1. A medical device, comprising:
an operating member that includes an actuation portion;
a hub that includes a channel receiving the actuation portion of the operating member, wherein the actuation portion of the operating member is movable within the channel; and
an end effector, wherein the end effector is movable between a closed configuration and an open configuration,
wherein the operating member is extendable distally to transition the end effector to the open configuration and extend the actuation portion,
wherein the operating member is retractable proximally to transition the end effector to the closed configuration and retract the actuation portion, and
wherein the medical device is formed through an additive manufacturing process,
wherein the end effector includes a first arm and a second arm, wherein each of the first arm and the second arm includes a control portion that extends within the hub to interact with the actuation portion, wherein the control portions of the first and second arms each includes an extension surface and a retraction surface offset from the extension surface, wherein the hub includes indentations and the control portions include extensions within the indentations, to pivotably hold the control portions within the hub, wherein a distal portion of the actuation portion includes two prongs offset from each other, wherein each prong includes an extension face, a retraction face, an angled face, and an opening, wherein distal extension of the actuation portion is configured to (i) cause the extension face of one prong to contact the extension surface of one of the first and second arms and (ii) transition the one of the first and second arms to the open configuration, and wherein proximal retraction of the actuation portion is configured to (i) cause the retraction face of the one prong to contact the retraction surface of the other one of the first and second arms and (ii) transition the other one of the first and second arms to the closed configuration.
