The number of patients is expected to continue to grow in the foreseeable future, remaining at a high level for a long time, placing a heavy burden on families and society. Treatment for central nervous system degenerative diseases typically involves medication, but long-term use of drugs can lead to reduced efficacy and side effects, and may even worsen disease symptoms.

[0003] In recent years, non-drug treatments have been attempted in clinical practice to improve disease symptoms, such as deep brain stimulation surgery, exercise therapy, and gene-targeted therapy for central nervous system diseases. However, these methods require craniotomy to implant the treatment device in the brain, which is complicated and expensive. Summary of the Invention

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0034] This application provides a human brain photostimulation device and system to address the problem that existing treatments for degenerative diseases of the central nervous system require craniotomy, which is cumbersome and expensive. The following description, in conjunction with the accompanying drawings, will illustrate this.

[0035] like Figure 1 As shown, this application provides a human brain photostimulation device. Figure 1 This is a schematic diagram of a human brain photostimulation device. This device can be applied to various degenerative diseases of the central nervous system. Taking Parkinson's disease patients as an example, this device emits near-infrared light deep into the patient's brain. Near-infrared light is an electromagnetic wave between visible and mid-infrared light. For example, near-infrared light with a wavelength of 670nm can activate photoreceptors such as cytochrome C oxidase, thereby regulating human metabolism. Therefore, near-infrared light can penetrate between various tissues in the body, passing through intracranial tissues and reaching deep into the brain. Near-infrared light reaching deep into the brain can stimulate the central nervous system, regulate the patient's metabolism, protect the central nervous system, and thus prevent the onset of Parkinson's symptoms, exhibiting a rapid and stable therapeutic effect.

[0036] like Figure 1-3 As shown, in some implementations, Figure 2 An explosion view of a human brain light stimulation device. Figure 3This is a schematic diagram of the implantation mechanism 2 in a human brain optical stimulation device. The human brain optical stimulation device includes a delivery mechanism 1 and an implantation mechanism 2. The delivery mechanism 1 includes a piston rod 11, a push rod 12, and a guide 13. The output end of the piston rod 11 is connected to the input end of the push rod 12. The guide 13 has a through hole in the middle, through which the output end of the push rod 12 passes. The implantation mechanism 2 includes a housing 21, a light source 22, a power supply 23, and a control module 24. The housing 21 has a cavity 211 inside. The control module 24... Both the light source 22 and the power supply 23 are connected to the inner wall of the cavity 211. The light source 22 is electrically connected to the control module 24. The output end of the power supply 23 is electrically connected to the light source 22 and the control module 24 respectively. One end of the outer shell 21 is detachably connected to the output end of the push rod 12, and the other end of the outer shell 21 is used to connect to the inner wall of the sphenoid sinus cavity. The maximum cross-sectional size of the implantation mechanism 2 is larger than the cross-sectional size of the through hole at the output end of the push rod 12. The light source 22 can emit near-infrared light towards the brain, and the near-infrared light can penetrate the intracranial tissue to reach the depths of the brain.

[0037] During patient treatment, a matching implantation device 2 can be designed based on the patient's symptoms and assembled onto the delivery mechanism 1. The implantation device 2 is then placed inside the patient's nose. Guided by the guide 13, the implantation device 2 is delivered into the patient's sphenoid sinus cavity via the piston rod 11 and push rod 12. Maintaining the position of the guide 13, the piston rod 11 is pulled back, causing the piston rod 11 to move the implantation device 2 outward via the push rod 12. Because the size of the implantation device 2 is larger than the through-hole, the output end of the guide 13 applies a reaction force to the implantation device 2, causing the push rod 12 to separate from the implantation device 2. Finally, the implantation device 2 falls into the patient's sphenoid sinus cavity, and the push rod 12 and guide 13 are removed. During operation, the control module 24 within the implantation device 2 controls the light source 22 to emit near-infrared light. This near-infrared light can penetrate intracranial tissue to reach deep into the brain and stimulate the central nervous system deep within the patient's brain, thereby treating the patient.

