Abstract

An exchangeable tool assembly is provided for an endoscopic treatment device, comprising a flexible shaft connected at its distal end to a tool unit and at its proximal end to a coupling element for coupling the tool assembly to a motor of the treatment device. The flexible shaft transmits a rotary movement of the motor to the tool unit. The flexible shaft is connected to said tool unit such that said flexible shaft and said tool unit form a jointly exchangeable unit. Further, a locking mechanism for releasably holding said tool assembly at said treatment device comprises a locking element arranged at said tool unit and a locking member arranged at said treatment device which is engageable in said locking member to releasably hold said unit formed by said tool unit and said flexible shaft at the treatment device, which can be withdrawn as a whole after this engagement of said locking member from said locking element.
