Abstract
This application discloses a puncture device. The puncture device includes: a puncture tube allowing a guide wire to be inserted; and an operating handle including a handle housing, a ejection mechanism, and a trigger. The ejection mechanism is movably mounted on the handle housing, the puncture tube is fixedly connected to the ejection mechanism and inserted through the handle housing, and the trigger is movably mounted on the handle housing. When an external force is applied to the trigger, the ejection mechanism releases potential energy and propels the puncture tube forward rapidly, completing the puncture. Through this method, the puncture device provided by this application can more precisely control the puncture force and speed, avoiding over-puncture and reducing the risk of tissue damage, greatly improving the safety, accuracy, and efficiency of the puncture procedure. Furthermore, it enables zero-exchange operation, significantly simplifying the procedure for atrial septal puncture.
