Description

Technical Field

The invention relates to the technical field of laser cutting equipment, and in particular to a laser cutting device for amniotic membrane shaping.

Background Art

With the progress of relevant science and technology such as human biology and medicine, the research on biomembranes has also been further expanded. Due to the physical properties of biomembranes, especially their viscoelasticity, the preparation of standard biomembrane samples is relatively difficult. Most of the existing experiments on amniotic membranes use manual cutting to prepare samples, which will destroy the mechanical properties of the amniotic membrane itself to a certain extent. In addition, manual preparation has problems of non-standardization and irregularity, which can easily affect the accuracy of experimental results, and is also accompanied by various problems such as bacterial contamination of samples;

At present, the existing cutting devices are still unable to manufacture amniotic membrane samples in a standardized manner. When cutting viscoelastic materials, the serrated blade will tear the materials around the cut and destroy the original physical properties. The amniotic membrane itself has a very low breaking limit, and its properties become more fragile after being destroyed, which reduces the quality of the amniotic membrane and is not conducive to its subsequent use.

DETAILED DESCRIPTION

The technical solution of the present invention will be described in detail below in conjunction with specific embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present invention.

Embodiment 1

As shown in FIGS. 1-5 and 7 , the present invention provides a laser cutting device for amniotic membrane shaping, comprising a support frame 1, a conveyor belt 11 is arranged at the upper end of the support frame 1, and a semiconductor cooling sheet 8 is arranged at the upper end of the conveyor belt 11;

Amniotic cells are thin membrane tissues, and irreversible thermal damage will still occur after low-power laser cutting. In particular, burning marks are easily produced at the cutting edge, thus affecting the ability of amniotic cells to expand and grow outward.

Secondly, during the tiling and processing of amniotic cells, the cells are easily affected by the ambient temperature and produce excessive proliferation/death and other properties. Therefore, the low temperature environment has a crucial impact on cell processing and reducing thermal burns in the whole process;

For the above reasons, a metal refrigeration module needs to be built under the amniotic cells. At the same time, considering that the compressor refrigerator is large in size, noisy, and the required refrigerant pipeline is complex and cannot be miniaturized. This design adopts the semiconductor refrigeration mode;

Semiconductor refrigeration is more widely used in biology and medicine. In biology, when observing and studying slices, it is generally required that the temperature of the object of observation should remain constant, and most of the time a low temperature is required. It is very wasteful to use conventional means to cool down or heat the entire laboratory. However, semiconductor refrigeration technology can be used to make a temperature-controlled microscope stage, which can be adjusted from -25 to 125°C with an accuracy of ±0.11°C, which can well meet the demanding temperature requirements;

1. It does not require any refrigerant, can work continuously, has no pollution source, has no rotating parts, will not produce a rotation effect, has no sliding parts, is a solid piece, has no vibration or noise when working, has a long service life, and is easy to install.

2. Semiconductor refrigeration chips have two functions, which are cooling and heating. The cooling efficiency is generally not high, but the heating efficiency is very high, which is always greater than 1. Therefore, one chip can replace the separate heating system and cooling system.

3. Semiconductor refrigeration chips are current transducer type chips. By controlling the input current, high-precision temperature control can be achieved. Combined with temperature detection and control methods, it is easy to achieve remote control, program control, and computer control, making it easy to form an automatic control system.

4. The thermal inertia of the semiconductor refrigeration chip is very small, and the cooling and heating time is very fast. When the hot end dissipates heat well and the cold end is unloaded, the refrigeration chip can reach the maximum temperature difference within less than one minute after power is turned on.

5. The reverse use of semiconductor refrigeration is temperature difference power generation. Semiconductor refrigeration is generally suitable for power generation in medium and low temperature areas.

6. The power of a single refrigeration element pair of a semiconductor refrigeration sheet is very small, but the volume is very small, and a single sheet device can perform refrigeration operations.

7. The temperature difference range of the semiconductor refrigeration chip can be achieved from positive temperature 90℃ to negative temperature 130℃.
