“…MS also can be used for digestive tract anastomosis ( 5 – 8 ), cystostomy ( 9 ), establishment of an animal model of tracheoesophageal fistula ( 10 ), and vascular anastomosis ( 11 – 15 ). The magnetic anchor technique (MAT) is an important magnetic surgical technique ( 16 ) that has been used in laparoscopic surgery ( 17 , 18 ), thoracoscopic surgery ( 19 ) and endoscopic submucosal dissection ( 20 , 21 ) and offers the advantages of reducing trauma and optimizing surgical operations.…”

Background and objectivesA 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 methodsThe 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.ResultsThe 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.ConclusionsThe 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.

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 98%, 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. In conclusion, Y-Z MTIVAP was associated with a significantly improved puncture success rate and shortened operation time, and thus, has important clinical application value.
