Embodiment Construction

[0016] The present invention is described below based on examples, but the present invention is not limited to these examples.

[0017] The meanings of the orientation terms "near end" and "far end" adopted in the present invention are centered on the heart, the one near the heart is called the near end, and the one far away from the heart is called the far end.

[0018] An adjustable bending puncture system for neonates with pulmonary atresia, comprising: an outer sheath 1 and a puncture needle 2, the outer sheath 1 is placed outside the puncture needle 2, both are flexible and can be bent, the outer sheath 1 and the puncture needle The needle 2 is flexible at least in the middle, preferably the whole section is flexible. Flexibility means manual return to shape after bending. The flexibility of the outer sheath 1 and the puncture needle 2 enables it to be bent, and the bending angle of the outer sheath 1 and the puncture needle 2 can be adjusted. If the initial bending angl...

Abstract

The invention relates to the field of medical devices, in particular to a bending-adjustable puncture system and puncture method of pulmonary artery atresia of the newborn. The puncture system comprises an outer shell and a puncture needle, the outer shell is arranged outside the puncture needle in a sleeving mode, both the outer shell and the puncture needle can be flexibly bent, and at least the middle portions of the outer shell and the puncture needle are flexible. The puncture method comprises the steps that bending adjustment is conducted on the puncture system, so that the bending angle of the puncture system is matched with a right ventricular outflow tract-main pulmonary artery; then the puncture is conducted to enable the right ventricle to be connected with the pulmonary artery. The puncture system can be bent to an appropriate angle to complete the puncture based on angles of the right ventricular outflow tract-main pulmonary arteries of different child patients, and serious complications such as cardiac perforation, cardiac tamponade and the like are avoided, so that the successful rate of surgeries is ensured.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an adjustable bending puncture system and a puncture method for neonatal pulmonary atresia. Background technique [0002] Pulmonary atresia is characterized by disruption of communication between the right ventricle and the pulmonary artery. Usually, according to the presence or absence of ventricular septal defect, it is divided into two categories, namely pulmonary atresia with ventricular septum and pulmonary atresia with intact ventricular septum. The main treatment for pulmonary atresia is surgery under cardiopulmonary bypass, which has high risks and many complications. Some patients can be treated with medical intervention, but the operation distance from the femoral vessel to the heart is long, the maneuverability is poor, the risk is high, and the success rate of the operation is low. Contents of the invention [0003] In view of this, the present invention provides an...
