Abstract

The utility model relates to a semiconductor constant freezing slice machine, which is used for manufacturing a medical instrument of the pathological frezzing slice. The semiconductor constant freezing slice machine comprises an object stand portion and a freezing device of a slice knife. A refrigerator of the freezing device of the slice knife is arranged on the rear side of the slice knife; a cold plate is separated in the middle of the slice knife of the refrigerator, and the other surface of the refrigerator is contacted with the external wall of a water tank. A tissue slice which is made by the semiconductor constant freezing slice machine can not dissolve; operation is convenient; icing speed of the cold knife is fast; low-temperature performance is stable; after the tissue which needs to be checked is arranged on the object stand for two to three minutes, the semiconductor constant freezing slice machine can cut out uniform large slices which can not dissolve; the semiconductor constant freezing slice machine can continuously slice; the slice can not roll, and the tissue can not fall off. The semiconductor constant freezing slice machine can be provided with disposable cutting blades and pathological slice knives with different specifications, and installation is convenient.

Description

The permanent icy microtome that freezes of quasiconductor

This utility model relates to a kind of Medical Instruments that is used to make the pathology frozen section, the permanent icy microtome that freezes of particularly a kind of quasiconductor.

The semiconductor freezing microtome that present existing Jinhua, Zhejiang radio factory produces, its cryoprobe refrigerator is installed in the front of microtome knife, brings obstacle to film-making work, and it is very inconvenient to work together; Its microtome knife does not freeze, and causes dissolving immediately to cryoprobe from the tissue slice of cold cutting-out, can not serial section, so chipping qualities is relatively poor; In addition, old product is not installed the equipment of disposable blade.

The purpose of this utility model provides a kind of shortcoming that overcomes above-mentioned old product, and is easy to use, microtome knife is frozen fast, and the permanent icy microtome that freezes of quasiconductor of disposable blade can be installed.

For achieving the above object, the technical solution of the utility model is: the permanent icy microtome that freezes of a kind of quasiconductor, comprise border this TV station part and the freezing device of microtome knife, the freezing device of microtome knife comprises water tank (1), refrigerator (2), cold drawing (3), refrigerator (2) is installed in the back of microtome knife (5), microtome knife (5) is separated with cold drawing (3) with refrigerator (2) is middle, and refrigerator (2) another side contacts with water tank (1) outer wall.

This utility model is owing to be installed in the back of microtome knife with the freezing device of microtome knife, but the insoluble serial section of tissue slice not only, and also work is convenient; The special semi-conducting material that adopts is made refrigerator, can be according to the difference of the size of microtome knife, thickness, area, manufacture the special cryoprobe refrigerator of different size, cryoprobe is frozen fast, temperature satisfies the requirement of pathology frozen section, and cryogenic property is stable, be put into by the inspection tissue and can cut uniform sheet in oblect stand 2-3 minute, and insoluble, but serial section, the not clot of cutting into slices, organize and do not come off, the freezing device of this microtome knife can be installed disposable blade, and the pathological section cutter of different size also can be installed, and easy for installation.

Fig. 1 is the side view of the freezing device of microtome knife of the present utility model.

Fig. 2 is the rearview of the freezing device of microtome knife of the present utility model.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:

The permanent icy microtome that freezes of quasiconductor comprises oblect stand part and the freezing device of microtome knife, and the refrigerator 2 of the freezing device of microtome knife is installed in the back of microtome knife 5, is separated with cold drawing 3 in the middle of microtome knife 5 and the refrigerator 2, and refrigerator 2 another sides contact with water tank 1 outer wall.Cold drawing 3 is provided with recessed poor 4, is the disposable blade frame, and disposable microtome knife can be installed, and the pathological section cutter of different size also can be installed.The one-level pile that the microtome knife refrigerator is made up of 127 pairs, 31 pairs semiconductor elements can adopt the serial or parallel connection mode.

Claims

1, the permanent icy microtome that freezes of a kind of quasiconductor, comprise oblect stand part and the freezing device of microtome knife, the freezing device of microtome knife comprises water tank (1), refrigerator (2), cold drawing (3), it is characterized in that described refrigerator (2) be installed in the back of microtome knife (5), microtome knife (5) is separated with cold drawing (3) with refrigerator (2) is middle, and refrigerator (2) another side contacts with water tank (1) outer wall.
