Embodiment

[0027] Please refer to the accompanying drawings in the description; a transthoracic minimally invasive cardiac ventricular septal defect occluder delivery device, including a puncture needle 4, a guide wire 3, a delivery sheath 1 and a loading sheath 2. Both the delivery sheath and the loading sheath are made of flexible materials such as plastic.

[0028] The end of the delivery sheath 1 leads to the heart septal defect under the guidance of the guide wire 3. The cardiac occluder is installed in the loading sheath 2. After the loading sheath is docked with the delivery sheath, the cardiac occluder enters through the delivery sheath. The location and function of the cardiac septal defect.

[0029] Delivery sheath tube 1 is a sheath tube about 20 centimeters in length, and its end is provided with quick connector 11, and what matches with delivery sheath tube is expansion sheath tube 12, and this expansion sheath tube 12 just can be inserted in delivery sheath tube, and stretc...

Abstract

The invention discloses a transthoracic minimally invasive occlusion interventricular septum defection plugger conveying appliance. The invention is characterized in that the device comprises a locating line, a conveying passage and a cardiac plugger adaptor; one end of the conveying passage is lead to the invasive occlusion part of the interventricular septum guided by the locating line, the cardiac plugger is installed inside the plugger adaptor, after being butted with the conveying passage, the cardiac plugger adaptor enters the position of the interventricular septum defection through the conveying passage and begins to work at the position. The conveying is mainly characterized in that the entire device is short and small, and can be held by hands directly. The defection part can be closed as near as possible, and puncture, direction adjusting, guide rail building, and plugger releasing can be finished by only one person, during the operation, once the septum defection is not suitable for the method or the plugging fails, the incision can be directly extended upward and changed into the traditional thoracotomy, no extra incision is needed, or transferred from the cardiac catheter room to the operating room, and the security of the patient is greatly ensured.

Description

technical field [0001] The invention discloses a delivery device and a delivery method for delivering a heart occluder microtrauma to a specific defect position of the heart. Background technique [0002] Cardiac septal defect is a common disease. At present, there are three main methods to treat this disease in modern medicine. The specific methods and steps are as follows: [0003] 1. The most common method is to use thoracotomy. The specific situation is to cut the patient's front chest completely, establish extracorporeal circulation, stop the heart first, and then use surgery to suture the cardiac septal defect when the heart is still. patch repair. After the completion of the operation, drugs are used to restore the beating of the heart, after a series of special treatments, and finally sutured until the operation is completed. The advantage of this kind of operation is that it has a wide range of indications, and it can be effective for both atrial defect and ventri...
