我科和上海手术器械六厂协作改进了南京的SWWH-3型食管胃吻合器。使用于食管癌和贲门癌切除术,有肯定可取的优点。和南京SWWH-3型吻合器相比,吻合器口径由1.5厘米增大为1.8厘米。头部为塑料贮钉槽及圆形切割刀,与联动动力轴杆不固定联结,每次用后均可调换,保证切割锋利。缝合钉采用双列轴向交错排列,内折缘环形缝合,使食管胃吻合器的接触面大,缝合牢固。 In collaboration with Shanghai Surgical Instruments No. 6 Plant, our department has improved the Nanjing SWWH-3 esophageal gastric stapler. Used in esophageal and cardiac cancer resection, there are definite desirable advantages. Compared with the Nanjing SWWH-3 stapler, the stapler diameter increased from 1.5 cm to 1.8 cm. The head is a plastic storage slot and a round cutter, and is not fixedly connected with the linkage power shaft. It can be exchanged after each use to ensure sharp cutting. The staples were staggered in a double-row axial arrangement, and the inner flange was sutured to make the contact surface of the esophageal-gastric stapler large.
