摘要

摘要: 目的研制一款利用磁定位的牵拉装置，优化器官捐献供肝修整操作。方法采用猪肝标本进行供肝修整操作牵拉力测量，根据测量结果研制磁蜘蛛人，将磁蜘蛛人应用于猪肝标本上模拟器官捐献供肝修整操作，并检测磁蜘蛛人有效性。结果供肝修整操作中所需牵拉力均不超过2 N。成功完成磁蜘蛛人的制造，磁蜘蛛人的磁体可与顺磁性修肝盆之间产生3 N磁着力，磁蜘蛛人的自回缩牵拉线可提供2.5 N牵拉力。磁蜘蛛人成功应用于6例器官捐献供肝修整模拟实验，手术时间（54±5）min。手术过程中未发生夹头滑脱、底座移位、脱落等现象。在多个磁蜘蛛人的配合下，除结扎血管外，术中其余操作均由主刀一人完成。结论磁蜘蛛人体积小巧、定位灵活，能够进行牵拉操作且不占用操作空间，可有效优化器官移植供肝修整操作，减少手术操作者人数。

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.
