Description
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to a straight type coaptation board in olecranon outside.
Background
An olecroanon lateral straight locking plate is a bone fracture plate applied to the ulna lateral side when the olecroanon fracture is treated. After the olecranal fracture is reset, the olecranal fracture is fixed by using a bone fracture plate and a screw, and the olecranal fracture plate is matched with the L-shaped olecranal fracture plate on the inner side of the olecranal fracture for use to achieve the purpose of treatment. After reconstruction of anatomical relationship of the olecranal fracture, in order to reconstruct stability, a locking bone screw is adopted to fix the olecranal outer side straight locking plate and the olecranal inner side L-shaped locking plate. The locking bone screw is connected with a threaded hole in a locking hole on the bone plate through a conical double-line thread. When the olecroanon outer side straight bone fracture plate is used, the angulation of the locking screw during screwing in is consistent with the preset angle during processing of the bone fracture plate. However, the preset angle during the processing of the bone fracture plate does not necessarily conform to the complicated and changeable fracture type of the olecranon of the ulna. When a doctor selects a surgical plan, the plate shape of the bone fracture plate is consistent with the expectation of the doctor, but the situation that the surgical plan cannot pass through is caused because the screwing angle of one locking screw cannot meet the complex practical situation.
