Description
Technical Field
The utility model relates to a shin bone operation technical field, concretely relates to fixing device is corrected to miniature shin bone condyle.
Background
Giebel slotted steel plates were successfully used in clinical tibial osteosynthesis since 1979. The operation adopts the proximal tibia osteotomy, removes a wedge-shaped bone block at the same time, retains a little contralateral bone, is in a hinge shape, the two osteotomy surfaces are involuted, a groove-type steel plate is inserted into the proximal osteotomy end, and two cortical screws are screwed into the cortex of the contralateral distal bone. The screws are tightened to pressurize the osteotomy surfaces to form pressurized internal fixation.
In early cases, it was continuously discovered that the angle of screwing in the screw was smaller than the angle designed before the operation, so that the ideal therapeutic effect could not be achieved.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the above problem, a fixing device is corrected to miniature shin bone condyle is provided.
The utility model adopts the technical proposal that: a mini tibial condyle orthotic fixation device comprising: a slotted plate and a screw, wherein the slotted plate is provided with a slot plate and a screw,
the groove plate includes: a first connecting plate and a second connecting plate,
the top end surface of the first connecting plate is provided with a long groove,
one end of the first connecting plate is vertically and fixedly connected with the top of one side of the second connecting plate,
the second connecting plate is provided with a screw hole,
the screw is mounted in the screw hole.
Further, the long groove is a semicircular groove.
Still further, the screw hole is provided with 2 at least, and inwards inclines to set up on the second connecting plate, and correspondingly, the screw is provided with 2.
Furthermore, the top of the joint of the first connecting plate and the second connecting plate is in a chamfer design.
Further, the other end of the first connecting plate is in a tapered structure.
The utility model has the advantages that:
1. by providing a wider elongated slot in the first linkage plate, a more stable result is achieved when it is inserted into the proximal bony block.
2. The design of the inclined plane at the far end of the slotted plate is consistent with the structure on the guide seat chisel, so that the slotted steel plate is easy to drive. The stable internal fixation greatly shortens the rehabilitation time of the patient.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Referring to fig. 1-3, as shown in fig. 1-3, a mini tibial condyle corrective fixation device includes: a slotted plate 1 and a screw 2,
the groove plate 1 comprises: a first connecting plate and a second connecting plate,
the top end surface of the first connecting plate is provided with a long groove,
one end of the first connecting plate is vertically and fixedly connected with the top of one side of the second connecting plate,
the second connecting plate is provided with a screw hole,
the screw 2 is mounted in the screw hole.
It should be noted that the main inventive point of the present invention is that, firstly, the first connecting plate is provided with a wider slot, so that when it is inserted into the bone block on the proximal joint side, a more stable effect can be achieved; secondly, the tail end of the first connecting plate is set to be in a conical structure consistent with the structure on the guide seat chisel, so that the driving of the groove type steel plate is easier.
In an embodiment of the present invention, the elongated slot is a semicircular slot.
Wherein, the semicircular groove is favorable for the stability of the groove plate after being attached to the bone.
The utility model discloses an in the embodiment, the screw hole is equipped with 2 at least, and the leanin setting is in on the second connecting plate, it is corresponding, screw 2 is equipped with 2.
In an embodiment of the present invention, the first connecting plate and the top of the second connecting plate junction are designed to be chamfered.
In an embodiment of the present invention, the other end of the first connecting plate is a tapered structure.
It should be noted that the bevel design (taper configuration) of the distal end of the first link plate is consistent with the configuration of the guide chisel, which makes driving the channel steel plate easier. The stable internal fixation greatly shortens the rehabilitation time of the patient.
Preoperative preparation: regularly shooting X-ray films, including a knee joint positive side position, a patella axial position and a positive position film of a lower limb full-length standing position;
1. first, a weight line is drawn: drawing with a pencil from the center of the femoral head to the center of the ankle acupoint on an X-ray film;
2. the malformation angle is alpha, the line connecting the knee joint midpoint and the ankle point midpoint is made, and the intersection angle with the load line is alpha. The midpoint of the knee joint is the center of the femoral condyle tangent.
3. The angle to be corrected is beta. Correcting deformities of the femur and tibia, respectively. It is necessary to identify the site of the primary cause of the deformity.
4. The distance between the osteotomy line and the joint surface is 2cm, and the actual osteotomy angle is 3-4 degrees larger than the design angle.
5. Cut along the intended osteotomy line.
6. The upper and lower stencils are rotated to be matched and fixed by transparent adhesive tape.
7. The built-in objects are drawn, and the malformed angle and the correcting angle, the size of the edge of the osteotomy block and the length of the slotted steel plate are noted. The whole process can be repeated
8. The position of the weight line on the last stencil is checked.
The utility model provides a miniature tibia condyle correcting and fixing device, when in use, the proximal tibia is cut, a wedge-shaped bone block is removed at the same time, a little opposite side bone is reserved, the shape of a hinge is formed, the two bone sections are oppositely closed,
the first connector plate is then inserted into the proximal end of the osteotomy, two cortical screws are screwed into the opposite distal cortical bone through the screw holes, and the screws are tightened to compress the osteotomy surfaces together, resulting in compression internal fixation.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
