Minimally Invasive Spine Fixation Device Posterior Thoracolumbar Screw-Rod Fixation System

A minimally invasive posterior thoracolumbar screw-rod fixation system is a surgical technique and associated set of instruments used for stabilizing the spine in the thoracic and lumbar regions. This system is designed to treat various spinal conditions, such as fractures, deformities, and instability.

The specific components and design of the system may vary depending on the manufacturer and the surgeon's preference. However, here are some common features and components of a minimally invasive posterior thoracolumbar screw-rod fixation system:

1. Pedicle Screws: Pedicle screws are specialized screws that are inserted into the pedicles of the vertebral bodies in the thoracic and lumbar spine. These screws provide the anchor points for the fixation system.

2. Rods: The system includes rods that are connected to the pedicle screws. These rods run parallel to the spine and are used to provide stability and alignment to the spinal column.

3. Connectors: Connectors are used to secure the rods to the pedicle screws. These connectors can be in the form of hooks, screws, or other specialized attachments.

4. Instruments: The system includes various surgical instruments specifically designed for the minimally invasive approach. These instruments are used to access the spine, prepare the pedicles, insert the screws and rods, and secure the construct.

5. Image Guidance: Minimally invasive posterior thoracolumbar screw-rod fixation is often performed under fluoroscopy or other imaging modalities to guide the accurate placement of screws and rods.

Product Design

• MIS Screw

The low profile design reduces the space occupation under the rod and the irritation to the surrounding soft tissue
Mechanically strengthened screw can greatly increase the contact area between screw and pedicle, and effectively improve the pullout force of screw
Tapered screw tip provides implant guidance function
Self-tapping is realized by full thread

• Extender Blade

The hard extender blade is easy to load and unload, the outer diameter is consistent with the screw, and the incision is smaller
C-Shaped screw base, which strengthens the connection stability and makes the rod passing easier

• Connection Rod

​Optimize the interface and tip design to make the rod holding and passing more stable and smooth.

• Screw Specification

Diameter 5.0 mm-7.5 mm
Length 25 mm-65 mm

Product Features

• Precise and Minimally Invasive, Safe and Time-saving

It can be used in conjunction with the "intelligent woodpecker" robot to significantly reduce the number of fluoroscopy, significantly reduce the operation time, and achieve sub-millimeter precision positioning.

• Automatic Guiding-into and Quick Implantation

Self-guiding and self-tapping thread make screw implantation faster.

• Optimized Design and Efficient Rod Passing

Through convenient extender blade design, optimized connecting rod end and interface form, and simple instrument combination, efficient rod passing operation is realized.

• Can Be Used with Other Parts of HicRen

With disposable puncture positioning plate, accurate fluoroscopy positioning can be carried out.
