The specific embodiment

With regard to accompanying drawing, same Reference numeral is represented same part in all different accompanying drawings, Reference numeral 100 expressions orthopedic fastener of the present invention.

Apparatus 100 allows threaded fastener 10 around arrow C motion shown in Figure 4, although so that the long axis of this thread spindle is depicted as present aligning, it also can rotate and the oblique vertical long axis line that leaves goblet 130, as shown in Figure 6.The tumbler 120 that is embodied as disk has cylindrical outer surface 122 and smooth end face 124 and bottom surface 126.Therefore, the rotation around arrow C produces round geometric center 128.Disk 120 integrally is fixed on the securing member 10.Tumbler 120 constrains among the goblet 130 with centre bore 132, and screw thread 111 is being equipped on its top.In addition, cut out horizontal stria 134 along this goblet diameter, this stria allows securing member 10 and whole disk 120 both and the bar 136 that crosses goblet 130 long axis to insert wherein slidably.Ask for an interview Fig. 9 to 16, this bar can have any different cross-sectional profiles (for example square, circular, oval or the like).Goblet 130 is sized, so that tumbler 120 is in along periphery 122 tangent registration states with bar 136.Screw 132 is received in dog screw 110 wherein, so that oppress bar 136 near tumbler 120, thereby in case forms suitable orientation, the relativeness of just fixing them.

Substantially, securing member 10 comprises thread spindle 32, has first thread forms 12 at this a end and has second thread forms 14 in the opposite end.As illustrated in fig. 1 and 2, the first end thread forms 12 ends at tip 12, and diameter of thread increase, so that form along with the thread forms that most advanced and sophisticated 16 its spirals strengthen is left in extension.

Second thread forms 14 has bigger diameter but thread profile is similar, and this will go through hereinafter.Preferably, axle 32 has length variable and tapering and 18 to most advanced and sophisticated 16 contractions gradually from the end.Ask for an interview Fig. 1 and 2.

Another nuance of first and second thread forms is: first thread forms 12 has the second thread forms 14 thick screw thread thinner than screw thread.Most advanced and sophisticated 16 is the starting points that are used for inserting skeleton during orthopedic program.For this reason, can on this skeleton, bore locating hole, but after this owing to the tapered feature of first screw thread 12, after this this section is tapping screw thread.It is sharp-pointed to should be noted that both tops of first and second thread forms 70 are.This allows incision normally outside than inner hard skeleton.By means of for first screw thread 12 provides thicker screw thread, this screw thread can insert skeleton quickly than second thread forms 14.Its consequence is, when this skeleton began to be engaged by second thread forms 14, this skeleton can produce axial compression along the direction of two arrow A.In addition, because this thread form geometries, this screw thread can apply the power of radially pointing to inwardly along double-ended arrow B direction.The invention provides the power B and the compression stress A of radially inside or tractive, yet conventional fastener but causes radially outside expansion (rightabout of arrow B) in the prior art.

For

screw thread

12 and 14, the screw thread 60 of securing member 10 is actually the screw thread that the continuous helical shape twines, when it begins from the end during from end-transfer and spirals towards the centre portion of axle 32.Ask for an interview Fig. 3.

Screw thread 60 comprises sharp-pointed top 70 and root 80, and the top limits the external diameter 62 of this screw thread, and root limits the internal diameter 64 of screw thread 60.As Fig. 3 represented in detail, screw thread 60 had upper surface 66, and it extends to sharp-pointed top 70 from the feather edge 84 of root 80.Screw thread 60 also comprises lower surface 68, and it extends to sharp-pointed top 70 from the top edge 82 of root 80.When root 80 extended to top 70, upper surface 66 and lower surface 68 all changeed an angle towards this securing member centre portion on

surface

66,68.

In sectional view, the

surface

66,68 from root 80 straight-line extensions to sharp-pointed top 70.Yet because this profile rotates along with screw thread 60 centers on thread spindle 32 helical forms, upper surface 66 and lower surface 68 all present the curved surface outward appearance.This outer appearnce is similar to a kind of shape, and this shape may be by cone surface straightway at this vertex of a cone down and this circular cone rotation and along forming under the state that moves on its central shaft alignment.Therefore upper surface 66 and lower surface 68 have the three-dimension curved surface that is similar to the cone curved surface, but have linear feature when watching in sectional view.

