Definitions
- intervertebral prostheses which consist of two prosthesis plates each to be connected to a vertebral body and a prosthesis core arranged between them
- insertion instruments are known (EP-A-333 990) which have two prosthesis holders at their front ends, each of which holds a prosthesis plate.
- the prosthesis holders are connected to each other by a parallel guide, which allows the prosthesis plates to be brought closer together first so that they can be inserted more easily into the narrow intervertebral space, and then spread apart (with the adjacent vertebrae) to insert the prosthesis core between them can. Then the prosthesis holders are brought together again so that the prosthesis plates enclose the prosthesis core in its functional position, and the instrument is removed.
- the known instrument is designed as pliers that are angled in relation to the direction of the prosthesis holders, which should coincide with the median direction of the body, in order to allow the insertion not to be in the way of the prosthesis core. Nevertheless, the insertion of the prosthesis core is difficult.
- a pair of guide rods and an upper guide rod is formed, which are articulated at the rear end and carry prosthesis holders at their front ends. They form a guideway for an expansion element. If this is driven forward between them by means of a rack, it spreads the ends of the bars apart and at the same time pushes the prosthesis core in front of it until it has reached the desired end position. The expansion element is then withdrawn in order to bring the prosthesis plates closer to the prosthesis core. The spreading movement is inevitably coupled with the insertion of the prosthesis core, so that the spreading process cannot be observed separately from the insertion of the prosthesis core and is difficult to observe.
- the invention seeks to provide an instrument which allows the prosthesis plates to be expanded independently of the insertion of the prosthesis core and which nevertheless facilitates the insertion of the prosthesis core.
- an instrument for inserting an intervertebral prosthesis which has two prosthesis holders for a pair of prosthesis plates which are connected by a parallel guide and can be spread apart.
- the first of these prosthesis holders is fixed to an elongated body of the instrument arranged in accordance with its longitudinal direction.
- the second prosthesis holder is held on the instrument body by means of the parallel guide. All the parts connecting the instrument body and the second prosthesis holder are arranged outside a central passage opening running in the longitudinal direction of the instrument body, the width of which corresponds at least to the transverse dimensions of the prosthesis core to be inserted between the prosthesis plates and a prosthesis core holder provided therefor.
- the prosthesis core can be easily inserted through the insert instrument with the aid of a prosthesis core holder, the links of which form a guide for the prosthesis core or the prosthesis core holder. So that the surgeon easily finds the position of the prosthesis core holder in which the prosthesis core has reached the desired position between the prosthesis plates when inserting the prosthesis core, the insertion instrument and the prosthesis core holder are expediently provided with interacting stops which determine this end position.
- a semi-trailing arm can be provided, the first end of which is articulated on the instrument body in the longitudinal direction thereof. Its second end is articulated to the second prosthesis holder. Its first end is connected to an actuating device which can be moved in the longitudinal direction of the instrument body. If the actuating device is moved in the direction in which the first end of the semi-trailing arm is moved in the direction of the articulation point of its second end, the semi-trailing arm straightens up and thereby spreads the second prosthesis holder away from the instrument body and the first prosthesis holder, and vice versa ,
- the semi-trailing arm can be part of a parallel scissor guide.
- the semi-trailing arm is expediently provided in pairs symmetrically on both sides of the instrument body in order to avoid an asymmetrical power transmission that tends to tilt.
- the actuating device expediently comprises a handle and a translation device.
- the translation device can be formed, for example, by a threaded spindle. It has proven to be more expedient to design the actuating device as a handle lever which is connected to a shorter working lever which forms the translation device. It is expediently arranged in such a way that it simultaneously converts the lateral movement of the handle into the operating direction running in the longitudinal direction of the instrument body.
- the semi-trailing arm can be hinged at its first end to a slide guided on the instrument body in its longitudinal direction. Instead, it is also possible for it to be a member of a pair of toggle levers, the actuating device acting directly or indirectly on the knee point of the pair of levers.
- an actuating device which comprises an actuating lever which is pivotally articulated at its front end to the instrument body or the first prosthesis holder.
