Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

The polishing device for the medical instrument is mainly applied to polishing of the medical instrument with small size, and not only is fixing difficult, but also scenes with insufficiently polished corners of the instrument are easily generated.

Referring to fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, fig. 6 and fig. 7, a polishing device for medical instruments, including a base plate 1, one side fixedly connected with bracing piece 2 of the outer wall of bottom plate 1 top, the top fixedly connected with supporting ring pad of bracing piece 2, fixedly connected with case 5 of polishing on the top outer wall of supporting ring pad, the inside wall of case 5 of polishing is provided with inner notch 15, it has the delivery hole to open on the bottom inner wall of case 5 to polish, fixedly connected with mount 13 on the inner wall of delivery hole, fixedly connected with motor 11 on the bottom outer wall of mount 13, the one end of motor 11 output shaft is connected with bull stick 4, the top fixedly connected with attach fitting 18 of bull stick 4, swing joint has equidistantly distributed connecting block 19 on the circumference outer wall of attach fitting 18, the equal fixedly connected with movable rod 12 in one side of a plurality of connecting block 19, the one end fixedly connected with screw rod 17 of movable rod 12, threaded connection has ball 14 on the outer wall of screw rod 17, 14 and inner notch 15 looks adaptation, still cup joint has the lantern ring 24 on the outer wall of lantern ring, all be equipped with the mounting rod 25 on the outer wall, the one end of mounting rod is equipped with a plurality of screw rod 22 and uses the fixed plate 17.

Wherein, the rolling ball 14 is made of ceramic material, and the mass of the rolling ball 14 is three times of that of the movable rod 12; the great spin 14 of quality can be fully in rotatory in-process and the bottom inner wall of interior notch 15 contacts, fully promotes to wrap up in the apparatus of holding under the arms in the sand of polishing and turns over and polish, and this scheme is small-size medical instrument, the following to the apparatus of polishing simultaneously.

It should be noted that the rolling ball 14 may be made of a metal material with a relatively heavy weight, but it is required that the metal material does not absorb and sand.

Wherein, a baffle ring 20 is arranged at the joint of the movable rod 12 and the screw 17, and a lantern ring 24 is positioned between the baffle ring 20 and the rolling ball 14; the push collar 24 can be concomitantly moved closer to the outlet opening during the movement of the ball 14 along the screw 17.

In the in-service use process, the polishing sand is placed in the inner groove opening 15, after a to-be-polished small-volume medical instrument is placed in the inner groove opening 15, the arranged rotating rod 4 drives the movable rod 12 and the screw rod 17 which are movably connected to each other to rotate together under the driving action of the motor 11, and in the rolling process of the rolling ball 14, the instrument can be driven to move together with the rolling ball 14 in the inner groove opening 15, so that the rolling polishing sand is pushed to polish the instrument in a matching mode.

Specifically, along with the rolling process of the rolling ball 14, the rolling ball 14 is continuously screwed on the outer wall of the screw rod 17, and then approaches to the position of the guide-out hole, the sleeve ring 24 is pushed to move towards the guide-out hole in the approaching process, so that after the instrument is ground for a certain number of turns, the fixing plate 22 connected to the sleeve ring 24 pushes the instrument into the guide-out hole to be guided out.
