Abstract
A surgical instrument has first and second components that can rotate relative to one another and a locking mechanism to selectively restrict or allow rotation between the first and second components. One component has a first array of two or more grooves or teeth spaced apart at a first angular pitch and at least one further groove or further tooth which does not correspond to the first angular pitch. The other component comprises a first tooth or a first groove to engage one of the first array of grooves or teeth to selectively restrict rotation to two or more predetermined rotational positions; the other component also selectively engages the at least one further groove or further tooth on the first component to selectively restrict rotation between the first and second components at a 0° rotational position.