[0038] In this embodiment, the cavity 211 is used to house the various components of the device and provides protection for them. The outer shell 21 can be made of non-biodegradable polymers or alloys, such as polyurethane, stainless steel, titanium, etc. The outer shell 21 can also be a one-piece molded structure, with the head of the outer shell 21 designed as a cylinder with a diameter of 3mm, and a cylindrical handle installed at the tail of the outer shell 21. The bottom end of the cylindrical handle has a groove, and the output end of the push rod 12 is inserted into the groove. The power supply 23 uses a micro battery, which powers the control module 24 and the light source 22 through a micro power interface. The light source 22 uses a near-infrared light source with a diameter of 1mm, and the light source 22 can continuously emit near-infrared light in the wavelength range of 650–2500nm deep into the brain.

[0039] like Figure 1-6As shown, based on the above embodiments, this application preferably provides the following embodiments: Figure 4 This is a schematic diagram of the first type of implantable mechanism 2 in a human brain optical stimulation device. Figure 5 This is a schematic diagram of the second structure of the implantable mechanism 2 in the human brain optical stimulation device. Figure 6 This is a schematic diagram of the third structure of implantable mechanism 2 in a human brain photostimulation device.

[0040] In one embodiment, the outer shell 21 includes a light-transmitting shell 212, a gripper 213, and a spring 214. The cavity 211 is located inside the light-transmitting shell 212. The gripper 213 is connected to the outer wall of the light-transmitting shell 212 through the spring 214. The bottom end of the gripper 213 is inserted into the output end of the push rod 12, and part of the gripper 213 passes through the through hole of the guide member 13. A light source cover 221 is connected to the outer wall of the light source 22. The light source cover 221 is used to converge or diverge light. When the delivery mechanism 1 is assembled with the implantation mechanism 2, the gripper 213 is partially placed in the through hole of the guide 13. The gripper 213 will be squeezed by the inner wall of the through hole. At this time, the spring 214 is in a compressed state, and the gripper 213 on the light-transmitting shell 212 is in a contracted state. After the implantation mechanism 2 falls into the sphenoid sinus cavity, the spring 214 recovers its deformation, the gripper 213 is in an unfolded state in the sphenoid sinus cavity and adheres to the inner wall of the sphenoid sinus cavity. The control module 24 controls the light source 22 to emit near-infrared light. The near-infrared light can be transmitted from the light-transmitting shell 212 into the sphenoid sinus cavity and pass through the intracranial tissue to reach the depths of the brain.

[0041] In this embodiment, several grippers 213 can be used, and they are evenly distributed on the bottom sidewall of the light-transmitting housing 212. In specific implementation, the number of grippers 213 can be set to eight, and the eight grippers 213 are evenly installed on the bottom sidewall of the light-transmitting housing 212. The diameter of the patient's sphenoid sinus cavity is about 8 mm, and the diameter of the sphenoid sinus opening is about 5 mm. The cross-sectional size of the through hole at the output end of the push rod 12 can be set to 4.4 mm. When the grippers 213 are compressed, the cross-sectional size of the eight grippers 213 is set to 4.5 mm. When the grippers 213 are naturally unfolded, the cross-sectional size of the outer shell 21 formed by the eight grippers 213 is set to 8.2 mm to 8.4 mm. The light source cover 221 can fix the light source 22 and focus the light emitted by the light source 22 before it is emitted from the light-transmitting housing 212. The light source cover 221 can be made of a reflective metal or alloy, and the light-transmitting surface of the light source cover 221 can be processed into a mirror. Depending on the specific application scenario, the light source cover 221 can focus or disperse near-infrared light, thereby ensuring its transmission effect and performance. The housing 212 can be made of polymethyl methacrylate to ensure the transmission effect of the light source 22.

