Device used for replacing experimental tools and guaranteeing positioning accuracy for stereotaxic apparatus conveniently and rapidly and application method of device

Abstract

The invention provides a device used for replacing experimental tools and guaranteeing the positioning accuracy for a stereotaxic apparatus conveniently and rapidly and an application method of the device. The device used for replacing the experimental tools and guaranteeing the positioning accuracy conveniently and rapidly comprises a stand column, a first driving shaft, a first driving sliding block, a connecting plate, a spindle head, a micro-syringe driving device and a guider, the first driving shaft and the guider are arranged at the two ends of the same side of the stand column respectively, the spindle head and the micro-syringe driving device are both fixedly arranged on the connecting plate, the connecting plate is fixedly connected with the first driving sliding block, and the first driving sliding block is arranged on the first driving shaft to slide. Through the spindle head adjustable in clamping range, clamping of the experimental tools of different types and different models is achieved. In addition, the guider, the spindle head and the micro-syringe driving device are used in a matched mode to guarantee the positioning accuracy of the experimental tools. The device solves the problem that in the traditional technology, a plurality of experimental clamping tools are needed, simplifies design of the clamping tools, and saves the troubles brought by the clamping tools, and meanwhile, the device is convenient to use, simple to operate and obvious in effect.

Description

technical field [0001] The invention relates to a device for conveniently replacing experimental tools and ensuring positioning accuracy, in particular to a device for conveniently replacing experimental tools and ensuring positioning accuracy during the use of a brain stereotaxic instrument, and belongs to the technical field of neurosurgery equipment. Background technique [0002] The animal brain stereotaxic instrument for scientific experiments is an important research equipment in the fields of neuroanatomy, neurophysiology, neuropharmacology and neurosurgery. In the establishment of animal models of Parkinson's disease, animal models of epilepsy, establishment of brain tumor models, learning and memory, neural stem cell transplantation in the brain, cerebral hypoxia, etc. [0003] Animal brain tissue experiments usually require precise completion of different experimental operations at the same site, such as directional puncture, injection, tissue extraction, etc. Dif...

AI Technical Summary

Problems solved by technology

In order to make the medical devices basically in the same stereotaxic position, the experimenters usually need to spend a long time to readjust the precise positions of different mechanical arms, which reduces the timeliness of brain tissue experiments, especially fresh brain tissue in vitro experiments, and affects the experimental results. credibility of the data

Generally, the needles of puncture needles and micro-injectors are elongated shafts with poor rigidity, which reduces the stability of the puncture or injection process

At present, there is almost no equipment to guide the puncture needle and microsyringe needle, and the needle will bend during the needle insertion process
