Description
Technical Field
The invention relates to the technical field of bone plates, in particular to a phalangeal bone plate.
Background
In clinic, middle phalangeal fracture is common, and two phalangeal bones of the fracture are usually fixed by using a strip-shaped bone fracture plate; however, for the stability of fixation, the long-strip bone fracture plate generally needs to be provided with 4 locking screws at intervals along the length direction of the bone fracture plate, namely 2 locking screws are respectively arranged on two fractured phalanges, so that the long-strip bone fracture plate is only suitable for the fracture condition that a fracture crack is positioned in the middle position of the middle phalanges; for the situation that the fracture crack is close to the distal end or the proximal end of the phalangeal bone, a T-shaped bone fracture plate or an I-shaped bone fracture plate is mostly used clinically; when the T-shaped bone fracture plate is used, the big head end of the T-shaped bone fracture plate corresponds to the shorter one of two sections of fractured phalanges, and two locking screws are arranged at the big head end of the T-shaped bone fracture plate so as to ensure the stability of fixation; because two locking screws are required to be installed, the big head end of the T-shaped bone fracture plate is larger in size, the influence on the finger bone joint of a patient is larger, if the I-shaped bone fracture plate is used, the influence on the finger bone joint of the patient is larger, and the tendon of the finger bone of the patient is easy to lengthen after the bone fracture;
chinese patent (bulletin number: CN 214231486U) discloses a bone plate device; the patent phalangeal bone fracture plate is of a T-shaped structure, two locking screws are arranged at the big end of the bone fracture plate, the size is large, the influence on the knuckle of a patient is large, and the bone fracture plate is not beneficial to recovery of the patient;
chinese patent (bulletin number: CN 104127228A) discloses a surgical bone plate with sustainable elastic active compression; the patent designs a hollow elastic hole in the middle of the existing bone fracture plate (usually the fracture part needing to be fixed); the elastic hole is deformed under the action of the pressurizing screw hole or the pressurizer, so that active pressurizing of the proximal and distal ends of the fracture is generated; meanwhile, the hollow design of the elastic hole can reduce the effect of stress shielding through deformation; the elastic hole of the patent needs to deform under the action of a pressurizing screw hole or a pressurizer, is inconvenient to operate, and can cause secondary fracture or fragmentation of the phalanges when the weak phalanges are actually operated.

Detailed Description
The present invention will be explained in detail by the following examples, and the purpose of the present invention is to protect all technical improvements within the scope of the present invention, and in the description of the present invention, it should be understood that if there is an orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", etc., only correspond to the drawings of the present application, and in order to facilitate description of the present invention, it is not necessary to indicate or imply that the apparatus or element referred to has a specific orientation.
Example 1, with reference to fig. 1, a phalangeal bone plate comprises a bone plate body 1 and wrapping wings 2; the two sides of the bone fracture plate body 1 are respectively provided with wrapping wings 2 used for encircling the phalanges, the two ends of the bone fracture plate body 1 are respectively provided with locking holes 3 used for installing screws, when the bone fracture plate is used, the two ends of the bone fracture plate body 1 respectively correspond to two fractured phalanges, the locking screws are installed in the two locking holes 3, the two fractured phalanges are axially positioned through the bone fracture plate body 1, then the two wrapping wings 2 are bent through the clamp to encircle the two fractured phalanges, the two phalanges are radially positioned, the fixation stability is good, the patient recovery is facilitated, and the wrapping wings 2 are good in wrapping performance and can be applied to the situation that the phalangeal fracture is positioned at the middle position and the fracture is close to the distal end or the proximal end of the phalanges; the end part of the bone fracture plate body 1 is only provided with one locking screw, so that the bone fracture plate is small in size and small in influence on phalangeal joints; in addition, the two ends of the bone fracture plate body 1 are of slope structures, so that the influence on the extensor tendons of a patient can be further reduced.
