| 目的 通过模拟实验验证数字陀螺仪与超声集合引导经皮穿刺术的精准性。方法 自制两种一次性实验体模：体模A内置直径1.0 cm球形水囊，水囊中心距A表面5.0 cm，用于模拟浅表脏器靶标的穿刺实验；体模B内置直径1.5 cm水囊，水囊中心距B表面10.0 cm，用于模拟深部脏器靶标的穿刺实验。对体模A组采用斜向穿刺进针，体模B组采用垂直方向穿刺进针。以数字陀螺仪与超声集合引导穿刺和超声定位徒手穿刺方法，分别对A、B重复穿刺10次，记录每组穿刺命中次数，计算命中率。结果 对体模A组采用数字陀螺仪与超声集合引导穿刺命中8次，命中率80.00%（8/10）；超声定位徒手穿刺命中3次，命中率30.00%（3/10）。对体模B组采用数字陀螺仪与超声集合引导穿刺，命中9次，命中率90.00%（9/10）；超声定位徒手穿刺命中4次，命中率40.00%（4/10）。数字陀螺仪与超声集合引导穿刺命中率均明显高于超声定位徒手穿刺（P均<0.05）。结论 数字陀螺仪与超声集合引导可为穿刺模拟实验中穿刺靶标提供精准的空间位置，精准引导穿刺针的进针角度和方向，有望成为一种全新的经皮穿刺导航技术。 |

| Objective To verify the precision of percutaneous puncture guided by digital gyroscope combined with ultrasound through simulation experiment. Methods Two kinds of homemade disposable experimental body models were prepared. A spherical water sac with diameter of 1.0 cm was placed in model A, and the distance of water sac center from the surface of A was 5.0 cm. Model A was used for simulation experiment of puncture superficial organ targets. A spherical water sac with diameter of 1.5 cm was placed in model B, and the distance of water sac center from the surface of B was 10.0 cm. Model B was used for simulation experiment of puncture deep viscera targets. Oblique puncture was performed in model A group, while vertical puncture was performed in model B group. Percutaneous puncture guided by digital gyroscope combined with ultrasound and ultrasound locating unarmed puncture methods were performed 10 times in model A and B group, respectively. The puncture hit number was recorded and the hit rate was calculated in each group. Results In model A group, percutaneous puncture guided by digital gyroscope combined with ultrasound made hit for 8 times and non-hit for 2 times, with the hit rate of 80.00% (8/10), while ultrasound locating unarmed puncture made hit for 3 times and non-hit 7 times, with the hit rate of 30.00% (3/10). In model B group, percutaneous puncture guided by digital gyroscope combined with ultrasound made hit for 9 times and non-hit for 1 time, with the hit rate of 90.00% (9/10), while ultrasound locating unarmed puncture made hit for 4 times and non-hit for 6 times, with the hit rate of 40.00% (4/10). In both groups, the hit rate of percutaneous puncture guided by digital gyroscope combined with ultrasound was higher than that of ultrasound locating unarmed puncture (both P<0.05). Conclusion Digital gyroscope combined with ultrasound can provide exact space position for puncture targets in simulation experiment and exactly guide choosing puncture angle and direction. It is expected to become a new kind of percutaneous puncture navigation technology. |
