AI Technical Summary
Existing ultrasound-guided techniques are complex and costly to use for deep nerve blocks or when strict aseptic techniques are required. Furthermore, the use of sterile protective sleeves can degrade ultrasound image quality and make it difficult to fully display the puncture needle trajectory. In particular, for certain patient groups, soft tissue deformation and respiratory movements can affect the needle insertion path, leading to deviation and the risk of nerve damage.
The laser emitter works in conjunction with the positioning frame to construct a three-dimensional spatial positioning reference through the laser beam. Combined with the locking function of the flexible arm, it enables dynamic calibration of the puncture needle path, eliminates image distortion and puncture needle trajectory deviation, and ensures puncture accuracy.
It improves the accuracy and safety of puncture procedures, reduces operational complexity and consumable costs, and avoids image distortion and needle trajectory deviation caused by sterile protective sleeves, making it particularly suitable for special patient groups.
