The invention provides a device for fixing the head of a
laboratory mouse and exposing the
oral cavity of the
laboratory mouse, relates to the technical field of special appliances for the
laboratory mouse, and solves the limitation problems that an existing device is poor in adaptability, insufficient in
exposure and easy to slip, needs extra manpower and the like. When a mouse lies on the operation bottom plate of the device, the
upper tooth drag hook hooks the upper jaw
incisor of the mouse, the
cheek drag hook hooks the
left cheek and the
right cheek of the mouse, and the
lower tooth drag hook hooks the lower jaw
incisor of the mouse, so that the head of the mouse is fixed, and the
oral cavity of the mouse is exposed; the sides, far away from the head of the mouse, of the
upper tooth drag hook and the
cheek drag hook are correspondingly and detachably connected to the bottom plate fixing piece in the corresponding direction on the operation bottom plate; one side, far away from the head of the mouse, of the
lower tooth drag hook passes through the upper part of the body of the mouse and then is detachably connected to the bottom plate fixing piece in the corresponding direction on the operation bottom plate. According to the invention, only one experimenter is needed to stably fix the head of the mouse and
expose the
oral cavity, and no assistant is needed in the subsequent experiment process.
