Components: Femur: adjustable aiming rod, lateral bracket Tibia: adjustable aiming rod, cross nail, lateral bracket

Material: PEEK5600CF30 (30% carbon fiber reinforced)

Molding process: profile machining

Features and advantages:

1: Femur and tibia distal aiming frame Generally, the overall structure is large. If metal is used, it will be particularly bulky, and the doctor’s surgical operation will be very inconvenient. The use of PEEK material can reduce 80% of the weight, greatly reducing the weight of the instrument and greatly improving the portability and flexibility of the doctor’s operation.

2: The distal end of the extended intramedullary nail will generally be deformed in the medullary cavity. Due to the light-transmitting properties of PEEK, the adjustable structure combined with the PEEK developer rod for distal positioning and aiming is more accurate and flexible.

Disadvantages:

1: The material must be heat treated in batches before and during processing. The internal stress of the material must be eliminated in time to avoid deformation after processing.

2: The processing of 30% carbon fiber reinforced PEEK is somewhat difficult. In addition to the large wear on the tool, the process requirements are also very high. Unreasonable processes can easily cause processing deformation and inability to aim.

3: The distal positioning frame of the adjustable aiming rod is too long, and the deviation after 100 disinfections is close to 0.05mm. It is recommended to switch to CF-PEEK sheet processing.
