Three-dimensional atrial septum puncture system

Abstract

The invention discloses a three-dimensional atrial septum puncture system. The three-dimensional atrial septum puncture system comprises a three-dimensional mapping and three-dimensional positioning assembly, an atrial septum puncture needle, a sheath catheter and an expanding tube, wherein the three-dimensional mapping and three-dimensional positioning assembly comprises a three-dimensional guidewire and a guide wire connecting wire, and at least two electrodes are arranged at each of the far end and the near and of the three-dimensional guide wire; the guide wire connecting wire is connected to the near end of the three-dimensional guide wire; at least two electrodes are arranged at each of the far end of the atrial septum puncture needle, the far end of the expanding tube, and the farend of the sheath catheter. For the three-dimensional atrial septum puncture system provided by the invention, under the condition that X-ray fluoroscopy / image is not used, the situation that whetherthe positions of the three-dimensional guide wire, the expanding tube, the sheath catheter and the puncture needle reach the puncture position or not can be clearly observed, accurate positioning andpuncturing are carried out, and the puncture risk caused by the fact that only the X-ray image is adopted, so that the puncture position can not be intuitively judged, is avoided.

Description

technical field [0001] The invention relates to an atrial septal puncture system, in particular to a three-dimensional atrial septal puncture system. Background technique [0002] At present, with the rapid development of interventional equipment and equipment, the application of cardiac interventional therapy is becoming more and more extensive, which makes atrial septal puncture more widely used. In 1959, Ross et al. reported the animal experimental study of atrial septal puncture, and in the same year, Cope and Rossdeng et al first applied atrial septal puncture to clinic. In the early atrial septal puncture, the method of directly puncturing the atrial septum with a puncture needle through the right atrial catheter was used. In 1960, Brockenbrough and Brawnwald et al. The tapered structure at the end increases the safety of operation. In 1977, Mullins et al. configured an outer sheath for the atrial septal puncture catheter, which further improved the operability and s...

AI Technical Summary

Problems solved by technology

Although ICE can accurately monitor and guide the running direction of the atrial septal puncture needle, so as to accurately locate the atrial septal puncture point, effectively avoid and reduce the risk of operation, but due to the expensive equipment, many hospitals do not have the conditions to equip it

At the same time, the use of ICE cannot solve the above-mentioned time-consuming and cumbersome puncture steps and the difficulty of puncturing the complex atrial septum

In addition to the above disadvantages, the real-time guidance of esophageal ultrasound for atrial septal puncture requires general anesthesia. In addition to the risks of anesthesia, esophageal diseases (such as varicose veins, ulcers, etc.) bring additional risks

[0004] And because X-rays have great harm to the body of patients and operators, this radiation can penetrate cells, damage DNA, and even induce some cancer cells, resulting in a high incidence of cancer, radiation dermatitis and many other radiation diseases
