Background:

Liver parenchyma dissection is a critical step in hepatic surgery.
Traditional methods can be complex and costly.
Need for simpler, cost-effective dissection tools.

Purpose of the Study:

To present a novel, inexpensive suction knife for blunt dissection of liver parenchyma.
To describe the device and its application in surgical procedures.

Main Methods:

Development of a suction knife from an ordinary suction tube.
Utilizing the suction knife for blunt dissection during liver surgery.
Successful application in a small cohort of patients.

Main Results:

The suction knife proved to be a simple and inexpensive alternative.
The device was used successfully in six patients for liver parenchyma division.
No complications were reported in the presented cases.

Conclusions:

The suction knife is a practical and cost-effective tool for liver parenchyma dissection.
This method offers a safe and efficient alternative for hepatic surgery.
Further studies may explore wider applications and long-term outcomes.
