Devices and methods for suture placement
A suturing device includes a handle, an elongate body, an actuator and a needle holder. The handle includes a proximal handle end and a distal handle end. The elongate body connects with the handle and includes a proximal end portion and a distal end portion. The actuator is operable between a first operating position and a second operating position. The actuator includes a manually operated member including an operator contact surface spaced from the proximal handle end in a direction toward the distal handle end. The needle holder includes a distal end section having a distal-most tip and defines a needle passage and a distal opening adjacent the distal-most tip. The needle passage is configured to receive at least a portion of an associated needle when the actuator is in the first operating position.
1. A suturing device comprising:
a handle including a proximal handle end and a distal handle end;
an elongate body connected with the handle, the elongate body including a proximal end portion and a distal end portion;
an actuator interacting with the elongate body and operable between a first operating position and a second operating position, the actuator including a trigger including an operator contact surface spaced from the proximal handle end in a direction toward the distal handle end, wherein the trigger pivots with respect to the handle, and the actuator further includes a slider connected with the trigger such that pivotal movement of the trigger results in the slider moving coaxial or parallel with a longitudinal axis of the elongate body and a flexure bearing element connecting the trigger with the slider; and
a needle holder extending away from the distal end portion or provided as part of the distal end portion of the elongate body, the needle holder including a distal end section having a distal-most tip and defining a needle passage and a distal opening adjacent the distal-most tip, the needle passage being configured to receive at least a portion of an associated needle when the actuator is in the first operating position.
2. The suturing device of claim 1 , wherein the elongate body has a configuration that defines a proximal end portion longitudinal axis and a distal end portion longitudinal axis both residing in an elongate body plane, wherein a line emanating from the center of the handle through the operator contact surface is offset an internal angle between 5 degrees and 85 degrees from the elongate body plane.
3. The suturing device of claim 1 , wherein the needle holder is a curved needle holder defining a curved needle passage following a curved needle passage radius, wherein a line emanating from the center of the handle through the operator contact surface is offset an internal angle between 5 degrees and 85 degrees from a plane in which the curved needle passage radius resides.
4. The suturing device of claim 1 , wherein the flexure bearing element is a resilient living hinge.
5. The suturing device of claim 1 , wherein the flexure bearing element biases the trigger radially outwardly from the longitudinal axis.
