Description

Blood flow temporary blocking device

The present invention relates to a blood flow temporary blocking device, and more particularly to a blood flow temporary blocking device for temporarily blocking blood flow in a specific region of a body.

During the surgical procedure, the surgeon needs to carefully control the amount of bleeding in the patient. Therefore, a variety of hemostasis methods have been developed, among which Pringle maneuver is the most common. The Pringle hemostasis method is often used in abdominal surgery, such as liver surgery. In general, the traditional operation method needs to distinguish the portal triad, and then the hemostatic forceps clamp to restrict the hepatic artery and the hepatic portal vein. Blood flow, in addition, in order to prevent liver ischemia for too long, resulting in impaired liver function, the surgical process needs to release the blood flow restriction area in time, so that the blood flow is recycled to the organs again. However, the procedure of repeating the hemostasis is cumbersome and time consuming, because each time the hemostasis process is repeated, it is necessary to re-divide the door tube triple to limit the blood flow.

Nowadays, the traditional surgical methods have gradually been replaced by laparoscopic surgery, which has become the main trend of the main surgery. The main advantage is that the surgical wounds are small, which can reduce the risk of infection and shorten the disease. The recovery period of the person; in addition, compared with the traditional surgery, laparoscopic surgery can more clearly see many dead angles in the abdominal cavity, for example, the right posterior liver lobe and the deep left liver. In the operation of laparoscopic surgery, in addition to the need for a good field of view, appropriate holes are required for placement of the photographic lens and associated surgical instruments. Therefore, under the limited operating space of the laparoscopic operation, the setting of the operation hole and the equipment and instruments placed therein will directly affect the smoothness of the operation.

Therefore, when the traditional Pringle hemostasis is applied to laparoscopic surgery, there are many restrictions. For example, in order to insert a hemostatic forceps, an operation hole is required in the patient's abdomen, which increases the patient. Abdominal wall wounds; in addition, laparoscopic surgery has limited space. If the operation is performed by the traditional Pringle hemostasis method, it will often cause surgery space obstacles. In addition, because the operation process requires intermittent hemostasis until the operation is completed, if the above tradition is The cumbersome and time-consuming hemostasis method is more inconvenient when applied under laparoscopic surgery.

In view of this, there is a need in the art for an improved blood flow temporary blocking device for use in current abdominal surgery to improve or help limit blood flow to organs.
