Production apparatus for blank acceptor wax block of porous tissue chip

Abstract

The invention discloses a device for preparing a blank receptive block of a tissue chip with holes. The device comprises a pore plate, columnar fine needles and a detachable rectangular bulkhead which forms a box structure together with the pore plate, wherein, the pore plate is provided with through holes which are regularly arranged in rows; the through holes are T-shaped through holes composedof fine holes and big holes, which are vertically communicated; accordingly, the columnar fine needles are reducing needles which are embedded in and pass through the T-shaped through holes; at leastthe thin part length of one reducing needle is longer than vertical lengths of fine holes and the thick part lengths of the reducing needles are longer than vertical lengths of big holes. The device can effectively determine the axial position of a needle and strictly control the punching depth on the basis of realizing one-step molding; the punching accuracy is easy to control; the holes have noburrs or chap; finished wax block products are not damaged during the production, and the uniformity of punching on the wax block is ensured, so that the production quality of the wax block is ensured and the work efficiency is improved while time and labor are saved.

Description

technical field [0001] The invention relates to a medical testing device, in particular to a device for making a tissue chip blank acceptor wax block with holes. Background technique [0002] Tissue chip technology can analyze hundreds of tissue samples at the same time. It can maximize the use of tissue resources. It only needs to analyze a small core slice on the sample wax block instead of all slices. Using this technology, pathological Samples in the Tissue Block Bank make a well-designed display, a tissue array section made by arranging tens to thousands of small tissues on a slide by constructing a tissue array block. [0003] In the process of making the tissue chip, the method of making the blank receptor wax block is roughly the same, and the two sides of the produced receptor wax block are smooth and flat. When making a tissue chip, first use a punching needle to punch a hole on a blank acceptor wax block, and then use a spotting needle to put the donor tissue int...

Problems solved by technology

However, during the use of the mold with this structure, the core post is not easy to take out after the pouring wax solidifies, and the wax mold is easily damaged, causing burrs or cracks in each hole. The hole on the mold has a through hole, which makes it difficult to put in the donor tissue and the test process
