Hysteroscopic system

摘要

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; and a 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.
