Summary:
UCLA researchers from the Department of Radiology have developed a novel needle-holding clamp for use during minimally invasive procedures.
Background:
Minimally invasive procedures are now widely used for diagnosing and treating subcutaneous and deep tissue targets. These procedures use percutaneous needle insertions rather than large incisions to access targets, and as such rely on image guidance for precise targeting of the intended tissues. Existing methods involve continuous monitoring through repeated imaging to ensure accurate targeting. These techniques use free-hand needle manipulations based on previous three-dimensional scans. This method can result in deviations from the intended trajectory due to factors including patient breathing, body movement, and tissue deformation. These degrees of freedom can result in poor targeting and prolonged procedures, potentially leading to complications and increased healthcare expenditures. There remains an unmet need for an accurate and minimally invasive needle control method that does not require continuous imaging monitoring for improved surgical outcomes.
Innovation:
UCLA researchers from the Department of Radiology have developed a novel needle-holding clamp with a built-in rolling sphere. The design of the clamp allows for precise control and stabilization of the needle during minimally invasive procedures. This innovation allows the needle to remain in its intended position and direction, preventing movement during monitoring and confirmation scans. The device provides an adjustable grip on needles with different sizes, minimizing deviation during procedures. The universal and affordable design of the clamp allows accommodation of different needle sizes and integration into standard medical kits. This technology can revolutionize minimally invasive procedures by providing precise and stable control of needles.
