Description

Technical Field

[0001] This invention relates to the field of bioelectrode technology, and in particular to a long-term implantable MEMS bioelectrode and its implantation device. Background Technology

[0002] The fabrication technology of MEMS bioelectrodes involves preparing patterned stimulation electrodes, recording electrodes, and grooved electrode circuit leads on a substrate. Multilayer impermeable insulating layers are grown using chemical vapor deposition. A wet etching process is then used to remove the impermeable insulating layers from the stimulation electrodes, recording electrodes, and circuit leads, exposing the metal films of the electrodes and leads. Electroplating is then used to form a thick-film structure for the electrode circuit leads, enabling reliable connection to external leads. The metals and insulating layers of the electrodes are made from highly biocompatible materials. After the electrode circuit and external leads are connected, all parts except the stimulation and recording electrodes are encapsulated in bio-polyurethane, ensuring excellent biocompatibility and suitability for long-term implantation in the human body.

[0003] In the process of implanting existing MEMS bioelectrodes into the human body, operators usually need to first use surgical instruments such as scalpels to cut open the patient's skin and then place the MEMS bioelectrode into the wound. Due to the small depth and length of the wound, it is inconvenient to manually place the MEMS bioelectrode into the wound. At the same time, because the wound is small, the range of motion during expansion cannot be too large, and the situation in the wound cannot be observed carefully. Sometimes it is also necessary to adjust the position of the MEMS bioelectrode in the wound. Summary of the Invention

[0017] In the above solution, by setting up an implantation component, when the operator implants the MEMS bioelectrode into the patient, the operator only needs to control the rotation of the crank to place the electrode in the corresponding position. After the electrode is implanted, the device can be removed from the human body. On the one hand, it realizes the implantation of MEMS bioelectrodes through simple operation, and on the other hand, it enables the device to be quickly removed from the human body after the MEMS bioelectrode is implanted, so that the operator can suture the patient's wound more quickly.

[0018] By setting up a cutting component, when the operator cuts the patient's skin, the operating lever can be moved to drive the cutting blade to cut the skin. On the one hand, this allows for more precise control of the wound depth and length during MEMS bioelectrode implantation. On the other hand, during the skin cutting process, a clamping plate can be placed in the wound to expand it, facilitating the implantation of the MEMS bioelectrode. This simultaneous expansion of the wound during MEMS bioelectrode implantation not only reduces the operation time but also decreases the difficulty of the implantation surgery.

[0039] like Figure 11 As shown, an embodiment of the present invention provides a long-term implantable MEMS bioelectrode, including an electrode body 5, a base 51 disposed in the electrode body 5, a sensing element 511 disposed at the four corners of the top of the base 51, a connecting ring 52 disposed in the middle of the top of the base 51, and an electronic interface 53 disposed on one side of the base 51.

[0040] In this embodiment, as Figure 1 As shown, a signal processing circuit is provided in the base 51, and the signal processing circuit is connected between the sensitive element 511 and the electronic interface 53.

[0041] like Figure 1 As shown, an embodiment of the present invention provides an implantation device for a long-term implantable MEMS bioelectrode, including an implantation component 3. The implantation component 3 is connected to the electrode body 5 via a connecting ring 52. The implantation component 3 is connected in a support part 2. A cutting component 4 is provided at the bottom of the support part 2, and support frames 1 are provided on both sides of the cutting component 4.

