Description
Technical field
The utility model relates to the field of medical instrument technology, specifically, being a kind of pulmonary valve expansion device.
Background technique
In patients with congenital heart, with the presence of the locking of a kind of pulmonary valve or the infant of Serious Stenosis, because it goes out
Occur severe hypoxia threat to life at once after life and usually needs to carry out emergent management in neonatal period.However due to the age is small,
Weight is low, and big by traditional lower incision of extracorporal circulatory system auxiliary operation direct-view or expansion pulmonary valve wound, infant is often difficult to
Tolerance operation strike causes the death rate higher.It, directly will be straight after the total arteriotomy of lung if not using extracorporal circulatory system to be assisted
Depending on lower operation then often due to moment amount of bleeding is big and causes the unstable or even threat to life of the serious circulation of infant.Carry out tradition
Transcathether interventional procedure need RF ablation or balloon expandable from the femoral vein vascular puncture of thigh root and by conduit
Device is sent to the corresponding position of pulmonary valve at the top of right ventricular outflow and is handled.Firstly, the infant of low age, under-weight due to
Femoral vein blood pipe diameter very little, the diameter of catheter delivery device are very restricted；In addition implemented in interposing catheter treatment
It, can not be bright by radiography for the patient of pulmonary atresia because without blood flow pulmonary artery can be entered from right ventricle in journey
The true corresponding position of pulmonary valve may cause cardiac perforation rupture to the RF ablation that the pulmonary artery of film property locking carries out blindness
Serious risk, certainly for flesh locking unlikely handled by traditional interventional therapy means.
In view of traditional surgery and traditional interventional therapy means for processing pulmonary atresia and Serious Stenosis
All there is respective obvious shortcoming, therefore the thinking of Medicine and Surgery Hybrid therapy is come into being.So-called Hybrid therapy is in surgery hand
It is treated while art is treated or successively in conjunction with interventional method.For the Hybrid therapy of pulmonary atresia or Serious Stenosis infant
Process is to be completed to open chest by cardiac surgeon after anaesthetizing, and the device of interventional therapy is directly sent by right ventricle or the total artery of lung
Carry out the needle thorn or expansion of pulmonary artery.Device used in art is ordinary venous puncture needle, guiding steel wire, inflatable expansion at present
Sacculus.Direct needle thorn either still has syringe needle to accidentally injure cardiac structure or pulmonary artery from right ventricle approach from pulmonary artery approach
The risk of wall, and need successively to carry out by the pocket that sews in advance needle thorn, be sent into guide wire, the withdraw of the needle, be sent into it is expansible
Sacculus, which is inflated, expands these steps, probably due to cumbersome, step more causes device to slip and needs again again
The possibility of operation.
Extracorporal circulatory system assists menisectomy wound big, be easy to cause neonatal lung and anasarca, inflammatory mediator release etc.
Complication causes post-operative recovery difficult.The total arteriotomy of lung is carried out under O ff-pump auxiliary to look at lower pulmonary valve incision straight
And/or dilatation causes moment amount of bleeding big, be easy to cause infant circulation unstability or even direct threat to life.Tradition intervention is controlled
The treatment means newborn small for weight is limited by femoral vein blood pipe diameter, conveys RF ablation or balloon expandable device is tired
It is difficult.The positioning of pulmonary valve has difficulties in right ventricle, and the RF ablation of blindness may cause the severe complication of cardiac rupture,
For the flesh pulmonary atresia of narrow segment length, it is even more impossible to handle.
Hybrid therapy is the mode that current processing neonatal pulmonary is latched or Serious Stenosis is relatively good, but currently without spy
Fixed processing unit.More, the operation using traditional needle thorn, feeding guiding steel wire, the withdraw of the needle, feeding inflating balloon progress expansion step
It is cumbersome, however it remains syringe needle accidentally injures risk or guiding steel wire and falls off the possibility that need to be re-operated again.Therefore designing one kind can
The Hybrid therapy device for allowing surgeon to be sent into pulmonary valve corresponding position safely, can reliably expand by being once sent into completion
Just become urgent problem to be solved.
