Problems solved by technology

[0002] Although it has been reported in the literature that the atrial septum can be directly punctured directly from the superior vena cava using simple instruments, due to the extremely complex anatomical structure of the right atrium, standardized surgical instruments are urgently needed
ICE ultrasound (Intracardiac echocardiography, intracardiac ultrasound) can be used to accurately determine the interatrial septum and fossa ovale; but the high cost limits its application

Abstract

The invention discloses an ICE ultrasound superior vena cava atrial septum puncture device. The ICE ultrasound superior vena cava atrial septum puncture device comprises an ICE ultrasound tube, the ICE ultrasound tube is arranged in a semi-circular mode, and the ICE ultrasound tube is used to arrange the ICE ultrasound; a distal end of the ICE ultrasonic tube is provided with a bell mouth, and a tip end of the ICE ultrasonic tube is provided with a cone structure. An outer tube sleeves the ICE ultrasonic tube, and a puncture channel is reserved between the inner wall of the outer tube and theouter wall of the ICE ultrasonic tube for setting a puncture needle. The ICE ultrasound tube of the present invention is directly close to a puncture site of the heart, so that the ultrasound imagingis clearer.

Description

technical field [0001] The invention relates to the technical field of surgical instruments, in particular to the technical field of an ICE ultrasonic transatrial septal puncture device through the superior vena cava. Background technique [0002] Although it has been reported in the literature that the atrial septum can be directly punctured directly from the superior vena cava using simple instruments, due to the extremely complex anatomical structure of the right atrium, standardized surgical instruments are urgently needed. ICE ultrasound (Intracardiac echocardiography, intracardiac ultrasound) can be used to accurately determine the interatrial septum and fossa ovale; but the high cost limits its application. Contents of the invention [0003] In view of the above shortcomings, a transseptal puncture device for ICE ultrasound through the superior vena cava is designed, which can make the use of ICE ultrasound repeatable and reduce its use cost. [0004] In order to a...
