A device for evaluating the position of a test stimulating electrode

Abstract

The invention relates to a position evaluation apparatus of testing a stimulation electrode. The position evaluation apparatus is an electric pulse stimulation test apparatus and the apparatus comprises an external program control instrument and a test lead. The external program control instrument comprises a pulse generation module used for generating an electrical stimulation pulse signal. The test lead is used for connecting the external program control instrument to a stimulation electrode. The external program control instrument also comprises an electrophysiological signal acquisition module, a storage module and an electrophysiological signal comparison module, wherein the electrophysiological signal acquisition module is used for controlling the stimulation electrode so as to collect electrophysiological signals of a human body; the storage module is used for storing the electrophysiological signals collected by the electrophysiological signal acquisition module; the electrophysiological signal comparison module is used for comparing the different electrophysiological signals. By using the position evaluation apparatus of testing the stimulation electrode, during an operation process, a position offset condition of the stimulation electrode before and after being fixed can be timely and effectively evaluated and tested.

Description

technical field [0001] The invention belongs to the field of micro medical instruments, in particular to a method and a device for timely and effectively evaluating the position change of a test stimulation electrode during an operation. Background technique [0002] There are many types of implantable medical devices, such as pacemakers, defibrillators, deep brain stimulators, spinal cord stimulators, vagus nerve stimulators, gastrointestinal stimulators, muscle stimulators, peripheral nerve stimulators, or other similar stimulators Wait. Implantable medical devices generally include implanted stimulating electrodes in the body and external control devices, which exchange information through two-way wireless communication. [0003] When implantable medical devices are used, stimulating electrodes are implanted in the body. Taking the deep brain stimulator as an example, the surgical process of implanting stimulating electrodes into the brain usually includes the following...

[0004] However, MRI scanning not only increases the cost and time of treatment for patients, but also poses certain risks to patients

In addition, if it is found that the final position of the stimulation contact point of the stimulation electrode deviates too much from the target position, a new operation is required, which undoubtedly brings greater pain to the patient.