[0042] A camera and a signal transmitter / receiver can be embedded in the outer wall of the gripper 213. An angle adjuster is installed in the through hole at the output end of the guide 13. The camera is connected to the signal transmitter / receiver, which is connected to the control module 24 and an external terminal. The angle adjuster is connected to the control module. Before the implantation mechanism 2 falls, the angle adjuster can adjust the rotation angle of the implantation mechanism 2 so that the light source 22 is aligned with the depth of the brain. After the implantation mechanism 2 falls, the camera can collect the light information emitted by the light source 22 onto the wall of the sphenoid sinus cavity and transmit the collected light information to the external terminal through the signal transmitter / receiver. The external terminal can analyze the collected light information, determine that the light source 22 is aligned with the depth of the brain, and send a control command to the signal transmitter / receiver. The signal transmitter / receiver transmits the control command to the control module 24. The control module 24 controls the angle adjuster to adjust the contact position of the gripper 213 so that the light source 22 is aligned with the depth of the brain, which can improve the treatment effect. At the same time, the light source cover 221 can further focus the light emitted by the light source 22, so that the light can be more concentrated and penetrate into the depth of the brain, improving the treatment effect for the patient.

[0043] In addition, the clamps 213 can also adopt four C-shaped structures and be evenly surrounded on the bottom side wall of the light-transmitting shell 212. After the implantation mechanism 2 is delivered into the sphenoid sinus cavity, the doctor can push the implantation mechanism 2 out through the piston rod 11, so that each clamp 213 unfolds and abuts against the inner wall of the sphenoid sinus cavity; the outer surface of the clamps 213 can also be sanded to increase the friction between the clamps 213 and the inner wall of the sphenoid sinus cavity, thereby preventing the implantation mechanism 2 from shifting position.

[0044] like Figure 4-6 As shown, in this embodiment, the unfolding direction of the gripper 213 can be towards the light source 22, or towards the push rod 12, or towards other mounting directions. This application does not impose any restrictions on this.

[0045] like Figure 1-3 As shown, in one embodiment, the guide member 13 includes a hollow cylinder 131 and a flexible hose 132. The output end of the hollow cylinder 131 is connected to the input end of the flexible hose 132. Both the hollow cylinder 131 and the flexible hose 132 have through holes in the middle. The output end of the push rod 12 passes through the input end of the hollow cylinder 131 and exits sequentially through the through holes of the hollow cylinder 131 and the flexible hose 132. The output end of the flexible hose 132 has an opening, and a portion of the gripper 213 is placed in the opening. The outer wall of the gripper 213 has a protrusion that abuts against the inner wall of the opening. The outer wall of the output end of the piston rod 11 has a slot 111, and the outer wall of the input end of the push rod 12 has a locking block 121 that engages in the slot 111.

[0046] In use, the locking block 121 at the input end of the push rod 12 is engaged in the locking groove 111 on the outer wall of the output end of the piston rod 11. The output end of the push rod 12 is then passed through the through hole of the empty cylinder 131 and the through hole of the flexible tube 132 in sequence. The implantation mechanism 2 is then inserted into the output end of the push rod 12. The gripper 213 part of the implantation mechanism 2 is placed in the through hole of the flexible tube 132, so that the protrusion on the gripper 213 abuts against the inner wall of the opening. Then, guided by the empty cylinder 131 and the flexible tube 132, the push rod 12 is pushed out through the through hole of the piston rod 11. The output end of rod 12 and the implantation mechanism 2 are inserted into the patient's sphenoid sinus cavity. Then, the piston rod 11 is pulled back. Since the maximum cross-sectional size of the implantation mechanism 2 is smaller than the size of the opening, the implantation mechanism 2 will separate from the push rod 12 at the opening. Finally, the control module 24 controls the light source 22 to emit near-infrared light. The near-infrared light can penetrate the sphenoid sinus cavity wall and intracranial tissue and reach the depths of the brain. The near-infrared light can stimulate the central nervous system deep in the patient's brain, thereby achieving a therapeutic effect on the patient.

[0047] like Figure 1-3 As shown, in one embodiment, the outer shell 21 includes a light-transmitting shell 212, a gripper 213, and a telescopic rod. The cavity 211 is located inside the light-transmitting shell 212. The inner wall of the gripper 213 is connected to the outer wall of the light-transmitting shell 212 via the telescopic rod. The bottom end of the gripper 213 is inserted into the output end of the push rod 12. The telescopic rod is electrically connected to the control module 24. Part of the gripper 213 is inserted into the through hole of the guide member 13.

