Technical Problem
但是制作成冰冻切片需要花费一些时间，且如果要了解组织块不同方向上的病理情况还需要对组织的各个面都进行切割并制作成切片；还有一些病灶比较大且分散的组织，医生很难做到对所有可疑部位都切割一小块；例如皮肤癌的样本通常是含有较厚皮下脂肪的大块组织，其中可能分散着多处肿瘤病灶，但脂肪组织通常坑坑洼洼，病理科医生很难判断组织的切缘，也很难对脂肪进行进一步的切割，因此难以制成冰冻切片，即使能切下部分的小块组织，由于术中病理的时间紧迫，也有很难做到对所有可疑部位都取样并制作冰冻切片进行分析

Abstract
The application discloses a sampling set for target substances on the surface of a tissue block, which comprises a deformable material and an adsorptive slide, and further comprises one or more of a fixing tray, a positioning auxiliary tool, an isolation film and a transparent soft film. The set realizes the transfer of the target substances on the surface of the tissue block to the surface of the smooth and flat slide through the transfer of the deformable material, is suitable for various tissue samples with flat or uneven surfaces, and the collected target substances can be directly used for the next detection and analysis. The set can be used for intraoperative rapid pathological diagnosis, and is convenient for surgeons to quickly obtain a diagnosis result in operation, so that lesion resection or accurate sampling can be performed.
