The BJ5505 Cranial Bur is a battery-powered surgical handpiece designed for professional neurosurgical and cranial surgery applications. It is intended for procedures that require controlled drilling, milling and removal of cranial bone, providing a specialized solution for surgical teams working in delicate anatomical areas.
Its high-speed operating capability is designed to support efficient material removal while allowing the operator to maintain control over the instrument. The attachment can be used with the supplied milling accessory according to the requirements of the surgical procedure and the applicable clinical technique.
The BJ5505 provides an output power of up to 200 W and a rotational speed range of 0-23,000 rpm. The broad speed range gives users flexibility when performing different cranial drilling or milling tasks.
High rotational speed can help support efficient bone processing, while adjustable operation allows the surgical team to select an appropriate working speed for the specific procedure. Controlled instrument response is particularly important when operating near sensitive anatomical structures.
Neurosurgical instruments require precise manipulation and a high degree of operator control. The BJ5505 incorporates an ergonomic configuration designed to provide a practical grip and facilitate positioning during delicate procedures.
Its compact battery-powered arrangement also avoids the restrictions associated with a direct power cable, helping provide greater freedom of movement around the operating field. This can be useful when the surgical team needs to reposition the instrument repeatedly during a procedure.
The BJ5505 has a specified operating noise level of no more than 40 dB. A low-noise instrument can contribute to a more comfortable working environment, particularly in procedures where concentration and communication are important.
The reduced noise specification complements the high-speed operating capability, providing a balance between efficient drilling performance and a more controlled operating-room experience.
The handpiece operates at 9.6 V and uses an 1800 mA battery configuration. Two batteries are included in the standard package, giving medical teams an additional power source for equipment preparation and rotation.
Battery operation can simplify instrument positioning by eliminating the need to manage a power cable around the surgical field. It also provides greater flexibility when configuring equipment for different operating-room environments.
