Description
Technical field
This utility model relates to a kind of pedicle of vertebral arch device for taking out broken nail, belongs to technical field of medical instruments.
Background technology
At present, in spinal surgery, the use of pedicle nail is very extensive, after pedicle nail is squeezed into, due to factors such as stress, often can rupture, and broken nail is stayed in bone, brings impact to patient's health, even causes operative failure.Going out of broken nail is comparatively loaded down with trivial details, once taking-up mode is improper, easily patient is caused to secondary injury, increases patient's misery.Existing device for taking out broken nail exposes nail tail, then is counter-rotated taking-up after normally broken nail sclerotin around being removed, because pedicle nail is when inserting, comparatively strict to the requirement of angle, if when taking out removing direction and placing direction inconsistent, easily cause the secondary injury of sclerotin.
Utility model content
According to above the deficiencies in the prior art, technical problem to be solved in the utility model is: a kind of pedicle of vertebral arch device for taking out broken nail is provided, and simple in structure, reasonable in design, broken nail interlock is firm, can accurately along placing direction, take out broken nail, avoid sclerotin to cause secondary injury, guarantee operation safety.
Pedicle of vertebral arch device for taking out broken nail described in the utility model, comprise bearing rod, bearing rod lower end junction button pawl, bearing rod upper end connecting handle, bearing rod outside is provided with sleeve, sleeve bottom is against buckles pawl outside, and sleeve top is provided with pedestal, and pedestal top is provided with the nut being threaded with bearing rod, sleeve outside cover has rotary sleeve, rotary sleeve is arranged on positioning table, and positioning table one side is provided with angle board, and corresponding rotary sleeve is provided with pointer.
By sleeve is set, when swivel nut, sleeve is descending, and compressing button dog clutch closes, thereby makes to detain the tight broken nail of dog clutch.Pass through rotary sleeve, sleeve can be swung on positioning table, rotary sleeve is followed sleeve and is swung, its amplitude of fluctuation is consistent with sleeve, by the pointer on rotary sleeve, can read the rotation amplitude of sleeve relative localization platform, thereby can learn the axis angle of bearing rod, by definite reference angle degree of positioning table, then by changing the axis angle of bearing rod, make its with pedicle nail to insert angle consistent, thereby the back-out direction of guaranteeing broken nail is consistent with placing direction, make to get nail and be more prone to, avoid causing secondary injury simultaneously, guarantee operation safety.
Described bearing rod initial position is vertical with positioning table, and corresponding pointer refers to that in 0 ° of position of angle board, the reference position of positioning table overlaps with 0 ° of position, when holding vertical rod deflection, can directly read deflection angle.
Described angle board minimum scale is 2 °, can determine and get nail angle comparatively accurately.
Described button pawl bottom is provided with bite, bite is inwardly protruding arc tip, by bite, bite the afterbody of broken nail, tip can be easy to insert in thread pitch, thereby guarantees interlock dynamics, and, compare and traditional nail-fetching device, do not need to sweep off the sclerotin part of broken nail afterbody, reduce sclerotin clearing amount, be conducive to patient health.
Described button pawl is along circumferentially arranging, and quantity is 3～4.
According to the angle of inserting of the position of the definite broken nail of film making and broken nail, while getting nail, first broken nail afterbody is carried out to conventional processing, remove sclerotin part, the bite of button pawl bottom is placed on to broken nail afterbody, rotating nut, nut promotes sleeve by pedestal and moves down, in the descending process of sleeve, will buckle gradually pawl locking, thereby bite is fixedly secured at broken nail afterbody.By positioning table, determine datum level, the bearing rod that swings, adjusts the angle of bearing rod by total indicator reading, make bearing rod and broken nail insert angle consistent, and turning handle takes out broken nail.
Compared with prior art, the beneficial effect the utlity model has is:
This pedicle of vertebral arch device for taking out broken nail is by arranging angle board, and making bearing rod get nail direction and broken nail, to insert angle consistent, makes to get nail operation and be more prone to, and avoids patient to cause secondary injury assurance operation safety simultaneously; By button pawl and bite, avoid clear a large amount of sclerotin, be conducive to patient health.
Accompanying drawing explanation
Fig. 1 makes this utility model structural representation;
In figure: 1, hands handle; 2, bearing rod; 3, nut; 4, pedestal; 5, sleeve; 6, positioning table; 7, button pawl; 8, bite; 9, rotary sleeve; 10, angle board; 11, pointer.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1, this pedicle of vertebral arch device for taking out broken nail comprises bearing rod 2, bearing rod 2 lower end junction button pawls 7, button pawl 7 is along circumferentially arranging, quantity is 3～4, and preferably 3, button pawl 7 has segmental arc and the straight section coordinating with sleeve 5, button pawl 7 bottoms are provided with bite 8, bite 8 is inwardly protruding arc tip, by bite 8, bites broken nail afterbody, because bite 8 volumes are little, gmatjpdumamics is strong, therefore only needs to clear up broken nail fraction sclerotin around.Bearing rod 2 upper end connecting handles 1, bearing rod 2 outsides are provided with sleeve 5, sleeve 5 bottoms are against buckles pawl 7 outsides, sleeve 5 tops are provided with pedestal 4, pedestal 4 tops are provided with the nut 3 being threaded with bearing rod 2, and pedestal 4 is integrated with sleeve 5, and nut 3 is split with pedestal 4, split-type structural is for convenience detach and be mounted to, and avoids sleeve 5 phase make-up pawls 7 rotations to cause buckle pawl 7 wearing and tearing simultaneously.
Sleeve 5 outside covers have rotary sleeve 9, rotary sleeve 9 to be arranged on positioning table 6, and positioning table 6 one sides are provided with angle board 10, and corresponding rotary sleeve 9 is provided with pointer 11, and angle board 10 minimum scales are 2 °.Bearing rod 2 initial positions are vertical with positioning table 6, and corresponding pointer 11 fingers are in 0 ° of position of angle board 10.
Work process:
According to the angle of inserting of the position of the definite broken nail of film making and broken nail, while getting nail, first broken nail afterbody is carried out to conventional processing, remove sclerotin part, the bite 8 of button pawl 7 bottoms is placed on to broken nail afterbody, rotating nut 3, nut 3 promotes sleeve 5 by pedestal 4 and moves down, in the descending process of sleeve 5, will buckle gradually pawl 7 lockings, thereby bite 8 is fixedly secured at broken nail afterbody.By positioning table 6, determine datum level, the bearing rod 2 that swings, the angle by pointer 11 readings adjustment bearing rods 2, makes bearing rod 2 and broken nail insert angle consistent, and turning handle 1 takes out broken nail.
