● Material and mechanical structures of absorbable vascular clips affect its hemostatic efficiency.

● The tooth shape, tail end, and closure of vascular clips are the main direction of mechanical structure improvement.

● The coating of the vascular clips can regulate the degradation rate and improve hemostatic efficiency.

● Reasonable mechanical properties and degradation rate are the main development direction for absorbable vas cular clips.

Abstract

Minimally invasive surgeries are widely applied due to the advantages of small surgical wound, short postoperative recovery period, and low surgical infection rate. In minimally invasive surgery, vascular clips play a significant role in hemostasis and managing the direction of blood flow, ensuring the success of surgical procedures. The mechanical structure and manufacturing materials of vascular clips have an important influence on its clinical application effect. In this paper, we classify and summarize the mechanical structure and manufacturing materials of the currently available vascular clips worldwide, and then analyze the hemostatic coating materials of vascular clips. Besides, we also summarize the shortcomings of the existing vascular clips and propose a coat-absorbable vascular clip with future research potential.

Keywords: Vascular clips, mechanical structure, absorbable material, mechanical properties, coating
