Description

A kind of femoral artery shunts intrusion pipe
Technical field
The present invention relates to medical device correlative technology field, specially a kind of femoral artery shunting intrusion pipe.
Background technology
In cardiovascular injuries surgery in the prior art, peripheral arterial blood vessel (such as femoral artery) intubation is most common applied to 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 larger femoral artery infusion pipe insertion compared with Small femoral artery, particularly when above-mentioned two pipe caliber 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.Particularly It is more easy to occur in the situation for needing the femoral arteriography time to grow, a few hours or more than ten hours may be up in Great Vessel Operations, and In vitro membrane lung Advanced Life support when be more easy to occur up to a couple of days or several weeks, distal limb ischemic, or even completely necrosis and Amputation, and the serious threat to life of other undesirable elements that necrosis is brought.
Although there is the design for solving femoral artery distal ischemia in the prior art, but still it is not that preferable femoral artery distal end irrigates Isocon.Chinese patent discloses extracorporal circulatory system two-way filling arterial cannulation (201620728924.8), the artery of the invention The head distalmost end of intubation body be cecum, the both sides on head respectively perforate and reach the purpose that body follows two-way filling, intubation head The vertical implanted unit arterial lumen in portion, but femoral artery itself is comparatively fine, the less easily abjection blood vessel of insertion portion, is to protect in clinical Card arterial perfusion pipe is not easy under high pressure, often needs 5~10cm of implantation;In addition tube wall is more flexible, can not after intubation is fixed Intubation is set to be in ideal position, position can not reach the purpose of two-way filling after somewhat changing, or even influence body circulation perfusion, sternly Threat to life during weight.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 general structure of the arterial cannulation of the invention, and operation needs longitudinal incision to move Blood vessel wall, at least need oddi's sphincteroplasty 3cm or longer just to insert intubation, could fix and insert after being sewed up the incision again after incision Manage, free longer blood vessel is needed in art, increases wound and operating time;When needing to extract intubation, it is necessary to be again turned on cutting Mouthful, blood vessel near-end is blocked, sutures arteriotomy, operation wound is larger again, and operation is not convenient;Long range stringer otch artery, Long term may cause hemadostewnosis.
In clinic, doctor more using CVC insertion femoral artery distal end and rise do perfusion branch to far-end of limb confession Blood.The distal end side wall of CVC 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, cause 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 a kind of femoral artery shunting intrusion pipe.
