Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of to be implanted into automatic fixed plate-like head end ventricle through vein
Defibrillation pacing electrode wire.
Background technique
Existing implanted turn ventricular pacemaking defibrillation electrode conducting wire selected in multiple defibrillator installation art there is theoretical and
Problem of both technology.
It is mainly disadvantageous in that existing in terms of implantation theory, the selected structure through vein implantation defibrillation electrode conducting wire
Mode is similar to the head of pacing electrode wire, body, tail integration one-piece pattern structure, and defibrillation electrode is set to electrode cable
Body portion, shape is spirally to be wound in cylindrical type, rather than sheet defibrillation electrode.Corresponding is implanted into defibrillation through vein
Electrode cable implant surgery mode, including electrode cable head end implant site, electrode cable head end fixing means etc. cannot be done
To accurate selection, implant surgery perioperative complication of procedure and long term complication are not easily controlled.
It is mainly disadvantageous in that existing in terms of implanted prosthetics, defibrillation electrode conducting wire is conveyed from atrium dextrum through tricuspid valve
It is intracavitary to right ventricle, search out the gimmicks such as ideal implantation target area, readjustment and replacement implantation target area right ventricle is intracavitary
Operating process fully relies on the subjective thinking and experience accumulation of patient, without objective accurate localization method and corresponding assistor
Tool is precisely completed.As a result cause difference of technology level between ventricular defibrillation electrode conducting wire implant procedure patient very big, it is existing
Difference in terms of theory more has the difference in terms of personal operational capacity, and subjective part is relatively more anyway, can not be formulated to
The normalizing operation program of unified standard.
Manufactured and designed thinking by defibrillation electrode conducting wire overall structure and transportation system to be limited, most important problem is scarce
The softer ventricular defibrillation electrode conducting wire head end in body portion can conveniently, accurately, be quickly and safely transported to implantation target portion less
Position auxiliary duct road system, lack from external accurate manipulation enter the chambers of the heart after pacing electrode wire head end tool, lack
Pacing electrode wire head end can be just fixedly secured the fixation device in implantation target area in implantation less at once, lead to not reality
Now accurate, ventricular lead conducting wire implant surgery is rapidly completed in safety.It is embodied in:
(1) it cannot achieve the accurate super-selective defibrillation for being directed to left ventricle.
It is analyzed from the whole dissection structural point of heart, the chamber of heart can be divided into left and right atrium and Ventricular
Totally four chambers are analyzed from the physiological function angle of heart, it is most important that the function of ventricle, and left ventricle and right ventricle phase
Comparing, left ventricular function is more important, so, the heart function that we are usually said actually refers to the left heart in most cases
The function of room.When ventricular fibrillation occurs, Ventricular can all occur, and in contrast, the harm of left ventricle fibrillation is bigger, treatment
When theoretically should mainly for left ventricle carry out defibrillation.But under the conditions of our existing science and technology, implanted turns to remove again
It is intracavitary can only to be implanted to right ventricle for the head end of the ventricular defibrillation electrode conducting wire through vein implantation in the device that quivers installation art, and defibrillation is electric
Pole is intracavitary in the state that floats in right ventricle, can not accurately be fixed on a fixed position, can not be implanted in left ventricular cavity.With
For existing two kinds turn multiple defibrillation electrode conducting wire head end fixed mode through vein implanted, either passively head end is fixed still
Head end is actively fixed, the double helix approximate location of defibrillation electrode is almost the same, and one intracavitary positioned at right ventricle, another is located at upper
Vena cave.According to presetting or vitro program controlled, defibrillation electrode can be in the state of on or off in superior vena cava, so, it removes
The composition of electric field of quivering can be there are two types of main working method: between ventricular lead and ICD casing, between two screw electrodes.
Both working methods are formed by field regime and compare, what the electric field formed between ventricular lead and ICD casing was covered
Left ventricle range is more targeted, but does not absolutely accomplish accurately to be directed to left ventricle electric discharge, because screw electrode is intracavitary in right ventricle
Float position situation is different, while it is uncertain to cover right ventricular volume range, so defibrillation accurately cannot be carried out for left ventricle,
It is too small additionally, due to screw electrode area, realize that safe defibrillation institute electricity demand is larger.The electric field formed between double spiral electrode, institute
The range covered is then far longer than left ventricle, four chambers of entire heart is even generally covered, so nor needle
To the accurate defibrillation of left ventricle.
(2) large area sheet defibrillation electrode can not be implanted in the chambers of the heart.
