Abstract
A removable cap for an endoscope used with a surgical laser to improve the stone free rate (SFR) of lithotripsy procedures. The removable cap includes a filter configured to block or filter light of a wavelength like a wavelength of light from an aiming beam generated by the surgical laser.
Claims20
A removable cap for an endoscope, comprising:
- a housing having an open proximal end and a distal end, the open proximal end defining an inner cavity in the housing, the inner cavity dimensioned to fit over a distal end of an endoscope;
- and
- a filter disposed on the distal end of the housing, the filter to align with a camera of the endoscope when the housing is inserted over a distal end of the endoscope.
An endoscopic system, comprising:
- an endoscope comprising a camera assembly disposed in a distal end of the endoscope and at least one working channel in which an optical fiber can be inserted;
- and
- a removable cap for the endoscope, the removable cap comprising:
- a housing having an open proximal end and a distal end, the open proximal end defining an inner cavity in the housing, the inner cavity dimensioned to fit over the distal end of the endoscope;
- and
- a filter disposed in the distal end of the housing, the filter to align with the camera assembly when the housing is inserted over a distal end of the endoscope.
The method of claim 16, further comprising verifying a stone free rate (SFR) based on the images captured with the endoscope camera.
The method of claim 16, the removable cap comprising:
- a housing having an open proximal end and a distal end, the open proximal end defining an inner cavity in the housing, the inner cavity dimensioned to fit over a distal end of an endoscope;
- and
- a filter disposed on the distal end of the housing, the filter to align with a camera of the endoscope when the housing is inserted over a distal end of the endoscope.
The method of claim 16, wherein the filter is a long pass filter (LPF) or a band pass filter (BPF).
A method for a lithotripsy procedure, comprising:
- installing a removable cap over the distal end of an endoscope, the endoscope comprising a camera and the removable cap comprising a filter, wherein the filter optically aligns with the camera;
- positioning the distal end of the endoscope with the removable cap in an environment treated via a lithotripsy procedure;
- activating and aiming beam of a lasing console coupled to an optical fiber disposed in a working channel of the endoscope;
- and
- passing the optical fiber over a treatment area comprising tissue and capture images with the endoscope camera.