Upper surface 66 extends to sharp-pointed top 70 with the upper surface angle α that departs from perpendicular to the reference plane of securing member central long axis from root 80.Upper surface angle α is preferably 20 °, but can be any angle between 0 ° and 90 °.And lower surface 68 extends to sharp-pointed top 70 with respect to the following surface angle β of these reference plane from root 80.Lower surface angle β is preferably 40 °, but can change between 0 ° and 90 °.

Upper surface angle α is preferably less than lower surface angle β.According to the method, screw thread 60 have than at external diameter 62 places at adjacency internal diameter 64 places bigger thickness and thereby have bigger intensity, thereby more can bear the load that in skeleton, stands.

The angle of these surfaces (especially upper surface 66) is encouraged radially inner power just.When upper and lower thread forms in conjunction with the time, can present axial compressive force.Note the planomural 54 of Fig. 3.Perhaps, this can replace tip 16 and the darker locating hole of needs.

Except screw thread 60a oppositely and as mentioned above be that second threaded portion 14 has the geometry identical with Fig. 3 than the fine thread (per inch has more screw thread vertically).In other words, for screw thread 14, Fig. 3 observation that can turn over.

Fig. 3 A represents one section screw thread with obvious gradient, for thread forms 14, Fig. 3 A observation that can turn over, and have with shown in the opposite gradient of gradient.

The bottom 129 (Fig. 4) of goblet 130 has space 22, and it extends in being preferably near 90 ° contained circular arc so that allow securing member 10 to rotate around the wide region of arrow C.The rotation that surmounts this space 22 is stoped by hypanthial wall construction 24, wall construction 24 make hole, space 22 and radially extend to roughly be cylindrical goblet 130 both sides stria 134 both remain intact.The free end 138 of goblet 130 need supporting screw 110 so that: (first) compressing bar 136 is to should there being the position, and its method is that (second) exerts pressure to disk 120 and come this disk of clamping by means of (the 3rd) combining free end 138.

The screw thread 60 of screw 110 (Fig. 7 and 16) is actually the screw thread that the continuous helical shape twines, and it starts from 54 places, bottom and upwards spirals to the top 52.Although this single thread structure is preferred, can also adopt other configuration that comprises a series of blended thread, 54 helical forms are wound to top 52 to described a series of blended thread from the bottom together.

This screw thread 60 comprises top 170 that limits major diameter of thread 62 and the root 80 that limits screw thread 60 internal diameters 64.As Fig. 7 represented in detail, screw thread 60 had upper surface 66, and it extends to the top edge 72 at top 170 from the feather edge 84 of root 80.Screw thread 60 also comprises lower surface 68, and it extends to the lower limb 74 at top 170 from the top edge 82 of root 80.When root 80 extended to top 170, upper surface 66 and lower surface 68 all upwards changeed an angle on surface 66,68.Top 170 and root 80 all present the constant distance of the central axis that leaves between top edge 82 and feather edge 84 2.Compare with Fig. 3, top 170 is blunt, and top 70 is sharp.Screw 110 and screw thread 60 thereof also can resemble has sharp-pointed gabarit the top 70 (substituting top 170), and vice versa.

In sectional view,

surface

66,68 from root 80 straight-line extensions to the top 170.Yet when this profile rotated around screw 110 helical forms along with screw thread 60, upper surface 66 and lower surface 68 presented the curved surface outward appearance.This outer appearnce is similar to a kind of shape, and this shape may be by cone surface straightway at the vertex of a cone down and this circular cone rotation and along forming under the state that moves on its central shaft alignment.Therefore upper surface 66 and lower surface 68 have the three-dimensional curve surface that is similar to the cone curved surface, but have linear feature when watching in sectional view.

Upper surface 66 extends to top 170 with the upper surface angle α that departs from perpendicular to the reference plane 4 of central axis 2 from root 80.Upper surface angle α is preferably 20 °, but can be any angle between 0 ° and 90 °.And lower surface 68 extends to sharp-pointed top 70 with respect to reference plane 4 following surface angle β from root 80.Lower surface angle β is preferably 40 °, but can change between 0 ° and 90 °.

