摘要
目的探索先端可吸收半倒线装置用于肺内小结节穿刺定位的可行性。方法将21个猪肺平均分为3组,分别采用先端半倒刺线、微弹簧圈、带钩钢丝对其进行穿刺定位,判断是否成功,然后通过手摇式拉力架测量定位物的锚定力。所有定位操作均采用“预充式”定位法完成。6名专家独立评估先端半倒刺线、微弹簧圈、带钩钢丝的柔韧性。结果3组全部21次定位均成功。先端半倒刺线组的锚定力明显优于微弹簧圈[(1.089±0.288)N VS(0.066±0.015)N,P=0.000],与带钩钢丝锚定力相似[(1.089±0.288)N VS(1.190±0.279)N,P=0.519]。6名专家均认为先端半倒刺线柔韧度与微弹簧圈相似明显优于带钩钢丝。结论离体实验显示,采用先端可吸收半倒刺线装置穿刺定位肺内小结节具有先端锚定力强、不易脱落、柔韧性好的优点,且无金属异物残留风险,具有临床应用前景,值得进一步研究评估。
Objective To evaluate an apex semi-barbed absorbable suture localization device for small pulmonary nodules.Methods Twenty-one pig lungs were evenly divided into three groups:a semi-barbed absorbable suture group,a microcoil group,and a hookwire group.Semi-barbed absorbable sutures,microcoils,and hookwires were used in respective groups for lung puncture localization.Success of localization was then assessed,and the maximum anchoring force of the localized object was tested by means of a hand-drawn tension frame.All localization operations are performed using a"prefilled"localization method.Six experts evaluated the three groups.Results All 21 positioning operations in the three groups were successful.The maximum anchoring force of the apex semi-barbed absorbable suture group was significantly better than that of the microcoil group[(1.089±0.288)N vs(0.066±0.015)N,P=0.000]and the hookwire group[(1.089±0.288)N vs(1.190±0.279)N,P=0.519].All six experts considered that the flexibility of the absorbable apex semi-barbed suture was similar to that of the microcoil,which was significantly better than that of the hookwire.Conclusions Apex semi-barbed absorbable sutures for localization at small nodules in the lungs exhibit strong anchoring force,good flexibility,low dislocation probability,and no risk of metal residue,and have good potential for clinical application.Further evaluation is warranted.
