Bojin SYSTEM 2000 Orthopedic Power Tool BJ2107 Acetabulum Drill Attachment-Multifunctional
The BOJIN SYSTEM 2000 BJ2107 Acetabulum Reamer Attachment is designed for controlled low-speed, high-torque reaming in hip and orthopedic procedures, providing up to 10 N·m of torque with a 0-270 rpm operating range and compatible coupling options for selected surgical configurations, while the quick cup-link connection and rotating interface make attachment positioning easier during acetabular preparation.

Acetabular Reaming Within a Modular Power System
The BJ2107 is an acetabulum reamer attachment for the BOJIN SYSTEM 2000 multifunctional orthopedic power-tool platform. It provides a dedicated reaming function for procedures where controlled enlargement or preparation of the acetabular area is required.
Because the BJ2107 works as an attachment, the same main handpiece can be used with other compatible surgical heads for drilling, sawing, cranial work, fixation and related procedures. This allows hospitals to configure the system according to the cases they handle rather than purchasing a separate complete power unit for every function.
Low-Speed Rotation With High Available Torque
The BJ2107 operates at 0-270 rpm and provides maximum torque of up to 10 N·m. This gives the attachment a low-speed, high-torque working profile that is well suited to reaming tasks where steady rotational force is more important than rapid movement.
The operator can work within the stated speed range according to the procedure, accessory and surgical technique. The high torque specification also gives the attachment a different role from the higher-speed drilling and bur options available within the SYSTEM 2000 range.
Designed for Acetabular Preparation
The main purpose of the BJ2107 is acetabular reaming. A dedicated reaming head can make it easier for the surgical team to prepare the appropriate equipment when the procedure requires this specific function.
The attachment is intended for orthopedic applications involving acetabular preparation and related reaming work. Actual clinical use should follow the manufacturer's intended purpose and the applicable surgical technique.

A Different Tool From Standard Bone Drills
Although drilling and reaming both use rotary motion, the two functions are not interchangeable. The BJ2107 is specifically configured for acetabular reaming and operates at a lower speed with higher available torque than several other drilling attachments in the SYSTEM 2000 range.
This distinction is useful when selecting equipment for different stages of an orthopedic procedure.
Stryker and Large AO Coupling Options
The BJ2107 is listed with Stryker coupling and Large AO coupling configurations. These options allow customers to select the interface that corresponds with their intended equipment setup.
For hospitals already using a particular coupling standard, choosing the matching version can make integration easier. Exact compatibility should be confirmed with BOJIN before ordering and clinical use.
Quick Cup-Link Attachment Connection
The SYSTEM 2000 uses a quick cup-link mechanism for interchangeable attachments. The BJ2107 can therefore be fitted to the compatible handpiece without requiring a completely separate motor system.
This attachment-based design can make the workflow more convenient when different surgical functions are required from the same core platform.
