Description

Augmented reality device for fixing and positioning Kirschner nails

The present invention relates to an auxiliary device for Kirschner wires for treating fractures, in particular to an augmented reality device for fixing and positioning Kirschner wires.

Kirschner nail (or Kirschner wire) is a commonly used internal fixation material in orthopedics, with a length of about 20 cm and a diameter of about 0.5 to 2 mm. It is generally used for short fractures or avulsion fractures with low stress. Fracture fixation is also often used for temporary fracture fixation in orthopedic surgery. Due to its wide range of applications, the maximum diameter of Kirschner nails is gradually increased to 4 mm to fix fractures with greater stress such as pelvic fractures or humeral fractures.

However, in the process of implantation of Kirschner nails, repeated adjustment of the implant position and angle of the Kirschner nails will prolong the operation time, and may even damage the bone and affect the fixation effect. In order to improve the lack of implantation of Kirschner nails by the surgeon relying on experience, conventional techniques may require incisions to expose the joints and fractured areas for fixation during Kirschner nail implantation operations, causing damage to the soft tissues surrounding the fracture and more bleeding during the operation. Many patients have a long postoperative recovery time; or X-rays are used to reduce positioning errors, but it also relatively increases the risk of radiation exposure for patients and medical staff, making hospitals have to spend high costs to purchase navigation and intraoperative imaging equipment to avoid This risk.
