Safety: buckle locking device, safer in clipping: Anti-slip off and anti-collapse and opening design: Able to maintain flexible ligation stump; non-absorbable materials, antibacterial, non-toxic and no human tissue rejection. Reliable: The tactile sensing should be in the close mode and safety should be felt; clipping and closure are more completely; no developing or artifacts on X-ray, MRI and CT examination; no tissue adhesion or eschar; hinge+bow peg leg, large in the extension scope of ligation. Fast: Effective capture and ligation target, reduction of separation of the ligation issue region; non-nail-off design, save operation time and can replace the traditional silk ligature; reversing device, to wear suitable surrounding tissue, save in operation time.