[0042] like Figures 1-2 and Figures 6-10 As shown, the support frame 1 includes a support rod 11 with a lifting groove 111. A lifting rod 12 is provided on one side of the support rod 11, and a limit knob 121 is threaded to one end of the lifting rod 12. The cutting assembly 4 includes a limiting part 41 with a clamping part 43 slidably connected therein. A cutting part 42 is provided in the clamping part 43. The limiting part 41 includes a limiting shell 411 with a limiting groove 412. A clamping block 431 of the clamping part 43 is slidably connected in the limiting groove 412. A disengagement part 432 is provided on the upper part of the clamping block 431, and an expansion part 433 is provided on the bottom of the clamping block 431. An operating rod 421 of the cutting part 42 is provided in the clamping block 431, and a fixing seat 422 is provided on the bottom of the operating rod 421. A cutting blade 423 is provided in the fixing seat 422. The top of the clamping block 431 is connected to the third lifting part via a movable plate 354. On plate 351, the release part 432 includes a trigger rod 4321, which is slidably connected to the upper part of the clamping block 431. A first spring 4322 is provided at one end of the trigger rod 4321, and a locking block 4323 is provided in the middle of the trigger rod 4321. An abutment rod 4324 is connected to the locking block 4323, and a second spring 4325 is provided on the abutment rod 4324. The abutment rod 4324 is connected to the clamping block 431 via the second spring 4325. 1. The expansion part 433 includes a third hydraulic rod 4331. Both ends of the third hydraulic rod 4331 are provided with piston rods. The third hydraulic rod 4331 is connected to the connecting block 4332 through the piston rods at both ends. The connecting block 4332 is connected to the clamping plate 4334 through the T-shaped block 4333. The T-shaped block 4333 is slidably connected to the bottom of the clamping block 431. The two clamping plates 4334 are provided with clamping posts 4335 on opposite sides.

[0043] In use, the device is first placed on the patient's body. The position is adjusted so that the implantation component 3 is directly above the location where the electrode needs to be implanted. Then, the operator moves the operating lever 421 within the limiting groove 412. During this movement, the lever 421 first moves vertically downwards, then horizontally, and finally vertically upwards. When the lever 421 moves vertically downwards, the cutting blade 423 inserts into the corresponding area of ​​the patient's skin. Then, when the operator moves it horizontally, the cutting blade 423 cuts... When the operating lever 421 moves horizontally, the cutting blade 423 moves laterally across the patient's skin, enlarging the wound. Finally, when the operating lever 421 moves upward, the cutting blade 423 leaves the skin. As the operator controls the operating lever 421 to pass the midpoint of the limiting groove 412, the clamping block 431 impacts the limiting groove 412. When the upper part of the clamping block 431 impacts the limiting groove 412, the trigger lever 4321 compresses the first spring 4322 under force, simultaneously moving laterally. As the trigger lever 4321 moves laterally, the clamping block 432... 3. The contact rod 4324 will disengage from the operating rod 421. At this point, the contact rod 4324 will spring up under the action of the second spring 4325 and enter the clamping block 431. Since the contact rod 4324, which was abutting against the operating rod 421, is now in the clamping block 431, the operating rod 421, without obstruction, will continue to cut the patient's skin independently, carrying the cutting blade 423. When the operating rod 421 moves to the end of the bottom of the limiting groove 412, it will move upwards, causing the cutting blade 423 to leave the patient's body. Then, when the operator needs to implant the electrode body 5 into the patient's body, the operator needs to... Rotate the crank 312 on the implantation component 3. At this time, the oil in the implantation component 3 will enter the third hydraulic rod 4331 through the hose. When the oil enters the third hydraulic rod 4331, the piston rods at both ends of the third hydraulic rod 4331 will extend. At this time, the two clamping plates 4334 will slide relative to each other at the bottom of the clamping block 431 to open the patient's wound. After the wound is opened, the implantation component 3 will implant the electrode body 5 into the patient's wound. When the electrode body 5 is in the appropriate position, the implantation component 3 will be reset under the operation of the operator, and the clamping plates 4334 will be withdrawn from the patient's body at the same time.

[0044] In this embodiment, as Figures 1-3 and Figures 6-10As shown, by adjusting the height of the lifting rod 12, the distance between the cutting blade 423 in the cutting assembly 4 and the human body can be controlled. Once the height is determined, the lifting rod 12 can be fixed on the support rod 11 by rotating the limit knob 121. At this time, the height of the cutting blade 423 will be fixed, which is equivalent to determining the depth at which the cutting blade 423 cuts into the patient's body, and also determining the depth at which the electrode body 5 is buried in the human body. The area directly below the implantation assembly 3 is where the electrode needs to be implanted. When the cutting part 42 moves to the middle position of the limit groove 412, the cutting part 42 is located directly below the implantation assembly 3. The third hydraulic rod 4331 is connected to the first hydraulic rod 331 and the second hydraulic rod 352 through hoses. When the oil in the first hydraulic rod 331 enters the third hydraulic rod 4331, the second hydraulic rod 352 cannot move because its height is fixed. At this time, the piston rods on both sides of the third hydraulic rod 4331 will move.

