Cardiac atrial septal puncture assembly

Abstract

The invention relates to the field of medical instruments, and aims to provide a cardiac atrial septal puncture assembly. The cardiac atrial septal puncture assembly comprises a long catheter, whereina micro thread is formed in one end of the long catheter, and one end of the long catheter is connected with an expansion tube through the micro thread; a connector is fixedly connected to the outerwall of the end, away from the expansion tube, of the long catheter in a sleeving mode, and a conversion connector is welded to the outer wall of one end of the connector; an inner core tube is arranged in the long catheter, and the conversion connector is connected to the outer wall of the long catheter in a sleeving mode; and a fixing sleeve is fixedly connected to the outer wall of the long catheter in a sleeving mode, and a positioning plate is welded to the outer wall of the top of the fixing sleeve. The cardiac atrial septal puncture assembly has the advantages that ablation puncture isachieved through an electrode, the operation steps are simplified, the operation risk is reduced, people can conveniently adjust and control the breakdown voltage on the electrode, liquid substances can be conveyed into blood vessels of a patient, the patient has normal vital signs, and the operation safety of the device on the patient is improved.

Description

Technical field [0001] The invention relates to the field of medical devices, and in particular to a cardiac atrial septal puncture assembly. Background technique [0002] Atrial septal defect is the most common congenital heart disease. Traditional surgical repair requires long operation time, large trauma, and slow postoperative recovery, making it increasingly difficult to accept. In recent years, with the continuous innovation of medical equipment and the advancement of medical technology, atrial septal defect closure surgery has become an important surgical method for the treatment of atrial septal defect due to its advantages of minimal invasiveness, aesthetics, and quick recovery. [0003] Existing treatment methods mostly use puncture needles. When the puncture needle penetrates and passes through the expansion tube, the stainless steel needle tip will inevitably scrape a strand of material in the expansion tube of polymer material. Once these materials enter the heart cavi...

AI Technical Summary

Problems solved by technology

To realize the puncture, the puncture needle and the expansion tube must be continuously advanced. At the moment when the expansion tube penetrates into the atrial septal defect, due to the thrust inertia, the puncture needle and the expansion tube continue to move together, and there is a risk of direct insertion or even puncturing the atrial wall
