Abstract

The utility model discloses a paraffin embedding tool for fish tissue, relates to an embedding tool for biological tissue, in particular to the paraffin embedding tool for preparing fish tissue slices, and aims to solve the problems that when the conventional paraffin embedding tool for the fish tissue is used for embedding the fish tissue, a manufactured embedding block is difficult to correct, an embedding mold is difficultly separated from an embedding object, the manufactured embedding block is difficult to take out and easy to break, and a small number of tissue embedding blocks are manufactured by the conventional embedding mold and are not high enough, so research on the tissue auxology of fish which is required to be continuously sliced is difficult to carry out, and adaptability is low. The paraffin embedding tool for the fish tissue comprises a plurality of molds which are arranged in parallel and integrally made, wherein each mold consists of a first mold cavity, a second mold cavity, a third mold cavity, two upper outer edges and two lower outer edges, and the two upper outer edges are arranged oppositely along the length direction of the mold. The paraffin embedding tool for the fish tissue is applicable to paraffin embedding of the egg tissue of the fish.

Description

Technical field

The utility model relates to a kind of embedding instrument that is used for biological tissue, is specifically related to a kind of FFPE instrument of using when fish are organized film-making that is used to prepare.

Background technology

Existing fish are organized the FFPE mould of usefulness, and when being used for the fish organization embedding, wax liquid overflows easily, and is wayward; The organization embedding piece of making is not easy to revise, and is directed difficult, and embedding mould and embedding thing are not easy to break away from; The organization embedding piece of promptly making is difficult for taking out, and wax stone is split, and; The embedded block quantity of existing embedding Mold Making is few, and the height of embedded block is not enough, causes the tissue development research of some fish that needs serial section to be difficult for carrying out.

The utility model content

The purpose of the utility model is for solving the FFPE mould that existing fish are organized usefulness, and when being used for the fish organization embedding, the embedded block of making is not easy to revise; Embedding mould and embedding thing are not easy to break away from, and the embedded block of promptly making is difficult for taking out, easy fracture when embedded block takes out; And; The organization embedding number of blocks of existing embedding Mold Making is few, and the height of embedded block is not enough, causes the tissue development research of some fish that needs serial section to be difficult for carrying out; The problem of bad adaptability, and then a kind of FFPE instrument that is used for the fish tissue is provided.

The utility model is to address the above problem the technical scheme of taking to be: a kind of FFPE instrument that is used for the fish tissue of the utility model comprises a plurality of moulds; A plurality of moulds are set up in parallel and process one; Described each mould is made up of first die cavity, second die cavity, the 3rd die cavity, two last outer eaves and two following outer eaves; Outer eaves is oppositely arranged along the length direction of this mould on two; Two down outer eaves be processed with first die cavity, second die cavity and the 3rd die cavity along the Width setting of this mould in the zones that two are gone up outer eaves and two down outer eaves formation, the upper surface of first die cavity respectively with two upward outer eaves with two under outer eaves be connected; The bottom face of first die cavity is connected with the upper surface of second die cavity; The bottom face of second die cavity is connected with the upper surface of the 3rd die cavity, and the height of the height of first die cavity, second die cavity and the height of the 3rd die cavity increase progressively successively, and described each mould is a mould of plastics and one-body molded.

The beneficial effect of the utility model is: the utility model is reasonable in design, and the embedding instrument of the utility model adopts nonrigid plastic to make, and when being used for the fish organization embedding, the embedded block of making is revised easily; Embedding mould and embedding thing break away from easily, and the embedded block of promptly making takes out easily, and embedded block is difficult for splitting when taking out, and is easy to make; Simple to operate, the embedding instrument of the utility model comprises a plurality of embedding moulds, and embedded block making amount is many, and each mould is divided into three layers of die cavity; Compare two layers of die cavity of existing mold, be fit to the needs of the section of big or small film-making of making difference and different-thickness, adaptability is good, the mould good stability of three layers of die cavity; The height of three layers of die cavity increases progressively successively, and the height of first die cavity adapts with the height of the wax tool that carries the wax device, and second die cavity is between first die cavity and the 3rd die cavity; The size of the film-making that the height of the 3rd die cavity prepares is as required confirmed, so is provided with, and the wax tool is placed stable; Avoided the wax hydrorrhea to go out, wax liquid is controlled easily, is convenient to setting; Be convenient to the embedded block sections observation, the tissue development of the fish of the serial section of satisfying the demand is learned research, and adaptability is good.The embedding instrument embedding effect of the utility model is remarkable, biological tissue's film-making sharp outline of making, and section is through microscopic examination, and sample image is clear, structural integrity.
