Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an ultrasound-guided nerve block puncture stent for clinical anesthesia. Background Art

[0002] Ultrasound-guided nerve blocks have become the main practice of modern regional anesthesia; in clinical practice, commonly used blocks (Plan A block) include: interscalene level brachial plexus block, axillary level brachial plexus block, thoracic erector spinae block, quadratus lumborum, rectus sheath block, lumbar plexus block, sciatic nerve, femoral nerve block, adductor canal block and popliteal level sciatic nerve block. The anatomical structures that should be identified during ultrasound scanning, during the operation, carefully check and identify more anatomical structures to ensure that the puncture point and puncture path avoid damage to blood vessels and nerves is logical.

[0003] In summary, the current ultrasound-guided nerve block puncture process in anesthesia clinics has the following technical problems: during blockade, blind puncture may cause block failure because the specific position cannot be determined. The existing technology uses ultrasound as an auxiliary tool to observe the anatomical structure where the nerve block is required and the position of the puncture needle. It is divided into out-of-plane needle insertion and in-plane needle insertion based on the positional relationship between the puncture needle and the ultrasound probe. Although the position of the puncture needle tip can be observed at any time using ultrasound when the needle is inserted in the same plane as the long axis of the ultrasound probe, it is technically simpler to insert the needle in the vertical direction for nerve blockade. For operators with insufficient experience in ultrasound examination, it is difficult to observe when the needle is inserted in the same axial plane as the long axis of the ultrasound probe; when a 50mm (2-inch) puncture needle is inserted perpendicular to the probe and the sound beam, the complete puncture needle image cannot be observed on the ultrasound image. Only the cross-section of the puncture needle can be observed. When the needle is inserted, it appears as a point-like high echo on the image. The probe needs to be slightly turned or tilted to determine the exact position of the puncture needle, rather than just observing the cross-sectional image of the puncture needle. However, after finding the image, because the position of the ultrasound probe is controlled by the hand, during the puncture process, due to the non-fixed state, the ultrasound probe may be slightly displaced, resulting in the problem of losing the puncture needle.
