Components: Adjustable aiming rod, crosshair, horizontal support
Material: PEEK5600CF30 (30% carbon fiber reinforcement)
Forming process: Profile machining
Features and advantages:
1. The femoral and tibial distal aiming frame is generally large in structure. If metal is used, it will be particularly heavy and inconvenient for doctors to operate. Using PEEK material can reduce the weight by 80%, which greatly reduces the weight of the instrument and greatly improves the ease and flexibility of doctors during surgery.
2: The distal end of the extended intramedullary nail will generally show some deformation within the medullary cavity. Due to the light-transmitting properties of PEEK, the adjustable structure combined with the PEEK imaging rod makes distal positioning and aiming more precise and flexible.
shortcoming:
1. Heat treatment should be performed on the material in stages before and during processing to eliminate internal stress in a timely manner and avoid deformation after processing.
Machining 2:30% carbon fiber reinforced PEEK is quite difficult. In addition to causing greater wear on the cutting tools, it also requires high-quality processing techniques. An improper process can easily lead to machining deformation and make it impossible to aim properly.
3: The remote positioning frame of the adjustable aiming rod is too long, and the deviation after 100 disinfection cycles is close to 0.05mm. It is recommended to switch to CF-PEEK sheet metal processing.
