This invention relates to medicine and can be used in restorative traumatology.

The purpose of the invention is to reduce trauma and labor while forming channels in the bone.

Fig. 1 shows a device for forming bone channels, a general view; figure 2 - section aa in figure 1.

The device comprises a working part in the form of a spear-shaped tip 1 with pointed edges 2 and 3, a T-shaped slot 4 and a rod 5,

The device works as follows.

The device is fixed in the head of an electric or mechanical drill. Rotational movements form the bone canal. At the same time, the chips are not removed from the channel, but are rubbed along its walls, slightly pressing them. This is ensured by positioning the pointed edges 2 and 3 on tip 1 and directing them in one direction. In this connection, one face 2 of the tip carries out the formation of the canal, and the other face 3 forms bone chips that are evenly rubbing along the walls of the canal, thereby reducing the bleeding from the bone. After windows 417 | -y F1 / g.2

The bone canal formation tubes are removed by the handle, thereby opening up the L-shape to slot 4. A plastic material is inserted into the latter, and the device along with the plastic material is pulled through the channel. This becomes possible due to that. that the diameter of the channel is twice the diameter of the sewing. The plastic material in the channel is not impaired; there is practically no bleeding from the channel.

Claims (1)

Claims An apparatus for forming bone channels for carrying out ligatures, comprising a rod with two working ends, one of which is pointed, and the second has an opening for a ligature, characterized in that, in order to reduce the trauma and labor-intensiveness of the operation, the pointed working part is made as a rhombic tip with two faces, the cutting edges of which are directed to one side, and the tip width is twice the diameter of the rod, the other working part is made in the form of a parallelepiped, the width of which It exceeds the diameter of the rod by 1/3, and the thickness is less than the diameter by half, and the opening for the ligature is made in the form of a T-shaped slot.
