Inferior vena caval blocking device for minimally invasive cardiac surgery

Abstract

The invention belongs to the technical field of ligation or pressing for the in-vivo tubular part, and discloses an inferior vena caval blocking device for minimally invasive cardiac surgery. For thedevice, a side hole is arranged in a guide head at the front end of a guide device, a traction line is fixed on the side hole and reaches the rear end from the inside of the guide device, a function catheter attaches to one side, with the side hole, of the outer wall of the guide device, a blocking belt is arranged in the function catheter, and a locking device is arranged on the blocking belt; ahollow handle is arranged at the rear end of the guide device, and traction line fixing buttons are arranged on the hollow handle; the function catheter attaches to one side, with the side hole, of the outer wall of the guide device; and the hollow handle is provided with the two traction line fixing buttons, and the two traction line fixing buttons are axially symmetric on the hollow handle. Forthe inferior vena caval blocking device for minimally invasive cardiac surgery, in the limited operation space, the inferior vena cava is efficiently and rapidly separated, the blocking belt sleeves for realizing blocking, and then the belt head end of the blocking belt passes through the locking device for realizing locking. The surgery efficiency is effectively improved, the complication and surgery time are reduced, in addition, the device has the advantages that the structural design is reasonable, the use is convenient and safe, and thus the device is suitable for being popularized for use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an inferior vena cava blocking device for minimally invasive heart surgery. Background technique [0002] Heart disease is the number one killer of human health. About one-third of the number of people who die of diseases in the world every year is caused by heart disease. The incidence rate has been showing a clear upward trend. There are about 3.5 million people in my country People die of heart disease. In the past ten years, minimally invasive cardiac surgery has been widely used in the world. Although there is still no clear definition and standard for minimally invasive cardiac surgery, there is a consensus that, on the premise of ensuring the safety of patients, reducing the surgical incision or avoiding extracorporeal circulation can reduce or alleviate the physical and mental impact of surgery on patients. Aspects of trauma. On the other hand, the narrowing of ...

AI Technical Summary

Problems solved by technology

[0005] (1) In a narrow space, it is very difficult to separate the inferior vena cava, which greatly prolongs the operation time and increases the difficulty of operation. Due to the small incision and the deep position of the inferior vena cava, it is very difficult to separate the inferior vena cava cuff , the existing operation method generally needs to use forceps to separate it little by little, because the incision is far away from the inferior vena cava, it is difficult to separate it quickly even with forceps

[0006] (2) After the inferior vena cava is separated from the tissue, when the cuff is blocked, it is difficult to bend the soft blocking tape in a small space to block the blocking tape on the inferior vena cava. Difficult to operate

As a result, the occlusion of the inferior vena cava takes too much time. At the same time, the operation cannot be performed if the inferior vena cava cannot be effectively blocked. The patient's long-term coma may lead to life-threatening and medical accidents.
