Suturing assembly providing bi-directional needle movement through uni-directional actuator movement

摘要

A suturing assembly includes shaft attached between a handle and a head. The handle includes a brace and an actuator attached to the handle, where the actuator has a neutral position that is distal the brace. The shaft defines a longitudinal axis of the assembly. The head includes a proximal portion housing a needle that is movable through a needle exit port, and a distal end spaced apart from the proximal portion by a throat. The distal end is radially offset from the longitudinal axis and defines a cavity. Movement of the actuator from the neutral position to the brace moves the needle both in a first direction out of the needle exit port into the cavity and in a second direction out of the cavity and into the needle exit port.
