A new type of anti-slip drainage tube that was supported by pancreatic duct was designed,which consisted of an inner tube and an outer tube,and the nested design was adopted for inner tube and outer tube. The outer wall of the outer tube was designed with an anti-slip piece. The expansion part of the inner tube head and the device of limiting location at the end of the outer tube can prevent complete separation of inner tube and outer tube when relative displacement occurred between inner tube and outer tube,and can ensure the sealing property of them. In the excision surgery of pancreas and duodenum,the new placed support tube of pancreatic duct can effectively prevent pancreatic fistula and stenosis of anastomotic site between pancreas and intestines,and significantly reduce the incidence of postoperative pancreatic fistula and other serious complications of surgery for pancreas and duodenum,which can help patients to recover quickly.
