DETAILED DESCRIPTION

[0055] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] In the laboratory / operating room, during the operation of placing specific implants in the brain of an organism or administering specific drugs, in addition to the currently used manual implantation, other positioning devices are also used. However, there are some problems with the current positioning devices, including low implantation accuracy, too fast needle extraction speed, uneven dripping, and inability to observe the implantation position in real time. These problems make the operation complicated and require many steps. Among them, the operation of the implantation device requires high precision, and the experimenter needs to do it many times during the experiment, which can easily lead to operational errors and is more dependent on the experimenter's experience, thus affecting the success rate of the experiment.

[0057] like Figure 1 As shown, Figure 1 A top view of an electrode wire 01 implantation device provided by an embodiment of the present invention; In a first aspect, an electrode wire 01 implantation device provided by an embodiment of the present invention is used to implant the electrode wire 01 into the brain A of a living body, comprising:

[0058] The implantation mechanism 10 includes an implantation needle 11, a moving part 12 and a power assembly 13. The moving part 12 is connected to a fixed end 131 of the power assembly 13. The moving end 132 of the power assembly 13 is connected to a first end of the implantation needle 11 and is used to drive the implantation needle 11 to move in a first direction so that the implantation needle 11 approaches or moves away from the power assembly 13. The implantation needle 11 has a first state and a second state relative to the power assembly 13. When the implantation needle 11 is in the first state, the implantation needle 11 moves away from the power assembly 13, and the second end of the implantation needle 11 is used to form a physical connection with the electrode wire 01; when the implantation needle 11 is in the second state, the implantation needle 11 approaches the power assembly 13, and the second end of the implantation needle 11 is separated from the electrode wire 01.

[0059] A driving mechanism 20, connected to the moving part 12 of the implanting mechanism 10, for driving the implanting mechanism 10 to move along a first direction, so as to implant the electrode wire 01 physically connected to the second end of the implanting needle 11 and the implanting needle 11 together into a target area of ​​the brain of the organism;

[0060] A camera module 30, used to obtain image information of a target area;

[0061] The liquid supply mechanism 40 is used to uniformly provide continuous liquid to the electrode wire 01 or the implantation needle 11 after the electrode wire 01 physically connected to the second end of the implantation needle 11 and the implantation needle 11 are implanted together into the target area of ​​the brain of the organism.

[0062] It should be noted that in the above technical solution, the electrode wire 01 implantation device provided by the present invention includes an implantation mechanism 10, a driving mechanism 20, a camera module 30 and a liquid supply mechanism 40, wherein the implantation mechanism 10 includes an implantation needle 11, a moving part 12 and a power assembly 13, the driving mechanism 20 is connected to the moving part 12 of the implantation mechanism 10, the driving mechanism 20 drives the implantation mechanism 10 to move in a first direction, at this time, the implantation needle 11 is first driven to move to a first state through the power assembly 13, the first end of the implantation needle 11 is connected to the moving end 132 of the power assembly 13, the implantation needle 11 is driven to reciprocate along with the reciprocating motion of the moving end 132 of the power assembly 13, at this time, the electrode wire 01 to be implanted in the brain of the organism is physically connected to the second end of the implantation needle 11, and when the electrode wire 01 and the implantation are completed After the needle 11 is connected, the implantation mechanism 10 is moved as a whole toward the target area of ​​the brain A of the organism through the action of the driving mechanism 20, so that the electrode wire 01 physically connected to the implantation needle 11 is implanted into the target area of ​​the brain of the organism. At this point, the implantation of the electrode wire 01 is completed. When the electrode wire 01 and the implantation needle 11 are implanted into the target area of ​​the brain of the organism, the liquid supply mechanism 40 works to uniformly and continuously provide liquid to the electrode wire 01 or the implantation needle 11, so that the space between the electrode wire 01 and the implantation needle 11 is filled with liquid, reducing the friction between the electrode wire 01 and the implantation needle 11 to maintain stability during the separation process of the electrode wire 01 and the implantation needle 11, and separating the electrode wire 01 and the implantation needle 11 in a simple manner to facilitate the subsequent extraction of the implantation needle 11 from the brain of the organism. After the implantation of the electrode wire 01 is completed, the power assembly 13 works to drive the implantation needle 11 to move along the first direction to the second state, that is, the implantation needle 11 moves toward the fixed end 131 of the power assembly 13. The implantation needle 11 and the electrode wire 01 are separated due to the action of the liquid supply mechanism 40. At this time, the implantation needle 11 will be completely withdrawn from the brain of the organism. Through the automated action of the power assembly 13, the speed of the entire implantation needle 11 withdrawal process can be ensured to be uniform, and the speed is uniform and the size is controllable compared to manual withdrawal. In addition, with the cooperation of the liquid supply mechanism 40 for continuous and uniform liquid supply, it can be ensured that the space between the implantation needle 11 and the electrode wire 01 is completely filled with liquid, thereby ensuring that the friction between the implantation needle 11 and the electrode wire 01 is basically the same at various locations, thereby ensuring the accuracy of the position of the electrode wire 01 in the brain of the organism. At this point, the implantation of the electrode wire 01 after the implantation needle 11 is withdrawn is completed. In order to ensure the accuracy and success rate of the entire operation process, the above operation process will be observed and positioned in real time on the target area of ​​the brain A of the organism through the camera module 30.

