Franklin-Silverman Modified Fuchs Biopsy Needle 130mm

Franklin-Silverman Modified Fuchs — 130mm Biopsy Needle

The 130mm shaft Franklin-Silverman is the obese-patient cutting-biopsy variant — extended length for percutaneous liver biopsy in patients with thicker abdominal walls or for retroperitoneal-organ biopsy where the lesion sits deeper than the standard 105mm reach. The cutting-biopsy principle is identical to the 105mm variant; only the length differs.

The retroperitoneal-biopsy applications

Retroperitoneal masses (lymphadenopathy, adrenal masses, pancreatic head lesions) may require percutaneous biopsy for tissue diagnosis. Image-guided (CT or ultrasound) biopsy uses the 130mm Franklin-Silverman to reach the retroperitoneal location through the anterior abdominal-wall approach. The cutting biopsy provides the intact tissue architecture needed for lymphoma subtyping or for adrenal-mass characterisation when imaging features are equivocal.

The image-guided biopsy workflow

Modern percutaneous biopsy is overwhelmingly image-guided — real-time ultrasound for superficial-and-abdominal targets, CT for deeper or more complex anatomy. The 130mm Franklin-Silverman is compatible with both guidance modalities; the longer needle accommodates the CT-table-to-target geometry that ultrasound-guided procedures rarely require.
