A bone harvesting device includes a main body having an internal cavity and a suction port adapted to be coupled to a suction source. The device further includes an outer tube () having an interior surface, an exterior surface, a proximal end and a distal end, the proximal end of the outer tube being coupleable to the main body, an inner tube having an interior surface, an exterior surface, a proximal end and a distal end, the inner tube being in fluid communication with the internal cavity and at least partially disposed within the outer tube such that a venting channel is defined between at least a portion of the inner tube and at least a portion of the outer tube.

Bone material harvesting device

Device and a method for positioning and monitoring the rotary orientation of extremity bone fragments when implanting an intramedullary implant, and in particular to a device and a method for monitoring the rotary orientation of extremity bone fragments of the leg when implanting an intramedullary nail by using a monitoring of locking means of the intramedullary nail which so as to improve the accuracy of the orientation of extremity bone fragments.

Devices and methods for monitoring the rotational orientation of bone fragments

An implant for osteosynthesis, for example a bone nail, has an implant body which has at least one bore with a threaded portion and a bone screw which engages the thread when it is threaded into a bone for the fixation of the implant body. The threaded bore has an annular groove the diameter of which is larger than the thread outer diameter, and which receives a ring of a deformable material with an inner diameter which is smaller than the outer diameter of the thread of the bone screw so that the ring extends partially into the bore.

Implant for osteosynthesis

A screwdriver for bone screws, especially for compression screws and locking screws, has a handle and shaft extending out centrally from the handle. The shaft has a screwdriving tool on its free end. The shaft, includes a flexible shaft portion, wherein the shaft has two rigid, solid portions on both sides of the flexible portion. The flexible shaft portion has a flexible element for the transmission of a torque, and at least the flexible shaft portion is surrounded by an elastic protection hose or a rubber or plastic elastomeric tubular cover.
