Abstract:
1. An injection device, comprising: a housing having a distal end and a proximal end, the housing configured to releasably receive a solution cartridge containing a solution; a solution dispensing mechanism configured to dispense solution from the solution cartridge; a tool connecting portion configured to be connected with a tool; a motor driven rotation device configured to rotate the tool about an axis; wherein the solution dispensing mechanism comprises a rack having teeth and a manually operated actuator, said manually operated actuator having a starting position and being connected to an engagement device engagable with the teeth of the rack, wherein the manually operated actuator and the engagement device are both pivotally supported by the injection device, such that when the manually operated actuator is pivotally moved towards the housing of the injection device to leave its starting position, the engagement device engages the teeth of the rack and moves the rack towards the solution cartridge, wherein the solution dispensing mechanism and the motor driven rotation device are configured such that actuation of a motor to drive the motor driven rotation device does not actuate the rack of the solution dispensing mechanism, wherein the rack is at least partially covered by a cover which has markings to indicate an amount of solution being delivered, wherein the rack comprises an element extending substantially perpendicular from the rack through the cover which indicates together with the markings of the cover the amount of solution being delivered.
