A kind of individuation femur multiaspect osteotomy external member, comprises the body with positive and negative; Its construction features is, described body have front ankle bone cutting groove for carrying out osteotomy to preartis, for postartis is carried out osteotomy postartis osteotomy groove, for carrying out the front bevel osteotomy groove of osteotomy and the back bevel osteotomy groove for carrying out osteotomy to femur back bevel to femur front bevel; Described front bevel osteotomy groove and back bevel osteotomy groove are arranged between front ankle bone cutting groove and postartis osteotomy groove; The positive and negative of described front ankle bone cutting groove, postartis osteotomy groove, front bevel osteotomy groove and all through body of back bevel osteotomy groove; Whether described body end has for gap of determining to go down on one's knees is the clearance balancing machine installing hole of rectangle.
Thus, by front ankle bone cutting groove, postartis osteotomy groove, front bevel osteotomy groove and back bevel osteotomy groove, osteotomy saw blade can complete the osteotomy to inclined-plane before and after front and back condyle, femur.
According to embodiment of the present utility model, can also do further to optimize to this utility model, the technical scheme below for being formed after optimization:
Described clearance balancing machine installing hole is built with clearance balancing machine, and this clearance balancing machine comprises horizontal substrate, the outward extending guide post of the basal surface perpendicular to horizontal substrate; Described horizontal substrate has power handle, this power handle has at least one for verifying the line of force hole of the overall line of force of lower limb after osteotomy; Described guide post is contained in clearance balancing machine installing hole and also can moves back and forth along clearance balancing machine installing hole.Described femur multiaspect cuts plate and clearance balancing machine can with guide post upper and lower vertical sliding motion in installing hole with the use of, horizontal substrate, can not move left and right or movable, thus conveniently determines the gap of going down on one's knees of rectangle.Line of force bar is installed for verifying in described line of force hole, determines the accuracy of osteotomy.
Preferably, described clearance balancing machine installing hole is circular hole, and described guide post is cylindrical bar.
Further, described body is provided with multiple locating hole, fixing for guide plate.
Conveniently determine the femur outward turning angle of individuation, the line of multiple locating hole is parallel to the interior lateral epicondyle line of femur (i.e. logical condyle axle).
Described body is provided with the observation port of the positive and negative of through body, can conveniently observe guide plate lay whether accurate.
Above structure, individuation femur multiaspect osteotomy external member of the present utility model comprises femur multiaspect osteotomy plate and clearance balancing machine, and described femur multiaspect osteotomy plate comprises body, condyle osteotomy groove, inclined-plane osteotomy groove, locating hole and installing hole.Described condyle osteotomy groove comprises front ankle bone cutting groove and postartis osteotomy groove, and described inclined-plane osteotomy groove comprises front bevel osteotomy groove and back bevel osteotomy groove, and described mounting hole site is in described body center and perpendicular to this long axis of body.Described clearance balancing machine comprises horizontal substrate and cylindrical bar, and cylindrical bar is vertically positioned at horizontal substrate central authorities, and the size of cylindrical bar and the installing hole of above-mentioned femur multiaspect osteotomy external member match, power handle horizontal substrate having give prominence to forward, strong string holes on power handle.
Compared with prior art, the beneficial effects of the utility model are: this utility model adopts gap equilibrium principle to carry out the osteotomy of distal femur multiple, guaranteeing that knee joint stretches gap of going down on one's knees is rectangle, makes distal femur outward turning osteotomy angle individuation simultaneously, more meets the personal feature of patient.
Below in conjunction with drawings and Examples, this utility model is further elaborated.
Accompanying drawing explanation
Fig. 1 is the Facad structure schematic diagram of a kind of embodiment of this utility model;
Fig. 2 is the rear view of Fig. 1;
Fig. 3 is the front end face schematic diagram of Fig. 1;
Fig. 4 is the structural representation of clearance balancing machine described in the utility model.
Detailed description of the invention
The representative instance embodying this utility model feature & benefits will describe in detail in the following description.Be understood that this utility model can have various changes in different instances, it neither departs from scope of the present utility model, and explanation wherein and accompanying drawing are the use when explain in itself, and is not used to limit this utility model.
As shown in Figure 1, Figure 2 and Figure 3, the femur multiaspect osteotomy plate in this utility model comprises body 1, front ankle bone cutting groove 21 and postartis osteotomy groove 22, front bevel osteotomy groove 31 and back bevel osteotomy groove 32, locating hole 4 and installing hole 5 to a kind of individuation femur multiaspect osteotomy external member.Front ankle bone cutting groove and postartis osteotomy groove are respectively used to the osteotomy of preartis and postartis.Front bevel osteotomy groove and back bevel osteotomy groove are respectively used to the osteotomy of front bevel and back bevel.Body 1 has the observation port 10,11 of its positive and negative through.
As shown in Figure 3, described clearance balancing machine comprises horizontal substrate 6 and cylindrical bar 7, and cylindrical bar 7 is vertically positioned at horizontal substrate 6 central authorities.The power handle 8 that horizontal substrate 6 central authorities have one to give prominence to forward, strong string holes 9 on power handle 8.
Be opened in the clearance balancing machine installing hole 5 of body 1 end face for laying cylindrical bar 7, femur multiaspect osteotomy plate is connected by installing hole 5 and cylindrical bar 7 with clearance balancing machine, and body 1 can slide up and down along cylindrical bar 7, can not move left and right.
As Figure 1-4, in the present embodiment, horizontal substrate 6 has been positioned on the proximal tibia osteotomy surface of osteotomy, body 1 is connected on cylindrical bar 7 by installing hole 5, body 1 is placed on the femoral bone pulley face after distal femur osteotomy again, body 1 adjusts the size in gap of going down on one's knees by the slip on cylindrical bar 7, makes it equal with stretching knee joint clearance distance.Outward turning osteotomy angle considers gap balance and outward turning locating hole reserved before.Staple is squeezed into distal femur surface of bone by locating hole 4 be fixed.Osteotomy saw blade carries out the osteotomy of preartis, postartis, front bevel and back bevel respectively by front ankle bone cutting groove 21, postartis osteotomy groove 22, front bevel osteotomy groove 31 and back bevel osteotomy groove 32.Cylindrical bar 7 and installing hole 5 match, and for determining to go down on one's knees, whether gap is rectangle.Power handle 8 and line of force hole 9 can use line of force bar to carry out the assessment of the overall line of force of lower limb.
The technical solution of the utility model is disclosed as above by preferred embodiment.The change that those skilled in the art do when should recognize the scope and spirit of the present utility model disclosed in the claim do not departed from appended by this utility model and retouching, within the protection domain all belonging to claim of the present utility model.
