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...
