An anatomical fixation device for experimental animals

Abstract

The invention discloses an anatomical fixation device for experimental animals, and mainly relates to the field of animal experiments. It includes a fixed chassis and connecting rods, the fixed chassis is a circular structure, a circular frame coaxial with it is provided on the peripheral side of the fixed chassis, and there are no less than 4 circular frames arrayed along the circumferential direction. The upper circular end surface of the fixed chassis is rotated with a rotating disk coaxial with it, the rotating disk is driven by electricity, and the sliding disk corresponding to the number of limiting grooves is provided on the rotating disk. The chute is a linear chute and arrayed along the circumference of the rotating disk, the extending direction of the chute does not coincide with the radial direction of the rotating disk, the connecting rod runs through the limiting groove, and one end of it is exposed outside the fixed chassis, The other end is slidingly matched with the chute. The beneficial effect of the present invention is that it can better fix the limbs of animals, the fixing effect is reliable, and the stretching state of the limbs after fixing can be adjusted easily, so that the experiment can be carried out smoothly.

Description

technical field [0001] The invention relates to the field of animal experiments, in particular to an anatomical fixation device for experimental animals. Background technique [0002] Animal dissection is a common technique in pathogen experiments and pathological experiments. It is a direct means to separate target tissues (tumors, etc.) and observe internal organs and tissue lesions. Generally, the operations that need to be performed are inseparable from the immobilization of the target animal. On the dissecting table, put the animal in a supine position (or prone position if required) on the experimental table, fix the limbs with nails, and dissect. This fixation method is not reliable, once the animal struggles, or neurological twitch occurs due to surgical stimulation, it will cause dissection failure. [0003] Special attention should be paid to the fact that the limbs of the fixed animals were stretched and opened outwards. However, in most experiments, the abdomin...

[0003] Special attention should be paid to the fact that the limbs of the fixed animals were stretched and opened outwards. However, in most experiments, the abdominal skin of the animals needs to be cut open. The separation of the lateral skin makes the torso and limbs expand horizontally. At this time, many fixed limbs cannot meet the expansion requirements. If the torso is not re-fixed, the torso will easily skew and cause internal organs to be squeezed and unclear.
