Patent ID: 8177555

Claim:
A device for extraction of a dental root, having a pin that can be inserted into the dental root and secured there and having a unit that can be connected to the pin for generating force required for extraction of the root, the pin can be secured on a distal end of the unit by a connecting piece, whereby an impact force that can be transmitted to the pin in a direction of extraction can be generated by the unit, wherein: the pin is a threaded pin having threads at a free end region to enable the pin to be screwed into the dental root; the unit has an elongate housing and a striker that is displaceable in an interior of the housing, the striker being displaced in the extraction direction in the interior of the housing to generate the impact force such that impact of the striker against the housing generates the impact force which is transferred to the pin, impacts of the striker against the housing of the unit are generated mechanically, pneumatically or electromagnetically and triggered manually, the connecting piece is a connecting rod with the pin fastened onto one end region of the connecting rod and which is detachably connectable to the unit at another end region of the connecting rod facing away from the pin, wherein the connecting rod is made of a slightly elastic material, wherein the connecting rod has a small diameter of a few millimeters so that it takes up little space on insertion into the mouth, whereby the pin is screwed into the dental root and then the unit is manually triggered to cause the mechanical, pneumatic or electromagnetic generation of the impact force which in turn causes extraction of the dental root into which the pin is screwed.
