Description
Technical Field
The invention relates to the technical field of orthopedic devices, in particular to an adjustable pelvic fracture fixing steel plate.
Background
Surgical treatment after pelvic fractures is most common, with the primary embodiment being fixation by internal fixation plates/titanium plates. In order to meet the requirement of pelvic fracture internal fixation in different forms, some steel plates need to be bent, some steel plates are reminded to be large, a section of supporting steel plate can be fixed between two sections of steel plates after part of the fixing steel plate/titanium plate is bent, the position of the section of supporting steel plate is matched with the bone surface on the back surface of the acetabulum, an effective supporting effect is formed on the back surface of the acetabulum, the structural strength of the bent steel plate/titanium plate is enhanced, small-wound surgery cannot be performed on the steel plates when the steel plates are used, and incision restoration and steel plate screw internal fixation are required. The traditional incision operation can obviously expose the fracture part, but the operation range is large, the soft tissue damage is heavy, the operation time is long, the bleeding is much, and serious vascular nerves can be damaged.
Therefore, how to provide a fixed steel sheet of pelvis fracture, can fold the less structure of formation before getting into it internally, reduce its space that occupies, so that cut a little incision on the health and can be internal with it immigration, it uses to expand again after getting into internally, the angle of expansion is adjustable, be fit for satisfying different skeleton morphology demands, then carry out steel sheet screw internal fixation again, reduce fracture position exposure, reduce the operation scope, the protection soft tissue, shorten operation time, reduce the amount of bleeding, avoid damaging great vascular nerve, this technical problem that the skilled person in the art needs to solve urgently.
