Exchangeable tool assembly for an endoscopic treatment device and such treatment device
First Claim
1. 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and said coupling element, wherein said rotating tool, said flexible shaft and said coupling element are adapted to be withdrawn as an integral unit when the locking member arranged at said treatment device is disengaged from the locking element arranged at said rotating tool.

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to releasably hold said unit formed by said tool unit and said flexible shaft at the treatment device, which can be withdrawn as a whole after this engagement of said locking member from said locking element.

9. 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, said flexible shaft being connected to said rotating tool such that said flexible shaft and said rotating tool form a jointly exchangeable unit; and
