Problems solved by technology

[0003] During the implantation operation, the doctor first needs to determine the position of the target point in the patient's brain through a three-dimensional stereotaxic device. According to the position of the target point, the doctor makes a small hole on the patient's skull and inserts the electrode into the target point in the brain through the cranial hole. The doctor uses the test stimulator to test the implanted target. If the stimulation treatment effect is as expected, the electrode will be fixed on the skull after penetrating the electrode lock. The electrode lock is used to clamp the electrode, and the brain is often stimulated. , if the electrode for brain stimulation is slightly displaced, it may cause the stimulation to fail

Abstract

The invention discloses a skull hole electrode fixing device. A skull ring is fixed to a skull and comprises a ring part and an extending part, the extending part is connected to the bottom end of the ring part, a through hole is formed in the skull ring, at least part of an electrode lock is arranged in the through hole of the extending part, a clamping opening is formed in the electrode lock, and a locking assembly is arranged at the bottom end of the ring part and arranged on the outer side of the extending part in a sleeving mode. When the locking assembly moves from the first position to the second position, the locking assembly exerts acting force on the extending part, the opening in the bottom end of the through hole is shrunk and presses the electrode lock to lock the position and / or clamp the electrode, and when the locking assembly moves from the second position to the first position, the acting force of the locking assembly on the extending part disappears or is reduced. The opening in the bottom end of the through hole does not press the electrode lock, and position locking of the electrode lock is relieved or the electrode lock relieves the restraining effect on the electrode. The electrode lock is used for reducing position movement of the electrode lock, so that the problem of electrode stimulation failure is reduced, and the effectiveness of electrode stimulation is ensured.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a cranial hole electrode fixing device. Background technique [0002] Implantable medical systems usually include implantable electrical nerve stimulation systems, implantable cardiac electrical stimulation systems (commonly known as pacemakers), and implantable drug infusion systems. Among them, the implantable electrical nerve stimulation system includes a deep brain electrical stimulation system, an implantable cerebral cortex electrical stimulation system, an implantable spinal cord electrical stimulation system, an implantable sacral electrical nerve stimulation system, and an implantable vagus nerve electrical stimulation system. Taking the implantable electrical nerve stimulation system as an example, it mainly includes a pulse generator implanted in the body, electrodes and a control device outside the body. Among them, the pulse generator is connected to the ele...
