Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to a semi-automatic intraoral suture device. Background Technology

[0002] After intraoral surgery, suturing the wound is a crucial step that directly affects the patient's postoperative recovery. Currently, intraoral wound suturing is usually performed using a standard needle holder. The surgeon needs to hold the needle holder, clamp the curved suture needle, insert the needle from one side of the wound edge, pass it inside the wound, and then exit from the other side of the wound edge.

[0003] However, in actual operation, the limited mouth opening of patients brings great inconvenience to doctors. The small space inside the oral cavity, the different surgical sites, and the obstruction of vision by tissues such as teeth, tongue, and buccal mucosa, as well as the long suturing operation, force patients to keep their mouths open for a long time, which can lead to discomfort in the bilateral temporomandibular joints. Therefore, this utility model proposes a semi-automatic intraoral suture device to solve the above problems. Utility Model Content

[0004] In view of the defects of the existing technology, the purpose of this utility model is to provide a semi-automatic intraoral suture device.

[0005] To achieve the above objectives, this utility model provides a semi-automatic intraoral suture device, comprising a first rod, of which two are provided and are rotatably connected in a cross manner. A second rod is mounted on the bottom end of each of the two first rods via an angle adjustment mechanism. A needle threader is fixedly mounted on the bottom end of one of the second rods, and a needle holder is fixedly mounted on the bottom end of the other second rod. The end of the needle threader near the needle holder is open and has a hollow needle-like structure inside. A suture needle is detachably mounted inside the needle holder, and a suture thread is fixedly mounted on the tail end of the suture needle. The end of the needle threader has a needle hole for the suture needle to pass through. A scissor opening and closing mechanism is mounted on the top of the first rod, which drives the two first rods to open and close.

[0006] Furthermore, the needle holder is transparent, and a perforation is provided on the side wall of the needle holder. The suture passes through the perforation and extends outward. Both the needle inserter and the needle holder are arc-shaped.
