Description
Technical Field
the invention belongs to the technical field of medical devices, and particularly relates to a blood supply continuous device shunt catheter for anastomosing blood vessels during a heart surgery non-stop coronary artery bypass grafting operation, which is a blood supply type shunt catheter device.
Background
Coronary Artery Bypass Grafting (CABG) is an important approach in the field of cardiac surgery to treat coronary heart disease. In recent years, continuous coronary artery bypass grafting (opCABG) has been widely used in clinical practice due to the advanced age, critically ill patients, and the improvement of surgical techniques. In the implementation process of the operation, a shunt bolt is needed to be used for continuously providing blood flow for a diseased blood vessel of a patient for a target anastomotic blood vessel so as to ensure the blood supply of the far-end cardiac muscle and provide safety guarantee for the patient during the operation. The traditional shunt plug in clinic is a two-way blood supply type shunt plug. There are a number of disadvantages: the installation is inconvenient without a handheld fixed facility; severe avascular lesions fail to provide a continuous blood flow; the device has the defects of difficult installation of blood vessels with deep positions and the like.
Disclosure of Invention
The invention aims to overcome the defects in the prior art, and provides an aorta-coronary artery shunt catheter used in clinic aiming at the characteristics of serious vascular disease, more vascular diseases and difficult anastomosis position of patients with non-stop jumping coronary artery bypass transplantation in the prior clinic.
The purpose of the invention is realized by the following technical scheme:
The utility model provides an aorta-coronary artery reposition of redundant personnel pipe that uses in clinical, includes connecting pipe, tee bend reposition of redundant personnel bolt and aorta link, and the one end of connecting pipe links to each other with the aorta link, and the other end is connected with one of them expert of tee bend reposition of redundant personnel bolt, and the other two expert of tee bend reposition of redundant personnel bolt are used for implanting the coronary artery of pathological change, aorta link is used for connecting the aorta, is equipped with the biplane that is used for fixing on the connecting pipe of aorta link, still be equipped with blood flow control in proper order on the connecting pipe between biplane and the tee bend reposition of.
Further, the connecting pipe is a transparent rubber hose.
Further, the three-way switch is used for supplying blood through a syringe.
Compared with the prior art, the technical scheme of the invention has the following beneficial effects:
The shunt catheter can be connected with the aorta, has the effects of sustainable blood supply and convenient installation, can realize the continuous jump coronary artery bypass transplantation patients, ensures the safety of critical patients because the distal end vascular lesion continuously supplies blood when the vessels are anastomosed in the operation, and can be suitable for various continuous jump coronary artery bypass transplantation patients.

Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1, the invention protects an aorta-coronary artery shunt catheter used in clinic, which comprises a connecting pipe 4, a three-way shunt plug 1 and an aorta connecting end 2, wherein one end of the connecting pipe 4 is connected with the aorta connecting end 2, the other end of the connecting pipe 4 is connected with one passage of the three-way shunt plug 1, and the other two passages of the three-way shunt plug 1 are used for implanting diseased coronary arteries; a blood flow control clamp 5 and a three-way switch 6 are sequentially arranged on a connecting pipe 4 between the double wings 3 and the three-way shunt bolt 1.
After the aorta connecting end 2 is implanted into the aorta, the aorta end is strictly fixed through the double-wing 3 device fixed on two sides, and blood supply safety and no bleeding are guaranteed.
The connecting tube 4 is used for providing continuous blood flow between the aorta and the coronary artery, is composed of a transparent rubber hose, and can be flexibly moved in length, so that the operation of an operator is not influenced when the position is moved in an operation.
The blood flow control clamp 5 can adjust the blood flow of the blood supply of the aorta and clamp the blood flow, so that the operation of an operator can be conveniently carried out according to the requirement of the vascular lesion in the operation.
The three-way shunt bolt 1 can provide different models according to the weight and the thickness of the blood vessel of a patient, two ends of the three-way shunt bolt are inserted into the far end and the near end of the coronary vessel of the patient, and the middle three-way end and the aorta form a blood supply connecting pipeline.
Specifically, after the shunt catheter is installed, a blood supply bypass between the aorta and the coronary lesion blood vessel can be formed, continuous and adjustable uninterrupted blood supply can be provided no matter whether the lesion blood vessel has blood flow per se, and the blood can be supplied by using an injector at the position of the three-way switch 6. Because the three-way shunt bolt 1 is in a three-way form, the three-way end can be held by hand to exert force and fixed, so that the shunt catheter can be conveniently installed.
The utility model discloses reposition of redundant personnel pipe concrete implementation step is as follows:
1. carrying out purse-string suture on the aorta end by using a plulin wire, puncturing the aorta connecting end by using a sharp knife, inserting the sharp knife into the aorta, and fastening the purse-string wire, and fixing the two wings on the aorta by using a thin blocking tube to ensure firmness;
2. The blood flow control clamp 5 on the blood supply connecting pipe 4 is clamped to prevent the blood flow from overflowing and remove the gas at the shunt plug end of the tee joint;
3. The two-way branch at the end of the three-way shunt plug is implanted at the far end and the near end of the coronary vessel with pathological changes, and the blood flow control clamp 5 is adjusted according to the actual condition of a patient so as to adjust the proper flow. The installation and implementation of the shunt tubes is completed.
the present invention is not limited to the above-described embodiments. The foregoing description of the specific embodiments is intended to describe and illustrate the technical solutions of the present invention, and the above specific embodiments are merely illustrative and not restrictive. Those skilled in the art can make many changes and modifications to the invention without departing from the spirit and scope of the invention as defined in the appended claims.
