Hysteroscopic system
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 comprising:
a scope having an outer surface and an inner surface, the outer surface having a uniform cross section along a length of the scope;
an operative member within the scope having an outer surface and an inner surface, the inner surface defining an operative channel, and at least part of the outer surface of the operative member and the inner surface of the scope defining a visualization channel; and
a sheath removably coupled to and surrounding the scope, the sheath including a tube defining a longitudinal axis, a distal end of the tube being in a shape of a flange extending perpendicular relative to the longitudinal axis towards the outer surface of the scope, wherein the outer surface of the scope and an inner surface of the tube form an outflow channel, and the flange abuts the outer surface of the scope to form an end of the outflow channel.
2. The hysteroscopy system of claim 1 , wherein a radial cross section of the outer surface of the scope at a distal end of the scope forms a shape with flat symmetrical sides between arcuate symmetrical sides.
3. The hysteropscopy system of claim 1 , wherein the visualization channel is configured to receive a visualization device.
4. The hysteroscopy system of claim 1 , wherein an outer diameter of the sheath is about 5.6 millimeters.
5. The hysteroscopy system of claim 4 , wherein an outer diameter of the scope is about 4.6 to 5.15 millimeters.
6. The hysteroscopy system of claim 1 , wherein a radial cross section of the operative member forms a horizontal D-shape.
7. The hysteroscopy system of claim 1 , further comprising a surgical tool within the operative channel.
