Abstract
A medical retrieval device used to remove objects such as urinary and biliary calculi from the body comprising a handle assembly with an independent rotational means, a sheath, and an object entrapping assembly. In preferred embodiments, the handle assembly comprises a longitudinally stationary base portion with a handle base and a rotating means and a thumb slide actuation means located between the distal and proximal ends of the handle base portion. Actuation of the thumb slide relative to the handle base causes the object entrapping assembly to be actuated between the open and closed positions. Rotation of the rotating means relative to the handle base causes precise rotation of the object entrapping assembly. The thumb slide actuation means and rotating means are separate and independent of each other, preventing inadvertent adjustment of the degree of actuation during rotation and preventing inadvertent adjustment of rotational position during actuation.
