Intended Use

The evoDrill Cranial Perforators are single-use surgical devices for cranium perforation. The perforators with the 3mm step automatically release and stop perforating at cranial bone thickness of at least 3mm. The perforators with the 1mm step automatically release and stop perforating at cranial bone thickness of at least 1mm.

Device Story

Single-use surgical cranial perforator; used for trephining cranial bone. Driven by pneumatic or electric surgical motor (800-1500 RPM). Features automatic spring-loaded release mechanism; inner drill coupled to housing via axial force; resistance from bone maintains coupling; upon piercing, resistance drops below spring force, causing automatic decoupling and stopping of perforation. Used in clinical/surgical settings by surgeons. Benefits patient by preventing over-penetration of skull bone.

Clinical Evidence

Bench testing only. Evaluated automatic stop mechanism, drilling time, and device geometry. Biocompatibility testing performed per ISO 10993. Sterilization validation performed per ISO 11137 and ISO 11607. All testing met acceptance criteria.

Technological Characteristics

Materials: Plastic, stainless steel, aluminum. Principle: Mechanical spring-loaded automatic decoupling. Energy: Pneumatic or electric motor (800-1500 RPM). Form factor: Single-use drill with Hudson fitting. Sterilization: Radiation (SAL 10^-6).

Indications for Use

Indicated for cranium perforation in patients requiring burr holes. Available in variants for cranial bone thickness of at least 1mm or at least 3mm.

Regulatory Classification

Identification

Powered compound cranial drills, burrs, trephines, and their accessories are bone cutting and drilling instruments used on a patient's skull. The instruments employ a clutch mechanism to disengage the tip of the instrument after penetrating the skull to prevent plunging of the tip into the brain.

The evonos evoDrill cranial perforator are devices similar in design and construction to other cranial perforators currently on the market; (e.g.: Acra Cut Automatic Cranial Drill DGR-1 #200-241; DGR-II #200-251 and Codman Disposable Perforators 26-1222, 26-1223). The evonos evoDrill cranial perforator requires a motor and an attached or integrated speed reducer in order to run the perforators at a speed range of 800 RPM to 1500 RPM. Image /page/6/Picture/2 description: The image shows a medical drill being used on a bone. The drill is labeled "evoDrill Made in Germany 14-11-1". The drill is silver with a blue handle. The bone is tan and brown. Picture 1: Schematic illustration of the bone perforation ### INDICATIONS FOR USE The evoDrill Cranial Perforators are single-use surgical devices for cranium perforation. The perforators with the 3mm step automatically release and stop perforating at cranial bone thickness of at least 3mm. The perforators with the 1mm step automatically release and stop perforating at cranial bone thickness of at least 1mm. | Device | evoDrill | Codman Cranial Perforator | AcraCut Cranial Perforator | |------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Manufacturer | evonos GmbH & Co.
