Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0021] The words expressing position and direction described in the present invention all refer to the pulse generator, the end close to the pulse generator is the proximal end, and the end far away from the pulse generator is the distal end.

[0022] The electrode lead protection device of the present invention is a flexible sleeve structure, which is used to cover the proximal end of the electrode lead. The protective device is made of soft elastic material, which is compatible with the physiological environment in the body and will not cause severe rejection of physiological tissues, including but n...

Abstract

Disclosed in the invention is an electrode lead protection device comprising a clamping part and an encircling part. The clamping part being solid is provided with a first limiting structure. The encircling part is formed by extending of the clamping part and contains an accommodation cavity having an opening; and the encircling part is provided with a second limiting structure. According to the invention, the solid clamping part and a limiting element arranged on the clamping part provide clamping points for an auxiliary operation tool and the hollow encircling part is designed to accommodate an electrode lead, and the limiting structure is designed for the encircling part to realize operation bundling, so that a phenomenon that the electrode lead is damaged due to direct contact with the auxiliary tool or an operation thread can be avoided. Besides, the electrode lead connecting end can be protected from being polluted when passing through various subcutaneous tunnels or in a subcutaneous implanting mode during the implanting process.

Description

technical field [0001] The invention belongs to the technical field of implantable medical devices, and in particular relates to an electrode wire protection device. Background technique [0002] The implantable electrical stimulation system is used to provide electrical stimulation to the stimulation target tissue in the patient's body, including a pulse generator, an electrode lead and an extension lead connecting the two, and the pulse generated by the pulse generator is transmitted to the electrode lead through the extension lead. During the process of implanting the electrode wire into the stimulation target area, the connection end of the electrode wire and the extension wire is easily polluted by blood or other substances in the body, thereby interfering with the transmission of the pulse signal. Contamination mainly occurs in two situations: when the lead is contaminated while passing through various passages in the body; or, when the extension lead and pulse generat...
