Blood occlusion device with function of preventing blood vessel cementation

Abstract

The invention discloses a blood occlusion device with a function of preventing blood vessel cementation. The blood occlusion device comprises a center pipe and an attached pipe, wherein a conical topgroove is formed in the right end inside the center pipe, a spring is fixed at the left end of the center pipe, and a draw-insert cylinder is movably inserted in the left end of the center pipe; a blood passing hole is formed in the side face of the draw-insert cylinder; a top block is fixed at the left end of the draw-insert cylinder; the other end of the spring is fixed on the right side of topblock; the left end of the draw-insert cylinder runs through the spring, and the right end of the draw-insert cylinder runs through the conical top block; the conical top block is positioned on the right side of the conical top groove, and the center pipe is supported through the conical top block, so that a blood vessel can be fixed after being inserted in the device. According to the blood occlusion device, a blood vessel can be conveniently penetrated, and blood occlusion can be performed after the blood vessel is penetrated, operation is simple, blood flow can be intermittently controlled,blood vessel cementation can be prevented, the blood flowing direction can be controlled when the blood flow is intermittently controlled, and the operation view cannot be sheltered by blood.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a blood flow blocking device for preventing blood vessel adhesion. Background technique [0002] In operations such as the liver, it is necessary to block the blood flow to control the bleeding during the operation. In the existing blood flow blocking technology, the commonly used method is complete blood flow blocking, that is, the Pringle method. The common practice is: use A 13-gauge urinary catheter or a thinner tape bypasses the hepatoduodenal ligament, and then tightens the catheter or tape with a vascular clamp, but doctors sometimes mistakenly think that the vascular clamp has tightened the tape, but the vascular clamp has fallen off, resulting in The blocking effect is not obvious, resulting in excessive bleeding, and if the aortic clamp is used to clamp the aorta to block the blood flow, the inner wall of the blood vessel will be adhered over time. Therefore, d...

[0002] In operations such as the liver, it is necessary to block the blood flow to control the bleeding during the operation. In the existing blood flow blocking technology, the commonly used method is complete blood flow blocking, that is, the Pringle method. The common practice is: use A 13-gauge urinary catheter or a thinner tape bypasses the hepatoduodenal ligament, and then tightens the catheter or tape with a vascular clamp, but doctors sometimes mistakenly think that the vascular clamp has tightened the tape, but the vascular clamp has fallen off, resulting in The blocking effect is not obvious, resulting in excessive bleeding, and if the aortic clamp is used to clamp the aorta to block the blood flow, the inner wall of the blood vessel will be adhered over time

Therefore, during the operation, the aortic clamp should be loosened according to the specified time interval. When the aortic clamp is loosened, blood will flow out of the aorta, which will increase the blood loss during the operation and increase the risk of the operation.

And after the aortic clamp is loosened, a large amount of blood will flow into the surgical field to block the surgical field. At this time, a blood-sucking operation is required, which is cumbersome, prolongs the operation time, and further increases the risk of the operation. The comparative application number is 201711057627.0 According to the provided design, the design can block the blood flow and increase the sealing of the blocked blood flow, but it is more troublesome when penetrating into the blood vessel
