Background technology
In fractures process, the treatment of fracture of femoral neck is a difficult point.It not easily heals, and screw fixedly requires high, and particularly old people is due to osteoporosis, if position of threading a needle is not good, holds in the mouth or the eyes nail loosely, and the fixing difficulty of screw, easy solid failure causes nonunion.Often need secondary joint replacement, add sensual misery and burden economically to patient.Therefore, in fact, for numerous patients with fracture of necks, all require two draw points to squeeze into the moderate position of femoral head neck, be just unlikely to lose efficacy, this has higher requirement to accuracy.In order to fixing accurately firm, usually adopt repeatedly X-ray examination technology at present, to determine orientation.This easily produces physical impairment to patient and doctor.
Summary of the invention
The object of the present invention is to provide a kind of fracture of femoral neck stationary positioned device, it can overcome the defect of prior art, thus is conveniently squeezed into by draw point exactly and be fixed in femoral head neck.
The object of the invention is to be realized by following scheme:
Fracture of femoral neck stationary positioned device, comprises a locating rod, and two draw points and actuator, is characterized in that: actuator is provided with collodiaphyseal angle location translation block and top rake locating rotation block.Specifically namely: actuator is made up of fixed block, slip moving block, slip moving block can slide relative to fixed block or/and rotate fixing, slip moving block be arranged two holes of threading a needle penetrated for draw point.
Slip moving block is formed: one end and the fixed block of moving block are flexibly connected and can rotate relative to fixed block, and the interior setting of moving block can fixed block planar sliding shoe relatively, sliding shoe is arranged two holes of threading a needle penetrated for draw point.
Slip moving block is formed: sliding shoe and fixed block are flexibly connected and planar can move relative to fixed block, arrange spill spin block, spill spin block is arranged two holes of threading a needle penetrated for draw point in sliding shoe.
The present invention also can realize further by following scheme:
The formation of actuator is: for the fixed block of up and down stationary positioned bar, locating rod is fixed on the tuberosity part of femur, arranges the pole perforating hole of locating rod in fixed block, and locating rod can slide up and down fixing in pole perforating hole, and it is fixed and screws realization by fixed knob; Fixed block side adopts shaft/bore corresponded manner, is connected with and can rotates fixing fixing head before and after fixed block, and it is fixed and screws realization by fixed knob; Fixing head, by frid structure, is connected with sliding panel, and sliding panel can slide fixing in fixing head, and it is fixed and screws realization by fixed knob; The other end of sliding panel is fixed on plate of threading a needle, and plate of threading a needle is arranged two holes of threading a needle, can place draw point in hole of threading a needle; Draw point finally squeezes into femoral head.
Described fixing head, sliding panel adopt corresponding arc to arrange, the center of circle of arc and femoral head place.
Intersect before and after two described draw points are formed and be fixed in femoral head.
It is 5-15 degree that two described draw points form staggered acute angle angle.
The present invention has following beneficial effect: adopt the present invention can realize fast and exactly being squeezed into by draw point and being fixed on femur.Its maximum feature is: 1, simple to operation; 2, reduce employing radioscopy, accurately realize the fixing of optimum position.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention; Fig. 2 is sliding panel of the present invention and fixing head schematic diagram.
In figure: 1 is femur, 2 is draw point, and 3 is plate of threading a needle, and 4 is sliding panel, and 5 is fixed knob, and 6 is fixing head, and 7 is fixed block, and 8 is fixed knob, and 9 is fixed knob, and 10 is locating rod.
Detailed description of the invention
In order to make those skilled in the art person understand the present invention program better, and enable above-mentioned purpose of the present invention, feature and advantage become apparent more, below in conjunction with drawings and Examples, the present invention is further detailed explanation.
Embodiment:
As shown in Figure 1 and Figure 2, fracture of femoral neck stationary positioned device, comprise a locating rod 10, two draw points 2 and actuator, the formation of actuator is: for the fixed block 7 of up and down stationary positioned bar 10, locating rod 10 is fixed on the tuberosity part of femur 1, arranges the pole perforating hole of locating rod 10 in fixed block 7, locating rod 10 can slide up and down fixing in pole perforating hole, and it is fixed and screws realization by fixed knob 8; Fixed block 7 side adopts shaft/bore corresponded manner, is connected with and can rotates fixing fixing head 6 before and after fixed block, and it is fixed and screws realization by fixed knob 9; Fixing head 6 is connected (see Fig. 2) with sliding panel 4 by frid structure, and sliding panel 4 can slide fixing in fixing head 6, and it is fixed and screws realization by fixed knob 5; The other end of sliding panel 4 is fixed on plate 3 of threading a needle, and plate 3 of threading a needle is arranged two holes of threading a needle, can place draw point 2 in hole of threading a needle.Femur 1 head finally squeezed into by draw point 2.
Fixing head 6, sliding panel 4 adopt corresponding arc to arrange, the center of circle of arc and femoral head place.
During use, locating rod 10 is fixed on the tuberosity part of femur 1, is observed by X-ray examination, unclamp fixed knob 5, the position of adjustment sliding panel 4, find correct collodiaphyseal angle, be tightened knob 5, like this, achieve tentatively determine draw point 2 squeeze into direction; Afterwards, unclamp fixed knob 9, rotate fixing head 6, thus find correct top rake, be tightened knob 9, finally squeezes into draw point 2, thus make two draw points 2 form staggered being fixed in femoral head.Afterwards, remove positioner, retain steel nail 2, be screwed into compression hollow screw along steel nail 2 and fix, exit steel nail 2, fixing complete.
