[0024]FIG. 1 is a perspective view thereof, according to a first embodiment; [0025]FIG. 2 is a perspective view thereof, after it has been fitted on a fractured humerus; [0026]FIG. 3 is a view thereof on an enlarged scale, in cross section along the line III-III in FIG. 1; [0027]FIG. 4 is a perspective view thereof, according to a second embodiment, after it has been fitted on a fractured humerus, and [0028]FIG. 5 is a perspective view thereof.
[0029] FIGS. 1 to 3 represent an external fixator 1 with which it is possible to maintain two bone parts relative to one another by means of pins 2 inserted in these bone parts. In the example shown in FIG. 2, the fixator 1 is used to immobilize a humerus fragment 3 relative to the rest of the bone with a view to repairing the fracture 4. [0030] The pins 2 are of conventional type. Each of them comprises a self-drilling part 5 permitting its insertion in the cortical substance of a bone, and a square head 6 allowing it to be maneuvered in rotation. [0031] The fixator 1 comprises a rigid bar 7 and two pin-holder assemblies 8, 9. [0032] The bar 7 is made of a resin reinforced with carbon fibers and is molded in such a way as to present a cylindrical main part 10 and a spherical part 11 at one end. [0033] The assembly 8 comprises a one-piece body 12 made of synthetic or metal material. [0034] This body 12 has a bore passing through it to permit its engagement by sliding on the part 10 and its pivoting about the latter, and a tapped hole formed perpendicular to this bore. This hole opens into the bore and receives a set screw 13 with a hexagonal cavity. This screw 13, when tightened, makes it possible to clamp the bar 7 in said bore in order to immobilize the body 12 in a defined position relative to this bar 7. [0035] The body 12 additionally has two bores for sliding engagement of two pins 2, and two tapped holes, each of which is formed perpendicular to one of these bores. Each of these holes opens into the corresponding bore and receives a set screw 14 with a hexagonal cavity. These screws, when tightened, make it possible to clamp the pins 2 in said bores in order to immobilize these pins 2 in a defined position relative to the body 12. [0036] The edges of the body 12 are rounded so as not to cause injury. [0037] The assembly 9 also comprises a one-piece body 15 made of synthetic material or metal. [0038] This body 15 has a general annular shape. It has a recess 16 which opens into one of its axial faces 17 and a tapped hole 18. [0039] As is shown in FIG. 3, the recess 16 has a zone 20 of partially spherical shape with a radius slightly greater than that of said spherical part 11. This zone 20 has a shape such that it encloses more than half of the part 11 and is connected to the face 17 via a conical zone 21. [0040] The hole 18 is formed radially relative to the recess 16 and opens into the latter. It is positioned in such a way that its axis is situated beyond the center of the zone 20, toward the zone 21. [0041] This hole 18 and the recess 16 have respective dimensions which are such that the zone via which this hole 18 is connected to the recess 16 permits engagement of the part 11 in the recess 16 until this part 11 is received in the zone 20. [0042] The aforementioned respective dimensions of the part 11 and of the zone 20 mean that this part 11 is received in the zone 20 without lateral play but with a possibility of articulation. The zone 21 forms a clearance which permits this articulation. [0043] The hole 18 receives a set screw 22, with a hexagonal cavity, the radially internal end of this screw having a frustoconical shape. During tightening of this screw 22, this end will bear against the part 11 such that it is received in the zone 20 and makes it possible to clamp said part 11 in this zone 20 in order not only to immobilize the assembly 9 relative to this part 11 but also to ensure that the part 11 is retained in the recess 16. [0044] The body 15 additionally has two bores for sliding engagement of two pins 2, and two tapped holes, each of which is formed perpendicular to one of these bores. Each of these holes opens into the corresponding bore and receives a set screw 23 with a hexagonal cavity. These screws 23, when tightened, make it possible to clamp the pins 2 in said bores in order to immobilize these pins 2 in a defined position relative to the body 15. [0045]FIGS. 4 and 5 show a fixator 1 very similar to that which has just been described, and the elements or parts which are repeated here are designated by the same reference numbers as above. [0046] In this case, the assembly 9 has a body 15 with a �crook� shape, and the bores receiving the pins 2 are formed at the ends of this �crook�. These bores are thus perpendicular to one another, so that this assembly 9 permits positioning of perpendicular pins 2 if this proves necessary for the fixation which is to be performed. [0047] It will be evident from the above that the invention makes available a fixator whose structure is very simple and inexpensive to manufacture, but nonetheless has just as many possibilities of use, particularly as regards the possibilities of spatial orientation of the pins 2. This structure in particular means that the fixator can be discarded after one use and can be supplied in a sterilized state, ready for use.
