Abstract

An implant (1) including a bone anchor portion (2) and a body (3) attachable to a rod (4) and provided with two side arms (5) defining a channel (6). Said implant further includes a screw cap (7) for screwing onto the inner walls of the two arms (5), the rod-engaging surface of the cap being provided with rod-gripping portions, and a ring-shaped plate (16) surrounding the arms (5) and having two threaded circular segments extending on either side of the cap between said arms (5). As a result, the plate (16) and the threads of the arms (5) continuously guide the cap (7) so that, with the arms (5) held in position, the cap (7) will not pop out during final high-torque tightening thereof.

Description

Implant for osteosynt ese device, particularly for the spine and corresponding installation tool The present invention has for a ODjeτ- iii αiit for an osteosynthesis device, particularly for the spine, as well as ancillary instrument adapted to facilitate its proper placement . The French Patent Applications 90 01 972

(2658414) 91 10 402 describes an implant comprising a portion for one bone anchor and a fixing body on an osteosynthesis rod, wherein the body comprises two side branches delimiting between them a channel opening onto a rear part of the body (implant body open type), and open on either side of the body in order to receive the rod. The implant also includes a threaded plug adapted to be screwed into internal threads formed on the inner walls of the two lateral branches. An annular disc surrounding the legs of the body to prevent the opening of said legs when the cap is screwed on.

This arrangement realizes the interconnection between the open implant (screw or hook) and the osteosynthesis rod.

other achievements performing this function are known. Thus, in a first device, a conical nut is screwed onto the threaded outer walls of the screw. A second known embodiment comprises an intermediate piece between the stem and a nut, which is fixed onto a thread of this intermediate part. Finally, another device disclosed in the French patent 90 03 694 (2 659 546) includes a threaded plug which is screwed between the legs of the U-shaped body with an interposed olive between the rod and the stopper, a cap capping the ends of the branches of the body 1 to prevent the spacing thereof during the plug screwing.

While in most cases these previous devices are satisfactory, they however have some drawbacks: - the stem may experience some slippage relative to the implant due to insufficient clamping force on it; the end of tightening the screw cap, the force exerted by the latter on the branches of the body of the implant may be high enough to cause

1'écartement branches and thereby the output (AA) of the plug.

- the tappings of the two arms to provide a threaded plug insufficient guidance, the consequences of which are initially a certain difficulty of insertion of the plug, and a risk of introduction of the angled plug, with damage or alteration of the thread 1 'implant.

The invention aims to achieve an implant of the type described in French patent 91 10

402, with which these disadvantages are avoided and an ancillary instrument adapted to facilitate the introduction of the plug and of the pellet.

According to the invention, the tablet comprises two circular sectors threaded, extending from both sides of the stopper between the limbs of the body, and complementary to the threads of said branches in order to realize therewith a continuous thread for screwing the cap . And the screw cap is guided on the one hand, by the two walls of the threaded branches of the body of the implant, and secondly by the two threaded portions of the pellet, complementary to the threads of branches and ensure with those -ci the continuity of the plug guide. Furthermore, the wafer fits the outer shape of the implant body and opposes the ouver¬ ture of the two branches during screwing .from cap. The combination of the above two advantages, namely the continuity of the clamping over the entire circumference and maintenance of branches, eliminates the risk of cap jumping during the final tightening performed at high torque. The ancillary also provided by 1'invention instrument is adapted for fitting of the plug and of the tablet of the implant. It comprises in combination a cork door handle provided with a shaped end adapted to penetrate a conjugated contoured cavity of the plug, and a wafer ring can be slipped over the handle and slidable thereon, one end this ring being provided with means for gripping the wafer.

This tool greatly facilitates the implementation of the cap and the pellet helping to prevent faulty installation of these. Other features and benefits

Figure 15 is a perspective view, with parts cut away, of a cap screwing tool, adapted to be inserted one inside the tubular sleeve of Figures 12 and 13. The implant 1 shown in Figure 1 is intended to a not shown osteosynthesis device, particularly for the spine. It comprises a part 2 for the bone anchor, and which may be either a threaded pin or a hook. The implant 1 also includes a fixing body 3 on a pin 4 to asperities, for example a knurled rod or diamond tips. The body 3 comprises two lateral branches 5 defining between them a channel 6 (Figure 10) opening on a rear portion of the body and open on both sides of the latter in order to receive the rod 4. The body 3 therefore has a section U in a plane transver¬ sal on channel 6.

