Abstract

The utility model provides a biological tissue supporting bracket of a pathologic slicing machine, which solves the problems that the biological tissue only can be lain on an objective table of the existing pathologic slicing machine; interfaces of each layer of the pathologic tissue is parallel with the direction of relative movement of a knife tool of the slicing machine; ideal slicing faces can not be obtain on the direction which is vertical with the interfaces of each layer, etc. The utility model is composed of a base and an objective slice, wherein the base is fixed on the objective table of the slicing machine; the objective slice is vertical with a plane; the base is positioned on the plane; the base is connected with the objective slice into integration. The biological tissue can be vertically put on the objective table by the supporting bracket of the utility model. The slicing faces of each slicing have clear tissue layers and regular boundary line. The utility model not only can clear show lamellar anatomic structures of the biological tissue, is still more favorable to excavate and separate the objective tissue or objective cells from the slicing and is particularly suitable for slicing the flat biological tissue with the lamellar structure.

Description

Microtome biological tissue carrying support

Technical field

The utility model relates to a kind of support, relates in particular to a kind of biological tissue's carrying support of pathological section machine.

Background technology

Medically, in order to carry out pathological diagnosis, need carry out slicing treatment to the sample tissue of being got, at present, most widely used pathological section machine has two kinds in paraffin slicing machine under the normal temperature and constant temperature quick freezing type microtome.These two kinds of microtomes all are to be made of objective table and cutter, the mode that during work biological tissue is adopted paraffin-embedded mode or freeze is fixed on the objective table, objective table constantly static relatively cutter moves back and forth, thereby biological tissue is progressively cut, and the direction of stage movement is substantially parallel with the plane at objective table place.Cut like this pathological section can satisfy the requirement that hospital carries out pathological examination substantially, because hospital's pathological examination mainly is to observe the degree whether section exists sick cell or observation of cell pathology, in this case, generally needn't require pathological section to have specific angle or the direction of cutting.And for medically will study flat and when having the pathology of layer structure tissue (as skin or mucous membrane etc.), the tangent plane of the section that requirement always obtains is vertical with the interface of organizing each interlayer, and the clear layer of each interlayer is clearly demarcated, the interface is smooth, so that tangent plane can show the stratiform anatomical structure of organizing each interlayer exactly, sometimes also wish and at microscopically destination organization or target cell to be separated, take out, in this case, if directly biological tissue is tiled on the micro slide, promptly the direction of this tissue tiling is substantially parallel with the direction of cutting, the tangent plane that obtains like this organizes the interface between each layer parallel with flat, the section that obtains is likely certain one deck of flat tissue, can't obtain desirable tangent plane from direction perpendicular to each bed interface, in addition, be fixed on the objective table with at random natural form if will this tissue, the tangent plane of gained section then, it organizes the interface of each layer will gauffer, out-of-flatness, it is accurate with destination organization or target cell to be difficult at microscopically, convenient, separate quickly, take out.

Summary of the invention

The purpose of this utility model provides a kind of biological tissue carrying support of microtome, and this support is applicable to flat and has cutting of layer structure biological tissue, it can make cut section tangent plane tissue each layer by layer time clearly, the boundary line is clear smooth.

For realizing above purpose, biological tissue of the present utility model carrying support, it is characterized in that: described carrying support is made of a base and a micro slide perpendicular to this plane, base place that is used for fixing on the microtome objective table, and base and micro slide are connected as a single entity.

Above-mentioned micro slide can be with biological tissue's slitting.

Macromolecular materials such as the preferred plastics of the material of above-mentioned micro slide, organic glass.

Above-mentioned base is " one " font schistose texture, and base and micro slide constitute is inverted the T font.

Make in order to save starting material and to be convenient to, above-mentioned base is " product " font schistose texture.

Biological tissue of the present utility model carrying support, because micro slide is perpendicular to plane, base place, also promptly perpendicular to the plane at objective table place, biological tissue flattens, is close on the micro slide, interface between each layer of flat tissue is just vertical substantially with the formed track plane of blade preceding forward line relative motion like this, the tangent plane of gained section, each is inferior layer by layer clearly demarcated for its tissue, the boundary line is smooth, can not only be clear the stratiform anatomical structure of this biological tissue of displaying, more help destination organization or target cell being taken, separating from section at microscopically.And micro slide can be cut with biological tissue, the carrying support just can select to make plane, the micro slide place angle parallel with the direction of stage movement to place, like this on the cutter application point of the knife edge just at the sidewall of micro slide, the thrust that the carrying support is subjected in working angles is just less, makes whole stock removal action comparatively steady.

Description of drawings

Fig. 1 is a kind of structural drawing of the utility model biological tissue carrying support.

Fig. 2 is the another kind of structural drawing of the utility model biological tissue carrying support.

Fig. 3 is that this carrying support is fixed in the working state figure on the objective table.

Specific embodiment

As shown in Figure 1, biological tissue of the present utility model carrying support is made of base 1 and micro slide 2, base 1 and micro slide 2 are plates, orthogonal, constitute an inverted T font support, base 1 adheres to its bottom surface on the objective table of microtome, micro slide 2 smooth surfaces, biological tissue is close on it, and micro slide 2 can be with biological tissue's slitting in working angles.Make in order to save starting material and to be convenient to, base 1 also can be made into the structure that is " product " font, as shown in Figure 2.The material of base and micro slide adopts plastic tab or organic glass thin slice, and is one-body molded.

During work, flatten, be tiled in flat biological tissue 3 on the micro slide 2 of carrying support, at low temperatures, biological tissue is frozen in (or adopting paraffin that biological tissue's embedding is fixed on the micro slide 2) on the micro slide 2, the bottom surface of carrying bracket base 1 is cemented on the objective table 4 of microtome, make plane, micro slide place substantially parallel with the direction of stage movement, what be close to micro slide like this organizes the interface between each layer just vertical substantially with the formed track plane of the preceding forward line of blade ab relative motion, as shown in Figure 3.When the continuous static relatively cutter 5 of objective table moved back and forth, micro slide was progressively cut with biological tissue, and the biologic slice of gained from its tangent plane, can see that then this biological tissue is respectively inferior layer by layer clearly, the boundary line is smooth, gauffer can not take place.
