Abstract
The utility model relates to an assistant equipment of stainless steel applied in the medical orthopedic operation, which consists of a T-shaped screw, a threaded rod and four nuts, a semi-ring arc device, a locker, and two skeletal tractions. Two fixation screws and the T-shaped screw are respectively positioned in the distance of two broken ends of the fracture. The threaded rod connects with the semi-ring arc device. The nut is screwed besides the T-shaped screw on the threaded rod to distract the broken ends of the displacement fracture, and based on the above operation, the characteristics of the arc device is smartly used through adjusting the two screws on the arc device-ingeniously: the device could vertically and horizontally move and meanwhile rotate along the arc, thus to easily correct the rotation displacement of the angulations between two fracture broken ends. After the reduction of two fractures broken ends, the nut on the threaded rod is screwed again to make stable with pressure between fractures broken ends.
Description
Affiliated technical field
This utility model relates to a kind of rustless steel operating theater instruments of using in the bone surgery in medical treatment.
Background technology
The dilator of using in the simple fracture operation is arranged in present bone surgery, the spherical multidirectional external fixator of the single armed of fracturing in addition, complicated, dumb when these apparatuses are used; All strut and pressurize, but all less than well correcting rotation and dislocation function.The operating room that has also is equipped with the bone surgery bed, can draw the auxiliary reduction of the fracture in operation, but because of it is the traction of over-articular, so can not play the effect of pressurization.What application was maximum in the bone surgery of reality still is by traditional method, carries out the tractive manual reduction by patient and assistant.All these methods all can not reach the effect of further pressurizeing again behind very satisfied, the stable anatomical reduction.
Summary of the invention
In order in the long bone shaft fracture operation, to correct dislocation and the rotation between the fracture site better, this utility model provides a kind of simple and practical can making to reach anatomical reduction between the fracture site, can fixedly provide best pressurization steady-state conditions for next step plate screw again.
The technical scheme that its technical problem that solves this utility model adopts is: at first select a bit to be screwed into the T-shape screw by electric drill boring in the nearly section of fracture, be screwed into two long spiro nails or thicker steinman pin in fracture section far away equally; Then the T-shape screw is fixed on the long threaded rod; Feature of the present utility model is that the screw with two far-ends is fixed on the semi-ring arc apparatus and locks, the steel plate of following threaded rod to connect is vertical with the semi-ring curved plate and is connected, turn the nut on the T-shape screw limit on the threaded rod, make between the fracture site that misplaces into the angle and strutted, adjust two screws on the arc apparatus on this basis---utilize the characteristics of arc apparatus dexterously: can about, move left and right fracture section far away, can also be rotated along arc simultaneously, correct very like a cork and be rotated into angular misalignment between the fracture site.Treat between the fracture site behind the anatomical reduction, oppositely twist nut on the threaded rod again and make between the fracture site pressurization stable; For carrying out plate screw, next step fixedly provides optimum condition.
The beneficial effects of the utility model are, make on the basis that fracture site strutted turning nut on the threaded rod, situation according to fracture site dislocation rotation, utilize the characteristics of arc apparatus, adjust the screw on the semi-ring arc apparatus, be rotated into angular misalignment between the fracture site thereby correct very like a cork.

The specific embodiment
1. femoral shaft models in Fig. 1,2. the T-shape screw inserts the femoral shaft near-end, 3. locking nut, turning nut moves the T-shape screw on threaded rod, 4. threaded rod connects T-shape screw and semi-ring arc apparatus, 5. semi-ring arc apparatus, in semi-ring arc apparatus groove, fix the locking pin that inserts the fracture far-end, 6. pinning device by the pinning device.
5. semi-ring arc apparatuses in Fig. 2,6. pinning device 7. fixing locking pins that insert the fracture far-end in semi-ring arc apparatus groove.
Fig. 3 Fig. 4 be the fixing locking pin that inserts the fracture far-end of pinning device section and above sketch map.
Claims (2)
1, the three-dimensional and rotation of fracture struts the pressurization apparatus, and it comprises a T-shape screw, a threaded rod and 4 nuts, semi-ring arc apparatus and pinning device, two medullo-puncture needles; It is characterized in that: two hold-down screws and T-shape screw are individually fixed in the distant place of two broken ends of fractured bone of fracture, and connecting thread bar and semi-ring arc apparatus are fixed on the screw of two far-ends in the arc apparatus groove and lock.
2, fracture three-dimensional according to claim 1 and rotation strut the pressurization apparatus, it is characterized in that: semi-ring arc apparatus is the medical stainless steel steel plate, the diameter range of arc is 2-30cm, and the arc angular range is the 10-270 degree, and steel plate width is that 0.8-8cm, thickness are 0.1-0.5cm; Fluting in the middle of the steel plate, the width of groove and curved plate width are complementary.
