Abstract
An endoscopic system having a shaft, a sheath disposed at least partially inside the shaft having a distal end with a leading surface and an inner surface, the leading surface at the distal end of the sheath having rounded edges so as to be atraumatic, an instrument at least partially inside the sheath and movable relative to the sheath along a longitudinal direction of the sheath, the inner surface being sloped so as to deflect the instrument at a predetermined angle as it is moved into contact with the inner surface and out of the sheath, and the sheath being rotatable relative to the shaft so as to change the direction at which the instrument extends from the sheath.
Claims19
An endoscopic system comprising:
- a shaft;
- a sheath rotatable relative to the shaft and disposed at least partially inside the shaft, the sheath having a distal end with a leading surface and an inner surface;
- an instrument provided at least partially inside the sheath and movable relative to the sheath along a longitudinal direction of the sheath;
- and
- a handle disposed at a proximal end of the shaft, the handle having a control knob that is slidable to control a longitudinal position of the instrument relative to the sheath, the control knob being (i) rotatable to control a rotational position of the sheath and the inner surface relative to the shaft and (ii) lockable to releasably lock the instrument and sheath in position,
- wherein the inner surface of the sheath is sloped so as to deflect a distal end of the instrument at a predetermined angle out of the sheath as the distal end of the instrument is longitudinally moved into contact with the inner surface, and
- wherein the inner surface is configured to, responsive to rotational motion of the sheath by the control knob, be rotated to directionally position the predetermined angle that the distal end of the instrument extends out of the sheath.
An endoscopic system comprising:
- a shaft;
- an imaging device disposed at a distal end of the shaft;
- a light source configured to provide light to the distal end of the shaft;
- a sheath disposed at least partially inside the shaft, the sheath having a distal end with a leading surface and an inner surface, the sheath being rotatable relative to the shaft;
- an instrument provided at least partially inside the sheath and movable relative to the sheath along a longitudinal direction of the sheath;
- and
- a handle disposed at a proximal end of the shaft, the handle having a control knob that is slidable to control a longitudinal position of the instrument relative to the sheath, the control knob being (i) rotatable to control a rotational position of the sheath and the inner surface relative to the shaft and (ii) lockable to releasably lock the instrument and sheath in position;
- wherein the inner surface is sloped so as to deflect a distal end of the instrument at a predetermined angle as the distal end of the instrument is longitudinally moved into contact with the inner surface and deflected at the predetermined angle out of the sheath, and
- wherein the inner surface is configured to, responsive to rotational motion of the sheath by the control knob, be rotated to directionally position the predetermined angle that the distal end of the instrument extends out of the sheath.
