Abstract

The utility model discloses a limited contact locking compression plate, comprising a body portion (1) and a head portion (2). The head portion (2) and the body portion (1) axially takes on an angle of 20 degrees, the near-to-bone face of the body portion horizontally takes on an arc shape, sliding compression holes (5) are staggered on the body portion (1) along longitudinal direction, depressions (3) are alternatively arranged on the two longitudinal lateral sides of the body portion (1), a pull compression hole (4) is arranged on the head portion (2) with a shape of shake head, and a compound compression hole (6) is mounted on the body portion (1). The utility model has simple structure and convenient employment, which is not only beneficial for the reduction and fixation of fracture of proximal humerus and fractures around knee, but also avoids partial injury which is caused by infirm fixation, and bone nonunion which is caused by bone defect generated by stress shielding and broken end bone absorption.

Description

Limited contact locking compression steel plate
Technical field
This utility model belongs to technical field of medical instruments, relates to the fixed steel plate of a kind of human fracture of being used for, and more particularly relates to a kind of proximal humerus and the fixed limited locking compression steel plate that contacts of the knee joint peripheral reduction of the fracture.
Background technology
In the daily life, various unexpected injuries cause proximal humerus and knee joint peripheral fracture, traditional Therapeutic Method normally adopts the open reduction internal fixation treatment, because the bones of limbs metaphysis is a spongy bone, take place fixing insecure easily, the damage of local blood fortune produces stress shielding and broken ends of fractured bone bone resorption and often causes bone damaged and bone does not connect takes place.Not only union of fracture difficulty of traditional method and complication are more, and at present, domestic also do not have a kind of comparatively ideal internal fixation device to can be used for proximal humerus and knee joint peripheral treatment of fractures.The design people had once developed a kind of limited contact slip pressurization condyle plate (ZL99241416.4), overcome the deficiency of conventional fixed method well, but especially easily generation is fixing insecure with serious osteoporosis person for comminuted fracture, may influence union of fracture.For this reason, the designer has developed a kind of limited contact locking compression steel plate through concentrating on studies, evidence, and effect is good.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, the limited contact locking compression steel plate of reduction of the fracture good fixing effect.
The purpose of this utility model is achieved in that and comprises body and head, head and body axially are 20 ° of angles, it is laterally curved that body pastes surface of bone, the longitudinally staggered slip pressurization of body hole, and the vertical dual-side of the body depressed area that is crisscross arranged, " snakehead shape " head is provided with pulling force pressurization hole, also is provided with compound pressurization hole on its body.
Because this utility model special structural design, the biomechanics characteristic that meets proximal humerus, distal femur and proximal tibia especially, can reduce the damage of bone fixation section blood fortune and the generation of prevention of osteoporosis, and can prevent the generation of stress shielding, promote union of fracture.Easy to adjust, the accurate and effective of this utility model is inserted formality and is greatly simplified, and can make above-mentioned fracture obtain reduction with good, fixing, thereby have the excellent development application prospect.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model is described further, but is not limited to shown in the accompanying drawing.
Fig. 1 is this utility model front view;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the upward view of Fig. 1;
Fig. 4 is that the AA of Fig. 1 is to view.
Wherein: 1 is body, and 2 is head, and 3 is the depressed area, and 4 are pulling force pressurization hole, and 5 are the pressurization hole of sliding, and 6 is compound pressurization hole.
The specific embodiment
Shown in Fig. 1-4, this utility model comprises body 1 and head 2, head 2 axially is 20 ° of angles with body 1, it is laterally curved that body 1 pastes surface of bone, the longitudinally staggered slip pressurization of body 1 hole 5, and body 1 vertical dual-side depressed area 3 that is crisscross arranged, " snakehead shape " head 2 are provided with pulling force pressurization hole 4, also are provided with compound pressurization hole 6 on its body 1.
Described depressed area 3 is in wave shape, on the length of general every 10cm left and right sides 1-3 depressed area 3 is set.
Described pulling force pressurization hole 4 is a screwed hole, generally is isosceles triangle and arranges.
Described slip pressurization hole 5 is a screwed hole, is generally 2-3 the pressurization hole 5 of sliding is set on the length of every 5cm left and right sides.
Described compound pressurization hole 6 is the composite construction that is threaded the pressurization hole in fixing hole and 3/4 week, and 1 compound pressurization hole 6 is set on the length of every 5cm left and right sides.
As embodiment, according to clinical needs, this patent steel plate is provided with 5 holes, 7 holes, 9 holes, 11 holes, 13 holes totally 5 kinds of models temporarily at present.Wherein 5 holes, the far and near end of 7 hole steel plates respectively have 1 composite holes, and 9 holes, the far and near end of 11 hole steel plates respectively have 2 composite holes, and the far and near end of 13 hole steel plates respectively has 3 composite holes.
Operation principle of the present utility model and work process:
When reality is used, this utility model body pastes a plurality of asymmetric waveform depressed area 3 that the surface of bone both sides are provided with, steel plate and key contact area have been reduced, therefore can avoid the damage of bone fixation section blood fortune and the generation of prevention of osteoporosis, but parameters such as the intensity of steel plate and elastic modelling quantity are unaffected.The steel plate body is provided with a plurality of slips pressurization hole and compound pressurization hole, tighten by forcing screw for Fracture Simple and can make key outside tensile stress change vertical compressive stress into after fixing, fracture site is produced the axial pressure effect, can prevent the generation of stress shielding, promote union of fracture.According to state of an illness needs, utilize the special construction of composite holes can select locking fixing and add press fit.The head that turns up makes steel plate to fit with proximal humerus, distal femur and proximal tibia sclerotin better.3 pulling force pressurization holes of its head can adopt lag screw that the metaphysis spongy bone is carried out horizontal drawing, adds press fit.And, especially then adopt bridging technology and inner fixed support to reset fixing by lock screw with serious osteoporosis for comminuted fracture around the joint.
The utlity model has simple in structure, easy to use, it is fixing not only to help resetting of proximal humerus and knee joint peripheral fracture, and can avoid fixing insecure, the damage of local blood fortune, the generation of bone does not connect phenomenon due to the bone that stress shielding and broken ends of fractured bone bone resorption cause is damaged.
