The surface configuration of horizontal location post 1 has a centimetre scale for meter.When horizontal location groove 11 is vertical with perpendicular positioning groove 211 When intersecting, can accurately be measured the water position of hollow nail guide pin 9 by scale herein, it is simple to be accurately positioned.
Perpendicular positioning assembly 2 includes fixing bar 22, sliding part 6 and at least perpendicular positioning post 21, fixing bar 22 one end Being rotatably connected with support 3, sliding part 6 is sheathed on fixing bar 22, and sliding along fixing bar 22 is arranged, and the upper end of perpendicular positioning post 21 is solid Due to sliding part 6, perpendicular positioning post 21 offers perpendicular positioning groove 211 vertically.The lower end of perpendicular positioning post 21 is fixed with level Position post 1 intersects, and is arranged at the horizontal location groove 11 of horizontal location post 1 and is arranged at the perpendicular positioning groove 211 of perpendicular positioning post 21 It is crossed to form guide pinhole.
In the present embodiment, perpendicular positioning post 21 is provided with two, and two perpendicular positioning posts 21 are arranged side by side.
Perpendicular positioning assembly 2 also includes indicating arm 24, and perpendicular positioning post 21 is connected with sliding part 23 company turn, vertically fixed Position part 21 rotates around axle center, and indicating arm 24 is arranged at sliding part 6, and with perpendicular positioning post 21 drive connection, drive described vertically Locating dowel 21 rotates.Indicating arm 24 and perpendicular positioning post 21 drive connection, can adjust vertical by adjusting the position of indicating arm 24 The angle of straight locating dowel 21, changes the direction corresponding to notch of perpendicular positioning groove 211, can be cheer and bright by indicating arm 24 The notch direction understanding locating slot, namely know the direction that hollow nail guide pin 9 is implanted.Thereby indicate that bar 24 has adjustment vertically The notch direction of locating slot 211 and instruction hollow nail guide pin 9 implant the function in direction.
Sliding part 23 upper surface is provided for measuring and the goniometer 25 of instruction perpendicular positioning post 21 anglec of rotation, passes through angle Degree meter can accurately measure the rotational angle of indicating arm 24 and indicated direction, and then controls the anglec of rotation of perpendicular positioning post 21 Degree, it is simple to the notch direction of perpendicular positioning groove 211 is accurately positioned.
Sliding part 6 arranges locking mechanism, and the locking mechanism locking sliding part 6 of sliding part 6, in the position of fixing bar 22, has The effect of anti-skidding location, the locking mechanism of sliding part 6 can also be locked indicating arm 24 and perpendicular positioning post 21, be prevented indicating arm 24 He Perpendicular positioning post 21 rotates.
The surface of support 3 is axially disposed a centimetre meter scale.Existed by centimetre meter flat locating dowel of scale measure water 1 Position on support 3, it is simple to be accurately positioned horizontal location post 1.
Fixing bar 22 surface is axially disposed a centimetre meter scale.A centimetre meter scale is set and can accurately measure perpendicular positioning post 21 positions on fixing bar 22, it is simple to be accurately positioned perpendicular positioning post 21.
Pedestal 4 arranges track 7 and slide block 8, and slide block 8 slides along track 7 and arranges.The lower end of support 3 rotates even with slide block 8 Connecing, around the axle center rotary setting of support 3, support 3 is followed slide block 8 and is slided along track 7, the perpendicular positioning assembly 2 of the present embodiment with The rotation of support 3 and rotate, mobile with the movement of support 3.Slide block 8 arranges locking mechanism, and the locking mechanism by slide block 8 can The locking sliding block 8 position on track 7, and lock bracket 3, anti-limited slip block 8 slides, and prevents support 3 from rotating.Patient lies at hands During art platform, removing patient extremely onerous, and action easily adds too greatly the condition of the injury of heavy patient, is unfavorable for treatment, arranges slip rail Road 7, it is extremely simple that mobile interior fixing auxiliary determines system, it is simple to finds the implantation position of hollow nail guide pin 9 accurately.The additionally health of patient Skeleton is not all parallel with pedestal, it is impossible to ensure that perpendicular positioning assembly 2 horizontal location assembly is all fitted the health of patient, different Operation will produce different hollow nail guide pin 9 implantation positions, support 3 is rotatably connected with pedestal, can be by swinging mounting 3 Adjust the laminating angle of perpendicular positioning assembly 2 and horizontal location assembly and health.
Fig. 3, Fig. 4 are the schematic diagram that the present embodiment is under hollow nail guide pin 9 state of location, in use, first rotate Support 3 makes perpendicular positioning post 21 near the health of patient, and mobile slide block 8 makes perpendicular positioning, post 21 move to need to implant steel nail Position, locking sliding block 8 and support 3;Then rotate horizontal location post 1, make horizontal location post 1 and perpendicular positioning post 21 intersect; Moving the position of perpendicular positioning post 21 and lock, determining the position of the horizontal direction implanting point, mobile and horizontal locating dowel 1 is at support Position on 3 is also locked, and determines the position of the vertical direction implanting point, rotates indicating arm 24, adjusts vertically according to goniometer 25 The notch direction of locating slot 211, controls the implantation direction of hollow nail guide pin 9, and locks indicating arm 24.Implant some position and implantation Direction all determines, and doctor just can be easily according to leading that horizontal location groove 11 and perpendicular positioning groove 211 are formed after staggered Pin hole carries out hollow nail guide pin 9 and implants.
The present embodiment perpendicular positioning assembly 2 rotates also by other modes, as it is shown in figure 5, fixing bar 22 one end is sheathed In support 3, around support 3 rotary setting, support 3 upper end arranges the second retaining mechanism 6, and the second retaining mechanism 6 is locked bar 22 With being rotatably connected of support 3, prevent fixing bar 22 from rotating when operation.The lower end of support 3 and slide block 8 is fixing to be connected, support 3 with Slide along track 7 with slide block 8.Slide block 8 arranges locking mechanism, by the locking mechanism of slide block 8 can locking sliding block 8 on track 7 Position.
It is prevented from hand-held when hollow nail guide pin 9 is implanted rocking by fixing aided positioning system in the present embodiment, plants Entering position and direction is not hit power and the impact of sclerotin and offsets, effective auxiliary doctor is accurately positioned sky in bone surgery Heart nail guide pin 9, disposably completes hollow nail guide pin 9 implant procedure, accelerates the implantation speed of hollow nail.
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, Any those familiar with the art in the technical scope that the invention discloses, the change that can readily occur in or replacement, All should contain within protection scope of the present invention.Therefore, protection scope of the present invention should be with scope of the claims It is as the criterion.
