BJ4104 Cranial Drill (System 4000)
Precision-engineered cordless cranial drill system with 110W output power, variable speed control (0–1100 rpm), and ultra-low noise operation. Fully autoclavable handpiece with imported motor technology, designed for safe cranial bone perforation with automatic stop-through protection to prevent neural tissue damage.
Clinical Overview
The BJ4104 is a purpose-designed cranial drill system engineered for precision bone perforation in neurosurgical applications. The handpiece features an ergonomic design optimised for extended surgical procedures, with a fully autoclavable construction (155°C) enabling reliable sterilisation between cases. The imported motor delivers consistent torque output (3.3 Nm) across the entire speed range, ensuring predictable cutting performance and reduced vibration during critical bone work.
A key clinical advantage is the automatic stop-through mechanism, which halts spindle rotation immediately upon breakthrough, preventing inadvertent neural tissue trauma. The system operates at ≤40 dB, minimising acoustic stress in the operating theatre. Powered by environment-friendly nickel-metal hydride battery technology with rapid charging capability, the BJ4104 supports efficient surgical workflow without compromising sterility or performance.
