Percutaneous Curved Vertebroplasty System PCVP Curved Delivery Cannula

The innovator of new treatment for curved vertebroplasty technology

The percutaneous curved vertebroplasty system is a medical device designed for the treatment of vertebral compression fractures. It is a minimally invasive procedure used to stabilize and reinforce fractured vertebrae, reducing pain and improving the patient's quality of life.

This system consists of several key components:

1. Curved Needles: The system includes specially designed curved needles that are percutaneously inserted into the fractured vertebra under image guidance. These needles allow for precise placement of bone cement within the fractured area.

2. Bone Cement: The system utilizes bone cement, usually a polymethylmethacrylate (PMMA) compound, which is injected into the fractured vertebra. The cement hardens quickly, providing stability and support to the damaged bone.

3. Delivery System: The system incorporates a delivery system that facilitates the controlled injection of the bone cement through the curved needles. The system ensures accurate and controlled cement placement within the fractured vertebra.

4. Image Guidance: Typically, the procedure is performed under fluoroscopy or other imaging modalities to guide the placement of the curved needles and monitor the injection of the bone cement. This ensures accurate targeting and optimal cement distribution within the fractured vertebra.

Product Design

• Delivery Cannula

It is composed of PEEK material outer tube and nickel-titanium memory alloy inner core. After entering the vertebral body, it can recover the arc and reach the opposite side directly to realize unilateral puncture.

• Buckle

Guide the puncture direction of the delivery cannula, restrict the movement of the delivery cannula, and ensure the puncture safety

• Disposable Percutaneous Access Needle

Integrated puncture needle, which is easy to operate; small puncture diameter, which is safer

• Bone Cement Mixing Kit

​It is composed of a mixing device and an injection gun cylinder. After mixing, the bone cement can be continuously infused by a screw propulsion device without transfer, realizing the integration of mixing and infusion.

Product Features

• Unilateral Puncture, Integrally Forming

The PCVP system can establish an operating channel through unilateral puncture, send the delivery cannula to the opposite side of the vertebral body, withdraw the delivery cannula and infuse bone cement at different points in order to achieve continuous filling of the whole vertebral body, with low puncture risk and simple operation process.

• Multi-point and Low-pressure Infusion to Reduce the Leakage Rate of Bone Cement

The PCVP system can carry out multi-point infusion inside the vertebral body. The delivery cannula moves back while bone cement infusion, from point to face, with low infusion pressure, small diffusion range required for single point bone cement injection, and low leakage risk.

• Provide Full Vertebral Biomechanical Support

The bone cement of the PCVP system is distributed in an arc along the anterior edge of the vertebral body and evenly diffused in the vertebral body, so that the tiny fractures in the vertebral body can be fixed, and the stimulation of the pain nerve at the fracture end can be avoided, and the patient's pain can be reduced. At the same time, the stress area of bone cement is larger and more balanced, which can effectively avoid vertebral collapse and adjacent vertebral fracture, and has excellent long-term effect.

• Simple Technique, Less Number of Fluoroscopy and Shorter Operation Time

Through the vertebral pedicle approach, the PCVP system does not need to move the puncture point outward or increase the puncture angle inward. The operation is simple, the technical requirements are low, and the number of fluoroscopy is reduced. At the same time, the operation time is greatly shortened to avoid complications caused by patients lying on the operating table for a long time.
