腹腔镜手术就是利用腹腔镜及其相关器械对腹部疾病进行的手术。为使腹腔镜手术拥有足够空间操作，需持续灌注腹腔予二氧化碳气体建立人工气腹，人工气腹是腹腔镜手术必要的条件。Laparoscopic surgery is the use of laparoscopy and related instruments for abdominal diseases. In order to have enough space for laparoscopic surgery, it is necessary to continuously perfuse the abdominal cavity with carbon dioxide gas to establish artificial pneumoperitoneum. Artificial pneumoperitoneum is a necessary condition for laparoscopic surgery.
然而，现有的设备只能将气体灌注到腹腔中，而在腹腔镜手术操作中，在对深部腹腔脏器、组织脏器的侧面或背面进行解剖时，或者有炎症的脏器与周围组织之间存在紧密粘连需要分离时，或者解剖的脏器被重要的血管和神经等组织包绕时，现有的腹腔镜常规器械在进行解剖操作时往往较为困难，而单纯的对组织电切可能会造成意外的出血，电灼伤或者造成重要脏器的副损伤。CN201811309408.1公开了一种腹腔镜手术用高频电刀，包括虽然具有电切或者喷气功能，但是结构复杂，不利于深入到腹部脏器间进行操作。However, existing devices can only infuse gas into the abdominal cavity, and in laparoscopic procedures, when dissecting deep abdominal organs, the lateral or back of tissue organs, or inflamed organs and surrounding tissue When there are tight adhesions between them that need to be separated, or when the dissected organs are surrounded by important blood vessels and nerves and other tissues, the existing laparoscopic conventional instruments are often difficult to perform dissection operations, and simple tissue electrocution may be possible. It can cause accidental bleeding, electrical burns or secondary damage to vital organs. CN201811309408.1 discloses a high-frequency electrosurgical knife for laparoscopic surgery. Although it has the function of electric cutting or air jet, the structure is complicated, which is not conducive to going deep into the abdominal organs for operation.
