A medical device may comprise a handle, including a main body and an actuator. The main body may include a first portion and a second portion. The main body may have an open configuration and a closed configuration. The actuator may include a first portion and a second portion. The actuator may have an open configuration and a closed configuration. The actuator may translate relative to the main body in the closed configurations of the main body and the actuator.

An ophthalmic surgery instrument, an add-on module, methods of assembling and de-assembling an ophthalmic surgery instrument The invention relates to an ophthalmic surgery instrument, comprising a handling unit (2), a surgical module (3) provided on the handling unit, and a shaft (4) at least partially surrounding the surgical module, wherein the surgical module and the shaft are mutually movable relative. The handling unit further comprises a guiding element (5) arranged at a distal end of the handling unit. The handling unit comprises a driving unit (8) for driving the surgical module or the shaft relative to the guiding element back and forth through the central bore of the guiding element, and an actuation unit (9) associated with the driving unit for actuating the driving unit upon manual actuation of the actuation unit, wherein the actuation unit includes a distal slider (10) at least partially surrounding the guiding element.

A pituitary rongeur medical instrument has jaws that can controllably articulate radially along a 90 arc in a single radial direction from a longitudinal axis of a shaft assembly of the pituitary rongeur and beyond a perimeter of a cannula during use. The pituitary rongeur has a handle, a shaft assembly defining a proximal end extending from the handle, and a distal end, with the jaws pivotally connected to the distal end for limited articulating radial movement of the jaws relative to the longitudinal axis of the shaft assembly, a jaw controller associated with the shaft assembly and configured to controllably close and open the jaws, and an articulation controller associated with the shaft assembly and configured to controllably articulate the jaws. The handle has a handgrip portion configured to receive a palm of a user and a lever portion with a finger loop for receiving fingers of the user.

A medical device that includes a handle, a shaft extending distally from the handle, an end effector extending distally from the shaft, a first actuator movably coupled to the handle, and a second actuator movably coupled to the handle. The first actuator is configured to (1) articulate the shaft in response to translating the first actuator in a first direction relative to the handle and the second actuator, and (2) actuate the end effector in response to translating the first actuator in a second direction relative to the handle and the second actuator. The second actuator is configured to (1) articulate the shaft in response to translating the second actuator in the first direction relative to the handle and the first actuator, and (2) actuate the end effector in response to translating the second actuator in the second direction relative to the handle and the first actuator.

An instrument driver comprises a base and a jaw assembly coupled to the base. The jaw assembly includes a first jaw having a gripping surface and a second jaw having a gripping surface. The instrument driver further comprises a driver assembly operably coupled to the jaw assembly to advance an elongated member relative to the base by translating the first and second jaws toward each other, thereby closing the jaw assembly and gripping the member between the respective gripping surfaces of the first and second jaws, translating the jaw assembly in a first axial direction when the jaw assembly is closed, translating the first and second jaws away from each other, thereby opening the jaw assembly and releasing the member from between the respective gripping surfaces of the first and second jaws, and translating the jaw assembly in a second axial direction when the jaw assembly is opened.

A medical device may include a handle having an actuator. A medical device may include a shaft. A medical device may include an end effector at a distal end of the medical device, wherein the actuator is configured to (1) articulate the shaft in response to moving the actuator in a first direction relative to a body of the handle and (2) actuate the end effector in response to moving the actuator in a second direction relative to the body of the handle.
