1. A method of locking a steering mechanism of a medical device handle, the method comprising:
rotating a lock lever of a locking mechanism about an axis to move the lock lever to a locked position, causing a first cam profile of a first member of the locking mechanism to interact with a second cam profile of a second member of the locking mechanism, wherein the first member includes a boss portion configured to be keyed for rotation with a portion of the lock lever;
as a result of the interaction between the first cam profile and the second cam profile, translating the second member of the locking mechanism relative to a housing of the medical device handle, wherein the second member includes a boss section that is configured for receiving at least a portion of the first member therein; and
as a result of the translation of the second member, causing a first side of the steering mechanism to frictionally engage with the housing of the medical device handle;
wherein the steering mechanism comprises a first pulley, a second pulley, and a thrust plate rotationally fixed between the first pulley and the second pulley, wherein the translation of the second member causes a side of the first pulley to frictionally engage with a first side of a thrust plate, thereby restricting rotation of the first pulley, and wherein the translation of the second member causes a side of the second pulley to frictionally engage with a second side of a thrust plate.
