Minimally invasive calcaneal fracture fixing nail guiding system and using method

Abstract

The invention provides a minimally invasive calcaneal fracture fixing nail system and a using method, and belongs to the technical field of medical instruments. The invention provides a minimally invasive calcaneal fracture fixing nail guiding system. The minimally invasive calcaneal fracture fixing nail guiding system comprises a first hollow bone screw, a second hollow bone screw, a guiding plate and a guiding needle. The first hollow bone screw is implanted from the inner upper part of the rear side of the calcaneus to the front outer part of the calcaneus, the second hollow bone screw is arranged below the first hollow bone screw and is implanted from the outer lower part of the rear side of the calcaneus to the sustentaculum tali direction of the inner upper part of the calcaneus, and the first hollow bone screw is detachably connected with the guide plate; the guide plate is provided with a guide hole for the guide needle to penetrate through, and the second hollow bone screw is provided with a through hole matched with the guide needle in the axial direction of the second hollow bone screw. And the guide plate is attached to the surface of the calcaneus. According to the minimally invasive calcaneal fracture fixing nail guiding system and the using method, the number of nail holes is small, operation is easy and convenient, damage to a patient is small, and popularization is easy.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a minimally invasive calcaneal fracture fixation nail guiding system and a method of use. Background technique [0002] Calcaneal fractures are the most common tarsal fractures. During the treatment of calcaneal fractures, reduction and fixation of the fracture site are crucial. At present, plate screws or bone screws are generally used to fix the fracture site. When using plate screws for fixation, the surgical incision is large, which is prone to surgical complications, easily causes skin necrosis, wound infection, and causes greater harm to patients; using bone screws During fixation, the surgical incision is small and the reduction operation is easy. However, in the process of implanting bone screws, due to the irregular shape of the calcaneus, it is difficult to locate the position of the bone screws, so X-ray imaging equipment is often used to assist pos...
