Abstract
The utility model relates to the field of medical appliances, comprising a round bone needle, a pressurization bow frame, a rotary cap and a rotating seat. A movable shaft fixed on the rotary cap is connected with the rotating seat. The pressurization bow frame is fixed to the rotating seat by axial connection. The end head of the lower part of the pressurization bow frame is provided with a threaded rod and a screw nut. Regulating the needle screwing-in direction and the pressurized point to achieve the satisfactory treatment-effect of fixation, the utility model has the advantages of simple structure, convenient operation and reliable fixation and wearing convenience for the patient.
Description
This utility model belongs to medical instruments field, particularly relates to the fixer of the non-Surgery Treatment of bone lattice or joint.
Acromioclavicular joint dislocation is more common traumatic disease, the common at present seriality that adopts operative therapy and non-operative treatment realization acromioclavicular joint to reset and recover muscle, ligament.Operative therapy is used for non-operative treatment failure and old traumatic patient more.Non-operative treatment adopts suspender belt and pressure dressing, sticking cream fixing etc. more.In recent years, the treatment report that also has the external plaster fixation method.Above-mentioned non-operative treatment external fixation reliability is relatively poor, has influenced therapeutic effect." acromioclavicular joint reduction fixture device " utility application (application number 88219915.3) of Patent Office of the People's Republic of China's bulletin on April 26th, 89 has adopted the external fixer fixing means, though bigger improvement is arranged than said method, but because the fixed mount angle on the pressure point is difficult to conversion in the operation, the holder accessory is many, causes the big defective of operation limitation.In patient's use, because the holder height exceeds shoulder apart from bigger, patient wears the clothes and is affected, and has worn certain difficulty in addition.
It is reliable that the purpose of this utility model provides a kind of fixing point limitation, can guarantee adjacent joints activity within the specific limits, the acromioclavicular joint reseting fixture that the patient is easy to use.
For achieving the above object, this utility model has designed osseous pin, turncap and the rotating seat of the pressurization shelf of an energy different rotation angle and cooperation with it.The movable axis and the rotating seat that are cemented on the turncap join, and the pressurization shelf of two bow plate symmetries installation is connected with rotating seat by axle, on the termination, bottom of pressurization shelf screw rod and nut is arranged.When using this utility model, formerly be through at clavicle outer end and acromion respectively with three, and be connected on the turncap with osseous pin.By the movable axis on the turncap, adjust the angle of turncap, after selected suitable pressurization direction was fixing, pressurization shelf persistent pressure forced the embolia of dislocation, and by screw rod and nut, is fixed on the ideal position.Because the axle that the pressurization shelf links to each other with rotating seat can rotate, after pressurization was finished, the pressurization shelf can be adjusted rotation arbitrarily.
This utility model can be adjusted inserting needle direction and pressure point, to adapt to the adjustment of the different lopsided types of patient and the bodily form, reaches satisfied fixation for treatment effect.Have simple in structure, easy and simple to handle, fixing reliable, patient and wear characteristics easily.
Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings.
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, this utility model comprises and holds pin turncap (1), osseous pin (7), rotating seat (2), pressurization shelf (4).The movable axis (8) that is cemented on the turncap (1) joins with rotating seat (2), and its joint is the dentation engaging structure.The pressurization shelf (4) of two bow plate symmetries installation is connected with rotating seat (2) by axle (3).On the termination, bottom of pressurization shelf (4) screw rod (5) and nut (6) are arranged.When using this utility model, three osseous pins (7) are through at clavicle outer end (wearing) and acromion (wearing two) respectively, and are connected to and hold on the pin turncap (1).Adjust angle on the turncap to suitable pressing position, by the dentation engages fixed on rotating seat (2).Pressurization shelf (4) persistent pressure, the embolia of traction dislocation.Screw the nut (6) on the screw rod (5), the shelf (4) that will pressurize is fixing to get final product.
Claims (2)
1, a kind of acromioclavicular joint external fixer that resets, it is characterized in that it comprises holds pin turncap (1), osseous pin (7), rotating seat (2), pressurization shelf (4), the movable axis (8) that is cemented on the turncap (1) joins with rotating seat (2), the pressurization shelf (4) of two bow plate symmetries installation is connected with rotating seat (2) by axle (3), on the termination, bottom of pressurization shelf (4) screw rod (5) and nut (6) is arranged.
