Summary
A novel soft trocar enables simultaneous insertion of endoscopic and surgical tools through a single incision for varicose vein treatment. This device simplifies subfascial endoscopic perforator surgery (SEPS) with no reported complications.
Area of Science:
- Minimally Invasive Surgery
- Surgical Device Development
- Vascular Surgery
Background:
- Development of a novel y-shaped soft trocar for endoscopic subcutaneous surgery.
- Evaluation of the trocar in subfascial endoscopic perforator surgery (SEPS) for lower leg varicose veins.
Purpose of the Study:
- To assess the efficacy and safety of a new soft trocar in SEPS.
- To determine if the trocar facilitates simultaneous instrument and endoscope insertion.
Main Methods:
- SEPS performed on 12 patients using the soft trocar through a 2-cm incision.
- Trocar inserted into the subfascial plane, followed by CO2 insufflation.
- Perforating veins divided using endoscopic instruments via the trocar's port.
Main Results:
- No major device-related difficulties were encountered during the procedures.
- No significant wound complications were reported in the patient cohort.
Conclusions:
- The soft trocar effectively allows simultaneous access for endoscopic and surgical instruments via a single incision.
- This innovative device shows potential for broader applications in various endoscopic surgical procedures.
