Abstract:
An exchangeable tool assembly for an endoscopic treatment device, comprising:a rotating tool adapted to contact and treat a surface; a coupling element for coupling said tool assembly to a motor of a treatment device; a flexible shaft having a distal end and a proximal end, said distal end being connected to said rotating tool and said proximal end being connected to said coupling element, said flexible shaft transmitting a rotary movement of said motor to said rotating tool in order to cause said rotating tool to rotate, said flexible shaft being connected to said rotating tool and said coupling element such that said flexible shaft and said rotating tool and said coupling element form a jointly exchangeable integral unit; and a locking mechanism for releasably holding said tool assembly at said treatment device, said locking mechanism comprising a locking element arranged at said rotating tool and a locking member arranged at said treatment device, which is engageable with said locking element to releasably hold said jointly exchangeable unit formed by said rotating tool and said flexible shaft and said coupling element, wherein said rotating tool, said flexible shaft and said coupling element are adapted to be withdrawn as an integral unit when the locking member arranged at said treatment device is disengaged from the locking element arranged at said rotating tool.
