Multifunctional temporary pace-making electrode catheter

Abstract

The invention discloses a multifunctional temporary pace-making electrode catheter which comprises a catheter body, the catheter body is provided with an inner cavity, an end electrode, a balloon and a ring electrode are sequentially arranged at the far end of the catheter body, the end electrode is arranged at the tip of the far end of the catheter body, the ring electrode is arranged on a catheter body at the far end of the catheter body, and the balloon is arranged between the end electrode and the ring electrode. A connecting handle, a tail line and a Y-shaped connecting valve are arranged at the near end of the catheter, the far end of the Y-shaped connecting valve is communicated with the near end of an inner cavity of the catheter and fixed to the connecting handle, an end electrode wire and a ring electrode wire in the end electrode and the ring electrode extend to the connecting handle through a catheter body of the catheter and are electrically connected with the tail line, and the balloon is communicated with the inner cavity. And the far end of the tail wire is fixed on the connecting handle. Compared with the prior art, the temporary pace-making electrode catheter has the advantages that the corresponding temporary pace-making mode is selected according to needs, different clinical requirements are met, the operation efficiency is improved, and the universality of the temporary pace-making electrode catheter is improved.

Description

technical field [0001] The invention relates to a medical surgical instrument, in particular to a multifunctional temporary pacing electrode catheter. Background technique [0002] In recent years, the morbidity and mortality of heart disease have been increasing, and pacing catheters are needed to temporarily pace the heart in the treatment of various cardiovascular diseases. At present, the existing temporary pacing catheters on the market are basically divided into ordinary temporary pacing electrodes and floating temporary pacing electrodes. A floating temporary pacing lead floats from the peripheral vein to the right atrium and crosses the tricuspid valve by virtue of the buoyant force of the inflatable balloon at the distal end of the catheter, with or without fluoroscopic guidance (generally no fluoroscopic guidance is used). Push the catheter forward to the apex of the right ventricle; for a common temporary pacing lead, the surgeon pushes the catheter to the apex o...

AI Technical Summary

Problems solved by technology

At present, the two methods of placing pacing electrodes have single functions, and the operator needs to choose one of them according to the patient's indications, usage scenarios and other conditions, which cannot meet the diverse clinical needs at the same time.
