Built to the scale of the ear canal and mastoid field - jaw depth and width measured in single-digit millimetres - with hooked prongs, rather than the centimetre-scale blades of the general-surgery patterns.
A self-retaining retractor is a surgical retractor built to hold a wound or cavity open on its own, without an assistant's hand, once it is set. Two opposing arms are joined at a box-lock or single-pivot hinge (the same joint action as a pair of scissors), and a ratchet bar locks the arms at the spread the operator chooses. It is distinguished from a hand-held retractor of the same blade or prong shape only by this added locking joint.
Minimum order 300 instruments The minimum for surgical instruments. Mixed orders are quoted against your list.
Lead time Instruments ~2-3 weeks · full sets ~4-6 weeks after advance.
Quality control

How it is built
- box-lock or single-pivot hinge with a scissor-style opening action
- ratchet bar (some patterns use a screw or catch) locks the arms open at the chosen spread
- working end is either a set of curved prongs, commonly 2, 3 or 4 per side, or flat/serrated blades, sharp or blunt tipped
- on some patterns the blades are interchangeable and clip onto a common ratchet frame rather than being fixed
- one-piece forged stainless steel arms, straight or slightly curved
- available in named patterns of differing prong count, blade width and overall length

This describes the self-retaining retractor as an article. 43 other articles in this catalogue 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 sterilisation 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.
Customised 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.
