Description
First, technical field
The present invention relates to a kind of medical treatment device, more particularly to a kind of department of cardiac surgery pacemaker attachment means.
2nd, background technology
Cardiac operation is postoperative, especially the poor and postoperative patient of atrial fibrillation ablation of cardiac function, heart rate easily occurs slowly,
Serious Patient drug is difficult to lift heart rate, or even may result in patient acute congestive heart failure, threat to life occur.In order to ensure
The postoperative peri-operation period heart rate of patient is in safety range, and cardiac surgeon usually can be in operation process, in the heart of patient
Surface and skin surface respectively stitch a pin heart pacing electrode, once Heart Rate is partially slow, just can rise external for Pacing lead connection
Fight device, control the heart rate of patient, actively improve patient's rhythm of the heart, the generation of prevention of postoperative congestive heart failure.
Current traditional Pacing lead contact jaw is mainly helical plastic line or flexible metal seal wire.The former subject matter
It is that conductive contact area is less than normal, helical plastic line may be skidded off with the bounce of heart, causes loose contact, latter issues
Essentially consist in the bundles of wire guide of assembly more harder, bleeding risk height big to heart and injury, same easily because of the jump of heart
Move and skid off, cause loose contact.
In addition, the main method that traditional Pacing lead is fixed in heart surface is sewing, in the dirty ventricular muscles of pulsatile heart
On meat, suture Pacing lead and future have been pulled out bleeding risk, and suture bleeding can cause surgical hemostasises difficulty, extend handss
The art time；And removing after operation Pacing lead, more dangerous, easily cause former suture stomatorrhagia, pericardial tamponade, need emergency treatment pericardium
Puncture drainage, or even promptly open breast and detect, serious even occurs that heart failure causes death.
In recent years, heart mini-invasive incision operation popularization, case number of cases increases year by year, and traditional Pacing lead is solid using suture
Fixed, and most of Minimally Invasive Surgerys cannot expose ventricular muscles, can only expose relatively thin heart muscle, suture fixation cannot even more be applied to
The patient with operation of this type.Due to lacking the heart table Pacing lead of non-invasive, the control of heart rate after minimally invasive cardiac surgery operation operation in patients
System is even more an insoluble problem.
3rd, content of the invention
The present invention designs a kind of spring contact cardiac pacing leads for the deficiency of tradition Pacing lead at present, this
The difference of bright cardiac pacing leads and traditional Pacing lead is its contact jaw without being sewn to myocardial surface, but rely on from
The elasticity of body contact spring coil is directly contacted with heart surface, and its elastic dynamics will not oppress heart itself, spring coil sheet
Body can also be straightened, and visceral pericardium can be directly extracted out when taking out from pericardium.As the present invention need not be sutured in heart surface,
Operating time is not only effectively reduced, and has been greatly reduced the bleeding risk that places and take out process.
The preferred technical scheme that takes for realizing the above-mentioned purpose of the present invention is, a kind of spring contact cardiac pacing
Wire, between heart, skin and pacemaker, the wire includes：Spring wires portion, wire portion, puncture wire portion and the
One connecting portion；Wherein, spring wires portion is connected with wire portion by first connecting portion, the other end of wire portion and puncture wire portion
Connection.Wherein, spring wires portion is itself metal spring coil springy, and spring coil is helicon, using spring wire
The elastic force of circle itself and tension force, it is ensured that effectively contact heart surface.
Spring coil has certain elasticity and tension force in itself, when using as negative pole, it is ensured which can effectively contact heart table
Face, is close to heart surface by own tension, in addition the whole no rubber parcel of spring metal coil, it is ensured that its effective electric conductivity.
As spring coil is flexible metal, straighten can spring coil along Pacing lead longitudinal stretching, after facilitating Heart Rate to recover
Which is extracted out from pericardium.When using as positive pole, first angular pin end can be passed skin, and spring coil end is pulled to, stretch bullet
Spring coil, and the fixation that knots.Safety simple to operate.

5th, specific embodiment
Currently preferred one embodiment is located at the heart referring to Fig. 1, the spring contact cardiac pacing leads of the present embodiment
Between dirty, skin and pacemaker, the wire is divided into four parts：Spring wires portion 1；Wire portion 2, total length is 500 millimeters, directly
Footpath is 0.5 millimeter；Puncture wire portion 3 and first connecting portion 4.Wherein, spring wires portion 1 is by first connecting portion 4 and wire portion 2
Connection, the other end of wire portion 2 is connected with wire portion 3 is punctured.
As shown in Fig. 2 it is helicon that spring wires portion 1 is itself metal spring coil springy, spring coil.Closely
End surrounds a diameter of 5mm, and distal end surrounds a diameter of 10mm, and spring coil no stress is highly 5mm, metal spring coil itself
A diameter of 0.4mm.The present invention adopts the metal spring coil of soft texture as the contact jaw of Pacing lead, spring coil itself
There are certain elasticity and tension force, when using as negative pole, it is ensured which can effectively contact heart surface, be close to the heart by own tension
Dirty surface, the other whole no rubber parcel of spring metal coil, it is ensured that its effective electric conductivity.As spring coil is flexible gold
Category, straightens can spring coil along Pacing lead longitudinal stretching, facilitate Heart Rate after recovering to extract which from pericardium out.As
When positive pole is used, first angular pin end can be passed skin, spring coil end is pulled to, stretch spring coil, and the fixation that knots.Operation letter
