Introduction
The liver is the organ with the largest blood volume in the abdominal cavity. Hemostasis during liver lobectomy has always been the biggest intraoperative challenge in the past. Therefore, in order to reduce surgical bleeding, various techniques have evolved, among which the Pringle maneuver is the most commonly used. Anatomically, the blood vessels entering the liver are the hepatic artery and hepatic portal vein, which run together with the bile duct to form the Portal triad.
Pringle maneuver uses clamps to clamp the Portal triad before starting the liver lobectomy to temporarily block the blood flow supplying the liver, which can greatly reduce intraoperative bleeding. With the advancement of medicine, laparoscopic surgery has been continuously promoted, and laparoscopic liver lobectomy has been gradually developed. Performing the Pringle maneuver under laparoscopy has always been a question for surgeons because it may involve an additional wound for the patient and may cause intraoperative space obstacles.
This invention mainly takes into account the following features of Pringle maneuver during surgery:
1. It operates in the abdominal cavity. The method is simple and does not take up space, and does not require adding a hole in the abdominal wall.
2. Really blocks the blood flow to the liver porta without causing damage to the porta hepatis.
3. Only after the portal triad is separated for the first time, there is no need to do the same action again and again, thereby reducing damage to the portal of the liver.
4. To ensure that the liver will not cause ischemic damage to the liver after the Pringle maneuver, the surgery is performed with intermittent blockade. This invention can be easily operated to achieve tightening and relaxing states, thereby achieving the purpose of intermittent blocking of blood flow during surgery.
Features / strengths
1. The components are simple in design, easy to disassemble and assemble, and the operating room is easy to disinfect.
2. The components are small in size and do not cause space obstacles.
3. It can be operated almost inside the laparoscope and does not require extra laparoscopic holes.
4. The operation is simple and easy to get started, and it does not take much time to operate repeatedly.
5. It can completely block the blood flow and achieve the effect of Pringle maneuver.
