Embodiment 1

[0047] Specific steps are as follows:

[0048] 1. Select 15 adult healthy carp with a body length (from the snout to the last scale of the trunk) of 33.12±1.62cm and a weight of 0.97±0.11kg.

[0049] 2. Place the carp in a solution of 0.36g / L eugenol for drug bath anesthesia, take it out and lay it flat on gauze, wipe off the water stains on the carp body, and fix it in a special fixing tank.

[0050] 3. Combine figure 1 and figure 2 As shown, carp draws a trace on the first fish scale (junction between head and torso), and sets its position as the origin of the space coordinate system, denoted as O.

[0051] 4. If image 3 As shown, after establishing the spatial coordinate system based on carp bony landmarks to determine the origin O, the Y-axis is defined as the line between the midpoint of the line between the two eyes on the surface of the skull and the origin O, and the positive direction points to the snout; The straight line at the coronal suture is defined as the...

Abstract

The invention discloses a carp brain electrode implantation method by means of magnetic resonance positioning and navigation. Taking the first fish scale (the junction of the head and the trunk) as the origin, reference scratches are made on the surface of the skull based on the characteristics of the carp skull to establish Space coordinate system; with the help of the T2WI fast spin echo scanning sequence of the magnetic resonance equipment, the brain is scanned and imaged, the two-dimensional coordinates of the electrode stimulation site are converted into three-dimensional space coordinates, and the spatial coordinates of the brain stimulation electrode implantation site are determined The coordinate value of the system; according to the coordinate value, the brain stimulation electrode is implanted for positioning and navigation. The invention can not only locate and navigate for the implantation of the carp aquatic animal robot brain stimulation electrodes, but also provide new positioning and navigation means for the implantation of various animal robot brain stimulation electrodes.

Description

technical field [0001] The invention relates to the field of biological control, in particular to a method for establishing a spatial coordinate system based on carp skull characteristics, determining the coordinates of carp brain stimulation electrode implantation sites by means of magnetic resonance scanning, and navigating for the implantation of brain stimulation electrodes. Background technique [0002] Animal robots have become an emerging cutting-edge high-tech field in the world today because of their flexibility and concealment. Animal robots have potential broad application prospects in the fields of ecological environment research, emergency rescue and disaster relief, military defense, industrial applications and medicine. As early as the last century, the research on animal robots began internationally, such as Japanese praying mantis robots, goldfish robots, American rat robots, monkey robots, shark robots, and Russian turtle robots, all of which can basically ...
