Abstract
The present technology relates to ureteroscopy, laser ablation of ureteral and renal stone, capture and removal of stone fragments. In one embodiment, the device includes an optical instrument operably connected to a large vacuum channel that is about 1.5 mm to about 8.0 mm in width. In another embodiment, the device includes two single-time use disposable or potentially reusable units, such as a large vacuum endoscope removal tip and a wireless and modular battery-powered handpiece.
Claims12
A device, comprising:
- an optical instrument fluidly connected to a single vacuum channel, wherein the optical instrument comprises a central bar disposed only at a distal end of the single vacuum channel across a diameter of the single vacuum channel such that the central bar divides only the distal end of the single vacuum channel into two halves to prevent clogging;
- a plurality of irrigation channels arrayed around an outer circumference of the single vacuum channel;
- an array of optical materials located around the outer circumference of the single vacuum channel for achieving visualization;
- and
- a control mechanism located around the outer circumference of the single vacuum channel for achieving manipulation of the optical instrument;
- wherein the central bar comprises one or more ports, a light source, and one or more optical elements;
- wherein one or more guidewires are disposed through the single vacuum channel and through the one or more ports to promote controlled movement of the optical instrument.
A device, comprising:
- an optical instrument fluidly connected to a single vacuum channel,
- wherein the optical instrument comprises:

- a plurality of irrigation channels arrayed around an outer circumference of the single vacuum channel;
- an array of optical materials located around the outer circumference of the single vacuum channel for achieving visualization;
- and
- a control mechanism located around the outer circumference of the single vacuum channel for achieving manipulation of the optical instrument;
- wherein the central bar comprises one or more ports, a light source, and one or more optical elements;
- wherein one or more guidewires are disposed through the single vacuum channel and through the one or more ports to promote controlled movement of the optical instrument;
- and
- b. removing the biopsied tissue or stone particle or fragment thereof from the individual.
