Scapula locking plate

Technical Field

The utility model relates to the technical field of medical equipment, in particular to scapula lockplate.

Background

The scapula is also called as a scapula and a lute bone, is positioned behind the thorax, is between the 2 nd to 7 th ribs and is a triangular flat bone. The scapula comprises two faces, three corners and three edges, wherein the front face is a subscapular fossa which is a large and shallow fossa; the back of the spine is provided with a transverse bone ridge called as a scapular spine, shallow pits above and below the spine, called as supraspinatus pit and infraspinatus pit respectively, the outer side of the scapular spine is flat, called as acromion, is hypertrophic in the outer corner of the highest point of the shoulder, and is provided with a pear-shaped articular surface called as a glenoid; the upper corner and the lower corner are positioned at the upper end and the lower end of the inner side edge, are respectively aligned with the 2 nd rib and the 7 th rib and can be used as marks of counting ribs; the medial aspect is long and thin, facing the spine, the lateral aspect is thick, facing the axilla.

The classification system of scapulae is relatively complex, no unified classification standard exists at present, and common classification methods include Hardegger classification, Mille classification and classification of bone trauma orthopedics Association of International internal fixation research (AO)/OTA (OTA), wherein the Hardegger classification can be specifically divided into scapula body fracture, scapula pelvis marginal fracture, scapula glenoid fossa fracture, anatomical neck fracture, surgical neck fracture, acromion fracture, scapula spine fracture and coracoid process fracture. The geometrical shape of the scapula is very irregular, the anatomical position is deep, and the number of muscles attached is large, so the probability of fracture nonunion is high, after the scapula fracture is healed, on one hand, the fracture is determined by the damage degree of the fracture, on the other hand, close relation is formed between the scapula fracture and good operation reduction and fixation, and the types of selectable materials for internal fixation treatment are more, such as: reconstruction steel plate, T-shaped steel plate, deformed steel plate, calcaneus steel plate, Kirschner wire, steel wire, absorbable and non-absorbable screw and the like.

Chinese utility model patent with publication number CN2757744 discloses a scapula dissection type steel plate, which is a thin plate, the shape of which is adapted to the physiological dissection shape of scapula, and the shape of which is like two T-shaped steel plates, which can respectively three-dimensionally fix the outer edge of scapula, scapula pelvis and scapula spine together. The steel sheet is the plane before using, can carry out moulding according to the scapula appearance during the use, and the design has a plurality of screw fixation holes and a screw fixation regulation hole on the steel sheet. The steel plate is a titanium steel plate, is thin and elastic, has good strength, is close to the elastic modulus of bones, and is easy to be arranged in the operation.

However, the steel plate needs to be bent, twisted, cut off and the like according to the appearance of the scapula during the operation, the steel plate structure is integral and is not easy to bend, and particularly, a special steel plate is not provided for the fracture part between the scapula spine and the infraspinatus at present, so that great inconvenience is brought to a doctor during the operation, and meanwhile, the fracture part between the steel plate and the scapula spine cannot be well attached and fixed, so that the postoperative recovery effect of the patient is influenced.
