Mouse neurosurgery bed

Abstract

The invention discloses a mouse neurosurgery bed which comprises a body fixing platform, an adjusting device and a head fixing device. The heat fixing device is fixed at the front end of the body fixing platform through the adjusting device, the body fixing platform fixes the body of a mouse, and the head fixing device fixes the head of the mouse; the adjusting device comprises an upward-downwardmoving plate and a leftward-rightward moving plate, the leftward-rightward moving plate is arranged on the front end face of the body fixing platform in a manner of being capable of sliding leftwardsand rightwards, the upward-downward moving plate is arranged on the front end face of the leftward-rightward moving plate in a manner of being capable of sliding upwards and downwards, and two inserting holes are formed in the front end face of the upward-downward moving plate; the head fixing device comprises a fixing ring, a nose clamp and two bitamporal fixing rods, the nose clamp and the bitamporal fixing rods are arranged on the fixing ring, the fixing ring is provided with an opening, and inserting pins are symmetrically fixed at two open ends of the fixing ring and correspondingly inserted in the two inserting holes. Through the above mode, the mouse neurosurgery bed can fix body position of the mouse comfortably, so that the mouse can well cooperate with neurosurgery operation to complete surgery smoothly.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a mouse neurosurgery operating bed. Background technique [0002] With the continuous deepening of basic neuroscience research, mouse neurosurgery such as mouse craniotomy or drilling stereotaxic injection has become a basic experimental skill that workers engaged in basic neuroscience research need to master. Because most of these operations are microscopic and delicate operations, the head of the mouse needs to be absolutely immobilized during the operation. However, due to the small size of the mouse skull, it is difficult to fix the head. [0003] At present, when performing neurosurgery on mice, the brain stereotaxic instrument is mainly used to fix the head of the mouse. During the whole operation, the head of the mouse is tightly fixed, and the body lies on the table without heat preservation device. , the head keeps tilting back. Although the brain stereotaxic instrum...

AI Technical Summary

Problems solved by technology

Although the brain stereotaxic instrument can effectively fix the head of the mouse and has a three-dimensional coordinate system, it does not consider how to make the mouse more comfortable to cooperate with the operation from the perspective of comfort, and often the mouse is precisely because of this Uncomfortable special positions lead to restlessness and struggle during the operation, which eventually lead to the failure of the operation

In addition, the mouse's head is generally fixed by ear sticks, but this fixation method easily damages the mouse's tympanic membrane and causes hearing loss in the mouse. This result is disastrous for experiments on hearing

It has been found through research that once the mice struggle during the operation, it is almost impossible to perform the operation under relatively light anesthesia, so it is necessary to continuously add anesthetics, which will easily lead to excessive use of anesthetics and cause damage to the functions of the important organs of the mice. impact; the mice will die during the operation due to the severe distortion of the body position, which leads to the obstruction of the blood circulation in the large blood vessels and the head; the above two are caused by the mice being fixed in an uncomfortable position; The body is kept warm, which can easily induce hypothermia and lead to serious postoperative complications
