Description
Technical field
The utility model relates to medical instruments field more particularly to a kind of 3D printing osteotomy for the operation of knee joint varus
Guide plate.
Background technique
Knee joint varus is a kind of lower limb malformation disease, when being mainly shown as that two lower limb are stretched naturally or stood, in two foots
Ankle can collide and two knees cannot be drawn close；At knee joint, the shin bone of shank has rotated inward an angle.The basis that out knee is formed
The reason is that calcium deficiency, heredity and rickets, immediate cause be it is bad walk appearance, stance, sitting posture and some movements.Out knee is more common in children
Phase in childhood, the complication such as Yi Yinfa knee joint osseous arthritis.
The characteristics of due to upgrowth and development of children, most out knees can be corrected voluntarily, but with super weight children's
Increasingly increase, operative treatment should also be carried out for serious out knee.
Knee joint varus gesture takes the outer lateral incision of knee joint, rises from the outside of joint, proximally 10~15cm of vertical extension.
After cutting skin and subcutaneous tissue, separates vastus medialis and pull it toward front, cut and appear on the inside of femur and knee joint.So
Afterwards, it determines the plane of osteotomy and carries out osteotomy, the plane of osteotomy is parallel to knee joint, in the upper limb of intercondylar notch of femur.First
In the outside of femur, the far and near end of osteotomy line is to squeezing into Kirschner wire on the inside of femur.Then it is truncated with a chainsaw in the outside of femur
Distal femur removes suitable triangle bone block according to the angle that the knee joint of preoperative measurement turns up, and the inside of osteotomy uses osteotome
Truncation is to prevent from shifting.
It can be seen that knee joint varus operative treatment needs osteotomy, and bone is rotated into specific angle to correct varus,
However in the course of surgery, it is difficult to which the angle holding the optimum position of osteotomy and specifically rotating usually causes surgical effect to pay no attention to
Think.

Distally.In the present embodiment, since the part that bone distal end sections rotation is less than bone proximal end, the quantity of third pin hole 3
It can be only 1.In addition, the range of third pin hole 3 and the range of first pin hole 1 be not be overlapped, to avoid the first pin hole 1.?
In some specific embodiments, the diameter of third pin hole 3 is 4mm.
One or more 4th pin hole 4 settings are identical as the diameter of the third pin hole 3 on second part 62,
And it is greater than the diameter of first pin hole 1.4th pin hole 4 is optionally steinman pin hole, for positioning steinman pin direction of insertion.It inserts
The steinman pin for entering the 4th pin hole 4 is used to be auxiliarily fixed and rotate the second part 62 and then is auxiliarily fixed and rotates the proximal end of bone.
In the present embodiment, since bone proximal end is greater than bone distal end, the quantity of the 4th pin hole 4 can be only 2.In addition, the 4th
The range of pin hole 4 and the range of second pin hole 2 be not be overlapped, to avoid the second pin hole 2.In certain embodiments,
The diameter of four pin holes 4 is 4mm.Further, third pin hole 3 and the 4th pin hole 4 are not located along the same line based on matrix 6.
Two positioning units 8 with through hole are located at the first partial 61 and second part 62.At this
In embodiment, 3D printing osteotome guide plate provided by the utility model further includes two connecting columns 7.Connecting column 7 is respectively by two
Positioning unit 8 is connected to the first partial 61 and second part 62.Specifically, in the present embodiment, each positioning is single
Member 8 includes multiple positioning columns 81 of identical quantity, and each positioning column 81 has a through hole.In certain embodiments,
The outer diameter of each positioning column 81 is 5mm, and the diameter (i.e. the internal diameter of positioning column 81) of through hole is 4mm.3D printing osteotome guide plate
It is just connect with bone, the first partial 61 and the second part 62 connect, positioned at the positioning unit 8 of the first partial 61
Through hole axis be located at it is described second part 62 the positioning unit 8 through hole axis misalignment (referring to Fig. 3).
Optionally, the angle between the axis of the through hole of positioning unit 8 and osteotomy leading line is 80 degree to 90 degree.When performing the operation,
When the first partial 61 and the second part 62 are separated along the osteotomy leading line 5, clava (such as Orthopedic rod) passes through each institute
Through hole is stated, the bone that first partial 61 and first partial 61 connect is rotated, so that being located at the described fixed of the first partial 61
The axis of the through hole of bit location 8 is aligned with the axis of the through hole for the positioning unit 8 for being located at second part 62, by
This realizes the rotation of knee joint varus.
When two positioning units 8 include multiple positioning columns 81 of identical quantity, positioned at multiple positioning of first partial 61
Column 81 has one-to-one relationship with the multiple positioning columns 81 for being located at the second part.When cutting muscle 9 is unbroken, the first game
Portion 61 and the second part 62 do not separate, and the axis positioned at the through hole of the positioning column 81 of the first partial 61 is corresponding
Be located at it is described second part 62 the positioning column 81 through hole axis misalignment.When performing the operation, the first partial
61 and second part 62 along the osteotomy leading line 5 separate when, clava (such as Orthopedic rod) pass through each through hole, rotation
The bone that first partial 61 and first partial 61 connect, so that being located at the through hole of the positioning column 81 of the first partial 61
Axis it is corresponding be located at it is described second part 62 the positioning column 81 through hole axis alignment.In other words, exist
In such embodiment, when the first partial 61 and the second part 62 connect, not mutual corresponding two positioning columns are had
The case where axis alignment of 81 through hole, however, such situation is also within protection scope of the present invention.
Fig. 1 to Fig. 5 is only each embodiment for schematically showing the utility model, but the utility model is not with this
It is limited, for example, the first pin hole to the quantity of the 4th pin hole and position can generate variation according to different bones and requirement；Positioning is single
The quantity of positioning column and position can also generation variations etc. according to different bones and requirement in member.The mode of these variations all exists
Within the protection scope of the utility model, it will not be described here.
3D printing osteotome guide plate provided by the utility model for the operation of knee joint varus has the advantage that
The utility model is intended to by being accurately positioned the osteotomy leading line of 3D printing osteotome guide plate to preset
Position, and preset angle can will be turned to by positioning unit in knee joint, it is accurate for knee joint varus bone-culting operation
Property be of great value, reduce operation risk and gesture time, improve surgical effect.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, should all regard
To belong to the protection scope of the utility model.
