Abstract

The invention relates to the technical field of medical instruments, in particular to an implantable dual-channel extension lead for nerve stimulation. The implantable dual-channel extension lead for nerve stimulation comprises a catheter, wherein one end of the catheter is connected with a silica gel body, the other end of the catheter is sequentially provided with a connecting ring I, a connecting ring II, a connecting ring III, a connecting ring IV, a connecting ring V, a connecting ring VI, a connecting ring VII and a connecting ring VIII, the extension lead is divided into two connecting channels, the catheter is made of polyurethane materials, and a guide wire is a spiral wire formed by winding eight guide wire bodies, so that the strength of the extension lead can meet the requirement, the extension lead can be connected with two electrodes at the same time, the test treatment range is wide, and the requirements of complex illness conditions can be met.

Description

technical field [0001] The invention relates to an extension lead, in particular to an implantable nerve stimulation dual-channel extension lead. Background technique [0002] Deep brain stimulation therapy is mainly to implant a neurostimulator system into the patient's body, and use the neurostimulator to stimulate certain nerve nuclei in the deep part of the brain, correct abnormal brain electrical circuits, and relieve these neurological symptoms. Deep brain stimulation therapy can be used for neural regulation, and it cannot directly remove the lesion, but through external electrical stimulation to achieve the purpose of improving the patient's symptoms. [0003] Deep brain stimulation therapy uses stereotaxic methods to place electrodes in specific nuclei deep in the brain, and then uses extension wires to connect the electrodes implanted in the brain with the neurostimulator implanted in the subcutaneous area to improve patients with various diseases. An advanced tre...
