Probe with gripping structure for robotic surgical system
View Patent ↗An argon beam coagulation probe for a robotic surgery system having a body with an argon gas entry port and an argon gas exit port and a pedestal interconnected to the underside of body that includes a pair of opposing arcuate channels that positioned equidistantly about the body. As a result, the argon gas jet exit port will be aligned equidistantly between the two fingers of a robotic arm and the body will be aligned in the same direction as the yaw axis of the robotic arm, so that argon gas will be expelled in the same direction that the fingers are pointing. A surgeon manipulating the robotic arms from the master control can thus easily align the probe based on the positioning of the robotic fingers and will still have the entire range of pitch, yaw, and roll movement of the robotic system.
1. An argon beam coagulation probe, comprising:
a body extending along a longitudinal axis from a proximal end having an argon gas entry port adapted for connection to an argon beam coagulation system to a distal end having a taper than defines an argon gas exit port from which from argon gas and plasma beam may be expelled;
a pedestal interconnected to the body and defining a pair of opposing channels that are positioned equidistantly about the longitudinal axis and that extend longitudinally under the body in an arcuate shape;
wherein the pedestal comprises a central member extending along a plane that encompasses the longitudinal axis and a pair of flanges extending laterally from an end of the central member that is opposite the body and longitudinally along the body relative to the longitudinal axis; and
wherein the body further comprises a pair of shoulders that extend longitudinally along the body relative to the longitudinal axis and are spaced apart from the pair of flanges to define the two opposing channels.
2. The probe of claim 1 , where each of the pair of channels include a first, linear portion toward the proximal end of body and a second, arcuate portion toward the distal end of the body.
3. The probe of claim 2 , wherein the first, linear portion of each of the pair of channels extends toward the longitudinal axis from the proximal end of body to the distal end of the body.
4. The probe of claim 3 , wherein the second, arcuate portion of each of the pair of channels is curved away from the longitudinal axis from the proximal end of body toward the distal end of the body.
5. The probe of claim 4 , wherein the arcuate portion defines a stop providing a predetermined setback distance between the argon gas exit port and the linear portion of the channel in which a robotic finger may be positioned.
6. The probe of claim 5 , wherein the pair of channels are closer together and to the longitudinal axis toward the proximal end of the body than toward the distal end of the body.
