DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-Figure 4In order to solve the problem that the Nice knot needs to be tied with two strands of thread, the current needle can only pull the thread one by one, which is cumbersome, time-consuming and labor-intensive, increases the difficulty of the surgical process, and is not practical enough, the following preferred technical solutions are provided:
[0023] A needle structure that is convenient for completing a Nice knot, comprises a needle body 1, a soft rod assembly 2 is installed on the upper end of the needle body 1, a wire hole assembly 3 is installed on the end of the soft rod assembly 2 away from the needle body 1, the wire hole assembly 3 comprises a wire hole ring A31 installed on the upper end of the soft rod assembly 2, a wire hole ring B32 is arranged on one side of the wire hole ring A31, an outer shaft body 33 is arranged on the lower end of the wire hole ring B32, the inner wall of the outer shaft body 33 is rotatably connected to an inner shaft body 34, the outer wall of the inner shaft body 34 is sleeved with a reset torsion spring 35, one end of the reset torsion spring 35 is fixedly connected to a middle connecting rod 36, and the end of the middle connecting rod 36 away from the reset torsion spring 35 is fixedly connected to the wire hole ring B32.
[0024] The outer shaft body 33 is fixedly connected to the upper wall of the soft rod assembly 2, the inner shaft body 34 is rotatably connected to the upper wall of the soft rod assembly 2, the upper wall of the wire hole ring B32 is in contact with the upper wall of the wire hole ring A31, and the reset torsion spring 35 is in a taut state at this time, and there are two groups of wire hole rings B32, and the two groups of wire hole rings B32 are symmetrically distributed about the center of the wire hole ring A31.
[0025] The soft rod assembly 2 includes a lower connecting block 21 fixedly connected to the needle body 1 at one end, and an upper connecting block 22 fixedly connected to the outer shaft body 33 at one end. An elastic soft rod 23 is fixedly connected between the lower connecting block 21 and the upper connecting block 22. The elastic soft rod 23 is a component made of beryllium bronze.
[0026] Specifically, when threading, two strands of wire can be inserted through the cooperation of the wire hole ring A31 and the wire hole ring B32, so that the double strands of wire can be pulled out at one time, which is convenient for directly making a Nice knot without pulling the wires one by one. The operation is convenient and solves the problem of needing to knot the double strands of wire when completing the Nice knot. The current needles can only pull the wires one by one, which is cumbersome, time-consuming and labor-intensive to operate, increases the difficulty of the surgical process, and is not practical enough.
[0027] After the wire is passed through, the wire hole ring B32 can be pulled to one side so that the upper wall of the wire hole ring B32 no longer fits the wire hole ring A31. At this time, the rotation of the inner shaft body 34 will further compress the reset torsion spring 35. Then the wire passes between the wire hole ring A31 and the wire hole ring B32, and then the wire hole ring B32 is loosened. The wire hole ring B32 will compress the wire under the action of the reset torsion spring 35, which not only facilitates hanging the wire, but also ensures the stability after threading, with significant effect.
[0028] Beryllium bronze has strong elasticity, so under the organic cooperation of the lower connecting block 21, the upper connecting block 22 and the elastic soft rod 23, the needle can pass through bones at various angles, and has good practicality.
[0029] To sum up: when threading, two strands of wire can be inserted through the cooperation of wire hole ring A31 and wire hole ring B32, so that the double strands of wire can be pulled out at one time, which is convenient for directly making a Nice knot without pulling the wires one by one. After passing the wire, the wire hole ring B32 can be pulled to one side so that the upper wall of the wire hole ring B32 is no longer in contact with the wire hole ring A31. At this time, the rotation of the inner shaft body 34 will further compress the reset torsion spring 35, and then the wire passes between the wire hole ring A31 and the wire hole ring B32, and then the wire hole ring B32 is loosened. The wire hole ring B32 will compress the wire under the action of the reset torsion spring 35, which is not only convenient for hanging the wire, but also ensures the stability after threading. The beryllium bronze material has strong elasticity, so under the organic cooperation of the lower connecting block 21, the upper connecting block 22 and the elastic soft rod 23, the needle can pass through bones at various angles.
