BJ4104 Cranial Drill (System 4000)
Precision-engineered cordless cranial drill system with ergonomic design, autoclavable construction, and integrated safety features. Low-noise motor delivers consistent performance with automatic stop-on-breakthrough to protect neural tissue during neurosurgical procedures.
Clinical overview
The BJ4104 is a purpose-designed cordless cranial drill system engineered for precision neurosurgical applications. Its ergonomic handpiece design ensures comfortable handling during extended procedures, while the integrated automatic stop-on-breakthrough mechanism prevents inadvertent penetration into neural tissue—a critical safety feature in intracranial work. The system combines low-noise operation (≤40 dB) with consistent torque delivery, reducing surgeon fatigue and improving procedural control.
Full autoclavability at 155°C (improved specification) enables rapid turnaround sterilisation without compromising component integrity. The environment-friendly nickel-metal hydride battery system provides reliable cordless operation, eliminating tether constraints and improving surgical access. With a 2-year handpiece warranty and comprehensive support, the BJ4104 represents a cost-effective solution for cranial surgery departments requiring dependable, reusable instrumentation.
