Abstract
The invention relates to a minimally invasive tuberositas comminuted fracture back side pressurizing type fixation bone fracture plate, which is formed by connecting a tuberositas back side fixing plate and a backbone fixing plate through a connecting plate, wherein the tuberositas back side fixing plate is in an arc-shaped curved surface structure anastomotic with the tuberositas back side surface, both ends of the tuberositas back side fixing plate are respectively provided with locking holes, locking nails penetrating through the tuberositas crown head end back side and the crown bottom end back side are respectively locked in the two locking holes, the backbone fixing plate is in a connecting plate structure anastomotic with the thighbone backbone back side surface, both ends of the backbone fixing plate are respectively provided with locking holes, and locking nails penetrating through the thighbone backbone are respectively locked in the two locking holes. When spherical nails are locked in a waist-shaped spherical groove, the direction and the angle can be adjustable, the tension of the femoral neck and the tuberositas and the tension of the broke bone of the tuberositas are respectively realized, the tuberositas comminuted fracture part is completely fixed, the spherical nails are penetrated and connected onto the backbone fixing plate in a matched way for tightly locking the thighbone backbone, the integral fixation effect is good, the accurate resetting is favorably realized, and the treatment effect is good.
Description
Technical field
The present invention relates to the orthopaedic medical treatment technical field, is a kind of Wicresoft tuberosity comminuted fracture rear side pressing type fixation bone fracture plate 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.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, easy to operate, otch is little, and locking is stable, helps proper reset, does not influence femoral bone cavitas medullaris and fracture regrowth, Wicresoft's tuberosity comminuted fracture rear side pressing type fixation bone fracture plate that therapeutic effect is good.
In order to achieve the above object; The technical scheme that the present invention adopts is: a kind of Wicresoft tuberosity comminuted fracture rear side pressing type fixation bone fracture plate; Its technical characterstic is that blade plate is formed by connecting through connecting plate tuberosity rear side fixing head and key fixing head; Tuberosity rear side fixing head is the arc line type curved-surface structure that coincide with the tuberosity trailing flank, and the two ends of tuberosity rear side fixing head are respectively equipped with lock hole, locks the locking nail that runs through tuberosity crown head end rear side and hat bottom rear side in two lock holes respectively; Key fixing head is the link configuration of coincideing with the key trailing flank of femur, and the two ends of key fixing head are respectively equipped with lock hole, locks respectively in two lock holes to run through the key locking nail of femur.
The centre of said tuberosity rear side fixing head is provided with lock hole, and the lock hole lock runs through the locking nail of tuberosity middle part rear side.
Said lock hole is ball-type waist type groove, and locking nail is spherical nail.
Said key fixing head be vertically or crosswise fixed on the femur backbone.
Lock hole position on said tuberosity rear side fixing head and the key fixing head interconnects through connecting plate.
The tuberosity rear side fixing head and the tuberosity trailing flank of blade plate of the present invention fit like a glove, and utilize in the waist type ball-type groove of spherical nail cross-under on tuberosity rear side fixing head, and direction and adjustable angle realize the tension of neck of femur and tuberosity and the tension of the broken bone of tuberosity respectively in the time of in the spherical nail locking waist type ball-type groove; Need only blade plate can be installed in the tuberosity posterior incisions, simple to operate, otch is little; Fixing comprehensively to tuberosity syntripsis place, cooperate the tight femur backbone of the spherical lock of cross-under on the key fixing head, overall fixed is effective; Strain firm, non-loosening, life-time service does not have potential safety hazard, helps resetting accurately; Indeformable, therapeutic effect is good.
Description of drawings
Fig. 1 is a mounting structure sketch map of the present invention.
Among the figure: neck of femur 1, tuberosity 2, tuberosity rear side fixing head 3, key fixing head 4, connecting plate 5,51, ball-type waist type groove 6,7, key 8.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Shown in Figure 1; A kind of Wicresoft tuberosity comminuted fracture rear side pressing type fixation bone fracture plate is formed by connecting through connecting plate 5,51 tuberosity rear side fixing head 3 and key fixing head 4; Tuberosity rear side fixing head 3 is the arc line type curved-surface structure that coincide with tuberosity 2 trailing flanks; The two ends of tuberosity rear side fixing head 3 and centre are respectively equipped with ball-type waist type groove 6, lock the sphere nail that runs through tuberosity crown head end rear side, hat bottom rear side and intermediate ends rear side in the ball-type waist type groove 6 respectively; Key fixing head 4 is the link configuration of coincideing with key 8 trailing flanks of femur; Key fixing head be vertically or crosswise fixed on the femur backbone; The two ends of key fixing head 4 are respectively equipped with and lock the sphere nail that runs through femur key 8 in ball-type waist type groove 7, the two ball-type waist type grooves 7 respectively; Tuberosity rear side fixing head 3 is provided with the position of ball-type waist type groove 6 and position that key fixing head 4 is provided with ball-type waist type groove 7 is corresponding each other interconnects through connecting plate 5,51.
