Shira 3-Jaw Microvascular Clamp — stainless steel, top view

Patented Innovation

The 3-Jaw
Microvascular Clamp

Traditional 2-jaw clamps allow vessel rotation under the microscope — a leading cause of anastomotic failure. Shira's patented 3-jaw design distributes clamping force uniformly around the vessel circumference, eliminating rotation and reducing thrombosis risk.

Novel Microvascular Clamps to Aid Trainee Surgeon Education: Smarter Than Acland Micro Clamps?

AIIMS New Delhi & University of Rochester, USA


Key Findings

  • 0% backwalling with 3-Jaw vs 30.8% with Acland
  • 0% clamp flipping needed vs 38.5% with Acland
  • Anastomosis time significantly shorter (p = 0.007)
  • Lower need for surgical assistance (p < 0.001)

A novel, innovative clamp with vessel eversion feature for end-to-end microvascular anastomosis

AIIMS Jodhpur, India


Key Findings

  • First clinical report of 3-jaw vessel eversion design
  • Full posterior wall visibility with no clamp repositioning
  • Directly addresses backwalling (21.7%) & incomplete bites (19.6%) — the two leading Acland failure modes
  • Non-glare surface reduces operating microscope interference
