Abstract:
Surgery for rectal cancer has obtained quick improvement in techniques and concepts in recent years but still has challenging areas. Colorectal surgeons always seek to make operations clearer and easier, so that surgery can be safer and less time-consuming while guaranteeing surgical goals. With this purpose, our team have explored to make innovations in operations for rectal cancer and translate relevant patents from 2009. We summarize our achievements in this article as follows: (1) Reverse Miles operation (perineal operation first then laparoscopic abdominal operation) with two relevant patents—specialized instruments bag for laparoscopic operations (patent number ZL201520442331.0) and accessory spotlight for ultrasound scalpel (patent number ZL20102 0137689.X). (2) Laparoscopic sphincter-saving surgery for low rectal cancer through marker meeting approach with two patents—vacuum rectal drainage tube with functions of irrigation and ventilation (patent number ZL201520374385.8) and sterile sleeve cover of ultrasound scalpel handle (patent number ZL201920648102.2). (3) Laparoscopic radical resection of colorectal cancer and natural orifice specimen extraction. Different methods were designed according to the location of the tumor that classified as 20-40 cm, 10-20 cm and 5-10 cm to anus. Two relevant patents were specialized instruments for natural orifice specimen extraction (patent application number ZL2017101480141) and plastic film sleeve for natural orifice specimen extraction (patent application number ZL 201921169857.0). Reformation of surgical technique and innovation of surgical instruments should be conducted by surgeons with innovative thinking who always seek the way to translate ideas to patents and then real products to promote surgical treatment.
