The EchoBlock MSK Echogenic Non-Insulated Needle for ultrasound guided joint and tendon injections features patented corner cube reflectors (CCR™) providing multiple angled surfaces near the tip for maximum reflection even at steep injection angles. See the dots, see the target, and improve your success rate with reduced needle sticks. The faster, more accurate needle placement saves time and improves the quality of patient care. The absence of radiation is also safer for patients and staff.
