Powerful but precise bite
Precisely engineered components provide predictable cutting without a rough feel in a deep field.
K-Rex™ is a reusable Kerrison-type rongeur for precise, controlled bone removal in neurosurgery, spine surgery, orthopaedics and trauma. The Fairgrip™ ultra handle reduces hand fatigue, while smart decoupling simplifies post-operative cleaning.
K-Rex should be considered where a standard bone rongeur feels too coarse: decompression, neuro and spine surgery, orthopaedics, trauma and complex bone removal near delicate structures.
The value for the team is simple: the surgeon gets a precise, controlled bite, and CSSD gets a rongeur that opens quickly for cleaning, inspection and lubrication after surgery.
Short points for the surgeon, scrub nurse and procurement.
Precisely engineered components provide predictable cutting without a rough feel in a deep field.
Tip geometry helps the surgeon work more precisely and reduce the risk of unnecessary damage to delicate structures.
Dimple knurling improves control, feel and grip stability during long spine/neuro procedures.
The front handle slides forward: the instrument opens for cleaning and lubrication without losing components.
Standard for dense structures. Thin for delicate tissue and complex anatomy.
180, 200, 230, 280 mm and a 40° upward angle help match the access to the required depth and maneuver.
In a Kerrison punch, the critical zone is the sliding mechanism and internal channel. This is where biological soil can remain after use if the instrument does not open.
K-Rex moves into cleaning position with one simple motion: the front handle is pushed forward, opening access for rinsing, visual inspection, drying and lubrication.
180, 200, 230 and 280 mm for different field depths: from limited access to deeper anatomical structures.
Standard Footplate for dense structures. Thin Footplate for delicate tissue and more precise work in complex anatomy.
The angle adds reach, maneuverability and control when working in an awkward or deep field.
K-Rex received the Red Dot Design Award 2023, strengthening the design and ergonomics argument.
The official name, intended use and available instrument configurations.
The official product name is GEISTER K-Rex™ Rongeur. Searchers may also type K Rex, Ki Rex, Kirex or Ronjer, but this page describes the original GEISTER K-Rex Kerrison bone punch.
It is a reusable Kerrison-type bone punch for controlled bone removal in neurosurgical, spinal, orthopaedic and trauma procedures.
GEISTER offers 180, 200, 230 and 280 mm lengths, a 40° upward angle and Standard or Thin Footplate options. TLM selects the configuration for the approach and procedure and prepares a commercial offer for Ukraine.
