[0021] The present invention will be further described below:

[0022] Please see Figure 1-5 ,

[0023] This utility model discloses a transverse-pulling surgical scissors for gynecological surgery, such as... Figure 1 and Figure 2 As shown, the surgical scissors include a blade 1, a handle 3, a hinge bolt 2, and a handle ring 4. The top rear sides of the two blades 1 are hinged by the hinge bolt 2. The front ends of the two handles 3 are respectively connected to the rear ends of the two blades 1. The two handles 3 are provided with handle rings 4 that can move along their length. The handle rings 4 can move along the length of the handle 3, so that the two fingers passing through the handle rings 4 will not make contact obstruction when cutting during the operation, thereby improving the smoothness of cutting with surgical scissors. The handle rings can also be adjusted to the preferred position according to the usage habits of different medical staff. The front ends of the two blades 1 are bent upward. By bending the front ends of the blades 1 upward, the obstruction of the surgical field by the hand holding the handle 3 can be reduced when cutting with the blade ends.

[0024] Furthermore, such as Figure 3As shown, the handle 3 includes a connecting section 31, a transition section 32, and a handle ring connecting section 33. The front end of the connecting section 31 is connected to the rear end of the blade 1. The transition section 32 is roughly Z-shaped. The front end of the transition section 32 is connected to the rear end of the connecting section 31, and the rear end of the transition section 32 is connected to the front end of the handle ring connecting section 33. The height of the handle ring connecting section 33 is lower than the height of the connecting section 31. The handle ring connecting section 33 is parallel to the connecting section 31. The handle ring 4 is connected to the handle ring connecting section 33. Because the height of the handle ring connecting section 33 is lower than the height of the connecting section 31 and the blade 1, the obstruction of the surgical field by the hand holding the handle 3 when cutting with the end of the blade 1 during surgery can be further reduced.

[0025] Furthermore, the connecting section 31 and the transition section 32 are round rod structures with the same outer diameter. The outer diameter of the handle ring connecting section 33 is smaller than that of the transition section 32. The inner wall of the handle ring connecting section 33 forms a planar notch 34. The handle ring 4 includes a handle ring body 41 and a connecting block 42. The connecting block 42 has a square structure, and the handle ring body 41 has a ring structure. Its inner end is connected to the outer end of the connecting block 42. The front wall of the connecting block 42 is provided with a sliding groove 43 that cooperates with the handle ring connecting section 33. The connecting block 42 is connected to the handle ring connecting section 33 through the connecting mechanism 5, ensuring that after the handle ring 4 is fitted onto the handle ring connecting section 33, when the surgical scissors are cutting, the inner ends of the two handle rings 4 are in contact, and the blade 1 can be closed to cut.

[0026] Furthermore, such as Figure 4 As shown, the distance between the inner wall of the groove 43 and the inner wall of the connecting block 42 is equal to the distance between the inner wall of the handle ring connecting section 33 and the inner wall of the transition section 32, ensuring that when the surgical scissors are cutting during surgery, the two blades 1 can fit together to cut when the inner walls of the two connecting blocks 42 come into contact.

[0027] Furthermore, such as Figure 5As shown, the connecting mechanism 5 includes a connecting plate 51, a connecting groove 52, a connecting bolt 53, a connecting hole 54, and a threaded hole 55. The connecting plate 51 is located in the middle of the outer side wall of the handle ring connecting section 33. The top of the connecting plate 51 is provided with a plurality of connecting holes 54 at equal intervals along its length. The middle of the outer side of the inner wall of the sliding groove 43 is provided with the connecting groove 52. The cross-sectional shape of the connecting groove 52 is the same as that of the connecting plate 51. The top two sides of the connecting plate 51 are provided with threaded holes 55. The threaded holes 55 communicate with the connecting groove 52. The external thread of the connecting bolt 53 matches and meshes with the internal thread of the threaded hole 55. The connecting hole 54 and the threaded hole 55 have the same diameter. When connecting, the connecting block 42 is first moved to a suitable position along the handle ring connecting section 33 and the connecting plate 51 through the sliding groove 43 and the connecting groove 52. Then, the connecting bolt 53 is screwed into the threaded hole 55 and then through the connecting hole 54 to complete the connection. The structure is simple and the installation and disassembly are relatively convenient.

[0028] like Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the spacing between the threaded holes 55 is 4 times the spacing between two adjacent connecting holes 54, so as to ensure that the connecting bolt 53 can pass through the connecting hole 54 after being screwed into the threaded hole 55, thereby completing the connection between the shank ring 4 and the shank ring connecting section 33.