- the pivot axis runs transversely to the longitudinal direction of the instrument body and to the direction of expansion. Behind this axis, the lever has a stop that is directly or indirectly acts on the second prosthesis holder.
- the lever At the rear end, the lever is designed so that it can be operated by hand. In the unexpanded state of the instrument, the lever is at a certain angular distance from the instrument body. Will it be by hand or suitable
- the stop moves the second prosthesis holder away from the first prosthesis holder and spreads them in this way. Thanks to the leverage, high spreading forces can be transmitted.
- the stop acts on an oblique link which is connected to the second prosthesis holder and which can also be part of the parallel guide.
- the lever is expediently not an integrating component of the instrument body, but rather is designed in such a way that it can be attached to the instrument body intraoperatively and can be released again. This has the advantage that the instrument body is not weighed down by the spreading mechanism formed by the lever in those operating phases in which spreading does not take place or need not be maintained. This actuator may deserve protection regardless of the features of the claims referred to.

- the prosthesis holders 52 are fork-shaped and open at the end. Their lateral legs form guides for the edge of the prosthesis plates 53. Their direction coincides with the longitudinal direction of the
- the prosthesis bodies 51 have a striking plate 54. By striking this plate, the prosthesis plates 53, held by the prosthesis holders 52, can be driven between two vertebral bodies.
- the lower prosthesis holder 52A (FIGS. 9 and 10) is fixed to the instrument body 51 and is even connected in one piece in the example shown.
- the upper prosthesis holder 52B is connected to the instrument body 51 by means of a scissor arrangement consisting of scissor members 56, 57.
- the scissors arrangement 56, 57 is provided in pairs on both sides of the instrument body and is designed in such a way that the upper prosthesis holder 52B is only perpendicular to the lower one Prosthesis holder 52A and can move parallel to this.
- the prosthesis holders can largely be approximated to one another (FIG. 1) in order to be able to be driven more easily into the intervertebral space. They can be spread apart together with the adjacent vertebral bodies (FIGS. 2 and 3) in order to give space for the insertion of the prosthesis core 77 between the prosthesis plates 53. Then they are brought closer together again in order to hold the prosthesis core in the desired position. The instrument can then be removed.
- the rear bolts 58, 59 of the scissor members 56, 57 slide in elongated holes in the instrument body 51 or the plate 73, which continues the upper prosthesis holder 52B to the rear.
- the direction of the elongated holes corresponds to the longitudinal direction of the instrument.
- the front bolts 60 of the scissor members 56, 57 are rigidly connected to the prosthesis holders 52.
- a device is provided which displaces the rear bolt 58 of the scissor member 57 in the longitudinal direction of the instrument. That is what
- Handle lever 61 is provided which is pivotable on the instrument body about an axis 62 and has a working lever 63 which acts on the rear end of a sliding block 64, which is part of a T-shaped carriage 65 (FIGS. 4 and 6), on the crosshead of which rear bolts 58 of the scissor members 57 arranged on both sides are articulated.
- the carriage 65 is guided in the longitudinal direction of the tool body. It can be seen in FIG. 4 that the parallel edges of the sliding block 64 are guided between correspondingly parallel edges 66 of a cutout in the instrument body. In Fig. 3 it can be seen that the
- the plate 73 which carries the upper prosthesis holder 52 at its front end, is - as in the exemplary embodiment described above - carried by the instrument body 51 by means of a screen arrangement 56, 57.
- the spreading device is implemented independently of the scissor arrangement.
- the links 100, 101 form a toggle lever arrangement. One end of these links is connected to the instrument body 51 or the plate 73. Its other end forms the knee 103, on which the end of a link 102 engages, the other end 104 of which is connected to the actuating device.
- the connection can be made as shown in FIG. 6.
- the spreading arrangement which is independent of the scissor arrangement 56, 57, has the advantage that the angles at which the links 100, 101 and 102 are stressed do not take into account a parallel leadership function can only be measured with a view to a favorable power transmission.
- the hand lever 61 is supplemented by a threaded spindle 71 with a toggle nut 72, which facilitates the process and allows the instrument to be temporarily locked in the spread position.
