Description

Technical Field

[0001] The invention relates to the technical field of suturing devices, and in particular to a suturing device for emergency wound care. Background Art

[0002] With the continuous development of medical technology, wound treatment and care have become an important part of clinical treatment. Wound suturing technology, as a common wound repair method, has been widely used in the treatment of various acute and chronic wounds. Although traditional wound suturing methods have achieved significant therapeutic effects, they still have certain shortcomings in emergency situations or in the treatment of wounds in certain specific parts (such as arms, legs, etc.). Current suturing technology is mostly based on traditional manual suturing methods, and doctors use surgical suture needles and threads to suture one stitch at a time.

[0003] The arm is one of the parts of the human body that moves more frequently, and due to the special structure of the arm muscles and skin, the closing and fixation of the wound edges are particularly complicated. Although the existing suturing devices can be effectively used in some common parts, they lack specific designs for parts such as the arm that are highly mobile and have irregular shapes, resulting in the inability to fully solve the problems of supporting the patient's arm and pre-closing the wound skin. Since arm wounds are often accompanied by intense activities and a high range of motion, if the existing suturing devices cannot provide sufficient support and stability, difficulties will arise during the suturing process, which may lead to problems such as suture line breakage, wound infection, and poor healing. In addition, due to the insufficient design of the suturing device, it is impossible to effectively pre-close the wound skin in the early stages, which may prolong the operation time, increase the patient's pain, and even affect the later recovery process. For this reason, it is necessary to improve the devices under the existing technology. Summary of the invention
