Description

Refrigerator special for pathological paraffin section

Technical Field

The utility model relates to the field of medical inspection, in particular to a refrigerator special for pathological paraffin sections.

Background

Histopathological examination, i.e. biopsies, together with cytology fall into the category of pathological examination. Pathological section refers to pathological section made by pathological histology (usually embedding pathological tissue in paraffin block, slicing by slicing machine, staining with hematoxylin-eosin), further checking pathological change with microscope, and finally making pathological diagnosis. It is important to cut an excellent slide in the slicing step. In CNAS-GL048, the small biopsy tissue is required to be cut and fished for more than 6 continuous slices; post-processing projects (e.g., immunohistochemistry, FISH, gene detection, etc.) all require multiple serial sections. For a continuous slice of a wax block, the temperature of the wax block can rise, which directly leads to the crease of the following slice in the continuous slice, has poor quality and affects the diagnosis result. If the wax block is taken down and frozen for a few minutes, the wax block is taken out again, so that the efficiency and the progress of the preparation can be influenced, the time that a patient takes a pathological report and a result is prolonged, and the time for preventing and treating the patient is prolonged.

In order to solve the problems, the existing special freezing hammer for pathological sections is provided. The freezing hammer is firstly placed in a low-temperature environment for freezing, and then taken out when the paraffin needs to be cooled, and the handheld freezing hammer presses the paraffin to realize cooling. However, the existing freezing hammers are generally single metal blocks, and can rapidly heat up at room temperature. And the low temperature can cause discomfort to an operator when the hand is held, and the temperature of the operator can further increase the temperature rise of the freezing hammer. It is also difficult to grasp the pressing force with a single metal block.

The utility model of the prior application number 201320590429.1 provides a freezing hammer with a sleeve, and the gap between the freezing hammer and paraffin can be adjusted to achieve the best freezing effect. But every time the freezing hammer is adjusted, the freezing hammer needs to be rotated, the operation is inconvenient and the efficiency is low. And the sleeve adopted does not cover the freezing hammer completely, and the sleeve does not have a heat preservation effect.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model.

Referring to fig. 1, a cross-sectional view of a special refrigerator 1 for pathological paraffin sections is provided. The special pathological paraffin section refrigerator 1 comprises a sleeve 2, a freezing hammer 3, a connecting handle 4, a pressing handle 5 and a spring 6.

The sleeve 2 is a cylinder with one open end and one closed end, and is made of hard plastic with good heat preservation effect, so that the heating speed of the freezing hammer 3 is reduced, the cooling frequency in the refrigerator can be reduced, and the working efficiency is improved.

The sleeve 2 is provided with a through hole at the center of the closed end, and two observation windows 21 are arranged on the side wall. The viewing window 21 extends from the open end of the sleeve 2 to the closed end to a central position of the sleeve 2. The operator can observe the condition of pressing through observation window 21 in real time in the operation process, is convenient for in time adjust the dynamics of pressing, guarantees the quality of section film-making.

A transparent plastic plate is fixed in the observation window 21 to ensure that the sleeve 2 is still a closed whole after the observation window 21 is arranged so as to maintain the heat preservation effect.

The freezing hammer 3 is also a cylinder with one end open and one end closed, and is provided with a circular hammer cover 31 at the open end. The inner wall of the open end and the outer wall of the hammer cover 31 are provided with matched threads, and the two are connected through the threads. The freezing hammer 3 is made to form an internal hollow structure, substances with larger specific heat capacity can be filled in the freezing hammer, the temperature rising speed is further slowed down, and the working efficiency is improved.

The freezing hammer 3 and the hammer cover 31 are both made of aluminum alloy, so that the heat conduction speed is improved, and the paraffin can be cooled by pressing for a short time. The diameter of the freezing hammer 3 is consistent with the inner diameter of the sleeve 2, the height of the freezing hammer is smaller than the height of the inside of the sleeve 2, and the freezing hammer can be integrally inserted into the sleeve 2.

The connecting handle 4 is a round rod and is fixed at a center position of a surface of the hammer cover 31 away from the freezing hammer 3 at an angle coaxial with the hammer cover 31. The freezing hammer 3 is inserted into the sleeve 2 at an angle toward the inside of the sleeve 2 at the end provided with the hammer cover 31, and the connecting handle 4 passes through the through hole at the center position of the closed end of the sleeve 2. The end of the connecting shank 4 remote from the hammer cap 31 is provided with a thread.

The pressing handle 5 is screwed with the end of the connecting handle 4 away from the hammer cover 31. A spring 6 is sleeved outside the part of the connecting handle 4 between the sleeve 2 and the pressing handle 5. Under the thrust of the spring 6, the sleeve 2 and the pressing handle 5 are mutually far away, and meanwhile, the freezing hammer 3 is driven to move in the sleeve 2 towards the direction of the closed end of the sleeve 2 until the freezing hammer is abutted with the closed end of the sleeve 2.

Before use, the sleeve 2 is held by hand, the pressing handle 5 is pressed towards any fixed object, and the freezing hammer 3 is ejected out of the sleeve 2, so that the freezing hammer 3 can be screwed out of the hammer cover 31. The freezing hammer 3 is filled with water as a freezing liquid, and then screwed back onto the hammer cover 31.

The special refrigerator 1 for pathological paraffin sections is integrally placed in a refrigerator for freezing, so that water in the freezing hammer 3 is solidified into ice.

When in use, the special refrigerator 1 for pathological paraffin sections is taken out, and the sleeve 2 is covered on paraffin which needs to be subjected to cooling treatment. The sleeve 2 is held by one hand to be fixed, the pressing handle 5 is held by one hand to push the freezing hammer 3 to move downwards, and the pressing force is observed and adjusted through the observation window 21.

The heating speed is slower due to the larger specific heat capacity of water and the heat preservation effect of the sleeve 2. And the ice is always kept at zero degree in the melting process, so that the refrigerator 1 special for pathological paraffin sections can be used for a long time without being frequently put back into the refrigerator.

The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related arts are included in the scope of the present utility model.
