1. A medical instrument for removing tissue comprising: an elongate body,a tool shaft coupled to a distal end of said elongate body, said tool shaft being rotatable,a motorized drive for rotating said tool shaft, said motorized drive being housed in said elongate body and connected to a power connection,a connection being coupled to a proximate end of said elongate body, said connection being configured for supplying a vacuum to the inside of said tool shaft; said tool shaft being configured for removing said tissue by suction;a handle projecting laterally from said elongate body, when mounted at said elongate body said handle being a separable component and not a part of said elongate body,wherein said handle is fastened in a detachable manner to said body, andwherein said elongate body is shaped in that it can be ergonomically gripped in the manner of a rod when said handle is detached, said tool shaft can be rotated by said motorized drive when said handle is detached. 2. The medical instrument of claim 1, wherein said handle can be fixed to said body at different positions along a longitudinal axis of said body. 3. The medical instrument of claim 2, wherein said handle can be fixed in a stepless manner at different positions along said longitudinal axis of said body. 4. The medical instrument of claim 2, wherein said handle has a locking system, by way of which it can be locked in a position along said longitudinal axis of said body. 5. The medical instrument of claim 1, wherein said handle has a recess for accommodating said body, wherein at least two substantially parallel bars which are located opposite one another are provided in an upper region of said recess and, in a state in which said handle is connected to said medical instrument, engage in corresponding grooves that are arranged on said body. 6. The medical instrument of claim 5, wherein said handle further has at least one adjustable finger, which, from a position in which a tip of said finger is recessed in an inner surface of said recess, can be braced against said body in order to lock said handle to said body. 7. The medical instrument of claim 1, wherein said handle projects from said body at an angle other than 90°. 8. The medical instrument of claim 7, wherein said handle is designed in such a way that it can be attached to said body in a manner angled in either a distal direction or a proximal direction. 9. A handle for use with a medical instrument comprising: on its upper side a recess for accommodating the body of said medical instrument, wherein at least two substantially parallel bars which are located opposite one another are provided in an upper region of the recess and, in a state in which said handle is connected to said medical instrument, engage in corresponding grooves that are arranged on said body of said medical instrument;wherein said handle further has at least one adjustable finger, which, from a position in which a tip of said finger is recessed in an inner surface of said recess, is movable in the direction of an interior of said recess, andwherein a rotary knob is connected to said adjustable finger, a rotation of said rotary knob moves said finger in said direction of said interior of said recess, said rotation of said rotary knob allows the control of a force exerted by said finger onto said body of said medical instrument. 10. The handle of claim 9, wherein between a longitudinal axis of said recess and a longitudinal axis of said handle there is an angle other than 90°. 11. The handle of claim 10, wherein said handle can be attached to said body in a manner angled in either a distal direction or a proximal direction.
