Abstract

A multifunctional head fixation instrument for murine head and neck operations is characterized by comprising a base, a column, a slider, a cross rod, a press rod, a vertical shaft and a temperature control system. The column is fixed in the middle of the left end of the upper surface of the base vertically, a rectangular groove is formed on the right side of the column, a rectangular through hole which extends along left and right and corresponds to the rectangular groove is formed in the lower half portion of the column, and a rectangular groove corresponding to the rectangular groove is arranged at the left end of the slider. The multifunctional head fixation instrument is easy and convenient to operate, low in manufacturing cost and small in space occupation and capable of fixing rat heads by cooperation of the cross rod and the press rod; all-side rotation of the rat heads is achieved by rotating the cross rod so that the instrument has full-side operational angle; body temperature of rats in anesthetic states is maintained by means of the temperature control system so that long-time operation can be achieved; operational visual field can be enlarged by a view enlarging system so that operational precision can be improved; components of the instrument are convenient to change due to the bolt connection structures arranged at multiple positions.

Description

technical field [0001] The invention relates to a mouse head fixation device, in particular to a multifunctional head fixation instrument for head and neck surgery of mice. Background technique [0002] In the field of neuroscience research, in order to better study the functions and functions of various nerve nuclei in the rat or mouse brain, researchers need to fix the head of the rat or mouse firmly, along the midline Cut the skin at the top of the head longitudinally, and locate the inner brain mass by relying on the bony sutures of the skull to mark the bregma, bregma, and midline. A small amount of medicine is injected into the nucleus through the method of intracerebral microinjection. Such an experimental method needs to firmly fix the snouts and ears of rats and mice, so researchers have invented a stereotaxic instrument for rats and mice, for example, the famous Japanese Chengmo ( Narishige Group) SR-6R (rat double arms) brain stereotaxic instrument. The rat bra...
