Description

Hand-free minimally invasive liver suspension device for laparoscopic surgery

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a hand-free minimally invasive liver suspension device for laparoscopic surgery.

Background

In the operation of stomach, esophagus, pancreas, etc., the left outer lobe of the liver needs to be suspended in order to fully expose the operation field, especially when the patient is obese or the left lobe of the liver is hypertrophic, the liver suspension is very important. In the traditional liver suspension, an assistant often uses a laparoscopic liver retractor (a golden finger liver retractor), a fan-shaped clamp and other instruments to lift the liver to the upper right, an operation hole of 5-10mm needs to be additionally arranged on the abdominal wall, the minimally invasive effect of the laparoscopic surgery is weakened, and when the surgery time is too long, the laparoscopic liver suspension seriously occupies human resources and increases the physical consumption of the assistant. Although the Nathanson liver retractor already exists, it is expensive to purchase, time and labor consuming to install, still requires a small incision in the abdominal wall, and is too small in the interface with the liver for many studies to show that it can cause damage to the liver.

The liver suspension method using various disposable suture, vascular clamps, biological glue, drainage tubes, catheters and other materials can avoid adding an additional abdominal wall operation hole and the inconvenience caused by holding the retractor by an assistant for a long time, but has high cost, time waste and labor waste. In addition, when the liver is suspended by using the above materials, the suspension cannot be temporarily released during the operation, and the liver parenchyma and blood vessels and bile ducts are easily damaged by the action of the materials such as sutures, vascular clamps, drainage tubes and the like on the liver for a long time.

Currently, there are several patents that have devised liver suspension devices and methods. Patent document CN204744271U discloses a liver suspension device for laparoscopic surgery, which does not need to add additional incision, but when using the device, the coronary ligament of the liver needs to be separated, and the suture needs to be passed out of the abdominal cavity to fix the device, so the operation is complicated, and there is no substantial difference compared with the liver suspension method using the drainage tube, catheter and other materials clinically. The patent document CN211534580U discloses a liver suspension device for laparoscopic surgery, which can reduce the pressure on the liver by increasing the contact area between the device and the liver, but still needs an additional 5-10mm abdominal cavity operation hole. Patent document CN111388032A discloses an organ suspension device for endoscopic surgery, but it has a complex structure, complicated operation, poor controllability, and limited clinical transformation value.

Therefore, the existing liver suspension device and method cannot meet the requirements of real minimal invasion and time and labor saving, and have various defects, and a liver suspension device which is more minimal invasion, safe, labor-saving and low in cost is urgently needed in abdominal surgery.
