Description
Technical field
The present invention relates to the field of medical instrument technology, and in particular to a kind of osteotomy guide plate.
Background technique
In existing orthopaedic medical treatment method, it can be corrected and be treated by doing bone-culting operation to skeletal abnormalities position,
Extra bone tissue can be cut off, one section of prosthese is filled up after bone can also being cut off, final result is provided to keep bone long
Degree and shape reach pre-provisioning request.
And be related to being required to osteotomy in many operations of ankle and foot, Li such as Hallux turns up bone-culting operation, needs to carry out soft group
It knits to move in joint metatarsal osteotomy of loosening and be screwed again, to reach the purpose of orthopedic, fusion, but osteotomy is mostly according to doctor at present
Often there is osteotomy inaccuracy, situation not in place in raw personal experience, and foot bone is relatively small in addition, wants to osteotomy accuracy
It asks relatively high, therefore, it is necessary to design targetedly guide plate, avoids the uncontrollability and cutting ruler of doctor's hand operation
Very little and angle alternative.The guide plate for the operation of first metatarsal bone osteotomy of distal more existing at present, but there is presently no
It is exclusively used in the guide plate of first metatarsal bone backbone osteotomy.
Summary of the invention
Present invention aims to overcome that the shortcomings that prior art and deficiency, provide a kind of for first metatarsal bone backbone osteotomy
Osteotomy guide plate, be conducive to the accuracy for improving first metatarsal bone backbone bone-culting operation, and reach better surgical effect.
To achieve the above object, The technical solution adopted by the invention is as follows:
A kind of osteotomy guide plate, including plate, the plate are equipped with notch, and the notch includes long side and short side, described
The long side of notch and the length direction of plate are parallel, and the long side and short side of the notch at an angle to each other is 45 degree, the plate
Kirschner wire fixation hole is respectively equipped in the long side and short side of notch；The plate the long side of notch be provided with be equipped with
Two long sides of the quadrilateral hole that notch is connected, the quadrilateral hole are parallel with the short side of notch respectively.
From the foregoing, it will be observed that in the use of the present invention, the present invention is fixed on first by Kirschner wire fixation hole using Kirschner wire
On metatarsal, a parallel edges of the quadrilateral hole as z font at this time, another parallel edges of the short side of notch as z font, and
Connection side of the long side of notch as two parallel edges of z font, as then by thin osteotomy saw blade insertion quadrilateral hole with
In the z font formed between notch, and desired Z-shaped slot is sawed out on first metatarsal bone backbone along z font, to avoid sawing out
Z-shaped slot there is deviation, compared to the Z-shaped slot that doctor saws out by rule of thumb, can achieve better surgical effect through the invention, have
Conducive to the accuracy for improving bone-culting operation.
In conclusion the present invention utilizes the z font formed between quadrilateral hole and notch and along z font in first metatarsal bone
Desired Z-shaped slot is sawed out on backbone, so that the Z-shaped slot sawed out be avoided deviation occur, compared to the Z-shaped slot that doctor saws out by rule of thumb,
It can achieve better surgical effect through the invention, be conducive to the accuracy for improving bone-culting operation.
As an improvement of the present invention, the plate is equipped with several Kirschner wire fixation holes in the long side of notch, if
Long side length direction equidistantly distributed of the dry Kirschner wire fixation hole along notch.
Further, described several Kirschner wire fixation hole adjacent spacings in notch long side are 4~5mm.
As an improvement of the present invention, the length of the notch short side is 3~5mm, and the slab-thickness is 3~5mm.
Compared with prior art, the invention has the following advantages that
The present invention utilizes the z font formed between quadrilateral hole and notch and saws on first metatarsal bone backbone along z font
Desired Z-shaped slot out, to avoid the Z-shaped slot sawed out from deviation occur, compared to the Z-shaped slot that doctor saws out by rule of thumb, by this hair
It is bright to can achieve better surgical effect, be conducive to the accuracy for improving bone-culting operation.
Detailed description of the invention
Fig. 1 is the schematic diagram of osteotomy guide plate of the present invention.

Embodiment
Referring to FIG. 1, a kind of osteotomy guide plate, including plate 10, the plate 10 are equipped with notch 20, the notch 20 is wrapped
Long side 21 and short side 22 are included, the long side 21 of the notch 20 is parallel with the length direction of plate 10, the long side of the notch 20
21 with short side 22 it is at an angle to each other be 45 degree, the plate 10 is respectively equipped with Kirschner wire fixation in the long side and short side of notch 20
Hole 40；
The plate 10 is provided in the long side of notch 20 and is equipped with the quadrilateral hole 30 being connected with notch, four side
Two long sides in shape hole 30 are parallel with the short side 22 of notch 20 respectively.
From the foregoing, it will be observed that in the use of the present invention, the present invention is fixed on first by Kirschner wire fixation hole using Kirschner wire
On metatarsal, a parallel edges of the quadrilateral hole as z font at this time, another parallel edges of the short side of notch as z font, and
Connection side of the long side of notch as two parallel edges of z font, as then by thin osteotomy saw blade insertion quadrilateral hole with
In the z font formed between notch, and desired Z-shaped slot is sawed out on first metatarsal bone backbone along z font, to avoid sawing out
Z-shaped slot there is deviation, compared to the Z-shaped slot that doctor saws out by rule of thumb, can achieve better surgical effect through the invention, have
Conducive to the accuracy for improving bone-culting operation.
In conclusion the present invention utilizes the z font formed between quadrilateral hole and notch and along z font in first metatarsal bone
Desired Z-shaped slot is sawed out on backbone, so that the Z-shaped slot sawed out be avoided deviation occur, compared to the Z-shaped slot that doctor saws out by rule of thumb,
It can achieve better surgical effect through the invention, be conducive to the accuracy for improving bone-culting operation.
In the present embodiment, the plate 10 is equipped with several Kirschner wire fixation holes 40 in the long side of notch 20, several
A Kirschner wire fixation hole 40 is distributed along 21 equal spacing in length direction of long side of notch 20.If moreover, described in notch long side
Dry 40 adjacent spacing of Kirschner wire fixation hole is 4~5mm.
In the present embodiment, the length of the notch short side 22 is 3~5mm, and the plate 10 is with a thickness of 3~5mm.Osteotomy
When guide plate is fixed on the first metatarsal bone backbone of patient, osteotomy guide plate and first metatarsal bone backbone are to be in close contact, and too thick cuts
Bone conduction plate is easy to increase operating difficulty, and too thin osteotomy guide plate is unfavorable for processing.
The above embodiment is a preferred embodiment of the present invention, but embodiments of the present invention are not by above-described embodiment
