Embodiment Construction

[0060] Such as figure 1 and 2 , an extraction device for extracting a bone core. Such an extraction device may be used in the field of orthopedic surgery in general, and even more particularly in the field of dentistry for fitting endosseous implants. The extraction device comprises a cylindrical tool 1 generally comprising a wall of rotation defining an axial hollow 2 for receiving the bone core to be extracted. Said axial hollowing out leads to its distal end in order to provide passage with the extracted core, the cylindrical wall of the tool being equipped at the distal end with teeth for perforating the bone material 7 along a circular cutting line. Said teeth are more particularly formed by serrations or the like on the distal side of the cylindrical wall of the tool, said serrations or the like providing a circular cutting line defining the periphery of the extracted core, said The core is accommodated inside the axial hollow 2 of the tool 1 . The benefit of extract...

Abstract

The present invention relates to an extracting device for extracting bone core (20). The extracting device comprises a tubular tool (1) and a grasping tail (3) for rotating and driving the tool (1) through one apparatus. The devices for guiding the tool (1) comprise a rod (4) exposed from the tool (1). The rod (4) is installed with centralizing devices (2, 11; 9, 10) on the extracting device. The devices for guiding the tool (1) include a drill (19, 25). The drill (15) can install a front opening (6) in the bone material before the tool (1) contacts the bone material (7). The front opening (6) forms a channel for receiving the exposed end of rod (4). The exposed end of rod (4) forms a guiding finger-shaped object (5) which is installed with a pin mode. The pin can be guided to one front opening (6) according to the invention.

Description

technical field [0001] The present invention relates to the field of surgical instruments, and more particularly to an extracting device for extracting tightly bound bone cores. The invention is intended for an extraction device equipped with means to facilitate the use of the extraction device for the convenience of the physician in relation to the guidance of the tubular cutting tool contained in said extraction device and in relation to the removal of the bone core extracted by this extraction device work. Background technique [0002] Extraction devices for extracting bone cores are known in the field of surgery, for example in dental surgery. Extraction devices of the first type are provided for extracting pulverulent bone material and / or a comminuted product. Such extraction devices allow easy use of the extracted bone material, but the consistency of said material is not suitable for graft applications and / or bone filling. A second type of extraction device is prov...
