Abstract
Background and objectives A totally implantable venous access port (TIVAP) is a commonly used intravenous infusion device for patients receiving chemotherapy or long-term infusion therapy. To improve the success rate of one-time insertion of the Huber needle, we developed a novel Y-Z magnetic TIVAP (Y-Z MTIVAP), which we produced using three-dimensional printing technology. Materials and methods The Y-Z MTIVAP includes a magnetic port body and a magnetic positioning device. For testing, we established four venous port implantation models using the two types of TIVAPs and two implantation depth ranges (≤5 mm and >5 mm). Twenty nurses performed Huber needle puncture with the four models, and we recorded the number of attempts required for successful needle insertion, the operation time, and the operator's satisfaction. Results The success rate for one-time needle insertion with the Y-Z MTIVAP was significantly higher than that with the traditional TIVAP at either depth range (100% vs. 75% at ≤5 mm, p = 0.047; 95% vs. 35% at >5 mm, p < 0.001). With increasing implantation depth, the success rate for one-time insertion was significantly reduced with the traditional TIVAP (75% at ≤5 mm vs. 35% vs. >5 mm, p = 0.025), but the success rate with the Y-Z MTIVAP was not significantly affected (100% vs. 95%, p = 1.000). The operation time with the Y-Z MTIVAP was significantly shorter than that with the traditional TIVAP at either depth range (both p < 0.001), and 90% of operators reported that the Y-Z MTIVAP was superior to the traditional TIVAP. Conclusions The theoretical design of Y-Z MTIVAP is feasible, and the preliminary in vitro simulation experiment shows that it can significantly improve puncture success rate and shortened operation time.

Abstract
BACKGROUND There have been no prospective randomized controlled clinical trials evaluating the advantages of the magnetic anchor technique (MAT) used in reduced-port laparoscopic cholecystectomy (LC). The present study evaluated a novel magnetic anchor device designed by the authors. METHODS Between April 2019 and June 2020, 60 patients with gallbladder diseases participated in a single-center, prospective, randomized controlled clinical trial. The patients were randomly apportioned to undergo either 2-port LC assisted by the novel MAT (MAT-2P-LC, experimental group) or conventional 3-port LC (3P-LC, control). The groups were compared regarding operative time, postoperative complications, surgical incision pain score (Wong-Baker), and other indicators. The patients were followed for 2 years. RESULTS The test and control groups were comparable in age, gender, body mass index, and primary disease. No patient in the MAT-2P-LC group was converted to 3P-LC. No patients were converted to laparotomy. On the first postoperative day, the Wong-Baker pain score of the experimental group (1.60 ± 0.67) was significantly lower than that of the control (2.20 ± 0.76; P = 0.002). The groups were statistically similar regarding intraoperative blood loss; operative time; time to leave bed; hospital stay; postoperative pain scores at 1 and 4 weeks; and complications. CONCLUSIONS This rigorous clinical trial shows that the novel MAT used to assist reduced-port LC significantly reduced postoperative pain, but has no obvious advantages in other terms.

Abstract
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.