The size of external electric defibrillation, electrode plate has an important influence defibrillation success rate, for adult, the electrode of 12cm
Plate defibrillation success rate is higher than the electrode plate of 8cm；The large electrode plate of the small electrode plate ratio 8cm or 12cm of 4.3cm obviously increases cardiac muscle
Damage；As a same reason, the area of internal defibrillation, defibrillation electrode is also extremely important.
Only in current scientific and technical situation, slabbing can't be done through the defibrillation electrode shape in the vein implantation chambers of the heart
Electrode can only be made into existing zigzag shape electrode, so defibrillation electrode area very little.The surface area of screw electrode circumference is about
For (3.2*3.14*50=251mm2), effective participation area when constructing defibrillation electric field between counter electrode is up to it
The half of the gross area, about 125mm2.Compared with the sheet defibrillation electrode (13*13cm2 rectangle 169cm2) of external defibrillation
Compared with, or compared with intrathoracic direct defibrillation electrode spoon (diameter 8cm disc-shaped 50cm2), the area of helical form wire-type of electrode is bright
Aobvious very little, it is unhorizontal in the same order of magnitude.
The defibrillation electrode of small area was selected to carry out defibrillation to the ventricle of huge area, institute's electricity demand naturally can be bigger,
Because only that meeting the electricity using minimum Defibrillator threshold, it can ensure effective defibrillation to entire ventricle.Due to helical form
The area of electrode (wire electrode) is too small, between either two screw electrodes (wire electrode) or a screw electrode (line
Shape electrode) and ICD casing (pellet electrode) between, require biggish electricity, single defibrillation institute electricity demand minimum value has been at present
Close to 20J.
The big consequence of electricity, on the one hand, defibrillator battery service life can shorten, and on the other hand, when defibrillation makes patient
At damage can be bigger, the pain that patient experiences also can be bigger.
(3) it cannot achieve the position of precisely implantation defibrillation electrode
It is existing to be implanted into defibrillation electrode conducting wire implanted prosthetics operating method and available tool and pacing electrode wire through vein
Implanted prosthetics is identical, has certain defect, when defibrillation electrode conducting wire enters superior vena cava or atrium dextrum from short sheath
Top and then the sheath conveying device without fettering and limiting the traveling in the chambers of the heart of defibrillation electrode conducting wire head end, more do not take aim at
Quasi- measure, the subsequent process that defibrillation electrode conducting wire head end is implanted to target spot fully rely on the artificial manipulation of patient and come in fact
It is existing.And the tool that patient is able to use, the only guide wire through electrode cable center cavity, shortage can accurately manipulate and
Limit the objective auxiliary tool or special equipment of defibrillation electrode conducting wire head end.Although existing actively fix head end ventricular defibrillation
Electrode cable can be implanted in the intracavitary any position of right ventricle in principle, but generally be implanted into the selection of target spot or random,
Ventricular pacemaking defibrillation electrode conducting wire head end is implanted in some privileged site of ventricular muscles in which cannot accomplish super-selective.Electrode
Conducting wire head-end location can not be selected accurately, and the defibrillation electrode positioned at body portion can not accurately be determined in the intracavitary location of right ventricle
Position, moreover, electrode cable must keep lower tension state in the chambers of the heart, is just unlikely to be pulled displacement, so, at certain
In degree, ventricular defibrillation electrode is intracavitary in the state that floats in right ventricle.
(4) it cannot achieve effective fixation of ventricular defibrillation electrode conducting wire head end.
Multiple defibrillator implant surgery is turned using the implanted that existing ventricular defibrillation electrode conducting wire is completed, if implantation be by
Dynamic fixed head end defibrillation electrode conducting wire, being implanted into fixation principle at once is the inverted beard and ventricular muscles by defibrillation electrode conducting wire head end
Temporary containing between the trabecular muscles network of convex-concave surface cannot achieve high-intensitive effective fixation, generally require on patient bed
Braking will also limit the normal activity of art side upper limb in three days, one month.If implantation is actively to fix head end defibrillation electrode to lead
Line, being implanted into fixation principle at once is that the screw screwed out by defibrillation electrode conducting wire head end is fixed in ventricular muscles, general unlikely
In falling off easily, but since the volume of screw geometry and restrained cardiac muscular tissue is limited, fixed and insecure, patient encloses art
Phase also has to avoid the normal activity of art side limbs.Both modes to the fixing intensity of defibrillation electrode conducting wire head end all very
Weak, either implant surgery is at once or at a specified future date, has the problem of dislocation or micro- dislocation (poor contact), is likely to cause
ICD perception and defibrillating function obstacle.
(5) the surgical procedures complication such as diaphram, diaphragm nerve stimulation, cardiac perforation, dislocation of electrode is not can avoid.
