Abstract
Medical devices and related methods are discussed, including a medical device that includes a handle with a housing and an actuator mechanism disposed within the housing. The actuator mechanism may include a biasing member and a disk rotatable between a first position and a second position, e.g., the biasing member having a first length and exerting a first distal force on the disk in the first position, and having a second length different from the first length and exerting a second distal force on the disk less than the first distal force in the second position.
Claims20
A medical device comprising:
- a handle comprising a housing and an actuator mechanism disposed within the housing, wherein the actuator mechanism includes:
- a disk rotatable between a first position and a second position;
- and
- a biasing member, wherein a proximal end of the biasing member is coupled to the disk and a distal end of the biasing member is coupled to the housing,
- wherein, in the first position of the disk, the biasing member has a first length and exerts a first distal force on the disk;
- and
- wherein, in the second position of the disk, the biasing member has a second length different from the first length and exerts a second distal force on the disk less than the first distal force.
A medical device comprising:
- a handle comprising a housing and an actuator mechanism disposed within the housing, wherein the actuator mechanism includes:
- a rotatable disk;
- a biasing member coupled to, and configured to exert a force on, the disk;
- a first control member coupled to the disk;
- and
- a second control member coupled to the disk;
- wherein the handle is configured to rotate from a first configuration to a second configuration by rotation of the disk, and wherein, in the second configuration, the force exerted on the disk is greater than the force exerted on the disk in the first configuration.
A medical device comprising:
- a handle comprising a housing and an actuator mechanism disposed within the housing, wherein the actuator mechanism includes:
- a disk rotatable between a first position and a second position;
- a biasing member, wherein a proximal end of the biasing member is coupled to the disk and a distal end of the biasing member is coupled to an internal surface of the housing;
- a first control member coupled to the disk;
- and
- a second control member coupled to the disk;
- wherein the disk includes a first protrusion on a first side of the disk and a second protrusion on a second side of the disk, wherein the housing receives the first protrusion on a first side of the handle and the second protrusion on a second side of the handle opposite the first side.
