Weck® Hem-o-lok® Polymer Locking Ligation System

Security you can feel from the #1 selling locking polymer clip

Why have surgeons trusted the Hem-o-lok System for more than one million patients? As the #1 selling locking polymer clip, the Hem-o-lok System offers quality, reliability, and performance in clip security.

Designed for confidence

Featuring a first-of-its-kind locking mechanism and distinct tactile feedback, the Hem-o-lok System gives surgeons the confidence of knowing they’ve locked securely on the patient vessel.

A history with robotic laparoscopy

Since 2007, we’ve collaborated with Intuitive Surgical to provide the Hem-o-lok System for use with the da Vinci® Surgical System.

Proven performance

Backed by 84 peer-reviewed articles, no other polymer clip stands on so much evidence to support clinical and financial outcomes. Based on an ex-vivo study*, Weck® Hem-o-lok® polymer clips provide unparalleled security compared to Ethicon LIGAMAX 5, Ethicon LIGACLIP® ERCA 10 mm, and Covidien Endo Clip III in three common clip failure modes. Hem-o-lok Medium/Large clips have:

  • At least 5 times greater clip retention in lateral pull-off force
  • At least 1.8 times greater leak resistance in leak pressure testing
  • At least 1.3 times greater clip retention in axial pull-off force

Versatility to meet your needs

Hem-o-lok Clips come in a range of sizes indicated to ligate structures from 2 mm to 16 mm.

The original polymer locking clip


Cutting-edge design

  1. Bosses are designed to retain clip in applier jaws.
  2. Integrated teeth interface with the vessel and are designed to prevent slippage.
  3. Bow-shape design allows removal with appropriate instrument.
  4. Hinge allows flexibility in clip placement prior to clip locking.
  5. Locking mechanism provides tactile feedback and secure closure.
  6. Nonabsorbable polymer is inert, nonconductive, and radiolucent; it does not interfere with CT, MRI, or X-ray diagnostics.

Because the Hem-o-lok System is a cool ligation system, there's no chance of thermal spread to vital structures – a common concern of many surgeons when using energy-based ligation solutions.

The Hem-o-lok System is available in four sizes: Medium, Medium-Large, Large, and Extra-Large. Ordering information in catalog
