Abstract

The utility model relates to a fracture reposition fixer for long bones, belonging to medical instruments. The utility model provides an instrument causing the operation reposition and fixation of long bone fracture to be simple, effective, timesaving and laborsaving. The fixer is characterized in that a leading and longitudinal adjusting rod causes two bone-holders to be integration, and keep in parallel; movable claws with slots are arranged on the bone-holders, and can be adaptable to the requirements of different internal fixation instruments. One of the bone-holders can slide horizontally, favorable for reposition. The utility model can cause the long bone fracture with misplacement and overlapping firstly to be separated, and repositioned; after the internal fixation instrument is positioned in the movable slot, the longitudinal adjusting rod causes the internal fixation instrument to be pressurized and fixed on the fracture end, favorable for the healing of fracture.

Description

Fracture reposition fixator for long bone

This utility model belongs to medical apparatus and instruments.

For solving resetting and fixation problem of long tubular bone fracture, as far as we know, bone bone holding forceps and bone anchor are only arranged at present in the long tubular bone fracture operation both at home and abroad for assistance application.In the operative reduction process, especially during fracture of shaft of femur, for overcoming the strength between muscle, often want operator and other people simultaneously tractive can finish.The shortcoming of the method is a lot: the one, and waste of manpower, time, tractive itself is again a kind of pessimal stimulation to patient; The 2nd, reset before the boring of back, internal fixation apparatus is easy to slide up and down between inner fixer and tubular bone, makes the internal fixation position undesirable; The 3rd, the fixing back fracture end that resets is often because of pressurization leaves the space inadequately, thus the healing of influence fracture.

The purpose of this utility model be make the long tubular bone fracture operative reduction and fixing simple, effectively, save time, laborsaving, increase the contact surface of fracture end and the healing that promotes to fracture.

The purpose of this utility model is finished as follows: this apparatus is made by stainless steel material.Vertical accent bar of tape guide becomes one two bone holders; Each bone holder has movable claw, and one of bone holder can laterally slide.Vertically the accent bar can make fracture end overcome strength between muscle and separate, and is convenient to reset; Can before boring, make the fracture end pressurization again, be beneficial to the healing of fracture; Its separation and pressurization only need can realize by threaded vertical accent bar.The axis of guide can make two bone holders parallel mobile.Horizontal accent bar is arranged on the bone holder, both can make bone holder firmly hold bone, can make the fracture end lateral displacement by the effect of the bone holder that can laterally slide again, to reach the purpose of proper reset by transferring the bar effect.Movable claw divides three types: ordinary steel template, sliding steel plate type; The compression steel plate type, square on the upper side groove that has designed three kinds of different sizes is convenient to lay different internal fixation apparatus in it; Can make simultaneously internal fixation apparatus laterally transfer the more firm surface of bone that is affixed under the bar effect, and be unlikely mobile.The pre-operative surgical person can select suitable movable claw for use according to the difference of used internal fixation apparatus in the art.The fixing of movable claw realized by the movable claw holding screw.

Concrete structure is provided by following embodiment and accompanying drawing.

Fig. 1 is an A-A cutaway view of the present utility model.

Fig. 2 is a front elevation of the present utility model.

Among the figure 1, movable claw base component 2, movable claw holding screw 3, movable claw 4, fixed claw 5, guide pad 6, the axis of guide 7, vertically transfer bar 8, groove to transferring bar 9, axis of guide bearing support 10, axis of guide screw

In Fig. 1, it is fixing that movable claw base component (1) and movable claw (3) are marked closely screw (2) binding by movable claw, and movable claw (3) is held bone jointly with fixed claw (4), and its clamping bone is directly regulated by horizontal accent bar (8).(5) be guide pad.(6) be the axis of guide, no screw thread on it.

In embodiment illustrated in fig. 2, vertically transfer bar (7) and axis of guide bearing support (9) axis of guide screw (10) to link.Vertically transfer bar threaded, distance between its scalable two bone holders.

Claims

1, a kind of long tubular bone fracture reduction fixture device becomes one two bone holders by vertical accent bar, and it is characterized in that: vertically transfer bar that the axis of guide is arranged, bone holder has the movable claw of fixed claw and belt grooves.

2, long tubular bone fracture reduction fixture device according to claim 1 is characterized in that: vertically transfer the axis of guide of bar not have screw thread; The movable claw of bone holder divides the ordinary steel template, sliding steel plate type, three kinds on compression steel plate type.
