Abstract: A surgical instrument includes an outer tubular sleeve configured to receive a middle tubular member coaxially therethrough to define an irrigation pathway therebetween and therealong. An inner tubular shaft is rotatably received within the middle tubular member, a distal end of the inner tubular shaft forming a surgical bur configured to cut tissue or bone upon rotation thereof. One or more fluid exit ports is defined at the end of the irrigation passageway between the distal end of the outer tubular sleeve and the distal end of the middle tubular member. The fluid port(s) is configured to direct irrigation fluid in a narrow stream toward the surgical bur. The annular space between each respective fluid exit port at the end of the irrigation passageway is sealed to prevent irrigation fluid from leaking and obscuring the surgeon's view of the surgical bur.

Abstract: In implementation of techniques for template-based behaviors in machine learning, a computing device implements a template system to receive a digital video and data executable to generate animated content. The template system determines a location within a frame of the digital video to place the animated content using a machine learning model. The template system then renders the animated content within the frame of the digital video at the location determined by the machine learning model. The template system then displays the rendered animated content within the frame of the digital video in a user interface.

The shock wave device includes an outer covering and an inner member inner connected at a distal end of the device. First and second conductive wires extend along the length of the device within the volume between the outer covering and the inner member.
