As shown in FIG. 1, the present embodiment provides surgical shears including first handle 26 and second handle 36. The first handle 26 has a first extension 25. The second handle 36 has a second extension 35. First extension 25 and second extension 35 provide gripping support for a user of surgical shears 10. First extension 25 and second extension 35 allow the user to apply a force toward the proximal end of surgical shears 10 at the proximal end of surgical shears 10 to avoid slippage of the user's hands. Surgical shears 10 also include first resilient tab 28 and second resilient tab 38 positioned between first handle 26 and second handle 36. Surgical shears 10 are returned to their relaxed positions when not subjected to external forces by first resilient tab 28 and second resilient tab 38. The first handle 26 is connected to the second handle 36 by a first pivot assembly 40. As shown in FIG. 1, first handle 26 is also preferably connected to the proximal end of first head 20 at a second pivot assembly 42. The second handle 36 is connected to the proximal end of the second head 30 at a third pivot assembly 44.

Preferably, as shown in fig. 1 and 2, the first head 20 extends from the first handle 26 toward a distal end of the first head 20. The second head 30 extends from the second handle 36 toward the distal end of the second head 30. The distal ends of the first head 20 and the second head 30 are connected to a fourth pivot assembly 46 assembly. Preferably, the first pivot assembly 40, the second pivot assembly 42, the third pivot assembly 44 and the fourth pivot assembly 46 all include attachments. The accessories may include pins, screws, nuts and bolts, welds, or other combinations. The first insert 21 is part of the first head 20. The second blade 31 is part of the second head 30. Both the first head 20 and the second head 30 comprise a blade.

Preferably, as shown in fig. 1 and 2, when the first handle 26 and the second handle 36 are actuated, the first handle 26 and the second handle 36 rotate about the first pivot assembly 40. This rotation about the first pivot assembly 40 causes the distal ends of the first and second handles 26, 36 to separate, thereby causing the proximal ends of the first and second heads 20, 30 to separate by the second and third pivot assemblies 42, 44, and causing the first and second heads 20, 30 to rotate about the fourth pivot assembly 46. Rotation of the first and second heads 20, 30 moves the first and second blades 21, 31 toward each other, causing the first and second blades 21, 31 to cut through tissue or material located therebetween. First handle 26 and second handle 36 of surgical shears 10 are braked by the user pulling toward each other. The first handle 26 and the second handle 36 may be actuated with a single hand to provide greater flexibility to the user. First blade 21 and second blade 31 have cooperating shapes and are brought together by the braking of surgical shears 10. And surgical shears 10 may be returned to their relaxed positions by first resilient tab 28 and second resilient tab 38.

Preferably, as shown in fig. 3 and 4, the first header 20 includes a first connection portion 47. The first connector portion 47 is connected to the second connector portion 48 on the second head portion 30 to form the fourth pivot assembly 46. The first blade 21 is located at the distal end of the first head. A second blade 31 is located at the distal end of the second head 30. Preferably, the first blade 21 and the second blade 31 are rectangular. Or the edges of the first and second blades 21, 31 and blades may be a variety of shapes and sizes. For example, the first blade 21 and the second blade 31 may be circular or triangular. The resulting edge shape along the shaft may be a straight, notched or serrated blade. The distal ends of the first and second blades 21 and 31 may be convex or concave, which may make a straight cut or a wide-angle cut. The first and second cutting blades 21, 31 may be continuous or discontinuous. For example, the first and second blades 21 and 31 may extend along only three sides of a rectangle, such that there are no blades on the side near the first and second connection portions 47 and 48. In such an arrangement, the structure around the first connection portion 47 and the second connection portion 48 contributes to the formation of a capture space.

Preferably, as shown in fig. 5, the first blade 21 is inclined inwardly toward the first inner surface 23, and the second blade 31 is inclined inwardly toward the second inner surface 33. The angle of the first blade 21 and the second blade 33 is preferably about 40 ° to 50 °. The first blade 21 on the first head 20 and the second blade 31 on the second head 30 are shaped to interfit such that the first blade 21 and the second blade 31 are aligned when the first head 20 and the second head 30 are brought together. The first capturing space is defined by the first blade 21 and the first inner surface 23. The second catching space is defined by the second blade 31 and the second inner surface 33. When surgical shears 10 are braked, a capture space is formed between the blades and the inner surface. The capture space includes a first capture space and a second capture space. The first capture volume has a first depth and the second capture volume has a second depth. The distance from the edge of the first blade 21 to the first inner surface 23 is a first depth. The distance from the edge of the second blade 31 to the second inner surface 33 is a second depth. The first depth and the second depth preferably range from 0mm to 3 mm. The first depth and the second depth may be the same or different. Alternatively, the first blade 21 may be flat such that the first depth is 0 mm. Alternatively, the second blade 31 may be flat such that the second depth is 0 mm. The cut material, including crimped wire, suture knots or soft tissue, is held in the capture space and can be removed from the body. The capture space prevents the cut crimp portion of the wire from falling into the patient or flying away to injure medical personnel in the operating room. The capture space may accommodate tissue cut from the patient's body when desired, thereby facilitating further medical testing or testing of the tissue.

Preferably, as shown in fig. 6, surgical shears 10 include first and second blades 21, 31 at the distal ends of first and second heads 20, 30, which allow cutting at the distal ends of surgical shears 10. The first and second blades 21 and 31 may be placed around the crimped section 55 at the end of the wire 51 to separate the crimped section 55 from the wire 51. Crimped section 55 may be cut without placing surgical shears 10 at a wide angle with respect to the axis along wire 51. Alternatively, surgical shears 10 may cut crimped section 55 at a steep angle from the axis along crimped cable end 51. Another approach is to cut the crimped section 55 from the side, which may require a more invasive procedure and a larger incision. Direct cutting of the wire 51 requires only a small incision, which is beneficial for patient recovery.

For ease of understanding, the working principle of a surgical scissors will be discussed in detail.

In actual use, the first handle 26 and the second handle 36 of the surgical shears of the present invention are actuated by hand, such that the first handle 26 and the second handle 36 rotate about the first pivot assembly 40. This rotation about the first pivot assembly 40 causes the distal ends of the first and second handles 26, 36 to separate, thereby causing the proximal ends of the first and second heads 20, 30 to separate by the second and third pivot assemblies 42, 44, and causing the first and second heads 20, 30 to rotate about the fourth pivot assembly 46. The rotation of the first head 20 and the second head 30 moves the first blade 21 and the second blade 31 toward being closer to each other, causing the first blade 21 and the second blade 31 to cut through the article or material located therebetween. First handle 26 and second handle 36 of surgical shears 10 are braked by the user pulling toward each other. The distal ends of the first and second heads 20, 30 are brought together by first, second, third and fourth pivot assemblies 40, 42, 44, 46, the first and second blades 21, 31 having a shape that fits together and are brought together by the actuation of the surgical shears 10. Thereby closing the capturing space between the first head 20 and the second head 30. The cut material remains in the capture space, facilitating removal from the body. And surgical shears 10 may be returned to the relaxed position shown in fig. 1 by first resilient tab 28 and second resilient tab 38 without being subjected to external forces.
