Problems solved by technology

[0004] However, the treatment electrodes currently used in clinical practice are all rigid metal electrodes. When treating deep tissues in the body, they often need to be inserted into very deep parts of the body, which brings discomfort to the patient.
In addition, for clinical treatment electrodes, some need to be implanted in the body for a long time, but due to corrosion, or the phenomenon of being wrapped by its own cells and tissues, the electrodes will need to be replaced regularly, causing the trouble of secondary surgery

Abstract

The invention provides an implantation-attachment type electrical stimulation device. The device comprises an implantation type electrode and an attachment type electrode. The implantation type electrode comprises a flexible packaging sleeve and liquid metal packaged therein. The attachment type electrode comprises an adherence sticker. A needle electrode which extends into the packaging sleeve is arranged on the adherence sticker. The attachment type electrode is connected with a package casing through a wire. A signal collecting unit, a controller and a power supply module are arranged in the package casing. The whole electrical stimulation device can well complete electrical stimulation treatment. The liquid metal in the implantation type electrode can be replaced through simple injection and aspiration. The implantation-attachment type electrical stimulation device is convenience for patients, and provides patients with a better treatment experience.

Description

technical field [0001] The invention belongs to the technical field of electrical stimulation equipment, and relates to an implant-attached electrical stimulation device. Background technique [0002] Low-frequency electrical stimulation is one of the commonly used treatment measures in the field of rehabilitation medicine. It uses pulse currents with a frequency below 1000Hz to treat patients to achieve the effect of improving patient function, relieving pain, and accelerating the process of disease recovery. At present, the types of electrical stimulation used for treatment mainly include constant direct current stimulation, pulse current, electric field and magnetic field, etc. [0003] For pain caused by acute diseases or traumatic injuries, electrical nerve stimulation has attracted the attention of doctors due to its better therapeutic effect, and it has brought new hope for pain relief to patients who still have no cure in clinical practice. In addition, Parkinson's ...
