Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, to detailed description of the invention of the present utility model, effect and operation principle etc. as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Fig. 6, this utility model provides a kind of anatomical form band ridge patellar prosthesis, comprise prosthese johning knot framework 1 and prosthese fixture 2, prosthese johning knot framework 1 is connected with prosthese fixture 2, prosthese fixture 1 comprises fixing short column 1-1 and fixing short column connecting plate 1-2, fixing short column 1-1 is connected with prosthese johning knot framework 2 by fixing short column connecting plate 1-2, prosthese johning knot framework 2 comprises Connection Bracket 2-1 and fixed connecting plate 2-2, Connection Bracket 2-1 is connected with fixed connecting plate 2-2, fixed connecting plate 2-2 lower end is connected with the fixing short column connecting plate 1-2 of prosthese fixture 1.
Preferably, prosthese johning knot framework 2 is eccentric dome-shaped structure, and Connection Bracket 2-1 is vault type structure, and the side curved edge of Connection Bracket 2-1 is connected with fixed connecting plate 2-2 edge.
Preferably, prosthese johning knot framework 2 is improvement dome-shaped, and Connection Bracket 2-1 is arcuate structure, Connection Bracket 2-1 center and fixed connecting plate 2-2 center superposition.
Preferably, prosthese johning knot framework 2 is for dissecting movable type structure, and Connection Bracket 2-1 is " people " font structure, and Connection Bracket 2-1 lower end is connected with fixed connecting plate 2-2, and the edge of Connection Bracket 2-1 is wider than the edge of fixed connecting plate 2-2.
