Description

Budd-Chiari syndrome interventional therapy simulation training device

technical field

The utility model relates to a simulated training device for interventional treatment of Budd-Chiari syndrome, which belongs to the technical field of medical simulation devices.

Background technique

Budd-Chiari syndrome (BCS) is caused by hepatic venous outflow tract obstruction and/or inferior vena cava obstructive lesions in the upper part of its opening caused by various reasons, often accompanied by symptoms of inferior vena cava hypertension Posthepatic portal hypertension. Budd-Chiari syndrome in my country is mainly of the inferior vena cava or hepatic vein septum obstruction type, and its pathological feature is that a septum in the inferior vena cava or hepatic vein completely or partially blocks the venous vessel, resulting in the inability or slow passage of blood flow. Interventional therapy has become the main treatment for Budd-Chiari syndrome due to its advantages of small trauma, simple operation, few complications and repeatable operation. At present, interventional therapy uses a steel needle to rupture the membrane and expand the balloon to tear the diaphragm and open the blood vessel to achieve the therapeutic effect. However, it is difficult for beginners to grasp the strength of steel needle rupture and balloon expansion, which brings improper treatment and surgical risks to patients. At present, there is an urgent need for a Budd-Chiari syndrome simulation that can effectively simulate the surgical process and improve beginners' surgical skills. training equipment.

In order to achieve the above object, the utility model proposes a simulated training device for Budd-Chiari syndrome interventional treatment, including artificial veins, half-section human-shaped fixing grooves, artificial veins installed in the half-section human-shaped fixing grooves, including inferior vena cava blood vessels , the left hepatic vein, the middle hepatic vein, the right hepatic vein, and the femoral veins on both sides. On the basis of the above structure, artificial diaphragms, fixed sheaths and liquid valves are also set up. Among them, four artificial diaphragms are set, respectively It is installed above the hepatic vein opening of the inferior vena cava in the artificial vein and at the proximal end of the left, middle and right hepatic veins, and the liquid valve is set at the distal end of the inferior vena cava in the artificial vein to control the blueness of the inferior vena cava. flow of colored liquid. There are two fixed sheaths, which are fixed at the distal ends of the femoral veins on both sides, and are used to insert catheters during simulated interventional treatments.

Further, the material of the artificial venous vessel is a transparent elastic soft rubber tube.

Further, the material of the half-section human-shaped fixing groove is rubber.

Further, the liquid valve is provided with a quick connector and a threaded bayonet.

The utility model simulates the blood vessel conditions of patients with Budd-Chiari syndrome by setting a half-section human-shaped fixing groove and artificial vein blood vessels, and adding artificial diaphragms to the artificial vein blood vessels; at the same time, adding a liquid valve and a fixed sheath, during simulation training, First open the liquid valve to let the blue liquid flow into the upper blood vessel, then insert the catheter into the fixed sheath and slowly advance in the blood vessel until it touches the artificial septum and stop, use a steel needle to explore the weak area of the artificial septum and pass through it, use a ball After repeated expansion of the artificial diaphragm, the stent is placed; the operation is simple, and the process of Budd-Chiari syndrome operation is effectively simulated, improving the surgical skills of beginners.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, a simulation training device for interventional treatment of Budd-Chiari syndrome includes an artificial venous vessel 1 and a half-section humanoid fixing groove 2, and the artificial venous blood vessel 1 is installed in the half-section humanoid fixing groove 2, including the lower chamber Venous blood vessels, left hepatic vein blood vessels, middle hepatic vein blood vessels, right hepatic vein blood vessels, femoral vein blood vessels on both sides, and artificial diaphragm 3, fixed sheath 4, liquid valve 5 and blue liquid 8, wherein artificial diaphragm 3 is set in four one, installed respectively above the opening of the hepatic vein of the inferior vena cava in the artificial vein 1 and at the proximal end of the left, middle and right hepatic veins, the liquid valve 5 is arranged at the distal end of the inferior vena cava in the artificial vein 1, and the liquid valve The artificial vein 1 below the 5 is provided with a blue liquid 8, and two fixed sheaths 4 are provided, which are fixed at the distal ends of the femoral veins on both sides.

In order to simulate the real human body and veins, the material of artificial veins 1 is made of transparent elastic soft rubber tube, and the material of half-section human-shaped fixing groove 2 is made of rubber.

For faster replacement and cleaning, the liquid valve 5 is provided with a quick connector 6 and a threaded bayonet 7, which facilitates quick replacement of the blood vessels above the liquid valve 5 .

During the simulation training, first open the liquid valve 5, so that the blue liquid 8 flows into the artificial vein 1; then insert the catheter into the fixed sheath 4 and slowly advance in the blood vessel until it touches the artificial septum 3, then probe the artificial septum with a steel needle 3 and pass through the weak area, the artificial diaphragm 3 is repeatedly expanded with a balloon, and the stent is inserted to perform membrane rupture and balloon expansion exercises of the inferior vena cava and hepatic vein respectively. After the artificial septum 3 is perforated, the operation of the membrane-like Budd-Chiari syndrome obstructed by a hole can be simulated, the position of the hole is probed with a catheter, the membrane is ruptured, the balloon is expanded, and the stent is placed. After the operation, the model is erected so that the blue liquid 8 accumulates below the liquid valve 5, the liquid valve 5 is closed, the blood vessels above it are replaced as a whole, and a new round of membrane rupture, balloon, and stent implantation and expansion is started. .

In summary, the utility model simulates the vascular situation of patients with Budd-Chiari syndrome by setting a half-section human-shaped fixing groove 2 and an artificial venous vessel 1, and adding an artificial diaphragm 3 to the artificial venous vessel 1; at the same time, a liquid valve is added 5 and the fixed sheath 4, during simulation training, first open the liquid valve 5, so that the blue liquid 8 flows into the upper artificial vein 1; then insert the catheter into the fixed sheath 4 and slowly advance in the blood vessel until it touches the artificial diaphragm 3 Stop, use a steel needle to probe the weak area of the artificial septum 3 and pass through it, use a balloon to repeatedly expand the artificial septum 3, and then insert a stent; the operation is simple and effectively simulates the process of Budd-Chiari syndrome surgery, improving Beginners' surgical skills, thereby avoiding the difficulty of beginners in grasping the strength of steel needle rupture and balloon expansion, which may bring improper treatment and surgical risks to patients.
