Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is A part of the embodiment of the present invention, instead of all the embodiments.The present invention being usually described and illustrated herein in the accompanying drawings is implemented The component of example can be arranged and be designed with a variety of different configurations.
The present embodiment demonstration discloses a kind of posterior lumbar spinal surgery device for spreading;Device through this embodiment can be in waist Cone section is stablized in vertebra way of escape Invasive lumbar fusion device fusion and is accurately strutted.
In order to realize above content, Fig. 1 and Fig. 2 is please referred to;The device of the present embodiment includes rail assembly 100, mutually puts down Capable first struts arm 200 and second struts arm 300.First struts arm 200 and second struts arm 300 respectively in rail assembly 100 length direction sliding realizes that cone section is softened in the length direction of rail assembly 100.
Referring to FIG. 3, the rail assembly 100 of the present embodiment include backboard 110, the integrally formed upper plate 120 of backboard 110 and under Plate 130.It is fixed with upper sliding rail 121 in upper plate 120, lower plate 130 is fixed with glidepath 131.Backboard 110 upper sliding rail 121 and under Part between sliding rail 131 is fixed with rack gear 140 along its length.
Please refer to Fig. 4 and Fig. 6, the first of the present embodiment strut arm 200 and second strut arm 300 structure it is identical, thus The structure for only strutting arm 200 to first in embodiment is illustrated.First struts arm 200 including traversing piece 210, traversing piece 210 are connected with operation panel 220 by Bolt dismantling, and operation panel 220 offers perforative 242 hole of shaft, and 242 hole of shaft passes through axis It holds and is connected with shaft 242, one end of shaft 242 is coaxial fixed with gear 241 after passing through traversing piece 210, the other end and manual pulley 243 is coaxial fixed, and gear 241 is engaged with rack gear 140.
In some embodiments, first strut arm 200 and second strut arm 300 blade be bent outwardly in outer offset eight Word structure.
Fig. 5 and Fig. 6 is please referred to, traversing piece 210 side in opposite rack gear 140 of the present embodiment has been bolted two A top shoe 250 and two sliding blocks 260.Two top shoes 250 cooperate with upper sliding rail 121 respectively, and two sliding blocks 260 are distinguished Cooperate with glidepath 131.
Through the above scheme, after being struck, with respect to rack gear 140 position occurs the manual pulley 243 in embodiment for gear 241 Move, traversing piece 210 upper sliding rail 121, glidepath 131 and top shoe 250, sliding block 260 cooperation under only can be along rack gear 140 Length direction displacement.It can be relatively distant from traversing piece 210 fixed opposite second strut of the first strut 400 or close.By There is certain self-locking feature in the engagement of gear 241 and rack gear 140, enable the first strut 400 and the second strut certain Continue and stable strut cone section provides operative space for medical staff.Meanwhile the cooperation of gear 241 and rack gear 140 can It is accurately controlled the first displacement stroke for strutting 200 relative orbit component 100 of arm, realizes the accurate control to the amplitude that struts.
Referring to FIG. 4, another side that operation panel 220 opposite second struts arm 300 is configured with and passes through spiral shell with traversing piece 210 Tether the cushion block 230 connect.Side plate 150 at 110 both ends of backboard is respectively fixed with elastic bumps 160, and elastic bumps 160 are towards pad Block 230.So medical staff stir manual pulley 243 make first strut arm 200 along rack gear 140 displacement reach maximum distance When, elastic bumps 160 can withstand cushion block 230, place the first strut 400 and the second strut and excessively strut to cone section, cause to disease The injury of trouble.
Referring to FIG. 7, traversing piece 210 of the present embodiment is fixed the first strut 400, the first strut 400 by Bolt dismantling Length direction it is vertical with the length direction of rack gear 140.First strut 400 is offered along its length for laying lighting fiber Cabling channel 410, offer the lightening hole being connected to cabling channel 410 in traversing piece 210 relatively of the other end of the first strut 400 420, lightening hole 420 runs through the two sides of the first strut 400.
Through the above scheme, the first of the present embodiment struts through the external lighting fiber of cabling channel 410, the end of lighting fiber End is protruded into lightening hole 420 through cabling channel 410, provides lighting source to the first distracted two sides.
Referring to FIG. 7, the present embodiment is configured with transparency cover 430 in the two sides of the first strut 400, transparency cover 430 is for close The covering cabling channel 410 and lightening hole 420 of envelope, anti-Hemostatic Oral Liquid or tissue enter in cabling channel 410 or lightening hole 420, give Medical staff causes unnecessary cleaning to bear.
The one side of opposite second strut of first strut 400 of the present embodiment is that inside inner arc is arranged, and another side is solid Surely there is the arc panel 440 being bent outwardly.So arc panel 440 the first strut 400 and the second strut strut cone section during, Tissue can be shelled to the direction far from the first strut 400 remote;The inner arc of first strut 400 is arranged Medical staff expands operative space.
In some embodiments, Fig. 8 is please referred to.Traversing portion is fixed with rectangular block 450, and the first strut 400 is configured with positive ten Two side shape slots 270, dodecagon slot 270 pass through the fixed rectangular block 450 of the opposite medial surface of its any two, the first strut 400 are fixed by bolt and traversing portion.
In some embodiments, operation panel 220 is fixed with motor, and the motor shaft of motor replaces manual pulley 243 and shaft 242 It is coaxial fixed.So medical staff can be realized and cone section is strutted and kept by exterior terminal driving motor.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
