A hysteroscopy system includes a scope having an internal channel, a sheath removably coupled to the scope, and an outflow channel. The sheath has a distal flange extending internally towards an outer surface of the scope. The outflow channel is formed between an inner surface of the sheath and an outer surface of the scope. The distal flange forms a distal end of the outflow channel and is generally located between the scope and the sheath.

1. A hysteroscopy system, the system comprising: a scope having an outer surface and an internal channel defined by an inner surface;a sheath removably coupled to the scope and having a tip at which a distal flange extends internally in a protruding manner towards the outer surface of the scope, the sheath further having an inner surface;an outflow channel formed between the inner surface of the sheath and the outer surface of the scope, the distal flange extending internally in the protruding manner to form a distal end of the outflow channel between the scope and the sheath;an operative channel formed within the internal channel of the scope; anda visualization channel formed adjacent to the operative channel,wherein the distal flange and the sheath are monolithic, a first edge portion of the distal flange facing towards the scope protrudes a first distance towards the outer surface of the scope in a radial direction, a second edge portion of the distal flange facing towards the scope protrudes a second distance towards the outer surface of the scope in the radial direction, and the first distance is different than the second distance. 2. The hysteroscopy system of claim 1, further comprising a surgical tool inserted within the operative channel, the surgical tool being selected from a group consisting of a rotary morcellator, a reciprocating morcellator, or a rotary and reciprocating morcellator. 3. The hysteroscopy system of claim 1, wherein the visualization channel is configured for receiving a visualization device. 4. The hysteroscopy system of claim 1, further comprising an operative member inserted within the scope, the operative member having an outer surface and an internal channel. 5. The hysteroscopy system of claim 4, wherein the outer surface of the operative member has a generally D-shape. 6. The hysteroscopy system of claim 4, further comprising a tool inserted within the internal channel of the operative member. 7. The hysteroscopy system of claim 6, further comprising a fluid flowing through the internal channel of the operative member, the fluid flowing between the tool and the internal channel of the operative member. 8. The hysteroscopy system of claim 1, wherein the sheath has an outer diameter of about 5.6 millimeters and a long diameter of the scope is about 5.15 millimeters. 9. The hysteroscopy system of claim 1, wherein the distal flange extends internally in the protruding manner towards the outer surface of the scope such that an internal diameter of a proximal end of the sheath is greater than an internal diameter of the distal flange. 10. A hysteroscopy system, the system comprising: a scope having an outer surface and an inner surface relative to a radial direction of the scope, the inner surface defining an inflow channel and the outer surface being continuous through a distal end of the hysteroscopy system;a sheath removably coupled to the scope, the sheath having an outer surface and an inner surface relative to the radial direction, the sheath further having a distal flange protruding from the inner surface of the sheath and towards the outer surface of the scope at the distal end of the hysteroscopy system; andan outflow channel formed between the inner surface of the sheath and the outer surface of the scope, the distal flange engaging the outer surface of the scope to form an end of the outflow channel between the scope and the sheath at the distal end of the hysteroscopy system,wherein the distal flange and the sheath are monolithic, a first edge portion of the distal flange facing towards the scope protrudes a first distance towards the outer surface of the scope in the radial direction, a second edge portion of the distal flange facing towards the scope protrudes a second distance towards the outer surface of the scope in the radial direction, and the first distance is different than the second distance. 11. The hysteroscopy system of claim 10, wherein the distal flange has an oval shape with a non-uniform diameter. 12. The hysteroscopy system of claim 11, wherein the oval shape has two opposite sides that extend a greater distance internally towards the center of the scope than two other opposite sides. 13. The hysteroscopy system of claim 10, wherein the sheath has an outer diameter of about 5.6 millimeters and a long diameter of the scope is about 5.15 millimeters. 14. The hysteroscopy system of claim 10, wherein the sheath further includes a plurality of outflow holes near the distal flange. 15. The hysteroscopy system of claim 10, further comprising a visualization channel formed within the internal surface of the scope. 16. The hysteroscopy system of claim 15, further comprising a visualization device inserted within the visualization channel.
