Stereotactic fixing frame for hillock hemorrhage biological experiment

Abstract

A three-dimensional positioning fixing frame for a hillock hemorrhage biological experiment effectively solves the problem that a mouse absorbs medicine slowly after the mouse is injected with the medicine and comprises a box body, a bottom plate is fixedly connected to the interior of the box body, a rotating shell is arranged on the upper side of the bottom plate, an operation plate is arranged in the rotating shell, and a power rod is arranged on the upper side of the bottom plate. A rotating frame is arranged on the lower side of the power rod, a driving plate is arranged on the left side of the rotating frame, a first runway cavity is formed in the left side of a rotating shell, a second runway cavity is formed in the right side of the rotating shell, a cover plate is arranged on the upper side of the rotating shell, first fixing plates are fixedly connected to the front side and the rear side of the rotating shell, and second fixing plates are arranged on the front side and the rear side of the rotating shell. By means of the design, the function of driving an experimental mouse to move so as to accelerate blood circulation is effectively added, the purposes of fixing the mouse and conducting intravenous injection on the tail are achieved, and the problem that an experimental site is not easy to clean after an experiment is conducted is solved.

Description

technical field [0001] The invention belongs to the technical field of medical experimental equipment, and in particular relates to a stereotaxic fixing frame for biological experiments of thalamic hemorrhage. Background technique [0002] The thalamus, also known as the dorsal thalamus, is the largest oval gray matter nucleus in the diencephalon. It is located on both sides of the third ventricle. The left and right thalamus are connected by a gray matter mass (called the middle block). The thalamus is the high-level sensory center. It is the most important sensory conduction relay station. In clinical medicine, the influence of different drugs on the thalamus is a very important topic. In academic research, mice are usually used as experimental samples, and usually pre-venously administered to mice. Injection, and then create a mouse thalamic hemorrhage, dissect the mouse and study and analyze the specific cells or tissues in the brain, but because of the experimental proc...

Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a stereotaxic fixed frame for biological experiments of thalamic hemorrhage, which effectively solves the problem that the mice absorb the medicine slowly after injecting the medicine to the mice, and increases the driving force. The function of exercising mice to speed up blood circulation in the experiment has achieved the purpose of immobilizing the mice and performing tail vein injection, achieving the purpose of automatically raising the surgical instruments when the mice need to be operated, and optimizing the The fixing method of the mouse torso optimizes the fixing structure of the mouse head, which is convenient for the medical staff to take the surgical instruments, solves the problem that the experimental place is not easy to clean up after the experiment, and adds the ability to disinfect the device function to facilitate the discharge of sewage