[0063] For the positional relationship between the implant needle 11 and the electrode wire 01, refer to Figure 2 and Figure 3 , Figure 2A schematic diagram of the positional relationship between the electrode wire 01 and the implant needle 11 at a first angle provided by an embodiment of the present invention; Figure 3 A schematic diagram of the positional relationship between the electrode wire 01 and the implant needle 11 at a second angle provided by an embodiment of the present invention; Figure 2 In the embodiment, the electrode wire 01 is a part of the implant consumable 1, the electrode wire 01 and the implant needle 11 are stacked up and down along the second direction, and the first end 111 of the implant needle has a mounting hole 113, and the same is referred to Figure 4 The mounting hole 113 is fixed to the fixed boss 151 of the displacement block 15. The implant consumable 1 includes an electrode wire 01, an electrode interface 02 and a circuit board 03. The electrode interface 02 is set at the end of the circuit board 03 away from the electrode wire 01. For example, the circuit board can be a PCB (Printed Circuit Board) or an FPC (Flexible Printed Circuit). The implant consumable 1 can be adapted to different experimental animals, such as mice, rats, etc. The implant consumable 1 is set on the bracket 16 to complete the fixation of the implant consumable 1. The bracket 16 can be injection molded with PEEK (polyetheretherketone). The shape of the bracket 16 can be selected according to the shape of the electrode wire 01 and the shape of the circuit board 03. Figure 2 The above is only used as an example, specifically about the assembly of the planar electrode and the bracket 16 and supporting the head fixed recording or wireless recording. For example, the electrode wire 01 can be a flexible electrode, and the implantation needle 11 can be a steel needle.

[0064] The driving mechanism 20 can be selected as a cylinder or a hydraulic cylinder. The telescopic movement of the driving mechanism 20 can push the moving part 12 to reciprocate. The driving mechanism 20 can also be connected by a motor and a screw to realize the movement of the moving part 12. The moving part 12 is provided with a threaded hole, and the screw is threadedly matched with the threaded hole. The motor and the screw are matched to realize the reciprocating movement of the moving part 12 in the first direction. Since the driving mechanism 20 is controlled by the controller 90, the speed of the entire movement process is stable and the speed is precisely controlled, and the movement path of the driving mechanism 20 can also be precisely controlled. Therefore, the position where the implant needle 11 and the electrode wire 01 are implanted in the brain of the organism can be accurately determined, and at the same time, it cooperates with the camera module 30 in real time. The camera module 30 observes and locates the target area of ​​the brain A of the organism in real time, further improving the accuracy of the implantation process and reducing the error rate.

