In the embodiment, during specific operation, since the position of inserting the kirschner wire is variable, the position of the supporting rod 21 is likely to be difficult to contact and rotate, and therefore the universal joint 25 is added, so that the cross rod 23 can rotate relative to the supporting rod 21, and therefore, the needle bending operation is more convenient in actual work.
Further, the rotating assembly further comprises two rubber sleeves 26, and the two rubber sleeves 26 are fixedly connected with the cross rod 23 and are located on two sides of the cross rod 23.
In the present embodiment, the rubber sleeve 26 is mainly composed of rubber, and serves to increase friction between a user and the crossbar 23, thereby making it easier to rotate the crossbar 23.
The working principle and the using process of the invention are as follows: referring to fig. 1 and 2, after the present invention is installed, the kirschner wire 3 is withdrawn from the final depth by a certain distance by using the first clamping portion 111 and the second clamping portion 121 to prevent the kirschner wire 3 from penetrating the cortex, the groove 24 is engaged with the protruding column 14, the cross bar 23 is held by the other hand to rotate the supporting bar 21, the kirschner wire 3180 ° is bent under the action of the bending bar 22, then the first forceps handle 11 and the second forceps handle 12 are released, the cutting portion 15 is used to cut off the excess length of the kirschner wire 3, and finally the bent tail end of the kirschner wire 3 is knocked into the bone. Thus, after the tail end of the sharp kirschner wire 3 is embedded into the bone, the smooth hook part is flush with the bone surface.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
