摘要： A method of preparing a laser delivery fiber for a therapeutic, treatment, or surgical procedure includes steps of providing an optical fiber having a pre-formed tip; placing a temporary protective sleeve over the pre-formed tip; inserting the optical fiber with the protective sleeve through a handpiece; and, before beginning the therapeutic, treatment, or surgical procedure, removing the protective sleeve from the optical fiber.

摘要： An arrangement that prevents carbonization of cladding, coating, or buffer layers of a surgical laser fiber due to thermal radiation reflected back into the fiber from, or emitted by, a target of the laser, includes a thermal radiation blocking, absorbing or diverting structure. The thermal radiation blocking, absorbing or diverting structure surrounds an end portion of the fiber that has been stripped of one or more coating and/or buffer layers, and may be made of a heat resistant material such as PTFE or polyimide to block heat from reaching the coating or buffer layers, an optical ferrule such as fused silica to guide the heat away from the fiber coating or buffer layers, or a high refraction index material such as UV adhesive.

The end of the fiber, including the thermal radiation blocking, absorbing or diverting structure and, optionally, at least a portion of the coating or buffer layer, may be standoff or protective sleeve structure such as a soft polymer tip or a metal, fused silica, quartz or ceramic ferrule. The standoff or protective sleeve structure may be flush with a tip of the fiber to limit erosion due to contact with the surgical laser target, or extend beyond the fiber to tip to eliminate erosion by preventing initial contact.

摘要： An end-firing surgical laser fiber suitable for Thulium Laser Fiber lithotripsy applications includes an internally reflective tube that extends beyond the distal end surface of the fiber to provide a standoff sleeve, and that is welded or otherwise fixed to an end section of the fiber. The standoff sleeve may be made of silica glass or sapphire, a reflective metal, and/or may include a reflectivity-enhancing coating or structure on an inner surface of the tube. In addition, the reflective standoff sleeve may be tapered to increase or decrease a diameter of a distal end of the sleeve to control output power density, and may include index matched fillers or structures that absorb, transmit, or scatter energy away from the fiber cladding, and/or an energy blocking or absorbing structure positioned at an upstream end of the sleeve. Still further, the laser output may be modified by adding relatively low power, extended duration pulses to a high frequency pulse train in order to clear suspended dust particles from an interior of the sleeve during a lithotripsy procedure, and prevent buildup of the particles on the inside diameter of the sleeve.

摘要： The need for persons to move around a crowded operating room during a surgical procedure is reduced by providing each of the persons tasked with operating surgical equipment, such as a laser, with a portable or handheld communication device capable of transmitting instructions and commands necessary to operate the laser, and by further providing each person in the operating room whose duties require observing a monitor with display devices capable of displaying video and other information shown on the monitor. The handheld wireless communication devices may be smartphones or tablets, and the display devices may be separate wireless display devices or displays of the smartphones or tablets. Operation of the surgical equipment may be by voice commands, allowing the equipment to be controlled while continuously viewing the video and information on the display device

摘要： An end-firing surgical laser fiber suitable for Thulium Laser Fiber lithotripsy applications includes a standoff that extends beyond the distal end surface of the fiber to prevent contact between the end face of the fiber and a targeted stone. The standoff may either (1) extend along only one side of or partially around a circumference of the fiber, so that dust from the pulverized stone can freely flow downstream from the treatment site without being trapped by or accumulating on the standoff, or (2) include at least one flushing port that prevents dust accumulation by permitting passage of dust from within the standoff. Flushing of dust from within the standoff may be facilitated by including a source of fluid to entrain the dust and carry it through the flushing port.

摘要： A first structure made of a first polymer is joined to a second structure made of an incompatible second polymer by the steps of welding small bands of compatible tubing or material to the first structure to create raised structures or ribs, and mechanically linking the second structure with the ribs or raised structures at the desired attachment point. The mechanical linkage may be accomplished by using heat shrinking or mechanical compression (such as crimping) to force the incompatible second polymer around the ribs or raised structures or, in the case of raised structures formed as threads or nubs, by inter-engagement between the threads or nubs on the first structure and corresponding structures, such as internal threading, nub-receiving slots, or internal surfaces, of the second structure. The option of using the welded raised structures as threads or nubs for a threaded, bayonet, pin-and-slot, snap-fit, or similar connection enables the second structure to be removed from the first structure and replaced whenever the second structure becomes worn during use. The first structure may be an surgical laser fiber with an ETFE buffer layer, and the second structure is a protective structure may be made of PTFE, PET, FEP or PFA.

摘要： A method of welding a protective structure to a tip of a surgical laser fiber involves inserting the optical fiber into a length of tubing, and positioning the fiber and the tubing in a rotatable fixture arranged to simultaneously rotate the fiber and tubing while laser radiation is directed through a transparent material of the tubing, so that one or both contacting surfaces of the tubing and the fiber absorb the laser radiation and heat up to weld the tubing to the fiber. The tubing may be a length of polymer material.