[0065] Similarly, the power component 13 can be selected as a cylinder or a hydraulic cylinder, and the displacement block 15 can be pushed to reciprocate through the telescopic movement of the power component 13; the power component 13 can also select a motor 133 and a screw 134 for transmission connection to realize the movement of the displacement block 15. The displacement block 15 is provided with a threaded hole, and the screw 134 is threadedly matched with the threaded hole. The motor 133 and the screw 134 cooperate to realize the reciprocating movement of the displacement block 15 in the first direction. Since the power assembly 13 is controlled by the controller 90, the speed of the entire movement process is stable and the speed is accurately controlled, and the movement path of the power assembly 13 can also be accurately controlled. Therefore, when the implant needle 11 is extracted from the brain of the organism, and at the same time, in real-time cooperation with the camera module 30 and the liquid supply mechanism 40, the camera module 30 observes and locates the target area of ​​the brain A of the organism in real time, and the liquid supply mechanism 40 works to uniformly and continuously provide liquid to the electrode wire 01 or the implant needle 11, so that the space between the electrode wire 01 and the implant needle 11 is filled with liquid, reducing the friction between the electrode wire 01 and the implant needle 11 to maintain stability during the separation process of the electrode wire 01 and the implant needle 11, further improving the stability during the extraction process, and reducing the error rate of the electrode wire 01 being taken out with the implant needle 11 or the electrode wire 01 being displaced.

[0066] For example, the liquid supply mechanism 40 may be a syringe or a sprayer, as long as it can continuously and evenly supply liquid. In addition, the liquid supplied by the liquid supply mechanism 40 may be physiological saline or a hemostatic agent.

[0067] refer to Figure 4-Figure 6 , Figure 4 A schematic diagram of the three-dimensional structure of an electrode wire 01 implantation device provided in an embodiment of the present invention without a camera module 30 and a liquid supply structure; Figure 5 A schematic diagram of an electrode wire 01 implantation device provided in an embodiment of the present invention without a camera module 30 and a liquid supply structure Figure 1 ; Figure 6 A schematic diagram of an electrode wire 01 implantation device provided in an embodiment of the present invention without a camera module 30 and a liquid supply structure Figure 2The implantation mechanism 10 further comprises a release assembly 14, a displacement block 15 and a bracket 16 for placing the electrode wire 01. The release assembly 14 is slidably provided with a moving part 12. The first end of the implantation needle 11 is connected to the moving end 132 of the power assembly 13 through the displacement block 15. The bracket 16 is detachably provided on the side of the moving part 12 facing the implantation needle 11, and in the second direction, the first direction is perpendicular to the second direction, ensuring that there is an overlapping part between the implantation needle 11 and the electrode wire 01. The overlapping part between the implantation needle 11 and the electrode wire 01 is at least located at the second end 112 of the implantation needle. The power assembly 13 drives the displacement block 15 to reciprocate relative to the moving part 12. When the displacement block 15 moves toward the fixed end 131 of the power assembly 13, the displacement block 15 abuts against the release assembly 14 and drives the release assembly 14 to move, so that the bracket 16 is separated from the moving part 12, and the electrode wire 01 located on the bracket 16 is separated from the implantation needle 11. The moving part 12 is formed with a blocking platform 121, and the blocking platform 121 is used to limit the movement path of the release rod 141. That is to say, through the action of the power component 13, the displacement block 15 is driven to move toward the fixed end 131 of the power component 13 (that is, the motor 133 of the power component 13), and the fixed boss 151 on the displacement block 15 is connected to the mounting hole 113 of the first end 111 of the implant needle, that is, the implant needle 11 moves along with the movement of the displacement block 15, and the displacement block 15 moves to the release component 14 to automatically release the electrode wire 01, that is, the electrode wire 01 is separated from the bracket 16. Through the simple linkage of the release component 14 and the displacement block 15, the action of automatically releasing the electrode wire 01 is realized, and the coordination precision is greatly improved, thereby effectively improving the stability during the extraction process and reducing the error rate of bringing the electrode wire 01 out with the implant needle 11 or the displacement of the electrode wire 01.

