Example (b):

referring to fig. 1, 2, 3, 4 and 5, a jaw stripper for cosmetic plastic surgery comprises a handle bar 1, wherein a plurality of anti-slip protrusions 16 are uniformly distributed on the outer side wall of the handle bar 1 of the embodiment, so that an operator can hold the device conveniently. Be equipped with in handle bar 1 and accept chamber 2, accept chamber 2 and set up along handle bar 1's length direction, the both ends of accepting chamber 2 all are equipped with the perforation 3 of wearing out handle bar 1's both ends, and the cross sectional area who perforates 3 is less than the cross sectional area who accepts chamber 2, accepts and is equipped with the connecting block 4 that the inner wall laminating of lateral wall and accepting chamber 2 and can remove along the length direction who accepts chamber 2 in the chamber 2, and connecting block 4 can not the roll-off perforation 3.

Both ends of connecting block 4 all are equipped with the accessible and perforate 3 and move into the connecting rod 5 of acceping in 2 chambeies, connecting rod 5 and connecting block 4 welding, the tip that two connecting rods 5 deviate from connecting block 4 is equipped with respectively all to accept straight blade 6 and the blade 7 of buckling in 2 chambeies with the common immigration of connecting rod 5, the tip that deviates from connecting rod 5 is all located to straight blade 6 and the cutting edge of buckling blade 7, straight blade 6 is used for peeling off the musculature of mandible leading edge perpendicularly, the radian of buckling of blade 7 can be designed according to the radian of mandible lower edge and trailing edge, 7 protractile mandible lower edges and trailing edges of buckling blade, thereby the more convenient musculature of peeling off mandible lower edge and trailing edge.

The lateral wall of connecting block 4 is equipped with the push rod 8 that stretches out handle bar 1, and push rod 8 welds with connecting rod 5, and the lateral wall of handle bar 1 of push rod 8 side is equipped with along the length direction setting of handle bar 1 and supplies the draw runner hole 9 that push rod 8 passed, and the accessible promotes push rod 8 and will straighten blade 6 and buckle blade 7 roll-off or slide into accept in the chamber 2. The push rod 8 is equipped with the slide 10, the slide 10 sets up along the direction of the push rod 8 perpendicular to handle bar 1, be equipped with slider 11 in the slide 10, the tip that slider 11 deviates from slide 10 is equipped with convex fixed block 12, convex fixed block 12 and slider 11 welding, convex fixed block 12 is equipped with card 13 towards the one side of handle bar 1, the both ends of handle bar 1 all are equipped with the draw-in groove 14 with the protruding 13 block of card, slider 11 can move to handle bar 1 along slide 10, accessible card 13 and draw-in groove 14 are fixed connecting block 4, when preventing to cut muscle soft tissue, connecting rod 5 removes. The circular ring 15 is arranged on one side, away from the clamping protrusion 13, of the circular arc fixing block 12, the circular ring 15 is welded with the circular arc fixing block 12, when an operator replaces blades at two ends, the circular ring 15 can be lifted by fingers, the circular arc fixing block 12 is separated from the handle rod 1 by one hand, and the other hand of the operator can continue previous operation conveniently.

The shape of blade 7 of buckling is isosceles trapezoid, and the longer limit in two limits that blade 7 of buckling is parallel to each other links to each other with connecting rod 5, and the blade of blade 7 of buckling is located the shorter limit in two limits that blade 7 of buckling is parallel to each other, and when handle bar 1 was the cylinder size, isosceles trapezoid's blade 7 of buckling more can increase the length of blade 7 of buckling than square blade 7 of buckling.

The utility model discloses a theory of use as follows: when the surgical knife is used, the push rod 8 is pushed, the connecting rod 5 on the side where the straight blade 6 is located is pushed out of the accommodating cavity 2 and the through hole 3, then the arc-shaped fixing block 12 is moved, the clamping protrusion 13 is clamped with the clamping groove 14, and therefore the connecting block 4 is fixed, and surgical operation is conducted; when muscle soft tissue at the lower edge and the rear edge of a mandible needs to be cut, an operator lifts the ring 15 with one finger to separate the arc-shaped fixing block 12 from the handle rod 1, stirs the push rod 8, slides the straight blade 6 and the connecting rod 5 at the side of the straight blade 6 into the accommodating cavity 2, moves the bending blade 7 and the connecting rod 5 at the side of the bending blade 7 out of the accommodating cavity 2 and the through hole 3, and moves the arc-shaped fixing block 12 again when the connecting block 4 moves to one end, close to the bending blade 7, of the accommodating cavity 2, so that the clamping protrusion 13 at the side is clamped with the clamping groove 14.
