Autologous Cancellous Bone Dowels | Minimally Invasive 8-Gauge Access | 1 Minute Graft Retrieval | Preserves Native Microarchitecture

PercuGraft Screw Dowel Harvester — minimally invasive autologous bone dowel retrieval instrument
Structural Autograft, Minimally Invasive

Structural autograft for fusion, defects, and more.

PercuGraft Screw Dowel Harvester tip — minimally invasive 8-gauge access for retrieving intact cancellous bone dowels

PercuGraft™ retrieves intact cancellous bone dowels through a minimally invasive 8-gauge access point, preserving the native trabecular microarchitecture and microvascular structure that conventional particulate harvesting disrupts.

Multiple autograft dowels can be retrieved in roughly one minute per core, and PercuGraft pairs naturally with particulate grafts to extend autologous material across fusion, bone defect, and void-filling procedures — all without the morbidity of an open iliac crest harvest.

Key Benefits

Designed for efficient, autologous graft retrieval.

Autologous Cancellous Dowels

Retrieves intact, structural cancellous cores directly from the patient — a true autograft with living osteogenic, osteoinductive, and osteoconductive elements.

Minimally Invasive 8-Gauge Access

Percutaneous entry through a small 8-gauge portal avoids the incision, blood loss, and donor-site morbidity associated with open iliac crest harvest.

1 Minute Graft Retrieval

Each intact dowel is recovered in roughly one minute, allowing multiple cores per procedure with minimal added OR time.

Preserves Native Microarchitecture

Retains trabecular geometry and the native microvascular scaffold that supports cellular ingrowth — structure that particulate harvest techniques destroy.
