AI Technical Summary

Technical Problem

Traditional puncture methods are complicated and carry a risk of tissue damage because the atrial septum conditions vary from patient to patient, making the puncture process difficult to control precisely.

Method used

A puncture device is employed, which utilizes a catapult mechanism to release potential energy to propel the puncture tube forward rapidly. Combined with a trigger element, precise control is achieved. The puncture tube is designed with both flexibility and rigidity, and is equipped with an outer sheath and flushing components to achieve zero-exchange operation.

Benefits of technology

It enables precise control of puncture force and speed, reduces the risk of tissue damage, simplifies the operation process, and improves the safety, accuracy and efficiency of puncture surgery.

Abstract

The invention discloses a puncture device. The puncture device comprises a puncture tube which allows a guide wire to be arranged in the puncture tube in a penetrating manner; the operating handle comprises a handle shell, an ejection mechanism and a trigger part, the ejection mechanism is movably arranged on the handle shell, the puncture tube is fixedly connected to the ejection mechanism and penetrates through the handle shell, and the trigger part is movably arranged on the handle shell; when external force is applied to the triggering piece, the ejection mechanism can release potential energy and drive the puncture tube to move forwards rapidly, and the puncture action is completed. By means of the mode, the puncture device can more accurately control the puncture strength and speed, excessive puncture is avoided, the tissue damage risk is reduced, the safety, accuracy and efficiency of a puncture operation are greatly improved, zero exchange operation can be achieved, and the operation process of the atrial septum paracentesis can be remarkably simplified.
