An anatomical plate system for quadrilateral fractures of the anterior column of the acetabulum

Abstract

The invention provides an anatomical steel plate system for quadrilateral fractures of the anterior column of the acetabulum, which relates to the technical field of orthopedic surgical instruments, and comprises a steel plate and a shaper for shaping the steel plate. The steel plate includes a fan ring-shaped steel plate body and a number of fixing holes distributed on the steel plate body, a widening portion is arranged outside the middle of the steel plate body, and fixing holes are distributed on the widening portion. The shaper comprises a lead screw and a lead screw nut matched with the lead screw. Two arms are arranged symmetrically on both sides of the lead screw nut. The middle part of each arm is hinged on the lead screw nut. The bottom pivot is connected with a claw buckle and the top is slidably connected in the measuring ruler frame, and the limit spring is connected between the support arm and the screw nut; the top of the screw is connected to the motor, and the motor is fixed on the hand-held frame. The invention solves the problem in the prior art that the acetabular fracture anatomical steel plate cannot fit well with the bone surface according to the individual differences of the injured.

Description

technical field [0001] The invention relates to the technical field of orthopedic surgical instruments, in particular to an anatomical plate system for quadrilateral fractures of the acetabular anterior column. Background technique [0002] The acetabular fracture involves the quadrilateral, and the quadrilateral fracture often shifts into the pelvis together with the proximal part of the anterior column. Fractures of the anterior column are often combined with the anterior wall and the quadrilateral body. The bone surface of the quadrilateral body is the bony plane that forms the outer edge of the true pelvis. Some anatomical steel plates cannot fit the bone surface well, which is likely to cause complications such as poor internal fixation, wrong screw placement or failure. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides an anatomical plate system for acetabular anterior column quadrilateral frac...
