Bojin System 4200 Surgical Power Tool Series — Stainless-Steel Quick-Attachment System

System 4200 Surgical Power Tool Series — Stainless-Steel 155°C Quick-Attachment System

The Bojin System 4200 is a stainless-steel modular orthopedic power tool system centered on the BJ4200 multi-function handpiece with quick-attach couplings. The handpiece, attachments, and main components are made of high-strength stainless steel and withstand 155°C autoclave sterilization. The System 4200 shares the BJ4001 battery platform with the System 4000 and is ideal for hospitals that want a modular attachment-based workflow with the durability and sterilization headroom of stainless-steel construction.

Key Advantages of the System 4200 Series

• Ergonomic multi-function handpiece (BJ4200) with new Germany-imported motor for strong, stable output.
• High-strength stainless-steel main components for durability and infection control.
• 155°C autoclavable — exceeds the 134°C / 18-min prion-deactivation standard.
• Quick-attach coupling supports 10+ orthopedic, cranial, and trauma attachments.
• High proper alignment and low noise for long surgical procedures.

Models in the System 4200 Series — Specific Advantages and Differences

Advantage: Stainless-steel multi-function handpiece with Germany-imported motor and quick-attach coupling for the entire System 4200 attachment library.
Difference vs BJ2100 (System 2000): BJ4200 uses the BJ4001 battery and 155°C sterilization; BJ2100 is the 135°C economy modular system.

Advantage: Oscillating saw attachment for joint arthroplasty.
Difference vs BJ4207B: Sagittal saw vs acetabulum reaming drill — BJ4201 shapes bone, BJ4207B prepares the hip socket.

Advantage: Standard bone-drill attachment for K-wire and screw-hole preparation.
Difference vs BJ4202SAO: Standard drill chuck vs AO quick-coupling chuck — BJ4202 for general drilling, BJ4202SAO for AO trauma systems.

Advantage: AO/ASIF-compatible Jacobs chuck for trauma drill bits, taps, and screwdriver shafts.
Difference vs BJ4202: AO quick-coupling chuck for locking plate and intramedullary nail systems.

Advantage: Cannulated chuck for guide-wire-driven drilling. B variant adds reaming; D variant adds oscillating mode for reaming and tapping.
Difference vs BJ4202: Cannulated design accepts K-wires for minimally invasive fracture fixation.

Advantage: Reaming attachment for acetabular cup preparation in total hip arthroplasty. B variant for standard reaming, D variant for deep / specialized reaming.
Difference vs BJ4201: Reaming vs saw — BJ4207 family prepares the hip socket, BJ4201 shapes bone around the joint.

Advantage: Dedicated K-wire drill attachment for K-wire and Steinman pin insertion in trauma surgery. B variant covers a wider pin diameter range.
Difference vs BJ4203B / BJ4203D: K-wire-optimized chuck vs general cannulated drill chuck — BJ4213 for rapid K-wire insertion.

Frequently Asked Questions

Q: What is the difference between the System 4200 and the System 2000?
A: Both are modular quick-attach systems. The System 4200 uses high-strength stainless steel and 155°C sterilization; the System 2000 uses the standard 135°C platform. Choose the System 4200 when maximum sterilization headroom and stainless-steel durability are required.

Q: Can the BJ4213A and BJ4213B K-wire attachments share the same handpiece?
A: Yes. Both attach to the BJ4200 handpiece via the same quick-attach coupling. BJ4213A is for small-diameter K-wires, BJ4213B for a wider range.
