Abstract
A double-balloon intravascular catheter is characterized in that one end of a catheter body is open, the other end of the catheter body is provided with a fixed sleeve, a first balloon and a second balloon which are separated by a certain distance are coated and fixed on the outer wall of the catheter body close to the open end of the catheter body, a balloon connecting pipe is inserted into an inner cavity of the catheter body through the fixed sleeve and is communicated with inner cavities of the two balloons, a bleeding hole is formed in the catheter body and is positioned between the second balloon and the fixed sleeve and close to the second balloon, and a blood transfusion tube is arranged in the bleeding hole and is inserted into the inner cavity of the catheter body from the open end of. The inner catheter can block arterial blood from flowing through an operation part during operation, and meanwhile, the arterial blood can flow out of an artery at the downstream of the operation part through a bleeding hole through an inner channel of the catheter body and be perfused into the artery, so that the normal flow of the blood flow is not blocked during the operation, and the inner catheter has important effects on reducing the incidence rate of important visceral organ complications and improving the survival rate and the survival quality of postoperative patients.
Description
Technical field
The invention belongs to medical apparatus and instruments, the catheter in blood vessel of the dribbling capsule that particularly a kind of vascular operation is used.
Background technology
Aortic aneurysm, aortic stenosis are frequently-occurring disease, the commonly encountered diseases of vascular surgery, and aneurysm or narrow positions excision back artificial blood vessel orthotopic transplantation or direct coincideing are main treatment meanss.Carrying out for the ease of operation, need temporary blocking-up aorta in the operation, the medical apparatus and instruments that uses at present is sacculus catheter for arterial blood vessel, its structure is by the catheter tube opening one or two sacculus to be set, insert appendix, blood transfusion tube (also claiming tube chamber) from the other end of catheter tube, they are connected with the opening of each balloon lumen and catheter tube respectively, by filling sacculus interruption artery blood flow by phased manner.Chinese patent ZL 02113689.0 disclosed sacculus catheter for arterial blood vessel has only increased side opening of opening on the catheter tube and the carrier pipe that communicates with it (also claiming tube chamber) on the basis of said structure; so that be increased in blocking-up position far-end or/and near-end perfusion anticoagulant liquid; at the dirty position of important device perfusion protection liquid, measuring blood pressure, blood-sample withdrawal, local cooling, blood pressure lowering, to functions such as specific drugs.The problem that existing various sacculus catheter for arterial blood vessel exist is that the downstream at blocking-up position fully can not blood supply, thereby cause the blocking-up downstream the organ ischemia, if the ischemia of organ surpasses safe time limit, promptly may cause acute renal failure, spinal cord necrosis (paraplegia) and multiple organ dysfunction, therefore present operative mortality still higher (2%～6.8%).Surgeon is because the scruple aorta clamping time can not be finished aorta calmly and be rebuild, and open too early aorta causes amount of bleeding obviously to increase.High-order aortal blocking-up has simultaneously increased cardiac afterload, and upper part of the body blood pressure is increased, and also can cause the depletion of cardiac function, has increased the danger of anesthesia and operation greatly.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of can interruption artery blood flow underwent operative position, can in operation process, make two saccule catheter in blood vessel of the normal blood supply in downstream of operative site again.
Technical scheme of the present invention: existing two sacculus sacculus catheter for arterial blood vessel are improved, blood outlet hole is set on catheter tube, this blood outlet hole is positioned at from the outside of catheter tube opening sacculus far away, and the blood transfusion tube that communicates with blood outlet hole inserts the catheter tube inner chamber from the catheter tube opening.
Body one end opening of of the present invention pair of saccule catheter in blood vessel, the other end is equipped with fixed cover, at tube body opening, coat and be fixed with phase first sacculus across a certain distance on the outer wall of body, second sacculus, the sacculus connection tube that conducting or blocking-up gas (liquid) enter sacculus communicates by fixed cover insertion tube intracoelomic cavity and with the inner chamber of two sacculus, so that the full or contraction of control sacculus, body is provided with blood outlet hole, this blood outlet hole is between second sacculus and fixed cover and near second sacculus, blood outlet hole is equipped with blood transfusion tube, this blood transfusion tube is communicated with from body opening insertion tube intracoelomic cavity and with blood outlet hole, form the conduit internal channel, during operation, arterial blood enters blood transfusion tube from the arterial blood inlet of blood transfusion tube end, flows out perfusion operative site downstream through blood outlet hole.
Need when in operation process, artificial blood vessel being installed for the convenience of operating, can make the naked section that sacculus connection tube and blood transfusion tube are arranged between first sacculus and second sacculus from the disconnected and two saccule catheter in blood vessel of connection.
In order to make two saccule catheter in blood vessel have perfusion protection liquid, measuring blood pressure, blood-sample withdrawal; local cooling, blood pressure lowering, to functions such as specific drugs; at least be provided with a side opening that is useful on injectable drug or measures blood pressure on the body, this side opening communicates with side opening connection tube from fixed cover insertion tube intracoelomic cavity.
For improving biocompatibility, catheter tube can use heparin paint-on technique or other biotechnology.Be convenient location, the material of catheter tube can add the baric material.
Catheter tube, fixed cover, sacculus, sacculus connection tube, blood transfusion tube, side opening connection tube are made by medical macromolecular materials.
The present invention has following beneficial effect:
When 1, performing the operation, energy interruption artery blood flow underwent operative position, arterial blood can flow out the tremulous pulse in perfusion operative site downstream by conduit internal channel (blood transfusion tube) through blood outlet hole simultaneously, make in the operation the not proper flow of occlude blood, thereby to reducing the incidence rate of important organ complication, the survival rate and the life quality that improve postoperative patient have important function.
2, can alleviate the surgeon mental pressure of scruple aorta clamping time, guarantee to perform the operation and finish smoothly, improve the success rate of operation.
3, there is side opening to communicate on the catheter tube, can be used for treatment of diseases such as tumor with the external world.Conduit is inserted intra-arterial, and the blood vessel of supply tumor is in the middle of two sacculus, and after the inflated, the medicine that will treat tumor by the side opening connection tube injects the intermediary side opening of two sacculus, can reach the purpose of treatment.The method is simple to operate, and operation wound alleviates the injury of lonizing radiation to doctor, trouble both sides simultaneously much smaller than the interventional therapy of present tumor.
