不可吸收缝合线辅助植入式柔性微电极及其制备方法Non-absorbable suture-assisted implantable flexible microelectrode and preparation method thereof

技术领域technical field

本发明涉及的是一种医用器械技术领域的微电极,具体是一种面向瘫痪康复的不可吸收缝合线辅助植入式柔性微电极及其制备方法。The invention relates to a microelectrode in the technical field of medical devices, in particular to a non-absorbable suture-assisted implantable flexible microelectrode for paralysis rehabilitation and a preparation method thereof.

背景技术Background technique

近年来,随着微机电系统(MEMS: Micro-Electro-Mechanical Systems)技术的不断进步,使得微电子设备和微传感器等微系统应用范围不断扩大,已广泛应用于多个领域,特别是医学领域。In recent years, with the continuous advancement of MEMS (Micro-Electro-Mechanical Systems) technology, the application range of micro-systems such as micro-electronic devices and micro-sensors has continued to expand, and has been widely used in many fields, especially in the medical field. .

面向瘫痪康复的微电极是一个重要的应用。骨骼肌是由神经支配的,但是如果神经出现损伤,骨骼肌就会麻痹或者瘫痪,不能完成运动功能。如果使用微电极把功能性电刺激信号加载到目标肌肉或者目标部位上,那么骨骼肌就会得到一定程度的康复,恢复一部分或者全部运动机能。Microelectrodes for paralysis rehabilitation are an important application. Skeletal muscles are innervated by nerves, but if the nerves are damaged, the skeletal muscles will be paralyzed or paralyzed, unable to perform motor functions. If the microelectrode is used to load the functional electrical stimulation signal to the target muscle or target site, then the skeletal muscle will be recovered to a certain extent, and some or all of the motor functions will be restored.

目前,对于植入式微电极的植入方法有很多种,常见的有:外科手术切开组织,在目标部位植入微电极,适用于长期植入;把微电极放在空心注射针头中,利用注射针头刺入组织,完成植入,适用于临时植入及在解剖学上比较简单的目标部位植入。At present, there are many implantation methods for implantable microelectrodes, the common ones are: surgical incision of tissue, implanting microelectrodes at the target site, which is suitable for long-term implantation; placing microelectrodes in hollow injection needles, using The injection needle penetrates into the tissue to complete the implantation, which is suitable for temporary implantation and implantation at relatively simple target sites in anatomy.

对于外科手术植入的方法,一方面创伤较大,另一方面在微电极植入后,微电极比较容易发生移位,与一开始植入时的部位发生偏离,造成微电极的刺激效果变差等不利影响。对于注射针头辅助植入的方法,由于注射针头可以在较少创伤的情况下刺入较深部位,所以对于相关实验是比较有用的,但临床上也存在植入后微电极易于移动的缺点。另外,对于解剖上比较复杂的部位,使用注射针头辅助植入的方法还容易对其他组织造成损伤,引起难以预计的问题。For the method of surgical implantation, on the one hand, the trauma is relatively large, and on the other hand, after the microelectrode is implanted, the microelectrode is relatively easy to shift, which deviates from the initial implantation site, resulting in a change in the stimulation effect of the microelectrode. adverse effects. As for the needle-assisted implantation method, since the injection needle can penetrate deeper parts with less trauma, it is more useful for related experiments, but there is also the disadvantage that the microelectrode is easy to move after implantation clinically. In addition, for anatomically complex parts, the method of using needle-assisted implantation is also likely to cause damage to other tissues, causing unpredictable problems.

经对现有技术的检索发现,Sachs, N. A., E. L. Chang等人在IEEE Trans Neural Syst Rehabil Eng 15(1): 67-75 ,2007撰文“Electrical stimulation of the paralyzed orbicularis oculi in rabbit”(用于兔子眼轮匝肌麻痹的电刺激),该技术采用在兔子上眼睑的皮下使用外科手术的方法植入刺激电极,并且在一定程度上实现了兔子的闭眼动作。但是对于需要长期植入的电极来说,这种方法会使电极比较容易滑动,偏离原来植入的部位,造成刺激效果变差,所以该方法在长期植入应用方面受到较多限制。After searching the prior art, it was found that Sachs, N. A., E. L. Chang et al wrote an article "Electrical stimulation of the paralyzed orbitalis oculi in IEEE Trans Neural Syst Rehabil Eng 15(1): 67-75, 2007 rabbit” (Electrical Stimulation for Rabbit Orbicularis Oculi Palsy), which uses surgical implantation of stimulating electrodes under the skin of the rabbit’s upper eyelid, and achieves the rabbit’s eye-closing movement to a certain extent. However, for electrodes that need to be implanted for a long time, this method will make the electrodes slide more easily and deviate from the original implanted site, resulting in poor stimulation effect. Therefore, this method is more limited in long-term implantation applications.

美国专利号:US8,010,200,“System for permanent electrode placement utilizing microelectrode recording methods”(一种利用微电极记录方法辅助放置永久微电极的系统),该技术公开了一种结合记录微电极与脑深部电刺激电极来改善植入电极部位的方法。该技术在脑深部电刺激电极中间做一个腔室,腔室容许记录微电极通过。可以根据需要,在植入脑深部电刺激电极之前,之后以及植入的过程中随时插入记录微电极来确定脑深部电刺激电极的植入位置是否合适。综上,目前对微电极植入方法的有关研究集中在植入时如何提高植入部位精确度的问题上,对由微电极植入后的长期部位精确度研究较少,因此,没有可用于长期保证微电极植入部位精确度的方法或系统。U.S. Patent No.: US8,010,200, "System for permanent electrode placement utilizing microelectrode recording methods" (a system that uses microelectrode recording methods to assist in the placement of permanent microelectrodes), this technology discloses a combination of recording microelectrode and brain Deep electrical stimulation electrodes to improve the method of implanting the electrode site. The technique creates a cavity in the middle of the deep brain stimulation electrodes, which allows the recording microelectrodes to pass through. According to needs, the recording microelectrode can be inserted at any time before, after and during the implantation of the deep brain electrical stimulation electrode to determine whether the implantation position of the deep brain electrical stimulation electrode is appropriate. In summary, the current research on microelectrode implantation methods focuses on how to improve the accuracy of the implanted site during implantation, and there are few studies on the long-term site accuracy after microelectrode implantation. A method or system for long-term assurance of microelectrode implant site accuracy.
