Each of the screws has a head 5 with a receiving opening for receiving a rod 6 on. With the help of a mother 7 the rod is firmly connected to the head. How out 1 is apparent in the part 1 a third screw 8th screwed, which is designed exactly like the first two screws and a second rod 9 in her head.
The second staff 9 is about a connecting element 10 with the first staff 6 connected. This establishes additional stabilization.
In the above embodiment, the two parts to be joined 1 and 2 Long bone parts. In the same way, there is an application of at least two rods with corresponding screws for receiving the same in spinal surgery, such as a fixator internally, as he, for example, from DE 38 23 737 A1 is known.
The connecting element 10 points in the in 2 shown embodiment, a shaft 11 with a first part 12 at one end and a second part 13 at the other end.
The second part 13 two comprises a U-shaped channel 14 limiting thighs 15 . 16 , The two thighs 15 . 16 have outside a cylindrical shape and have at their free ends an external thread 17 , The U-shaped channel 14 has a diameter substantially equal to or slightly larger than the diameter of a male rod 18 is and is just so big that the staff 18 in the U-shaped channel 14 insertable and guided by this in a lateral direction. Further, a mother 19 provided, which is equipped with its internal thread so that it with the external thread 17 works together. The thread 17 is formed so that the distance from the thread to the bottom of the U-shaped channel 14 smaller than the diameter of the rod 18 so that in the U-shaped channel 14 pickled bar 18 by screwing the nut 19 can be fixed.
How out 2 it can be seen points the other end of the shaft 11 a head having a spherical section 21 on. The first part 12 has a cylindrically shaped socket 20 on, whose diameter is substantially equal to or a little larger than the diameter of the head 21 is and is dimensioned so that the head is inserted into the bore and guided by this.
In the embodiment shown, the bore 22 a reason 23 which is spherical, with its radius equal to the radius of the head 21 , Like from the 2 and 3 can be seen, is the shaft 11 formed detachable via a screw from the spherical head.
One of the two parts has a threaded hole, while the other part has a screw part which can be screwed into the threaded bore. This connection is schematic through the junction 24 indicated. The threaded hole can also be in the head 21 be provided directly, and the shaft 11 then has at its end facing the head a correspondingly formed Schraubansatz which can be brought into engagement with the threaded bore for screwing the two parts together.
In the in 2 the embodiment shown is initially the shaft 11 from the head 21 unscrewed, so that the head 21 from the free end of the hole 22 in this position can be inserted into the position shown. It then becomes the shaft 11 screwed so that the connection shown in the figure is made.
As 2 further indicates, borders on the reason 23 a second hole 25 on, which is funnel-shaped, so that the shaft 11 around a solid angle relative to the socket 20 is pivotable.
After the inserted head 21 gets into the hole 22 a pressure element 26 used, which is spherically formed on its head-facing side with a radius equal to the radius of the head 21 equivalent. On his head 21 opposite side, the pressure element has a cylindrical surface 27 on, wherein the diameter of this cylinder equal to the diameter of the male rod 28 is, so the staff 28 , in the recess 27 can be inserted. How out 2 it can be seen, the recess is further formed so that a to the bore 22 coaxial, U-shaped channel 31 with these limiting thighs 29 . 30 is formed. The two thighs 29 . 30 show as the second part 13 an external thread adjacent to their free ends 32 which goes so far to the other end of the socket 20 out that its distance from the bottom of the cylindrical recess is smaller than the diameter of the rod 28 , Further, a mother 33 provided, the internal thread of the external thread 32 equivalent.
In operation, the staff is first 18 in the monoaxially acting second part 13 or in its U-shaped channel 14 used. Then the rod with the help of the mother 19 fixed. Subsequently, the version 20 aligned so that they are the second rod 28 absorbs. After insertion of the rod 28 becomes the mother 33 screwed. This not only fixes the rod 28 but exercises over the staff 28 and the pressure element 26 even such a pressure on the head 21 out that this is stabilized in its axial position.
At the in 3 embodiment shown, the version is correct 20 , the pressure element 26 , the head 21 , the rod 28 and the mother 33 in full detail with the first part 12 in 2 match. The embodiment differs only in that the second part is not formed as a monoaxial connection but as a likewise polyaxial connection. This second part 12 ' is to the first part 12 formed mirror-symmetrical. All parts of the socket, head, pressure element, rod and nut are in line with the corresponding parts of the first part 12 match. For mounting is the shaft 11 as in the previously described embodiment by a screw connection along the line 24 solvable. After inserting the heads 21 become the two parts of the shaft 11 firmly connected.
