Pull-off characteristics of double-shanked compared to single-shanked ligation clips: an animal study.

ABSTRACT:

Background

The use of surgical ligation clips is considered as the gold standard for the closure of vessels, particularly in laparoscopic surgery. The safety of clips is mainly achieved by the deep indentation of the metal bar with a high retention force. A novel double-shanked (DS) titanium clip was compared to two single-shanked clips with respect to axial and radial pull-off forces.

Methods

In a porcine model (8 animals, 51±1 kg), arteries were prepared immediately after euthanisation, assigned to either a medium (2-4 mm; n=120) or a medium-large (3.5-7 mm; n=120) clip size group, and clipped with the appropriate clip size. After dissection, axial and radial pull-off forces were measured.

Results

The axial pull-off force of the DS-Clip was higher than one single-sh