Upper surface angle α preferably less than lower surface angle β so that screw thread 60 at the thickness at 170 places, top less than the thickness of thread between the adjacent root 80.According to the method, screw thread 60 have than at external diameter 62 places at adjacency internal diameter 64 places bigger thickness and thereby have bigger intensity, thereby more can bear the load that in skeleton, stands.

Referring now to Fig. 8,, the figure shows screw 132 details on free end 138.The thread spindle of the good and screw 110 of this Kongzui is shape complementarity substantially.This hole comprises screw thread T.The thread form geometries of screw 110 and screw thread T makes the free end 138 of goblet 130 be in the same place along arrow D tractive.

Figure 17 represents skeleton that ruptures and the apparatus that applies 100.Have the securing member 10 following placements of disk 120 and goblet 130, in space 22, rotate as described in disk can resemble so that securing member 10 is positioned in bones.Bar 136 is placed in the stria 134 of goblet 130 then.

This bar is represented as has bending 165 so that show the versatility of this system.Then screw 110 is screwed into the screw thread 111 in the goblet free end 138.When screw was pressed on the bar 136, bar 136, disk 120 and securing member 10 became inflexible.Also tractive is together tightly for free end 138.

Figure 18 is and the similar view of Fig. 4, and it represents embodiment, thereby first and second thread forms have traditional geometry but second thread forms has bigger spiral shell square density limits than the thin screw thread of first thread forms herein.

Except screw 110 comprised the elongated bar 112 of stretching out thereby stretching out from goblet 130 from this screw top, Figure 19 A and B and Figure 16 were similar.Rod 112 necking down region 113 that can comprise in abutting connection with screw 110.Rod is preferably cylindrical and can be made into facet on the necking down region 113 so that with instrument rotary bar 112.

Figure 20 is the perspective view that is fixed on the excellent clamping element 210 on the rod 112.Clamping element 210 comprises and being sized so that admit rod 112 cylindrical hole 212, also comprises narrow slit 214, and narrow slit 214 is positioned on the outer wall and with the groove 216 that stretches into this clamping element body radially to be aimed at.This narrow slit and groove common with run through clamping element and with groove 216 vertical holes 218 cooperations.When narrow slit 214 and groove 216 along arrow D during to tractive together, rod 112 is fixed on should the position.Clamping element 210 roughly is box-like and comprises top surface 222, and except lifting the wall of limit with parallel-oriented two outsides, clamping element hole 212, top surface 222 is planar.Limit wall 224 limits together with top surface 222 and admits grooves, and it is sized so that admit projection 226, and is protruding 226 similar shown on this projection and Figure 20 basal surface.Therefore projection 226 comprises the concave wall 228 of leading to clamping element 210 bodies, so that equal protruding total length between concave wall 228 in the total length between the limit wall 224.Notice that projection 226 departs from 90 ° from top surface 222 (and its recess that is limited by limit wall 224).This allows grip block 210 to be piled up with stable manner, shown in Figure 22 and 23.The bolt 230 of through hole 218 remains on clamping element by nut 232 should the position.Chamfering can be carried out in the turning 203 of clamping element 210.

Figure 24 represents how this alternate embodiment uses this rod to assign to admit the bar of describing among Figure 17 136 as extension.Bar 136 is not to be inserted between disk 120 and the screw 110, but by being admitted as the hole 218 of the clamping element 210 that cooperates as shown in Figure 23, rod 112 is admitted in second hole at the same time.This embodiment is convenient to bar 136 and is used in the outside of patient body.In order to use Figure 24 apparatus, be screwed into securing member 10 (having disk 120 and goblet 130) along the hole.The rod 112 that will have whole screw 110 then is screwed into goblet 130.Rod 112 does not also tighten, thus allow this goblet to tilt (as Figure 25) thus conform to bone contours.Then clamping element 210 is positioned on the rod 112 with bar 136 in couples.Fastening then many rods 112, make it to withstand disk 120 in case with compressing screw 110 near the fixing goblet 130 of the method for disk 120 cylindrical outer surfaces 122.Should be noted that the geometry and the position in stria 134 thereof of disk 120, especially have thread form geometries 12,14 discussed above and can prevent that the work of securing member in skeleton is loosening.Then use bolt 230 and nut 232 with bar 136, clamping element 210 and excellent 112 fix in position.At this moment, fracture (or other orthopedics's anomaly) is stabilized.Though necking section 113 can be made into facet, the end 114 of rod 112 has the drive head outside alternative facet or the facet on rod 112.

