摘　　要：针对电手术器械会导致手术创口组织热损伤,而冷冻手术刀又会使创口组织坏死,不利于创口愈合及后续妊娠孕育等问题,本文设计了一款腹腔镜手术低温冷刀装置。该装置的设计方案是在传统手术刀的基础上增加安全护套,涉及定位冷刀导入、伸缩、防转、导向、氮气输入、积液回收等技术。该装置的手术刀片可以在更换、工作、安全3种状态下进行定位,使低温冷刀进出腹腔安全可靠;其氮气低温可以加速微血管冷凝,减少创口出血量,保证手术创口组织新鲜,有利于术后创口愈合及后续妊娠,并能够兼容腹腔积液的有效清理,使腹腔镜手术过程更加完善。The electrosurgical instrument might cause the thermal damage of the surgical wound tissue, whereas the cryo-surgical system would result in necrosis of the wound tissue, both of which were harmful to wound healing and subsequent pregnancy. In view the problems, a low-temperature cryo-scalpel was designed for laparoscopic surgeries in this paper, which added the security sheath to the traditional surgical system. The system was integrated with multiple technologies, including positioning and introduction, expansion, anti-rotation, guidance, nitrogen input as well as accumulated fluid collection of the cryo-scalpel. Positioning of the surgical blade of the device could be performed under three statuses： replacement, work and safety, making it safe and reliable to enter and exit from the abdominal cavity. The nitrogen could promote the capillary condensation, reduce the wound bleeding, and ensure the freshness of the surgical wound tissue, which was conducive to the postoperative wound healing and subsequent pregnancy. Additionally, the device could also make the accumulated fluid in the abdominal cavity cleaned effectively so as to perfect the process of laparoscopic surgeries.
