背景技术Background technique

腹腔镜手术是一门新发展起来的微创方法，腹腔镜手术传统方法是插入一个叫做戳卡的管道状工作通道，以后一切操作均通过这个管道进行；再用特制的加长手术器械在视频监视下完成与开放手术同样的步骤，达到同样的手术效果。同时在手术过程中为了提升手术操作空间，还需要对一些组织需要进行提拉或者定位。通常采用腹腔镜手术进行腹腔或胸腔手术治疗时，一般需要先设置出1~5个直径为5~15mm贯穿腹（胸）壁全层的穿刺通道，使腹腔镜和手术器械能够从这些穿刺通道进入腹腔或胸腔实施手术，手术结束拔除"戳卡"和手术器械后，须对这些穿刺通道进行缝合，以便伤口痊愈。目前对腹腔或胸腔壁穿刺通道的缝合采用的缝合针均为弯曲的缝针，但穿刺孔相对较小，操作起来就十分困难，致使直径相对较小的穿刺通道往往不易缝合，有时会因为缝合不完善而发生术后出血、伤口愈合不良，或可诱发感染，甚至造成腹壁疝，给病人带来很大痛苦。Laparoscopic surgery is a newly developed minimally invasive method. The traditional method of laparoscopic surgery is to insert a tube-shaped working channel called poking card, and all operations will be performed through this channel; Complete the same steps as open surgery to achieve the same surgical effect. At the same time, in order to improve the operating space during the operation, some tissues need to be lifted or positioned. Usually, when laparoscopic surgery is used for abdominal or thoracic surgery, it is generally necessary to set up 1 to 5 puncture channels with a diameter of 5 to 15 mm through the entire abdominal (chest) wall, so that laparoscope and surgical instruments can pass through these puncture channels. Enter the abdominal cavity or thoracic cavity to perform surgery. After the operation is completed and the "poke card" and surgical instruments are removed, these puncture channels must be sutured to allow the wound to heal. At present, the suture needles used for suturing the puncture channels of the abdominal cavity or thoracic wall are all curved needles, but the puncture holes are relatively small, and it is very difficult to operate. If it is not perfect, postoperative bleeding and poor wound healing may occur, or it may induce infection, and even cause abdominal hernia, which brings great pain to the patient.
