Description
本申请是2003年9月29日提交的、发明名称为“用于牙科的数字传感器的支架”、申请号为03134754.1的发明专利申请的分案申请。
技术领域
本发明涉及一种用于牙科的数字传感器的支架。
背景技术
直到最近,X光照片还是被记录在X射线胶片上的,所述X射线胶片被爆光,随后被冲洗出来。由于这种X射线胶片是确定的标准规格,所以对应于各自夹紧部的支架的尺寸也是标准化的,所述夹紧部专门用来容纳所述X射线胶片。至今为止,当所述胶片的规格主要是被横向地或者纵向地夹紧时,关于这种X射线胶片支架,主要的问题是允许咬翼片和牙齿的其它区域的X光照片具有最小数目的不同的支架。
最近,研制出了一种新的成象技术,为了直接显示或者将X光照片存储在计算机中,该技术中的数字图象传感器可被直接地通过一电缆连接到一计算机上。
关于长度,宽度和厚度,和X射线胶片不太相同的是不同的数字传感器产品具有不同的尺寸。而且,这种类型的传感器包括一电缆,由此使得这种传感器的正确定位出现问题。例如,根据专利文件US-A-6,203,195,许多传感器支架都已经是公知的,该专利文件揭示了一传感器支架,所述传感器支架的支架臂是可伸展的以允许不同形式的保持。尽管这里已经建议使用不同的形式,但是这种支架的普遍应用受它的构造的限制。
文件WO/49945揭示了另一种传感器支架,一支架臂在该传感器支架中是可伸展的以缚住不同尺寸的传感器。所述构造在这里也不允许过分多样的传感器的普遍应用。
发明内容
在这种现有技术的背景下,本发明的目的是提供一组传感器支架,当一方面要提供一个好的定位,且另一方面要为患者提供最大程度的舒适度的时候,该传感器支架在前牙区和侧牙区,即,在根尖周组织中允许具有所有的有用的数字传感器的X光照片,以及水平的和垂直的咬翼片图象的存在。
本发明提供了一种用于牙科的数字传感器的支架,其特征在于:对于根尖周的X光照片和侧牙及前牙的X光照片,所述支架能够用于不同的传感器规格,传感器夹紧部包括用于将所述传感器压在独立于传感器规格的钳子上的夹紧爪,并且所述夹紧爪包括倾斜面,该倾斜面与导锁部分的倾斜面相互作用,使得所述夹紧爪能够通过在一个方向上移动所述导锁部分而被升高。
附图说明
通过在下文中参考例证实施例的附图,将对本发明进行更详细的解释。
图1所示为一支架的夹紧部的第一例证实施例的视图,其中该支架专门用于支撑根尖周的X光照片。
图2所示为图1中所示夹紧部的部件详细视图。
图3所示为具有一垂直设置的传感器的图1中所示的夹紧部的视图。
图4所示为一支架的夹紧部的第二例证实施例的视图,其中该支架专门用于支撑没有遮盖物的咬翼片图象。
图5所示为从对面看图4中所示夹紧部的视图。
图6所示为一支架的夹紧部的另一个例证实施例的部分剖视图,其中该支架专门用于支撑根尖周的图象。
图7所示为图6中所示夹紧部的侧视图。和
图8所示为图6中的部件详细视图。
具体实施方式
图1至图3所示为一支架的传感器夹紧部的第一例证实施例,在该支架的传感器夹紧部上,具有固定条的两个臂可以自动找正的方式移动。支架2的传感器夹紧部1包括两个臂3,3A,这两个臂被铰接在各自的轴4,4A上,并且这两个臂包括各自的由一凸轮轴6以下述方式致动的角状杆5,5A,该方式是在图2中所述杆向下枢转,因此所述臂向内旋转。所述凸轮轴受一用于松开所述臂的联锁杆7的作用,由此,它们被旋转到开启位置处。所述凸轮轴和所述杆被设置在一四周突出的外壳8中。
所述支架尤其适合于所述前牙的根尖周X光照片,在图3中所示为一具有电缆10的数字传感器9在侧面被夹紧,并且所述臂被设计地在侧面上仅需要很小的空间。而且,在图3中所示为所述传感器夹紧部没有突出超过传感器9。
