[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0024] like Figure 1 , Figure 2 as well as Figure 3 A medical surgical forceps shown includes an operating body, a forceps rod assembly and a pull rod assembly. The operating body includes a connecting seat 11 and two operating handles 12. The two operating handles 12 are rotatably installed at one end of the connecting seat 11, and the two operating handles 12 can be rotated toward or away from each other to open and close the operating handles 12.

[0025] Specifically, the clamp rod assembly includes a clamp rod 21, a fixed clamp mouth 23 and a movable clamp mouth 22. One end of the clamp rod 21 is formed as a connection end, and the other end of the clamp rod 21 forms an operating end. The connection end is installed on the connecting seat 11, and the connection end of the clamp rod 21 can be installed at the end of the connecting seat 11 away from the operating handle 12. In addition, a through-connection cavity is provided in the clamp rod 21, and the through-connection cavity runs through the operating end to the connecting end, and the fixed clamp mouth 23 is fixed to the operating end, and the movable clamp mouth 22 is rotatably connected to the operating end through a rotating shaft, and the movable clamp mouth 22 can be rotated close to or away from the fixed clamp mouth 23, so that the movable clamp mouth 22 and the fixed clamp mouth 23 can be opened and closed to achieve tissue clamping and release.

[0026] The pull rod assembly includes a pull rod 24, two connecting rods 25 and a locking member. The pull rod 24 is movably connected in the connecting cavity and can move along the axial direction of the connecting cavity. One end of the pull rod 24 extends from one end of the connecting cavity and is connected to the rotating shaft; the other end of the pull rod 24 extends from the other end of the connecting cavity and forms a linkage end. One end of the two connecting rods 25 is respectively hinged to the two operating handles 12, and the other ends of the two connecting rods 25 are hinged to the linkage end; the locking member can lock the two operating handles 12 to prevent the operating handles 12 from rotating.

[0027] On the basis of the above structure, when the medical surgical forceps of the utility model are used, during the operation, when it is necessary to clamp the diseased tissue removed during the operation, the two operating handles 12 of the operating body can be manually grasped, and the two operating handles 12 can be close to each other when subjected to force. Since the two operating handles 12 are hinged to the two connecting rods 25, after the two operating handles 12 are close to each other, the two connecting rods 25 can be linked to each other. In this way, when the two connecting rods 25 are close to each other, the linkage end of the pull rod 24 can be pushed toward the end of the connecting seat 11 close to the operating handle 12, so that the other end of the pull rod 24 can be linked to move in the direction of retracting into the connection cavity, thereby driving the movable jaw 22 to rotate close to the fixed jaw 23 to complete the clamping action.

[0028] When the clamping action is completed, the two operating handles 12 can be locked by the locking piece. In this way, the operating handles 12 can maintain a relatively fixed rotation after the clamping is completed, and the connecting rod 25 and the pull rod 24 will not loosen under the action of external force. The clamping state of the movable jaws 22 and the fixed jaws 23 is stable.

[0029] On the contrary, when releasing, the above-mentioned locking piece is unlocked, so that the two operating handles 12 rotate away from each other. After the two operating handles 12 are opened, the two connecting rods 25 can be pulled to expand each other, thereby pushing the linkage end toward the direction of the connecting cavity, thereby pushing the movable pliers mouth 22 at the other end of the pull rod 24 to open, completing the lowering action.

[0030] Compared with the prior art which directly adjusts by opening and closing the operating handle 12, in the present application, two operating handles 12 are linked with two connecting rods 25 to realize the push-pull action of the pull rod 24 inside the clamp rod 21, thereby driving the opening and closing of the movable clamp mouth 22 and the fixed clamp mouth 23 to complete the clamping and lowering, so that the opening and closing angle adjustment is more flexible.

