Description
Technical field
The present invention relates to a kind of the field of medical instrument technology, are capable of providing two-way filling more particularly, to one kind, effectively fill
Infuse the peripheral arterial Intubaction device for the two-way filling that blood flow cross-section product is big, resistance of blood flow is small, installation is simple and quick.
Background technique
Arterial perfusion pipe is inserted into aorta or peripheral arterial to carry out extracorporal circulatory system is most intracardiac repair under direct vision hands
Art and operation on aorta must operate.Currently, the arterial cannulation clinically used be all different diameter specifications plastic tube or
The plastic tube for thering is spring steel wire to reinforce in wall.For the aorta being relatively large in diameter, these arterial cannulations usually can meet body
Outer circulation is to traffic requirement.But with the rapid growth of cardiac minimally-invasive surgery and operation on aorta quantity, need to implement femoral artery,
The case where surroundings arterial cannulation such as axillary artery or innominate artery, is also more and more, and the diameter of these arteries is smaller, usually in 0.8-
1.2 centimetre.In this case, there is apparent shortcoming and defect for existing arterial cannulation product, specificallyUnidirectionally
Perfusion.Intubation is usually sent into the proximal part of catheter position, the telecentricity of catheter position by the intubation of peripheral arterial by peripheral blood vessel
End blood vessel is blocked until pulling out intubation at the end of operation.Since cardiovascular injuries operation is usually extremely complex, so far
Hold the Xining of blood vessel longer, it is few then more than one hour, more then 6-7 hours or even longer.Distal limb is due to Ischemia Time
It is long, the functional lesion of the anerobic glycolysises such as a large amount of lactic acid product or even thrombosis, remote organization and internal organs can be generated, to patient
Postoperative rehabilitation causes significantly to adversely affect.Effectively perfusion blood flow cross-section product is smaller.Due to current arterial cannulation tube wall compared with
Thick (usually at 1 millimeter or so), lumen is relatively small, and resistance of blood flow is caused to increase, and influences irrigation flow, aggravates Blood damage,
Especially when vessel lumen is smaller, such case is become apparent from.
Current peripheral arterial intubation product can not overcome above-mentioned drawback and then reach two-way filling, increase effectively perfusion blood
The purpose of flow section product, there is an urgent need to invent a kind of can reach to cause the new equipment of above-mentioned arterial perfusion effect to meet clinically day
The needs that benefit increases.
Summary of the invention
The present invention mainly solves peripheral arterial intubation in the prior art and is unable to reach two-way filling, increases effectively perfusion blood
The problem of flow section product provides the peripheral arterial Intubaction device of a kind of not occluding vascular, the two-way filling for reducing wound.
Above-mentioned technical problem of the invention is mainly to be addressed by following technical proposals: a kind of week of two-way filling
Arterial cannulation device, including outer tube are enclosed, the flexible inner tube being rotatably arranged in outer tube is provided with half on the front port of outer tube
Outer tube fixes edge, and the fixed edge of corresponding half inner tube is provided on the front port of inner tube, rotate inner tube after inner tube it is fixed along with
Outer tube is fixed along fixed edge in complete is pieced together, and casing is cased on outer tube, is provided on the front port of casing and interior fixation
Along the outer fixed edge that cooperation mutually compresses.Intubaction device is clipped on arterial wall by interior fixed edge and outer fixed edge in the present invention, is made
Must be intubated with the structure of arteriogenesis threeway, avoid because intubation be inserted into artery after to intra-arterial blood circulation caused by obstruction ask
Topic.Interior fixation is by the interior fixed edge of two halves and outer fixed along constituting in the present invention, when intubation is inserted into artery, by inner tube rotate to
Inner tube is fixed along the position for being stacked in the fixed edge of outer tube, interior fixed edge structure only unilateral at this time, convenient for outer tube is inserted into artery
Notch reduces the injury to human body but also can reduce the wound for cutting artery.After outer tube is inserted into artery, Forward is simultaneously
Rotating inner tube, rotate to inner tube it is fixed along and the fixed position along the state that do not overlap of outer tube, retract inner tube, inner tube it is fixed along with
The fixed edge of outer tube collectively forms fixed edge in complete.Interior fixed edge with Wall of Artery for being affixed in the present invention, outer fixation edge
For being affixed with artery outer wall.
