Description
Technical field
The invention belongs to medical instruments field, it is related to a kind of individuation closure osteotomy guide plate and its manufacturing method.
Background technique
Extremities joint or skeleton deformity generally require operative treatment after conservative therapy is invalid, and the pass of operative treatment
Key is the line of force of bone to be restored, and is allowed to meet normal appearance, keeps limb function to greatest extent to the greatest extent.When skeleton deformity, bone
Bone osteotomy precisely often determines operative effect, and osteotomy is divided into " V " closure osteotomy, and open two kinds of common sides of osteotomy at present
Formula, this needs to combine patient's topography, which kind of osteotomy mode disease feature selects.In short, after osteotomy, it can be accurate
Restore subjects bones' line of force, keep osteotomy surface smooth, fixed conducive to steel plate screw, healing is easy when osteotomy surface is larger.
Current bone-culting operation generally passes through the experience of surgical staff and the body surface dissection of patient carries out the auxiliary of Kirschner wire
Positioning is helped, is easy to appear and is not allowed because positioning, need the drawbacks of having an X-rayed repeatedly and reinserting Kirschner wire, and is had an X-rayed repeatedly, not only
It will lead in art and radiate, can also extend operating time；In addition, the experience of current osteotomy site and osteotomy length by surgical staff
Operation, osteotomy section configuration, the size that not can guarantee osteotomy part match, and surgical effect is bad, postoperative to be difficult to heal.
Summary of the invention
In view of this, being avoided the purpose of the present invention is to provide a kind of individuation closure osteotomy guide plate and its manufacturing method
Using traditional technology, the drawbacks of fully relying on surgical staff experience and patient body-surface dissection auxiliary positioning, osteotomy section is avoided to go out
Existing step, causes surgical effect bad, postoperative to be difficult to the problem of healing.

Bacterium prepares to use in art.
Specific surgical procedure is as follows: label notch first chooses osteotomy area skin notch, and sufficiently exposure needs osteotomy
Region.By osteotomy sur-face peeling periosteum, guide plate ontology 1 is placed on osteotomy position, the Kirschner wire of 2.0mm diameter is successively bored
Enter in the positioning through hole 12 of guide plate, be reliably fixed guide plate ontology 1, Kirschner wire is pierced in guidance through slot 11, C arm has an X-rayed x-ray inspection
It is suitable to look into determining osteotomy surface, is inserted into osteotomy saw blade and carries out osteotomy.Close up osteotomy section after osteotomy, selects steel plate screw solid
It is fixed.Terminating operation consent, it is suitable using C arm X machine confirmation screw length.Joint capsule, subcutaneous tissue are successively closed, whole notch make
It is closed, is then fixed using plaster slab, specific osteotomy process please refers to attached drawing, by leading with nylon suture interrupted suture
Plate ontology 1 is located on osteotomy position 3, the correct position and direction for guiding osteotomy saw blade, through cutting, the bone block that will need to remove
4 separate and take out from osteotomy position 3, and osteotomy saw blade cutting position should be aggregated in same vertex, and the shape of upper and lower two osteotomy section
Shape, size should keep almost the same.
What the present invention innovated designs a kind of individuation closure osteotomy guide plate, scanned using the CT scan or body surface of patient etc.
Mode obtains configuration of surface, according to preoperative plannings such as CT or X-rays, the best entry point of comprehensive descision Kirschner wire, by auxiliary
Software design goes out the guide plate ontology 1 being identical with patient's osteotomy position form, to easily determine the osteotomy of osteotomy saw blade
Position and the position location of guide plate ontology 1.Compared with traditional operation form, the invention avoids be easy using traditional technology
Now positioning is inaccurate, the drawbacks of perspective repeatedly, avoids postoperative osteotomy section size, shape difference, step occurs after closing up, cause
The drawback that junction fixing intensity is low, post-operative recovery is slow.Osteotomy guide plate in the present invention is prepared according to individual patients, operation
Preceding to be designed under computer software help, unique, guide plate is easy to use, does not influence to have an X-rayed in art, and the present invention
Also include the osteotomy site model 2 completely the same with patient legs' shape, guide plate ontology 1 can be cooperated to carry out operation in the preoperative and drilled
Practice, simulate surgical outcome, optimization 1 structure of guide plate ontology is returned to according to practice result, surgical procedures can be advanced optimized, into one
Step improves surgical effect, has certain directive function to the structural improvement of the medical auxiliary apparatus of similar operation.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of the technical program, should all be covered in the present invention
