Abstract

A surgical instrument includes a handle assembly and a transmission assembly including an end effector. The end effector includes a visual indicator, such as dots disposed on a clamp arm, to emit light from at least one LED disposed between the clamp arm and a clamp pad. The LED is connectable to a power source. An outer sheath of the end effector is extruded to include a first set of electrical conduits. A distal assembly of the end effector includes the clamp arm, clamp pad, LED, and a second set of electrical conduits to mate with the first set of electrical conduits when the distal assembly is snap-fit into the extruded outer sheath. An ultrasonic surgical instrument includes an outer sheath configured to transmit light from an internally housed LED along portions of the outer sheath.

(a) a body;

(b) a transmission assembly extending distally from the body;

11. The surgical instrument of claim 1, wherein the one or more LEDs emit a glow configured to be emitted in at least one of a series of colors.

12. The surgical instrument of claim 11, wherein each color is associated with a temperature level of a blade of the end effector.

13. An ultrasonic surgical instrument comprising:

(a) a sheath;

(b) an ultrasonic blade extending from the sheath; and

(c) a light source housed in the ultrasonic surgical instrument, wherein the light source is configured to emit light in response to forces exerted at the ultrasonic blade;

wherein the sheath comprises a solid opaque tube and a light pipe tube disposed within the solid opaque tube, and the solid opaque tube comprises elongate localized areas, and wherein light from the light source and light pipe tube are transmitted only through the elongate localized areas.

14. The instrument of claim 13, wherein the localized areas comprise a series of dots.

15. An ultrasonic surgical instrument comprising:

(a) a sheath;

(b) an ultrasonic blade extending from the sheath; and

(c) a light source housed in the ultrasonic surgical instrument, wherein the light source is configured to emit light in response to forces exerted at the ultrasonic blade;
