In single-port thoracoscopic lobectomy, surgical instruments are likely to collide and interfere with each other. We used magnetic anchor technique to design an anchoring device suitable for thoracoscopic surgery, and verified the safety and feasibility of its use in animal experiments. Ten Beagles were used as models, and magnetic anchor technology was used to assist thoracoscopic lobectomy. During the operation, a self-designed magnetic anchored internal grasper was used in place of the traditional laparoscopic grasping forceps. The operation time, intraoperative blood loss, incidence of postoperative complications, and the effect of intraoperative use of the device were analyzed. All 10 beagles were successfully operated; the mean operation time was 19.7 ± 3.53 min (range 15-26 min), and the postoperative blood loss was < 10 mL. No surgical complications occurred. During the operation, the internal grasper was firmly clamped, the auxiliary operation field was well exposed, and the interference of the main operation hole instruments was effectively reduced. We provide preliminary experimental evidence of the safety and feasibility of magnetic anchor technique-assisted thoracoscopic lobectomy.
