Precise hepatic parenchymal transection with minimal bleeding

Liver surgery is one of the most demanding disciplines in soft tissue surgery. One of the primary goals of liver resection is to operate with as little bleeding as possible and at the same time to preserve vessels and bile ducts.

The ultrasonic technology of the Söring Macro instruments leads to a gentle and precise fragmentation of liver parenchyma. By the use of cavitation and mechanical effects of the ultrasound solid connective tissue structures of vessels and bile ducts are protected.


  • tissue selectivity for safe preparation with minimal blood loss
  • better view of the operating field due to optimal irrigation and effective aspiration

Main indications in liver surgery

  • liver cell carcinoma (hepatocellular carcinoma (HCC))
  • bile duct carcinoma (cholangiocellular carcinoma (CCC))
  • liver metastases (e.g. colorectal liver metastases)
  • partial living donor liver transplant (LDLT)

High-frequency coagulation function

In addition to the proven ultrasonic technology, the Macro instruments of the 94 HF series offer a monopolar high-frequency (HF) coagulation function. It can be conveniently activated by hand and allows the surgeon to independently coagulate small vessels and to stop bleedings during surgery.

Laparoscopic ultrasonic dissection

Laparoscopic liver resection is a young, aspiring technique of modern surgery. Compared to open surgery, it is associated with less blood loss, fewer complications and shorter recovery times.1
