MECHANISM FOR RECIPROCATING LINEAR MOTION OF A MEDICAL DEVICE |
| 摘要 |
A mechanism for reciprocating linear motion of a medical device comprises a body, wherein are mounted a rotatable shaft driven with a drive unit and a guide with a slidably platform mounted thereon. The rotatable shaft has a smooth external surface and is connected with a shaft of the drive unit by means of an intermediate mechanism comprising at least two unidirectional clutches mounted on the smooth rotatably shaft in opposite directions. The platform is integrated with a transport mechanism which is mounted on the rotatable shaft and comprises rolling elements so arranged that points of contact of said rolling elements with the smooth surface of the shaft determine a helix. |

1. Reciprocating linear motion mechanism of a medical device, comprising a body, wherein are mounted a rotatable shaft driven with a drive unit and a guide with a slidably platform mounted thereon, characterised in that the rotatably shaft has a smooth external surface and is connected with a shaft of the drive unit by means of an intermediate mechanism comprising at least two unidirectional clutches mounted on the smooth rotatably shaft in opposite directions, and the platform is integrated with a transport mechanism which is mounted on the rotatable shaft and comprises rolling elements so arranged that points of contact of said rolling elements with the smooth surface of the shaft determine a helix. |
