Description
Technical field
The utility model relates to medical device correlative technology field, specially a kind of femoral artery shunts intrusion pipe.
Background technique
Cardiovascular injuries surgery in the prior art, peripheral arterial blood vessel (such as femoral artery) intubation be it is most common be applied to it is micro-
Create the surgical technic that openheart surgery, Great Vessel Operations and Advanced Life support for example external membrane lung (ECMO) of system.Femoral artery is inserted
For pipe in order to ensure the total body perfusion flow of enough satisfaction, the caliber of intubation is often larger, when the insertion of biggish femoral artery infusion pipe compared with
Small femoral artery, especially when the caliber of above-mentioned two pipe quite or femoral artery occur spasm when, artery insertion intrusion pipe it is normal
The blood supply of far-end of limb is hindered, even completely blocking blood flow causes far-end of limb ischemic to increase perioperative complications.Especially
It is easier to occur in the situation for needing the femoral arteriography time long, a few hours or more than ten hours may be up in Great Vessel Operations, and
In vitro membrane lung Advanced Life support when up to a couple of days or several weeks, distal limb ischemic is easier to occur, in addition completely necrosis and
Amputation, and the serious threat to life of downright bad other undesirable elements of bring.
It although there is the design for solving femoral artery distal ischemia in the prior art, but still is not that ideal femoral artery distal end is perfused
Isocon.Chinese patent discloses extracorporal circulatory system two-way filling arterial cannulation (201620728924.8), the utility model
The head distalmost end of arterial cannulation tube body be cecum, the two sides on head respectively aperture and achieve the purpose that body follows two-way filling, insert
The vertical implanted unit arterial lumen of tube head, but femoral artery itself is comparatively fine, the less easy abjection blood vessel of insertion portion, in clinic
To guarantee that arterial perfusion pipe is not easy under high pressure, often need to be implanted into 5~10cm；In addition tube wall is more flexible, after intubation is fixed
Intubation cannot be made in ideal position, position cannot achieve the purpose that two-way filling after slightly changing, or even influence body circulation and fill
Note, threat to life when serious.Another patent, without the axillary artery intubation of perfusion ischemic area and application during extracorporal circulatory system
(201410522552.9), " T " or Y-shaped is presented in the overall structure of the arterial cannulation of the utility model, and operation needs stringer to cut
Blood vessel wall is started, at least needs oddi's sphincteroplasty 3cm or longer that could be placed in intubation, could be consolidated after sewing up the incision again after incision
Fixed to be intubated, need to dissociate longer blood vessel in art, increases wound and operating time；When needing to extract intubation, need to beat again
Notch blocks blood vessel proximal end, sutures arteriotomy, operation wound is larger again, inconvenient benefit；Long range stringer notch is dynamic
Arteries and veins, long term may cause hemadostewnosis.
In clinic, doctor mostly use central venous catheter insertion femoral artery distal end and rise do perfusion branch to far-end of limb confession
Blood.The distal end side wall of central venous catheter has multiple tiny side openings, tiny at a high speed when full flow or high flow perfusion
Blood flow beam directly impact arterial blood tube wall, lead to hematoclasis and vascular endothelial cell damage, Arterial thrombosis causes limb
The severe complications such as body distal embolization, and arteriarctia at a specified future date, therefore propose that a kind of femoral artery shunts intrusion pipe.
