An orthopedic drilling fixation device

Abstract

The invention discloses an orthopedics drilling fixation device. The device comprises upper fixation rings and lower fixation rings, wherein the upper fixation rings and the lower fixation rings are both of a semicircular shape, the number of the upper fixation rings and the lower fixation rings are both two, and middle axes of the upper fixation rings and the lower fixation rings are coincident; protrusion blocks are arranged on the edges of the upper fixation rings and the lower fixation rings, through holes are formed in the protrusion blocks, the upper fixation rings and the lower fixation rings are connected through screws which are arranged in the through holes, and nuts are arranged on the outer portions of the screws in a sleeving mode; the orthopedics drilling fixation device is relatively small and exquisite in structure, the occupied incision space is not large, large-scale periosteum stripping on patients can be avoided, the blood supply on fractures cannot be influenced, and subsequent drilling operation and screwing operation cannot be influenced; the orthopedics drilling fixation device can further adjust different fixation inner diameters according to different thicknesses of bones which need fixation and restoration, is high in convenience degree and applicability and further provided with a drilling aiming device, and avoids the harm for the patients caused by wrong positions during drilling.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an orthopedic drilling fixation device. Background technique [0002] Human extremity fractures are one of the most common clinical manifestations of orthopedic trauma. Internal fixation of fractures is a comprehensive treatment based on restoration of anatomical relationship, stable fixation, preservation of bone blood supply and early functional activities as much as possible. In the prior art, screw fixation and reduction are often used when the limbs are fractured. During the operation, the fixation device is used to fix the hole, and then the screw is used for reduction and fixation. However, most of the existing fixation devices are bone clamps, but the bone clamp It is large in size and occupies a large incision space, so it will not only affect the subsequent drilling operation and screw insertion operation, but also require a large periosteum stripping range, whi...

[0002] Human extremity fractures are one of the most common clinical manifestations of orthopedic trauma. Internal fixation of fractures is a comprehensive treatment based on restoration of anatomical relationship, stable fixation, preservation of bone blood supply and early functional activities as much as possible. In the prior art, screw fixation and reduction are often used when the limbs are fractured. During the operation, the fixation device is used to fix the hole, and then the screw is used for reduction and fixation. However, most of the existing fixation devices are bone clamps, but the bone clamp It is large in size and occupies a large incision space, so it will not only affect the subsequent drilling operation and screw insertion operation, but also require a large periosteum stripping range, which will affect the blood supply to the fracture. In addition, clinically, it often needs to be fixed and reset as needed. It is troublesome to use clamps with different inner diameters for different bone thicknesses.
