Abstract
Purpose: We report here a new instrument device that provides automatic suture ligation and closure device for blood vessels and tissues
Materials and methods: To evaluate the efficacy of this instrument, 6 surgeons performing surgery tied 3 knots using classical method and then using the automatic ligation and closure device. The times required to tie each knot and the knot strength were recorded and compared statistically.
Results: Comparing the 2 knotting methods, the time spent tying the knots was shorter with the knot-tying instrument in all 3 trials and the knot strength was statistically higher with the knot-tying instrument.
Conclusion: This automatic ligation and closure device can be used for all knots in surgery when classical knotting is difficult.
