Abstract
The utility model relates to a minimally-invasive femur near-end contact-restricting locking type dual safety compound bone plate. The bone plate comprises a bone plate head matching the outer side surface of a femur trochanter and a bone plate connecting rod matching the outer side of a femur bone. The bone plate head is connected on the top of the bone plate connecting rod which is provided with multiple locking holes. Three threaded locking holes which are arranged in a triangular way are equipped on the bone plate head. Spherical pulling nails locking the femur trochanter, a femur neck and a ball end penetrate at least one threaded locking hole. By adopting the spherical pulling nails and locking pulling nails to match the femur conditions, tightening, positioning and locking of the compound bone plate in the utility model with the femur are achieved. Meanwhile, the compound bone plate which is convenient to install and has locking stability is conducive to accurate resetting. Furthermore, the compound bone plate which casts no influence on the regrowth of the femur medullary cavities and fractured bones has excellent treatment effects.
Description
Technical field
This utility model relates to the orthopaedic medical treatment technical field, is the locking-typed dual safe combined type blade plate of a kind of Wicresoft near end of thighbone limited contact specifically.
Background technology
Along with the aging of China's population and the loose trend that linearly rises of fracture of middle-aged and elderly people; Interrelated data shows; The domestic average life span has reached 73 years old, and person in middle and old age's activity reduces gradually, also is to cause one of reason that person in middle and old age's osteoporosis sickness rate increases gradually; The patient age that hip (refer between femoral bone tuberosity and the neck of femur) fracture of bibliographical information more than 90% arranged is all at over-65s, and wherein 3/4 is the women.Traditional treatment is main with dynamic coxa; Be DHS compressive sleeve gooseneck boom nail, though its therapeutic effect get the nod already, comparatively complicated when clinical installation; And it is too big to the skeleton damage; Neck of femur and bulb standing part are a pulling force nail, and relative stability is poor, and the phenomenon of clinical practice generation product fracture is more; Only produce pulling force after the pulling force nail is installed, will reach proper reset during art and have certain degree of difficulty, add that blade plate contacts very little with bone surface, it is incorrect to cause resetting, and fixing unstable, therapeutic effect is poor; The head skirt diameter of DHS sleeve gooseneck boom nail is 13mm; Length 25～30mm, punching is bigger between the skeleton tuberosity when mounted, installs back gooseneck boom nail sleeve and basically intertrochanteric pulp cavity is stopped up; Stoped the circulation of pulp cavity inner blood and bone marrow; Influenced fracture regrowth speed equally, prolonged healing time, it is painful to have increased sufferer.
The utility model content
The purpose of this utility model provides a kind of simple in structure, and is easy for installation, and locking is stable, helps proper reset, do not influence femoral bone cavitas medullaris and fracture regrowth, the locking-typed dual safe combined type blade plate of Wicresoft's near end of thighbone limited contact that therapeutic effect is good.
In order to achieve the above object; The technical scheme that this utility model adopts is: the locking-typed dual safe combined type blade plate of a kind of Wicresoft near end of thighbone limited contact; Comprise and the blade plate head of femoral bone tuberosity lateral surface coupling and the blade plate connecting rod that matees with the femoral shaft bone outside; The blade plate head is connected in blade plate connecting rod top; The blade plate connecting rod is provided with a plurality of lock holes, is characterized in that said blade plate head is provided with three thread lock holes that are triangular row portion, is penetrated with the spherical pulling force nail that locks femoral bone tuberosity, neck of femur and bulb at least one the thread lock hole.
Said three thread lock holes are triangular row portion, and arbitrary thread lock hole is not all on same horizontal line.
Run through a spherical pulling force nail and two locking pulling force nails in said three thread lock holes.
Said spherical pulling force nail is in the thread lock hole in centre position on the vertical direction in three thread lock holes.
A plurality of lock holes on the said blade plate connecting rod include more than one locking and pressurizing hole.
With a thread lock hole of ball shape pulling force nail cross-under blade plate head, spherical pulling force nail is worn to the tuberosity bulb through neck of femur by the tuberosity outside, produces pulling force and can regulate the fracture clearance distance earlier; The other two thread lock holes of two lockings of reuse pulling force nail cross-under blade plate head; Two locking pulling force nails are worn to the tuberosity bulb through neck of femur by the tuberosity outside, play location, locking effect, and the butt joint of tuberosity fracture stablizes, is difficult for loosening; Help resetting accurately, indeformable; Use spherical pulling force nail or locking pulling force nail locking blade plate connecting rod then as required; The blade plate connecting rod uses spherical pulling force nail to cooperate the locking of locking and pressurizing hole with femoral shaft bone anastomosis; Misfitting the place uses locking pulling force nail to cooperate lock hole locking; Make blade plate connecting rod and fixed, the non-loosening of femoral shaft bone, life-time service does not have potential safety hazard.
This utility model adopts spherical pulling force nail and locking pulling force nail according to the use that is mixed of blade plate and the femur situation of coincideing, tension, location and the locking of realization blade plate and femur, and it is easy for installation; Locking is stable; Help proper reset, do not influence femoral bone cavitas medullaris and fracture regrowth, therapeutic effect is good.