In operation, the connection is made as before on the basis of the first part 12 described, with the version prior to fixing each on the is oriented towards the rod and then inserted the rod and fixed on the mother. By exerting the pressure of the nut on the rod and the pressure element then the head is finally fixed.
In a modified embodiment, not shown, the version 20 or the second part 13 adjacent to each other at its free end still have an internal thread into which an inner screw can be screwed to achieve in this way in a conventional manner blocking the screw.
In the embodiments described above, the head is 21 each inserted from the free end of the U-shaped recess forth. In a modified embodiment, the bore 22 extend through the entire frame. The head is then from the thighs facing away from the end of the bore 22 inserted and held with a locking ring or snap ring to be mounted in the bore. It is crucial that the free edge of the shaft 11 facing the head surrounds, is widened conically, to allow a polyaxial movement between the socket and the head or shaft.
In the 4 embodiment shown is true with regard to shaft 11 head 21 , Rod 18 respectively. 28 and mother 19 respectively. 33 completely with the in 3 match described embodiment. The version is different 34 , This has a first end 35 and a second end opposite this 36 on. It is one to the axis of symmetry 37 the socket coaxial bore 38 intended. Further, one is from the first end 35 outgoing U-shaped recess 39 present, which is transverse to the axis of symmetry 39 extends. The U-shaped recess is made up of two legs 40 . 41 limited. Adjacent to the first end 35 show the two thighs 40 . 41 an external thread 42 on. The diameter of the U-shaped recess 39 is equal to or slightly larger than the diameter of the rod 18 respectively. 28 and just so large that the rod is insertable into the recess and is guided laterally from the sides of the U-shaped recess. The external thread 42 is so far as the base of the U-shaped recess formed as in the embodiments described above, that the distance to the U-shaped base is smaller than the diameter of the male rod. Further, as in the embodiment described above, a nut 33 provided with the external thread 42 interacts.
Unlike the previously described embodiments, the cylindrical portion extends 43 the coaxial bore up to a predetermined distance to the second end 36 and is from there to the second end 36 tapered conically with a cone angle. Furthermore, a pressure element 44 provided, its outer surface in a head 21 laterally encompassing area 45 against the second end 36 is conical, wherein the cone angle corresponds to that of the tapered portion of the bore. The tapered area faces the second end 36 directed towards this and open towards the end slit 46 on. By adapting the conical surfaces between bore 38 and pressure element 44 follows fully retracted state self-locking. The pressure element has in the from EP 0 732 081 B1 known manner, a first end 47 and a second end opposite this 48 on. Adjacent to the first end, a substantially cylindrical portion is provided, whose outer diameter is selected so that the pressure element in the cylindrical portion 43 can slide. As can be seen from the figure, the pressure element in its second region has an open towards the second end spherical segment-shaped recess for receiving the screw head. For the rest, the text is correct 34 and the pressure element 44 with the disclosure in the cited EP 0 732 081 B1 match.
In the 4 The device shown is mirror-symmetrical, so that the other end of the shaft 11 are formed with its head, the socket and the pressure element identical to the previously described.
In operation, the pressure element becomes from the first end 35 into the socket 34 inserted. From the second end 36 here comes the head 21 in the area 45 inserted or pushed in. Then the staff 28 inserted into the remaining U-shaped slot, and over the unscrewing of the outer nut 33 will put pressure on the rod 28 and over this on the head 21 comprehensive pressure element 44 so exercised that rod 28 and ball head 21 be fixed. The procedure is the same on the opposite side.
This version also allows a pivoting of the shaft 11 ' around a given frame angle and the axis of symmetry 37 to, so that alignment or adaptation to be joined rods or rods with screws is possible.
Alternatively, the device may also be designed so that a head with socket in the in 4 shown manner is formed and the other head in the in 2 described monoaxial manner is formed.
The in the 5 to 7 embodiment shown differs from that in the 3 and 4 shown embodiment by the formation of the shaft 111 whose length in some Scope is adaptable to the distance of the rods. Otherwise, this embodiment is true in all details with respect to the heads, as well as the parts 12 . 12 , the bars 18 . 28 and the nuts 19 . 33 with the embodiment according to 3 and regarding the versions 34 , the bars 18 . 28 and the nuts 19 . 33 with the embodiment according to 4 match.
