We have developed a needle for direct percutaneous access in order to introduce the flexible wire with a single puncture, without creating two parallel tracks, thereby affording a lower morbidity than the conventional technique.
The needle consists of an internal and an external device, with different lengths and diameters, that let us first create the access to the urinary tract with the inner device and then dilate with the outer device in order to introduce the metallic wire with a single puncture, sliding the outer over the inner device.
We can achieve the same number of percutaneous accesses with less morbidity since less punctures are required to create the track.
This is a useful needle for any type percutaneous access.
我们研发了一种用于直接经皮穿刺的针，以便通过单次穿刺引入柔性导丝，而无需创建两条平行通道，从而使发病率低于传统技术。
该针由内部和外部装置组成，长度和直径不同，使我们能够先用内部装置建立进入尿路的通道，然后用外部装置进行扩张，以便通过单次穿刺引入金属导丝，将外部装置套在内部装置上滑动。
由于创建通道所需的穿刺次数减少，我们可以在发病率较低的情况下实现相同数量的经皮穿刺。
这是一种适用于任何类型经皮穿刺的有用针具。
