Detailed description of the invention
Below by specific embodiment, detachable laminectomy rongeur of the present invention is described in further detail。
As shown in Figure 1, Figure 7 shows, detachable laminectomy rongeur, by upper slice 4, bottom sheet 5, branchia shaft screw and left clamp handle 1 form, the rear portion of bottom sheet 5 is the right clamp handle 2 matched with left clamp handle 1, by branchia shaft screw cross-articulation between right clamp handle 2 and left clamp handle 1, upper slice 4 front ends and bottom sheet 5 front end are provided with machinable cutting edge, upper slice 4 can slide along the longitudinal direction in bottom sheet 5, as shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5, the front end upper wall of described bottom sheet 5 is provided with front T type gib block 6, correspond, upper slice 4 front end lower wall on be provided with front T type gathering sill 7；Upper slice 4 rear end lower wall on be provided with after T-shaped gib block 8, correspond, the rear end upper wall of bottom sheet 5 is provided with after T-shaped gathering sill 9。As shown in Figure 6, the upper end of described left clamp handle 1 is provided with open slot 10, and described open slot 10 is the arcuate groove of opening upwards, as shown in Figure 4, upper slice 4 rear end be provided with bearing pin 11, bearing pin 11 is arranged in open slot 10。As shown in Fig. 1, Fig. 8, being provided with rotating limited block 12 on the front end face of described left clamp handle 1, limited block 12 is positioned at the angle of left clamp handle 1 and bottom sheet 5, and limited block 12 is strip, when the long end face of limited block 12 is not inconsistent with bottom sheet 5, bearing pin 11 can separate out from open slot 10 middle reaches。
Such as Fig. 9, Figure 10, Figure 11, shown in Figure 12, attachment structure between described limited block 12 and left clamp handle 1 is: be provided with spring base 13 in the front end face of left clamp handle 1, spring base 13 is connected with left clamp handle 1 by rivet 20, spring base 13 is provided with through hole, through hole is provided with spring catch 14, the outer cover of spring catch 14 is provided with spring 15, the hole wall of through hole is provided with step 16, the afterbody of spring catch 14 is provided with boss 17, the two ends of spring 15 are inconsistent with step 16 and boss 17 respectively, the front end of spring catch 14 is connected with limited block 12, the inner face of limited block 12 is provided with semicircular stopper slot 18, cooperating therewith, the front end of spring base 13 is semicircular limited post 19, it is spacing that limited post 19 is arranged in stopper slot 18 hoop realized between limited block 12 and spring base 13。
