Abstract
The utility model discloses a double motive force screw humerus steel plate that is used in internal fixing of fracture of proximae humerus and 1/3 humerus. The utility model pertains to the technical field of medical appliances. On the basis of exiting motive screw, the utility mode replaces single sleeve steel plate into double sleeve steel plate 1 and single motive screw into double motive screw 3. The utility model overcomes the shortages of instable fixing and poor rotary in proximae humerus fracture restoring. The utility model is convenient and reliable to be used.
Description
(1) technical field: this utility model relates to a kind of humerus steel plate, is used for the internal fixation of 1/3 fracture on fracture of the surgical neek of the humerus and the humerus.Belong to technical field of medical instruments.
(2) background technology: 1/3 fracture on fracture of the surgical neek of the humerus or the humerus, previously have only T-shape steel plate, common synthetism steel plate, Kirschner wire or sponge screw etc. to make internal fixation.They all exist fixing not firm, fixing shortcoming such as difficulty.And Hip Fracture, useful dynamic hip screw steel plate (dynamic hip screw) is made internal fixation.This dynamic hip screw steel plate is by single sleeve steel plate and place the power screw two parts in the sleeve to form.Because it only fixes with single action power screw, anti-rotatory is poor, and only is applicable to Hip Fracture, and can not be applicable to 1/3 fracture on fracture of the surgical neek of the humerus or the humerus.
(3) summary of the invention: the purpose of this utility model is to provide a kind of power screw humerus steel plate that can be used for 1/3 fracture internal fixation on fracture of the surgical neek of the humerus and the humerus.This utility model technology contents is: a kind of double dynamical screw humerus steel plate is on the basis of motive power hip screw steel plate, and changing single sleeve steel plate is double dynamical screw for two sleeve steel plates, single action power screw.Because this utility model adopted double dynamical bolt structure, the fracture of the surgical neek of the humerus shortcomings such as fixing not firm, anti-rotatory difference that reset have been overcome.Clinical practice is convenient, and operation technique is simple, and is fixed.
(4) description of drawings:
Fig. 1 is a Facad structure sketch map of the present utility model.
Fig. 2 is a side structure sketch map of the present utility model.
Fig. 3 is a vertical view of the present utility model.
(5) specific embodiment:
Below in conjunction with accompanying drawing this utility model is described in further detail:
As Fig. 1-3, this utility model is a kind of double dynamical screw humerus steel plate.Form by two sleeve steel plates 1 and double dynamical screw 3 two parts.Double dynamical screw 3 is arranged in the sleeve 2 on two sleeve steel plate 1 tops.Angle α between two sleeve steel plates 1 and the double dynamical screw 3 is 100-130 °.Centre-to-centre spacing between 1 liang of sleeve 2 afterbody of two sleeve steel plates is 18-22mm.Angle β between two sleeves 2 is 10-15 °.Between steel plate part two fixed screw holes 4 of two sleeve steel plates 1 certain matrix waveform 5 is arranged, little to the diaphyseal bone membrane damage, help union of fracture
During operation, two pieces of power screws 3 are pressed certain angle screw in the head of humerus, settle two sleeve steel plates 1 then, again steel plate is fixed in humerus and does, tighten up power screw afterbody compression screw generation power fracture end is done to add press fit, make fracture end fixed.
Claims (5)
1, a kind of double dynamical screw humerus steel plate is characterized in that it comprises two sleeve steel plates (1) and double dynamical screw (3), and double dynamical screw (3) places in the sleeve (2) on two sleeve steel plate (1) tops.
2, a kind of double dynamical screw humerus steel plate according to claim 1 is characterized in that the angle α between two sleeve steel plates (1) and the power screw (3) is 100-130 °.
3, a kind of double dynamical screw humerus steel plate according to claim 1 is characterized in that centre-to-centre spacing e is 18-22mm between two sleeve steel plate two sleeves (2) afterbodys.
