A new device for sonographically controlled follicular puncture was introduced which improves both safety and comfort during egg retrieval. A steering attachment developed especially for the transducer of the DIASONICS DS 1 sector scanner increased the precision of transabdominal-transvesical follicular puncture. The "two-instrument method" (aspiration needle gliding smoothly within a trocar) ensured highly reliable, continuous sonographic imaging of the aspiration needle as well as precise puncture without the procedure being hindered by tissue resistance. Sonographically controlled follicular puncture under epidural anesthesia reduces procedure-related risk and patient stress.
一种用于超声控制卵泡穿刺的新设备被引入，该设备提高了取卵过程中的安全性和舒适度。专门为DIASONICS DS 1扇形扫描仪的换能器开发的转向附件提高了经腹-经膀胱卵泡穿刺的精度。“双器械法”（抽吸针在套管针内平稳滑动）确保了对抽吸针进行高度可靠、连续的超声成像，以及精确穿刺，且该操作不会受到组织阻力的阻碍。硬膜外麻醉下的超声控制卵泡穿刺可降低与操作相关的风险和患者的应激反应。
