Problems solved by technology

In addition, with the maturity and popularization of ultrasound-guided diagnostic and therapeutic techniques, many diagnostic and therapeutic procedures (such as percutaneous puncture of the cardiac atrial septum to place a left atrial manometry catheter) require bedside applications, while the femoral vein approach has a long operating path and limited space. Space requirements are high and cannot be implemented next to the bed

Abstract

The puncture needle comprises a needle body (1), a needle neck (2), a needle head (3), a tail end operating handle (4) and a locking device (6), the outer side faces of the needle body (1), the needle neck (2) and the needle head (3) are coated with ultra-smooth coatings, the needle body, the needle neck, the needle head and the tail end operating handle of the puncture needle have coaxiality, the needle neck (2) has flexibility, the puncture needle is used for puncturing the atrial septum of the heart, and the puncture needle is used for puncturing the atrial septum of the heart. The catheter can penetrate the atrial septum via an internal jugular vein path and can be used for guided delivery of an atrial indwelling catheter.

Description

technical field [0001] The application belongs to the field of medical devices, and in particular relates to a puncture needle for puncturing atrial septum of the heart. Background technique [0002] The general method of cardiac interseptal puncture is to insert the puncture set, such as the delivery sheath and the puncture needle inside it, into the patient's body through the femoral vein, and after the puncture set reaches a predetermined position, such as the heart interatrial septum, advance the puncture set. The puncture needle in the puncture set is used to puncture the interatrial septum of the heart. Usually, the front end of the interatrial septum puncture needle is generally knife-shaped or blunt, and the mechanical impact force formed by the puncture needle on the interatrial septum of the heart penetrates the interatrial septum of the heart during the puncture process, which may easily cause heart failure during the operation. Problems such as internal structur...
