摘要： The invention discloses a three-dimensional atrial septal puncture method including positioning the heart from a body surface by a three-dimensional projection positioning method and displaying interventional instruments by the three-dimensional system and guiding the same into a heart cavity. The method also includes constructing a right atrium three-dimensional model by delivering a catheter with a positioning device to the right atrium and reconstructing and fusing pre-operative image data by the three-dimensional system. The method also includes setting parameters, connecting an interventional operating device with a pressure sensor tail wire and an electrode tail wire, and displaying a guidewire or a puncture needle. The method includes delivering and positioning the long sheath, analyzing and marking the fossa ovalis position by a structure and potential method. The method also includes analyzing the pressure difference between the left atrium and the right atrium, and judging whether the puncture is successful.

摘要： The invention discloses a three-dimensional atrial septal puncture method, comprising the steps of: positioning the heart from a body surface by a three-dimensional projection positioning method, displaying interventional instruments by the three-dimensional system and guiding the same into a heart cavity; constructing a right atrium three-dimensional model by delivering a catheter with a positioning device to the right atrium; reconstructing and fusing pre-operative image data by the three-dimensional system; mainly analyzing the right atrial septal side to mark the puncture site; setting parameters of the three-dimensional system, connecting an interventional operating device with a pressure sensor tail wire and an electrode tail wire, connecting the interventional operating device to the three-dimensional system, and displaying a guidewire or a puncture needle in the three-dimensional system in real time; delivering a long sheath into the superior vena cava, and positioning the long sheath by using the three-dimensional system; analyzing and marking the fossa ovalis position by a structure and potential method, delivering a puncture needle to perform an atrial septal puncture at a marked site under the guidance of the three-dimensional system; analyzing the pressure difference between the left atrium and the right atrium, and judging whether the puncture is successful; and sequentially delivering the guidewire and the long sheath into the left atrium after a successful atrial septal puncture. The three-dimensional atrial septal puncture method of the invention is operated entirely under a three-dimensional interface without the need for X-rays and contrast agents. The accuracy and success rate of atrial septal puncture can be improved, and safety is guaranteed completely.
