Also called micro artery clamp · Micro Vessel Clamp
The jaw curves slightly inward at the tip for extra grip on the thicker, more slippery wall of an artery, where the microvascular clamp uses a straight jaw sized for veins and most arteries.
A microvascular clamp is a small vessel-occluding clamp built to hold a fine artery or vein closed without damaging its wall. The two arms close under their own spring tension rather than a ratchet, so the jaw faces meet at a fixed force instead of being tightened by hand, and that force is set by the spring rather than adjusted by the user. The jaw faces are short, flat or lightly grooved, and lined so the vessel wall is compressed rather than crushed. Clamps are made as single clamps, for one vessel end, and as double clamps carried on a connecting bar so both cut ends of a vessel stay aligned for the join.

Quality control
The inspection step is set by the line you order.
- Economy line
- sample: visual + dimensional
- Clinical line
- sample + boil test
- Premium line
- tighter sample + hardness test
- Executive line
- 100% inspection + laser mark
Finish A color is a second choice, made on top of the line. Colored finishes on request, on any instrument, in addition to the steel line. Evidenced: black · gold · rose gold · blue · rainbow (anodised titanium).
How it is built
- Two-armed body closed by its own spring tension, not a screw or ratchet
- Jaw faces meet at a fixed closing force set by the spring rather than adjusted by hand
- Jaw faces are short, flat or finely grooved, and lined to reduce trauma to the vessel wall
- Made as single clamps and as double (twin) clamps carried on a connecting bar for both ends of an anastomosis
- Straight and curved jaw versions
- No box-lock or finger rings, opened and closed by squeezing the spring arms directly
PatternsSingle clamp · Double (twin) clamp on connecting bar · Straight jaw · Curved jaw
The standard sizes this kind of instrument is made in
52.5 mm overall length, 8 mm (8.6 × 1.3 mm) jaw, Diethrich pattern · 18 mm overall length, 9 mm jaw, Biemer pattern, light closing pressure (~30-40 gf)

This describes the microvascular clamp as an article. 8 other articles in this catalog share it: the sentence above is what separates this one. This describes the article. The steel, the finish and the inspection step are set by the line you order.
Material and quality
| Line | Steel | Origin | Finish | Inspection |
|---|---|---|---|---|
| Economy line | AISI 410 | Pakistani or Taiwanese | satin, passivated | sample: visual + dimensional |
| Clinical line | AISI 420 | Pakistani or German | satin, passivated | sample + boil test |
| Premium line | AISI 420-440C | German or Japanese | fine polish, passivated | tighter sample + hardness test |
| Executive line | AISI 440C | German or Japanese | mirror polish, passivated | 100% inspection + laser mark |
This is the steel each line is made from as standard. A different origin can be supplied on request (a lower grade in Japanese steel, for example), agreed on your order.
Premium is the line where the choice is yours: 420 or 440C, agreed on your order. Economy is always 410 and Executive is always 440C. Those three are the instrument steels. Hollowware and sterilization containers are made in AISI 202 on a Clinical order and AISI 304 on a Premium or Executive one, and they are not offered in the Economy line at all, which is the section above.
True of every order
Instruments are marked to the buyer's requirement (TGI, unmarked, or the buyer's own brand), agreed on the order.
Customized packaging is part of what TGI supplies. Your own printed boxes, your labels, your brand on the pack, or plain export packing, whichever your market needs. The packing for your order is agreed with you and confirmed on the order.
Manufactured under the quality management system covered by TGI's ISO 9001:2015 and ISO 13485:2016 certificates. Certificate numbers and the issuer's registry are on the certification page. Open the certificates
Every batch of steel is ordered to a specified grade and arrives with the mill's own certificate, which identifies the mill and states the grade. TGI checks the material at the factory against its own requirement before it goes into production. That check is TGI's own inspection, not an independent laboratory test.
TGI manufactures in its own factory in Sialkot and also supplies articles made by contracted partner workshops, to TGI's specification. Which applies to a given article is confirmed on your order.
One-year guarantee on Premium and Executive tier instruments, hollowware and sterilization containers: any technical manufacturing defect, including material faults and rust, is replaced free of charge. Damage from handling or accidents is not covered. The year runs from the day the goods leave Sialkot.
If something is wrong with a delivery (a manufacturing defect, or a short or wrong article), tell us on WhatsApp within 7 days of delivery, with a video and photographs of what arrived. Replacement instruments are sent free of charge and dispatched within 24 hours of us seeing them; you pay the shipping, and they reach you as a normal order does.
Damage that happened after the goods left Sialkot is a claim against your carrier. The video of your parcel at the shipping office is sent to you before shipment and is the evidence that claim needs.
