Intended Use

The Symmetry Sharp Kerrison® Rongeur is indicated for cutting bony tissue of the spine. The Symmetry Sharp Kerrison® Rongeur is a manually operated instrument that consists of a Handle and Tips (available in single use or reusable).

Device Story

Manual surgical instrument; used for cutting bony tissue in spine. Consists of handle and detachable tips (single-use or reusable). Surgeon operates device by squeezing handle; mechanical compression closes cup-and-ball assembly; sliding shaft and stationary footplate cut bone. Tips available in 1-4mm sizes; handles in 5-7 inch lengths. Reusable components require cleaning and steam sterilization; single-use tips provided sterile via gamma sterilization. Device provides surgeon with various cutting configurations for spinal bone characteristics. Benefits include precise bone removal during spinal procedures.

Clinical Evidence

Bench testing only. No clinical data. Performance testing included cleaning validation (residual protein/hemoglobin/carbohydrate), steam sterilization validation (SAL 10^-6), gamma sterilization validation (SAL 10^-6), durability testing (100 cuts for tips, 50 cycles for handles), corrosion resistance, and shelf-life studies (2 years) per ASTM standards.

Technological Characteristics

Manual rongeur; 420 stainless steel construction; German Stainless Steel 1.4301/1.4310 (equivalent to 304/303/301 SS) for mating components. Mechanical actuation via cup-and-ball assembly. Dimensions: 1-4mm cup sizes, 5-7 inch handle lengths. Sterilization: Steam (reusable components), Gamma (single-use tips). No software or electronics.

Indications for Use

Indicated for cutting bony tissue of the spine in patients requiring spinal surgery.

Regulatory Classification

Identification

A manual rongeur is a manually operated instrument used for cutting or biting bone during surgery involving the skull or spinal column.

| Predicate<br>Device | K130541 Kerrison Disposable Tip Rongeur |
| Intended Use | The Symmetry Sharp Kerrison® Rongeur is indicated for cutting<br>bony tissue of the spine. The Symmetry Sharp Kerrison®<br>Rongeur is a manually operated instrument that consists of a<br>Handle and Tips (available in single use or reusable). |
| Device<br>Description | The Symmetry Sharp Kerrison Rongeur is designed to have<br>detachable tips that are disposable. The detachable tips are<br>provided as either sterile single use or as nonsterile reusable tips.<br>The reusable tips must be cleaned and sterilized before use. The<br>sterile, disposable tips are available in 4 cup sizes: (1, 2, 3, and 4<br>mm); which are identifiable by etchings on each device. The<br>Reusable Tips for the Symmetry Sharp Kerrison® Rongeur Handle<br>are available in 3 cup sizes: (2, 3, and 4 mm); which are<br>identifiable by etchings on each device. The reusable tips have a<br>mating code etched on each pair to ensure that only matched pairs<br>are used. Each tip is designed with a shaft key that fits into its<br>mating slot on the detachable instrument handle. The tip has cups,<br>one within the stationary footplate and the other within the upper<br>sliding shaft, performing the cutting of the bony tissue in the spine<br>area. The various cup sizes within the working tips provide the<br>surgeon various cutting configurations needed for the different<br>characteristics of the bony tissue within the spine. The Symmetry<br>Sharp Kerrison® Rongeur Handle operates with a cup and ball<br>assembly for smooth motion of the footplate when the handle is<br>squeezed. The detachable, reusable instrument handles of this<br>device are provided non-sterile and must be cleaned and sterilized<br>prior to use. The instrument handles are available in three shaft<br>lengths: (5, 6, and 7 inches). |
