Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a DBS electrode lead subcutaneous traction protection device. Background Art

[0002] Functional neurosurgery has made great progress in recent years. The emergence of new surgical equipment has changed the treatment of functional diseases. Among them, the application of deep brain stimulation in the field of neurological and psychiatric diseases has been explored for more than ten diseases, including movement disorders (Parkinson's disease, dystonia and essential tremor), Tourette syndrome, pain, epilepsy, Alzheimer's disease, major depression, bipolar disorder, obsessive-compulsive disorder, anorexia nervosa. With the progress of society and the improvement of people's demand for quality of life, the number of DBS surgeries has increased year by year. The operating steps of DBS surgery are relatively complicated, among which the key is the precise implantation of electrodes and the connection of electrode wires with the extension wires of pulse generators.

[0003] After the electrode is implanted, the electrode wire needs to be fixed, and the scalp incision at the electrode implantation site needs to be sutured. The end of the electrode extension wire needs to be protected by an electrode cover and placed in a subcutaneous pouch behind the ear so that the pulse generator extension wire can be connected to the electrode wire at the incision behind the ear in the next step. This involves the electrode wire protection cover being led out to the incision behind the ear by subcutaneous traction after the skin behind the ear is incised, and then connected to the extension wire. In this process, because there are two electrode wires, it is necessary to distinguish the left and right sides of the electrode wire, and it is necessary to ensure that the electrode wire is not damaged. However, the current electrode wire protection cover is a single electrode wire protection, and the electrode wire protection covers on both sides need to be tied together by silk thread and implanted in a subcutaneous pouch. There is a risk of loose silk thread and fascia between the two protection covers, and then being blocked by fascia during traction. After the electrode wire is pulled to the incision behind the ear, it may be difficult to distinguish the left and right sides, which affects the progress of the operation to a certain extent and increases the complexity of the operation. Therefore, a person skilled in the art provides a DBS electrode wire subcutaneous traction protection device to solve the problems raised in the above background technology. Utility Model Content
