Eggshell precise hole cutting device for chicken embryo experiment

Abstract

The invention provides an egg shell precise hole cutting device for a chicken embryo experiment. A rotating assembly mounted in a rigid shell with a shock absorbing foot pad drives a clamping assemblywith position adjustable and a to-be-cut eggshell to rotate, a rigid shell base plate is provided with a displacement assembly with an elastic drill bit for cutting the to-be-cut eggshell, and when aball head handle installed in a right shifting screw hole on the right side of the rigid shell is screwed in and screwed out, the shifting assembly and the elastic drill bit are driven to move left and right to cut holes on the to-be-cut eggshell; an absorption assembly with an umbrella-shaped suction opening installed on the left side of the rigid shell can adsorb eggshell debris through a negative pressure fan and a filter box body; and a rotation speed knob, a drill speed knob and a power switch which are mounted on the right side control panel of the rigid shell can adjust the rotation and cutting speed and start cutting. The device has the beneficial effects that the eggshell of the chicken embryo experiment can be subjected to undamaged inner membrane and fine and accurate hole cutting operation with standard round holes, and standardized egg-type chicken embryo urinary bladder membrane exposure scientific research and application can be stably and safely achieved.

Description

Technical field [0001] The invention relates to an eggshell precise opening and rounding device for chicken embryo experiments. Background technique [0002] As more and more scientific research experiments in natural science research such as medicine, zoology and bioengineering require the use of egg shells of birds, reptiles or poultry egg test products, such as drilling, observation and dissection, etc. , to ensure the stability and safety of the egg shells of egg test products during such operations, so as to obtain standardized egg test products for scientific research and application experiments, such as using chicken embryo allantoic membrane to conduct inoculation and culture research on viruses, vaccines, etc. or drugs Tests, etc., therefore, it is necessary to perform precise and precise hole-cutting operations on the eggshells of a large number of bird, reptile or poultry egg test products without damaging the inner membrane, with standard round holes. The hole o...

Problems solved by technology

[0002] Since more and more scientific research experiments in natural sciences such as medicine, zoology and bioengineering need to use the eggshells of birds, reptiles or poultry test eggs for scientific research such as opening holes, observation and dissection. , to ensure the stability and safety of the egg shell of the egg test product in such operations, so as to obtain standardized egg test products for scientific research and application experiments, such as the use of chicken embryo allantoic membranes for virus, vaccine, etc. inoculation and cultivation research or drugs Therefore, it is necessary to carry out the eggshell cutting of a large number of birds, reptiles or poultry egg test products without damaging the inner membrane, with fine and accurate hole-cutting operations with standard round holes, all The opening of the hole requires the same size standard as the round hole, so as to ensure the stable and safe realization of the scientific research and application of standardized chicken embryo allantoic membrane exposure. Eggshells of similar test products or placed in simple protective gear for careful opening, observation and dissection operations. Because the eggshell is hard, the inner membrane and embryonic tissue are very soft and delicate. If the eggshell cannot be held stably and safely, it will be difficult to control and protect the inner membrane of the eggshell and the embryonic tissue. In order to prevent the eggshell from breaking, every step of the operation requires meticulous care and certain technical difficulties. The technical requirements for manual operation are relatively high, and it is difficult. To achieve perfect consistency, scientific standardization and non-standard damage rate is high, and manual operation also consumes a lot of time and manpower, which affects the scientific experiment operation to a certain extent and easily pollutes the operator, especially when conducting large-scale scientific research experiments. Complete the tasks of drilling, observing and dissecting a large number of egg test products, so that it cannot adapt to the current large-scale scientific research experiments and increasingly refined sample quality requirements, which affects the quality and safety of scientific experiment operations to a certain extent , hindered the in-depth development of related research, in order to overcome the above difficulties, fundamentally solve the problem of opening holes, observing and dissecting egg shells of large quantities of birds, reptiles or poultry egg test samples in scientific research and experiments. It is not easy to realize the standard, stable and safe hole-cutting operation of the shell, so as to achieve the eggshell experiment of chicken embryo experiment, which does not damage the inner membrane, the precise and accurate hole-cutting operation with standard round holes, and completes the standardized egg shell. The scientific research and application of chick embryo allantoic membrane exposure meet the needs of large-scale scientific experiments and increasingly refined sample quality requirements. It is inevitable and urgent to develop a precise eggshell cutting device for chicken embryo experiments. needs
