Background
Fluorescence imaging with free movement of animals is an important means for neurobehavioral decoding in brain science. The method needs to use a micro microscope system which needs to be connected with micro equipment and a computer which are adsorbed on the animal through a very thin and soft coaxial radio frequency wire, and a biological fluorescent signal acquired from the freely moving animal is transmitted to the computer at a high speed under the condition that the weight of the attached equipment is not obviously increased.

All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example 1
The coaxial radio frequency connecting wire of the miniature microscope can transmit the biological signals of the living animal body to a computer connected with the coaxial radio frequency connecting wire at a high speed, and the coaxial wire is required to be extremely thin and soft, so that the weight of the miniature microscope can be reduced to the maximum extent, the pressure on the small animal moving freely is reduced, and meanwhile, the radio frequency wire is extremely soft and does not block the free behavior of the animal. But such thin rf wires are extremely prone to entanglement and deformation damage. The invention is supposed to wrap the radio frequency connecting wire of the micro microscope through the light and soft capillary (such as PE polyethylene pipe) to play the role of softness and resistance to winding deformation damage.
Therefore, in view of the above disadvantages, the present invention proposes to use a lightweight and flexible capillary (such as a PE polyethylene tube) to wrap the rf connection line of the micro-microscope, so as to achieve the effects of flexibility and resistance to winding deformation and damage.
The technology of the invention comprises the following basic contents: the light and soft capillary tube (such as a PE polyethylene tube) wraps the radio frequency connecting wire of the micro microscope, so that the connecting wire is soft and is resistant to winding deformation and damage.
The technical scheme of the invention is elaborated as follows:
the invention mainly uses a light and soft capillary tube (such as a PE polyethylene tube) to wrap the radio frequency connecting wire of the micro microscope, thereby realizing the effects of softness, winding deformation and damage resistance of the connecting wire.
The method comprises the following specific steps:
1. referring to FIG. 1, a high frequency coaxial wire (50 ohm high frequency coaxial wire as listed in this scenario: A9438W-10-ND, CW2040-3650SR,538-50 MCX-37) suitable for connection to micro devices has a diameter of about 0.5 mm and a length of about 1 meter (typically 0.5-1.5 meters).
2. Referring to fig. 1, a light and flexible capillary tube (e.g., PE polyethylene tube) is selected from PE50 in the present embodiment, which has an outer diameter of 0.96 mm, an inner diameter of 0.58 mm, and a length of 0.8 m.
3. After the high frequency coaxial wire has passed through the capillary, the polyethylene capillary is coated 502 at the end of the capillary so that the wire is secured at both ends of the tube.
4. And an interface for connecting the SMA connector in the instrument with the miniature imaging instrument.
The upper diagram (left, middle and right) of fig. 2 is the deformation of the high-frequency coaxial wire of the micro microscope after spontaneous curling at rest, free behavior, and disentanglement, and it can be seen that the wire is easy to tangle and deform at various stages before modification, and in animal experiments, it usually takes much time to disentangle such compact tanglement and easily damages the imaging system.
The lower drawing (left, middle and right) of fig. 2 shows the modified high frequency coaxial wire of the microscope, which is wound after standing and free action, and can be unwound by directly stretching both ends after winding. Therefore, the coaxial connecting scheme is flexible, winding-resistant and not prone to damage, stability of the imaging system can be obviously improved, and time of experimenters can be saved.
The key points and points to be protected of the invention are as follows:
the imaging system is based on the scheme for realizing the connection of the flexible anti-winding coaxial line.
The invention has the following advantages:
the connecting wire that this scheme realized is soft antiwind, is difficult to damage, can reduce the system fault rate and practice thrift the experimenter and remove the time of tangle and the risk of damaging the system.
The invention can realize the final purpose of the invention through practical verification.
