The second fixing hole 121 is a universal locking hole, so that the operation of a doctor is convenient in the operation, and the fastening of screws can be realized in a plurality of directions.
In other embodiments, the second fixing hole 121 may also be a combination hole or a long pressing hole, and when the second fixing hole 121 is set as a long pressing hole, the position of the screw can be flexibly determined, so that the screw can be inserted into a thicker position of the lower inner side edge 3, or the screw can be inserted into a position with a recess on the lower inner side edge 3, so as to ensure the adhesion of the second fixing plate 12 and the lower inner side edge 3. When the second fixing hole 121 is a combining hole, a doctor can select a locking screw or a leather nail according to specific conditions during operation, so that the fixing effect is better.
In other embodiments, the second fixing hole 121 can also be selected as a locking hole with a single axis, and the axis of the second fixing hole 121 and the bone plate body 1 are arranged at an included angle ranging from 70 degrees to 90 degrees, such as 75 degrees, 78 degrees, 80 degrees, 85 degrees or 88 degrees, so that the axis of the second fixing hole 121 is biased to a position where the lower inner side edge 3 of the scapula is thicker, and therefore a longer screw can be selected to enter the screw, which is beneficial for increasing the length of the screw in the scapula 2, and therefore the holding force of the screw on the scapula is increased.
In the present embodiment, each of the second fixing holes 121 may be a locking hole, a coupling hole, or a long pressurizing hole. As shown in fig. 5, the second fixing holes 121 are all combination holes.
In this embodiment, the diameters of the first fixing hole 111 and the second fixing hole 121 may be selected to be 2.4mm, 2.7mm, or 3.5mm locking holes, and the screws are selected to be locking screws, which can be well connected to the bone plate body 1 and screwed into the spine 2.
In the present embodiment, the connecting portion 13 is a curved surface having a length of 10mm to 25mm, and can be satisfactorily fixed to the junction between the lower inner edge 3 of the scapula and the scapular spine 2, thereby reducing irritation of the bone fracture plate body 1 to the surrounding musculature and avoiding discomfort of the patient.
In this embodiment, the first fixing plate 11, the second fixing plate 12 and the connecting portion 13 are integrally formed, and may be formed by casting or milling. The included angle between the surface of the first fixing plate 11 and the surface of the second fixing plate 12 is 45-90 degrees, and the included angle can be selected to be 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees or 85 degrees according to specific requirements, so that the bone fracture plate body 1 can be better attached to the scapula.
In the present embodiment, the thickness of the bone plate body 1 is 1.3mm-2.5mm, for example, 1.5mm, 1.8mm, 2.0mm or 2.3mm, which can be selected according to specific needs.
The bone fracture plate body 1 is made of pure titanium or titanium alloy by casting. The pure titanium or titanium alloy material has good histocompatibility, is close to the elastic modulus of human skeleton, has little reaction and is beneficial to the recovery and the activity of the body of a patient. It should be noted that the bone plate body 1 in this embodiment is not limited to the above two materials, and other materials may be freely selected according to actual conditions to achieve the functions of light weight and small immune rejection.
In this embodiment, 1 edge of coaptation board body is the fillet structure, specifically, is the fillet structure between the one side that the scapula was kept away from to coaptation board body 1 and coaptation board body 1 side for reduce coaptation board body 1 and irritate the soft tissue of scapula avris.
