After more than ten years, Shanghai Dongfang liver and gallbladder developed the first domestic liver blood vessel blood flow control equipment to solve the problem of "handmade version" blood vessel blocking problems

A multi -purpose vascular blocking equipment can solve the problem of "handmade" blood vessel blocking problems. A few days ago, the reporter learned from the Third Affiliated Hospital of the University of Military Medical Medicine (Shanghai Oriental Hepatobiliary Surgery Hospital) that Liu Hui, the deputy dean of the hospital, innovated liver surgery blood flow blocking technology, and successfully developed the first domestic liver blood vessel blood flow control for more than 10 years. Equipment, which makes liver blood vessels control and release more secure and more convenient.

In the Anting Hospital of Shanghai Oriental Hepatobiliary Surgery Hospital, Liu Hui was performing part -time laparoscopic hepatic hepatic hepatoscopy for a patient. During the operation, multiple blood vessels in the liver needed to prevent bleeding. At the scene, the doctor gently squeezed the handle to complete the operation of blood flow blocking.

Surgery is recognized as the first choice method for liver cancer treatment, but liver surgery is difficult and risky. Blood flow control is a key technology to ensure the success of the surgery. The decrease in the amount of bleeding and the reduction of the blocking time can significantly improve the prognosis. Therefore, bleeding during control is a key technology for hepatic resection surgery.

"Originally during the operation, we needed the first assistant to lift the liver, the second assistant pressed the gastrointestinal and subordinates. Block. Now that a doctor can do it with one hand after preset controller. "Liu Hui introduced that the equipment can not only shorten the operation time, reduce the difficulty of operation, but also quickly achieve liver blood flow control.

In 2011, Liu Hui's research team began to develop the research and development of liver vascular blocking related equipment to achieve precise blocking of liver vascular streaming and interpretation.

"Ten years ago, when the hospital first introduced the ultrasonic knife, Academician Wu Mengchao explained the task of developing the hepatic blood vessel blood flow control equipment to replace the manual operation." Liu Hui said that the equipment seemed simple, but the development process was quite expensive. First of all, you must measure all the hepatic door flow and the length of the blood vessels in the human body to design the equipment length. In addition, the selection of materials is also quite particular. Direct contact with human organs need to use flexible materials. If the material is too hard, it will cause endometrial wall damage and easily form thrombosis.

After iteration of the 16 version of the sample, the device changed the concept of traditional surgery and abandoned the method of preventing blood vessels in the past. When liver surgery enters the eager era, after using this device, it will be blocked after encountering unavailable bleeding, which can maximize the blood vessels in the whole liver and global watershed, avoid heat ischemia and re -injection, and achieve optimization to optimize the optimization Oversure protection, minimal treatment of trauma.

It is reported that through the adjustment of product specifications, it is expected to be promoted and applied in the operation of kidney, heart, and vascular surgery that requires blood flow control. Relevant innovation improvements have applied for 32 patents, 9 of which have been authorized.
