Excellent needle visualization is critical for the safety and success of ultrasound-guided puncture procedures. However, optimal visualization is often challenging when a needle is inserted at a steep angle via in-plane technique. We hypothesized that a water cushion filled under the probe would result in better needle visualization via artificial beam steering during the ultrasound-guided in-plane technique. We simulated human soft tissue with pork and two targets with rigid needles. A water cushion was also made beforehand: a surgical glove was filled with an appropriate amount of water. Ultrasound-guided in-plane puncture procedures for the two targets were performed without and with the water cushion under the ultrasound probe. Clear ultrasound images of the needles were captured for objective visualization analysis. The angles between the ultrasound beam and the puncture needle were measured. The visualization of the needle was significantly better at shallow angles than at steep angles. After using A water cushion, the needle was clearly displayed again at a steep insertion angle. During the ultrasound-guided in-plane technique, needle visualization at a steep insertion angle can be improved by artificial beam steering generated with a water cushion.
出色的针可视化对于超声引导穿刺手术的安全性和成功率至关重要。然而，当通过平面内技术以陡峭角度插入针时，最佳可视化通常具有挑战性。我们假设在探头下方填充水垫将通过超声引导平面内技术期间的人工束转向导致更好的针可视化。我们用猪肉模拟人体软组织并用刚性针模拟两个目标。还预先制作了一个水垫：用手术手套填充适量的水。在超声探头下方有和没有水垫的情况下，对两个目标进行超声引导平面内穿刺手术。捕获针的清晰超声图像以进行客观可视化分析。测量超声束与穿刺针之间的角度。在浅角度下针的可视化明显优于在陡峭角度下。使用水垫后，在陡峭的插入角度下针再次清晰显示。在超声引导平面内技术期间，通过用水垫产生的人工束转向可以改善在陡峭插入角度下的针可视化。