[0031] Furthermore, in this embodiment, a connecting sleeve 241 may be provided on the outer surface of the connecting end, and connecting ears 2411 are provided on both sides of the connecting sleeve 241, and the connecting rod 25 is hinged to the connecting ears 2411 through a hinge axis. A perforation may be provided on the connecting ear 2411, and a through hole may be provided on the connecting rod 25 correspondingly. During assembly, the through hole of the connecting rod 25 corresponds to the perforation of the connecting ear 2411, and then a screw or other structure is inserted to perform hinged connection. In this way, there is no need to process a hole-shaped structure on the pull rod 24, and the connecting sleeve 241 is directly assembled before the connecting rod 25 and the connecting ear 2411 are hinged, which is convenient for assembly. In addition, the assembly surface formed by assembling the connecting ear 2411 and the connecting rod 25 is larger, and the structure is stable.

[0032] Furthermore, in order to facilitate the assembly of the connecting sleeve 241 and prevent the connecting sleeve 241 from axially moving relative to the pull rod 24 after assembly, a first annular groove is provided at the linkage end, and the connecting sleeve 241 can be sleeved in the first annular groove. After the connecting sleeve 241 is assembled into the first annular groove, the two ends of the connecting sleeve 241 can respectively abut against the two end walls of the first annular groove to prevent the connecting sleeve 241 from axial displacement, and the linkage structure is stable.

[0033] Furthermore, the locking member includes a first locking arm 26 and a second locking arm 27, wherein the first locking arm 26 is connected to one of the operating handles 12, and the second locking arm 27 is connected to the other operating handle 12. Specifically, a locking tooth 261 is provided on the first locking arm 26, and a plurality of locking tooth grooves 271 are provided on the second locking arm 27, so that after the two operating handles 12 are rotated close to each other, the clamping action of the movable jaw 22 and the fixed jaw 23 is completed, and the locking tooth 261 on the first locking arm 26 can be snapped into one of the corresponding locking tooth grooves 271 on the second locking arm 27.

[0034] Furthermore, the above-mentioned first locking arm 26 is hinged to the operating handle 12, and the locking member also includes a limit rod 29 and a limit buckle 28. A limit groove 123 is provided on the operating handle 12, and the limit buckle 28 is hinged to the limit groove 123. Specifically, one end of the limit buckle 28 is provided with a buckle body, and the other end of the limit buckle 28 is provided with a connecting arm, and the middle part of the limit buckle 28 can be hinged in the limit groove 123. One end of the above-mentioned limit rod 29 is hinged to the connecting arm of the limit buckle 28, and the other end of the limit rod 29 is hinged to the middle end of the first locking arm 26. In this way, when the limit buckle 28 rotates, the limit rod 29 can drive the first locking arm 26 to rotate in linkage when the limit buckle 28 rotates. When the specific operating handle 12 does not need to be locked, the buckle body of the limit buckle 28 can be separated from the limit groove 123, and the limit buckle 28 rotates upward to pull the other end connecting arm to rotate upward, thereby driving the limit rod 29 connected thereto upward, driving the first locking arm 26 to rotate upward, and the locking tooth 261 disengages from the locking tooth groove 271.

[0035] When locking the operating handle 12, the limit buckle 28 is pushed to rotate downward, and then the linkage connecting arm is downward, pushing the first locking arm 26 to rotate downward close to the second locking arm 27, so that the locking tooth 261 is engaged with the locking tooth groove 271, and thereafter the buckle body of the limit buckle 28 can be engaged in the limit groove 123 to maintain a relatively stable locking structure.

[0036] Furthermore, a storage groove 121 can be provided on the inner side of the operating handle 12, and the first locking arm 26 and the second locking arm 27 are both hinged to the storage groove 121. When not in use, the first locking arm 26 and the second locking arm 27 can be rotated to the storage groove 121 for storage, thereby facilitating the overall storage of the surgical forceps.

[0037] Furthermore, the outer surface of the operating handle 12 is provided with a plurality of second annular grooves 122, and the plurality of second annular grooves 122 are spaced apart in the extension direction of the operating handle 12. The plurality of second annular grooves 122 can form an uneven structure on the outer surface of the operating handle 12, thereby increasing the surface friction of the operating handle 12 and reducing the occurrence of slipping when a person holds the operating handle 12 by hand.

[0038] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the utility model.
