Cleaning tool of ESD electrotome with injection function

The invention discloses a cleaning tool of an ESD electrotome with an injection function. The cleaning tool comprises an inner needle, a sleeve and a reset spring, wherein the sleeve is in sleeving on the outer side of the inner needle; a needle tip is arranged at the front end of the inner needle, a driving rod is arranged at the rear part, a clamping ring is arranged in the middle of the driving rod, a pressing part is arranged at the tail end, and a transition part is arranged between the tail end of the needle tip and the driving rod; the front end of the sleeve is provided with an ESD electrotome insertion groove and a containing cavity for containing the inner needle; a needle hole is arranged on the middle position of the bottom of the ESD electrotome insertion groove; the inner needle is arranged in the containing cavity; the clamping ring slides in the containing cavity and achieves a limiting effect; and the reset spring pushes the inner needle to move to the direction away from the ESD electrotome insertion groove. The cleaning tool is simple in operation, and surgery time can be greatly saved. When an injection hole dredging operation is carried out, the electrotome and the injection hole are effectively protected and prevented from being damaged. In an electrotome dredging process, the inner needle is located in the sleeve in the whole process, medical staff can not be punctured, and secondary infection is avoided.
