Claim 10:
11. A medical apparatus comprising:
an endoscope extending along a longitudinal axis and comprising:
a deflection control lever extending external to an outermost surface of the endoscope at a location adjacent to a proximal end of the endoscope for engagement by a user, the deflection control lever operably coupled to an actuator disposed internally within the endoscope and configured to control deflection of a distal end of the endoscope away from the longitudinal axis;
a control housing including a connector for removably attaching the control housing to the endoscope, the connector defining an inner surface sized and shaped to mate with an outer surface of the deflection control lever and comprising a portion which is deflectable and configured to resiliently snap onto the deflection control lever at the proximal end of the endoscope such that movement of the control housing causes a corresponding movement of the deflection control lever to control deflection of the distal end of the endoscope; and
a control actuation mechanism in the control housing, the control actuation mechanism comprising a joystick configured to actuate a retrieval device to capture biological material,
where the control actuation mechanism is configured to longitudinally slide a second member of the retrieval device relative to a first member of the retrieval device when the joystick is moved in a first direction, where the control actuation mechanism is configured to move the first member of the retrieval device when the joystick is moved in a second direction orthogonal to the first direction, where the second member extends through the first member, where the first member is a sheath and the second member comprises a basket, and where the control housing and the control actuation mechanism are configured to allow for deflection of the distal end of the endoscope, movement of the basket relative to the sheath, and movement of the sheath with a single finger of a user.
