After the steel wire 3 is screwed into the second groove 213, the tail of the steel wire 3 can be cut off, bent, and sewn to the wound.
As shown in FIG. 8, the two steel plate fixing systems 100 of the present invention are used to perform a cross fixation reduction on both sides of the fracture site, thereby achieving a balanced fixation effect.
To sum up, the present invention comprises a first steel plate 1, a second steel plate 2 and a steel wire 3, wherein both ends of the steel wire 3 are inserted into a first through hole 111 and a second through hole 112 from a first surface of a first steel body 11, respectively, and then are extended out from a second surface of the first steel body 11, and then are inserted into a first through hole 131 of a first positioning portion 13 and a second through hole 141 of a second positioning portion 14, respectively, such that both ends of the steel wire 3 are converged at a position corresponding to a middle portion of the first steel body 11, the first steel plate 1 is guided into a fracture block in a joint cavity by pulling the steel wire 3 along a predetermined route, and then the steel wire 3 is extended out from one of the bone passages of the bone block and is extended out of the bone, such that both ends of the steel wire 3 are inserted into a third through hole 211 and a fourth through hole 212 from the second surface of the second steel body 21, respectively, and then both ends of the steel wire 3 are tightened and screwed onto the second surface of the second steel body 21, the second fixing portion 22 of the second steel plate 2 is fixed outside the bone, so that the steel plate fixing system 100 of the present invention can be formed; compared with other fixing methods which are directly operated under an arthroscope, the steel plate fixing system 100 has small requirement on operation space and convenient operation, is suitable for operation under the arthroscope, and can not be operated under the arthroscope without the situation that the steel wire can not be operated when the steel wire 3 is inserted into a bone channel and is connected with the second steel plate 2; the first steel plate 1 is fixed at the position of a fracture block to fix the fracture block, and the second steel plate 2 is fixed on the fracture block under the connecting action of the steel wire 3 to realize the positioning of the first steel plate 1 and ensure that the first steel plate 1 can be stably fixed at the position of the fracture block, so that the fracture block can be effectively fixed and the resetting effect is improved; in the same operation mode, the first steel plate 1 of the other set of steel plate fixing system 100 is fixed on the other side of the fracture block, and the two sets of steel plate fixing systems 100 are in a cross mode, so that the fracture block can be further effectively fixed and the resetting effect can be further improved.
The above disclosure is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, so that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
