Abstract
This disclosure relates to surgical instruments with selectively rotating handles. In certain aspects, the surgical device includes a conduit having a longitudinal axis and configured to extend into a body lumen, and a handle coupled to the conduit and configured to selectively rotate relative to the conduit. The handle is coupled to the conduit by a connection including a clutch mechanism, and the handle is configured to rotate in response to a user activation of the clutch mechanism.
Claims20
A surgical device comprising:
- (a) a conduit having a longitudinal axis and being configured to extend into a body lumen;
- and
- (b) a handle coupled to the conduit and configured to selectively rotate relative to the conduit, wherein the handle is coupled to the conduit by a connection comprising a clutch mechanism,
- wherein the handle is configured to rotate in response to a user activation of the clutch mechanism.
A resectoscope comprising:
- (a) a conduit having a longitudinal axis and extending through an opening in a handle coupled to the conduit by a connection comprising a clutch mechanism, wherein the handle is configured to selectively rotate relative to the conduit in response to a user activation of the clutch mechanism;
- (b) a surgical tool attached to the conduit and rotationally fixed relative to the conduit;
- (c) an inner sheath releasably attached to the conduit, wherein the inner sheath surrounds at least a portion of the conduit and the surgical tool;
- and
- (d) an outer sheath releasably attached to the inner sheath, wherein the outer sheath surrounds at least a portion of the inner sheath.
A method for examination or treatment within a body cavity or lumen of a patient with a surgical device,
- the method comprising:
- (1) inserting the surgical device into a body cavity or lumen of the patient such that the surgical device extends into the body cavity, wherein the surgical device comprises
- (a) a conduit having a longitudinal axis and extending through an opening in a handle coupled to the conduit, wherein the handle is configured to selectively rotate relative to the conduit and wherein the handle is coupled to the conduit by a connection comprising a clutch mechanism;
- and
- (b) a surgical tool rotationally fixed to the conduit and configured to reciprocate parallel to the surgical device;
- (2) rotating the conduit to position the surgical tool within the body cavity;
- and
- (3) selectively rotating the handle about the conduit in response to a user activation of the clutch mechanism, wherein the handle rotates relative to the conduit and the surgical tool.
