Description

Technical Field

[0001] This invention relates to the field of experimental equipment technology, and in particular to a multi-fiber implantation device. Background Technology

[0002] Fiber optic implantation technology is one of the important experimental techniques in rodent neuroscience research. By implanting fiber optic conduits, fiber optic sleeves, or fiber optic probes into specific anatomical regions of the animal's brain and connecting them to lasers, photodetectors, or other optical devices through fiber optic connections located on the outside of the animal's head, optical stimulation, optical recording, or fluorescence signal acquisition of specific neural circuits can be achieved.

[0003] In single-fiber experiments, a single fiber optic sleeve or a fixed fiber optic base can usually be used to fix the implanted fiber. However, when the experiment requires simultaneous optical stimulation or recording of multiple brain regions, multiple fibers need to be implanted in the same animal's head. Due to the significant differences in the anatomical location of different regions of the rodent brain, multiple fibers often need to have different: anterior-posterior position; lateral position; spacing between fibers; implantation angle; and direction of the fiber relative to the skull surface. Therefore, multi-fiber implantation not only requires that each fiber can be fixed separately, but also that the fibers can form a spatial configuration suitable for the target brain region. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a multi-fiber implantation device.

[0005] This invention is achieved through the following technical solution: This invention proposes a multi-fiber implantation device comprising a central connector and a support arm, wherein: The bottom of the central connecting part is connected to a plurality of the support arms. One end of the support arm is connected to the central connecting part, and the other end is connected to the optical fiber fixing part. An optical fiber is fixed inside the optical fiber fixing part. The optical fiber fixing part can be rotated around the central connecting part and moved in the radial direction by the support arm, thereby changing the distance and position of the optical fiber fixing part.

[0006] Furthermore, a fiber optic fixing hole is provided on one side of the support arm, and the fiber optic fixing part is disposed in the fiber optic fixing hole.

[0007] Furthermore, the support arm has a connector and an adjustment part, the connector being used to connect the adjustment part and the optical fiber fixing part.

[0008] Furthermore, the support arm is provided with a sliding groove. When the connector is loosened, the optical fiber fixing part can move in the direction of the sliding groove through the adjusting part, and move the position of the optical fiber relative to the central connecting part.

[0009] Furthermore, a central locking component is provided on the central connecting part, which is used to adjust the tightness of the connection between the support arm and the central connecting part.

[0010] Furthermore, it also includes a central connecting post, which is disposed at the top of the central connecting portion.

[0011] The beneficial effects of this invention are: The multi-fiber implantation device proposed in this invention utilizes a central connecting part to connect multiple support arms. Each support arm is equipped with a fiber fixing part, and the fiber is fixed on the fiber fixing part. The fiber fixing part can rotate relative to the central connecting part and change its radial position. The multi-fiber implantation device can be adapted to different implantation trajectories in different brain regions. For different experimental schemes, traditional fixation structures require the fabrication of new support arms, while the fiber implantation device proposed in this invention can be reused. In traditional structures, each fiber is fixed individually, requiring the formation of multiple independent fixation structures on the surface of the animal skull, which is a relatively cumbersome operation. The device of this invention is a whole, which is more stable. Attached Figure Description

Detailed Implementation

[0014] Please refer to Figure 1 The present invention proposes a multi-fiber implantation device comprising a central connecting part 3 and a support arm 5, wherein: Multiple support arms 5 are connected to the bottom of the central connection part 3. One end of the support arm 5 is connected to the central connection part 3, and the other end is connected to the optical fiber fixing part 8. An optical fiber 4 is fixed inside the optical fiber fixing part 8. The optical fiber fixing part 8 can rotate around the central connection part 3 and move in the radial direction through the support arm 5, and change the distance and position of the optical fiber fixing part 8.

[0015] Specifically, the central connecting part 3 connects to multiple support arms 5, which can rotate around the central connecting part 3. Each support arm 5 is equipped with a fiber optic fixing part 8, which can move on the support arm 5. The fiber optic fixing part 8 fixes the fiber optic 4 inside the fiber optic fixing part 8. Through the support arms 5 and the fiber optic fixing part 8, the fiber optic 4 can move in the radial direction and change its angle. The number of support arms 5 can be set according to needs. Using multiple support arms 5 to adjust the position of the fiber optic 4 can achieve different implantation trajectories in different brain regions. Compared with traditional stents, it is more convenient to adjust and can be reused. At the same time, the entire fiber optic implantation device is an integral structure, which is more stable and simpler to operate.

[0016] Furthermore, a fiber optic fixing hole 4 is provided on one side of the support arm 5, and the fiber optic fixing part 8 is disposed in the fiber optic fixing hole 4.

[0017] Specifically, the end of the support arm 5 is provided with a fiber optic 4 fixing hole, and the fiber optic fixing part 8 is disposed in the fiber optic 4 fixing hole. The fiber optic fixing part 8 is rotated by the support arm 5.

[0018] Furthermore, the support arm 5 has a connector 6 and an adjustment part 7, the connector 6 being used to connect the adjustment part 7 and the fiber optic fixing part 8.

[0019] Specifically, the adjustment part 7 is cylindrical in shape, and the adjustment part 7 is provided with a fixing hole for the optical fiber 4. The optical fiber fixing part 8 is located inside the fixing hole for the optical fiber 4. The connector 6 is located at the bottom of the adjustment part 7, and the connector 6 is fixed to the adjustment part 7 and fixes the optical fiber fixing part 8 to the support arm 5.

[0020] Furthermore, a sliding groove is provided on the support arm 5. When the connector 6 is loosened, the fiber fixing part 8 can move in the sliding groove direction through the adjustment part 7 and move the position of the fiber 4 relative to the central connecting part 3.

[0021] Specifically, when connector 6 is loosened, the adjusting member can slide on the support arm 5, and the fiber fixing part 8 changes its radial position in the central connecting part 3 as the adjusting member changes, thereby further changing the position of the fiber 4.

[0022] Furthermore, a central locking element 2 is provided on the central connecting part 3, which is used to adjust the tightness of the connection between the support arm 5 and the central connecting part 3.

[0023] Specifically, when the central locking element 2 is released, the support arm 5 can rotate around the central locking element 2 to change the relative angle of the optical fiber 4.

[0024] Furthermore, it also includes a central connecting post 1, which is disposed at the top of the central connecting part 3.

[0025] Specifically, the central connecting column 1 is used to connect the stereo positioning instrument holder.