As in particular from 7 can be seen, there is the shaft 111 of three elements. A first shaft part 211 becomes one with one head 210 connected pin-shaped section with a free end 212 educated. The diameter of the pin-shaped portion is such that the pin-shaped portion through the bore 22 the version 12 can be passed. A second shaft part 213 is adjacent to the other head 210 ' formed substantially cylindrical and has a from the free end 214 up to a distance from the head 210 ' extending coaxial bore 215 for receiving the first shaft part 211 on. To fix the connection between the first and second shaft part is a nut described later in detail 216 intended. The second shaft part 213 indicates adjacent to the head 210 ' a first cylindrical portion 217 with a first outer diameter which is dimensioned such that the shaft part 213 through the hole 22 the version 12 ' can be passed. At his head 210 ' opposite end has the first cylindrical portion 217 an external thread 218 that in the 5 and 6 is indicated. Adjacent to the first cylindrical section 217 The second shaft part has a second cylindrical section 219 with an outer diameter smaller than that of the first cylindrical portion. Adjacent to the second cylindrical section 219 the second shaft part has a third section 220 on whose outer wall is at a cone angle towards the free end 214 conically tapered. Further, in the second shaft part 213 at least two, in the illustrated embodiment four, extending from the free end 214 until the first cylindrical section 217 and over the area of the external thread 218 but not to the bottom of the hole 215 extending longitudinal slots 221 intended. Two longitudinal slots each 221 lie opposite each other. By the longitudinal slots tongues are formed on the second shaft portion, which are elastic to some extent, so that with the nut described below 216 a clamping action on the inserted first shaft part 211 is achievable.
The mother 216 is a union or clamping nut. It is elongated and has an internal thread adjacent to one end 222 that with the external thread 218 of the second shaft part 213 interacts. Adjacent to its opposite end, the mother has a section 223 whose inner wall tapers conically towards the second end of the nut. The length in the direction of the longitudinal axis of the nut and the cone angle correspond to that of the second shaft part. The length of the nut is dimensioned so that in on the second shaft part 213 screwed on the conical area 223 the mother with the conical area 220 the second shaft part cooperates.
To secure against twisting the first shaft part 211 opposite the second shaft part 213 has the first shaft part 211 at a distance from its free end 212 a bore extending transversely to the shaft axis through the pin-shaped portion 224 for receiving a corresponding locking pin, not shown. The diameter of the hole corresponds to the diameter of the slots 221 in the transverse direction. The locking pin to be used has a length which is greater than the diameter of the first shaft part 211 and at most as large as the core diameter of the nut 216 is.
In operation, first the first shaft part 211 through the hole 22 the version 12 , in the 3 shown, passed through until the head 210 at the bottom 23 is applied. Then the second shaft part 213 through the hole 22 the other version 12 passed through until the head 210 ' at the bottom 23 is applied. Subsequently, the mother 216 a small piece on the second shaft part 213 screwed so that the conical portions of the nut and second shaft portion not yet cooperate and the first shaft part is inserted. Now, the first shaft part 211 into the hole 215 of the second shaft part 213 so far introduced until a desired total length of the shaft is made. The mother 216 but is not tightened so that a length correction is possible. To secure against twisting then the locking pin described above is through the longitudinal slots 221 and the hole 224 passed. As long as the mother 216 not yet tightened, the length of the shaft 111 be changed even with inserted locking pin, as this together with the first shaft part 211 in the slots 221 is displaceable. Thus, a length correction without twisting the heads 210 respectively. 210 ' respectively.
The connection of the versions 12 . 12 ' with the bars 18 . 28 then takes place as in the context of the embodiment according to 3 described way.
Finally, the mother 216 tightened. By tightening the nut until the conical portions of the nut and the second shank portion cooperate, those described above in the first shank portion become 213 through the longitudinal slots 221 tongues formed compressed and thereby clamp the first shaft part similar to a collet. If it turns out that even a length correction of the shaft 111 is required, only the mother 216 be loosened to cancel the clamping action of the tongues. In practice, the surgeon first screws the screws into the desired positions in the bone and then inserts the rods. The connecting part 10 is usually pre-assembled before insertion, ie the heads are in the respective versions and the shaft part 211 is in the second shaft part 213 plugged in, so that the shaft has a predetermined length. The surgeon then places the connector between the rods to be connected and adjusts the desired length of the shaft member as described above. As a result, for example, one rod can be pulled against the other.
When in the 5 to 7 Shown embodiment of the shaft 111 with the in 4 shown embodiment of the versions 34 is used, the connection of the shaft parts can be done before the heads 210 . 210 with the versions 34 be connected because the shaft parts are introduced with the head side in the sockets.
The in the 5 to 7 embodiment shown is also in the in 2 shown embodiment, in which case one of the heads through the part 13 is replaced and the connecting element then has a monoaxial and a polyaxial connection.
In the embodiments described above, the connecting elements are always explained for connecting rods. In the same way, two shafts of two screws or a shaft of a screw and a rod can be connected to the connecting element and fixed.
