Abstract
The invention discloses a device for positioning the center of a femoral head in a high tibial osteotomy, which is characterized in that: the X-ray visible round sphere comprises a round sphere which can be seen through by X-rays, wherein two crossed concentric iron rings are wound on the round sphere, and a bulge is arranged at one crossed position of the two concentric iron rings. The invention has the advantages that two circles of concentric iron rings are wound outside the perspective ball, the protrusion is arranged at the intersection of the two circles of concentric iron rings, the center point of the femoral head can be accurately positioned during perspective conveniently, the center point is just positioned at the protrusion position, repeated perspective is not needed in an operation, the center position of the femoral head can be accurately positioned only by touching the protrusion position of the ball, the times of perspective of doctors and patients in the operation are reduced, and the operation time is shortened.
Description
Technical Field
The invention relates to a device for positioning the center of a femoral head in a high tibial osteotomy.
Background
The high tibial osteotomy mainly aims at knee joint inner side unicompartmental osteoarthritis, aims to correct the mechanical axis of lower limbs by osteotomy, correct the varus of the proximal end of the tibia into slight valgus, relieve the pressure born by the inner compartment of the knee joint, relieve the symptoms of patients, avoid the damaged cartilage from further damage, and delay or avoid the total knee joint replacement operation. The femoral head center has no locatable mark on the body surface, so that the femoral head center needs to be positioned by repeated fluoroscopy to determine the force line in the operation, the positioning mode prolongs the operation time, increases the fluoroscopy times of doctors and patients in the operation, and is not favorable for the operation effect and the recovery condition of patients.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a device for positioning the center of a femoral head in a high tibial osteotomy.
The technical scheme adopted by the invention for solving the technical problems is as follows:
a device for positioning the center of a femoral head in a high tibial osteotomy is characterized in that: the X-ray visible round sphere comprises a round sphere which can be seen through by X-rays, wherein two crossed concentric iron rings are wound on the round sphere, and a bulge is arranged at one crossed position of the two concentric iron rings.
In another preferred embodiment, the planes of the two concentric iron rings are perpendicular to each other.
In another preferred embodiment, the outer surface of the round ball is provided with two circles of grooves corresponding to the two crossed concentric iron rings, and the iron rings are embedded into the grooves.
In another preferred embodiment, the two intersecting concentric rings and the protrusion are wound from the same wire.
The invention has the advantages that two circles of concentric iron rings are wound outside the perspective ball, the protrusion is arranged at the intersection of the two circles of concentric iron rings, the center point of the femoral head can be accurately positioned during perspective conveniently, the center point is just positioned at the protrusion position, repeated perspective is not needed in an operation, the center position of the femoral head can be accurately positioned only by touching the protrusion position of the ball, the times of perspective of doctors and patients in the operation are reduced, and the operation time is shortened.
The invention is further explained in detail with the accompanying drawings and the embodiments; however, the device for centering the femoral head for tibial high-level osteotomy of the present invention is not limited to the embodiment.

FIG. 3 is a schematic diagram of a ball according to a preferred embodiment of the invention.
Fig. 4 is a perspective view of the femoral head center positioning performed in accordance with the preferred embodiment of the present invention.
FIG. 5 is a state diagram of the preferred embodiment of the present invention.
Detailed Description
In the embodiment, referring to fig. 1 and 2, the device for positioning the center of the femoral head in the tibial high-level osteotomy of the present invention comprises a spherical ball 1 which can be seen through by X-ray, wherein two crossed concentric iron rings 2 and 3 are wound on the spherical ball 1, and a protrusion 4 is arranged at one of the intersections of the two concentric iron rings 2 and 3.
Wherein, the planes of the two concentric circles 2 and 3 are perpendicular to each other.
Referring to fig. 3, the outer surface of the round ball 1 is provided with two grooves 11 and 12 corresponding to the two crossed concentric iron rings 2 and 3, and the iron rings 2 and 3 are respectively embedded in the grooves 11 and 12.
The two concentric iron rings 2 and 3 and the protrusion 4 are formed by winding the same iron wire.
Referring to fig. 4 and 5, when the positioning device of the invention is used for femoral head positioning, the center point of the femoral head can be positioned in a perspective manner before surgery, the protrusion 4 is just positioned at the center point of the femoral head, the device is fixed by using an adhesive tape, and accurate positioning can be realized only by touching the protrusion 4 in the surgery.
The above embodiments are merely provided to further illustrate the device for positioning the center of a femoral head for a tibial high osteotomy of the present invention, but the present invention is not limited to the embodiments, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention fall within the protection scope of the technical solution of the present invention.
