Background
Marmoset is a small-sized primate, and the volume of the marmoset is slightly larger than that of a rat. However, unlike the conventional rodent experimental animals, there are significant individual differences in body size, skull shape, and nucleus location among different marmosets. Considering that the deep brain nuclei of marmosets are themselves small, accurate localization of deep brain nuclei of marmosets (e.g. for virus or drug injection surgery) must be combined with MRI imaging methods.
In the in-vivo skull surgery and MRI imaging of the marmosets, the heads of the marmosets are required to be ensured to be completely free from movement in the surgery and imaging processes so as to realize accurate positioning. This requires a suitable marmoset orientation apparatus to achieve accurate fixation of the marmoset head during surgery and imaging. This positioning apparatus needs to satisfy the following requirements: (1) the head of the marmoset monkey can be strictly fixed, and the fixation can bear the pressure caused by surgical operation and autonomous movement of animals (because of unstable anesthesia); (2) the fixation of the locator can be adjusted correspondingly along with the change of the body type of the marmoset; (3) nuclear magnetic compatibility, and the locator is small enough to be placed in an MRI instrument; (4) the locator can be well linked and matched with a gas anesthesia system.
