器械套装：
- Universal Pedicle Screw Instrument Set
- Hobbit 5.5/6.0 Instrument Set
- Hobbit 5.5/6.0 Optional Instrument Set
特点：
Compatible with 5.5/6.0 System, higher Fixation Strength
- Secure assembly
- Both 5.5mm and 6.0mm rod can apply to the same pedicle screw
Thread Design
- Proximal thread for cortex bone: enhance pedicle fixation
- Self-tapping thread of screw tip: easy insertion of the screw into the pedicle; non-tapping design of the slot without damage to the pedicle wall makes the bicortical fixation safer (except S2AL)
- Double-threaded design: improve insertion speed
Screw Head Design:
Minimum volume of screw head
- Avoid difficulty of postoperative suture and complications such as wound pain caused by high profile
- Reduce irritation to the adjacent bone structure.
- CBT avoids collision between screw heads.
Screw Arm Design
- Rectangular thread: reduce cross threading
- Negative angle of thread: avoid distraction and rupture of the screw arm
- Blunt design of the beginning part: automatic alignment can be realized without the alignment sleeve
Screw Nut Design:
- Snap-off screw nut: avoid slippery
- Protruding point: increase the compression between the screw nut and the rod and improve the locking ability
- Sand blast: Anti-reflection; Increase friction and reduce the risk of detachment.
Uni-Planar Pedicle Screw
- The best pedicle screw for derotation
- Easy insertion of rod
- Fixed plane for better correction
S2AI Screw
- A kind of spinal pelvic internal fixation
- The screw passes through S2s acralwing, sacroiliac joint and iliac bone plate
- In alignment with the S1 pedicle screw, no need for a switch when connecting with S1
- Low profile design, low risk of exposure of screw end
- Triple cortical fixation
Double-headed Pedicle Screw
- Spine osteotomy
- Revision surgery
- Lumboscral Fixation
