Abstract
The invention concerns a cassette comprising a sterile barrier. The sterile barrier comprises attachment brackets each attached to a drive member for driving an elongate flexible medical device, and flexible portions between two adjacent attachment brackets. The flexible portions are connected to the attachment brackets. The drive surfaces of the attachment brackets come into contact with the elongate flexible medical device.
Claims25
A robotic drive module for an elongate flexible medical device, the robotic drive module comprising:
- a base,
- a pair of drive members each having a drive surface, the pair of drive members being placeable in a drive configuration in which the drive surfaces of the drive members of the pair of drive members engage with the elongate flexible medical device to be driven, and are arranged on either side thereof, the pair of drive members being movably mounted relative to the base along one degree of freedom between a first and second position,
- a control member suitable for controlling a movement relative to the base of the drive members of the pair of drive members in the drive configuration from the first to the second position, thus driving the elongate flexible medical device relative to the base, and
- a disposable consumable sterile barrier comprising an attachment bracket for each drive member, and a flexible portion between adjacent attachment brackets, the flexible portion being connected to the attachment brackets, each drive member being attached to an attachment bracket, drive surfaces of the attachment brackets being intended to come into contact with the elongate flexible medical device,
- wherein the pair of drive members are placeable alternately in the drive configuration and in a free configuration in which the drive surfaces of the drive members of the pair of drive members is not engaged with the elongate flexible medical device,
- wherein the control member is suitable for controlling, in a repeated cyclical manner, the movement of the drive members relative to the base, in the drive configuration, from the first to the second position, and a movement relative to the base of the drive members of the pair of drive members, in free configuration, from the second to the first position without driving the elongate flexible medical device relative to the base,
- wherein each attachment bracket is assembled on the drive member by means of frangible zones connecting the drive surface, in contact with the elongate flexible medical device, to an assembly portion on the drive member.
