Description

空心轴直线电机 技术领域
本实用新型涉及直线电机，尤其涉及空心轴直线电机。
背景技术
内窥镜是集中了传统光学、人体工程学、精密机械、现代电子、数学、软件等于一体的检测仪器，包括图像传感器、光学镜头、光源照明、机械装置，可以经口腔进入胃内或经其他天然孔道进入体内。使用时将内窥镜的用于扫描人体内部器官的探头经内窥镜的工作通道导入，以扫描预检查的器官，可直接窥视有关部位的变化，探头获得图像质量的好坏将直接影响着内窥镜的使用效果，例如，借助内窥镜医生可以观察胃内的溃疡或肿瘤，据此制定出最佳的治疗方案。
为逐层扫描预检查器官，需要伸缩移动探头来逐层扫描器官，但是，若用现有常规直线电机来带动探头伸缩，由于直线电机的轴杆一般用作推杆，与其联动的部件只能安装于该轴杆端部，因此，探头将很容易与直线电机发生摩擦或干涉，影响探头的准确移动。
实用新型内容
为了克服现有技术的不足，本实用新型的目的在于提供空心轴直线电机，能方便地、顺畅地穿接并联动管件，防止管件摩擦干涉。
本实用新型的目的采用以下技术方案实现：
空心轴直线电机，包括轴杆、电机壳、均置于该电机壳内的动子、定子，动子和定子电磁配合，轴杆与动子联动并沿动子运动方向伸缩，该轴杆贯穿电机壳且由电机壳的两端伸出，该轴杆内开有用于穿接外 部管件的贯穿孔，该贯穿孔沿轴杆的轴向延伸。
优选地，轴杆的一端螺接有用于箍紧外部管件的固定环。
优选地，远离固定环的轴杆另一端被内置于一套管内，该套管的一端用作可拆卸的固定端。
优选地，套管一侧铰接有箍圈。
优选地，箍圈包括半圆形的第一半圈和半圆形的第二半圈，第一半圈的一端与箍圈铰接，第二半圈的一端与第一半圈的一端弹性铰接，第一半圈的另一端与第二半圈的另一端相对。
相比现有技术，本实用新型的有益效果在于：
本实用新型通过在轴杆内开设贯穿孔，使外部管件(如探测用的探头管)可以方便、顺畅地穿接进入轴杆，与轴杆同步联动伸缩，可防止管件与电机其它部位发生摩擦干涉，利于对管件移动量进行精准控制。

具体实施方式
下面，结合附图以及具体实施方式，对本实用新型做进一步描述：
如图1～2所示的空心轴直线电机，包括轴杆1、电机壳2、均置 于该电机壳2内的动子(图中未示出)、定子(图中未示出)，动子和定子电磁配合，轴杆1与动子联动并沿动子运动方向伸缩，该轴杆1贯穿电机壳2且由电机壳2的两端伸出，该轴杆1内开有用于穿接外部管件6的贯穿孔11，该贯穿孔11沿轴杆1的轴向延伸。
通过在轴杆1内开设贯穿孔11，使外部管件6(如探测扫描用的探头)可以方便、顺畅地穿接进入轴杆1，与轴杆1同步联动伸缩，可防止管件6与电机其它部位发生摩擦干涉，利于对管件6移动量进行精准控制。
管件6可以是用于扫描人体内部器官的探头管，接入不同的光学分析仪器以获得不同的图形成像，例如，可用作纤维支气管镜的导管，或者用作胃镜的导光纤维管，或者椎弓根镜的光纤探管，或者OCT(光学相干断层扫描仪)的探管。管件6也可以用作治疗人体内部器官的治疗管，可接入如射频加热治疗装置、激光烧灼治疗装置、超声振动剥离装置,、外科手术治疗装置来输出治疗动作，通过上述精确伸缩微调关键6，来精准输出治疗动作。
定子通电后，动子将产生轴向位移，带动轴杆1(或称推杆)伸缩移动，从而使与该轴杆1传动连接的管件6(探头)也相应伸缩移动。对应可将该直线电机的反馈端经电源线缆7接至外部控制分析仪器，以更精准地控制管件6(探头)的伸缩位移量。
作为一个优选的实施方式，轴杆1的一端螺接有用于箍紧外部管件6的固定环3，该固定环3可更方便地可拆卸固定管件6。
