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 e...

Embodiment 1

[0041] Such as Figure 1-7 As shown, an inferior vena cava occlusion device for minimally invasive heart surgery includes a guide device 1, a functional catheter 2, a traction wire 3 and a blocking belt 4; the guide head 5 at the front end of the guide device 1 is provided with a side hole 501, A traction line 3 is fixed on the side hole 501 to reach the rear end from the inside of the guide device 1. The side of the guide device 1 with the side hole 501 is attached to the side with the functional catheter 2. The functional catheter 2 is provided with a blocking belt 4, and the blocking belt 4 Locking device 7 can be set on it;

[0042] The rear end of the guide device 1 is a hollow handle, and the front end of the hollow handle is successively provided with a hollow universal tube 102 and a conduit 101 at intervals, and a round guide head 5 is provided at the front end; The fixing column is set to connect with the ring sleeve 503 at the end of the pulling wire 3; the hollow ...

Embodiment 2

[0052] Such as Figure 8 , Figure 9 As shown, an operation method of an inferior vena cava occlusion device for minimally invasive heart surgery, pull the pulling wire handle 301 backward, so that the guide device 1 starts to bend from the front end, that is, the front end of the hollow handle of the guide device 1 is successively provided with hollow ten thousand To the pipe 102 and the catheter 101, the guide head 5 at the front end is provided with a side hole 501, and the side hole 501 is provided with a fixing post to be connected with the ring sleeve 503 at the end of the pulling wire 3; when pulling the pulling wire handle 301, the pulling wire 3 Pull the universal tube 102 at the front end of the guide device 1 to bend from one direction, so that the head end of the guide device 1 bends. At this time, the pull wire 3 can be locked by pressing the pull wire fixing button 6 to facilitate the operation of the guide device 1. Under the action of 4, the guide device 1 wil...

Embodiment 3

[0054] During minimally invasive heart surgery, an incision of about 4 cm is cut from the fourth rib position on the right side, and the surgical field of view is obtained through an endoscope; One end of the guide head 5 of the guide device 1 of the disconnecting device is inserted from the incision position, and with the assistance of the free pliers, the guide device 1 is bent from the front end by pulling the pulling wire handle 301 backward (such as Figure 8 ), that is, the front end of the hollow handle of the guide device 1 is provided with a hollow universal tube 102 and a conduit 101 at intervals in turn, and the guide head 5 at the front end is provided with a side hole 501, and the side hole 501 is provided with a fixed column and a ring at the end of the traction line 3 sleeve 503 connection; when pulling the pull wire handle 301, the universal tube 102 at the front end of the guide device 1 will bend from one direction when the pull wire 3 is pulled, so that the b...

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 ...
