Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to what a kind of band punctured function intervenes delivery system through atrial septum
System.
Background technique
Congenital heart disease is most common one kind in congenital abnormality, accounts for about the 28% of various congenital malformations, refers in embryo
Tire developmental stage anatomical structure due to caused by the formation obstacle or dysplasia of heart and big blood vessel is abnormal, or answers after birth
The channel being automatically closed fails the situation of closure (belonging to normal in fetus).Congenital heart disease rate can not look down upon, and account for birth
The 0.4%~1% of baby living, it means that China increases patients with congenital heart 15~200,000 newly every year.
Currently with the rapid development of intervention equipment and equipment, heart intervention treating using more and more extensive, make room
It is more widely applied every centesis.Nineteen fifty-nine Ross etc. reports the animal experiment study of atrial septal puncture art, the same year
Atrial septal puncture art is applied to clinic for the first time by Cope and Rossdeng etc..The atrial septal puncture art at initial stage, leads using through right room
The method of pipe puncture needle Direct perforantes atrial septum, nineteen sixty Brockenbrough and Brawnwald etc. are to above-mentioned atrial septal puncture
Method is improved, and is firstly introduced guide wire technology, while puncture needle is improved to the tapered pyramidal structure in distal end, is increased
The safety of operation.Mullins in 1977 etc. is that transseptal catheterization is configured with epitheca, further improves atrial septal puncture
The operability and safety of art.
Effort is explored by many years of clinician, classical Ross method atrial septum wears the method and has obtained continuous improvement,
But since X ray image is flat image, the position in the direction and heart of puncture needle is not can accurately reflect and accurately judged
It sets, not can determine that whether be located at fossa ovalis when puncture.Intracardiac echocardiography (ICE) guides carry out atrial septal puncture in real time, can
Accurately to judge the anatomical position of fossa ovalis, it is particularly suitable for merging atrial septum aneurysm of membranous septum, spacer portion plumpness and atrial septum
The special patient of equal atrial septums anatomical structure after neoplasty.Although ICE can accurate measurements and guide atrial septal puncture needle end
Traffic direction effectively avoid and reduce the risk of operation to be accurately positioned atrial septal puncture point.
If atrial septal puncture point position is satisfied, puncture needle is gently pushed forward, fossa ovalis can be punctured and enter the left heart
Room.After puncture needle penetrates atrium sinistrum, short distance pushes puncture needle, and operation is soft, puncture needle dynamics is controlled, after avoiding puncture
Inertia strength, then fixed puncture is outer, then short distance pushing sheath tube, finally fixes sheath.Or point of puncture thicker to atrial septum is not
Flesh is spaced in film portion person or puncture needle and enters atrium sinistrum, but sheath should be avoided blindly pushed hard at this time by atrial septum difficulty
Send, sheath should be avoided advance by rear inertia firmly pushing, Overexertion can because of effect of inertia, lead to inserting needle too depth and
Wear out left atrial wall.Conduit enters atrium sinistrum through open oval foramen, if failing to identify in time, continues firmly to push, serious person
It can lead to impair cardiac rear wall.
Used puncture instrument is dedicated to solving the orientation problem of puncture position in the prior art, in puncture needle component
Positioning mechanism is set, the restriction of the spatial position selection and puncture needle needle point direction of travel of puncture target spot is capable of by locator,
But still not can solve prevents the problem of piercing through heart rear wall when puncturing, therefore, it is necessary to a kind of warps that can control puncture needle dynamics
Transportation system is intervened in atrial septum, and puncture needle will not be because of puncture when can guarantee to puncture, and can be avoided interventricular septum puncturing operation
Inertia strength impair cardiac rear wall afterwards is of great significance to prevention postoperative complication.
