[0017] The embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0018] Embodiment 1

[0019] like Figures 1 to 3 As shown, the suture needle clamping device comprises: a base 1, a clamping body 2, an upper micrometer dynamometer 3, a lower micrometer dynamometer 4, a clamp module 5, a support 6, a connecting rod 7 and a lower limit screw 8. Among them, the upper surface of the clamping body 2 is provided with an upper micrometer fixing bracket 21 and a lower micrometer fixing bracket 22, and the clamping module 5 comprises a mold fixing block 51, an upper mold 52 and a lower mold 53.

[0020] The upper micrometer dynamometer 3 is fixed by the upper micrometer fixing bracket 21 and is located at the outer end of the upper mold 52, and the lower micrometer dynamometer 4 is fixed by the lower micrometer fixing bracket 22 and is located at the outer end of the lower mold 53. The upper mold 52 and the lower mold 53 are relatively mounted on the mold fixing block 51, and the adjacent ends of the upper mold 52 and the lower mold 53 are provided with grooves for the suture needle 100 to pass through. The upper micrometer dynamometer 3 is mounted on the outer end of the upper mold 52, and the lower micrometer dynamometer 4 is mounted on the outer end of the lower mold 53. The upper micrometer dynamometer 3 and the lower micrometer dynamometer 4 are used as micrometer regulators to control the external forces applied to the upper module 52 and the lower module 53 in the fixture module 5.

[0021] The device realizes the detachable connection between the clamp body 2 and the base 1, and the detachable connection between the mold fixing block 51 and the clamp body 2 by setting a plurality of hexagon socket nuts and threaded holes. Specifically, a mounting plate with an inclined structure is provided on the top of the base 1, and a mounting groove matching the shape of the mounting plate with the inclined structure is provided on the bottom of the clamp body 2. First threaded holes with opposite positions are provided on the side walls of the mounting plate and the mounting groove. A plurality of second threaded holes are provided on the mold fixing block 51. The hexagon socket nuts are adapted to the sizes of the first threaded holes and the second threaded holes. The clamp body 2 is tiltedly arranged on the base 1, and its lower surface is connected to the top end of the connecting rod 7. A lower limit screw 8 is provided at the bottom of the connecting rod 7 to make the clamp body 2 more stable.

[0022] Before using the device, select matching molds for installation according to the specifications of the suture needle 100 and the suture thread 200, and place the suture needle and the suture thread accurately into the groove of the needle clamping machine mold module. The operator operates the micrometer adjuster to stably clamp the suture needle, and then manually inserts the suture thread into the suture needle. The operator applies appropriate pressure to make the suture needle and the suture thread tightly combined, thereby completing the needle and thread connection.

[0023] The device of the utility model adopts a purely mechanical structure design, and is equipped with auxiliary components such as a micrometer adjuster and a connecting rod to ensure the stability and accuracy of the clamping process. This design performs well in the control of force and the adjustment of the mold, ensuring the accuracy and stability of the operation.
