Description

Artificial blood vessel anastomosis trainer and method of use thereof

technical field

The invention relates to an artificial blood vessel anastomosis trainer and a using method thereof, belonging to the technical field of artificial blood vessel suturing.

Background technique

At present, the effective treatment methods for dissecting aneurysm, thoracoabdominal aortic aneurysm, and extremity large vessel aneurysm are mainly surgical artificial vascular replacement. However, the current problem is that the operation is risky and requires high technical requirements for surgeons. From the perspective of surgery, how to perform vascular anastomosis safely and quickly is the key to improving the success rate of surgery, reducing surgical mortality and reducing surgical complications. Key factor. Especially in the surgical treatment of severe macrovascular diseases (such as complex and extensive dissecting aneurysms), whether the vascular anastomosis can be completed quickly and safely is a prerequisite for successful surgery.

The method of present blood vessel anastomosis mainly is to carry out suture anastomosis with suture. This is a safe and effective method, but it has high technical requirements for surgeons, and it takes a lot of operating time, and sometimes it is necessary to repair the bleeding. The current training for on-the-job doctors is to let them observe the doctor's operation, Accumulate experience by yourself, and do not have relevant practice equipment and materials, so the existing method for practicing suturing blood vessels is still not perfect.

Contents of the invention

The object of the present invention is to provide a kind of artificial blood vessel anastomosis training device which is simple in structure, practical and easy to operate, which is convenient for medical staff to practice blood vessel suturing, and can timely display problems and defects during suturing, and improve the practice efficiency of medical staff. The method of use thereof overcomes the deficiencies of the prior art.

The present invention is constituted as follows: the use method of the artificial blood vessel anastomosis training device, firstly, a fixed bracket is made on the worktable, and two artificial blood vessels are placed on the fixed bracket, and the two artificial blood vessels are scalable artificial blood vessels and conventional artificial blood vessels. One end of the stretchable artificial blood vessel is connected with a three-phase joint, and the other two ends of the three-phase joint are connected with a pressure measuring tube and a liquid injection tube. The other end of the stretchable artificial blood vessel is opposite to the one end of the conventional blood vessel. Practice During operation, medical personnel adjust the stretchable artificial blood vessel according to the position of the blood vessel, suture the stretchable artificial blood vessel with the conventional artificial blood vessel, and then inject colored dye into the injection tube. When the colored dye flows through the stretchable artificial blood vessel and When conventional artificial blood vessel joints are used, it is possible to observe whether there is leakage and whether there are suture defects.

The artificial blood vessel anastomosis trainer includes a worktable, on which a fixed bracket is arranged, and two sections of artificial blood vessels are arranged on the fixed bracket, the artificial blood vessels are scalable artificial blood vessels and conventional artificial blood vessels, and the adjustable One end of the stretchable artificial blood vessel is provided with a three-phase joint, and the other two ends of the three-phase joint are connected with a pressure measuring tube and a liquid injection tube. The other end of the stretchable artificial blood vessel corresponds to the mouth of a conventional artificial blood vessel.

The stretchable artificial blood vessel is provided with adjustment seams.

A colored dye is arranged in the liquid injection tube.

Compared with the prior art, the present invention not only has the advantages of simple structure and ingenious design, but also can help a group of medical staff to practice blood vessel suturing, find out the defects and deficiencies in suturing in time, and improve the practice efficiency of medical staff, etc. The blood vessels can be used repeatedly, and the leakage can be observed when the pressure is high by measuring the pressure, because the blood pressure of large blood vessels sometimes fluctuates greatly.

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

Implementation of the present invention: the use method of the artificial blood vessel anastomosis training device, firstly make a fixed bracket on the worktable, place two artificial blood vessels on the fixed bracket, and the two artificial blood vessels are scalable artificial blood vessels and conventional artificial blood vessels. One end of the stretchable artificial blood vessel is connected with a three-phase joint, and the other two ends of the three-phase joint are connected with a pressure measuring tube and a liquid injection tube. The other end of the stretchable artificial blood vessel is opposite to the one end of the conventional blood vessel. Practice During operation, medical personnel adjust the stretchable artificial blood vessel according to the position of the blood vessel, suture the stretchable artificial blood vessel with the conventional artificial blood vessel, and then inject colored dye into the injection tube. When the colored dye flows through the stretchable artificial blood vessel and When conventional artificial blood vessel joints are used, it is possible to observe whether there is leakage and whether there are suture defects.

The artificial blood vessel anastomosis trainer includes a worktable 1, a fixed support 2 is arranged on the worktable 1, two artificial blood vessels are arranged on the fixed support 2, and the artificial blood vessels are scalable artificial blood vessels 3 and conventional artificial blood vessels. Blood vessel 4, one end of the telescopic artificial blood vessel 3 is provided with a three-phase connector 5, and the other two ends of the three-phase connector 5 are connected with a pressure measuring tube 6 and a liquid injection tube 7, and the nozzle of the other end of the telescopic artificial blood vessel 3 is connected to the The nozzle of conventional artificial blood vessel 4 is corresponding.

The stretchable artificial blood vessel 3 is provided with an adjustment slit 8 .

A colored dye is arranged in the liquid injection tube 7 .

The present invention mainly places two sections of artificial blood vessels on the fixed bracket 2 on the worktable 1 for positioning, and then when suturing, the medical personnel adjust the stretchable artificial blood vessels 3 according to the distance, and utilize the adjustment provided on the stretchable artificial blood vessels 3 Seam 8, stretch the stretchable artificial blood vessel 3, lap one end of the stretchable artificial blood vessel 3 on the nozzle of the conventional artificial blood vessel 4 and sew it up. After the stitching is finished, squeeze the injection tube 7 firmly When the dye of the color in the injection tube 7 flows through the conventional artificial blood vessel 4 and the stretchable artificial blood vessel 3, it can be observed whether there is dye leakage and suture defects, and the pressure test tube 6 can also be used for pressure testing. While the group of medical staff is practicing blood vessel suturing, the defects and deficiencies in suturing can be found in time to improve the practice efficiency of medical staff.

The invention is convenient to replace, can be used repeatedly, and has simple structure.
