Description

Operation fixing table for exposing neck/abdomen of mouse Technical Field The utility model relates to the technical field of animal operating tables, in particular to an operating fixing table for exposing the neck/abdomen of a mouse. Background In order to obtain new knowledge about biology, medicine, etc. or solve specific problems, scientific research is generally performed using animals. The final goal of experimental animal scientific development is to study the life phenomena of animals, further promote the animals to human beings, control diseases and aging of the human beings and prolong the life of the human beings. The mice are the most commonly used experimental animals, so that a plurality of operating tables or dissecting tables special for experiments on the rats and the mice are presented, and nails connected to the operating tables through belts are generally used for binding the limbs of the mice for fixing, so that the fixing mode of the mice is generally difficult to adjust for the mice of different ages, and discomfort and damage to the animals are easily caused, so that the accuracy of the experimental results is affected.
