TINY 5.5 Minimally Invasive Screw-Rod Internal Fixation System for the Posterior Approach of the Thoracolumbar Spine

Description

Innovative design combining soft and hard materials. The extension piece can break off automatically and can be used as a channel.
Unique design of the minimally invasive screw and the V-groove, which facilitates breaking and removal.
Design of guiding instruments makes the installation of the fusion device more convenient.

It provides a variety of unique and innovative minimally invasive screws for selection:

Hollow Pre-locked Multi-axial Reduction Screw

It has the flexibility of a universal screw, and after pre-locking, it has the stability of a fixed screw. It simplifies the implantation of the screw and the placement of the rod.

It is as easy to control as a fixed screw, and has better distraction and compression effects compared with ordinary multi-axial screws.

Nail-holding groove design: It is convenient for the operation of the pen-type reduction forceps. Without the need for precise alignment, the nail can be held in the nail-holding groove.

Hollow design: It is convenient for passing through the positioning guide pin.

Pre-locking structure: It is as easy to control as a fixed screw. When in the pre-locked state, the screw can be used for distraction and compression just like a uniaxial screw.

Hook-lock thread structure: It provides a better match during screwing in, avoiding thread misalignment and slipping, and completely preventing thread stripping and slipping.

Half-process double threads effectively increase the holding power of the screw.

Hollow swivel head reduction pedicle screw

After the screw body of the swivel head pedicle screw is fixed, the screw seat can rotate 360 degrees, facilitating the insertion of the connecting rod.

It is hollow, which makes it convenient to insert the positioning guide pin.
The double – threaded screw allows for a screwing speed that is twice as fast.

When inserting the rod into a uniaxial screw, the screw head needs to be retracted.

When inserting the rod into a swivel head screw, you only need to rotate the screw head.

Application: It is applicable to posterior distraction and compression, orthopedics, etc. of the lumbar and thoracic vertebrae. It can achieve effective distraction and compression effects, maintain the sagittal plane sequence, and fully distract the intervertebral space to facilitate the implantation of the intervertebral fusion device. It can also derotate the vertebral body and correct the vertebral body rotation deformity in the horizontal plane.
