TISSUE THICKNESS MEASURING DEVICE

A tissue thickness measuring device includes an elongate member defining a first lumen therethrough, an inner shaft slidably received in the first lumen, a tool assembly, and an actuation rod dimensioned to be received through the inner shaft. In particular, the tool assembly includes a neck portion and first and second jaw members. The neck portion is operatively supported on the inner shaft such that the tool assembly is transitionable between a retracted state and an extended state. The first jaw member is fixedly secured with the neck portion. The second jaw member is movable relative to the first jaw member between an approximated position and a spaced apart position. The actuation rod is configured to be selectively coupled with the second jaw member. Rotation of the actuation rod transitions the second jaw member between the approximated and spaced apart positions.
