MIS Screw Extender Blade Spine Fixation Device Vertebral Fixation Device

Fixation of the spine by percutaneous minimally invasive means, combined with an upgraded tool combination, makes in vitro operation more convenient, and can be used for conventional minimally invasive percutaneous internal fixation and bone cement enhanced fixation.

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.