The implant also includes a cap 7 provided with a thread 8 (Figure 10) and in which is machined a recess 9 formed to be able to receive a shaped end 12, for example hexagonal, a screwing tool 13 (Figure 9) . The cap 7 can be screwed into corresponding threaded holes 14 formed on the inner walls of the branches 5 of the body 3 (Figure 1). The face of the plug 7 into contact with the rod 4 is advantageously provided with attachment means thereto. These means not shown, can be realized for example as described in French patent 88 08 538 (2 633 177).

The implant 1 has an annular pad 16 surrounding the legs 5, which it follows the outer configu¬ ration. The patch 16 comprises two threaded circular sectors 17 which extend vis-à-vis to each other on either side of the plug, in diametrically opposite positions between the limbs 5 of the body 3. The sectors 17 are circular complémen¬ tary threaded bores 14 with which they constitute a substantially continuous thread over the entire periphery of the cap 7. the notches 18 are formed in areas of the outer wall of the pellet 16 located opposite threaded sectors 17. These notches are adapted to receive the ends of a pellet holder ring 19 (shown in Figure 7) which will be described below.

The sections of the patch 16 formed by the threaded sectors 17 are connected by curved portions 20 conforming to the convex outer contour of the branches 5.

The height of the branches 5 of one implant 1 is determined so that the wafer 16 is, in the worst case, flush with the end face of said branches. will now be described with reference to Figures 4 to 10, an ancillary instrument 21 designed to allow easy and correct installation of the plug 7 and the pellet 16.

The instrument 21 comprises a combination tool 13 consists of a cap holder sleeve provided with the polygonal end 12, slotted to take the plug 7 con uguée 1 recess 9 of the plug 7 and the door ring -pastille 19. the latter comprises an actual ring 22, of axis XX, sized to be threaded over the cylindrical stem 13 and slidable thereon. The ring 22 is extended on one side by two longitudinal flexible legs 23 constituting slats terminated by respective ends 24. Legs 23 are preferably diametrically opposed with respect to the ring 22 and their ends 24 are dimensioned to be able s initiate in the notches 18 of the wafer 16. Thus it can be maintained by elastic clamping between the end portions 24. the ends of legs 23 are provided with at least one shoulder inside ent and preferably two diametrically opposed shoulders 29 (figures 5 and 8), which can form axial stops for the wafer 16. on the side opposite to the gripping tabs 23 of the wafer 16, the ring 19 is extended by a longitudinal tab 25, parallel to the axis XX of the ring 22 as the tabs 23, and terminated by a member accro¬ chage to the handle 13. in the example shown this means is formed by an elastic spout 26 forming a "clip "Adapted to be able to snap into a groove 27 corres¬ ponding stop of the wafer ring 19, formed on the surface of the tool 13.

The ring 19 is completed by a longitudinal tongue 28 of hand grip which extends parallel to the leg 25 and is preferably longer than nette¬ ment thereof as shown in Figures 5 and 7.

To mount the ring 19 on the handle holder cap 13, it is sufficient to thread its annular portion 22 of the handle and drag 1'ensemble of the ring to the desired position, for example until the flexible spout 26 comes snaps in the groove 27.

