Description
Technical field
The present invention relates to the field of medical instrument technology, and in particular to a kind of improvement guide plate for bone-culting operation.
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 first metatarsal bone distal end and backbone bone-culting operation more existing at present, but at present
Guide plate there is also some problems, for example existing guide plate is not in full conformity with clinical application, for first metatarsal bone backbone osteotomy
Guide plate structure is single, can not adjust osteotomy distance and cutting angle etc..
Summary of the invention
Present invention aims to overcome that the shortcomings that prior art and insufficient, provides a kind of improvement for bone-culting operation and lead
Plate is conducive to the accuracy for improving bone-culting operation, while being adjustable osteotomy distance, applied widely.
To achieve the above object, The technical solution adopted by the invention is as follows:
A kind of improvement guide plate for bone-culting operation, including plate, the symmetrical two sides of the one of the plate are respectively to same
Direction bending and form the linkage section for being connected with first metatarsal bone, the plate be equipped with notch, notch include long side and
Short side, the long side of notch and the length direction of linkage section are parallel, and the long side and short side of notch at an angle to each other is 45 degree, described flat
Plate is equipped with several slots for being connected with notch in the long side of notch, two long sides of slot respectively with notch
Short side is parallel, several slots are parallel and are arranged at equal intervals；Linkage section is equipped with connecting hole.
From the foregoing, it will be observed that in the use of the present invention, the present invention is fixed on first metatarsal bone by connecting hole using steel nail, this
When a single parallel edges of the slot as z font of the present invention, 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 that thin osteotomy saw blade insertion is single rectangular
In the z font formed between shape hole and notch, it can according to need operation and need several slots selected in long side
One of them, to obtain having the z fonts of different connection edge lengths, and along z font on first metatarsal bone backbone the phase of sawing out
The Z-shaped slot of prestige, compared to the Z-shaped slot that doctor saws out by rule of thumb, through the invention may be used so that the Z-shaped slot sawed out be avoided deviation occur
To reach better surgical effect, be conducive to the accuracy for improving bone-culting operation, while being adjustable osteotomy distance, the scope of application
Extensively.
In conclusion the present invention using multiple slots respectively from the different z font of notch composition size, to realize
It can according to need operation and need to adjust osteotomy distance；In addition, using the z font of slot and notch composition and along z word
Type saws out desired Z-shaped slot on first metatarsal bone backbone, to avoid the Z-shaped slot sawed out from deviation occur, by rule of thumb compared to doctor
The Z-shaped slot sawed out, 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 cross section of the linkage section is inflexed arcwall face.
As an improvement of the present invention, a long side of the slot, notch short side set respectively in upper half side-view
There is upper instrument bevel, another long side, the long side of notch of the slot are equipped with lower instrument bevel in lower half side-view respectively, on
Instrument bevel and under to cut inclined-plane be respectively 15 degree with the angle of vertical face.
As an improvement of the present invention, the quantity of the slot is 3.
As an improvement of the present invention, the equal length of two long sides of the slot and be 3~5mm, the phase
Spacing between adjacent slot is 4~6mm.
As an improvement of the present invention, the slab-thickness is 3~5mm.
Compared with prior art, the invention has the following advantages that
The present invention using multiple slots respectively from the different z font of notch composition size, so that realizing can basis
It needs to perform the operation and needs to adjust osteotomy distance；
In addition, the z font that is formed using slot with notch and sawing out on first metatarsal bone backbone along z font it is expected
Z-shaped slot, through the invention can be with compared to the Z-shaped slot that doctor saws out by rule of thumb so that the Z-shaped slot sawed out be avoided deviation occur
Reach better surgical effect, is conducive to the accuracy for improving bone-culting operation.
