Electrode guide wire shaping device of cardiac pacemaker

Abstract

The invention discloses an electrode guide wire shaping device of a cardiac pacemaker in the technical field of cardiac pacemaker implantation, and the electrode guide wire shaping device comprises a guide clamping seat, clamping columns, a clamping block and a lifting column, the vertical side wall is a cambered surface, and the multiple clamping columns are sequentially and uniformly arranged at the top of the guide clamping seat in an arc shape; the vertical side wall of one side of each clamping column protrudes out of the inner arc surface of the guide clamping seat, the electrode guide wire can be clamped at a specific angle through a specific shape, the electrode guide wire is drawn and shaped under the clamping of the specific radian, stable deformation at a set angle is formed, the radian of the guide clamping seat can be changed, and the clamping effect is good. Adjustment is carried out according to the size and the shape of a ventricular cavity of a patient, so that the shaping radian of the guide wire is changed, the deformation and the angle of the electrode guide wire are more suitable for the size, the angle and the like of the ventricular cavity of the corresponding patient, meanwhile, shaping of the electrode guide wire is more convenient, the shaping angle is more stable, and the success rate is higher.

Description

technical field [0001] The invention relates to the technical field of cardiac pacemaker implantation, in particular to an electrode guide wire shaping device of the cardiac pacemaker. Background technique [0002] A pacemaker is an electronic therapy device implanted in the body. The pulse generator emits electrical pulses powered by batteries, and through the conduction of the lead electrodes, it stimulates the myocardium in contact with the electrodes, and excites and contracts the heart, so as to achieve treatment. Cardiac dysfunction due to arrhythmias. [0003] The artificial cardiac pacing system mainly includes two parts: the pulse generator and the electrode guide wire. Pulse generators are often referred to alone as pacemakers. In addition to the above-mentioned pacing function, the pacing system also has the sensing function of returning the heart's own electrical activity to the pulse generator. The pacemaker is mainly composed of a power source (ie, a battery...

Problems solved by technology

At present, the shaping of the pacing electrode guide wire is done by the operator with bare hands in clinical practice. The straight guide wire is made into a certain bending shape according to his own experience, and after being placed in the right ventricle, it is withdrawn and reshaped according to the difference in the target site, or the guide wire is replaced. Reshaping, sometimes repeated several times still can not achieve the desired effect

Especially for some inexperienced operators, it is difficult to achieve reasonable shaping

This will increase the operation time, radiation dose and patient operation risk, and reduce the operation effect
