Abstract
A medical device that includes a handle, a shaft extending distally from the handle, an end effector extending distally from the shaft, and a first actuator coupled to the handle and secured to a first wire. The first wire extends through the shaft, and the first actuator is configured to pivot relative to the shaft to pull the first wire proximally and to deflect the end effector relative to the shaft.
Claims19
A medical device, comprising:
- a handle that includes a pair of pins positioned on opposing surfaces at a proximal end of the handle and extending radially inward relative to a longitudinal axis of the handle;
- a shaft extending distally from the handle;
- an end effector extending distally from the shaft;
- a first actuator coupled to the handle and secured to a first wire, wherein the first actuator includes:
- a housing that includes a first channel and a distal opening, wherein the first channel is configured to receive a proximal portion of the first wire extending distally from the housing and through the distal opening, and
- a distal extension that includes a pair of sidewalls, and a pair of pin openings formed in opposing surfaces of the pair of sidewalls;
- and
- a second actuator coupled to the handle and secured to a second wire, wherein the second actuator is received within a slot of the handle, wherein the second wire extends through the shaft and is coupled to the end effector,
- wherein the pair of pins of the handle and the pair of pin openings of the first actuator define a pivot point, such that the first actuator is pivotably coupled to the handle about the pivot point;
- wherein the first actuator is configured to deflect the end effector to a deflected configuration relative to the shaft in response to pivoting a proximal portion of the first channel towards a proximal direction about the pivot point, and the first actuator is configured to return the end effector to an undeflected configuration relative to the shaft in response to pivoting the proximal portion of the first channel towards a distal direction about the pivot point,
- wherein the second actuator is configured to translate relative to the slot of the handle to pull the second wire proximally to actuate the end effector.

A medical device, comprising:
- a handle;
- a shaft extending distally from the handle;
- an end effector at a distal end of the shaft;
- a first actuator including a housing that includes a first channel, and a distal opening aligned with the first channel, wherein the first channel is configured to receive a proximal portion of a first wire extending distally from the housing and through the distal opening, and wherein the first channel is formed on an outer surface of the housing such that a side of the first channel is open;
- and
- a second actuator including a second wire disposed within the shaft, wherein the second actuator is slidable relative to the handle;
- wherein the first actuator is configured to retract the first wire proximally relative to the shaft to deflect the end effector, and the first actuator is configured to deflect the end effector to a deflected configuration relative to the shaft in response to pivoting a proximal portion of the first channel towards a proximal direction about a pivot point, and the first actuator is configured to return the end effector to an undeflected configuration relative to the shaft in response to pivoting the proximal portion of the first channel towards a distal direction about the pivot point, wherein, in the undeflected configuration, the first channel is angled relative to a longitudinal axis of the handle;
- and
- wherein the second actuator is configured to retract the second wire proximally relative to the shaft to move the end effector from an open configuration to a closed configuration.

A medical device, comprising:
- a handle including:
- a proximal extension that includes a pair of pins positioned on opposing surfaces of the proximal extension and extending radially inward relative to a longitudinal axis of the handle;
- and
- a slot extending along the longitudinal axis and distal of the pair of pins;
- a shaft extending distally from the handle;
- an end effector coupled to a distal end of the shaft;
- a first actuator including:
- a housing that includes a first channel secured to a first wire extending distally from the housing through a distal opening aligned with the first channel;
- and
- a distal extension that includes a pair of sidewalls, and a pair of pin openings formed in opposing surfaces of the pair of sidewalls;
- and
- a second actuator disposed in the slot of the handle and secured to a second wire;
- wherein the first wire and the second wire respectively extend through the shaft and are respectively coupled to the end effector;
- wherein the pair of pins of the handle and the pair of pin openings of the first actuator define a pivot point, such that the first actuator is pivotably coupled to the handle about the pivot point proximal of the distal opening of the housing;
- wherein the pair of sidewalls of the first actuator at least partially define the distal opening aligned with the first channel of the housing at a distal end of the first actuator;
- wherein the first actuator is configured to deflect the end effector to a deflected configuration relative to the shaft in response to pivoting a proximal portion of the first channel towards a first direction about the pivot point, and the first actuator is configured to return the end effector to an undeflected configuration relative to the shaft in response to pivoting the proximal portion of first channel towards a second direction about the pivot point opposite the first direction.
