Description
Technical field
The utility model belongs to manufacture technology field of medical appliance, and in particular to one kind is for femoral fracture in bone surgery
And the memorial alloy femur fracture plate that hip replacement prosthese secondary fracture is overhauled.
Background technique
As China enters aging of population, the fracture of neck of femur of the tuberosity part of fractured near end of thighbone such as femur, femur are big
It fractures under intertrochanteric fracture and greater trochanter of femur, is common serious damage.Especially because the dissection particularity of neck of femur,
Once fracturing, very difficult, Chang Fasheng nonunion and avascular necrosis of femoral head, Gu Rengong are resetted and fixed
The quantity of hip replacement also increases therewith.Since the elderly is there are different degrees of osteoporosis, joint replacement is postoperative to crouch
Bed can aggravate osteoporosis again, therefore postoperative microtrauma often results in the generation of Periprosthetic fracture.The presence of prosthese makes treatment more
To be intractable, elderly patient that is poor especially for constitution, having severe osteoporosis or bone loss, if malpractice can be to disease
People brings unnecessary pain, even catastrophic consequence.
Traditional therapy has general steel plate, steel wire bundle, Mennen plate, improvement Mennen plate, the fixed system of steel plate wirerope
The fixation for treatment such as system, novel method for the treatment of have shape-memory alloy embracing fixator, less invasive stabilization systems, Lucking compression plate, different
The fixation for treatment such as body cortex bone plate, carbon fiber board, impaction bone grafting and revision procedure.The more treatment method of application is locking at present
Compression steel plate wirerope internal fixation treatment, allosome cortex bone plate joint wirerope is fixed and shape-memory alloy embracing fixator etc..
201510522320.8 Chinese patent of application number, title: " a kind of near end of thighbone position and lock steel plate fixing structure "
With 201610496636.9 Chinese patent of application number, the title: " Lucking compression plates such as Universal lock fixed board outside near end of thighbone joint
Joint wirerope " all have the disadvantage in that
1, after screw is installed in the threaded hole of fixation steel plate, over time, screw often occurs to loosen existing
As, and then influence fixed effect.
2, locking steel plate is in the presence of structure is complicated, bending strength is weak, not secured etc. enough technical problems of installation.
200920032685.2 Chinese patent of application number, title: " a kind of shape-memory alloy circumferential bone plate " and Shen
Please number 97250035.9 Chinese patents, title: " shape-memory alloy embracing fixators such as encircling bone bonding plate " have the disadvantage in that
1, suitable bone fracture device there is no for fracture of neck of femur and hip replacement secondary fracture.
2, current shape-memory alloy embracing fixator is single-spar construction, and it is smaller to encircle power after implantation, causes to be not fixed firmly and lean on
Or prosthese is unstable, is the postoperative major complications that secondary fracture occurs.
Utility model content
In order to solve the above-mentioned problems in the prior art, the utility model, which provides a kind of structurally reasonable, safety, to be had

Specific embodiment
Below with reference to specific attached drawing, the utility model is further explained and is illustrated；
As shown in Figure 1, 2, a kind of memorial alloy femur fracture plate, bone plate are twin beams bone plate, and twin beams bone plate is song
Panel；It is evenly distributed in the plate face of the length direction of curved slab to have rectangular opening 2, as shown in Fig. 2, the two sides of twin beams bone plate point
Be furnished in pair encircle arm, each pair of arm of encircling forms open annular structure, and each end for encircling arm is end tooth 10, is connect along twin beams
One end of bone plate length extends to form curved pressurization hook.As shown in figure 8, the end of pressurization hook is a pair of symmetrical hook 5, two
Hook forms U-shaped opening, and the end of two hooks is wedge angle, and the two sides of each hook melon 5 are equipped with taking-up branch 7 outstanding.Such as Fig. 2 institute
Show, is evenly arranged countersunk head sphere hole 7 along the length direction of pressurization hook main body plate face.And the diameter in hole has different size, to match
Close the Calcium phosphate cement for using different-diameter；Countersunk head sphere hole and screw head are adapted, and reduce entirety after cooperation implantation
Thickness and increase stability in use.As shown in fig. 6, the two sides of pressurization hook main body, are respectively provided with one with the symmetrical position of counter sink
The circular arc or straight line in recessed portion, limit when to be used cooperatively with metal cable, and the section of recessed portion.It is shown in FIG. 1 double
Beam bone plate is the straight configuration of equivalent width or the pyramidal structure that width changes from small to big, to adapt to different human body femur physiology solution
Feature is cutd open, and the stub end of any end of straight twin beams bone plate or taper twin beams bone plate is equipped with a pair of openings cyclic structure
It is larger to encircle arm, to be preferably bonded between greater trochanter and lesser trochanter, increase interior fixed effect.As shown in figure 3, open annular knot
The big split ring for encircling arm formation of structure is strip hole, as shown in figure 4, remaining encircles the open annular structure of arm formation as circle
Shape.Curve is dissected preferably to adapt to the physiology of femur.The logarithm for encircling arm is 2-8 pairs, and the arm width for respectively encircling arm is equal.Such as
Shown in Fig. 7, there are two groups of symmetric arrays to take out branch in each encircle on arm, and be symmetrically arranged in each pair of encircle on arm, with convenient
Taking-up after bone plate implantation, and the shape for taking out branch is rectangle or semicircle.
