Profile: Guangzhou T.K Medical Instrument Co., Ltd., is a supplier of disposable laparoscopic products, disposable medical devices, minimally invasive surgery products, embedded surgical devices, and artificial tissues & organs. Our products include specimen retrieval bag, trocars and veress needle/insufflation needle. Our veress needles are single-use insufflation needles for puncturing the abdominal cavity and supplying gas during laparoscopic surgery. They are available in 120 mm and 150 mm lengths. The stylet retracts as the needle is pushed through the abdominal wall, and automatically slides forward once the peritoneum has been penetrated. An audible click, and a visual abdominal free-space indicator verify the correct position in the abdominal cavity.
