Description

Technical Field

[0001] The utility model relates to the technical field of medical suture production, in particular to a suture needle device. Background Art

[0002] Suture is a sterile thread used for wound suturing, tissue ligation and tissue fixation. According to the absorbency of the suture, it can be divided into silk thread, catgut, chemical synthetic thread and pure natural collagen suture. The suture is threaded on the suture needle, and the suture needle is used to pierce the skin or tissue, and the suture is guided to suture the wound to ensure rapid healing of the wound. The commonly used suture needle has a very small lead hole, and the suture is very thin. In order to save time, a suture needle device is needed to quickly thread the suture needle.

[0003] In the Chinese patent with the announcement number CN213588376U, a novel suture thread needle device is disclosed. By setting the left baffle and the right baffle, the suture needle can be conveniently installed on the sealing pad and the suture needle can be pressed and fixed. By setting the guide tube, the exhaust fan and the exhaust tube, the suture thread is accurately extended to the top of the suture needle along the guide tube. Under the action of the exhaust fan, the suture thread is passed into the lead hole of the suture needle with the airflow, which is convenient and fast, thereby achieving the effect of improving work efficiency; however, the existing suture needles are generally arranged in an arc shape and of different sizes. When the suture needles are fixed by the sealing block, the needle hole positions of suture needles of different sizes are different. Therefore, it is difficult for the existing suture thread needle device to quickly thread suture needles of different sizes, so it is difficult to meet the needle-threading requirements of the suture thread. Therefore, we propose a suture thread needle device. Utility Model Content

[0027] As can be seen from the above, when in use, the suture needle 5 is placed between the two clamping blocks 6 and clamped, and then the suture thread is placed inside the wire-releasing tube 4. Under the action of the exhaust fan 2, the air in the vacuum cylinder 3 is sucked, and at the same time, the suture thread inside the wire-releasing tube 4 passes through the threading hole of the suture needle 5 and enters the interior of the vacuum cylinder 3 to complete the threading.

[0028] refer to Figure 1-Figure 4 As shown, an adjusting device 7 is arranged in the groove, and the adjusting device 7 includes a movable plate 708 arranged at the bottom of the groove, and a liftable adjusting block 701 is arranged above the movable plate 708. The middle part of the adjusting block 701 is recessed inward to form a cavity, and two clamping blocks 6 are arranged in the cavity. A transmission mechanism is arranged between the adjusting block 701 and the movable plate 708.

[0029] The transmission mechanism includes a threaded rod 703 rotatably mounted on the moving plate 708 and two limit rods 702 symmetrically fixed on the moving plate 708. A threaded hole matching the threaded rod 703 is provided at the bottom of the adjustment block 701. The threaded rod 703 is screwed into the threaded hole. The adjustment block 701 is slidably mounted on the upper half of the two limit rods 702. Two springs 704 are symmetrically arranged on the inner wall of the cavity. Limit holes matching the limit rods 702 are provided on both sides of the adjustment block 701. The free ends of the two springs 704 are connected to the two clamps. The opposite side of the block 6 is fixed; a rotating rod 707 is arranged inside the groove, a gear 706 is fixed in the middle of the rotating rod 707, and a rack 705 meshing with the gear 706 is arranged at one end of the movable plate 708; the top of the threaded rod 703 passes through the threaded hole and is fixed with a knob, and the outer wall of the knob is provided with convex patterns, which facilitate people to adjust the knob; a baffle is arranged on the top of the rotating rod 707, and chamfers are arranged on the sides facing each other of the two clamping blocks 6, and the friction of the two clamping blocks 6 on the suture needle 5 is increased by the chamfers.

[0030] By adopting the above technical solution:

[0031] When in use, the knob is rotated, and the knob drives the threaded rod 703 to rotate, and the threaded rod 703 cooperates with the threaded hole of the adjusting block 701. At the same time, the limiting rod 702 limits the adjusting block 701, so that the adjusting block 701 moves vertically up and down along the outer wall of the threaded rod 703, so that the adjusting block 701 drives the clamping block 6 to move vertically up and down through the spring 704, so that the clamping block 6 drives the suture needle 5 to move vertically up and down, so that the threading hole of the suture needle 5 moves to the same level as the wire release tube 4, and then Rotate the rotating rod 707, the rotating rod 707 drives the gear 706 to rotate, and the gear 706 drives the rack 705 meshing with it to move horizontally, so that the rack 705 drives the movable plate 708 to move, and the movable plate 708 drives the adjusting block 701 to move through the limiting rod 702, and the adjusting block 701 drives the clamping block 6 to move through the spring 704, so that the clamping block 6 drives the threading hole of the suture needle 5 to move to the outlet of the wire release tube 4, so that suture needles 5 of different sizes can be threaded.

[0032] In addition, refer to Figure 3 and Figure 4 As shown, a slider is fixed at the bottom of the movable plate 708, and a slide groove matched with the slider is provided at the bottom of the groove, and the movable plate 708 is limited by the cooperation between the slider and the slide groove.

[0033] By adopting the above technical solution:

[0034] When the movable plate 708 moves laterally, the movable plate 708 drives the slider to move, so that the slider moves along the inside of the slide groove, and the slide groove limits the movable plate 708 through the slider, so that the movable plate 708 can move laterally, thereby facilitating the device to accurately position the suture needle 5.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
