Detailed Description
The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
A percutaneous reduction screwing retractor is shown in figures 1 to 2 and comprises a top head 1, a fixed rod 2, a first holding rod 3 and a second holding rod 4.
Be equipped with two through-holes 101 in the top 1, two through-holes 101 correspond a tying up rope (the steel wire is commonly used in hospital) respectively, and smooth polishing treatment need be done to the front end of top 1, and it needs disinfection when using.
The front end of the fixed rod 2 is fixedly connected with the top head 1, the front end of the top head 1 is small, the rear end of the top head is large, the front end of the top head faces the incision of the operation, and the rear end of the top head is fixedly connected with the front end of the fixed rod 2.
The first holding rod 3 is arranged at the rear end of the fixed rod 2, and the second holding rod 4 is arranged in the middle of the fixed rod 2 and used for pulling the binding rope passing through the through hole 101 of the top 1 to the direction of the first holding rod 3. Two ends of the binding rope penetrate through the top head 1 and then are fixed on the second holding rod 4, and under the auxiliary action of the second holding rod 4, the binding rope is lifted, so that the binding rope is tightened at the fracture part.
With respect to the above mentioned operation of lifting the binding-rope, the present application provides two solutions for reference, one of which: the second holding rod 4 is provided with a through groove 401 opposite to the through hole 101, and a locking screw 5 is arranged in the through groove 401 of the second holding rod 4. The rope binding is fixed in logical groove 401 through the inner of locking screw 5, through the effect that first holding rod 3 was carried and is drawn, and the steel wire is taut to first holding rod 3 department, can transfer locking screw 5 afterwards, continues taut fixedly with the rope binding. Preferably, the inner end of the locking screw 5 is provided with a fixed line hole 501, the end part of the binding rope is fixed on the fixed line hole 501, and the locking screw 5 is rotated to complete the tensioning of the binding rope. In the above technical solution, the second holding rod 4 is preferably fixedly arranged with the fixed rod 2. Or preferably, the side surface of the second holding rod 4 is provided with an open slot 402, the open slot 402 is communicated with the through slot 401, and the binding rope can be directly placed into the through slot 401 from the side surface of the second holding rod 4, so that the operation is convenient and fast. The second step is as follows: second holding rod 4 and fixed pole 2 slip setting, fix the wiring on second holding rod 4, thereby forefinger and middle finger upwards pull second holding rod 4 taut wiring. Preferably, the second holding rod 4 is provided with a locking rod 6, and the inner end of the locking rod 6 is abutted against the fixed rod 2. The second holding rod 4 can be fixed on the fixed rod 2 at any time by using the locking rod 6. In the two schemes, the outer end of the locking screw 5 is provided with the operation hole 502, so that the locking screw 5 with smaller size can be conveniently operated.
When the percutaneous reduction screwing retractor is used (all tools are disinfected in advance), a cut is made at a local fracture part, after a steel wire is placed on the surface of a bone through special instruments, two end parts of a tying rope (steel wire, hereinafter referred to as steel wire) tied at two fracture ends respectively penetrate through the through hole 101 of the top head 1 and are fixed on the second holding rod 4, the two holding rods are lifted, the distance of the steel wire is reduced through the opposite movement of the steel wire and the retractor, the deformation of the steel wire on the surface of the bone is increased, and the fracture reduction is facilitated; the steel wire is pressed through the two sets of operations of pulling the steel wire, so that the secondary restoration is achieved, and the separation of the broken ends of the bone is further reduced. The screwing effect is achieved through the rotation of the second holding rod 4.
It should be understood that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same, and it is obvious for those skilled in the art that the technical solutions described in the above embodiments can be modified or some technical features can be replaced equivalently as long as there is no structural conflict; and all such modifications and alterations should fall within the scope of the appended claims.