[0045] like Figure 1 and Figures 3-5As shown, the implantable component 3 includes a power unit 31, a limiting post 32 is provided on one side of the power unit 31, a first lifting part 33 is provided between the power unit 31 and the limiting post 32, a second lifting part 34 is provided below the first lifting part 33, and a third lifting part 35 is provided below the second lifting part 34. The power unit 31 includes an upper threaded post 311, a crank 312 is provided at the top of the upper threaded post 311, a ratchet is provided at the bottom of the upper threaded post 311, the bottom of the upper threaded post 311 is connected to the top of a lower threaded post 313, a one-way tooth 314 is provided at the top of the lower threaded post 313. The bottom of the support plate 22 is rotatably connected to one side of the top of the support plate 22 in the support part 2. The other side of the top of the support plate 22 is fixedly connected to the limit post 32. The top of the support plate 22 is provided with a support shell 21, and a power part 31 is rotatably connected in the support shell 21. The first lifting part 33 includes a first hydraulic rod 331. The top of the first hydraulic rod 331 is fixedly connected to a first lifting plate 332, and the bottom of the first hydraulic rod 331 is fixedly connected to an auxiliary plate 333. The second lifting part 34 includes an implantation part 341. The top of the implantation part 341 is fixedly connected to a second lifting plate 342. The third lifting part 35 includes a third lifting plate 342. 51. A second hydraulic rod 352 is provided on one side of the third lifting plate 351. A movable plate 354 is rotatably connected to the third lifting plate 351. A height limiting rod 353 is fixedly connected to the top of the third lifting plate 351. The same end of the first lifting plate 332, the second lifting plate 342, and the third lifting plate 351 are all slidably connected to the limiting post 32. The other ends of the first lifting plate 332, the second lifting plate 342, and the third lifting plate 351 are all threadedly connected to the power unit 31. One end of the auxiliary plate 333 is slidably connected to the limiting post 32, and the other end of the auxiliary plate 333 is slidably connected to the power unit 31. A height limiting hole 343 is provided in the lifting plate 342, and a height limiting rod 353 is provided directly below the height limiting hole 343. The implantation part 341 includes an implantation rod 3411. A first limiting block 3414 and a second limiting block 3415 are slidably connected to both sides of the implantation rod 3411. The second limiting block 3415 is engaged with one side of the bearing 3413, and a push rod 3412 is engaged with the other side of the bearing 3413. The push rod 3412 is slidably connected inside the implantation rod 3411, and the bottom of the push rod 3412 abuts against the electrode body 5. The bottom of the implantation rod 3411 is engaged with the connecting ring 52 of the electrode body 5.

