Safe Spine Fixation Device Vertebral Augmentation Screw-Rod Fixation System

A minimally invasive posterior thoracolumbar vertebral augmentation 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 combines the benefits of screw-rod fixation with vertebral augmentation, which involves the injection of bone cement into the fractured or weakened vertebrae.

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 vertebral augmentation 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. Bone Cement Delivery System: The system incorporates a bone cement delivery system, which allows for controlled injection of medical-grade bone cement, such as polymethylmethacrylate (PMMA), into the fractured or weakened vertebrae. This vertebral augmentation step helps restore vertebral strength and stability.

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

Product Features

• Advanced Bone Cement Outlet Design

Through the design of bone cement outlet, guide the flow of bone cement, improve the distribution effect of bone cement, and make the holding force of screws in the vertebral body of osteoporosis patients more powerful.

• Convenient Bone Cement Injection System

The bone cement injection system adopts threaded quick connection and one-step locking, which is convenient for operation.

• Arbitrary Switch Between Minimally Invasive and Open Mode

The operation of extender blade disassembly and assembly is simple and convenient, so that the bone cement screw can be implanted through minimally invasive percutaneous and open surgery to meet different clinical needs.

• Robot Empowerment

Cooperate with the "intelligent woodpecker" robot, plan the screw placement scheme, and complete the screw implantation by navigation.

• Can Be Used with Other Parts of HicRen

With disposable puncture positioning plate, accurate fluoroscopy positioning can be carried out.
Combined with HicRen bone cement and innovative injection device to achieve better bone cement distribution effect and operation experience.