The legs 23 terminate in chamfered ends 23a 1 which facilitate the introduction of the patch 16 between the legs 23 (Fig. 5). The legs 23 diverge elastically and can drag the patch 16 until it abuts against the circular shoulder 29. The ring 16 is then maintained by elastic clamping between the lugs 23. The ancillary instrument 21 , consisting of the handle 13 and cap holder of the ring 19 wafer is used as follows: a) the wafer ring 19 is moved on the tool 13 in the direction which releases the profiled end 12 slotted to taking the cap, the resilient beak 26 then being beyond the groove 27; b) the surgeon performs the outlet of the plug 7, then down the ring 19 until the spout 26 comes snaps in the groove 27; c) at the end of this sliding ring

19, the end portions 24 of the legs 23 come to enter into the notches 18, the disc 16 being retained axially by the shoulders 29; d) one set is positioned over the implant 1 and the wafer 16 and guided on the outside diameter of the body 3. The patch 16 has to be guided on the body 3 to its final position (Figures 1 and 10) in which it is slightly recessed by a distance e. for example about one millimeter (Figure 10) relative to the end faces of the legs 5. The guiding of the patch 16 on the body 3 facilitates the establishment of the plug 7 between the legs 5. This pre-centering allows the guide plug in tarauda¬ ages 14 and 17. Thus, the risk of introduction of the plug 7 obliquely and alteration of the threads 14 and 17 is greatly reduced.

The distance e. separating the end faces of the pellet 16 and the branches 5 corresponds to the step value of the plug 7. In all cases, once the montage, the wafer 16 is never raised with respect to one end the body 3. e) 1 'ancillary cap holder 13 is manoeu¬ vré clockwise for screwing the cap 7 in the threaded holes 14 and 17. During this movement, the cap 7 down to 1 inside the body 3 and the ring 19 rises relative to the plug carrier 13, its relative position with respect to the implant 1 remaining unchanged.

Once screwing the completed plug 7, the ancillary instrument 13, 19 is removed. According to the variant of embodiment shown in Figure 11, the end of unthreaded length of the branches 5 of the implant 1 is deleted (where d is equal to about 1 mm). Therefore, the wafer 16, on which the cap 7 can be previously screwed to a thread engagement as illustrated in the upper part of Figure 11, (step 1, is 1 mm) is flush with the end of the implant 1. for assembly, the assembly formed by the cap 7 of the patch 16 is positioned on open 1'implant 1, the guidance being provided by the patch 16.

In the second embodiment of the ancillary instrument, shown in FIGS 12 to 15, it comprises a door-plug handle 31 consists of a tubular member whose end portion is formed by a flexible fork 32 for taking the plug 7 by one outside the latter and the ends of the arms of the fork 32 (Figure 13). In the part 32 is provided an internal bore 33 adapted to be able to don a tool 34 for gripping the cap 7 by means of a terminal 35 clip to the imprint profile 9.

The ring wafer 36 of this instrument (14) is extended by longitudinal flexible legs 37 adapted to be introduced in the outer notches 18 of the wafer 16. The dishes 38 are formed on each side of legs 37 and are stoppers of the wafer 16, thereby simplifying the arrangement of the ring relative to that of Figure 4. the ring 36 is sized to be threaded onto the sleeve 31 and fitted with a fastening means the latter, such that a longitudinal flexible tongue 39 cut out from the tubular wall of the ring 36, and whose free end carries a ball 41. the latter can come snaps in one of two locking grooves 42 , 43 arranged on the surface of the handle 31 at suitable distances from the fork

32 and with proper spacing with each other. Thus, the ball 41 may come index in either of the grooves 42, 43, which corresponds to two possible positions of the ring 36 on the shaft 31.

The mode of use of the ancillary instrument is as follows:

- assembling the two pieces 31 and 36 by threading the ring 36 on the shaft 31, the ring 36 being placed in the high position, wherein the ball 41 is received in the groove 43 (the tabs 37 are of course placed on the side of the fork 32).

- the plug socket 7 is carried by the fork 32. - is made to slide the ring 36 on the handle

31 until the ball 41 down into the groove 42,

- it performs the taking of the wafer 16 by the flexible flaps 37 of the ring 36,

- positioning one assembly on open 1'implant then introduced the screwdriver 34 into the bore

33 of tubular sleeve 31,

- and finally proceeds to the tightening of the closure 7 in the implant.

Various alternative embodiments may be made to the implant and the ancillary instrument of implementation of the cap and the pellet, as part of the invention. Thus the wafer ring may be made of any other equivalent manner, the abutment elements épaule¬ 29 may for example be any number, or even be reduced to one extending over a sufficient angular sector.
