Description

一种智能化接骨板
技术领域
本发明涉及医疗器械领域，尤其涉及一种智能化接骨板。
背景技术
现有的接骨板植入后需要反复进行X光、CT检查辅助判断患者是否达到骨愈合，患者需要反复到医院进行多次检查，涉及人力成本、时间成本、经济成本、放射危害等问题。并且，现有的接骨板对植入后的自身位置、应力情况，以及患者的肢体运动、康复锻炼时间、休息时间、平卧时间等缺乏记录和反馈。
发明内容
本发明旨在提供一种智能化接骨板(包含四肢长骨、锁骨、肩胛骨、胸骨、肋骨、脊椎骨、骨盆等)，可以在不进行X光、CT检查的情况下，准确的判定患者是否达到骨融合，增加骨融合判定的准确率，并且能够对接骨板植入后的自身位置、应力情况等进行记录并反馈。
为达到上述目的，本发明是采用以下技术方案实现的：
本发明公开的智能化接骨板，包括板体A和板体B，所述板体A、板体B通过弹性件对接；板体A和板体B的相向端均布置有应力传感器和位移传感器，所述弹性件上设有应力传感器和位移传感器。
优选的，所述弹性件的一端与板体A或板体B的一端固连，弹性件的另一端与板体B或板体A通过紧固件连接。
优选的，所述板体B设有卡槽，所述板体B的一端嵌装在卡槽中，弹性件固连板体B的一端，板体B的另一端位于卡槽外，所述紧固件穿过板体A的表面固定弹性件的另一端，所述卡槽的四面侧壁封闭。
进一步的，所述卡槽中设有限位装置。
进一步的，板体A和板体B均设有安装孔，所述安装孔处设有应力传感器和位移传感器。
优选的，所述弹性件包括弹簧、弹片或交叉弹片。
进一步的，本发明还包括智能终端，所述应力传感器、位移传感器均与智能终端无线连接。
优选的，所述智能终端为手机。
进一步的，所述板体A或板体B上布置有重力传感器，板体A或板体B表面设有化学传感器，所述重力传感器、化学传感器均与智能终端无线连接。
本发明的工作原理如下：
当接骨板植入后，由于人体重力的存在，上下2个骨骼会对接骨板产生压迫，弹性部件会变形，弹性件处的应力感受器记录应力的大小并传输到连接的智能终端，医生可以在医生端APP中观察到；
当患者运动时，比如身体变化姿势时，弹性部件会再次变形，板体A、板体B之间的间隙会发生微动产生位移、应力也会产生相应变化；微动和位移会被位移感受器、应力感受器记录传输到智能终端；姿势的改变引起重力方向的改变，会被重力感受器记录传输到智能终端。
当患者还未达到骨愈合的时候，患者重力主要通过接骨板传输，应力主要集中在接骨板(接骨板的一个主要功能就是支撑作用)，人的活动和变化姿势的时候，会产生应力改变、会有微动和位移产生，也有重力方向改变。当融合后，骨头将上下骨骼连接，起到牢固支撑作用；这个时候，接骨板就像是混泥土内部的一个空洞里的一个部件，不承担应力、不产生微动和位移，但是仍有重力方向改变。此时位移感受器记录值为0，应力感受器记录的应力为固定在一个较低的值。此时，医生就可以通过记录的应力和位移曲线来判断患者术后是否达到椎间融合，是否完全康复，从而避免反复X光和CT等放射照射。
本发明的有益效果如下：
1、本发明能够智能化实现自身判断是否达到骨愈合！避免传统的X光、CT放射学方法的放射危害，减少医患双方由此产生的时间、人力、经济成本，降低社会医疗负担(最主要的)；
2、本发明具有纵向弹性，增加了骨折断端的应力刺激，有利早期康复。
3、本发明增加了螺钉与接骨板连接处的位移和应力检测，可以智能化判断接骨板是否有松动、断裂、螺钉退出等并发症；
4、本发明通过应力传感器、位移传感器、重力传感器记录的数据，手机APP会自动分析和转化成患者曲线，从而分析得出患者的活动度、活动时间、平卧时间、康复训练锻炼时间等患者数据用于医生更好的指导患者康复锻炼；
5、本发明的化学传感器，能获取接骨板表面PH值、钛合金碎屑、PEEK碎屑等材料碎屑等局部情况，并传输到APP，用于医生判断是否有材料降解、失效等；
6、本发明可以准确的判定患者是否骨愈合，增加融合判定的准确率(现有的X光、CT判定融合的准确率较低，仅仅为50-70％左右)；
7、本发明可以为孕妇、备孕人员、其他放射危害敏感人员使用(孕妇、备孕人员因为担心放射危害，又合并需要骨科手术的疾病，往往处于尴尬两难的境地)。
