This UBE aspirator set consists of two curved tubes in thick and thin sizes for dual-channel spinal endoscopic surgery. The angled shaft reaches deep intervertebral lesions; the thick tube rapidly removes blood and bone debris, while the thin tube precisely clears tiny tissue fragments around nerves. Standard threaded rear connectors fit negative pressure suction devices directly. The smooth rounded tip avoids lacerating dura mater and nerve roots during suction. Integrally made of medical stainless steel with smooth inner bore to prevent clogging, it is corrosion-resistant and reusable after repeated autoclave sterilization.
