Bojin SYSTEM 2000 Orthopedic Power Tool BJ2109 Reciprocating Saw Attachment-Multifunctional
The BJ2109 reciprocating saw attachment adds a dedicated oscillating cutting function to the BOJIN SYSTEM 2000 platform, with a working range of up to 15,000 oscillations per minute and a quick cup-link connection that can be rotated through 360°, giving surgeons more freedom when setting the blade position for bone sectioning, trimming and other orthopedic cutting tasks.

Reciprocating Cutting as Part of a Modular System
The BJ2109 is a dedicated reciprocating saw attachment for the BOJIN SYSTEM 2000 orthopedic power-tool platform. Its purpose is straightforward: provide a back-and-forth cutting function while allowing the same main handpiece to be used with other compatible attachments.
This arrangement gives hospitals the option to build one system around the procedures they perform most often. A saw attachment can be selected when bone cutting is required, while a drill, reamer or driver can be fitted for another surgical task.
Up to 15,000 Oscillations per Minute
The BJ2109 is specified for an oscillation range of 0-15,000 oscillations per minute. The high-frequency movement is intended to provide the blade action required for powered orthopedic cutting.
The final cutting result depends on the blade, the material being cut and the surgical technique. The stated speed range provides a clear reference when comparing the BJ2109 with other cutting attachments in the same product family.
A Purpose-Built Cutting Attachment
Unlike a multifunctional handpiece that combines several mechanisms in one body, the BJ2109 focuses on reciprocating sawing. This makes it easier to identify and prepare when a procedure specifically calls for a reciprocating blade.
For departments that already use the SYSTEM 2000 handpiece, adding the BJ2109 can extend the available functions without requiring another complete motor unit.

Quick Cup-Link Connection
The SYSTEM 2000 uses a quick cup-link mechanism for its interchangeable attachments. The BJ2109 can therefore be connected to the compatible handpiece as part of the modular setup.
A quick connection can make equipment preparation less complicated when different attachments are used across different procedures. The exact connection should be checked against the intended handpiece and configuration before use.
360° Rotating Position
The attachment interface supports 360° rotation, allowing the saw to be positioned according to the preferred approach. This gives the operator more flexibility when establishing the blade orientation before starting a cut.
The ability to adjust the working direction can be useful when access to the surgical site changes during positioning or when the cutting line requires a particular instrument angle.
Designed for Bone Sectioning and Trimming
The BJ2109 is intended for orthopedic cutting applications in which a reciprocating blade is preferred. Depending on the procedure and compatible blade, the saw can be used for bone sectioning, trimming and related preparation work.
Its role is different from rotary drilling and reaming attachments, which use continuous rotation rather than the back-and-forth movement of a reciprocating saw.
