System includes twist drill bits (16-30 cm length, 2.4-3.2 mm diameter), drill stops, drill stop wrenches, drill sleeve guides, and guide blocks. Used intraoperatively by surgeons; drill sleeve guides and guide blocks interface with stereotactic frames to minimize bit wobble and ensure precise placement. Device provides mechanical access; does not involve electronic processing or AI. Benefits include precise, controlled skull penetration for neurosurgical access. ## Clinical Evidence Bench testing only. Evaluations confirmed drilling efficiency (drilling through simulated skull in < 1 minute), drill bit run-out (wobble) performance with and without guide accessories, and mechanical compatibility with stereotactic frames. All tests passed. ## Technological Characteristics Materials: Stainless steel. Principle: Mechanical drilling. Dimensions: 16-30 cm length, 2.4-3.2 mm diameter. Connectivity: None (mechanical). Sterilization: Ethylene Oxide (for sterile-supplied components). Components: Drill bits, drill stops, wrenches, sleeve guides, guide blocks. ## Regulatory Identification Powered simple cranial drills, burrs, trephines, and their accessories are bone cutting and drilling instruments used on a patient's skull. The instruments are used with a power source but do not have a clutch mechanism to disengage the tip after penetrating the skull. ## Predicate Devices - Twist Drills ([K062842](/device/K062842.md)) - MRI Cranial Drill ([K122456](/device/K122456.md)) - MRII Cranial Drill and Accessories ([K160129](/device/K160129.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

K160129 MRII Cranial Drill and Accessories | #### 5.1 Product Description The device under review is a family of cranial drill bits and accessories. These cranial drill bits and accessories are applied to create a hole through the skull in support of neurological procedures. Cranial drill bits are twist drill bits used for drilling holes in the skull, supporting access to the brain for brain biopsy, brain contacting electrode placement, electrode accessory placement such as Anchor Bolts or other needs as determined by the user. The cranial drill bit variations are 16 cm to 30 cm length and 2.4 mm to 3.2 mm outer diameter. Accessories to the cranial drill bits include: - Drill Stop: A collar placed on the outer diameter of the drill bit to provide a depth placement ● indicator. - Drill Stop Wrench: The Drill Stop Wrench attaches the Drill Stop to the cranial drill bit. - . Drill Sleeve Guide: The Drill Sleeve Guide is an optional accessory, consisting of a hollow tube of stainless steel that the cranial drill bit passes through to minimize the wobble of the drill bit as it is passed to the skull. The Drill Sleeve Guide is placed within a stereotactic frame. - . Guide Block: A Guide Block is an optional accessory that adapts to a stereotactic frame to hold the Drill Sleeve Guide. {4}------------------------------------------------ #### 5.2 Indications for Use The Cranial Drill Bits and accessories are intended to be used for drilling holes in the skull for neurological procedures, such as brain biopsy, brain contacting electrode and electrode accessory device placement. #### 5.3 Summary of Technological Characteristics The following table provides a side-by-side comparison the Cranial Drill Bits and accessories to the predicate devices applied to support this pre-market notification. | Table 5.3-1: Substantial Equivalence Technical Characteristics | | | | | |----------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------| | Feature | Cranial Drill Bits and
