Specific embodiment
Below in conjunction with attached drawing, the preferred embodiment of the utility model is described in detail.
Such as Fig. 1~8, a kind of bone plate external member convenient for taking nail, including bone plate 1, bone nail 2 and nail-fetching device 3;The synthetism
Several bone screw holes 11 are offered on plate 1, illustrate only two in such as 1;11 inside of bone screw holes is integrally formed with counterbore 12;Institute
Stating bone nail 2 includes nut 21 and stud 22;The diameter of the nut 22 is greater than counterbore 12 and is less than bone screw holes 11;The stud 22
Diameter be less than counterbore 12, offer ring-like through slot 4 between the bone screw holes 11 and bone plate 1, bone screw holes 11 and bone plate 1 are logical
Two bridge pieces 5 connection across ring-like through slot 4 is crossed, Fig. 5 and Fig. 6 can be combined to Fig. 2;The bridge piece 5 includes 51 He of bridge plate
The screw 52 in bone screw holes 11 and bone plate 1 is fixed at 51 both ends of bridge plate respectively, i.e. Fig. 3 and Fig. 4 can be combined to Fig. 2;It is described
Nail-fetching device 3 includes L-type handle 31, motor 32 and rotary-cut sword 33, such as Fig. 8;31 vertical section of L-type handle is arranged in the motor 32
Bottom inside, output shaft 321 stretch out L-type handle 31 and connect with rotary-cut sword 33;The rotary-cut sword 33 be in on output shaft 321
Side is close, downside is obliquely installed far from formula.
In use, being fitted in bone plate 1 above skeleton 6 across fracture line 7 such as Fig. 1, and will be connect by bone nail 2
Bone plate 1 is fixed on skeleton 6, specially utilizes such as screwdriver tool, nut 21 is sucked, and stud 22 is directed at counterbore
12, then rotary nut 21, until nut 21 is fitted on counterbore 12, to complete to fix, such as Fig. 7 guarantees to realize basic synthetism
Function.
When needing to take out bone plate 1, bone nail 2, if fractureing without bone nail or the situation of nut breakage, screw is directly utilized
The tools such as knife reversely back-out bone nail 2, so that it may remove bone plate 1.If bone nail occur to fracture or the situation of nut breakage, need
Nail, such as Fig. 9 are taken using nail-fetching device 3, motor 32 drives output shaft 321, and then rotary-cut sword 33 is driven to rotate, due to rotary-cut sword 33
Be obliquely installed as described above, therefore it can be tilted towards the stud 22 of bone nail 2 by ring-like through slot 4 and be cut, cut tight depth until
Stud 22 is almost switched to, it is then circumferentially cutting around ring-like through slot 4, until the skeleton 6 on 22 periphery of stud is all removed
Until, by bone nail 2 completely by removing in skeleton 6, then going out bone nail 2 with tool holders such as tweezers can be (thereon with a small amount of
Skeleton 6), bone plate 1 also can smoothly be taken out later.
To sum up, the utility model is on the basis of can be achieved basic bone-connecting functions, fractures or nut there is bone nail
When the situation of breakage, also very convenient bone plate and bone nail can be efficiently taken out.
Further, the rotary-cut sword 33 that the present embodiment uses is connect by shaft coupling 34 with the output shaft 321 of motor 32, such as
Fig. 8, the design can replace the rotary-cut sword 33 of differing tilt angles by shaft coupling 34, pierce depth to adapt to different bone nails 2
And crack conditions.When replacement, it may be considered that only replacement rotary-cut sword 33 can also set the rotary-cut sword 33 of different size to and join
34 one of axis device, i.e., replace rotary-cut sword 33 and shaft coupling 34 simultaneously.
Further, it is equipped with sawtooth (not shown) on the outside of the circumferential profile of rotary-cut sword 33 that the present embodiment uses, to mention
Rotary-cut effect of the high rotary-cut sword 33 to skeleton 6.
Further, power supply 35 is additionally provided in the L-type handle 31 that the present embodiment uses, the top of traversing section is equipped with button
36, such as Fig. 8, after surgical staff taking L-type handle 31, it can directly pass through thumb push button 36;Button 36 and power supply 35, electricity
Machine 32 is electrically connected, and can directly control the movement and stopping of motor 32, is arranged for conventional loop, therefore is not repeated its circuit knot
Structure.
Further, the lower section for 31 traversing section of L-type handle that the present embodiment uses is equipped with finger gripping groove 37, and such as Fig. 8, this is set
Meter can make to be not easy to skid when surgical staff taking L-type handle 31 more firm.
Finally, it is stated that preferred embodiment above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, to the greatest extent
Pipe has been described in detail the utility model by above preferred embodiment, but those skilled in the art should manage
Solution, can make various changes, without departing from the utility model claims book institute to it in the form and details
The range of restriction.
