122, the bottom end of the second shaft 122 is fixedly connected with the top of the second threaded post 13, passes through the second shaft 122 of setting and the second axis
121 are held, so that the rotation of the second threaded post 13 can drive the second shaft 122 to rotate in second bearing 121, so that being located at
The clamping plate 11 of lower section will not be rotated with the rotation of the second threaded post 13, to ensure underlying clamping plate 11 and second
Proper engagement work between threaded post 13,13 external screw thread of the second threaded post are connected with the second thread cap 14, the second thread cap 14
Left side be fixedly connected by supporting block 15 with the right side of fixed plate 8, the bottom end of the second threaded post 13 and the second handle 16
Upper surface be fixedly connected, by being provided with anti-skid chequer outside the second handle 16, so as to increase staff's palm and
Frictional force between two handles 16, so that staff is more convenient laborsaving by the second threaded post 13 of the second handle 16 rotation.
Operating procedure of the invention are as follows:
S1, when needing to dock two sections of diaphysis after patients with fractures, the present invention is first located above by medical staff
Two clamping plates 11 contacted respectively with two sections of diaphysis of patient, then the second handle 16 is rotated clockwise, so that 16 band of the second handle
Dynamic second threaded post 13 rotation, so that the second threaded post 13 passes through the second rotation under the threaded connection effect with the second thread cap 14
Rotary device 12 drives underlying clamping plate 11 to move up, when underlying clamping plate 11 and the diaphysis of patient are in close contact
When, staff rotates another the second handle 16 with same method again, allow four clamping plates 11 to two sections of diaphysis into
Row is fixed；
S2, when need two sections of diaphysis are docked when, staff rotates clockwise the first handle 5 again, so that first
Handle 5 drives the rotation of the first threaded post 4 by the first rotating device 3, so that two the first threaded posts 4 are in two the first thread caps
It is close to each other under 6 threaded connection effect, so that two the first thread caps 6 pass through two fixed plates 8 and several clamping plates respectively
11 drive two sections of diaphysis close to each other, and when two diaphysis docking are completed, stop operating the first handle 5, and doctor is made
It is fixed with diaphysis position of the tools such as bolt to patient；
S3, when doctor is fixed to diaphysis complete to need to remove the present invention when, staff first rotates counterclockwise the second handle
16, so that the second handle 16 drives the rotation of the second threaded post 13, so that the second threaded post 13 is in the screw thread with the second thread cap 14
It drives underlying clamping plate 11 to move down by the second rotating device 12 under connection function and is separated with patient's diaphysis, work
Personnel rotate another the second handle 16 with same method again, to remove the present invention.
Above-described specific embodiment has carried out further the purpose of the present invention, technical scheme and beneficial effects
It is described in detail, it should be understood that being not limited to this hair the foregoing is merely a specific embodiment of the invention
Bright, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should be included in the present invention
Protection scope within.
