Description
Technical Field
The utility model belongs to the field of medical instruments, and particularly relates to an anatomical locking steel plate for fixing the outer side edge of a scapula.
Background
With the rapid development of the transportation industry and the construction industry, the number of patients with high-energy injury is gradually increased, and the incidence rate of scapula fracture is increased. Because of the complicated anatomical morphology of the scapula, no steel plate specially used for scapula fracture exists at home and abroad at present. The steel plates for scapula fracture are all steel plates of other parts of the body, and are difficult to be compatible with the attaching degree and the fixing strength. Wherein, a 3.5mm system of a non-special steel plate is adopted, and often, 2 screws can be driven into the near end only reluctantly, so that the fixing strength is lacked; if a 2.5mm system screw is used, two steel plates are required, increasing the difficulty of the procedure. In particular to fracture of the outer side edge of the scapular neck, thick muscles, difficult dissection and exposure and extremely difficult effective fixation, which greatly increases the difficulty of surgical treatment of scapular fracture, prolongs the operation time and increases the operation trauma and the pain of patients. The combination of the prior literature and clinical practice shows that the key to the success of the operation is the reduction and fixation of the outer edge of the scapula in the surgical treatment of scapula fracture, so that the placement of a simple and effective scapula outer edge anatomical steel plate is urgently needed in clinical work.

Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
As shown in fig. 1 and 2, an anatomical-type locking steel plate for fixing the outer edge of a scapula of the present invention includes a scapula portion 10 and an outer edge portion 12. The outer rim portion 12 is an elongated structure having a first end 14 and a second end 16 connected to the glenoid portion 10, the second end 16 being a semi-circular structure. The scapular glenoid part 10 is a non-planar structure which is in conformity with the scapular glenoid part 10 of a human body, namely, a structure with a protrusion and a recess, and a proper shape can be preset at the beginning of production, and particularly, the scapular glenoid part 10 can be quickly matched by bending with small adaptability according to the actual physiological structure of a patient before an operation, so that the operation time is shortened.
The glenoid portion 10 and the outer edge portion 12 are integrally formed in a V-shaped configuration to match the shape of the scapula of a human body. Specifically, the method comprises the following steps: the scapular glenoid portion 10 includes four sides, in order: a first side 18, a second side 20, a third side 22, and a fourth side 24. The first side 18 and the second side 20, and the second side 20 and the third side 22 are connected by an arc. Wherein, the first edge 18 is connected with the second end 16 of the outer edge 12, and has a first included angle α with the length direction of the outer edge 12, and the optimal value of the first included angle α is 159 degrees, which conforms to the optimal shape of the human body; the fourth side 24 is connected to the second end 16 of the outer edge 12, and has a second included angle β with the length direction of the outer edge 12, and the second included angle β is 146 °, which conforms to the best shape of the human body. The structure not only conforms to the basic shape of the scapula of a human body, so that the scapula part is in fit with the scapula, but also enlarges the area of the scapula part as much as possible and increases the number of screw holes so as to meet the strength requirement.
The glenoid portion 10 is provided with 2 rows of second screw holes 28, each row being provided with 3 second screw holes 28, the diameter of the second screw holes 28 being 2.5 mm.
The second side 20 and the fourth side 24 are not parallel to each other, and an angle between extensions of the second side 20 and the fourth side 24 is an acute angle. The average spacing between the second side 20 and the fourth side 24 is about 2 times the width of the outer edge 12.
Above-mentioned structure for scapular pelvis portion 10 broad accords with the human characteristics that correspond the region and have more operation space, realizes fixing through two rows of screws of totally 6 2.5mm, has better fixed intensity. In a narrow working area corresponding to the outer edge portion 12, 4 screws of 3.5mm are used to reinforce the bonding strength, which results in high overall strength. In addition, the edges are all provided with guide angles, so that the edges are of arc structures, the surgical operation is easy to put in, and the harm to the human body is reduced.
