Quick-connection type magnetic transmission apparatus for use in medical interventional instrument

A quick-connection type magnetic transmission apparatus, comprising a drive-side housing and a driven-side housing, the driven-side housing including a driven-side outer shell and a driven-side inner shell, wherein the drive-side housing and the driven-side housing are coaxially arranged and are connected in a nested mode;

• a magnetic coupling structure, a magnetic coupling and coaxial guiding mechanism, and an integral coaxial guiding mechanism are sequentially comprised from inside to outside;
• the magnetic coupling structure consists of a magnetic transmission drive end, a magnetic transmission driven end and a quick-connection separation sleeve;
• the magnetic coupling and coaxial guiding mechanism consists of a magnetic coupling and guiding sleeve and a magnetic coupling and guiding groove;
• and the integral coaxial guiding mechanism consists of a coaxial guiding sleeve, a coaxial guiding groove and a coaxial locking structure;
• the magnetic transmission driven end comprises a driven rotor spacing sleeve;
• the coaxial guiding groove consists of an annular space between the inner wall of the driven-side outer shell and the outer wall of the driven-side inner shell;
• the magnetic coupling and guiding groove consists of a space between the inner wall of the driven-side inner shell and the outer wall of the driven rotor spacing sleeve;
• the inner wall surface of the driven-side inner shell is tightly fitted with the outer wall surface of the magnetic coupling and guiding sleeve;
• and the magnetic transmission drive end is provided between the outer wall surface of the driven rotor spacing sleeve and the inner wall surface of the magnetic coupling and guiding sleeve;
• the coaxial locking structure is a key groove provided on the drive-side housing and the driven-side housing and cooperating with each other.
