Description
Technical field
It is the present invention relates to a kind of quality examination of medical 3D printing guide plate and processing support unit, in particular to a kind of
Guide plate fixing support rack.
Background technique
Aortic disease mainly includes aortic aneurysm (Aortic Aneurysm, AA) and dissection of aorta (Aortic
Dissection, AD), it is a kind of disease of common serious threat to life.If being not treated in time, once occur aneurysm or
Dissecting aneurysm rupture, case fatality rate are up to 78%-94%.In last century later half page, conventional therapy is the various actives for the treatment of
The standard method of arteries and veins disease, but with the surgical operation of dissection of aorta (Aortic Dissection, AD) for, operation
Case fatality rate is up to 21%~50%, and paraplegia rate is then up to 10%~36%.For abdominal aneurvsm (Abdominal Aortic
Aneurysm, AAA) open surgery effect it is preferable, but that there are still operation wounds is big, complication is more, post-operative recovery is slow, especially
The disadvantages of old Organ replication mortality is high.
With the rapid development of vascular operation technology and novel vascular intervention material in recent years, the Endovascular of low-risk
Treatment technology has become the developing direction of arotic disease treatment.Parodi in 1991 is complete using Endovascular artificial blood vessel guide plate
At the first abdominal aneurvsm intracavity operation (EVAR), overlay film guide plate is used for controlling for Human Thoracic Aortic Dissection again by Dake within 1994
It treats (TEVAR), Endovascular is received significant attention and generallyd use rapidly.
With the announcement of randomized controlled trial result of the aorta intracavitary therapy compared with conventional therapy, intracavitary therapy
Wound it is small, restore the features such as fast, postoperative complications and case fatality rate are low and be widely recognized and applied.
Using blood vessel guide plate carry out intracavitary therapy when, need in advance to guide plate carry out aperture, with formed with target blood and
The identical guide plate bracket of branch vessel, but the tapping equipment type that can be realized blood vessel guide plate venting techniques at present is rare, doctor
Can only manual aperture by rule of thumb, there is a problem of that position of opening is inaccurate.And lacks a kind of medical 3D printing guide plate and carrying out matter
When amount is checked and is further processed the problem of required fixed device.
Summary of the invention
