To the Editor,
The fixed probe makes it possible for a person to inject the anesthetic agent and insert a catheter alone. Furthermore, the laser navigation helps to pay attention to the plane of the ultrasound beam. We used the probe holder previously developed by us for a linear probe (S-Nerve HFL50x/15-6®, FUJIFILM Medical Co., Ltd., Tokyo, Japan). This device is consisting of three parts, the flexible arm (Flexible arm®, PROKIZAI.COM Co., Ltd., Naha, Japan), the probe holder, and the laser module (Line laser module®, Denshi Tusho Co. Ltd., Tokyo, Japan). The laser navigation and the probe holder were mounted on the flexible arm (Fig. 1b) using deformable plastic (Moldable Plastic®, TFabWorks, Chiba, Japan). Although this combined device is not in commercial, this plastic can be deformed for any type of probes without special tools. It seems to be more stable than using free-hand laser navigation.
The insertion area was cleaned with povidone, and the sterile cover (Cathereeplus™, Nichiban CO. Ltd., Tokyo, Japan) was applied to the probe. Once “the best view” was fixed, the probe holder could keep the position throughout the procedure. We consider this combination as superior to that of the probe holder and the needle guide device because the needle guide is useful only when the insertion site is near the probe. In addition, the laser navigation can predict the cross-section of the ultrasound beam. Despite some clinical limitation, the use of a probe holder combined with laser navigation is very useful for administering ultrasound-guided nerve blocks.
