Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing.It should be noted that for
The explanation of these embodiments is used to help understand the present invention, but and does not constitute a limitation of the invention.In addition, disclosed below
The each embodiment of the present invention involved in technical characteristic can be combined with each other as long as they do not conflict with each other.
A kind of lower limb shin bone line of force fixator as shown in Figure 1, Figure 2 and Figure 3, including 2 girdle device 1 and 1 piece straight-bars 2,
Girdle device 1 is " C " type ring, link block 3 is equipped on two end faces of 1 opening of girdle device, and 2 link blocks 3 are symmetrical arranged,
The adjacent surface of 2 link blocks 3 is symmetrically arranged with shaft 4 and card hole 5, and card hole 5 is located at 4 top of shaft, and the center of card hole 5 with turn
The center of axis 4 is located along the same line, and compressed spring 9 and strip 10 are equipped in card hole 5；Straight-bar 2 is the column that cross section is rectangle
Shape structure is symmetrically arranged with connecting hole 7 on the symmetrical two sides of straight-bar 2, and shaft 4 is set in connecting hole 7, straight-bar 2 with connect
Block 3 is hinged, and the position that 4 side of shaft corresponds to card hole 5 is equipped with card slot 6, and card slot 6 is located at 7 top of connecting hole, and the center of card slot 6
It is located along the same line with the center of connecting hole 7.
Straight-bar 2 is telescopic rod, and straight-bar 2 includes outer cylinder 201 and inner cylinder 202, and inner cylinder 202 is set in outer cylinder 201, outer cylinder 201
Side wall is equipped with clamping screw 203.When adjusting 2 length of straight-bar, inner cylinder 202 is extracted out from outer cylinder 201, after reaching appropriate length
Inner cylinder 202 is compressed by clamping screw 203 to be locked.
Card hole 5 runs through link block 3, and strip 10, other end setting limit is arranged close to one end of 3 adjacent surface of link block in card hole 5
Position bolt 8.
The length of strip 10 is greater than the depth of card slot 6, less than the depth of card hole 5.
Girdle device 1 includes connecting spring 102 and linkage section 101, and linkage section 101 has 2, is respectively arranged on connecting spring 102
Both ends.
When in use, 2 girdle devices 1 are separately mounted to the corresponding leg position of shin bone for needing to intercept, by girdle device 1
On 4 holding of shaft in the connecting hole 7 on straight-bar 2, straight-bar 2 and girdle device 1 are hinged, and in the course of surgery, doctor is to shin bone
It is intercepted, so that straight-bar 2 is rotated relative to shaft 4, when the interception amount of shin bone is appropriate, girdle device 1 and straight-bar 2
Perpendicular, the strip 10 in card hole 5 into card slot 6, and then locks under the elastic force effect of compressed spring 9 at this time, when operation,
Straight-bar 24 rotates around the shaft with the increase of shin bone interception amount, when straight-bar 2 is in 90 degree relative to girdle device 1, strip
10 under the action of 9 elastic force of compressed spring, cannot continue to rotate into card slot 6, and then by the locking of straight-bar 2, illustrate shin at this time
The interception amount of bone is appropriate, can provide intuitive reference to doctor during surgery.
Straight-bar 2 can be by adjusting the length of straight-bar 2 since the tibia length of each patient is all different using telescopic rod
