Embodiment 1

[0084] Such as Figure 1-9 As shown, a guiding sheath for atrial septal puncture and a catheter 11 for atrial septal puncture used in conjunction with it according to the present invention.

[0085] The guiding sheath includes a terminal sheath 1 and an adjustable curved section 2 connected thereto, and the two ends of the adjustable curved section 2 are provided with a first sheath magnetic positioning sensor 61 and a second sheath magnetic positioning sensor 61 respectively. Sensor 62, the first sheath magnetic positioning sensor 61 is close to the terminal sheath 1, the first sheath magnetic positioning sensor 61 is close to the end of the terminal sheath 1 to the free end of the terminal sheath 1 The distance is L;

[0086] The catheter 11 can move axially along the guiding sheath, the distance from the end of the first sheath magnetic positioning sensor 61 close to the end sheath 1 to the free end of the catheter 11 is D, and the catheter 11 The free end is provided wit...

Embodiment 2

[0100] Such as Figure 1-9 As shown, a kind of fossa ovalis detection method of the present invention is characterized in that, application guide sheath tube and catheter 11 as described in embodiment 1, this method comprises the following steps:

[0101] A. Perform vascular puncture to place the guide sheath into the lower chamber of the atrium;

[0102] B. Putting the catheter 11 in the guiding sheath so that the electrodes at the end of the catheter 11 are exposed to the terminal sheath 1;

[0103] C. Manipulating the catheter 11 and the guiding sheath to construct a physical model of the right atrium;

[0104] D, determine the fossa ovale position range according to the right atrium physical model;

[0105] E. If Figure 7 and 8 As shown, the terminal sheath 1 is perpendicular to the range of the fossa ovalis and close to the fossa ovalis to fix the guiding sheath;

[0106] F. If Figure 9 As shown, extend the free end of the catheter 11 out of the terminal sheath 1,...

Abstract

The invention discloses a guiding sheath tube, a catheter and a fossa ovale detection method for atrial septal puncture. The guiding sheath tube comprises a terminal sheath tube and an adjustable bendable section connected thereto, and two ends of the adjustable bendable section are respectively provided with There are a first sheath magnetic positioning sensor and a second sheath magnetic positioning sensor, the first sheath magnetic positioning sensor is close to the end sheath, and the first sheath magnetic positioning sensor is close to the distance from the end of the end sheath to the free end of the end sheath is L; the guide sheath is used to match the catheter, the catheter can move axially along the guide sheath, and the distance from the end of the first sheath magnetic positioning sensor close to the end sheath to the free end of the catheter is D, and the free end of the catheter is set as L. There are pressure sensors and catheter magnetic positioning sensors. The introducing sheath makes the atrial septal puncture more accurate and effective, saves the puncture time, and more importantly, the present invention can realize zero radiation during the puncture process, and better protect the body of the doctor and the patient from radiation. The structure is simple, the use is convenient, and the effect is good.

Description

technical field [0001] The invention relates to the technical field of medical guidance puncture, in particular to a guiding sheath, catheter and fossa ovale detection method for atrial septal puncture. Background technique [0002] Atrial septal puncture was first reported by Ross et al. in 1959, and then Brockenbrough and Mullins et al. improved the puncture needle, sheath and puncture technique on this basis. At that time, it was mainly used for left heart catheterization for valvular lesions. Now, with the increasing popularity of catheter ablation of atrial fibrillation, atrial septal puncture has become a common clinical technique. [0003] Atrial septal puncture can be used in catheter ablation of left bypass via transseptal approach, ablation of atrial fibrillation, ablation of left atrial tachycardia and ablation of left atrium atrial flutter. Alternative pathways and essential supplements for ablation of disorders. [0004] The percutaneous catheter cannot reach ...
