Five, the specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of Wicresoft's shears under the scope of the present invention is described in detail.

Like Fig. 1, shown in 4; Wicresoft's shears under a kind of scope, it comprise movable blade 1, dead knife 2, movable knife bar 4, fixedly knife bar 2a, movable blade interlock pipe 3, operating grip 6, the mobile device that movable blade 1 is rotated fully tightly sting or open with dead knife 2, make movable blade 1 and dead knife 2 rotate the rot 5 that changes shear directions.

As shown in Figure 2, the binding clip of movable blade 1 and dead knife 2 couplings are coincide, and mobile device can make movable blade 1 and dead knife 2 sting fully tightly or open, and solid line is movable blade 1 open mode among the figure, and dotted line is for sting tight state fully among the figure.

As shown in Figure 4, operating grip 6 is the hollow circular cylinder of two ends perforate, and its outside is provided with two finger rings 7, inner by spring support ring 12 with its inner chamber separated into two parts, anterior packing movable blade interlock pipe 3, rear portion packing back-moving spring 9 and push rod 8; Push rod 8 front ends are provided with slide block 8b and support back-moving spring 9, and the rear end is provided with and pushes away handle 8a and stretch out operating grip 6.

Like Fig. 2,3, shown in 5, the pincers tail of dead knife 2 is connected with fixing knife bar 2a, and fixedly knife bar 2a penetrates movable blade interlock pipe 3; Movable blade interlock pipe 3 penetrates movable knife bar 4, and it is fixing to pass rotator 5, spring support ring 10, back-moving spring 9 backs and push rod 8.Movable blade interlock pipe 3 is than fixedly knife bar 2a and movable knife bar 4 are long, and the part that grows stretches in the operating grip 6 fixing with push rod 8.

As shown in Figure 3; The pincers tail of movable blade 1 has holder 1a, and holder 1a is a U-shaped, and its outside is fixed on the movable knife bar 4 with pin 1b and can rotates; Its inboard is that the U-shaped open side has fixture block 1c to snap in the bayonet socket 3a of movable blade interlock pipe 3 one ends; Like Fig. 6, shown in 7, bayonet socket 3a is bigger than fixture block 1c, and fixture block 1c can be rotated in bayonet socket 3a.Movable blade 2 can be rotated around pin 1b on movable knife bar 4.

Mobile device comprises movable blade interlock pipe 3, push rod 8, back-moving spring 9 and spring support ring 10.After promoting push rod 8, movable blade interlock pipe 3 is moved forward, rotate around pin 1b, open movable blade 1 with this thereby promote movable blade 1.Back-moving spring 9 is contained between spring support ring 10 and the push rod 8, make unclamp push rod 8 after, push rod 8 automatically resets, movable blade 1 is closed automatically.

As shown in Figure 4; Rot 5 is contained in operating grip 6 front ends and can rotates around it; Rot 5 is connected fixing with movable knife bar 4, as shown in Figure 8, has drive rod 5a to insert movable blade interlock pipe 3 in it and reaches fixedly knife bar 2a; Make the rotation of rot 5 can drive movable blade interlock pipe 3, movable knife bar 4 and fixedly knife bar 2a also rotate, change the shear direction of movable blade 1 and dead knife 2 with this.As shown in Figure 9, a long mouthful 3b is arranged on the movable blade interlock pipe 3, after being inserted, drive rod 5a can also in long mouthful 3b, move up and down, not influence moving up and down of movable blade interlock pipe 3.

During use, finger ring 7 lived by two glove and thumb is pinned push rod 8, Wicresoft's shears under the scope are stretched into patient's digestive tract; Like stomach, intestinal, esophagus etc., when its arrival needs digestive tract such as stomach, intestinal, esophageal cancer cell and the polyp of cutting, press and push away handle 8a; Movable blade 1 is opened, and another hands rotated device 5 makes edge of a knife aligning need the position of shearing; Unclamp thumb then, under the elastic force of back-moving spring 9, movable blade 1 beginning is drawn close toward dead knife 2 directions; Final movable blade 1 is stung tightly with dead knife 2 fully, cuts digestive tract such as stomach, intestinal, esophageal cancer cell and polyp.
