Embodiment Construction

[0077] figure 1 Is a schematic illustration of a first embodiment of a medical tool 10 of the present invention comprising a base 12 and a needle 14 . A first end of the needle 14 is disposed on and connected to the base 12 . On the end of the needle 14 which is not connected to the base 12 there is a drilling section 16 . The drilling section 16 tapers toward the free end of the needle 14 and has at least one groove on its surface, wherein the groove winds around the drilling section 16 helically.

[0078] Following the drilling section 16 and between the drilling section 16 and the base 12 is a retention section 18 . The diameter of the retaining section 18 at its base element 20 is at least approximately equal to the diameter of the drilling section 16 . On the base element 20 of the retaining section 18 are provided retaining elements 22 in the form of barbs. The retaining element 22 is connected materially to the base 20 of the retaining section 18 . In this case, th...

Abstract

The invention relates to a medical tool and to a method for using the medical tool for removing tooth fragments, in particular tooth roots and/or remainders of tooth roots, from a tooth socket or an alveole in the region of the jaw.

Description

technical field [0001] The present invention relates to a medical tool for removing tooth fragments, in particular tooth roots and / or root remnants, from tooth sockets or tooth sockets located in the area of ​​the jaw. Background technique [0002] During tooth extraction, especially when it is necessary to extract a tooth that has been severely damaged, the tooth to be extracted may fracture and / or crumble and fragments of the tooth, especially the root or root remnants, may remain in the socket or in the alveolar. In order to remove this tooth fragment from the socket, a relatively complex multi-step procedure with the aid of special instruments has always been required until now. The complexity of this surgical procedure can vary depending on the size and stability of the tooth fragments left in the socket, and on the depth and shape of the socket. [0003] When carrying out such extraction operations on tooth fragments, in particular roots or root remnants, the solutio...
