Specific embodiment
It is right with reference to the accompanying drawings and examples in order to keep the purpose of this utility model, technical solution and advantage clearer
The utility model is described in further detail.
9, the embodiments of the present invention: the structural schematic diagram of long bone osteotomy device is as shown in Figures 1 and 2, including two
Sliding rail 1 disposed in parallel is symmetrically provided with two arc-shaped guide rails 2 at the both ends of two one slide rails 1, and the two of the arc-shaped guide rail 2
End is provided with U-shaped fork 9, and arc-shaped guide rail 2 is slidably connected with two one slide rails 1 simultaneously by the U-shaped fork 9 at both ends, the arc-shaped guide rail 2
Length direction on be provided with perforative sliding slot 11, limit screw 10 passes through the connection of 11 rear thread of sliding slot from the side of U-shaped fork 9
On the other side of U-shaped fork 9；Two splenial bone pincers are symmetrically provided on two arc-shaped guide rails 2, the splenial bone pincers include symmetrical
The left caliper 3 and right caliper body 4 of setting, left caliper 3 and the clamp handle of right caliper body 4 are connected by 5 hinge of shaft, the lower end of right caliper body 4
It being slidably connected by sliding lock 8 and arc-shaped guide rail 2, the sliding lock 8 includes the sliding sleeve 8.1 for being fixedly connected on 4 lower end of right caliper body,
Arc-shaped guide rail 2 is passed through out of sliding sleeve 8.1 and is slidably connected with sliding sleeve 8.1, and lock is provided on the side wall of sliding sleeve 8.1
Tight screw 8.2.It is connected in the inboard hinge of right caliper body 4 and adjusts screw 6, adjust the through-hole 12 that screw 6 passes through 3 lower end of left caliper
It is connect afterwards with adjusting nut 7.The center of arc of the arc-shaped guide rail 2 and the jaw center that splenial bone clamps are concentric.3 He of left caliper
The jaw section of right caliper body 4 is arc-shaped structure, convenient for clamping femur.It is respectively provided on the inside of the jaw of the left caliper 3 and right caliper body 4
There is anti-skid chequer 13.Graduation mark is provided on the sliding rail 1 and arc-shaped guide rail 2.
The working principle and process for using of the utility model: before osteotomy, being clamped with the splenial bone at 1 both ends of sliding rail pincers need to be truncated
Long bone both ends, then rotating adjusting nut 7, the left caliper 3 and right caliper body 4 for clamping splenial bone collapse and lock firm long bone.Lock jail
The preceding spacing pre-adjusted between both ends splenial bone pincers, guarantees osteotomy distance.When adjusting, pass through the U-shaped fork at 2 both ends of arc-shaped guide rail
9 move along sliding rail 1, referring to the graduation mark on sliding rail 1 when mobile, so as to accurate adjustable range, screw after distance adjusting is satisfied U-shaped
Limit screw 10 on fork 9 is the distance between two splenial bone pincers of lockable.
When osteotomy, the bone of certain length is truncated from the long bone between two splenial bone pincers with goose saw, long bone, which breaks, at this time is
Two sections, but be still fixedly secured by two splenial bone pincers.At this point, unlock limit screw 10, makes long by two sections on two splenial bone pincers
Bone is drawn close.If need to rotate the long bone on one of splenial bone pincers at this time, the lock-screw 8.2 on sliding lock 8 is unclamped, makes to press from both sides
Bone forceps is rotated around arc-shaped guide rail 2, finally realizes the long bone rotation on splenial bone pincers.
Therefore, two splenial bones pincers of the utility model can rotate, art along sliding rail transverse shifting around arc-shaped guide rail
In convenient for the femur after two sections of truncations is fixed on a suitable position, and be provided on sliding rail and arc-shaped guide rail
Graduation mark, the moving distance and rotation angle of splenial bone pincers can be controlled accurately, not only assist in precise measurement osteotomy distance, also
Two sections of femurs after being capable of fixing truncation, are easily installed type femoral bone end prosthesis, facilitate the instrument of the control femur broken ends of fractured bone, are wanted with meeting operation
It asks.
