A double-ended body bent into a Z-shaped double angle, with a different blade depth at each end, keeping the handle clear of the wound, unlike the single-ended Blount and Smillie patterns in this family.
A knee retractor is a handheld lever-type retractor sized and curved for exposure of the knee joint, larger than the general-purpose Hohmann-type retractors used elsewhere in orthopedic surgery. It has a single flat or gently curved blade at the working end, shaped to follow the contour of the femoral or tibial condyle, joined at a fixed angle to a flat or round steel handle. It carries no ratchet, spring or catch: it is a plain lever, not a self-retaining retractor, and stays positioned only while held or wedged against bone. Blades are supplied in more than one width and curvature, and matched left/right offset-handle pairs exist for use on either side of the joint.

This describes the knee retractor 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.

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.
