As shown in fig. 2, the first rear section 130 is provided with an elongated slot 330; elongated slot 330 extends along the length of first shear body 100; the opening of the long slot 330 faces the second scissor body 200; a first steel cable 340 is fixedly connected to the inside of one end of the long slot 330 near the first hinge segment 120.

As shown in fig. 2, an intermediate section 310 is formed at the second rear section 230; the middle section 310 is a cylinder, and the second rear section 230 is a rectangular cylinder; the diameter of the middle section 310 is smaller than either side of the cross-section of the second rear section 230, so that the middle section 310 does not interfere with contact between the first rear section 130 and the second rear section 230; a broken wall 350 is formed at the intersection of the two ends of the middle section 310 and the second rear section 230 (i.e. the cross section formed at the intersection, the broken wall 350 is perpendicular to the length direction of the second rear section 230); the middle section 310 is provided with a sliding sleeve 320, and the sliding sleeve 320 is provided; the other end of the first steel cable 340 is fixedly connected to the sliding sleeve 320.

As shown in fig. 2 and 3, the second tail section 240 is provided with a groove 410; the opening of the groove 410 faces the side away from the first shear body 100; the second scissors body 200 is further provided with a through hole 370 (specifically, the through hole is provided with a second rear section 230 and a second tail section 240); the through hole 370 extends in the length direction of the second scissor body 200; one end of the through hole 370 penetrates the groove 410; the other end of the through hole 370 penetrates the partition wall 350.

As shown in fig. 2 and 3, a rotary table is rotatably embedded in the groove 410; the rotating disc comprises an inner shaft 420 and an outer disc 430 which are coaxially fixedly connected with each other; the inner shaft 420 is located inside the groove 410; the outer plate 430 partially protrudes out of the groove 410; the inner shaft 420 is wound with a second steel rope 360; the other end of the second steel cable 360 is inserted into the through hole 370 and connected to the sliding sleeve 320.

The edge of the outer disc 430 is provided with a plurality of clamping grooves 431 which are uniformly distributed in the circumferential direction; as shown in fig. 3 and 4, a convex groove 440 is formed on a side of the second tail section 240 away from the first tail section 140; one end of the convex groove 440 penetrates the groove 410; a clamping plate 450 is movably embedded in the convex groove 440; a spring 470 is connected between one end of the clamping plate 450 and the inner end of the convex groove 440; the other end of the clamping plate 450 extends into the groove 410 by the elastic force of the spring 470, and the other end of the clamping plate 450 can be embedded into the clamping groove 431; the clamping plate 450 is also connected with a shifting lever 460 perpendicular to the clamping plate 450; the shift lever 460 extends out of the protrusion groove 440.

The utility model provides a surgical scissors can realize that the angle of restriction opening angle and the limited opening angle can be adjusted as required, it is concrete, when the opening angle needs to be adjusted, through stirring driving lever 460, make cardboard 450 withdraw from draw-in groove 431, then the rotating chuck, adjust the length of second steel cable 360 with this, thereby restrict the slidable distance of sliding sleeve 320 at interlude 310, and be connected with first steel cable 340 on the sliding sleeve 320, the other end of first steel cable 340 is connected in the inside of the elongated slot 330 of first back end 130, the slidable distance of sliding sleeve 320 on interlude 310 has actually restricted the relative second of first scissors body 100 and has cut the angle that the body 200 can open, thereby the opening angle of whole surgical scissors has been restricted.

For example, when a larger opening angle is needed, the chuck is simply rotated to extend the second wire cable 360, so that the sliding sleeve 320 can slide to a region closer to the second hinge segment 220, and thus the relatively-openable angle between the first scissors body 100 and the second scissors body 200 is larger; when a small opening angle is needed, the chuck is only required to be rotated to shorten the second steel wire 360, so that the slidable distance of the sliding sleeve 320 is shortened, and the angle at which the first shear body 100 and the second shear body 200 can be relatively opened is reduced; when the opening angle is adjusted, the lever 460 is released, and the catch plate 450 is inserted into the catch groove 431 of the chuck by the spring 470 to fix the chuck, thereby limiting the slidable distance of the sliding sleeve 320, and thus completing the fixation of the opening angle of the surgical scissors.

In addition, the length of the first steel cord 340 is set to enable the sliding sleeve 320 to slide to contact with any one of the break walls 350; however, the length of the first steel rope 340 cannot be too long, or the opening angle limiting function is lost, in this embodiment, the length of the first steel rope 340 is preferably such that when the sliding sleeve 320 slides to contact with the broken wall 350 (the broken wall 350 near the second tail segment 240), the first steel rope 340 is straightened, and at this time, the first rear segment 130 is in contact with the second rear segment 230. Meanwhile, the sliding sleeve 320 is a circular sleeve, and the outer diameter of the sliding sleeve 320 does not exceed the length of the cross section of the second rear section 230, that is, the sliding sleeve 320 does not interfere the contact between the second rear section 230 and the first rear section 130.

Meanwhile, when the first tail section 140 and the second tail section 240 are in close contact, the first cutter body 110 and the second cutter body 210 are in close contact, and the first rear section 130 and the second rear section 230 are in close contact, which is arranged to ensure the hand feeling of the surgical scissors in use (i.e. the first scissors body 100 and the second scissors body 200 can be integrally attached at the same time).

Further, as shown in FIG. 2, the length of the elongated slot 330 is greater than the length of the intermediate segment 310; when the first rear section 130 is in abutting contact with the second rear section 230, the intermediate section 310 is within the length of the slot 330. The function of the elongated slot 330 is in fact to receive the first steel cord 340 when the first rear segment 130 and the second rear segment 230 are in abutting contact with each other, preventing the first steel cord 340 from interfering with the contact between the first rear segment 130 and the second rear segment 230; similarly, by the above technical solution, no matter where the sliding sleeve 320 is located on the middle section 310, the first steel cable 340 can be received in the long slot 330, so as to further ensure that the contact between the first rear section 130 and the second rear section 230 is not interfered.

Meanwhile, as shown in fig. 3, the catching groove 431 extends in a radial direction of the outer disk 430. With such an arrangement, the outer disk 430 is better limited when the clamping plate 450 is embedded into the clamping groove 431.

Further, the first blade 100 and the second blade 200 are made of stainless steel, and in this embodiment, 304 stainless steel is preferable, which is hard, excellent in durability and corrosion resistance, and suitable for use as surgical scissors.

Meanwhile, as shown in fig. 1, the first tail section 140 is provided with a first handle 150; the second tail section 240 is provided with a second handle 250; first handle 150 and second handle 250 are oppositely disposed. The interior of first handle 150 and the interior of second handle 250 are both rounded to facilitate grasping. And the inner walls of the first handle 150 and the second handle 250 are provided with anti-slip rubber rings (not shown) around to improve the anti-slip capability.
