PHYSICIAN-CONTROLLED HANDLE FOR MEDICAL DEVICES
A medical device includes a handle that includes a first member and a second member. Outer and inner elongate members of the medical device project from a distal end of the first member. The first and second members move, such as rotationally or pivotably move, relative to each other to control relative longitudinal movement of the outer and inner elongate members.
1 . A handle for a medical device, the handle comprising:
a first member from which an inner elongate member and an outer elongate member extend; and
a second member configured to move toward and away from the first member,
wherein movement of the second member toward and away from the first member controls relative longitudinal movement of the inner and outer elongate members.
2 . The handle of claim 1 , wherein the movement of the second member toward and away from the first member comprises rotational movement.
3 . The handle of claim 1 , wherein the first member and the second member are connected to each other via a hinge about which the first member and the second member pivotably move relative to each other.
4 . The handle of claim 1 , wherein the second member comprises a bell crank comprising a pair of arms configured to move opposite from each other toward and away from the first member.
5 . The handle of claim 4 , wherein one of the pair of arms is configured to move toward and away from a proximal end of the first member.
6 . The handle of claim 5 , wherein the one of the arms is configured to translate movement toward and away from the proximal end of the first member to longitudinal movement of the inner elongate member.
7 . The handle of claim 4 , wherein one of the pair of arms is configured to move toward and away from an elongate side of the first member.
8 . The handle of claim 4 , wherein the bell crank further comprises an arm connection element connected to each of the pair of arms and circumferentially extending about a pivot point of the bell crank.
9 . The handle of claim 8 , wherein the arm connection element extends and is configured to move through the first member.
10 . The handle of claim 9 , wherein the arm connection element extends through the first member between a pivot point of the bell crank and a proximal end of an elongate body of the first member.
11 . The handle of claim 4 , wherein the pair of arms forms an angle greater than 90 degrees and less than 180 degrees.
12 . The handle of claim 1 , wherein the second member is configured to move toward the first member to configure the handle in a closed state and move away from the first member to configure the handle in an open state.
13 . The handle of claim 12 , wherein the first member and the second member form an angle that is less than 90 degrees in the open state.
14 . The handle of claim 1 , wherein the second member comprises a finger-securing portion disposed on a surface of the second member that faces in a direction that the second member moves away from the first member.
15 . The handle of claim 1 , wherein the first member comprises a holder configured to hold a portion of the outer elongate member.
16 . A medical device comprising:
an outer elongate member;
an inner elongate member movably disposed within the outer elongate member, each of the outer elongate member and the inner elongate member longitudinally extending from a proximal portion to a distal portion;
a distal end effector coupled to a distal end of the elongate inner member; and
a handle coupled to the proximal portion, the handle comprising a first member and a second member,
wherein the outer and inner elongate members project from a distal end of the first member, and
wherein the first and second members are configured to pivot relative to each other to longitudinally move the outer and inner elongate members relative to each other.
17 . The medical device of claim 16 , wherein the first member and the second member are connected to each other via a hinge about which the first member and the second member pivot relative to each other.
18 . The medical device of claim 17 , wherein the second member comprises a bell crank integrated with the hinge.
19 . The medical device of claim 16 , wherein the first member comprises an elongate body, and a holder configured to hold a portion of the outer elongate member, wherein the outer and inner elongate members form a loop between a distal end of the elongate body and the holder.
20 . The medical device of claim 16 , wherein the distal end effector comprises a clip assembly.
