[0004] However, the rotating speed of the flexible shaft used in the field of automobile manufacturing is relatively low. When the torque applied to one end of the flexible shaft is large and the corresponding equipment is driven by the flexible shaft to rotate at a high speed, the flexible shaft itself is prone to occur to a greater extent. deformation of

The invention provides a flexible shaft and a manufacturing method therefor, and a surgical operating system. The flexible shaft comprises a shaft body and a hose, wherein the shaft body is mounted in the hose; the shaft body comprises a tensile shaft core and at least two torsion layers which are arranged on the tensile shaft core layer by layer in a coating manner; each torsion layer is formed by helically winding the tensile shaft core with metal wires; the winding directions of the metal wires in the adjacent two torsion layers are opposite, and the adjacent two torsion layers are in contact; and the two ends of the shaft body are connected with an external power system and an external power switching mechanism respectively, so that the shaft body can rotate in the hose under the rotary power supplied by the external power system, and can drive the external power mechanism to rotate. By adoption of the technical scheme, the deformation degree of the flexible shaft can be lowered.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a flexible shaft, a manufacturing method thereof, and a surgical operating system. Background technique [0002] The flexible shaft is a torque transmission mechanism, the shaft body can be bent to a certain extent, and the torque provided by the power system to one end of the flexible shaft can be transmitted to the equipment connected to the other end in the case of bending, and the equipment can be A specific movement occurs according to the torque force it transmits. [0003] At present, the flexible shaft is mainly used in the field of automobile manufacturing. One end is connected to the gearbox of the automobile, and the other end is connected to the odometer in the automobile. The shaft body is a steel wire core, and the outer cover is a spiral hose. Internal rotation occurs. [0004] However, the rotation speed of the flexible shaft used in the field of aut...
