Small ophthalmic pattern, sized to catch and lift an eye muscle rather than a limb tendon.
A tenotomy hook is a single-piece, hand-held hook: there is no joint, hinge or lock anywhere on the instrument. One end is a thin, curved or angled hook, blunt on most patterns and finely serrated on the inside curve on at least one named pattern; the other end is a plain or knurled round handle. The hook is small, typically 5-6mm from tip to shank, noticeably shorter and finer than a general blunt or nerve hook.

How it is built
- Single-piece, hand-held instrument: no joint, hinge, lock or ratchet
- Working end is a thin, curved or angled hook, small enough to slip under a slender tendon or muscle edge
- Hook is blunt on most named patterns; at least one pattern (O'Connor) has fine serrations on the inside of the hook
- Opposite end is a plain or knurled round handle
- At least one named pattern (Hardesty) carries one or two fine depth markings etched onto the shank a set distance back from the hook tip

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.

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.
