Abstract

The invention discloses a driving mechanism realizing liner and rotary movement of slender body apparatuses, namely a liner driving structure and a rotary driving structure. The liner driving structure and the rotary driving structure are divided into two parts by using a dotted line frame plane as a division, are in liner arrangement and mounting, and are respectively provided with a respective driving motor; operation of the motors can perform discretionary combination; when the liner driving structure drives the slender body apparatuses to go forward and move backwards, the rotary driving structure can also clamp the slender body apparatuses to make rotary movement; through a structure manner of a gear set in a rotary box body, radial friction required by rotation of the slender body iseffectively provided, and besides, interference to the slender body apparatuses in axial movement is avoided. The driving mechanism is scientific and reasonable in design, simple in structure and convenient to use.

Description

Technical field: [0001] The invention relates to a driving mechanism for realizing the linear and rotary motions of slender instruments, and belongs to the technical field of slender instrument driving mechanisms. Background technique: [0002] Vascular interventional surgery robots need to control the slender body device to perform any combination of forward, backward and rotating movements in practical applications. The existing driving mechanism has a complex structure and is inconvenient to use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a drive mechanism for realizing the linear and rotary motions of slender body instruments. The linear drive structure and the rotary drive structure have their own drive motors respectively, and the operation of the motors can be combined arbitrarily. When the structure drives the slender body device to move forward and backward, the rotating drive structure can also cla...
