Embodiment Construction

[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0022] Such as figure 1 , figure 2 and image 3 As shown, the implantable nerve stimulator electrode contact structure of the present invention mainly includes a platinum-iridium alloy wire made of a platinum-iridium alloy spiral 1 . Wherein, one end of the platinum-iridium alloy helix 1 is fixedly connected with a small helix 6 to form an electrode for transmitting electrical stimulation signals. Of course, the platinum-iridium alloy helix 1 and the small helix 6 can be connected by pressing or welding and covered with a protective capillary (not shown in the figure). The capillary mentioned above is an existing conventional structure, so it will not be described in detail. In addition, the connecting portion of the platinum-iridium alloy ...

Abstract

The invention discloses an implantable nerve stimulator electrode contact structure. It includes a platinum-iridium alloy wire made of a platinum-iridium alloy helix, one end of the platinum-iridium alloy helix is ​​fixedly connected to a small helix to form an electrode for transmitting electrical stimulation signals, and the connection between the platinum-iridium alloy helix and the small helix is ​​covered with silica gel. It is covered with a butterfly wing-shaped fixing part; the other end of the platinum-iridium alloy helix is ​​connected with a medical suture thread with a medical suture needle for easy connection and fixation with the stimulated site. After the structure is adopted, the connection between the platinum-iridium alloy helix and the small helix enables it to have sufficient connection strength and can stably transmit electrical stimulation signals. In addition, with this structure, the platinum-iridium alloy spiral contact can also be connected to the stimulated part such as the stomach, colon or heart, and the stimulated part can not be separated when the stimulated part wriggles, and the electrical stimulation signal can be stably transmitted.

Description

Technical field: [0001] The invention relates to the field of medical equipment, in particular to an electrode contact structure of an implanted nerve stimulator. Background technique: [0002] Existing medical nerve stimulators, such as gastric electric stimulators, colon electric stimulators, and cardiac electric stimulators, usually directly use platinum-iridium alloy sheets or columns as electrode contacts. This scheme has the following disadvantages: [0003] 1. The platinum-iridium alloy sheet or column is not soft enough, and the contact with the implanted tissue is not close enough. [0004] 2. The contact fixation between the platinum-iridium alloy sheet or column and the implanted human tissue is difficult or not reliable enough. [0005] 3. The contact between the platinum-iridium alloy wire and the implanted human tissue is insufficient. The platinum-iridium spiral contact is made of multiple strands wound in parallel to avoid electrical signal interruption af...
