Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an orthopedic bone screw drilling positioning device. Background Art

[0002] Bone nails are non-active surgical metal implants for bone joining, consisting of cortical bone nails and cancellous bone nails. Currently, bone nails are widely used to stabilize new fractures, revision surgery, joint fusion, and reconstruction of small bones of the foot, ankle and toes. They can be used for adult and pediatric patients. Fracture is a common trauma. The commonly used treatment method is to insert bone nails into the fracture site, and then fix it with plaster and bandages and wait for it to recover. However, before implanting steel nails into the bone, a drilling device is needed to make holes.

[0003] Existing bone screw drilling devices are generally handheld, and the operation time is relatively long. The long-term holding causes the medical staff's arms to be unstable, which affects the progress of treatment and increases the drilling workload of the medical staff, causing increased burden on the doctor's arms. At the same time, slight movements and deviations of the patient's body will reduce the accuracy of drilling and cause other injuries to the patient, resulting in poor practicality.
