Bulldog Clamps
Bulldog clamps are small, spring-loaded clamps that temporarily stop the flow of blood in a vessel without needing to be held. They let the surgeon work on a vessel while keeping the field dry. Medfort makes the classic patterns in straight and angled versions, plus atraumatic clamps and clip applying forceps (codes SI-010201 to SI-010223).
Where they are used
They are used in vascular surgery, kidney surgery, transplant surgery, plastic and microsurgery, and any operation where a vessel must be temporarily closed.
Our range
- Bulldog clamps: Dieffenbach, John Hopkins and Diethrich (straight and angled)

Material and finish
All instruments in this category are made from surgical grade stainless steel to AISI, ASTM and DIN standards, imported from Germany, Japan and France. Each piece is heat-treated to the right hardness for its job, then polished to a satin finish that reduces glare under theatre lights. Joints are fitted by hand so they move smoothly without play, and every instrument is checked before it is packed.
How to choose
Choose the clamp size to suit the vessel: small clamps for fine vessels and larger clamps for bigger arteries. Atraumatic jaws protect the vessel wall. Angled clamps reach vessels that are hard to approach straight on. Use applying forceps to place and remove clamps precisely.
Quality control
Every Medfort instrument passes several checks before it leaves our workshop. We check the hardness after heat treatment, inspect jaws, teeth and serrations for correct alignment, test that ratchets lock and release smoothly, and look for any surface defects. Finished instruments are passivated to improve corrosion resistance, then cleaned, marked and packed.
Care and sterilization
Rinse instruments straight after use so blood and tissue do not dry on. Open all joints, then clean them by hand or in a washer-disinfector with a neutral pH detergent. Rinse, dry thoroughly and lubricate hinges with instrument milk. All items are suitable for standard steam sterilization (autoclave). Inspect them regularly, and repair or replace any that are worn or damaged.
