Abstract

The invention provides a quick refrigerating device which is mainly characterized in that a tissue positioning frame is the front wall of an evaporator, the evaporator is a cavity, the rear wall of the evaporator is in brazed connection with the cavity, the rear wall of the evaporator is in screwed connection with a spherical steering piece, the rear end of the spherical surface is in screwed connection with a locking shaft, a metal hose is in brazed connection with the lower end of the evaporator, the locking shaft is inserted into a central hole of the steering piece and is fixedly positioned by a positioning screw, an eccentric shaft is inserted into an eccentric shaft hole and passes through the locking shaft hole, a horizontal adjusting knob is screwed into a horizontal adjusting knob hole, a vertical adjusting knob is screwed into a vertical adjusting knob hole, and the eccentric shaft is fixedly provided with the evaporator with the tissue positioning frame. The rotary blade has the advantages that the rotary blade has a steering function and a refrigerating function, the blade also has a refrigerating function, the refrigerating function is realized by using a compressor, the refrigerating speed is high, precooling is not needed, and the rotary blade can be started to operate slicing at any time. The direction adjustment of the slicing surface is realized by the steering function, so that the sliced tissues can be sliced in multiple angles. Thereby obtaining the optimal lesion position of the sliced tissues.

Description

Quick refrigerating device

The technical field is as follows:

the invention relates to a quick refrigerating device, in particular to a quick refrigerating device for pathological tissue slices.

Background

The prior quick slicing device for biological tissues has refrigeration at the slicing head, but has no turning direction, the prior freezing microtome sold in the market has no refrigeration function, but has a turning function, the freezing microtome can not carry out quick refrigeration without the refrigeration function, the prior freezing microtome is refrigerated by a freezing box, so that the cooling speed of the freezing head is low, about 4-5 hours are needed, the prior freezing microtome needs to be started up day and night for timely slicing, not only energy is wasted, but also great trouble is brought to work. In addition, the semiconductor is used for cooling the refrigerating head, the cooling effect is extremely poor, and the refrigerating system is easy to damage. Disclosure of Invention

The invention aims to provide a quick refrigerating device aiming at the defects in the technology. The blade has the advantages that the blade has a steering function and a refrigerating function, the blade also has the refrigerating function, the refrigerating function is realized by using a compressor, the refrigerating speed is high, precooling is not needed, and the blade can be started to operate at any time. The direction adjustment of the slicing surface is realized by the steering function, so that the sliced tissues can be sliced in multiple angles. Thereby obtaining the optimal lesion position of the sliced tissues.

The invention aims to realize the purpose, which comprises a fixed handle, a clamping block, a tissue positioning frame, an evaporator, a metal hose, a spherical steering piece, a locking shaft, a steering piece, an eccentric shaft, a positioning screw, a horizontal adjusting knob, a vertical adjusting knob and a heat insulation sleeve. The eccentric shaft is inserted into the eccentric shaft hole and penetrates through the locking shaft hole, the horizontal adjusting knob is screwed into the horizontal adjusting knob hole, and the vertical adjusting knob is screwed into the vertical adjusting knob hole. The eccentric shaft is fixed with an evaporator with a tissue positioning frame. The heat insulating sleeve is arranged outside the steering piece to insulate cold temperature. The compressor refrigerating device is arranged at the lower end of the casing body of the machine shell.

The invention has the advantages of novel structure, simple process, complete functions, steering function and refrigeration function, and the cutter also has the refrigeration function, the refrigeration function is refrigeration by using a compressor, the refrigeration speed is high, precooling is not needed, and the slicing can be operated by starting up at any time. The direction adjustment of the slicing surface is realized by the steering function, so that the sliced tissues can be sliced in multiple angles. Thereby obtaining the optimal lesion position of the sliced tissues.