- a channel-like space is formed between the instrument body 51 and the plate 53, which continues the upper prosthesis holder 52 to the rear, and between the lateral scissor assemblies 56, 57.
- the prosthesis core 77 can be guided between the prosthesis plates 52 by means of an instrument 76, which is guided between the links 56, 57 (FIG. 3).
- the instrument 76 has a stop 75 which bears against the rear edge 74 of the plate 73 when the prosthesis core 77 has reached exactly the intended position between the prosthesis plates 52.
- the prosthesis guides 52 Behind the receiving space for the prosthesis plates 53, the prosthesis guides 52 contain a guide groove 80 which runs in the longitudinal direction of the instrument and thus in the sliding direction of the prosthesis holders 52. It contains a slide 81, the front end 82 of which strikes the edge of the prosthesis plate located in the prosthesis holder and is therefore referred to as a prosthesis stop.
- the rear end of the slide, not visible in FIGS. bers 81 is rigidly connected to a rod 83 which is also guided in the longitudinal direction of the instrument.
- the rear end of the rod 83 mounted in the instrument body 51 is, as shown in FIG.
- a stop element 84 fastened to a stop element 84, the nature of which will be explained later. It can also be moved in the longitudinal direction of the instrument.
- the stop element 84 is in turn rigidly connected to a push rod 86 which is mounted in the instrument body 51 so as to be longitudinally displaceable and leads to a handle 87.
- the push rod 86, the stop element 84, the rod 83 and the slide 81 are moved forward in order to push the prosthesis plate 53 out of the prosthesis holder 52.
- the surgeon's hand can be supported on a pin 88 which is firmly connected to the instrument body 51.
- the movement of the handle 87 has an immediate effect only on the slide 81, which is arranged in the lower part of the instrument, namely in the instrument body.
- a movement transmission device is provided so that the slides 81 of both prosthesis holders move synchronously.
- the rod 83 controlling the slide 81 of the upper prosthesis holder is fixedly connected at its rear end to a stop element 85 which, like the stop element 84 of the lower prosthesis holder, is movably guided in the longitudinal direction of the instrument.
- the lower stop element 84 has protruding stop legs 90 on both sides, which lie behind and adjacent to the legs 91, which protrude from the upper stop element 85 on both sides.
- Each slide 81 carries a projection 95 rigidly connected to it and a block 96 guided in the longitudinal direction of the slide, which forms the vertebral stop with its end face.
- the end faces of the vertebral stops 96 finally contact the ventral edges of the vertebral bodies.
- the distance between the end faces of the vertebral stops 96 and the prosthesis plates thus determines the depth at which the prosthesis plates reach the intervertebral space. This depth can be changed by adjusting the swirl stops 96 on the slides 81.
- the instrument body 51 is connected near its front end by means of a pivot axis 30 to the front end of an actuating lever 31 which extends approximately parallel to the instrument body 51 and can be gripped at its rear end 32 in the manner of a pliers lever to be pressed against the instrument body 51. It has a stop projection 33 or a pair of stop projections 33 located on either side of the instrument body, which extends to a counter-stop surface 34 of the second prosthesis holder or a plate 73 connected to it. If the prosthesis holders 52A, 52B are not spread, the actuating lever 31 protrudes from the instrument body 51 at an acute angle. When pressed against the instrument body 51, the stop protrusion 33 lifts the prosthesis holder 52B to spread it from the prosthesis holder 52A.
- FIGS. 9 and 10 A similar embodiment is shown in FIGS. 9 and 10.
- the same reference numbers designate the same parts. Because of their description, reference can be made to the example above.
- the stop projection 33 does not engage directly on the
- the stop projection 33, the stop bolt 35, the axis 30 and the end-open bearing bore 37 are provided in pairs in order to allow a secure connection to the instrument body and the space between the parallel guides 56, 57, the serves to insert the prosthesis core, to keep free of construction parts.
- the operating lever 31 can be moved by hand.
- a threaded spindle 38 is also provided, on which the actuating lever 31 can be approached with high force to the instrument body 51 by means of a nut 39 and by means of which the spread position of the instrument can be secured.
- the actuating lever 31 can also be detached from the instrument body in the area of the spindle 38.
