Background

Tissue chips (tissue chips), also called Tissue Microarrays (TMAs), are tissue sections made by arranging tens to thousands of small tissues neatly on a glass slide, and are another important biochip appearing after gene chips and protein chips, and are mainly used for studying the expression of the same gene or protein molecule in different cells or tissues. The marked tissue was arranged as designed on a blank wax block using a tissue chip spotter. Firstly, a drilling instrument is used for drilling holes on marked target sites, tissue cores are transferred into wax block holes, thousands of sample tissue cores can be transferred by repeated operation, and then a microtome is used for continuously slicing the array wax block to obtain tissue chips.

In the manufacturing process of the tissue chip, the area of the wax block is small, the point arrangement of the tissue specimen is messy, and the waste of the limited area of the wax block is serious. The existing preparation process mostly adopts a hollow needle to extract the wax core of a blank wax block, and has the biggest defect that the wall of the needle has certain thickness, occupies small space on the wax block with limited area in the space of 1/100 mm and 1/1000mm, and causes great waste; after the hollow needle takes out the wax block core, the wax core needs to be pushed out, and the following same operations can be carried out again, which is tedious and time-consuming. The existing fixator moves transversely and longitudinally, two suspended springs are adopted for pulling and fixing, the accuracy is obviously reduced, when the springs are pulled open, the moving accuracy of the fixator is still higher, but when the springs retract, the movement is obviously unbalanced; in the wax block manufacturing process, the wax block often needs to be suspended or retreated in the forward moving process, when the wax block moves forwards again, obvious deviation occurs, accurate positioning cannot be achieved, even the arrangement form is completely disturbed, and a large amount of manpower and material resources are wasted.
