DETAILED DESCRIPTION

[0021] As Figures 1-4 shown, the utility model discloses a combined loop titanium plate, including inner fixation plate 1, be equipped with a plurality of fixed holes 2 on inner fixation plate 1, the purpose of fixed hole 2 is, the mode of screw is used to fix inner fixation plate 1 on the fixed part 15 of patient (bone), wherein the inside of one of fixed holes 2 is equipped with mounting plug 4, which fixed hole 2 is, can judge according to patient time condition, then process inner fixation plate 1, the inner wall of selected fixed hole 2 is equipped with first internal thread 3, the outer surface of mounting plug 4 is equipped with first external thread 5, mounting plug 4 is connected in fixed hole 2, the inside of mounting plug 4 is equipped with arc-shaped groove 7, the purpose of arc-shaped groove 7 is to make part loop rope 14 be located in it, and the rotation and movement of loop rope 14 are limited, preferably, the both ends of arc-shaped groove 7 are from the side of inner fixation plate 1 and the fixed part 15 of patient contact and go out, the mounting plug 4 on the both ends of arc-shaped groove is all equipped with lateral through groove 16, the purpose of lateral through groove 16 is, the passage and installation of loop rope 14 are convenient, the inside of arc-shaped groove 7 is equipped with loop rope 14, loop rope 14 passes through arc-shaped groove 7, and loop titanium plate 13 is equipped on the both ends of loop rope 14 located the outside of arc-shaped groove 7, and the both ends of loop rope 14 are fixedly connected on loop titanium plate 13.

[0022] The working principle of the above technical solution is:

[0023] When the fixed part 15 of patient needs to be fixed by inner fixation plate 1 and loop titanium plate 13 at the same time, the inner fixation plate 1 and loop titanium plate 13 can be used in combination according to the mode in the present solution, which avoids the mutual interference of the inner implants when the traditional loop titanium plate 13 (having two loop titanium plates 13, one of which contacts the inner fixation plate 1) is used with the inner fixation plate 1, and avoids the risk of metal electrolysis or loop fracture caused by the micro-motion of the two.

[0024] In an implementable mode, the upper middle part of mounting plug 4 is provided with mounting hole 6, the bottom surface of mounting hole 6 is provided through arc-shaped groove 7, locking plug 9 is arranged in mounting hole 6, the outer surface of locking plug 9 is provided with second external thread 10, the inner wall of mounting hole 6 is provided with second internal thread 8, when locking plug 9 is threadedly connected in mounting hole 6, the end of locking plug 9 abuts loop rope 14 in mounting hole 6 against the bottom surface of mounting hole 6.

[0025] The purpose of the locking plug 9 is to press and fix the position of the loop rope 14 in the part of the installation hole 6 after the inner fixation plate 1 and the loop titanium plate 13 are installed in place, that is, the bottom end of the locking plug 9 is pressed and fixed to the position of the loop rope 14 in the installation hole 6, so as to avoid the problem of easy friction and breakage of the loop rope 14 in the installation hole 6.

[0026] In an implementable manner, the inside of the installation hole 6 is provided with a sliding plate 12 between the loop rope 14 and the end of the locking plug 9 in the installation hole 6.
