Abstract
The utility model relates to a bone fracture plate for a sternoclavicular joint. The bone fracture plate for the sternoclavicular joint is characterized in that 3-6 pairs of surrounded arms are arranged on a surrounded bone fracture plate body, and fixing pieces are arranged on at least one pair of the surrounded arm. In the using process, when fixation is offered by the bone fracture plate for the sternoclavicular joint, a clamping breastbone handle in a proximal side is fixed with a punching on breastbones, and contacted with the breastbones in a small face shape. Tiny motion exists between the clamping breastbone handle in the proximal side and the breastbone, and the tiny motion of the sternoclavicular joint is formed; bigger surrounded arms fix the proximal end of collarbones, so that the sternoclavicular joint keeps tiny motion after returning. The bone fracture plate for the sternoclavicular joint has no obvious interference to the tissues of the breastbones, the effect to the sternoclavicular joint is little, so that the bone fracture plate for the sternoclavicular joint has the advantages of being favorable for patients to functionally exercise in an early period, and capable of avoiding cracking of an inner fixing stuff. At the same time three-dimensional fixation can be achieved. For consistently holding force, the bone fracture plate for the sternoclavicular joint is not easy to loose and dislocate, and therefore restoration, fixation and function recovery after a surgery of the patients are favorable.
Description
Technical field
This utility model relates to the technical field of medical internal fixation device, and is specifically a kind of for special-shaped memory alloy plate osteosynthesis fixing in the dislocation of sternoclavicular joint.
Background technology
At present, dislocation of sternoclavicular joint in the world operation method is a lot, but curative effect is all dissatisfied, because there is fine motion in the joint, is prone to fragmentation of internal fixation objects through fixedly tension band, the steel plate etc. of sternoclavicular joint, operative failure, and patient is very painful.Wherein, breast latch hook steel plate be use now more a kind of, though described breast latch hook steel plate can reach the purpose of fine motion, but inside-fixture to breastbone after vital tissue disturb large, be not easy three-dimensional fixing, the easy generation become flexible and dislocation, is unfavorable for resetting, fixing and the postoperative function rehabilitation of patient joint, can cause obvious adverse consequences.
Summary of the invention
The purpose of this utility model is to provide a kind of improved blade plate for sternoclavicular joint, and it can overcome in the prior art disturbs greatly vital tissue behind the breastbone, easily causes the some shortcomings of obvious adverse consequences.
To achieve these goals, the technical solution of the utility model is: a kind of blade plate for sternoclavicular joint, it mainly comprises the encircling bone bonding plate body, it is characterized in that: the encircling bone bonding plate body is provided with 3-6 to encircling arm, encircles arm at least 1 pair and is provided with fixture.
Of the present utility model giving when being fixed during use, portions of proximal clamping presternum and with breastbone on punching fixing, be that the facet shape contact with breastbone, and between breastbone fine motion arranged, the fine motion of formation sternoclavicular joint; Encircle fixedly clavicle near-end of arm, closely be connected with the clavicle near-end, be difficult for looseningly, make the sternoclavicular joint rear maintenance fine motion that resets.The memorial alloy arm is close to the breastbone insertion behind the portions of proximal breastbone, tissue behind the breastbone is disturbed without obvious, impact on the sternoclavicular joint activity is little, be beneficial to patient's early functional exercise, avoided the fracture of inside-fixture, can reach three-dimensional fixing simultaneously, for continuing hold, be difficult for loosening and dislocation, be beneficial to resetting, fixing and the postoperative function rehabilitation of patient joint.
Description of drawings
Fig. 1 is the structural representation of this utility model one embodiment.
Fig. 2 is the another structural representation of this utility model one embodiment.
The specific embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
In the accompanying drawing, each labelling is expressed as follows: 1 encircling bone bonding plate body, 2 is encircled arm, 3 fixtures, 4 connecting plates, 5 U-shaped jig arm, 6 gib heads.
This utility model mainly comprises the encircling bone bonding plate body, and its difference with the prior art is: the encircling bone bonding plate body is provided with 3-6 to encircling arm, encircles arm at least 1 pair and is provided with fixture, and described fixture can prevent from encircling the arm rotation.Described encircling bone bonding plate body is formed by connecting by U-shaped jig arm and connecting plate, the middle part of connecting plate to end is provided with 3-6 successively to encircling arm, described 3-6 is dwindled to end diameter by the connecting plate middle part successively to encircling arm, and 3-6 is combined to form horn-like structure to encircling arm and connecting plate.Encircle arm and be provided with opening, the extended distance scope of opening is 4mm-6.5mm, and the opening angle of opening is 20 degree, and fixture is arranged on the side of opening, and described fixture is 2-5 fixed teeth or fixation hook, and fixed teeth adopts pointed tooth.The inboard of U-shaped jig arm is provided with a gib head, and gib head can pass from the boring of shirtfront and hook plastron, reaches sternoclavicular joint and resets fixing.
In force, the encircling bone bonding plate body is provided with 3 pairs and encircles arm, and this instrument proximal clamping presternum also punches from front to back on breastbone and fixes, and is that the facet shape contacts with breastbone, and between breastbone fine motion is arranged; A thick 1.6mm only behind the breastbone, length and width are the memorial alloy arm of 20mm*4mm, to vital tissue behind the breastbone substantially without obviously disturbing; The clavicle near-end is the pestle shape, and it is larger that diameter differs, and through measuring, the nearly articular surface 1cm of clavicle near-end place's diameter and clavicle middle part diameter differ and be about 0.3 cm, and the nearly articular surface 2.5cm of clavicle near-end place's diameter and clavicle middle part diameter differ and be about 0.15 cm.Therefore, the special-shaped memory alloy plate osteosynthesis of this novel sternoclavicular joint is encircled arm two of nearly articular surface one end of clavicle and is increased respectively diameter 0.3 cm, 0.15 cm, matches with the profile with the clavicle near-end, is beneficial to dislocation of sternoclavicular joint and resets fixing.The beneficial effects of the utility model: in the dislocation of sternoclavicular joint case, the breastbone shank standing part of design and clavicle section major diameter are encircled arm and can be resetted dislocation of sternoclavicular joint, fix, reach that sternoclavicular joint is fixed, the purpose of fine motion, and to tissue behind the breastbone without obviously disturbing.
