|
Purpose: To evaluate the performance of a newly-designed ultrasound (US)-guided puncture device.
Materials and Method : A newly-designed US-guided puncture device was composed of a guide segment and an attachable segment. The guide segment allowed the needle to be placed in the plane of US view with a maximal degree of freedom, and the attachable segment was designed to attach to most convex US probes. Six operators punctured 144 targets in phantoms using either the new device (n = 72) or free-hand technique (n = 72). The number of required needle passages and the necessary procedure times were compared between the two groups.
Results: The number of required needle passages and the necessary procedure time were significantly reduced in five operators when the newly-designed US-guided puncture device was used (p < 0.05).
Conclusion: A newly-designed US-guided puncture device, which allows for a maximal degree of freedom in needle placement and can attach to most convex US probes, showed good performance in our study.