[0068] For ease of understanding, the working process of the electrode wire 01 implantation device provided in the embodiment of the present invention is described below. Figure 7-Figure 9 , Figure 7 A schematic structural diagram of a preparation stage of an electrode wire 01 implantation device provided by an embodiment of the present invention; Figure 8 A schematic diagram of the structure of an electrode wire 01 implantation device in the implantation stage provided by an embodiment of the present invention; Fig. 9 This is a schematic diagram of the structure of an electrode wire 01 implantation device after the implantation needle 11 is pulled out provided in an embodiment of the present invention.

[0069] Continue to refer Figure 7 and Figure 8 First, the implant consumable 1 is correctly installed on the bracket 16. At this time, the implant needle 11 is in the first state relative to the power component 13, and the second end 112 of the implant needle is physically connected to the electrode wire 01. After careful inspection to ensure that the installation is complete, the drive mechanism 20 is actuated to implant the implant needle 11 and the electrode wire 01 into the brain of the organism. At this time, the electrode wire 01 implantation device is Figure 7 Switch to Figure 8 .

[0070] Continue to refer Fig. 9 When the implantation is successful, the power assembly 13 starts to work and slowly pulls out the implant needle 11; during the whole process, the liquid supply mechanism 40 ensures that there is a continuous flow of water, water drops or water mist flowing to the electrode wire 01 or the implant needle 11, so that the space between the electrode wire 01 and the implant needle 11 is filled with liquid, reducing the friction between the electrode wire 01 and the implant needle 11 to maintain stability during the separation process of the electrode wire 01 and the implant needle 11, and separating the electrode wire 01 and the implant needle 11 in a simple way to facilitate the subsequent extraction of the implant needle 11 from the brain of the organism. Fig.10 Once the implant needle 11 is successfully extracted, the power component 13 continues to drive the displacement block 15 to move backward, and then the displacement block 15 moves to the release component 14 to automatically release the implant consumable 1 installed with the electrode wire 01, that is, the implant consumable 1 is separated from the bracket 16.

[0071] To clearly understand the specific movement process and structure of the release component 14, please refer to the following Fig.11 and Fig.12 , Fig.11 A schematic diagram of the structure of a release assembly 14 provided in an embodiment of the present invention; Fig.12 A schematic structural diagram of a fastener 142 provided in an embodiment of the present invention.

[0072] In some specific embodiments, the release assembly 14 includes a release rod 141 and a fastener 142. The movement of the fastener 142 along the second direction is controlled by the movement of the release rod 141 along the first direction. The release rod 141 and the fastener 142 are precisely linked. The release rod 141 is slidably arranged on the movable part 12 along the first direction. One end of the fastener 142 is in contact with the release rod 141, and the fastener 142 moves along the second direction to achieve relative fixation or separation of the bracket 16 and the movable part 12; when the fastener 142 is not in contact with the release rod 141, the other end of the fastener 142 provides pressure to relatively fix the bracket 16 and the movable part 12; when the fastener 142 is in contact with the release rod 141 and provides extrusion force, the other end of the fastener 142 is not in contact with the bracket 16, so that the movable part 12 is separated from the bracket 16.

For example, the elastic release member 1422 can be a spring or a tension spring. A pressing portion 14211 and a clamping portion 14212 are respectively formed at the two ends of the connecting rod 1421. The pressing portion 14211 and the clamping portion 14212 are connected by a connecting portion 14213. The specific shape of the connecting rod 1421 can be adjusted according to actual needs.
