1. A suturing device for minimally invasive surgery, comprising:
a housing;
an actuator displaceably coupled to a first portion of the housing;
a shaft extending from a proximal end to a distal end along a shaft axis, wherein the proximal end of the shaft is coupled to a second portion of the housing, wherein the shaft includes one or more interior surfaces defining an interior portion;
a needle extending from a proximal end to a distal end about a needle axis, wherein a first portion of the needle is coupled to a portion of the actuator such that a displacement of the actuator displaces the needle from a first needle position to a second needle position, and wherein a needle tip is disposed at the distal end of the needle, the needle tip being configured to penetrate a portion of tissue to be sutured; and
a state indicator coupled to a second portion of the needle, the state indicator being operable between a first state and a second state, wherein when the state indicator is in the first state, the state indicator provides a first visual indication, when the state indicator is in the second state, the state indicator provides a second visual indication, wherein the first visual indication is different than the second visual indication, and wherein:
when the needle is in the first needle position and a first rotational position, the state indicator is in the first state providing the first visual indication,
when as the needle translates between the first needle position and the second needle position in a first actuation cycle, (a) the needle rotates about the needle axis from the first rotational position towards a second rotational position, and (b) as the needle rotates about the needle axis from the first rotational position towards the second rotational position, the state indicator rotates between the first state and the second state, and
after the needle has translated from the second needle position and into the first needle position at the completion of the first actuation cycle, the needle is in the second rotational position, and the state indicator is in the second state providing the second visual indication.
