摘　　要：目的设计一种可实现多种功能的连续活检钳,仅需将活检钳插入内镜活检通道一次,即可活检获得多块活体组织。方法重新设计活检钳钳头,钳头采用多瓣式弹性钳体结构;该特殊设计的钳头钳取组织块后,可通过负压吸引将组织块经钳身内部吸至操纵部内的回收管,从而实现连续活检。结果采用外径与内镜活检通道直径相容的塑料细管测试,证实可快速吸引已经常规活检钳钳取的人体组织块。结论本设计结构简单,方法可行,可实现连续快速活检并可拓展多种功能。Objective To design a multi-functional continuous biopsy forceps,which can obtain multiple lumps of tissue via inserting the tunnel of the endoscope only one time.Methods The binding clip was redesigned which was equipped with many lamellas binding clip,and the binding clip included the elasticity pincers body of leaning setting.After the tongs of the special design were taken out of the tissue block,the tissue block could be absorbed by the negative pressure to control the recovery tube inside the control department,so as to realize the continuous biopsy.Results Quickly attracted has been applied to obtain viable tissue in the conventional biopsy via testing compatible with the tunnel of the endoscope to suck lump of the tissue.Conclusion The structure of the design is simple,the method is feasible,and it can realize the continuous quick biopsy and extend many functions.
