Abstract
The utility model relates to an interbedded surgery surgical treatment of of aorta adopts and establishs the extracorporal circulatory system through the arteria femoralis intubate, and the selectivity brain fills under the profound hypothermia stops circulating, is the successful assurance of aorta intermediate layer operation. The utility model discloses a, special intubate of angularity arteria femoralis, include: intubate anterior segment, middle section and back end triplex, long 200mm, internal diameter 7mm, wall thickness 1mm, the intubate head becomes the inclined plane at 60 degrees angles, head 50mm before the intubate, well head 50mm, back head 100mm. Apart from head 50mm department, the intubate anterior segment becomes 135 degrees angles with the middle section, and the intubate middle section becomes 135 degrees angles with the back end. Make things convenient for art person to accomplish the arteria femoralis intubate in relative darker and narrow and small space, reduce blood vessel and tissue lesion on every side, avoid the deformation of arteria femoralis intubate, ensure the safety of performing the operation.
Description
Art
The extracorporeal circulation that this utility model relates in trunk surgical operation is set up.Along with the raising of China's economic development and living standards of the people, the sickness rate of atherosclerosis and hypertension constantly rises, and its dangerous complication dissection of aorta has also become commonly encountered diseases and frequently-occurring disease.And surgical operation is dissection of aorta essential therapeutic arsenals, the modus operandi of dissection of aorta is different from cardiac operation in general sense, and its method setting up extracorporeal circulation is more complicated, is the key factor ensureing successful surgery.
Technical background
Dissection of aorta operation relates to artificial blood vessel's replacement of aortic root, ascending aorta, aortic arch, and descending aorta stented vessel implantation, relates to heart, brain and cord dorsal potentials.Often need set up extracorporeal circulation through femoral arteriography, involve the cardiovascular disease of aortic arch at the descending operative treatment of Deep Hypothermia Circulatory Arrest.
Current femoral arteriography method is: above pubic tubercle and anterior superior iliac spine line mid point, longitudinally cuts skin, subcutaneous tissue, exposes stock artery and vein and also overlaps cotton rope.Block femoral artery far-end and proximal part successively after heparinization, middle catch cropping transverse incision, select No. 7 common tremulous pulse straight cutting pipes, insert femoral artery and unclamp proximal part blocking-up pincers, in intubate intravasation, length is about 5cm, and upward, proximal part cotton rope is tied a knot and fixed on mouth of pipe inclined-plane.
Because femoral artery position is very dark, appear difficulty, for obesity patient all the more so.If adopt common arterial cannulation, because this type of intubate itself is straight, in relative narrow space, operation has many difficulties, for general just like operation in deep-well abecedarian, easily cause difficult intubation, tunica intima may be caused to peel off or rupture of blood vessel, cause hemorrhage, arterial injury, limb ischemia etc.; Even if intubate success, also because femoral artery position is dark, arterial cannulation distortion, discounting may be caused, pump pressure is raised, affect extracorporeal circulation flow, cause the hypoperfusion of patient's multi viscera, cause serious consequence.
Summary of the invention
We find, cause that femoral arteriography difficulty and arterial cannulation give a discount, the reason of distortion is that this regional anatomic position is dark, and intubate used is again straight, very easily causes the not genial intubate discounting of intubate, distortion.And dissection of aorta patient mostly is fat and hyperpietic, body weight is large, and anatomical position is darker than common patient.In order to improve extracorporeal circulation effectiveness and the safety of trunk surgery, particularly for abecedarian, can guarantee that operation safety is with smooth, more stably, to set up easily and fixing femoral arteriography, safeguard blood haemodynamic stabilization, we are according to human anatomy and long-term clinical practice, invent the special intubate of angled femoral artery, by traditional tremulous pulse straight cutting pipe, change syllogic into, according to our clinical experience, angled between three sections of intubate, it can be made more to adapt to the feature that anatomical layer is dark and working place is narrow and small.
This utility model patent solves the technical scheme that its technical problem adopts: adopt medical organic material, manufacture the special intubate of angle femoral artery.This utility model comprises: intubate leading portion, stage casing and back segment three part.This utility model patent characteristic is: the special intubate of angled femoral artery, long 200mm, internal diameter 7mm, thickness of pipe wall 1mm; Intubate head becomes the inclined-plane at 60 degree of angles; Segment length 50mm before intubate; Middle segment length 50mm, rear segment length 100mm.Distance head 50mm place, intubate leading portion becomes 135 degree of angles with stage casing, intubate stage casing becomes 135 degree of angles with back segment.During use, block femoral artery far-end and proximal part successively after heparinization, middle catch cropping one transverse incision, select No. 7 special intubate of angled femoral artery, utilize the angle of formation of its leading portion, stage casing and back segment, in relatively dark and narrow space, insertion femoral artery, degree of depth 5cm in intubate intravasation, make mouth of pipe inclined-plane upward, proximal part cotton rope is tied a knot and is fixed, and right atrium just can be made a connection after inserting venous drainage pipe cooling, starts dissection of aorta operation.After operation terminates, pull out the special intubate of angled femoral artery, be interrupted or sew up femoral artery otch continuously.
The beneficial effect of this utility model patent is: facilitating patient relatively deeply and in narrow space completing femoral arteriography, reducing blood vessel and damaging surrounding tissue, guaranteeing operation safety; Avoid, because femoral artery position deeply and easily causes arterial cannulation distortion, discounting, pump pressure being raised, affecting extracorporeal circulation flow, cause patient's hypoperfusion, set up more stably, easily and fixing femoral arteriography, safeguard blood haemodynamic stabilization.
