Problems solved by technology

During the above-mentioned rotation operation, since the finger acts on the position of the force point 7 when rotating the rotation clamp 4, and this position is relatively far away from the connecting needle 2, the rotation operation is very inconvenient, and each time the rotation clamp 4 is turned, only 4 The connection needle 2 can be rotated once, and it takes a long time to unscrew the spiral electrode 3 completely, which increases the operation time and the risk of infection for the patient

Embodiment Construction

[0029] The active electrode rotation device proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that the drawings are all in a very simplified form and use imprecise ratios, which are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0030] The core idea of ​​the present invention is to provide an active electrode rotation device, which connects the connecting end with the connecting pin of the active electrode, so that the operator can rotate the handle end by rotating the knob to drive the connecting end and the connecting pin to rotate , so that the spiral electrode can be pulled out of the active electrode smoothly, while increasing the accuracy of the operator's operation, it reduces the ...

Abstract

The invention provides an active electrode rotating device, which connects the connecting end of the active electrode to the connecting pin, so that the operator can rotate the handle end by rotating the knob to drive the connecting end and the connecting pin to rotate, so that the spiral electrode The active electrode can be pulled out smoothly, which not only increases the operator's operation accuracy, but also reduces the time required for the operation and the risk of infection for the patient. At the same time, because the handle end and the connection end have through holes for the operation guide wire to pass through, Therefore, the installation and operation of the active electrode rotating device will not affect the guidance of the operation guide wire, so that the operation can be carried out smoothly.

Description

technical field [0001] The invention relates to an auxiliary tool applied to the implantation of implantable cardiac pacemaker electrodes, in particular to an active electrode rotating device. Background technique [0002] Active helical electrode wires currently used in the treatment of cardiac rhythm disorders have been widely used clinically, such as figure 1 As shown, the distal end (the end away from the operator) of the existing active helical electrode wire has a retractable helical electrode 3, and the operator can rotate the connecting needle located at the proximal end of the active helical electrode wire (the end near the operator) 2. Screw the spiral electrode 3 into the myocardium and then fix it in the heart, so as to realize the mechanical and electronic connection between the spiral electrode 3 and the myocardium. Such as figure 2 As shown, the existing method of rotating the proximal connecting needle 2 is to first connect the rotating clamp 4 to the conn...