图1或图3示出了支架2的部分11,该部分的构造原理与专利文件EP-B-397599中所描述的支架的部分的构造原理是相似的。因此,当弹簧致动的X射线胶片夹紧部被图1中所示的夹紧部1更换时,咬合面和曲柄指示杆二者都与所引证的欧洲专利文件中的相同或者相似。
图4和图5图解了用于咬翼片X光照片的支架,该支架包括一传感器夹紧部,而不是X射线胶片夹紧部。在其它的支架中,用于咬翼片X光照片的X射线胶片的支架在现有技术领域中是公知的技术,并且由本发明的申请人销售已久。所以,在图4和图5中没有被图解的或者是没有被完全图解的部件,例如所述曲柄指示杆,就没有进行更详细地描述。根据图1至图3,和所述传感器夹紧部类似的,所述臂也是对称地移动,所以所述传感器总是以相同的方式独立于所述传感器的尺寸与所述指示杆排成一条直线,所述指示杆对应于各自的X射线管。
图4中,在没有遮盖物的情况下,传感器夹紧部12被示意性地图解,并且可以看到具有钳子14,14A的两个臂13,13A。所述臂的下面是具有齿条15,15A的弯曲部分,这两个齿条相互啮合在一起。而且,在图4中,可以看到指示杆16的一部分。所述齿条的移动受到一掣子17的影响,所述掣子可以自锁,所以所述臂可保持在它们所到达的任何位置处。而且,所述掣子包括一复位弹簧18,由此所述掣子的一端可不变地作用在一个弯曲齿条上,所以,提供了一自锁作用。所述掣子接通枢轴19。
利用弯曲齿条的解决方法允许将整个扩展机构和锁定机构设计得十分细长,由此,允许将咬合面20设计得十分细长,如图5所示该咬合面通过所述机构的四周突出的外壳形成,所以,整个支架对患者而言比先前的支架更令人感到舒适。各自具有夹紧爪的臂被设计得以使它们能容纳任何几何外形的传感器,即,如在图5中清楚所示地,它们可是棱柱状外形,所述夹紧爪具有钳子。
在所述实施例的一个变体中,橡胶垫21被插在钳子14,14A上。出于这个目的,如果所述钳子具有一种该橡胶垫可被保持的构造,那么这将是有益的。
在图6至图8中,图解了用于后牙(侧牙)的根尖周传感器的支架的第二实施例,其中所述传感器自底向上被夹紧,而不是如在前面的例证实施例中所述的从侧边被夹紧。
传感器夹紧部22可被安装在如前面的实例中所述的相同的支架上,即,所述金属板被直接地安装在邻近咬合面处。所述传感器夹紧部包括一壁23,该壁上有两个一体成形的专门用来保持所述传感器的钳子24,24A。在所述夹紧部的下部,设置有一夹紧爪25,为了夹紧所述传感器,所述夹紧爪按照箭头26的方向可向上移动。在一导锁部分28上设置有一锁定旋纽27,该导锁部分包括一倾斜面29,该倾斜面可致动夹紧爪25的另一个倾斜面30。
在所示附图中,当导锁部分28从右边被移动到左边时,所述夹紧爪被向上推动。如图8所示,两个倾斜面29,30都具有小齿31,该小齿可阻止所述两个倾斜面在彼此上的任何移动,所以所述夹紧爪总是保持在一调整过的位置上。所述自动锁定机构通过一开启运动被释放,在该开启运动中,附着力被克服。所述夹紧机构是节省空间的,所以所述支架是细长的并且不会被干扰。
图7还图示了这种传感器夹紧部可被设置在现有技术的一支架上,而不是通常的胶片夹紧部。在支架32的图解中显示了指示杆33的一部分。所述夹紧机构被容纳在一四周突出的外壳34中。
本发明中所有的传感器夹紧部的共同之处在于,它们都能确保数字传感器不受问题困扰的和精确的保持,所述传感器具有卫生袋或者其它的保护外壳,并且它们在所述传感器和所述X射线管之间都没有别的塑性材料的存在。同样,正如所清楚描述的,它们可以保持各种尺寸的传感器。而且,如所描述的,因为所述臂一直能被开启以容纳所述传感器并随后保持它,所以所述传感器总是被抓住,而不是被推进所述夹紧部的。