[0048] In this embodiment, the telescopic rod can be an electrically operated telescopic rod. Before the implantation mechanism 2 falls into the sphenoid sinus cavity, the electrically operated telescopic rod and the gripper 213 are in a retracted state and are installed at the output end of the push rod 12. After the implantation mechanism 2 falls into the sphenoid sinus cavity, the control module 24 controls the extension of the electrically operated telescopic rod according to the size of the patient's sphenoid sinus cavity. The electrically operated telescopic rod can cause the gripper 213 to unfold, so that the gripper 213 abuts against the inner wall of the patient's sphenoid sinus cavity, thereby preventing the implantation mechanism 2 from sliding in the patient's sphenoid sinus cavity.

[0049] like Figure 1 , 2 As shown in 3 and 7, Figure 7This is a structural block diagram of signal transmission of components in a human brain photostimulation system. This application also provides a human brain photostimulation system, including the human brain photostimulation device, camera 3, communication module 4, and host computer 5 as described above. The camera 3 can be connected to the outer wall of the gripper 213, and can acquire image information of the sphenoid sinus cavity. The communication module 4 is connected to the inner wall of the outer shell 21, and is electrically connected to the control module 24 and the camera 3. The communication module 4 can transmit the image information of the sphenoid sinus cavity to the outside. The host computer 5 is located outside the human brain and is wirelessly connected to the communication module 4. The host computer 5 can receive the image information of the sphenoid sinus cavity and provide feedback control commands based on the image information. After receiving the control commands sent by the host computer 5, the communication module 4 can transmit the control commands to the control module 24. The control module 24 can adjust the wavelength of the light source 22 in the human brain photostimulation device according to the commands. Different wavelengths of infrared light can provide appropriate treatment according to the different symptoms of the patient, thereby achieving the best treatment effect. The power supply 23 can provide power to the camera 3 and the communication module 4.

[0050] In this embodiment, the host computer 5 includes a processing module 51 and a display module 52. The processing module 51 is wirelessly connected to the communication module 4, and the communication module 4 is electrically connected to the display module 52.

[0051] In use, the locking block 121 at the input end of the push rod 12 is engaged in the locking groove 111 on the outer wall of the output end of the piston rod 11. The output end of the push rod 12 is then passed through the through hole of the empty cylinder 131 and the through hole of the flexible tube 132 in sequence. The implantation mechanism 2 is then inserted into the output end of the push rod 12. The clamp 213 part of the implantation mechanism 2 is inserted into the through hole of the flexible tube 132, so that the protrusion on the clamp 213 abuts against the inner wall of the opening. Then, guided by the empty cylinder 131 and the flexible tube 132, the output end of the push rod 12 and the implantation mechanism 2 are inserted into the patient's sphenoid sinus cavity. After that, the piston rod 11 is pulled back. Since the maximum cross-sectional size of the implantation mechanism 2 is smaller than the size of the opening, the implantation mechanism 2 will separate from the push rod 12 at the opening. Finally, the control module 24 controls the light source 22 to emit near-infrared light. The near-infrared light can penetrate the intracranial tissue to reach the depths of the brain and stimulate the central nervous system deep in the patient's brain, thereby treating the patient. During operation, camera 3 can acquire real-time image information of the patient's sphenoid sinus cavity. This image information can be transmitted to an external host computer 5 via communication module 4. The processing module 51 in the host computer 5 can analyze the received image information. After analysis, the processing module 51 can wirelessly transmit control commands to the communication module 4 in the implantation device 2. The communication module 4 transmits the control commands to the control module 24, which adjusts the human brain light stimulation device appropriately, thereby improving the patient's treatment effect. At the same time, the image information acquired by camera 3 can also be wirelessly transmitted to the display module 52 in the host computer 5 via communication module 4, thus facilitating the doctor's diagnosis.
