Short answer
A brain spatula is a hand-held, non-powered neurosurgical instrument with a flat, blunt blade, used to manipulate neural tissue during brain surgery. In U.S. regulation, spatulas are named as examples of non-powered neurosurgical instruments under 21 CFR 882.4535, a Class I category exempt from 510(k) premarket notification subject to 21 CFR 882.9.
Definition and scope
NLM’s AccessGUDID describes a brain spatula as a hand-held, non-powered instrument for manipulating neural tissue during brain surgery, with a flat, blunt blade that is typically high-grade stainless steel. The Global Medical Device Nomenclature (GMDN) carries it as the term “Brain spatula” (code 35343), and the FDA product code on the example record below is HAO, “Instrument, Surgical, Non-Powered”.
The regulation behind that category, 21 CFR 882.4535, defines a non-powered neurosurgical instrument as a hand instrument or accessory used during neurosurgical procedures to cut, hold, or manipulate tissue, and lists spatulas among its examples (eCFR, checked 2026-10-31). For the wider family of neurosurgical hand instruments, see neurosurgical instruments.
How the instrument is described in practice
The patent literature gives the clearest account of the role. In the background of US11653908B2 (Brain Innovations LLC, granted 2023-05-23), the surgeon must push brain tissue aside to reach the target, and spatulas create clearance. The patent notes that spatulas are held by arms attached to the clamp that stabilizes the head, or in some cases to the surgical table, and that a long arm makes stability hard to obtain and may obstruct the surgeon’s movement. This describes the problem the patent addresses, not instructions for using an instrument.
That background points to two separate supply items. The blade itself is a hand instrument. A fixed-arm arrangement adds mounting hardware, which is a different product and is not covered by the blade’s listing.
Where it sits among related FDA categories
Three FDA regulations are easy to confuse because all concern holding or moving tissue. The category belongs to the regulation the device is listed under, not to the shape of the blade.
| Regulation | What it covers | Class |
|---|---|---|
| 21 CFR 882.4535 | Non-powered neurosurgical instrument: hand instrument or accessory used to cut, hold, or manipulate tissue; spatulas are named as examples | Class I, exempt from 510(k) subject to 882.9 |
| 21 CFR 882.4800 | Self-retaining retractor for neurosurgery: a self-locking device used to hold the edges of a wound open during neurosurgery | Class II (performance standards) |
| 21 CFR 878.4800 | Manual surgical instrument for general use, including the general retractor (FDA product code GAD) | Class I, exempt from 510(k) subject to 878.9 |

Reading a brain spatula listing: a checklist
The AccessGUDID record for the V. Mueller Neuro/Spine TAKA Super Flexible Brain Spatulas (model S-0817, CareFusion 2200, Inc.; DI 10885403110771; checked 2026-10-31) shows which fields a listing exposes. Each row below is taken from that record.
| Field | What the example record says |
|---|---|
| Description | Ebonized, malleable, super flexible brain spatulas |
| Tip size | 7.0 mm tip |
| Overall length | 9 in (23 cm) |
| GMDN term | Brain spatula, code 35343 |
| FDA product code | HAO, Instrument, Surgical, Non-Powered |
| Single-use | No, reusable |
| Supplied sterile | No; requires sterilization before use (steam / moist heat) |
The record does not list a device class, so the class has to be taken from the regulation, not from the listing. The not-sterile and reusable flags mean the facility needs a reprocessing route for the instrument; see autoclavable vs single-use surgical instruments for how that trade-off is framed.
Where it matters for labs, clinics and supply decisions
- Match the regulation, not the name. A spatula and a self-retaining retractor sit in different FDA classes (I and II), so a request that mixes the terms can point at the wrong category.
- Read the sterility flags. The example record is not supplied sterile and is reusable, so it is a reprocessing item rather than a ready-to-open item.
- Keep mounting hardware separate. Where a spatula is held by fixed arms, the arms are a separate item from the blade.
- Record the dimensions. Tip size and overall length are the two size fields the example record carries.
Common misunderstandings
“A brain spatula is the same as a brain retractor.”
The terms overlap in everyday speech, but the FDA text separates the hand instrument (882.4535) from the self-locking retractor (882.4800). A hand-held spatula is not a self-retaining device by that definition.
“Every neurosurgical instrument is Class II.”
The non-powered hand-instrument category is Class I and exempt from 510(k) subject to 882.9; Class II applies to the self-retaining retractor in 882.4800.
“The listing tells you the class.”
The example AccessGUDID record gives a product code and nomenclature term but no class.
FAQ
What is a brain spatula?
A hand-held, non-powered instrument with a flat, blunt blade for manipulating neural tissue during brain surgery, typically made of high-grade stainless steel (AccessGUDID, checked 2026-10-31).
Is a brain spatula the same as a brain retractor?
Not in FDA terms. Spatulas are named under 21 CFR 882.4535; self-retaining neurosurgical retractors are defined separately in 21 CFR 882.4800.
What FDA class is a brain spatula?
The non-powered neurosurgical instrument category in 21 CFR 882.4535 is Class I, exempt from 510(k) subject to 882.9.
Is a brain spatula supplied sterile?
The example record (model S-0817) is not supplied sterile, is reusable, and requires steam sterilization before use. Other products may differ, so each product’s instructions for use apply.
