Description
技术领域 technical field
本发明涉及医疗器械领域，特别是涉及一种用于超声引导下的穿刺针。 The invention relates to the field of medical instruments, in particular to a puncture needle used under the guidance of ultrasound.
背景技术 Background technique
超声引导下神经阻滞技术是在高频便携式超声的引导下，麻醉科医师将穿刺针穿刺进入人体到达目标神经区域，在目标神经周围完成注射局部麻醉药物，产生满意的麻醉效果的麻醉方法。此种技术具有穿刺安全、定位精确、减少损伤、降低麻醉相关并发症的发生率、显著提高神经阻滞成功率等优点，已在临床上广泛应用。其具体操作方式是：麻醉科医师根据穿刺部位的不同，使患者保持适当体位，首先穿刺部位消毒铺洞巾，再通过调整高频线阵探头位置，使目标神经在超声图像上显示最清晰的影像，然后固定探头位置不变，穿刺点局部麻醉，采用平面内进针法，沿超声探头外侧端置入穿刺针，使穿刺针与探头的长轴保持平行方向进针，在超声图像上实时观察穿刺针进针路径，观察到针尖到达目标神经区域后，在目标神经周围完成注射局部麻醉药物。 Ultrasound-guided nerve block technology is an anesthesia method in which, under the guidance of high-frequency portable ultrasound, an anesthesiologist punctures a puncture needle into the human body to reach the target nerve area, completes the injection of local anesthetic drugs around the target nerve, and produces a satisfactory anesthesia effect. This technique has the advantages of safe puncture, precise positioning, less injury, lower incidence of anesthesia-related complications, and significantly improved success rate of nerve block, and has been widely used clinically. The specific operation method is as follows: the anesthesiologist keeps the patient in an appropriate position according to the different puncture sites, first disinfects the puncture site and lays a towel, and then adjusts the position of the high-frequency linear array probe so that the target nerve can be displayed most clearly on the ultrasound image. Imaging, then fix the position of the probe unchanged, local anesthesia at the puncture point, use the in-plane needle insertion method, insert the puncture needle along the outer end of the ultrasound probe, keep the puncture needle parallel to the long axis of the probe, and insert the needle in real time on the ultrasound image Observe the insertion path of the puncture needle, and after observing that the needle tip reaches the target nerve area, complete the injection of local anesthetic around the target nerve.
然而，在超声场中想要实时观察到清晰的穿刺针影像常常是困难的。由于这些神经阻滞穿刺针都是镜面反射体，并且存在穿刺针的进针方向与声束夹角偏小、穿刺针与探头的长轴不平行等原因，导致声波被反射进入体内它处而非向探头提供强的反射波。结果使穿刺针在超声图像中呈现出破损的或模糊的影像，甚至观察不到丝毫的穿刺针影像。麻醉科医师在操作过程中，观察不到清晰的穿刺针和目标神经影像，会通过反复调整探头及穿刺针位置，寻求清晰的影像效果。这样，不仅浪费时间，还增加穿刺损伤和并发症；如果麻醉医师勉强注射局部麻醉药物，还会使麻醉效果大打折扣，失去超声引导下神经阻滞的优势。 However, it is often difficult to observe a clear image of the puncture needle in real time in the ultrasound field. Because these nerve block puncture needles are mirror reflectors, and there are reasons such as the small angle between the needle insertion direction of the puncture needle and the sound beam, and the non-parallel long axis of the puncture needle and the probe, the sound waves are reflected into other places in the body and thus Do not provide strong reflected waves to the probe. As a result, the puncture needle appears damaged or blurred in the ultrasound image, and even the slightest image of the puncture needle cannot be observed. During the operation, the anesthesiologist cannot observe the clear puncture needle and the target nerve image, and will seek a clear image effect by repeatedly adjusting the position of the probe and puncture needle. This not only wastes time, but also increases puncture injuries and complications; if the anesthesiologist reluctantly injects local anesthetics, the effect of anesthesia will be greatly reduced, and the advantages of ultrasound-guided nerve block will be lost.
