Abstract

The utility model discloses a kind of plug-ins without electrode of transferring, belong to medical instruments field, it includes the electrode proximal end for connecting stimulator and the electrode distal end for being inserted into head, and a transfer block is arranged between electrode proximal end and electrode distal end, and transfer block has Y type confluence passage；Y type confluence passage includes the first passage and the second channel passed through for stylet that power pole passes through, and first passage and second channel converge at confluence passage.Between electrode proximal end and electrode distal end plus a transfer block, a channel of transfer block provide electrode distal end and connect with electrode proximal end, another channel provides stylet insertion.When specific operation, since Intracranical deep electrode is multi-channel testing, so conducting wire is rope-lay strand, since conducting wire is thinner, cause electrode tube extremely soft, is passed through using stylet from second channel, it realizes that electrode distal end is inserted into using the hardness of stylet, after electrode is installed, stylet is extracted.

Description

A kind of plug-in is without electrode of transferring

Technical field

The utility model relates to medical instruments fields, specifically, being related to a kind of plug-in without electrode of transferring.

Background technique

Intracranial electrode is a kind of multifinger electrode of special substance, its biggest advantage is that cortex can be recorded directly Electrical activity, and encephalic can be temporarily implanted.Intracranial electrode can be generally divided into depth electrode, Subdural space strip shaped electric poles and grid Shape cortical electrode.Scalp, cranium can be excluded to the maximum extent using the electrocorticogram or depth electroencephalogram of intracranial recording electrode The influence that the structures such as bone, endocranium record electrical activity of brain；And to surrounding or at a distance, conduction expands cloth to judgement hair to electrical activity of brain Make the influence to originate from.When epileptogenic focus is located near the critical functions areas such as movement, language, skin can also be carried out using intracranial electrode Layer electro photoluminescence drawing, the exact position in positioning function area.

It is discharged with brain depth electrode from epileptic patient deep-brain record epileptic focus source, starts from Hahge Belinson With the Gibbs epoch.The use of the long-range eeg recording of multi-joint intracerebral or depth electrode technology and bilateral temporal lobe epileptic focus promotes Clinical research develops in depth.Patient needs encephalic electroencephalogram (EEG) to record, accurately to diagnose and design therapeutic surgery hand Art step.Thus oneself is in the more epilepsy diagnosis and treatment center applications in countries in the world, oneself become determine the most common method in epileptic focus source it One.

Depth electrode is usually divided to two types: 1. hard electrode is said in a way, disposes hard electrode can be more in cortex It is accurate.But electrode moves in brain tissue, is easy to damage brain tissue or the cerebrovascular.

2. elastic electrode.It is flexible, hard, how much different contact number is, is made of different metals, from different Approach insertion, and can be applied in long or short term in operating room.The tip of electrode is more blunt, so as to avoid in insertion process The middle holy tissue of detachment nerve.Most surgeons like flexible electrode, because it is than hard electrode safety.It will be semirigid Stylet or propeller are placed in the hollow core position of thimble tube electrode or place along conducting wire, are inserted into elastic electrode with it. After inserting electrodes into, stylet or propeller are just removed, elastic electrode is waited behind.For elastic electrode, head When catching a packet, electrode can not be caused to move in brain tissue and cause to damage.When not needed, it can be removed easily in bedside Electrode is walked, and almost without uncomfortable feeling.

To guarantee to bring the smallest wound and pain to patient, the outer diameter of Intracranical deep electrode is all minimum, wall thickness pole Thin, between 0.1-0.2mm range, it is extremely soft that thin-wall construction results in electrode tube, and is easy breakage.Intracranical deep electrode is multi-pass Road monitoring, if wherein there is multiple conducting wires damaged, extremely occurs short circuit, causes unnecessary loss so conducting wire is rope-lay strand.? In production, since multi cord twists together, it is difficult to distinguish and chooses.

Utility model content

The purpose of this utility model is to provide a kind of plug-in without electrode of transferring, and has both been able to satisfy hollow structure supply pipe Core needle insertion, and can directly plug, and be not necessarily to other adapters, reduce doctor workload and to product using grasp when Between.

To achieve the goals above, plug-in provided by the utility model includes for connecting stimulator without electrode of transferring Electrode proximal end and electrode distal end for being inserted into head, a transfer block is arranged between electrode proximal end and electrode distal end, should Transfer block has a Y type confluence passage；Y type confluence passage include the first passage that power pole passes through and pass through for stylet Two channels, first passage and second channel converge at confluence passage.

In above-mentioned technical proposal, a transfer block, a channel of transfer block are added between electrode proximal end and electrode distal end It provides electrode distal end to connect with electrode proximal end, another channel provides stylet insertion.Electrode proximal end is connected with stimulator, electrode Distal end insertion head, when specific operation, since Intracranical deep electrode is multi-channel testing, so conducting wire is rope-lay strand, due to Conducting wire is thinner, causes electrode tube extremely soft, is passed through using stylet from second channel, realizes electrode using the hardness of stylet Distal end is inserted into, and after electrode is installed, stylet is extracted.

Specific scheme is that electrode proximal end is fabricated to the solid bar with rigidity.Make its intensity enough with plug-in stimulator Connection.

Another specific scheme is the hose that confluence passage is extended with one for accommodate electrod distal end.The hose will own Electrode cable cladding is got up, the support convenient for stylet to electrode cable.

More specific scheme is that the axis of second channel is overlapped with the axis of confluence passage.To prevent stylet in insertion hose During occur bending and deformation.

Another specific scheme is that the two sides of transfer block are equipped with fixed ear.For transfer block to be fixed.

Another specific scheme is that fixed ear is equipped with the through-hole for being used for mounting screw.

Compared with prior art, the utility model has the following beneficial effects:

The plug-in of the utility model had not only been able to satisfy hollow structure supply stylet insertion without electrode of transferring, but also can be straight It patches and pulls out, be not necessarily to other adapters, reduce the workload of doctor and reduce the time to product using grasp.
