"One way of doing minimally invasive surgery uses cutting trocars — and with that comes scarring, trocar site pain, and hernia formation," explained Dr. McCarus, noting that newer technology has emerged in the form of bladeless trocars with no cutting tips. The bladeless trocar penetrates by separating tissue fibers, thereby producing a smaller fascial defect and allowing repositioning of the tissue at port site after removal of the implement.

McCarus医师指出，切割式的套针是侵犯性最低的手术法之一，但是其所带来的负面效应也不少，包含疤痕、套针插入部位疼痛及疝气等；现在，新的技术所使用的套针不但没有刀刃，也没有锐利的切割尖端；这种无刀刃的套针，以分离纤维组织的方式作穿刺，因此对筋膜的伤害最低，且在手术完成后，所穿刺的组织部位可以自行再定位，不需缝合。
