Description
Technical field
The invention belongs to medical appliance field, relate generally to a kind of have the function of artery anti-return for department of cardiovascular surgery
Brain infusion cannula.
Background technique
Row aorta bow portion is needed to replace in Aortic arch aneurysm or Stanford A type dissection of aorta operative treatment.In master
It is required to stop systemic blood circulation at low temperature in arch of aorta portion displacement technique.Stop needing to protect brain tissue in cyclic process
Shield, it includes unilateral selective cerebral perfusion, bilateral selective cerebral perfusion etc. that now clinically hypothermia circulatory arrest brain, which protects common measure,.It is single
Side selective cerebral perfusion is mostly to be irrigated through axillary artery or innominate artery intubation, is now widely used by the country, if but intracerebral
Willis ring dysplasia can lead to opposite side cerebral hyoperfusion and cause serious cerebral complication；Bilateral selective cerebral perfusion is the right side
Axillary artery intubation, left common carotid intubation or bilateral common carotid arteries are intubated row bilateral selective cerebral perfusion, and brain protecting effect is true
It cuts, existing domestic application is less.Row bilateral selective cerebral perfusion method is needed using brain infusion cannula, and prior art is usually to answer
With a conduit, one end is inserted into left common carotid, and the other end connects cardiopulmonary bypass unit row arterial perfusion.Since the country there is no
Dedicated brain infusion cannula, thus it is a kind of easy to operate, and perfusion is reliable, as far as possible reduction cerebral ischemic time, reduces cerebral pathology
Generation and improve the arch of aorta operation success rate medical instrument and method, become this field urgent problem.
Summary of the invention
It is a kind of for stopping recycling the protection of cardiovascular surgery process midbrain it is an object of the invention in view of the above deficiencies, provide
The applied brain infusion cannula with artery anti-return function there is no dedicated selective cerebral perfusion to be intubated to solve the existing country
Problem improves brain protecting effect and stops recycling the success rate of arch of aorta operation.
In order to solve the above technical problems, the invention adopts the following technical scheme:
A kind of brain infusion cannula with artery anti-return function for department of cardiovascular surgery, including brain infusion cannula sheet
Body, which is characterized in that further include blood-backflow preventing sacculus, the blood-backflow preventing sacculus is mounted on the brain infusion cannula ontology
Arterial end, and the sacculus that communicates with blood-backflow preventing sacculus shrinks side pipe and controls the sacculus and shrink the ball that side pipe is opened and closed
Capsule side pipe lockup switch.
Preferably, the arterial end of the brain infusion cannula ontology is in round and smooth taper or hemispherical.
Preferably, at least one is equipped between the arterial end of the brain infusion cannula ontology and the blood-backflow preventing sacculus
A blood transfusion side opening.
The beneficial effects of the present invention are:
One kind is provided to stop recycling applied by the protection of surgical procedure midbrain with artery anti-return for department of cardiovascular surgery
The brain infusion cannula of function can easily be filled brain by being in round and smooth taper in brain infusion cannula ontology one end (arterial end)
In note intubation merging arteria carotis communis, after the completion of merging, the sacculus side pipe lockup switch of sacculus side pipe one end is opened, into sacculus
Saline injection is allowed to expand interruption artery, and brain blood is prevented to flow back, and guarantees brain irrigation flow, closes sacculus side pipe locking
Switch.The connection ontology other end and cardiopulmonary bypass unit can pass through arteria carotis communis row selective cerebral perfusion.Right axillary artery can be passed through
Intubation+left common carotid selective cerebral perfusion intubation or bilateral common carotid arteries selective cerebral perfusion are intubated row bilateral selective brain
Perfusion, it is definite to carry out brain protection.And during perfusion, multiple side openings of brain infusion cannula ontology one end can avoid intubation
With arterial wall it is adherent caused by hemoperfusion obstacle.
It is provided by the present invention it is this stop recycling applied by the protection of surgical procedure midbrain for department of cardiovascular surgery have it is dynamic
The brain infusion cannula of arteries and veins anti-return function is simple and practical, easy to operate, and brain perfusion is definite, and protecting effect is good, while structure is simple,
It is easy to spread suitable for production.
