Langenbeck Retractor: What It Is, FDA Class and How Listings Are Sized

A Langenbeck retractor is a hand-held surgical retractor. See its FDA classification, product codes and how manufacturers state blade sizes in device records.

Short answer: A Langenbeck retractor is a hand-held surgical retractor, usually described in catalogues by its blade size and overall length. In the United States, retractors of this kind fall under the Class I general-surgery regulation 21 CFR 878.4800 (FDA product code GAD), and dental versions under 21 CFR 872.4565 (product code EIG). This page is general product information, not medical advice and not a procedure guide.

Definition and scope

“Langenbeck retractor” is a catalogue name, not an FDA device type. FDA does not define a “Langenbeck” category; the name appears in manufacturers’ own device descriptions. Under 21 CFR 878.4800(a), a manual surgical instrument for general use is “a nonpowered, hand-held, or hand manipulated device, either reusable or disposable, intended to be used in various general surgical procedures”, and the regulation lists “retractor” among the covered devices. The same paragraph says an instrument with specialized uses in a specific medical specialty is classified in separate regulations in parts 868 through 892.

Under 878.4800(b), the class is Class I (general controls), and the device is exempt from premarket notification (510(k)) procedures, subject to the limitations in 21 CFR 878.9. For background on that pathway see the guide to FDA 510(k) and De Novo submissions.

How the name is used in device records

The clearest public evidence of how manufacturers use the name is FDA’s Global Unique Device Identification Database (GUDID), queried through openFDA. On 2026-10-30, a search of the device description field for “langenbeck” returned 697 records. The record text covers several naming styles, for example “Kocher-Langenbeck Retractor”, “Langenbeck Retractor” with a number, and “Langenbeck-Mannerfelt (modif.) Retractor”.

  • 136 of the 697 records also contain the word “kocher”.
  • 685 of the 697 records are flagged as not single-use; 12 are flagged single-use.
  • Records describe handle styles such as finger ring, Cottle and triangle handles.

Types and related names, as coded in GUDID

The table counts the same 697 records by how FDA product codes and GMDN device terms were assigned by the submitting manufacturers. A record can carry more than one code or term, so the rows do not add up to 697. These are manufacturer-submitted data, and openFDA itself states that results should be treated as unvalidated.

Coding What it is Records
Product code GAD “Retractor”, Class 1, 21 CFR 878.4800, General and Plastic Surgery 350
Product code EIG “Retractor, All Types”, Class 1, 21 CFR 872.4565, Dental 69
Product code GEG “Elevator, Surgical, General and Plastic Surgery”, Class 1, 21 CFR 878.4800; the records include Langenbeck periosteal elevators 88
GMDN term “Hand-held surgical retractor, reusable” Hand-held retractor category 356
GMDN term “Self-retaining surgical retractor, reusable” Self-retaining retractor category 63
GMDN term “Hand-held dental retractor” Dental retractor category 40
GMDN term “Periosteal elevator, reusable” A different instrument type that shares the name 65

The practical reading: the same name is attached to retractors filed as general surgery, retractors filed as dental, and instruments that are not retractors at all, such as the Martin-Langenbeck periosteal elevator.

Reading a Langenbeck listing

Dimensions are the main thing that varies between listings, and manufacturers state them in different formats. Examples taken from GUDID record text on 2026-10-30:

  • Hayden Medical: “Kocher-Langenbeck Retractor 8-1/4″ (21cm), blade 40mm x 12mm”.
  • Marina Medical Instruments: “Langenbeck Retractor 50mm x 11mm, 25cm”.
  • Aesculap: “KOCHER-LANGENBECK Retractor, 8 1/2″, (215 mm), depth: 35 mm, width: 15 mm, non-sterile, reusable”.
  • Ambler Surgical: “Langenbeck retractor, 8 1/4”, 15.0mm x 85.0mm blade, finger ring handle”.

Two points follow from these records. First, overall length is quoted in inches, centimetres or millimetres depending on the maker. Second, the order of the two blade numbers is not standardised across these examples (40 x 12 mm in one, 15 x 85 mm in another), so a listing’s own labels, such as “depth” and “width”, should be read rather than assumed. The sterility and reuse status are separate fields in GUDID; the Aesculap record above states non-sterile and reusable.

Where it matters for labs, clinics and supply records

For anyone maintaining an instrument inventory or a supply catalogue, the regulatory identity is the stable part. A Langenbeck retractor of the general-surgery kind is a Class I device exempt from 510(k) under 878.4800, subject to the limitations in 878.9. Dental retractors are coded separately (EIG, 872.4565, Class 1); that regulation words its 510(k) exemption differently, conditioned on materials used before May 28, 1976 and subject to the limitations in 21 CFR 872.9, so it should be read directly rather than assumed to match 878.4800. The product code, the regulation number and the manufacturer’s own description are what identify the item, not the name alone. Related background is in the CASRAI guides to surgical retractors and orthopedic surgical instruments, and in the dictionary entry for the Medical Device Amendments of 1976.

Common misunderstandings

  • “Langenbeck” is one fixed design. The records show different blade sizes, lengths and handle styles under the same name.
  • It is always a general-surgery device. Dental versions are coded under EIG and 21 CFR 872.4565.
  • Every record with the name is a retractor. Periosteal elevators and a nerve dissector also carry the name in GUDID.
  • Class I means no rules apply. Class I means general controls apply, and the 510(k) exemption under 878.4800 is subject to limitations in 21 CFR 878.9.
  • It is always reusable. Most records are flagged not single-use, but 12 of 697 are flagged single-use.

FAQ

What FDA class is a Langenbeck retractor?

Retractors of the general-surgery kind are Class I (general controls) under 21 CFR 878.4800, product code GAD. Dental retractors are filed under product code EIG and 21 CFR 872.4565, also Class I.

Is “Langenbeck” an FDA device category?

No. It is a name used in manufacturers’ own device descriptions in GUDID, which returned 697 records for the term on 2026-10-30.

Is every Langenbeck record a retractor?

No. The records also include periosteal elevators (such as the Martin-Langenbeck) and a nerve dissector.

Are Langenbeck retractors reusable?

Of the 697 records, 685 are flagged not single-use and 12 are flagged single-use, so the record for the specific item should be checked.
