In an aspect, a medical device of the disclosed medical devices may comprise a tubular member defining a lumen, a threaded member extending through the lumen, and a handle including a threaded rod coupled to the threaded member, a fixed member with a threaded inner surface, and an actuator configured to translate the threaded rod distally. An interaction between the threaded rod and the threaded inner surface of the fixed member may be configured to rotate the threaded rod and the threaded member. ## Claims ### Claim 1 A medical device comprising: a tubular member defining a lumen; a threaded member extending through the lumen; and a handle including: a threaded rod coupled to the threaded member; a fixed member with a threaded inner surface; and an actuator configured to translate the threaded rod distally; wherein an interaction between the threaded rod and the threaded inner surface of the fixed member is configured to rotate the threaded rod and the threaded member. ### Claim 2 (depends on 1) The medical device of claim 1, comprising: a brush disposed at a distalmost end of the threaded member. ### Claim 3 (depends on 2) The medical device of claim 2, wherein the brush is configured to rotate with the threaded member. ### Claim 4 (depends on 1) The medical device of claim 1, wherein the threaded member has a proximal unthreaded portion. ### Claim 5 (depends on 1) The medical device of claim 1, wherein a distal end of the tubular member has a flared shape. ### Claim 6 (depends on 1) The medical device of claim 1, wherein the actuator is coupled to the threaded rod at a hinge, and an actuation of the actuator causes the threaded rod to translate distally. ### Claim 7 (depends on 6) The medical device of claim 6, wherein the hinge includes a bearing configured to allow for rotation of the threaded rod. ### Claim 8 (depends on 1) The medical device of claim 1, wherein the handle includes: a longitudinally extending shaft defining a handle lumen, wherein the threaded rod and the fixed member are disposed in the handle lumen. ### Claim 9 (depends on 8) The medical device of claim 8, wherein the handle includes: a grip extending substantially perpendicular to the longitudinally extending shaft; and an arm connecting the grip to the actuator. ### Claim 10 (depends on 1) The medical device of claim 1, wherein the handle includes: a resilient member configured to bias the threaded rod toward the actuator. ### Claim 11 (depends on 10) The medical device of claim 10, wherein the resilient member is a coil spring. ### Claim 12 (depends on 1) The medical device of claim 1, wherein the handle includes: a port configured to be coupled to a fluid source, the port in fluid communication with the lumen of the tubular member. ### Claim 13 (depends on 12) The medical device of claim 12, wherein the threaded member is configured to advance a fluid from the fluid source distally through the lumen of the tubular member. ### Claim 14 (depends on 1) The medical device of claim 1, wherein the threaded member includes a helical thread. ### Claim 15 (depends on 1) The medical device of claim 1, wherein rotation of the threaded member is configured to rotate a brush to collect a cytology sample. ### Claim 16 A medical device comprising: a tubular member defining a lumen; a threaded member extending through the lumen; and a handle including: a fluid port in fluid communication with the lumen; a rod coupled to the threaded member; and an actuator configured to translate the rod distally; wherein translation of the rod is configured to rotate the threaded member and to advance a fluid distally through the lumen of the tubular member. ### Claim 17 (depends on 16) The medical system of claim 16, wherein a distal end of the threaded member includes a brush, and a distal end of the tubular member has a flared shape. ### Claim 18 A medical device comprising: a tubular member defining a lumen; a threaded member extending through the lumen; a brush disposed at a distalmost end of the threaded member; and a handle including an actuator configured to rotate the threaded member so as to move a fluid distally through the lumen to the brush. ### Claim 19 (depends on 18) The medical device of claim 18, wherein the brush is configured to rotate with the threaded member. ### Claim 20 (depends on 18) The medical device of claim 18, wherein the threaded member has a proximal unthreaded portion.
