Description

Technical Field

[0001] The invention relates to the technical field of experimental equipment, and in particular to an automated precise control system for small animal intracranial implantation surgery. Background Art

[0002] In small animal intracranial implantation surgery, precise positioning and control of implants are crucial, especially for the implantation of electrodes or microprobes in neuroscience research. Traditional methods are usually manual operations, with the implantation depth and speed adjusted by mechanical devices or manually. However, manual control has significant limitations, including insufficient accuracy, poor repeatability, and difficulty in achieving stable advancement at extremely low speeds (such as micrometers / second). Especially when slow implantation is required to avoid blocking damage and reduce minimally invasive interference during the implantation process, manual operation can hardly meet these requirements.

[0003] In the existing technology, the control of implantation speed is still mainly based on manual operation. Although some studies have achieved the stability of advancement depth through mechanical devices, most of them have not independently optimized the implantation speed, which is especially insufficient for implantation in deep brain areas. Slow implantation is crucial to reducing brain tissue stress and avoiding cell damage, but it is difficult to control the implantation speed in the existing technology, which cannot meet the needs of slow and precise advancement.

[0004] In view of this, the present invention provides a slow implantation device in the animal brain capable of controlling precise advancement and speed. Summary of the invention

[0022] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0023] Please refer to Figure 1 The present invention proposes an automated precision control system for intracranial implant surgery of small animals, comprising a speed controller 3, a time controller 2 and a stepper motor controller 1, wherein:

[0024] The stepper motor controller 1 is electrically connected to the speed controller 3 and the time controller 2 respectively. The stepper motor controller 1 is connected to a stepper motor 4. The output end of the stepper motor 4 is connected to an implant device. The implant device includes a screw connected to the output end of the stepper motor 4, a fixed bracket 6 connected to the stepper motor 4, a slide rail 11 connected to one side of the fixed bracket 6, and a slider 12 arranged on the slide rail 11 and the screw. A clamping arm 13 is arranged on the slider 12. The motor drives the screw to rotate and causes the slider 12 to drive the clamping arm 13 to clamp the implant and move it.

[0025] In a specific embodiment, the stepper motor 4 serves as the power source of the entire device, and drives the clamping arm 13 to move the implant up and down through the screw drive. The fixed bracket 6 connects the stepper motor 4 and the slide rail 11 to provide mechanical support. The speed controller 3 and the time controller 2 send instructions to the stepper motor controller 1 to achieve precise control of the stepper motor 4. The stepper motor 4 drives the screw to rotate, and further drives the slider 12 to slide up and down on the slide rod. The slider 12 drives the clamping arm 13 to move while moving, and enables the clamping arm 13 to clamp the implant and implant it into the brain of the small animal. The present application controls the clamping arm 13 through the speed controller 3 and the time controller 2 to ensure the accuracy and controllability of the implantation speed and depth, achieve micron-level precision movement, and effectively reduce the risk of brain tissue damage.

[0026] In one embodiment, a servo motor can be used to replace the stepper motor 4, and the higher dynamic responsiveness and stability of the servo motor can be used to further improve the precise control of the implantation process. A multi-degree-of-freedom robotic arm can also be added to achieve accurate implantation at multiple angles based on vertical slow motion to accommodate more complex brain area targets.

[0027] Furthermore, the implant device also includes a connecting ring 7, and the output end of the stepper motor 4 is connected to the screw rod through the connecting ring 7.

[0028] In a specific embodiment, the connecting ring 7 is used to connect the screw rod and the stepping motor 4 , and the output torque of the stepping motor 4 is transmitted to the screw rod through the connecting ring 7 .

[0029] Furthermore, the implantation device also includes a magnetic grating reader 8 and a magnetic stripe 9 . The two sides of the magnetic stripe 9 are respectively on the two sides of the slide rail 11 , and the magnetic grating reader 8 is fixed on the slide 12 .

[0030] In a specific embodiment, the magnetic grating reader 8 senses the relative displacement as the slider 12 moves, collects the displacement data of the slider 12 in real time and displays it on the displacement display 10, further ensuring the accuracy and controllability of the implantation process.

[0031] In one embodiment, a laser displacement sensor may be used to replace the magnetic grating reader 8 and the magnetic strip 9 to accurately display the distance moved by the slider 12 .

[0032] Furthermore, the implant device also includes a displacement indicator 10 , which is electrically connected to the magnetic grating reader 8 .

[0033] In a specific embodiment, the displacement display 10 is used to display the moving distance of the slider 12 in real time, providing data support for the precise control of the implantation depth, and facilitating further control of the implantation depth.

[0034] Furthermore, a manual controller is also included. The manual controller is electrically connected to the stepper motor controller 1 , and the manual controller is used to control the start, stop and rotation direction of the stepper motor 4 .

[0035] In a specific embodiment, two function keys are provided on the manual controller, the function key on the left is used to start and stop the operation of the stepper motor 4, and the function key on the right is used to control the rotation direction of the stepper motor 4, thereby realizing the up and down movement of the clamping arm 13.

[0036] Furthermore, the time controller 2 is used to set the operating time.

[0037] In a specific implementation, the time controller 2 is connected to the stepper motor controller 1 to control the stopping and starting of the device. The time controller 2 has a countdown function and can stop working after the system automatically runs for a set time, thereby simplifying the operation process and improving efficiency.

[0038] Furthermore, the speed controller 3 is used to send a pulse signal of a set frequency and accurately control the rotation speed of the stepper motor 4 .

[0039] In a specific embodiment, the speed controller 3 sends a pulse signal of a set frequency to the stepper motor controller 1 to accurately control the rotation speed of the stepper motor 4, thereby adjusting the moving speed of the slider 12 to achieve slow and stable implantation.

[0040] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
