Abstract
The invention relates to a minimally invasive proximal femoral limited-contact and locking double safety compound bone joining plate, which comprises a bone joining plate head matched with the outer side face of the femoral trochanter and a bone joining plate connecting rod matched with the outside of the femoral shaft; the bone joining plate head is connected with the top of the bone joining plate connecting rod; the bone joining plate connecting rod has a plurality of locking holes; the bone joining plate head has three threaded locking holes which are arranged in a regular tangle; and at least one of the threaded locking holes is run through by a spherical pull nail which locks the femoral trochanter, the femoral neck and the bulb. The spherical pull nail and a locking pull nail are used in mixed combination according to the matching condition of the bone joining plate and the femur, so the tensioning, positioning and locking of the bone joining plate and the femur are realized. The minimally invasive proximal femoral limited-contact and locking double safety compound bone joining plate can be installed conveniently and locked stably, is favorable for correct reduction, avoids influencing the femoral myelocavity and re-growth after fracture and achieves good treatment effect.
Description
Technical field
The present invention 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 restriction 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 be 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 Therapeutic Method is based on dynamic coxa, it is DHS compressive sleeve gooseneck boom nail, though its therapeutic effect gets the nod already, but it is 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, installing back gooseneck boom nail sleeve stops up intertrochanteric pulp cavity substantially, stoped the circulation of pulp cavity inner blood and bone marrow, influence fracture regrowth speed equally, prolonged healing time, increased the sufferer misery.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, easy for installation, locking is stable, helps proper reset, does 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 restriction contact that therapeutic effect is good.
In order to achieve the above object, the technical solution used in the present invention is: the locking-typed dual safe combined type blade plate of a kind of Wicresoft near end of thighbone restriction contact, comprise and the blade plate head of femoral bone tuberosity lateral surface coupling and the blade plate connecting rod that mates 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, be characterized in that described blade plate head is provided with three thread lock holes that are triangular row portion, be penetrated with the spherical pulling force nail that locks femoral bone tuberosity, neck of femur and bulb at least one the thread lock hole.
Described 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 described three thread lock holes.
Described 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 described blade plate connecting rod include more than one locking and pressurizing hole.
Follow closely a thread lock hole of cross-under blade plate head earlier with a ball shape pulling force, spherical pulling force nail is worn to the tuberosity bulb through neck of femur by the tuberosity outside, produce pulling force and can regulate the fracture clearance distance, 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.
The present invention 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.
