及制造方法的实施方式1、2进行的说明,但实施方式并不限于上述实施方式。
例如,图17中示出上述球囊导管26的变形例1。如图17所示,在变形例1的球囊导管40中,将直径各不相同的第一导管管子44、第二导管管子46分别插入球囊42的一端侧端部42a和另一端侧端部42b。
由此,在将直径各不相同的导管管子44、46分别熔接在球囊端部42a、42b上的情况下,使用具有与各导管管子44、46的内径相匹配地在中途直径发生变化的两个阶段的直径的轴48,使该轴48与各导管管子44、46的直径相匹配地插通。由此,即使在熔接直径各不相同的导管管子44、46的情况下,也能利用上述球囊导管制造装置1对球囊42的两个端部42a、42b持续地进行熔接,能起到与上述实施方式相同的效果。
此外,图18中示出上述球囊导管26的变形例2。如该图所示,球囊导管50通过使一根导管管子54贯通球囊52的两个端部52a、52b而构成。在该导管管子54的与球囊52的主体部52c相对应的位置上形成有能向球囊52内供给药剂等流体的多个孔54a。
即使是具有上述结构的球囊导管50,也能利用上述导管制造装置1与上述实施方式相同地对球囊端部52a、52b和导管管子54进行熔接,能起到与上述实施方式相同的效果。
另外,上述实施方式中,球囊导管是插入血管内的,但并不限于此,也可以是用于胸腔或腹腔等体腔、消化管或尿管等管腔部的球囊导管。
以上,在本发明的实施方式1、2中,对在中空的柔软导管管子的前端部熔接能膨胀和收缩的球囊的情况进行了说明,但本发明也能适用于将中空的柔软导管管子彼此进行连接的情况。
(实施方式3)
以下,对本发明的实施方式3进行说明。一般而言,导管管子(以下简称为导管)根据用途来使用粗细为1~10mm左右、长度从数cm到2m左右的各种导管。其中,还使用将较细的导管与较粗的导管进行连接、在中途改变粗细的导管。在对导管进行连接时,与球囊导管的情况相同,连接部分需要成为光滑的形状以不损伤体内。因此,根据本发明,能使导管的连接部分成为与用途相适应的所希望的表面形状,制造出能良好地用于医疗用途的导管。
图19A、图19B表示将较细的导管与较粗的导管这样的粗细不同的一对导管管子端进行重合、并照射激光进行熔接、以制造在中途粗细发生变化的导管时的熔接前后的熔接对象部分的剖视图。
在图19A中,将内径与该轴14的直径大致相同的较细的导管作为内侧管子60来被覆轴14,将内径与该内侧管子60的外形的直径基本相同且厚度较薄的较粗的导管作为外侧管子61来被覆在内侧管子60上,使加压管子32a与外侧管子61的端部和内侧管子60的一部分进行嵌合。然后,由激光照射单元8照射激光。如果关注熔接对象部分,则图19A可以理解为将已经说明的图6A的球囊28置换成一定粗细的外侧管子61。从激光照射单元8发射出的激光透过加压管子32a、外侧管子61、内侧管子60而照射到轴14上。轴14受到该激光照射而发热。然后,内侧管子60受到来自该轴14的发热部B的热而被加热,外侧管子61从该被加热的内侧管子60接受热而被加热。
在图19B中,在熔接对象部分的剖视图中画上较细的阴影(斜线)来表示熔融部C。从内侧对内侧管子60及外侧管子61进行加热而达到熔点,从而使其熔融。内侧管子60及外侧管子61被加压管子32a朝轴心方向加压,因此,若发生熔融而产生流动性,则熔化而进行熔合,以流向加压管子32a与外侧管子61之间的间隙部分(D部分)。然后,外侧管子61的末端的外径与内侧管子60的外径相一致而成为一体,呈从此处朝外侧管子61光滑地扩大的形状。
图20A、图20B中示出了以下的结构情况,即,将激光照射单元8沿着Z轴固定在比图19A稍许远离轴14的位置上,从而缩小激光、缩小激光照射区域以进行照射,并使激光照射单元8沿着X轴移动且降低激光输出。图20A的结构中,发热部B随着激光照射区域的移动而沿着X轴移动,外侧管子61和内侧管子60的熔融部C也沿着X轴进行移动。此外,使激光输出随激光照射区域的移动而下降。由此,熔融部C在X轴方向上扩大,将图20B与图19B对比可见,外侧管子61的端部以在较宽范围埋没在内侧管子60中的方式进行熔融。从而,以没有凹凸的光滑的形态一体化。
