本实用新型涉及医疗手术用的辅助器材，具体涉及一种用于腹腔镜胃手术的肝脏牵开装置。The utility model relates to auxiliary equipment for medical operations, in particular to a liver retractor for laparoscopic gastric operations.
背景技术Background technique
腹腔镜胃手术因整体创伤小、恢复快，在国内外已逐步开展，但人类的胃位于肝脏侧后方，自贲门、胃体、幽门沿线，胃小弯一侧约50％的胃组织被肝脏覆盖、遮挡。传统开腹进行胃手术时，必须由助手用专门的拉钩将肝脏持续牵拉，以充分暴露胃小弯，才能完成手术。但在腹腔镜下做胃手术时，肝脏拉钩无法进入腹腔，胃小弯侧的暴露是将钳子或可收缩的挡板从腹壁戳孔送入腹腔，由助手持续挑起肝脏，达到暴露胃手术视野的目的。但是，这种暴露方法存在明显缺陷：①钳子或挡板容易损伤肝脏；②助手必须持续占用一个戳孔来挑肝脏，腾不出手来，不能有效地配合术者进行手术操作；③受腹壁戳孔尺寸限制，进入腹腔的钳子和挡板的大小、形状均不理想，达不到满意的暴露效果。目前，由于手术视野的暴露比较困难，特别是胃小弯侧的暴露迄今尚无理想的办法，严重制约了腹腔镜胃手术的推广普及。Laparoscopic gastric surgery has been gradually carried out at home and abroad due to the overall small trauma and quick recovery. However, the human stomach is located behind the liver. From the cardia, gastric body, and pylorus, about 50% of the gastric tissue on the side of the lesser curvature of the stomach is covered by the liver. cover, cover. In traditional laparotomy for gastric surgery, the liver must be continuously pulled by an assistant with a special retractor to fully expose the lesser curvature of the stomach before the operation can be completed. However, during laparoscopic gastric surgery, the liver retractor cannot enter the abdominal cavity. The exposure of the lesser curvature of the stomach is to poke a hole through the abdominal wall with forceps or a retractable baffle and send it into the abdominal cavity. The assistant continues to lift the liver to achieve gastric surgery. purpose of vision. However, there are obvious defects in this exposure method: ① forceps or baffles are easy to damage the liver; ② assistants must continue to occupy a poking hole to pick the liver, and cannot free up their hands to effectively cooperate with the surgeon in the operation; ③ the abdominal wall is poked The size of the hole is limited, and the size and shape of the forceps and baffles entering the abdominal cavity are not ideal, and the satisfactory exposure effect cannot be achieved. At present, due to the difficulty in exposing the surgical field of view, especially the exposure of the lesser curvature of the stomach, there is no ideal way so far, which seriously restricts the popularization of laparoscopic gastric surgery.
此外，在腹腔镜下通过戳孔完成胃部肿瘤切除后，再开切口取出标本，并利用该切口完成消化道重建，称为腹腔镜辅助下胃切除术，是目前国内外普遍采用的方式，也存在一些亟待解决的问题，即如何简便地完成腹腔镜下消化道重建的问题。以腹腔镜胃癌根治术为例，腹腔镜下消化道重建，尤其是近端胃切除和全胃切除后的消化道重建存在很大困难。由于手术器械只能通过腹壁上几个直径0.5cm或1cm的小孔进入，必须使用腹腔镜手术专用器械，开腹手术使用的成熟简便的器械完全用不上，由此导致手术难度增加，手术时间延长，安全性降低，手术器械费用大幅度上升，腹壁切口延长，这严重制约了腹腔镜胃肠手术的普遍开展。在腹腔镜胃癌手术中切除的标本必须通过腹壁切口取出，通常是上腹正中切口，视肿瘤大小，切口约3～5cm长；腹腔镜下远端胃切除术基本不用再扩大切口，就能完成胃肠吻合，但是，腹腔镜下近端胃切除和全胃切除后的消化道重建比较复杂，要借助开腹手术的管状吻合器等体积较大的器械，因此切口必须相应延长至8～10cm才能完成。即使如此，8～10cm的切口也还嫌小，手术视野暴露不佳，手术难度仍然比较大。再者，腹壁开口后若要再建立约为12mm汞柱压力(0.09Pa)的气腹继续进行手术操作，除非将切口临时缝合，因此一台手术往往要将切口反复拆开、缝合几次才能最终完成，导致整个手术时间及患者的麻醉时间延长，对切口部位的损伤也增大。In addition, after gastric tumor resection is completed by poking a hole under laparoscopy, an incision is made to take out the specimen, and the incision is used to complete the reconstruction of the digestive tract, which is called laparoscopic-assisted gastrectomy, which is currently a commonly used method at home and abroad. There are also some urgent problems to be solved, that is, how to easily complete the reconstruction of the digestive tract under laparoscopy. Taking laparoscopic radical gastrectomy as an example, laparoscopic digestive tract reconstruction, especially after proximal gastrectomy and total gastrectomy, is very difficult. Since surgical instruments can only enter through a few small holes with a diameter of 0.5 cm or 1 cm on the abdominal wall, special instruments for laparoscopic surgery must be used. Prolonged time, reduced safety, a substantial increase in the cost of surgical instruments, prolonged abdominal incision, which seriously restricts the widespread development of laparoscopic gastrointestinal surgery. The resected specimen in laparoscopic gastric cancer surgery must be taken out through an incision on the abdominal wall, usually a midline incision on the upper abdomen. Depending on the size of the tumor, the incision is about 3 to 5 cm long; laparoscopic distal gastrectomy can be completed basically without enlarging the incision Gastrointestinal anastomosis, however, the reconstruction of the digestive tract after laparoscopic proximal gastrectomy and total gastrectomy is relatively complicated, and large-volume instruments such as tubular staplers for laparotomy must be used, so the incision must be extended to 8-10 cm accordingly to complete. Even so, the incision of 8-10 cm is still too small, the surgical field of view is not well exposed, and the operation is still relatively difficult. Furthermore, if the pneumoperitoneum with a pressure of about 12 mm Hg (0.09 Pa) is to be established after the opening of the abdominal wall to continue the operation, unless the incision is temporarily sutured. Finally, the whole operation time and the patient's anesthesia time are prolonged, and the damage to the incision site is also increased.
