Description
Technical Field
The utility model relates to the technical field of medical appliances, in particular to a phalangeal locking bone fracture plate.
Background
The phalangeal locking bone fracture plate is a bone fracture plate applied to the outer side of phalangeal bone when the phalangeal fracture is treated. After the phalangeal fracture is reset, the damaged phalangeal is fixed by using the locking bone fracture plate and the screw, so that the purpose of auxiliary treatment of the phalangeal fracture is achieved.
After the anatomical relationship of the phalangeal fracture is reconstructed, the locking bone screw and the cortical bone screw are adopted to fix the locking bone plate at the outer side of the phalangeal for reconstructing stability. The locking bone screw is connected with a threaded hole in a locking hole on the bone plate through conical double-line threads. When the phalangeal locking bone plate is used, the angulation of the locking screw when the locking screw is screwed in is consistent with the preset angle when the bone plate is processed. However, the preset angle during processing of the bone fracture plate cannot necessarily meet the complex and changeable fracture types of the phalanges. When a doctor selects an operation scheme, the plate shape of the bone plate may be expected by the doctor, but the operation scheme cannot pass because the screwing angle of a certain locking screw cannot be matched with the complicated actual situation. Therefore, the screw-in angle reserved by the phalangeal bone fracture plate existing in the market at present often cannot meet the complicated actual operation condition.
In addition, the existing phalangeal bone fracture plate structure on the market is difficult to fit the physiological radian of the fracture part of a patient, cannot meet the requirement of the patient, and cannot be completely attached to diseased bone of the patient.
