Abstract:
A curved spatula made from a pseudoelastic nickel-titanium alloy (Tinel) has been developed and evaluated in animal experiments prior to its use in humans. Its adjustable, curved functional end enables laparoscopic dissection around structures such as arteries, ducts, the oesophagus and the colon. The initial experience with this pseudoelastic instrument has been entirely favourable and indicates the need for the development of a new generation of laparoscopic instruments based on shape-memory alloys.
