In a first embodiment, as shown in fig. 1-2, a torsion tube structure includes a hollow tube 100 formed by winding at least one strand of wire 110. The hollow tube 100 has good torsional properties and good rigidity, and is suitable for use in medical industries and the like.

The number of wires 110 ranges from 1 to 36. The greater the number of wires 110, the faster the speed of winding into the hollow tube 100.

The wire 110 is made of stainless steel. The stainless steel has low material cost and is easy to produce.

The wire 110 is made of platinum iridium alloy. The platinum iridium alloy can provide good development characteristics.

The wire 110 is made of cobalt-chromium alloy. The cobalt-chromium alloy can provide good mechanical properties.

The cross section of the wire 110 is circular, elliptical or square. Different shapes are selected according to different requirements, so that different mechanical requirements are met.

The wire 110 is coiled around the axis of the wire 110. The wires 110 are spirally wound together, and a gap between adjacent wires 110 is 0.01 to 0.1mm. The gap is different and the performance achieved is different.

In the second embodiment, a steel wire with a diameter adapted to the hollow tube 100 is further disposed in the hollow tube 100. In the process of manufacturing the hollow tube 100, a steel wire is penetrated into the hollow tube 100, and the size and shape of the steel wire are matched with those of the hollow tube 100, so that the rigidity of the hollow tube 100 is improved, and better surface stability is obtained, so that the hollow tube 100 has good processing performance.

The foregoing description of the preferred embodiments of the utility model is not intended to limit the utility model to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the utility model are intended to be included within the scope of the utility model.
