Abstract

The invention relates to a device for dynamically restraining movement of a rod body, in particular to a rod body conveying restraining device. The device comprises a scissor fork mechanism, a restraining piece, a base and a rod body isolation sleeve, the two ends of the scissor fork mechanism are connected to the base, and the scissor fork mechanism can stretch and retract front and back along with the movement of the rod body (relative movement of the base), the restraining piece on the scissor fork mechanism can dynamically restrain the rod body, and the rod body isolation sleeve on the rodbody can achieve dynamic isolation. According to the device, axial movement of the rod body can be effectively guaranteed, the rod body is protected against buckling, force and displacement of the near end can be accurately and effectively transmitted to the far end, the rod body can be conveniently isolated from the conveying restraining device, pollution from the rod body is avoided, the disinfection requirement is reduced, and the rod body is convenient to mount and dismount.

Description

technical field [0001] The invention relates to a device for dynamically constraining the movement of a rod body, in particular to a rod body conveying restraint device, which can be used in the fields of medical equipment, robots and the like. Background technique [0002] The rod body is relatively common, it may be a hard rigid body, it may also be a flexible body, it may have various types of cross-sectional shapes, it may be a solid structure, or it may be a hollow or multi-cavity structure. When the rod body moves axially or rotates around the axis, if the body lacks constraints, the rod body is prone to bending deformation, which in turn affects the movement of the rod body or the transmission of force from the proximal end to the distal end. In the field of medical devices and robots, endoscopes, sheaths, puncture needles and other rod devices are guided by medical images, intervene in the human body and interact with human tissues to perform minimally invasive diagn...
