Adjustable aiming bracket for femoral intramedullary nail

Femur: Adjustable aiming rod, lateral support

Material: PEEK5600CF30 (30% carbon fiber reinforced)

Forming process: profile machining

Features and advantages:

1: The femoral and tibia distal aiming frames generally have a large overall structure. If metal is used, it will be very bulky, which makes it very inconvenient for doctors to perform surgery. The use of PEEK material can reduce the weight by 80%, greatly reducing the weight of the equipment and greatly improving the portability and flexibility of the doctor’s surgery.

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

shortcoming:

1: The material must be heat treated in several times before and during processing. The internal stress of the material should 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 process can easily cause processing deformation and loss of aiming.

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