Fracture Reduction Robot

Fracture surgery assisting robot system

In conventional fracture surgery, the state of the fracture is confirmed by radiographic imaging, and the medical staff pulls the broken part from the outside and aligns the bone.

At this time, a fixing pin is inserted into the broken bone fragment so that the doctor can hold the pin and move it to proceed with reduction.

Unlike existing products, this device connects a hexapod-type device that can be operated by a motor to a fixing pin inserted into a bone fragment , and adjusts the bone fragment with an adjuster for accurate fracture reduction.

It can protect the doctor from the risk of radiation exposure from the C-arm, involving high strength and low weight characteristics.

Existing fracture surgery relies on the C-arm image (2D), which can make accurate 3D correction difficult; therefore, involving a risk of excessive radiation exposure to medical staff.

To solve these problems, the fracture robot system is an ultra-precise modular restoration system that can perform minimal invasive surgery within a short time while minimizing radiography.
