Abstract
The utility model discloses a non - support multidimension radius distal end external fixation of fracture ware belongs to external fixation medical instrument technical field, is applicable to fixed the reseing of chi radius distal end fracture, the utility model discloses need not any chuck, do not have and support, simple structure, spheroid control spicule can 360 rotate, guarantee that the spicule has 0 -25's inclination, realize spicule multidimension nature inserting needle mode, and both ends press from both sides the faller realizes strutting the pressurization function through the spout, makes things convenient for the doctor to operate, and full structure adopts titanium alloy material, and intensity is high, and density is little, has not only increased product mechanical properties but also has alleviateed patient's health and born a burden, pursue under simple, swift, the pleasing to the eye theory at current medical instrument, the utility model discloses a selection of ideal.
Description
Technical field
This utility model relates to wrist fracture extenal fixation product, belongs to extenal fixation technical field of medical instruments, helps the rear fixed reset product of carpal joint damage.
Background technology
The kind of extenal fixation product gets more and more, but no matter be single-side multifunctional extenal fixation or combination type extenal fixation, the direction of inserting needle is all subject to the restriction of extenal fixation product itself, folder pin position forever and support body own perpendicular or parallel, the angled skew of spicule could be realized by switching clamp needle construction device, the designing requirement more complicated of this spline structure, operate also more loaded down with trivial details, on this basis, my company is according to the principle of implant blade plate, the needle plate designing a kind of extenal fixation coordinates external fixer, trouble when saving the device of folder needle construction and install, realize principle simple to operation.
Summary of the invention
Design comparison of the present utility model is reasonable, easy for installation, and structure is simple, is applicable to applying.
The technical solution of the utility model is as follows:
This utility model is non-supported multidimensional external fixer for radius distal fracture, needle (1) is pressed from both sides by far-end, near-end folder needle (2), interior hexagonal marks closely screw (3), spring spheroid (4) is formed jointly, it is characterized in that: near-end folder needle (2) and far-end are pressed from both sides needle (1) and cooperatively interacted by chute type block, realize the function strutting or pressurize, its junction is screwed, simple and convenient needs uses too many apparatus, an inner hexagon spanner can complete, the benefit that chute coordinates is, it is relative shaftless in rotary moving that far-end folder needle (1) and near-end press from both sides needle (2), ensure that the stability of spicule, unclamp screw can strut or pressurize.Far-end folder needle (1) and near-end press from both sides the folder pin ball of needle (2) from the horizontal by the angle of 25 degree, when putting into spring spheroid (4), ball and spring spheroid (4) contact with each other, spicule is made to press from both sides the movable angle producing 0-25 degree in needle (1) and near-end folder needle (2) at far-end, the angle number of degrees of alternating inclinations inserting needle when this angle meets Fracture of the distal ulna and radius, spring spheroid (4) external diameter is spherical simultaneously, internal diameter is screwed hole, its overall dimensions is greater than the size 1.3mm of far-end folder needle (1) and near-end folder needle (2) ball, itself open the groove of a 1.5mm, far-end folder needle (1) and near-end folder needle (2) ball is put into by extrusion spring spheroid (4) distortion during assembling, spring spheroid (4) opening flicks naturally afterwards, and spring spheroid (4) is fixed in far-end folder needle (1) and near-end folder needle (2) ball, never drop-off.The outside dimension of spicule is less than the size 0.5-0.8mm of spring spheroid (4) internal thread hole, during fixed bone spicule, mark closely the distortion of screw (3) extrusion spring spheroid (4) by hexagonal in precession and lock spicule, the deflection of locking spicule be less than spring spheroid (4) far-end folder needle (1) and near-end press from both sides in needle (2) ball minimum deviate from activity 1.3mm, simultaneously because endoporus is screw thread design, prevent spicule from rotating or moving up and down, self locking-type structure this, both the time in operation process had been decreased, also the complexity of operation is greatly reduced.Far-end folder needle (1), near-end folder needle (2), spring spheroid (4) all adopt titanium alloy material, intensity is higher than aluminium alloy, density is less than rustless steel, add integrally-built intensity, alleviate overall weight, be convenient for carrying, revolutionary improvement is brought to the life after operation in patients.
This utility model compared with prior art has the following advantages:
1 spheroid controls spicule, and motility, directivity improve;
2 soket head cap screws control spheroid, convenient and swift;
3 adopt titanium alloy material, and intensity is high, and density is little, corrosion resistance and good, have both alleviated patient body and have born a heavy burden, increased mechanical performance again.

Detailed description of the invention
Below in conjunction with an example, the utility model is described in further detail.
After the radioulnaris distalis of patient is fractured, need fracture replacement and fixation, select this utility model, first a spicule is squeezed at radioulnaris distalis, this utility model is inserted on spicule, second spicule is squeezed into through this utility model in adjacent position, screw interior hexagonal and mark closely screw (3), first two spicules of fixing upper far-end, third and fourth spicule is squeezed into again by this utility model product, use the same method after fixed bone spicule, the distance of ulna and radius near-end and far-end spicule is adjusted by the far-end chute pressed from both sides between needle (1) and near-end folder needle (2), screw after suitable interior hexagonal mark closely screw (3) stationary remote is pressed from both sides needle (1) and near-end folder needle (2), complete this operation.
Claims (4)
1. a non-supported multidimensional external fixer for radius distal fracture, press from both sides needle (1) by far-end, near-end presss from both sides needle (2), interior hexagonal marks closely screw (3), spring spheroid (4) is formed jointly, it is characterized in that: near-end folder needle (2) and far-end are pressed from both sides needle (1) and cooperatively interacted by chute type block, be screwed, relatively shaftless in rotary moving, unclamping screw can strut or pressurize.
2. the non-supported multidimensional external fixer for radius distal fracture according to claims 1, it is characterized in that: the folder pin ball of far-end folder needle (1) and near-end folder needle (2), from the horizontal by the angle of 25 degree, the movable angle of spring spheroid (4) generation 0-25 degree in far-end folder needle (1) and near-end folder needle (2), the angle number of degrees of alternating inclinations inserting needle when this angle meets chi, radius far-end fracture.
