Embodiment Construction

[0012] The present invention will be further described below in conjunction with drawings and embodiments.

[0013] figure 1 , 2 As shown, a humerus Y-shaped protective plate includes a straight section 1, a fork 2, a protective wing 3, a threaded hole 4, a locking pressure hole 5, a countersunk screw 6 and a countersunk pressure screw 7, the straight section 1 and the two The connection of the fork 2 is an inverted Y-shaped structure in which the medial surface coincides with the distal end of the humerus. A plurality of protective wings 3 are arranged symmetrically on both sides of the straight section 1, and the protective wings 3 are in the shape of wrapping toward the inner side of the straight section; There are a plurality of locking pressure holes 5, and the locking pressure holes 5 are provided with countersunk head pressure screws 7 screwed to the humerus 8, and the fork legs 2 and the protective wings 3 are provided with a plurality of threaded holes 4, and the thr...

Abstract

A humerus Y-type protection steel board is formed by connecting a straight section and two forks and is in an inversed-Y-type structure with the inner side face and the far end of the humerus being matched, and a plurality of locating holes are formed in the straight section and the forks. The humerus Y-type protection steel board is characterized by further comprising a plurality of protection wings which are symmetrically arranged on the two sides of the straight section and are in a contained shape towards the inner side face of the straight section; when the straight section is fixed to the far end of the humerus, the inner side face of the straight section is attached to the front face of the far end of the humerus, the two sides of the protection wings wrap the two sides of the far end of the humerus in a containing mode, crush bones on the two sides of the humerus can be stably fixed in the mode that screws or fixing needles penetrate through threaded holes or needle penetrating holes, the completeness of the humerus is protected, and the fracture healing and treatment effect of the humerus is improved; countersunk head screws are flat on the surface of the steel board when used, no protrusion exists, implantation is convenient, pains caused by use of the screws are relieved, and postoperative healing is facilitated; the locking firmness is improved through a countersunk forcing screw.

Description

technical field [0001] The invention relates to the field of implant instruments, in particular to a humeral Y-shaped protective steel plate. Background technique [0002] In modern orthopedic surgery, most humeral fractures are fixed by plate implantation. For example, the patent No. 201320385306.4 discloses a locking plate on the dorsal side of the distal end of the humerus. Locking holes and locking pressurization combined holes are set on the Y-shaped steel plate, and locking screws and The compression screw locks the locking plate on the dorsal side of the distal humerus, and the locking plate is fixed on the humerus stably, but it only has a good fixation effect on the broken bone on the dorsal side of the humerus, and it cannot fix the broken bone on both sides of the humerus. It uses broken bone The location is limited and the scope of application is small. Contents of the invention [0003] Aiming at the deficiency in the prior art that the broken bones of the hu...
