This utility model has the advantage that relative to prior art
1, this utility model is applicable to need when abdominal cavity and pelvic irradiation the situation of straddle, trapezoidal hole is outputed at positioning board for radiotherapy straddle position, two radiotherapy film edge strips are respectively placed in the waist of trapezoidal hole, then the slide block of edge strip slide rail type retaining mechanism slides along guide rail toward cephalad direction, the both sides of slide block are parallel with the two of described trapezoidal hole waists respectively, make use of slide block both sides gradually approaches effect, the both sides of slide block and the two of trapezoidal hole waist clamping radiotherapy film edge strips, thus realizes the most fixing radiotherapy film edge strip；When location or radiotherapy terminate, exit slide block backward, take out two radiotherapy film edge strips, radiotherapy membrane modle can be taken off.Design of the present utility model, once-through operation can fix two radiotherapy film edge strips, need not operate respectively, single can complete, avoid hand steered a radiotherapy film edge strip, another hands looks for and places the trouble of rectangle card article, avoids existing design operation overlong time simultaneously and causes moulding failed defect, it also avoid rectangle card article and separate the defect easily lost and break with positioning board for radiotherapy.
2, the base of trapezoidal hole connects with the top of rectangular opening, and the base length of side of trapezoidal hole is more than the top length of side of rectangular opening, when such structure makes the waist that radiotherapy film edge strip puts into trapezoidal hole, has a positioning action, will not slide along waist.
3, the upper surface of slide block and the upper surface of positioning board for radiotherapy are concordant, compact attractive in appearance.
4, the top thickness of guide rail is more than end thickness, and guide rail top ratio is relatively thin, is placed and taken out slot milling for radiotherapy film edge strip.
5, the bottom surface of slide block is provided with a pair location claw, the lower end inside of location claw is provided with arc convex, the both sides of guide rail have two pairs of arc positioning grooves, start of a run and final position at slide block, location claw snaps in arc positioning groove, this ensures that thering slide block will not arbitrarily slide when start of a run, slide block will not loosen when stroke end.
6, the bottom surface of slide block is provided with two pairs of L position-limited claws, and every a pair position-limited claw direction is relative, and the both sides, bottom surface of guide rail have gathering sill, and position-limited claw embeds gathering sill, it is ensured that slide block will not upwards be routed up.
7, the two ends of the moving direction of slide block upper surface are provided with arc finger position, it is simple to finger pinches and has an effect.
8, the bottom surface of positioning board for radiotherapy, is provided with, in two waist positions of trapezoidal hole, the step caught on for the base of radiotherapy film edge strip, and this step goes for the structure of existing radiotherapy film edge strip, it is not necessary to redesign radiotherapy film edge strip.
