Carriage assembly for controlling a steering wire steering mechanism within a flexible shaft |
摘要 |
A carriage assembly for controlling a steering wire steering mechanism within a flexible shaft, for use in gastrointestinal tract surgery, comprises a plurality of selectably engageable motors, including two drive motors for selectably rotating drive shafts of a surgical attachment, two steering motors mechanically communicating with corresponding pulleys around which are coiled directional steering wires communicating with a flexible shaft to enable the selective direction of the flexible shaft within a spatial plane, wherein within the assembly housing the steering motors travel on a steering motor carriage and the pulleys travel on a pulley carriage which is biased by a spring means away from the interior wall of the housing, which biases the steering wires toward a taut state. The bias can be overcome by a carriage motor mechanically communicating with the pulley carriage to cause the flexible shaft to go limp. Also disclosed are a series of surgical attachments which may be coupled to and utilized in conjunction with the carriage assembly.
