Embodiment
With reference to specific embodiments and the drawings, the invention will be further described, elaborates in the following description more
Many details are to facilitate a thorough understanding of the present invention, still the present invention obviously can be with a variety of different from the other of this description
Mode is implemented, and those skilled in the art can be in the case of without prejudice to intension of the present invention according to practical situations
Make similar popularization, deduction, therefore should not be limited the scope of the invention with the content of this specific embodiment.
Accompanying drawing, and should not be in this, as only as an example, it is drawn according to the condition of equal proportion
The protection domain of actual requirement of the present invention is construed as limiting.
The present invention, which is used, can be achieved 360 degree between the design philosophy of integral type interval cushion block, any two pieces of cushion blocks
Rotation, by the altitude combination of polylith pad, can measure the gap of femur and shin bone, select suitable prosthese to plant
Enter.
As shown in Fig. 1 and Fig. 2, Fig. 3, gap pad component includes multiple rotation cushion blocks 2,3,4 and main
Body cushion block 1, each rotation cushion block and main body cushion block have shank and pad portion respectively.Wherein, rotation cushion block 2 has
Shank 22 and pad portion 21.Main body cushion block 1 has shank 12 and pad portion 11.Rotating cushion block 3 has shank 32
With pad portion 31.Rotating cushion block 4 has shank 42 and pad portion 41.The thickness in each shank and corresponding pad portion can be with
It is identical, can also be different.The quantity of wherein rotation cushion block 3 is 2, and the quantity of rotation cushion block 2 is 3,
The quantity for rotating cushion block 4 is 1.In another embodiment, the quantity of the rotation cushion block of different-thickness can not
Together.The shank of each rotation cushion block 2,3,4 is arranged on the shank 12 of main body cushion block 1 by pivot 27 respectively,
Pivot 27 can be linked together them with tie spacer 28,29 and fastener 30, allow that rotation cushion block exists
360 degree or the interior rotation of other angular ranges.Fastener 30 is demountable or non-removable.
Between the rotation cushion block 2,3,4 and main body cushion block 1 also include a positioner, for make rotation cushion block 2,
3rd, 4 overlapped with the upper-lower position where main body cushion block 1.
As shown in figure 3, the shank 22,32,42 and the shank of main body cushion block 1 of rotation cushion block 2,3,4
12 have under pairing state coaxial line to line bar hole 14,13, it is positioner, in other words, to line
The hole that rod aperture 14,13 is collectively constituted run through be paired together rotation cushion block 2,3,4 shank 22,32,
42 and the shank 12 of main body cushion block 1, can to line bar 16 to line bar hole 14,13 for being passed through to line bar 16
To be existing MicroPortTo line bar.In the embodiment shown in the drawings, there are three side by side
The shank 22,32,42 and main body cushion block of rotation cushion block 2,3,4 are separately positioned on to line bar hole 14,13
On 1 shank 12.
In preferred embodiments as shown in Figure 5, and unlike the embodiment shown in figure, positioner is different,
It is to set the positioner positioner to be a baffle plate 19 in the side of main body cushion block 1.When rotation cushion block 2,3,
4 side and the position of main body cushion block 1, when postive stop baffle 19 is in close contact, rotation cushion block 2,3,4 with
The upper-lower position of main body cushion block 1 is overlapped.
For example, the thickness in the pad portion 22 of rotation cushion block 2 is 2mm, rotates the thickness in the pad portion 32 of cushion block 3
Spend for 3mm, the thickness for rotating the pad portion 42 of cushion block 4 is 5mm.
As shown in Fig. 2 for ease of using, can be marked in each pad portion 11,21,31,41 mark character 5,
6th, 7,8,9,10,11, mark character 5,6,7,8,9,10,11 be meant that group to rotating pad
Block component thickness corresponding with main body cushion block, its be respectively MINUS 2MM, 10mm, 12mm, 14mm,
17mm、20mm、25mm。
In another preferred embodiments, shank of the visualization mark positioned at each part.Can be in advance in rotation cushion block
Shank color or numeral or other symbols are set, the gap for indicating current shin bone and femur for doctor.
By actual demand and corresponding surgical technic, after implementation proximal tibia is ready to complete with distal femur plane, stretch
Knee joint, selects first rotation cushion block 2 mutually to be assembled with main body cushion block 1, now rotates the mark on cushion block 2
Character (6) is shown as " 10mm ", and meaning actual " 10mm " that mark character 6 is shown can be corresponded to
It is 10mm MicroPort for thicknessTibial insert.Then, between insertion " 10mm " is thick
Gap pad component (1,2) is among the gap of femur when stretching and shin bone.If " 10mm " thick gap
Cushion block pad component (1,2) is with stretching interdigit gap mismatch, it may be necessary to extra osteotomy, then can increase
Rotate cushion block 2,3,4.The thicker gap pad component (1,2,3,4) of composition, is inserted into and stretches interdigit
Be estimated in gap, until stretch interdigit gap tightness it is suitable untill.In addition, if between " 10mm " is thick
Gap pad component (1,2) and stretch interdigit gap mismatch, it is also possible to which main body cushion block 1 assesses extra osteotomy
Amount, to realize that knee joint is stretched completely.Then, user, select corresponding correct position to line bar hole, insertion
MicroPortTo line bar 16, come check femur and shin bone to line situation.
In one embodiment, the actual (real) thickness of the gap pad component (1,2,3,4) after the completion of assembling is to cut
The thickness of the thickness of the condyle of femur gone and the tibial tray prosthese that will be implanted into, the thickness of tibial insert prosthese it
With.
Although the present invention is disclosed as above with preferred embodiment, it is not for limiting the present invention, any this area
Technical staff without departing from the spirit and scope of the present invention, can make possible variation and modification.Therefore,
Every content without departing from technical solution of the present invention, what the technical spirit according to the present invention was made to above example appoints
What modification, equivalent variations and modification, each falls within the protection domain that the claims in the present invention are defined.
