Active-fixation type pacemaker electrode lead and transmission device thereof

Abstract

The invention discloses an active-fixation type pacemaker electrode lead, comprising an internal insulating sleeve, an external insulating sleeve, a ring electrode and a soft-connection lapping rubbersleeve, wherein the external insulating sleeve, the ring electrode and the soft-connection lapping rubber sleeve are arranged on the internal insulating sleeve sequentially. Further, an external leadis arranged between the external insulating sleeve and the internal insulating sleeve, a ring electrode core touching the external lead is arranged between the external insulating sleeve and the internal insulating sleeve, and a part of the ring electrode core is disposed between the ring electrode and the internal insulating sleeve. An internal lead is arranged in the internal insulating sleeve,a spiral pipe with an internal spiral groove is arranged at the end of the internal insulating sleeve, an electrode tip outer pipe is arranged outside the spiral pipe, and a rotating shaft connectedwith the internal lead is arranged in the spiral pipe. The rotating shaft is provided with a pin arranged in the internal spiral groove of the spiral pipe, a seal ring and a drug suppository disposedat one end of the spiral pipe are arranged in the electrode tip outer pipe, the rotating shaft penetrates the seal ring and the drug suppository, and the penetrating end of the rotating shaft is connected with a spiral electrode tip. A spiral electrode tip liner and a mapping ring arranged at the end of the electrode tip outer pipe are disposed between the electrode tip outer pipe and the spiral electrode tip.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an active fixed pacemaker electrode lead and a transmission device for the electrode lead. Background technique [0002] The current active fixed pacemaker electrode leads, the electrode head is screwed in and out through the rotation of the shaft to drive the electrode head to rotate, and the rotation of the electrode head cooperates with the pin fixed on the outer tube of the electrode head to achieve the effect of screwing in and out, and then Can be actively fixed on the myocardium. However, this structure is prone to the following problems: 1. The rotation of the electrode head and the friction of the pin may easily cause damage to the surface coating of the electrode head, thereby affecting the performance of the electrode wire. 2 Due to the high precision of the electrode head and other parts, the processing is difficult, and the situation of screwing in and out i...

However, this structure is prone to the following problems: 1. The rotation of the electrode head and the friction of the pin can easily cause damage to the surface coating of the electrode head, thereby affecting the performance of the electrode wire

2 Due to the high precision of the electrode head and other parts, the processing is difficult, and the situation of screwing in and out is often unstable, which increases the difficulty of the operation

The current active fixed pacemaker electrode lead, the soft connection part is often bent under force during implantation, causing the inner insulating layer to press the inner lead, increasing the friction force, and causing the electrode head to be inflexible in screwing in and out, increasing the Difficulty of operation
