| Summary: | Introduction: Robot ‑assisted surgery is becoming increasingly popular and its application is expanding
to various spinal surgical procedures, including endoscopic spinal surgery.
Aim: The aim of this study was to describe a novel small parallel orthopedic surgical robot and evaluate
its feasibility in assisting surgeons during percutaneous lumbar laminectomy on cadaveric specimens.
Materials and methods: The authors of the study developed a new orthopedic surgical navigation
system (R ‑Pharos, Rossum Robot Co., Ltd, Beijing, China), consisting of a navigation cart and a hybrid
serial ‑parallel bedside robotic arm. The system is equipped with interactive software for selecting and
planning the percutaneous lumbar laminectomy target and path. A cadaveric specimen was selected
for a right ‑side partial laminectomy at L4. During the procedure, the surgeon used the robotic arm to
guide the saw to the target lamina and perform the percutaneous resection. Postoperative cone beam
computed tomography (CBCT) and endoscopic assessments were used to confirm the resection outcome.
Results: After optimizing the precision of the small parallel orthopedic surgical robot to 1 mm, it was
shown to meet the navigational requirements for percutaneous lumbar laminectomy. The surgeon utilized
the interactive software to design the resection range and path for the right L4 lamina which was suc
cessfully resected, as confirmed by endoscopic observation. A postoperative CBCT scan revealed that
the resection area precisely matched the preoperative design.
Conclusions: This study demonstrated that the small parallel orthopedic surgical robot was capable of
preoperatively planning the lamina resection area and could assist the surgeon in performing percutane
ous lumbar laminectomy with high navigational precision. |
