Definitions
- Screw for insertion into a bone and unscrewing tool therefor
- the invention relates to a screw for insertion into a bone, in particular for fastening plates that support the fixing of bone parts, with a screw body that has a threaded section and an indirectly or directly adjoining head, on which a device for screwing the screw body into the bones is provided.
- the invention further relates to a boring tool for such a screw or its screw body.
- Bone screws are very small, with a head size that is usually less than 5 mm
- a flat slot or a cross slot for screwing the screw into the bone.
- Such screws are mainly used to fasten plates that support the fixation of bone parts.
- the very flat design means that the slot or the cross slot for screwing in or out the screw can only be very flat. Not only does this mean that the tool for manipulating the screw is very difficult to apply, there is also a risk that the blade of the tool will slip and cause damage.
- the screw according to the invention is characterized in that the device for screwing in the screw body is a shaft formed in one piece with the head, at least one predetermined breaking point being formed in the connection area between the head and the shaft. Screw body and insertion tool are thus initially available as one unit. This unit can be screwed into the bone using a suitable rotary drive with low speeds. After the screw-in depth has been reached, the torque acting on the predetermined breaking point increases so much that the screw body breaks off the shaft and is thus placed in the bone.
- the at least one predetermined breaking point therefore advantageously defines a surface which is dimensioned in accordance with a desired maximum tightening torque of the screw.
- the size of such an area can be determined by experiments, possibly also depending on the choice of material.
- the screw body has a web on the head to which the shaft is connected.
- the predetermined breaking point is located on the side of the web facing the shaft.
- Such a web which is expediently designed as a central web, can be produced by immersing a milling cutter on two sides, offset from the central axis of the screw body, which leaves the desired web straight.
- the unscrewing tool for such a screw or its screw body is then characterized in that a slot is provided at a free end of the unscrewing tool body, which slot is dimensioned such that it engages the head of the screw body via a coupling section, for example the web.
- the boring tool has a shape in the area of the slot in such a way that lugs defining the slot lie snugly in notches which are formed on both sides of the web in the head of the screw body.
- Figure 1 is a side view of a screw for insertion into a bone according to an embodiment of the present invention
- FIG. 2 shows a sectional view through the screw in the area of her head
- Figure 3 is a plan view of the head, with the shaft broken away;
- Figure 4 is a side view, partially in longitudinal section, of the boring tool for a screw or its screw body according to the invention.
- FIG. 5 shows a side view of the boring tool rotated by 90 ° in relation to FIG. 4, again partially cut away.
- FIG. 1 shows a side view of a screw according to the invention for insertion into a bone.
- the screw consists of a screw body 10 and a screw-in tool 20, which are integrally formed with one another, a predetermined breaking point 28 being defined in the connection area between screw body 10 and screw-in tool 20.
- the screw body 10 consists in the usual way of a threaded section 12 and a head 14 directly or indirectly adjoining it.
- the screwing tool 20 is formed from an elongated shaft 22 which extends in the direction of the head 14 of the screw body 10 over a certain section 24 rejuvenated. At the end of shaft 22 opposite section 24, a coupling part 26 is provided for an angle piece or the like.
- Figure 2 shows a longitudinal sectional view of the head 14 of the screw body 10.
- the central axis and notches 18 set apart from this, for example by means of a corresponding milling tool, so that a web 16 remains within the head 14, on its exposed surface, as can be seen directly in FIG. 3, the predetermined breaking point 28 is provided.
- the predetermined breaking point is shown in FIG. 3 as a circular surface, but other surface shapes and thus surface sizes are also possible, so that the desired maximum tightening torque for the screw in the bone can be determined via the dimension of this surface.
- the screwing tool 20 breaks off at the tapered section 24 or at the predetermined breaking point 28 from the web 16 of the screw body 10 .
- an unscrewing tool is expediently used, as is shown in partial side views in FIGS. 4 and 5. It is essential for the boring tool 30 that a slot 34 is formed at the free end of the boring tool body 32, which can be seen particularly well in the partially cut-away area of FIG. 5, the slot 34 being dimensioned such that it overlaps engages the web 16 in the head 14 of the screw body 10. To a fuller. To ensure the fit of the boring tool 30 in the head 14, lugs 36 are formed on both sides of the slot so that they lie essentially in a positive manner in the notches 18 in the head 14 of the screw body 10.
- the unscrewing tool 30, like the screwing-in tool 20, can be provided with a coupling part for an angle piece.
