Summary
A novel circular retractor system, SpineGate, offers adjustable working space for minimally invasive spinal surgery. This system provides a flexible and stable surgical environment, improving patient outcomes in endoscopic discectomy procedures.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Minimally Invasive Surgery
Background:
- Minimally invasive spinal surgery, such as microendoscopic discectomy, requires specialized retractors.
- Current tubular retractors have limitations in flexibility, stability, and workspace accessibility.
- Restricted working space is a common challenge in endoscopic spinal procedures.
Purpose of the Study:
- To introduce the technical aspects of a newly designed circular retractor system (SpineGate) for endoscopic and microsurgical spinal interventions.
- To present the initial clinical outcomes of the SpineGate system in a series of patients undergoing spinal procedures.
Main Methods:
- The SpineGate system features a circular base plate with variable-length valves.
- Valves can be fixed in any direction within the 360-degree base plate, allowing adjustable workspace.
- The system is autoclavable, easy to handle, and does not require an additional fixation device.
Main Results:
- The SpineGate retractor system was successfully utilized in 20 consecutive patients.
- No complications or instrumental malfunctions were reported during the procedures.
- All patients reported good to excellent relief from their preoperative symptoms.
Conclusions:
- The SpineGate circular retractor system provides a continuously adjustable and stable working space for endoscopic and microsurgical spinal interventions.
- The system is safe, easy to handle, and effective in improving patient-reported outcomes.
- SpineGate represents a promising advancement for minimally invasive spinal surgery.
