    Abstract
  •   Objective  To develop a pulling device using magnetic positioning to optimize the procedures of repairment of donor liver from organ donation.  Methods  The pig liver specimens were used to measure the pull force of repairment of donor liver, magnetic spiderman was developed based on the measurement results. The magnetic spiderman was applied to simulate the repairment of donor liver from organ donation on the pig liver specimens. The effectiveness of magnetic spiderman was also evaluated.  Results  The pulling force was required all less than 2 N during the repairment of donor liver. The magnetic spiderman was successfully manufactured. The magnets of magnetic spiderman could generate 3 N magnetic forces with paramagnetic basin of hepatic repairment. The self-retraction pull wire of the magnetic spiderman could provide 2.5 N pulling forces. The magnetic spiderman was successfully applied to the simulated experiment of repairment of donor liver from organ donation in 6 cases. The operation time was (54±5) min. No clip slippage, displacement and slippage of the base occurred during the operation. With the cooperation of multiple magnetic spidermen, the remaining surgical procedures were performed by one single surgeon except for the vascular ligation.  Conclusions  The magnetic spiderman has small volume and implements flexible positioning, can perform pulling operation and not take up operational space. It can effectively optimize the procedures of repairment of donor liver from organ donation and reduce the quantity of surgeons.
