balloon dissector

Full Definition

A balloon dissector is a specialized instrument featuring an inflatable balloon tip that creates blunt dissection planes in minimally invasive surgery. Most commonly used in extraperitoneal procedures, the device is inserted deflated and then gradually inflated to separate tissue layers without sharp dissection. This technique is particularly valuable in hernia repair and retroperitoneal surgery, where it helps establish working space while minimizing tissue trauma and bleeding risk.