以上,本发明的实施方式3中,对将粗细不同的一对导管的端部进行重合而得到的重合部作为熔接对象部分、用激光对该熔接对象部分进行熔接连接的情况进行了说明。
(实施方式4)
本发明还适用于将一对导管的端面彼此对接来进行熔接连接的情况。以下,作为实施方式4进行说明。
图21A表示以下的状态,即,将粗细相等的一对导管各自的端面对接的状态下,用加压管子72从外周部进行加压,通过照射激光,对一对导管无高低差地进行熔接。激光透过加压管子72和一对导管(具体而言是左侧管子70和右侧管子72的端部)而使轴14发热,从而使左侧管子70和右侧管子71的端部熔融而连接成一体。图21B表示将粗细相等的一对导管进行熔接连接之后的状态。
另外,实施方式4中,使加压管子72的加压力比实施方式3的情况要小。实施方式4的加压管子的作用是在保持一对导管的对接部分的外径尺寸的情况下进行熔融、固化。在对一对导管的对接部分进行了熔融、固化的情况下,如果是表面光滑且稍许细小的程度,则不会损伤体内或血管内的通过性。根据需要,改变加压管子72的材质、厚度、或结构,预先使两端处的加压力较强,中央部的加压力较弱,从而在保持一对导管的对接部分的外径尺寸的情况下进行熔融、固化。
图21A、图21B中,轴14发热,轴14的热使一对导管的对接面附近发生熔融,但作为一对导管的原材料,也可以使用具有规定的激光吸收率的原材料,在使轴14发热的同时,使一对导管本身也同时发热,从而使其熔融来进行连接。
图22A表示以下的状态,即,将粗细不同的一对导管各自的端面对接的状态下,用加压管子73从外周部进行加压,通过照射激光,对一对导管无高低差地进行熔接。图22A中,使内径相等但外径较小、粗细较细的左侧管子80的端面与右侧管子71的端面对接,使加压管子73与具有高低差的对接部分嵌合来进行加压,因此,对接部分的熔融部C如图22B那样固化成圆锥状。
另外,尽管未图示,但也可以如实施方式2那样,进一步设置对一对导管的端面的对接部分进行拍摄的照相机单元、将由照相机单元拍摄到的图像进行显示的监视器单元、存储单元、在存储单元中登记、读取激光照射开始位置及激光照射结束位置的登记读取单元、以及将激光照射单元支承成能移动的激光支承单元,在将由照相机单元拍摄到的图像在监视器单元上进行显示时,将激光照射开始位置及激光照射结束位置登记到存储单元中,在熔接时,从存储单元读取激光照射开始位置及激光照射结束位置,在使用激光支承单元使激光从激光照射开始位置照射到激光照射结束位置时,改变对直径较粗的导管照射激光时的激光输出、及对直径较细的导管照射激光时的激光输出,在与导管的粗细相对应的熔接条件下进行熔接。由此,能将粗细不同的一对导管的端面更光滑地进行连接。
此外,作为图21A、图21B、图22A、图22B所示的实施方式4的变形例,也可以如图23A、图23B、图24A、图24B那样,将一对导管的端面设为在轴向上倾斜的圆锥面J,一个管子的圆锥状的端面被另一个管子的端面覆盖。如果一个管子的圆锥状的端面被另一个管子的端面覆盖,则对接部分的抵接面积扩大,能以更宽的抵接面使一对导管熔融而成为一体,能更可靠地进行连接。这不仅适用于图23A、图23B那样粗细相等的一对导管各自的端面以圆锥状对接的情况,而且适用于图24A、图24B那样粗细不同的一对导管各自的端面以圆锥状对接的情况。
在将粗细不同的一对导管进行熔接时,使激光照射单元8在轴方向上移动,并改变对直径较粗的导管照射激光时的激光输出、和对直径较细的导管照射激光时的激光输出,能在与直径粗细相对应的熔接条件下进行熔接,这与前面的说明相同。
此外,也可以如图25所示,将一个导管91的端面设为圆锥状,但将另一个导管95的端部设为与轴向成直角地切断的形状,并以爬上一个导管91的圆锥面上的方式进行重合,使加压单元96与重合部分嵌合,从加压单元96的外侧对轴14的表面照射激光而使轴14发热,从而对重合部分进行熔接。图25的情况具有以下优点,即,只要对一个导管91实施使端面成为圆锥状这样的特殊加工即可。
