Hole 21, second rotary shaft 7 connect second rotary shaft 7 and sliding support 2 via the axis hole 21.
In the specific implementation process, it when Kirschner wire squeezes into fracture portions, generally requires so that two Kirschner wire fixations exist
In same plane.Cyclic annular fixing clamp 1 is fixed to the position of patient's fracture by doctor, and utilizes the first slide unit 4 and second
Sliding support 2 is slided along sliding rail 3 and slides into the corresponding position in direction for needing to squeeze into Kirschner wire by slide unit 5.First
Positioning lamp 11 and the second positioning lamp 12 are pointed into the position for needing to squeeze into Kirschner wire, utilize the first universal joint 13 and the 20000th
The position that the first positioning lamp 11 and the second positioning lamp 12 are adjusted to connector 14, when the first positioning lamp 11 and the second positioning lamp 12
When being irradiated to Kirschner wire and squeezing into the hot spot of position and be completely coincident, stop to the first universal joint 13 and the second universal joint 14
It controls and the first universal joint 13 and the second universal joint 14 is fixed so as to by the first positioning lamp 11 and the second positioning lamp
12 is fixed, it is worth mentioning at this point that, using the first universal joint 13 and the second universal joint 14 adjust the first positioning lamp 11 with
And second positioning lamp 12 position when, the adjustment of position, the first swivel plate 15 or the second rotation can be carried out to swivel plate component simultaneously
Rotating plate 16 carries out the restriction of lengthwise position to the first positioning lamp 11 and the second positioning lamp 12, when the first swivel plate 15 or the second rotation
When rotating plate 16 is rotated, drives to be used as the first swivel plate 15 of current active rotation plate or the second swivel plate 16 and work as preshoot
The second swivel plate 16 or the first swivel plate 15 of dynamic swivel plate rotate corresponding angle and position.Utilizing the first positioning lamp 11
And second positioning lamp 12 location confirmation is squeezed into Kirschner wire after, doctor controls rotary shaft body 8 for Kirschner wire propeller 9 towards grams
Family name's stylus printer enters at the hot spot of position, and Kirschner wire is squeezed into the corresponding position of hot spot by Kirschner wire propeller 9.
After current Kirschner wire is squeezed into, by the second stud shaft 20 from the through-hole 18 of the baffle 17 of the second slide unit 5
It takes out, the junction of the second slide unit 5 and sliding rail 3 is in open state at this time, and by the second sliding part under open state
Part 5 is rotated around the second rotary shaft 7, so that the second slide unit 5 is detached from sliding rail 3, at this point, the first slide unit 4 and first
Stud shaft 19 is in stationary state, and entire sliding support 2 is rotated 180 ° around the first rotary shaft 6 by doctor, to drive sliding branch
Component on frame 2 rotates 180 °, so control the first positioning lamp 11 and the second positioning lamp 12 around the first universal joint 13 with
And second at the rotation to current corresponding driven swivel plate of universal joint 14 and be close to follower plate, it is worth mentioning at this point that, to the
When one positioning lamp 11 and the second positioning lamp 12 are adjusted, only for the vertical of the first positioning lamp 11 and the second positioning lamp 12
It is changed to position without changing lateral position, since current driven swivel plate is consistent with the angle of active rotation plate, because
This spatially sees that current driven swivel plate is in same plane with active rotation plate when not rotating, therefore, is close to
First positioning lamp 11 of current driven swivel plate and the second positioning lamp 12 be close to the first of active rotation plate when not rotating
Positioning lamp 11 and the second positioning lamp 12 are in same plane, therefore, along the first positioning lamp 11 in same plane
And second positioning lamp 12 irradiate the Kirschner wire that the obtained direction of hot spot is squeezed into and be also in same plane.
Embodiment two:
It is Fig. 6-8 with reference to figure.As a kind of preferred embodiment of the invention, the crossbeam of the sliding support 2 further includes threaded hole 22
And the bolt 23 that is screwed, the bolt 23 that is screwed fix the position of the rotary shaft body 8 via the threaded hole 22.

Portion size is consistent with 9 external dimensions of Kirschner wire propeller, and the cyclic structure inner wall is provided with several L-type grooves 24.
As a kind of preferred embodiment of the invention, 9 side of Kirschner wire propeller is provided with several convex blocks 25, described convex
25 quantity of block is consistent with 24 quantity of L-type groove, and 25 size of convex block suits with the L-type groove 24.
As a kind of preferred embodiment of the invention, the Kirschner wire propeller 9 further includes cylinder base 26, cylinder 27, telescopic shaft
28, rotating through hole axis 29, motor 30, the motor 30 are separately connected the telescopic shaft 28 and rotating through hole axis 29, the electricity
Machine 30 is set to the cylinder base 26, and the telescopic shaft 28 connects the rotating through hole axis 29, and the rotating through hole axis 29 is for putting
Set Kirschner wire.
In the specific implementation process, after Kirschner wire is put into Kirschner wire propeller 9, by 9 outside of Kirschner wire propeller
Convex block 25 be directed at the port of L-type groove 24, and promote in L-type groove 24, push away Kirschner wire when being pushed into L-type 24 bottom of groove
It is rotated into device 9 to side, convex block 25 is caught in the side of L-type groove 24.When according to the first positioning lamp 11 and the second positioning lamp
When the propulsion position of 12 confirmation Kirschner wire propellers 9, the bolt 23 that will be screwed is screwed in threaded hole 22, and is threaded to most tightly, thus
Rotary shaft body 8 and the relative position of the crossbeam of sliding support 2 are fixed, prevent the feelings shifted occur when promoting Kirschner wire
Condition.When Kirschner wire propeller 9, which reaches, squeezes into position, doctor control motor 30 open, motor 30 control telescopic shaft 28 stretch out with
And rotating through hole axis 29 rotates, to drive Kirschner wire to rotate and stretch out along the direction of setting, to Kirschner wire be squeezed into pre-
Fixed position.
The above embodiments merely illustrate the technical concept and features of the present invention, and the purpose is to allow the skill for being familiar with the technical field
Art personnel can understand the content of the present invention and implement it accordingly, and can not be limited the scope of the invention with this.All bases
Equivalent changes or modifications made by spirit of the invention, should be covered by the protection scope of the present invention.