Figure 26,27 and 32 represents forward sight, perspective and the side view with Fig. 1 alternative securing member 310 relatively respectively.Do not remake too much explanation with previous embodiment similarity.It should be noted most that the tumbler 120 of Fig. 1 is replaced by saddleback 320.Saddleback 320 has the top surface 336 that is cut into circular arc, and it is sized so that by admitting bar 136 (Figure 30 and 33) with the tangent registration of only about half of circumference of bar 136.Therefore, the radius of curvature of the radius of curvature matching stub 136 of saddleback top surface 336.Compare with Fig. 4 configuration, saddleback 20 has bigger surface with bar 136 and contacts.Because contact area is bigger, this causes only needing less operation that bar 136 and securing member 310 are remained on the fixed position.Also have, the total length of this securing member reduces, thereby causes than lacking thereby make the apparatus overall height compact more, (comparing with Fig. 6) for example shown in Figure 33, this is that this saddleback is actually the external arc of Fig. 6 disk because the major part of disk 120 is replaced by the saddleback 320 than low profile.Therefore, goblet 130 ' also can correspondingly do shortlyer.The outer shoulder 338 of Figure 27 and 32 these saddlebacks of expression, they have with its at the complementary sweep of seat 340 (Figure 33) of goblet 130 ' interior.As in the past, gap 22 allow securing member 310, bar 136 and goblet 130 ' between center on arrow C and relatively rotate.

Threaded fastener 10 can appear among the different embodiment.Threaded fastener tumbler 120 shown in Fig. 1,2 can be replaced, comprise drive head 18 so that press close to the distal portion 18 of second thread forms 14, it is represented as hexagon in the accompanying drawings, but also can form the SOC.HD. cap screw head with spanner recess 21 (Figure 36 B), also be the oval drive head 20 (Figure 36 A) of indent or be used for reliably driving any other profile of securing member.Therefore, Figure 36,37 threaded fastener do not have rotary apparatus.This threaded fastener 10 can replace or directly embed (Figure 38) among skeletons together with other threaded fastener 10.

Figure 39 to 41 represents a modification, and diminished shaft 32 uses the screw thread 12 that Fig. 1 embodiment specialize herein, but uses conventional threads 114 on second threaded sections.Drive head 18 can be Figure 36,36A, 36B or other drive head.

Conventional threads 114 cooperates with the screw 116 of member 118, and member 18 can have the profile of following the skeletal tissue that will be supported.Therefore member 118 may have as using angle 119 illustrational mixing profiles.As shown in the figure, screw thread 12 is imbedded among patient's the skeleton.In this embodiment, screw thread 12 concurs so that axial compression A is provided with screw thread 114, and screw thread 12 also is provided at the radially internal force B that describes in the previous accompanying drawing.

As an alternative, the tumbler 120 that is embodied as solid disk in Fig. 1,2 can be replaced by hollow disc, as shown in Figure 42 A-B, 45A-B.This hollow can have makes faceted profile, octagonal profile 402A for example, other profile for example by tooth 406A at the circular contour 404A that periphery limits, perhaps allow any other profile of retaining thread securing member 10.The securing member 10 of Figure 42 A-B, 45A-B slides on the bar keeper that has complementary contours 402B, 404B for hollow 402A, 404A.The securing member 10 of Figure 45 A-B engages the tooth 406B that is positioned on this bar keeper end 420 again.Bar 422 in this bar keeper stria 424 keeps in abutting connection with securing member 10.The thread segment 426 of stria 424 cooperates with the external screw thread axle 428 of fastening this assembly.
