AI Technical Summary
Existing sharp needles are prone to rupturing small arteries, small veins, or collecting system mucosa during percutaneous renal puncture. Furthermore, ultrasound-guided positioning is inaccurate, making it difficult to determine the spatial relationship between the needle tip and the target renal calyx, blood vessels, and stones in real time, which increases the risk of bleeding and puncture positioning errors.
A blunt puncture guidance system based on ultrasound imaging and vascular avoidance is adopted, including a rounded blunt needle tip, imaging structure, channel connection structure and safety sensing structure. It provides visual indication of needle tip position and depth through ultrasound guidance, reduces the risk of vascular cutting damage, and enables the establishment of continuous operation channels.
It improves the accuracy and safety of puncture positioning, reduces the risk of vascular cutting damage, ensures puncture efficiency, and achieves a smooth connection from puncture to channel establishment, reducing tissue damage and positioning deviation.
