Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical appliances, and particularly relates to a portal vein suspension belt. BACKGROUND

[0002] With the innovation of minimally invasive technology, abdominal surgery is converted from the past open surgery to the present laparoscopic / robotic surgery. Minimally invasive surgery is often tricky when facing the operation around the blood vessels. During the medical operation, the blood vessels need to be suspended to avoid affecting the operation.

[0003] The portal vein is characterized by thin wall and large blood flow, so slight carelessness during the operation can easily lead to vein rupture and cause massive hemorrhage.

[0004] The blood vessel sling on the market is usually an arterial sling, and when used for the portal vein, the contact area between the suspension belt and the blood vessel is small, and the blood vessel is easily deformed during suspension, leading to blood flow interruption. Therefore, a blood vessel sling specially used for the portal vein is needed to meet the current operation requirements. UTILIZY MODEL CONTENT

[0010] Further, the end of the suspension rope away from the suspension piece is provided with a pull ring, which facilitates the pulling of the suspension rope to pass the suspension rope through the gap between the portal vein and the internal organs.

[0011] Further, the suspension rope has multiple specifications, and the pull ring has multiple types of colors, and the color of the pull ring corresponds to the specification of the suspension rope, which facilitates the medical staff to quickly take out the required specification of the suspension band according to the actual operation.

[0033] In an embodiment, during the operation, the door vein vessel 3 needs to be suspended. The doctor manually or by using a medical robot inserts one end of the suspension rope 2 into the gap between the door vein vessel 3 and the internal organs of the human body until the suspension piece 1 is located directly below the door vein vessel 3. Then, the two suspension ropes 2 on both sides of the suspension piece 1 are pulled at the same time, so that the suspension piece 1 pulls the door vein vessel 3 upward to achieve the suspension of the door vein vessel 3.
