Description
Technical field
The present invention relates to a kind of long bone osteotomy device, belong to technical field of medical instruments.
Background technology
Bone surgery usually needs to carry out osteotomy in art, especially for hip dysplasia disease hip joint height
Dislocate patient, be expert at replacement of total hip when, it is necessary to carry out Subtrochanteric osteotomy, to shorten femur length, reduce femur head height
Degree, is easy to back include acetabular fossa, the process is higher to the precise requirements of Subtrochanteric osteotomy length, while for ease of installing femur
Need the femur after two sections are blocked to be fixed on a suitable position in handle prosthese, art, and typically pass through art in the prior art
After middle rough measure osteotomy length, section upper and lower ends bone section is clamped with share-holding pincers by assistant respectively, is then entered in art with goose saw
Row osteotomy.Osteotomy has the following disadvantages in this way：1st, need that operative site soft tissue is carried out fully to expose, increase wound
Wound；2nd, the length in osteotomy to osteotomy is not easy to accurately to be measured；3rd, after osteotomy, broken ends of fractured bone bone needs assistant using more energetically
The stable position needed in operating doctor of amount, it is difficult that easy fatigue causes broken ends of fractured bone bone pairing to reset, and produces broken ends of fractured bone rotation or misplaces
Pairing；4th, art area needs more apparatus to help the exposed osteotomy broken ends of fractured bone of operating, and takes operating doctor operating space to influence operator to cure
It is raw to carry out accurate osteotomy, osteotomy surface may be caused to influence the good pairing of osteotomy surface into diagonal.Accordingly, it would be desirable to which one can help accurate
Two sections of femurs that measurement osteotomy distance can be fixed after blocking again, while being easy to control the apparatus of the femur broken ends of fractured bone, are required with meeting operation.

Embodiment
In order that the object, technical solutions and advantages of the present invention are clearer, with reference to the accompanying drawings and examples to this hair
It is bright to be described in further detail.
9th, embodiments of the invention：As shown in Figures 1 and 2, including two parallel set the structural representation of long bone osteotomy device
The slide rail 1 put, two arc-shaped guide rails 2 are symmetrically provided with the two ends of two one slide rails 1, and the two ends of the arc-shaped guide rail 2 are set
There is U-shaped fork 9, arc-shaped guide rail 2 is slidably connected with two one slide rails 1 simultaneously by the U-shaped fork 9 at two ends, the length of the arc-shaped guide rail 2
The chute 11 being provided through on direction, limit screw 10 is connected to U-shaped fork 9 from the side of U-shaped fork 9 through the rear thread of chute 11
Opposite side on；Two splenial bone pincers are symmetrically provided with two arc-shaped guide rails 2, the splenial bone pincers include a symmetrically arranged left side
The clamp handle of caliper 3 and right caliper body 4, left caliper 3 and right caliper body 4 passes through sliding lock 8 by the hinge connection of rotating shaft 5, the lower end of right caliper body 4
It is slidably connected with arc-shaped guide rail 2, the sliding lock 8 includes the slip cap 8.1 for being fixedly connected on the lower end of right caliper body 4, in arc-shaped guide rail 2
Pass through and be slidably connected with slip cap 8.1 out of slip cap 8.1, lock-screw 8.2 is provided with the side wall of slip cap 8.1.
Be connected with adjusting screw 6 in the inboard hinge of right caliper body 4, adjusting screw 6 through after the through hole 12 of the lower end of left caliper 3 with regulation spiral shell
Mother 7 connects.The center of arc of the arc-shaped guide rail 2 and the jaw center that splenial bone is clamped are concentric.The left caliper 3 and right caliper body 4
Jaw section is arc-shaped structure, is easy to clamp femur.Anti-slip veins are provided with the inside of the jaw of the left caliper 3 and right caliper body 4
13.Graduation mark is provided with the slide rail 1 and arc-shaped guide rail 2.
The present invention operation principle and use flow：Before osteotomy, the long bone that need to be blocked is clamped with the splenial bone pincers at the two ends of slide rail 1
Two ends, then rotating adjusting nut 7, make left caliper 3 and right caliper body 4 that splenial bone is clamped draw in and lock firm long bone.Can before lock jail
Pre-adjust the spacing between two ends splenial bone pincers, it is ensured that osteotomy distance.During regulation, pass through the edge of U-shaped fork 9 at the two ends of arc-shaped guide rail 2
Slide rail 1 is moved, with reference to the graduation mark on slide rail 1 when mobile, so as to accurate adjustment distance, and U-shaped fork 9 is screwed after distance regulation is satisfied
On limit screw 10 be the distance between two splenial bones of lockable pincers.
During osteotomy, the bone of certain length is blocked from the long bone between two splenial bone pincers with goose saw, now long bone, which breaks, is
Two sections, but be still fixedly secured by two splenial bone pincers.Now, limit screw 10 is unlocked, is made long by two sections on two splenial bone pincers
Bone is drawn close.If now need to rotate the long bone on one of splenial bone pincers, the lock-screw 8.2 on sliding lock 8 is unclamped, makes folder
Bone forceps rotates around arc-shaped guide rail 2, finally realizes the long bone rotation on splenial bone pincers.
Therefore, two splenial bones of the invention pincers can be rotated, in art just around arc-shaped guide rail again along slide rail transverse shifting
Femur after two sections are blocked is fixed on a suitable position, and is provided with scale on slide rail and arc-shaped guide rail
Line, the displacement and the anglec of rotation of splenial bone pincers can be controlled accurately, not only assist in accurate measurement osteotomy distance, moreover it is possible to Gu
Surely two sections of femurs after blocking, are easily installed type femoral bone end prosthesis, and the apparatus of the convenient control femur broken ends of fractured bone is required with meeting operation.
