The specific embodiment
Below in conjunction with accompanying drawing and embodiment this utility model is further described:
Are
like figure? Shown a kind of multifunctional orthopaedics exterior fixation bracket; Comprise connecting rod 1, be movably connected in shank fixation clamp 2 on the connecting rod 1, offer the folder pin piece 3 of folder pin hole 30, shank fixation clamp 2 passes through pillar 4 with folder pin piece 3 and flexibly connects mutually.
Below specifically each parts are carried out detailed description:
The pin gear ring 21 that
shank fixation clamp 2 comprises upper tube cap 20, is complementary with upper tube cap 20 forms first connecting portion 22 of connecting struts 4 between upper tube cap 20 and the pin gear ring 21; Lower tube cap 23, the pipe gear ring 24 that is complementary with lower tube cap 23; Form second connecting portion 25 that connects connecting rod 1 between pipe gear ring 24 and the lower tube cap 23; Upper tube cap 20, pin gear ring 21, pipe gear ring 24 and lower tube cap 23 are fastened through screw 26 successively; And be provided with spring 27 between pin gear ring 21 and the pipe gear ring 24, and the contact surface of pin gear ring 21 and pipe gear ring 24 is the flank of tooth.What connecting rod 1 can rotate and slide is fastened in second connecting portion 25; What pillar 4 also can rotate and slide is fastened in first connecting portion 22; Confirm to lock through screw 26 behind the correct position; Because the setting of spring 27 makes connecting rod 1 and pillar 4 put into conveniently and can not skid off, both locking is also guaranteed in the flank of tooth of contact surface design simultaneously.
