Embodiment Construction

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

[0021] The words expressing position and direction described in the present invention are all based on 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 wire protection device of the present invention is a flexible sleeve structure for covering the proximal end of the electrode wire. The protective device is composed of soft elastic materials, which are compatible with the physiological environment in the body and will not cause violent rejection of physiological tissues, including but not limited to ...

Abstract

The invention discloses an electrode lead protection device, which includes a clamping part and a surrounding part, the clamping part is solid, the clamping part is provided with a first limiting structure, and the surrounding part is extended from the clamping part Formed, the enclosing portion includes an accommodating cavity with an opening, and the enclosing portion is provided with a second limiting structure. The present invention designs a solid clamping part and the stopper on it to provide a clamping site for surgical auxiliary tools, and designs a hollow surrounding part to accommodate electrode wires, and at the same time designs a limiting structure in the surrounding part for surgical binding, thus protecting The electrode lead will not be damaged due to direct contact with auxiliary tools or surgical wires, and at the same time, the electrode lead connection end is protected from contamination when it passes through various subcutaneous channels or is implanted under the skin.

Description

Technical field [0001] The invention belongs to the technical field of implantable medical devices, and specifically relates to an electrode lead 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. It includes a pulse generator, an electrode lead and an extension lead connecting the two. The pulse generated by the pulse generator is transmitted to the electrode lead through the extension lead. During the process of implanting the electrode lead into the stimulation target area, its connection end with the extension lead is easily contaminated by blood or other substances in the body, which interferes with the transmission of pulse signals. Contamination mainly occurs in two situations: the electrode leads are contaminated when they pass through various internal channels; or, when the extension leads and pulse generator are temporarily not im...
