具体实施方式:
如图 1-4所示,一种体部 CT精密定位穿剌装置, 其特征在于该装置包括一 个调节架 1, 固定于该调节架 1上的方框形的基底框 2, 以及安置于该基底框 2 框内且长度宽度分别相等的定位板 3和穿剌板 4, 所述的定位板 3 内装有等间 距且横向排列的定位坐标线 5, 所述的穿剌板 4上贯穿有与定位坐标线 5相对 应的等距离穿剌孔 6, 每相邻两排穿剌孔 6的间距均等于定位坐标线 5的间距。
考虑到临床穿剌中会有不同的穿剌角度, 上述穿剌板 4内的穿剌孔 6的水 平倾斜度是 15 ° 、 30 ° 、 45 ° 和 90 ° , 即需要四种不同角度的穿剌板 4。
如图 1、 2所示, 考虑到确保定位板与穿剌板的稳定和准确, 上述基底框 2 相邻的一组框边上分别设有一个水平仪 7, 以便使基底框 2可以调整至水平。 如图 3、 4所示, 考虑到采用便于计算的标准单位尺寸, 上述定位板 3和穿 剌板 4的长宽均为 10cm, 定位坐标线 5的间距为 lcm, 且最外侧的两条定位坐 标线 5距定位板 3两条横边也是 lcm, 即定位板 3和穿剌板 4相互叠合后, 定 位板 3内的定位坐标线 5与其对应的一排穿剌孔 6相互重合。 如图 4所示, 此 时穿剌板 4上有 9 X 9=81个穿剌孔 6, 且每相邻两排穿剌孔 6的间距是 lcm。 上述定位板 3 内的定位坐标线 5可以采用常规的能够在 CT扫描底片中留下影 像的材料。
考虑到穿剌进针的方便, 上述穿剌板 4的穿剌孔 6的顶端有倒锥形的凹陷 结构, 该凹陷结构自穿剌板 4的上表面向下收缩至穿剌孔 6直径的宽度。
如图 4所示, 考虑到便于 CT射线穿透以及观察定位和穿剌情况, 上述基 底框 2、 定位板 3和穿剌板 4是透 CT射线的透明有机玻璃制成。
如图 1所示,考虑到使基底框及其定位板和穿剌板在三维空间内灵活调整, 上述调节架 1包括固定有竖向调节杆 9的底座 8、 和滑动固定在竖向调节杆 9 上的横向调节杆 10, 以及滑动固定在横向调节杆 10上的纵向调节杆 11, 这种 结构可以使基底框 2迅速移动到患者病灶上方。
考虑到基底框与调节架的稳定连接, 上述基底框 2与调剂架 1之间设有连 接器 12, 所述的连接器 12是将基底框 2固定在调剂架 1的纵向调节杆 11上的 连接装置, 连接器 12可以是一端经由燕尾槽、 隼与基底框 2相连接, 另一端经 由螺丝与调节架 1相连接。
如图 1所示, 考虑到使整个装置保持稳定, 上述调节架 1的底座 8内装有 铅块, 且底座 8的底部粘有防滑的毡垫 13。
CT扫描是对病灶逐层扫描, 并得到数个病灶的截面视图。使用本发明进行 定位时, 是将内含定位坐标线 5的定位板 3置于病灶上方一同进入 CT扫描架 进行扫描, 之后会得到数个层间距为 1cm且上方带有定位坐标线 5影像的病灶 截面图, 因采用逐层扫描, 定位坐标线 5的影像是一个个点, 其中每一个截面 图里的位于病灶正上方的定位坐标线 5所对应的穿剌孔 6的位置就是待穿剌点。 将每一个截面图所确定的待穿剌点标记在点位坐标示图板 14上,从而得到全部 的待穿剌点的准确定位。
利用上述体部 CT精密定位穿剌装置进行定位的方法, 如下:
( 1 )将该定位穿剌装置放置于 CT扫描床面上,将定位板 3装入基底框 2内, 使定位坐标线 5与 CT扫描的截面相垂直, 并且定位板 3置于患者病灶上方, 调整基底框 2上的两个水平仪 7使基底框 2保持水平; 可将本定位装置置于患 者两腿中间, 则纵向调节杆 11可直接伸向患者体部上方, 保持患者、 CT扫描 床与本装置在 CT扫描时做到三者相对位置始终保持不变。 (2)待 CT扫描机发出纵向、 横向红外测量线后, 使定位板 3朝向 CT扫描 架的一边与 CT横向红外测量线保持重合, 将此线作为 CT扫描基准线, 从而 确保了定位的层面深度及角度的准确性和一致性。
(3 ) 经 CT扫描后得到带有病灶层面的数个影像底片, 根据定位坐标线 5显 示在影像底片上的点位, 而确定每个病灶层面上的定位坐标点、 即待穿剌点, 以及病灶在该层面所处的深度及角度; 其中影像底片的数量将视病灶的大小而 定, 病灶越大, 层面数量就越多, 扫描后得到的影像底片数量也越多。
(4)根据上述每一个层面所确定的待穿剌点、和位于该点下方的病灶层面深 度及角度, 而确定病灶的所有待穿剌点, 将每一个待穿剌点及其下方的病灶层 面深度及角度标注在与穿剌板一致的点位坐标示图板 14上即完成了定位。
由于穿剌板 4的穿剌孔 6的影像在 CT扫描影像中也清晰可见, 并且穿剌 孔 6与定位板 3内的定位坐标线 5相对应, 因此还可以直接用以穿剌板 4代替 定位板 3装入基底框 2中进行 CT扫描定位。
以扫描胸腔的病灶为例, 将本发明的穿剌板 4 (或定位板 3 )置于病灶正上 方, 假设经扫描后 CT900 层是首个出现病灶的截面, 并且总共得到 CT900〜 CT960共七个带有病灶的截面。 其中 CT930层的病灶剖面影像 17与胸腔剖面 影像 18如图 5所示。 出现在病灶剖面影像 17正上方的穿剌孔 6 (或定位坐标 线 5 )所对应的点位就是 CT930层的待穿剌点, 而对应于该 CT930层的待穿剌 点位就是图 5中标有纵向坐标线 15的四个穿剌孔 6, 可以看出该四个穿剌孔 6 依次为左数第 3至第 6个穿剌孔 6。
并可将该 CT930层的四个待穿剌点的位置经纵向坐标线 15标注在如图 6 所示的点位坐标示图板 14上, 从而确定 CT930层面的四个待穿剌点 19在点位 坐标示图板 14上的坐标。 并且在点位坐标示图板 14的方格内记录 CT扫描测 得的病灶进针的深度及角度, 即完成该层面的定位。
除 CT930层面的其他六个层面的待穿剌点也是用同样的方式确定并标注在 点位坐标示图板 14上, 当全部完成后即可进行精确穿剌。
利用上述的体部 CT精密定位穿剌装置在定位后进行穿剌的方法, 如下:
( 5 )完成定位后将定位板 3取出,更换为根据测量结果所需角度的穿剌板 4, 再根据每一个点位坐标示图板 14上所标注的点位在穿剌板 4上一次性完成各个 层面的穿剌进针。
