Embodiment Construction

[0031] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0032] refer to Figure 1 to Figure 4 , a brain electrode wire fixation auxiliary device 10, comprising an auxiliary device body 20, the lower end of the auxiliary device body 20 extends downward to form a cranial hole plug pressing part 30 extending out of the auxiliary device body 20, the cranial The hole plug depressing part 30 cooperates with the upper surface of the cranial hole plug 40 for plugging the cranial hole plug 40 into the hole of the skull ring 50 .

[0033] The auxiliary device body 20 is provided with a groove 201 penetrating through the pressing portion 30 of the cranial hole plug, and one end of the groove 201 extends to the edge of the auxiliary device body 20 . In this embodiment, the groove 201 is a linear groove, and in some other embodiments, the groove 201 may also be a curved groove or a cross-line groove.

[0034] The outer surface of the...

Abstract

The invention discloses a fixation aid for a brain electrode lead, which comprises an aid body. The lower end of the aid body extends downwards to form a cranial hole plug press-down part extending out of the aid body, and the cranial hole plug press-down part is matched with the upper surface of a cranial hole plug to insert the cranial hole plug into a hole of a cranial ring. Compared with the prior art, the fixation aid for the brain electrode lead has the advantages that a surgeon can reliably push down and fasten the cranial hole plug into the cranial ring in a narrow space during a surgery; when the electrode lead reaches an assigned target by the aid of a lead needle, the surgeon can pull out the lead needle, and accordingly the cranial hole plug immediately holds the electrode lead to avoid horizontal and vertical displacement of the electrode lead, the electrode lead is firmly and accurately positioned at the assigned target position, target shift is avoided when the surgeon closes the cranial ring, and the whole surgical operation is convenient.

Description

technical field [0001] The invention relates to the field of implantable medical systems, in particular to a fixation auxiliary device for fixing brain electrode wires or other catheters on the skull during the implantation operation of the implantable medical system. Background technique [0002] Implantable medical systems usually include implantable nerve electrical stimulation systems, implantable cardiac electrical stimulation systems (commonly known as cardiac pacemakers), and implantable drug infusion systems. Among them, implantable electrical nerve stimulation systems include deep brain electrical stimulation DBS, implantable cerebral cortex electrical stimulation CNS, implantable spinal cord electrical stimulation SCS, implantable sacral nerve electrical stimulation SNS, implantable vagus nerve electrical stimulation VNS, etc. [0003] Taking the implanted electrical nerve stimulation system as an example, it mainly includes a pulse generator implanted in the body,...
