Also called balfour third blade · balfour center blade

A separate blade that fits onto the crossbar of a Balfour-pattern frame at a right angle to its two lateral blades, adding a third direction of retraction rather than lengthening the frame.

A retractor extension is an add-on piece that lengthens a blade or bar of a modular retractor frame when the base component does not reach far enough into a deep wound. It fits onto the end of a standard blade or bar and is locked in place with a screw or pin, adding length to that one component without changing the rest of the assembled frame.

How it is built

  • Straight bar- or blade-shaped extension piece in stainless steel
  • One end machined to mate with and lock onto the base component's shank or bar end (screw, pin, or dovetail fitting)
  • Opposite end left plain, or shaped as a blade tip, depending on the extension type
  • Supplied in a small range of added lengths
  • No hinge or joint of its own, a rigid lengthening piece
  • Frame-specific fitting, matched to the blade or bar it extends

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.

The five grades, side by side, and what each one is for

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.
