Abstract
The utility model relates to an intracranial deep electrode which is composed of an insulated tubular carrier, a plurality of sub electrodes inlaid on the carrier and an insulated conductor in the carrier, wherein both ends of the insulated conductor are respectively connected with the sub electrodes. The carrier is made of soft insulating materials. An elastic core in the tube direction is arranged in the carrier, corresponding to the sub electrode section, so the front part of the electrode, inlaid with the sub electrodes, has a certain hardness so as to automatically enter the intracranial deep part with high positioning accuracy, has no need of opening a cranium for placement, relieves patients' pain and can automatically recover bending and other deformation generated after preoperative disinfection. The back part of the electrode keeping the soft state can be easily fixed on the head, can not shake or easily fall off with state recorded wave shape and can be used for preoperative detection and monitoring during operations to provide reliable assurance for successful operations.
Description
Technical field
This utility model relates to a kind of electrode that is used for sensing, the biological electric wave of record intracranial, and particularly a kind of intracranial depth electrode belongs to medical apparatus and instruments.
Background technology
At present, before the art of epileptic patient being carried out operation of opening cranium and in the art, need a kind of electrode that is used for sensing, the biological electric wave of record intracranial that can enter the intracranial deep.The applicant once designed a kind of by insulating tubular type carrier, be embedded in a plurality of electrode on the carrier, be positioned at carrier and the two ends intracranial depth electrode formed of the insulated conductor of connection electrode and monitor respectively.But, because below, kind electrode can not enter clinical practice so far: if this electrode integral body is harder, though enter intracranial easily, be difficult to fix, can produce shake, easily come off, wave recording can change unusually; If this electrode integral body is soft, though be easy to fix, be difficult to enter intracranial, and the deformation such as bending that the sterilization back produces before the art can not recover voluntarily.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the shortcoming that above-mentioned electrode exists, and a kind of intracranial that both had been easy to enter is provided, and is convenient to fixed intracranial depth electrode again.
The technical scheme that its technical problem that solves this utility model adopts is as follows: a kind of intracranial depth electrode, by insulating tubular type carrier, be embedded in a plurality of electrode on the carrier, be positioned at carrier and two ends respectively the insulated conductor of connection electrode and monitor form, it is characterized in that carrier is made of softish insulant, in carrier, have the pipe corresponding with the electrode sub-segments to elastic core element.
The beneficial effects of the utility model are as follows: since carrier in have pipe to elastic core element, the front portion that makes this electrode be embedded with electrode has certain rigidity, be easy to from being advanced into the intracranial deep, the positional accuracy height, need not out cranium places, alleviate patient's misery, and the deformation such as bending that the sterilization back produces before the art can recover voluntarily.Because this electrode rear portion keeps soft condition, is easy to fix at head, can not produce shake, difficult drop-off, wave recording is stable, guards in detection and the art before the available Rhizoma Atractylodis Macrocephalae, and reliable assurance is provided smoothly for performing the operation.
Description of drawings
Fig. 1 is this utility model intracranial depth electrode structure cut-away view.
The specific embodiment
With reference to the accompanying drawings and in conjunction with the embodiments this utility model is described in detail.
As shown in Figure 1, this utility model intracranial depth electrode by insulating tubular type carrier 3, be embedded in a plurality of electrode 2 on the carrier, be arranged in carrier and two ends respectively the insulated conductor 1 of connection electrode son 2 and monitor (figure does not draw) form, carrier 3 is made of softish insulant such as medical silica-gel, in carrier 3, also have the pipe corresponding with electrode 2 place sections to elastic core element 4.Elastic core element can be with metal material or carbon materials manufacturing.
In embodiment as shown in the figure, the further feature of this utility model is: 1, be injected with the silica gel liquid of medical normal temperature cure in the electrode holder, make electrode keep whole stability; 2, the electrode front end glueds joint termination 5, makes the easier intracranial that enters of electrode; 3, have in the electrode holder rear portion pipe to medical stainless steel silk core body 6, make electrode rear portion pliability moderate, also have certain elasticity, use more conveniently, further improve its value for clinical application.
Claims (4)
1, intracranial depth electrode, by insulating tubular type carrier, be embedded in a plurality of electrode on the carrier, be positioned at carrier and two ends respectively the insulated conductor of connection electrode and monitor form, it is characterized in that carrier is made of softish insulant, in carrier, have the pipe corresponding with the electrode sub-segments to elastic core element.
2, intracranial depth electrode according to claim 1 is characterized in that being injected with the silica gel liquid of medical normal temperature cure in described carrier.
3, intracranial depth electrode according to claim 1 is characterized in that the splicing of electrode front end has the termination.
