切片时为准确地切到组织，通常在包埋时组织会被轻轻 地压在包埋模的底部。针吸穿刺活检组织通常长10 ～ 20 mm，直径却＜ 1 mm，因此，即使有轻微的切削平面调节失误， 也很容易导致活检组织从一端被不均匀的切掉。当切片的对象为一个几乎透明的组织时，调节标准切削平面的问题可能会更复杂。另外，当组织蜡块分别在不同的切片机上切片 时，切削平面发生的变化会导致切片困难，比如，有些实验室在一台切片机上修切蜡块然后分发到其他切片机切片，或把蜡块送到外院进行会诊需要重新切片。在这些情况下，的切削平面和随后的切片机之间的误差，往往由于再次修切必然会导致组织不必要的损失。
　　In order to cut the tissue accurately, the tissue will be pressed on the bottom of the embedding mold. Needle aspiration biopsy usually has a length of 10-20 mm and a diameter of less than 1 mm. Therefore, even if there is a slight adjustment error in the cutting plane, it is easy to cause the biopsy tissue to be cut off unevenly from one end. The problem of adjusting the standard cutting plane may be more complicated when the object of the slice is an almost transparent tissue. In addition, when tissue wax blocks are sliced on different slicers, the change of cutting plane will cause slicing difficulties. For example, some laboratories cut wax blocks on one slicer and then distribute them to other slicers for slicing, or send the wax blocks to the outside hospital for consultation, which needs to be re sliced. In these cases, the error between the first cutting plane and the subsequent slicer will inevitably lead to unnecessary tissue loss due to re cutting.

　　每次正式切片操作前，按照操作规范，制备标准的石蜡组织模块，保证蜡块与模型底部平面平行，无前后左右 倾斜的现象; 其次，利用空白标准蜡块，分别将切片夹头调节 X 轴与刀刃接近平行，Y 轴与刀刃接近垂直; 如此得到的 切削平面我们称之为该切片机的标准切削平面。它可以相 对固定，保持不动，进行批量或连续处理切片操作时，可以在 一台或多台切片机上应用。该切片方式不仅规范和简化了 切片操作，避免因随意调节切削平面带来操作繁琐和不 因素，更主要的是极大地提高了切片的效率和切片的质量。
　　Before each formal slicing operation, firstly, prepare standard paraffin tissue module according to the operation specifications to ensure that the wax block is parallel to the bottom plane of the model, without the phenomenon of front and rear left and right inclination; secondly, use blank standard wax block to adjust the slicing chuck to the x-axis close to parallel to the blade, and the y-axis close to vertical to the blade; The cutting plane thus obtained is called the standard cutting plane of the slicer. It can be relatively fixed and kept still. It can be applied to one or more slicers when batch or continuous slicing operations are carried out. The slicing method not only standardizes and simplifies the slicing operation, avoids the tedious and unsafe factors caused by the arbitrary adjustment of cutting plane, but also greatly improves the efficiency and quality of slicing.

　　切片机切削平面的调节是通过 X 轴、Y 轴和锁定旋钮在内的 3 个主要调节旋纽完成。操作时松弛锁定旋钮，当得到满意的切削平面时，拧紧锁定旋钮，防止机械装置产生进一步的移动。对不同产地和型号的切片机来说，因安装的标本夹头和调节系统类型不同，调节切削平面的精确步骤可有轻微差异，操作人员可依据切片机使用手册做出调节。为了配合切削平面的顺利调节，在包埋组织时还应加强塑料包埋盒使用的操作规范，即待包埋模型底部石蜡开始凝固后再盖上包埋盒，待其四周凝固后进行二次加蜡。这样的目的是使得包埋盒与组织蜡块接触更加稳固，减少和防止切片时产生震颤或包埋盒与组织蜡块脱落。另外，还需注意的是二次加蜡
　　The adjustment of the cutting plane of the slicer is completed by three main adjusting buttons, including the x-axis, Y-axis and locking knob. During operation, loosen the locking knob. When a satisfactory cutting plane is obtained, tighten the locking knob to prevent further movement of the mechanism. For slicers of different origins and models, the precise steps of adjusting the cutting plane can be slightly different due to the different types of sample collets and adjustment systems installed. The operator can make adjustment according to the slicer's operation manual. In order to coordinate with the smooth adjustment of the cutting plane, the operation specification for the use of the plastic embedding box should also be strengthened when embedding the structure, that is, after the paraffin at the bottom of the embedding model begins to solidify, the embedding box should be covered, and after the solidification around it, the wax should be added twice. The purpose of this method is to make the contact between the embedding box and the tissue wax block more stable, reduce and prevent the chattering or falling off of the embedding box and the tissue wax block when slicing. In addition, pay attention to the secondary waxing
　　时不能过满，否则蜡块不能与切片机夹具完全吻合，造成切片时松动震颤，影响切片质量。
　　It should not be overfilled, otherwise the wax block can not be completely consistent with the fixture of the slicer, which will cause the loosening and shaking of the slicing and affect the quality of the slicing.
