Abstract

The invention provides a navigation device for screw fixation. The device comprises a navigation template and a screw guide sleeve, wherein the screw guide sleeve is matched with an external guide tube of the navigation template and can be arranged in the external guide tube; the screw guide sleeve comprises a cylindrical screw guide body, a through hole for guiding a screw is arranged in the center of the cylindrical screw guide body, and accordingly, risk caused by deviation of screw fixation is reduced. Besides, the device further comprises a drilling guiding sleeve and a screw fixing unit, and the navigation template is fabricated with a 3D printing technology. The navigation device can more accurately guide the overall process of positioning, drilling and screw fixation, the individually designed navigation template can be adapted to various complex environments for screw fixation, and the accuracy and the safety of the overall process of screw fixation are further guaranteed.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a navigation device for placing nails. Background technique [0002] Nowadays, the technology used to build nails in the human body (such as pedicle screw internal fixation technology) has been widely used in the treatment of orthopedic trauma such as spine, orthopedics and other treatments. [0003] At present, clinically, a navigation template is usually used to guide the implantation of nails in human bone, and there are three steps in the implementation of a complete nail placement process, which are positioning of the broken bone cortex, drilling, and nail placement. However, the existing navigation template can only guide the pre-screw placement process, that is, the positioning of the cortex and the drilling process, that is, drilling at the designated position under the guidance of the original guide plate, and then inserting the screw in the cancellous bone of the spin...
