System 2000 Surgical Power Tool Series — Modular 360° Quick-Attachment Orthopedic System
The Bojin System 2000 is a modular orthopedic power tool system centered on the BJ2100 multi-function handpiece that drives a complete library of quick-change attachments. The 360° rotating, easy-assemble / disassemble design lets surgeons switch between sagittal saw, bone drill, AO drill, cannulate drill, cranial drill, cranial bur, sternum saw, acetabulum reamer, reciprocating saw, and torque-limiter attachments in seconds. Main components are made of high-strength stainless steel and the handpiece is rated for 135°C autoclave sterilization.
Key Advantages of the System 2000 Series
- Single handpiece (BJ2100) drives 17+ orthopedic attachments, reducing capital cost and OR storage.
- 360° rotating quick-attach coupling allows optimal hand positioning for every surgical approach.
- High-strength stainless-steel main components for durability and infection control.
- 135°C autoclavable handpiece and attachments.
- Includes dedicated torque-limiter (BJ2110 / BJ2111) and TPLO (BJ2112) attachments for veterinary and specialty orthopedics.
Models in the System 2000 Series — Specific Advantages and Differences
BJ2100 Multi-Function HandpieceAdvantage: Single high-torque handpiece with 360° rotating quick-attach coupling for the entire System 2000 attachment library.
Difference vs BJ4200 (System 4200): BJ2100 uses the standard BJ1001 battery and 135°C sterilization; BJ4200 is the 155°C stainless-steel flagship.
Advantage: Oscillating saw attachment for joint arthroplasty. BJ2101S is the short-shaft variant for confined surgical fields.
Difference vs BJ2109: Sagittal oscillating stroke vs reciprocating linear stroke — BJ2101/BJ2101S for shaping, BJ2109 for rapid resection.
Advantage: Standard bone-drill attachment for K-wire and screw-hole preparation.
Difference vs BJ2103: Solid drill chuck vs cannulated drill chuck — BJ2102 for standard drilling, BJ2103 for guide-wire-driven fixation.
Advantage: AO/ASIF-compatible Jacobs chuck for trauma drill bits, taps, and screwdriver shafts.
Difference vs BJ2102: AO quick-coupling chuck instead of a keyless drill chuck — ideal for AO locking plate systems.
Advantage: Cannulated chuck for guide-wire-driven drilling; B variant adds reaming, D variant adds oscillating mode for reaming and tapping.
Difference vs BJ2102: Cannulated design accepts K-wires; B/D variants add dual-function modes.
Advantage: Low-speed, high-torque drilling for burr holes and craniotomies.
Difference vs BJ2105: Twist-drill (axial) vs bur (side-cutting) — BJ2104 for perforation, BJ2105 for shaping.
Advantage: Diamond and carbide bur for cranioplasty, skull base, and tumor resection.
Difference vs BJ2104: Bur vs drill action for fine bone shaping.
Advantage: Reciprocating sternum saw with safety guard for median sternotomy.
Difference vs BJ2109: Sternum-specific blade and guard vs general-purpose reciprocating saw.
Advantage: Reaming attachment for acetabular cup preparation. B variant is dual-function with reverse, D variant for deep reaming.
Difference vs BJ2101: Reaming vs oscillating saw — BJ2107 family prepares the hip socket, BJ2101 shapes bone around the joint.
Advantage: Linear back-and-forth stroke for rapid bone resection.
Difference vs BJ2101: Reciprocating vs oscillating stroke — BJ2109 for long cuts, BJ2101 for shaping.
Advantage: Calibrated torque-limit attachments (1.5 Nm and 4 Nm) for controlled locking-screw and intramedullary-nail locking.
Difference vs BJ2102SAO: Torque-limiting vs free-running AO chuck — BJ2110/BJ2111 prevent over-tightening in locking hardware.
Advantage: Dedicated Tibial Plateau Leveling Osteotomy (TPLO) saw attachment for veterinary orthopedic procedures.
Difference vs BJ2101: TPLO-specific radial blade vs general oscillating blade — BJ2112 for veterinary cruciate ligament surgery.

Frequently Asked Questions
Q: Can I add a new attachment to my existing System 2000 handpiece?
A: Yes. Any System 2000 attachment (BJ2101 through BJ2112) docks onto the BJ2100 handpiece with the same quick-attach coupling.
Q: What is the difference between BJ2103B and BJ2103D?
A: BJ2103B adds a reaming function (dual forward / reverse). BJ2103D adds an oscillating mode suitable for difficult fracture patterns and intramedullary reaming.
