Technical Field

The invention relates to a winding device, in particular to a medical shape memory alloy winding machine, and specifically relates to a medical embolism spring multi-degree-of-freedom automatic winding machine.

Background

Medical embolic coils are widely used for treating intracranial aneurysms and the like, with the most important component being a balloon-shaped coil because of its relatively small size, flexibility and complex shape. The traditional processing mode is manual operation, operators can go on duty only through long-time training and practice, and the winding space structure is complex, and the path is tortuous. The error is easy to occur in the actual operation process, and the whole waste can be caused. And because the spring ring is softer, the quality is influenced because the spring ring is unscrewed because of misoperation in the operation process.

Disclosure of Invention

The invention aims to design a medical embolism spring multi-degree-of-freedom automatic winding machine capable of automatically completing a complex winding process, aiming at the problems of high difficulty and low yield of manual winding of the existing spherical embolism spring.

The technical scheme of the invention is as follows:

the utility model provides a medical embolism spring multi freedom automatic coil winding machine, which is characterized in that it includes base 1, the one end and the base 1 of first linking arm 2 are fixed continuous, the other end and the first motor 3 of first linking arm 2 are fixed continuous, the axle play axle of first motor 3 is fixed continuous with the one end of second linking arm 4, the other end and the second motor 5 of second linking arm 4 are fixed continuous, the output shaft of second motor 5 is fixed continuous with the one end of third linking arm 6, the other end and the third motor 7 of third linking arm 6 are fixed continuous, the output shaft of third motor 7 is fixed continuous with the one end of fourth linking arm 8, the other end of fourth linking arm is fixed on fourth motor 9, install design mould 10 on the output shaft of fourth motor 9.

The first motor 3, the second motor 5, the third motor 7 and the fourth motor 9 are all stepping motors.

The shaping mold 10 is a four-bar, six-bar or eight-bar shaping mold, the four-bar six-bar or eight-bar shaping mold is composed of a main bar connected with an output shaft of a fourth motor and six or eight auxiliary bars 102 uniformly arranged around the main bar 101, and an included angle between the axis of each auxiliary bar 102 and the axis of the main bar 101 is 70-75 degrees.

The first connecting arm 2, the second connecting arm 4, the third connecting arm 6 and the fourth connecting arm 8 are annularly fixed on the corresponding motor with one end connected with the corresponding motor, a conducting ring for supplying power and controlling wiring of the corresponding motor is arranged in the annular end, and power supply and communication are carried out through a sliding ring so as to prevent the rotation of the motor from causing winding interference of cables.

The invention has the beneficial effects that:

the invention can avoid human error and improve the qualification rate and the production efficiency. The winding path of the invention can be strictly carried out according to the program, and the winding is accurate and the stress is uniform and consistent. The spring ring made by winding manually not only has a shape closer to the design, but also reduces the hand pollution in the process of manual winding.

The invention is more convenient for designing and manufacturing more complicated shapes. More material (platinum-tungsten alloy) is saved, and cost and time are reduced.