Multiple defibrillator implant surgery is turned using the implanted that existing ventricular defibrillation electrode conducting wire is completed, what is no matter be implanted into is
Passive fixed head end defibrillation electrode conducting wire, or head end defibrillation electrode conducting wire is actively fixed, body portion can be compared due to lacking
Soft ventricular defibrillation electrode conducting wire facilitates, is accurate, being safely transported to ideal target area and the auxiliary being fixedly secured at once is defeated
Pipe-line system and control device are sent, selecting, which not can avoid when target area, touches free ventricular wall, not can avoid diaphram diaphragm naturally
Nerve stimulation complication；Due to lack from external accurate manipulation enter the chambers of the heart after defibrillation electrode conducting wire head end specialist tools,
The unique method for pushing the electrode cable of body portion softness is the guide wire intracavitary by central control post, and dynamics grasp is bad, and have can
Free ventricular wall can be caused to perforate；It is being implanted into due to lacking for defibrillation electrode conducting wire head end to be fixedly secured at once in implantation
The device of target area, it is postoperative it is inevitable poor contact between recent and electrode head end at a specified future date and cardiac muscular tissue occurs, cause electrode de-
Position, micro- dislocation risk.
(6) electrode cable diameter problems of too can not be solved
Existing ventricular defibrillation electrode diameter of wire least limit is 3.2mm, when intravenously implantation is more simultaneously for same root approach
When with electrode cable, the occupation time process to approach vein lumen is inevitably caused, machine and cicatrization serious person is especially encountered, adds
The factors such as upper induction thrombosis, it is difficult to avoid impacting approach venous blood flow；Electrode cable diameter is bigger, is passing through lock
It is easier when under bone at the first rib interval to be pressed by card, it is even worn, destroys；Once meeting with, electrode cable is damaged, feels
Dye, when needing to pull out electrode cable, excessive machine is often resulted between electrode cable and wall of vein or is glued between right atrium wall
It is even serious, hence it is evident that increase difficulty and risk that electrode cable is pulled out.
(7) assure success defibrillation and single defibrillation quantity problem
The treatment function of ICD processing ventricular arrhythmia mainly includes that anti-tachyarrhythmia pacemaker (ATP), low energy synchronize electricity
Turn multiple, three kinds of modes of high-energy defibrillation.
Anti-tachyarrhythmia pacemaker (ATP)
Anti-tachyarrhythmia pacemaker terminates the total success rate of ventricular tachycardia and is up to 91%, and nonresponder 6%, deteriorate this 3%.Due to its hair
Putting is low voltage pulse stimulation, and patient is low additionally, due to its power consumption without sense of discomfort, the referred to as nonpain treatment of ICD, so energy
Extend ICD battery.
Low energy synchronizes electrical conversion
The synchronous electrical conversion of low energy is mainly used for terminating ventricular tachycardia, and ICD low energy electrical conversion treats the advantage of ventricular tachycardia, treatment hair
Fast (charging time is short) put, energy content of battery consumption is low, and patient's sense of discomfort is few.Everyone pain threshold is different in clinic, absolutely
Most patients can only receive≤electric discharge of 1J without with apparent pain, so, the energy range setting of low energy electrical conversion
For 0.4~2J.
High-energy defibrillation
High-energy defibrillation is treatment means most strong and last in icd system.The mechanism of defibrillation therapy, 1. critical mass is managed
By: defibrillation can eliminate the wave crest near electrode when discharging, but the exciting wave crest at other positions can continue in electrode distant place
Low-voltage region in expand cloth.When the ventricular muscles region of these exciting wave crest controls is greater than the cardiac muscle of critical mass, then ventricular fibrillation exists
Continue to expand cloth without terminating in other positions of ventricular muscles.2. rapid wear upper-bound theory: electric discharge when defibrillation can make the excitement of all cardiac muscles
It is all off, but if defibrillation wave falls in one or more myocardial regions for vulnerable period, ventricular fibrillation can be induced again.Because
Always there are a certain number of cardiac muscles in vulnerable period.Therefore, the intensity of successful defibrillation electric discharge not only wants that overlooking quality can be made
Myocardium depolarization is also greater than all total amounts in vulnerable period position cardiac muscle.
It is generally acknowledged that the discharge energy of 2~5J or more belongs to high-energy defibrillation.ICD defibrillation safe range refers to icd system
Highest defibrillation energy be higher than the difference of Defibrillator threshold measured in art.Under normal circumstances, which should be greater than 8-10J.
General maximum discharge power is up to 34J.
With the increase of defibrillation energy, a possibility that successful defibrillation, increases, while causing the probability of myocardial cell injury
Increase.Power consumption increases, and battery decline, patient's sense of discomfort increases, and pain increases.
