The needle threading consists of passing the string through the loops at different angles and heights. The small knots on the string create additional challenge, requiring the use both hands. The numbers on the pegboard suggest the order in which the string is to be passed through the loops. This exercise helps improve the coordination of both hands. The arrangement of pegs requires maneuvering laparoscopic instruments at different angles. The placement and angling of the loops was consulted and supervised by practicing surgeons.