[0046] When the operator cuts open the patient's skin and removes the cutting blade 423 from the body, the operator needs to turn the crank handle 312. When the crank handle 312 turns, the upper threaded column 311 will rotate. At this time, the first lifting part 33, the second lifting part 34, and the third lifting part 35 located on the upper threaded column 311 will move downward along the limiting column 32. When the third lifting plate 351 is located on the lower threaded column 313, the third lifting plate 351 will stop moving, and the second hydraulic rod 352 will be firmly locked on the support plate 22. The first lifting plate 332 and the second lifting plate 342 will continue to move downward. When the height limiting rod 353 passes through the height limiting hole 343, the height limiting rod 353 will abut against the auxiliary plate 333. At the bottom, when the auxiliary plate 333 is pressed against, the first lifting plate 332 and the second lifting plate 342 will continue to move. On the one hand, when the first lifting plate 332 moves, it will squeeze the first hydraulic rod 331 located between the first lifting plate 332 and the auxiliary plate 333. When the first hydraulic rod 331 is squeezed, the oil in the first hydraulic rod 331 will enter the third hydraulic rod 4331 through the hose. Since the third lifting plate 351 does not move, the oil in the first hydraulic rod 331 will completely enter the third hydraulic rod 4331. At this time, the third hydraulic rod 4331 will cause the two clamping plates 4334 to open. On the other hand, when the second lifting plate 342 continues to move, the bottom of the implanted rod 3411 will... The implant rod 3411 passes through the limiting shell 411 and enters the patient's wound. During the movement of the implant rod 3411, the first limiting block 3414 and the second limiting block 3415 will contact and be blocked by the two clamping posts 4335 on the clamping plate 4334. As the implant rod 3411 continues to move, the second limiting block 3415 will move upward within the implant rod 3411. When the second limiting block 3415 moves, it will cause the bearing 3413 to rotate, thereby causing the push rod 3412 to move downward. When the push rod 3412 moves downward, it will push the electrode body 5, which is stuck at the bottom of the implant rod 3411, off, allowing the electrode body 5 to enter the wound. After the electrode body 5 enters the wound, the operator reverses the crank handle 312. When 312 rotates in the reverse direction, the upper threaded column 311 will also rotate in the reverse direction. At this time, the first lifting plate 332 and the second lifting plate 342 will rise synchronously. During the rise of the second lifting plate 342, the implanted part 341 will rise and gradually move away from the patient's wound. Since the upper threaded column 311 rotates in the reverse direction, the ratchet in the upper threaded column 311 will be engaged on the one-way tooth 314 of the lower threaded column 313. At this time, the lower threaded column 313 will rotate synchronously with the upper threaded column 311. When the lower threaded column 313 rotates, the third lifting plate 351 will move upward synchronously with the first lifting plate 332 and the second lifting plate 342. During the movement of the third lifting plate 351, the second hydraulic rod 352 is engaged on the support plate 22.Therefore, the piston rod of the second hydraulic rod 352 will move upward with the third lifting plate 351. At this time, the second hydraulic rod 352 will draw oil from the third hydraulic rod 4331. After the oil in the third hydraulic rod 4331 is drawn out, the piston rods on both sides of the third hydraulic rod 4331 will retract. At this time, the two clamping plates 4334 will move closer to each other and return to their original positions. As the third lifting plate 351 continues to rise, the movable plate 354 will gradually be straightened. Finally, the third lifting plate 351 will pull the clamping part 43 out of the limiting part 41 through the movable plate 354, so that the clamping plate 4334 in the clamping part 43 will leave the patient's wound.

[0047] In this embodiment, as Figure 1 and Figures 3-5 As shown, a ratchet and a one-way tooth 314 are provided between the upper threaded post 311 and the lower threaded post 313. When the upper threaded post 311 rotates in the forward direction, the lower threaded post 313 will remain stationary. When the upper threaded post 311 rotates in the reverse direction, the lower threaded post 313 will be locked by the ratchet under the action of the one-way tooth 314, and will also rotate synchronously with the upper threaded post 311. When the bottom of the second hydraulic rod 352 is locked on the support plate 22, the third lifting plate 351 will also squeeze the second hydraulic rod 352 when it descends, making the connection between the second hydraulic rod 352 and the support plate 22 more tight. When the third lifting plate 351 rises, since the second hydraulic rod 352 is locked, the third lifting plate 351 can only pull up the piston rod in the second hydraulic rod 352.

[0048] The technical solution provided by this invention, by setting up an implantation component, allows operators to place the electrode in the corresponding position simply by controlling the rotation of a crank when implanting a MEMS bioelectrode into a patient. After the electrode is implanted, the device can be removed from the body. This achieves both simple operation for MEMS bioelectrode implantation and quick removal of the device from the body after implantation, allowing operators to suture the patient's wound more quickly.

[0049] By setting up a cutting component, when the operator cuts the patient's skin, the operating lever can be moved to drive the cutting blade to cut the skin. On the one hand, this allows for more precise control of the wound depth and length during MEMS bioelectrode implantation. On the other hand, during the skin cutting process, a clamping plate can be placed in the wound to expand it, facilitating the implantation of the MEMS bioelectrode. This simultaneous expansion of the wound during MEMS bioelectrode implantation not only reduces the operation time but also decreases the difficulty of the implantation surgery.
