Standard suturing is an inevitable but time-consuming procedure in all surgical operations. In minimally invasive (MI) surgery, since the complex knot-tying maneuvers are extremely tedious, suturing is even more challenging. Knotless fixation implants are, therefore, developed to eliminate the conventional suturing procedure in surgical operations. Barbed sutures [1], surgical staples, and self-closing clips [2] are widely used in open surgical operations. Moreover, special surgical systems such as the Endo Stitch device, the SILS Stitch articulating device, and the Multifire Endo GIA stapler are designed to replace sutures in a variety of MI operations. These devices, however, are not suitable for precise MI surgery in small operation sites since they require considerably large insertion holes and extensive operating cavities. A novel surgical barbed staple and its insertion system, to be used in precise MI operations, are introduced in this work.

The idea of a barbed staple is...
