Abstract
The invention discloses a double-track bone fracture plate for a minimally invasive surgery. The double-track bone fracture plate comprises a baseplate. The double-track bone fracture plate is characterized in that two tracks are arranged at the top side of the baseplate, through holes passing through the baseplate are arranged in the tracks, a sliding block is arranged on the tracks, and round holes passing through the sliding block are arranged on the sliding block. Further, the two tracks are deviated for a certain angle from the vertical line of the top side of the baseplate. With the adoption of the double-track bone fracture plate for the minimally invasive surgery, the adjustment to a fixing position can be achieved so as to be convenient for fixing. In addition, the round holes in the sliding block and the through holes in the baseplate are mutually matched, so that bolts are fixed on the bone fracture plate in the way of intersecting to form angle, and the sliding of the sliding block is used, so that a proper position is selected for fixing, the design overcomes the stress shielding caused by factors that the contraction forces of the bolts, the baseplate and bone surrounding muscle group are unbalanced; and meanwhile, multiple-plane locking fixing can be achieved, the control volume of the bolts is improved, the holding force is improved, so that the fixing of the bone fracture plate is stable so as to be in favor of the healing of a fracture.
Description
Technical field
The invention belongs to medical instruments field, specifically, relate to a kind of Minimally Invasive Surgery and use double rail type bone fracture plate.
Background technology
Fracture Minimally Invasive Surgery utilization microscope or high magnified glass amplify the surgical field of view operation that undergos surgery, and through as far as possible little skin incision execution " keyhole operation ", make the orthopaedics surgical operation implement efficacious therapy with the iatrogenic injury of minimum.At present, in this type operation, blade plate is must indispensable fixation device, adopts mostly that pressurized bone plate, bone splint plate etc. variously come in every shape, intimate blade plate, as fixation device.Though existing blade plate is to be fixed on fracture site by the Luoding; Solving strong fixing this difficult problem in varying degrees; But in the process of fracture site healing, these fixation devices exist the stress shielding problem, because can not shorten the healing time of fracture; Produce complication such as joint stiffness, osteoporosis simultaneously, checking has influenced rehabilitation and the wounded healthy of fracture.
Summary of the invention
The technical problem that the present invention will solve is to overcome above-mentioned defective, provide a kind of simple in structure, be convenient to adjust and effectively fixedly the Minimally Invasive Surgery of the fracture of all ages and classes section, the different conditions of the injury use double rail type bone fracture plate.
For addressing the above problem, the technical scheme that the present invention adopted is:
A kind of Minimally Invasive Surgery is used double rail type bone fracture plate, comprises substrate, and the cross section of substrate is an ellipse, it is characterized in that: the top side face of said substrate is provided with two tracks, is provided with the through hole that runs through substrate in the track; On the said track slide block is installed, slide block is provided with the circular hole that runs through slide block.
Say further:
Said two tracks are from the certain angle of top side face vertical line skew of substrate.
Further say:
Said track from the angle of the top side face vertical line of substrate skew between 8-12 °.
Be evenly distributed with three circular holes on the said slide block.
Number of through-holes in the said track be with slide block one to one.
The number of said through hole is six, and the number of corresponding slide block is six.
Further say:
The bottom side of said substrate is the anatomical shape of femur, to be attached to the surface of femur.
The bottom side of said substrate is the anatomical shape of tibia, to be attached to the surface of tibia.
Owing to adopted technique scheme, compared with prior art, the present invention is that a kind of Minimally Invasive Surgery is used double rail type bone fracture plate, can realize the adjustment of fixed position, is convenient to fix, can be effectively the fixing fracture of all ages and classes section, the different conditions of the injury.In addition, circular hole on the slide block and the through hole on the substrate cooperatively interact, and screw is fixed on the blade plate with the mode that is crossed as the angle; And utilize the slip of slide block, select suitable fixed-site, such design; Overcome the stress shielding that factors such as muscle group contractility around screw, substrate and the bone is unbalanced cause, simultaneously also can the locking of more than enough plane fixing, increase the volume of controlling of screw; Increase hold, thereby make the fixing more firm of blade plate, the healing that helps fracturing.
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described further simultaneously.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the present invention.
Among the figure: the 1-circular hole; The 2-slide block; The 3-through hole; The 4-track; The 5-substrate.
The specific embodiment
Embodiment:
Of Fig. 1, a kind of Minimally Invasive Surgery is used double rail type bone fracture plate, comprises substrate 5, and the cross section of substrate 5 is an ellipse, and in the present invention, the top side face of said substrate 5 is provided with two tracks 4, is provided with the through hole 3 that runs through substrate 5 in the track 4.Slide block 2 is installed on the track 4, and slide block 2 is provided with the circular hole 1 that runs through slide block.In the present invention, the quantity of circular hole and position, the quantity of through hole and position are because they both cooperatively interact, so the quantity of circular hole and through hole and position are all confirmed according to practical situation.
In the present embodiment, said two tracks 4 are from the certain angle of top side face vertical line skew of substrate 5.Situation according to reality is used sees that track 4 is best selection from the angle of the top side face vertical line skew of substrate 5 between 8-12 °.
In addition, in the present embodiment, being evenly distributed with three circular holes on the said slide block is a kind of most preferred embodiments, corresponding, the number of through-holes in the track be with slide block one to one.The number of said through hole is six, and the number of corresponding slide block is six.
In order to guarantee result of use, the bottom side of substrate is the anatomical shape of femur, to be attached to the surface of femur.The bottom side of substrate is the anatomical shape of tibia, to be attached to the surface of tibia.The bottom side of substrate also can be designed as the anatomical shape of other bone, just differs once more one to have enumerated.
The present invention is a kind of double rail type bone fracture plate, can realize the adjustment of fixed position, is convenient to fix, can be effectively the fixing fracture of all ages and classes section, the different conditions of the injury.In addition, circular hole on the slide block and the through hole on the substrate cooperatively interact, and screw is fixed on the blade plate with the mode that is crossed as the angle; And utilize the slip of slide block, select suitable fixed-site, such design; Overcome the stress shielding that factors such as muscle group contractility around screw, substrate and the bone is unbalanced cause, simultaneously also can the locking of more than enough plane fixing, increase the volume of controlling of screw; Increase hold, thereby make the fixing more firm of blade plate, the healing that helps fracturing.
The present invention is not limited to above-mentioned preferred implementation, and anyone should learn the structural change of under enlightenment of the present invention, making, and every have identical or akin technical scheme with the present invention, all belongs to protection scope of the present invention.
