Device for diagnosing body cavity interior with supersonic waves

Claim 2

A combination endoscope and supersonic diagnostic probe for examining an internal organ within a body cavity comprising: a part adapted to be inserted into said body cavity, said inserted part including a supersonic wave probe tip positioned at its extremity, a flexible portion adjacent to said tip adjustably curvable in a locus plane of curvature, and a window for a perspective endoscope angularly incised in said inserted part above and adjacent to said flexible portion; said supersonic wave probe tip being formed with a window for transmission of supersonic waves in a direction substantially at right angles to said locus plane of curvature and positioned where it may be brought into contact with said organ by manipulation of said flexible portion; and said incised viewing window being so positioned that the observing direction of a perspective endoscope telescopically inserted into said inserted part will be along said locus plane of curvature whereby said supersonic wave probe tip may be observed as it is manipulated to bring said supersonic wave transmission window into contact with said organ.

Claim 3

A combination endoscope and supersonic probe for examining an organ within a body cavity comprising: a part adapted to be inserted within said body cavity including a jacket tube, an articulated flexible member, and a supersonic wave probe tip; said articulated flexible member being connected at one end to said jacket tube and at its other end to said probe tip and having connected thereto an operating wire manipulable to bend said articulated flexible member in a locus plane of curvature; said supersonic wave probe tip including therewithin means for transmitting supersonic waves and having in its surface a window through which said supersonic waves are transmitted and received and adapted to be positioned against said internal organ by the bending of said articulated member; said jacket tube having therewithin a hollow guide tube for receiving a perspective endoscope and having angularly incised in its end adjacent to said articulated flexible member a viewing window angled along said locus plane of curvature in the direction toward which said articulated flexible member bends; and a perspective endoscope telescopically positionable in said hollow guide tube so that its field of vision through said viewing window includes said supersonic wave probe tip window as it is positioned against said internal organ by manipulation of said operating wire.

Claim 4

A combination endoscope and supersonic probe for examining an organ within a body cavity comprising: a part adapted to be inserted within said body cavity including a jacket tube, an articulated flexible member, and a supersonic wave probe tip; said articulated flexible member being connected at one end to said jacket tube and at its other end to said probe tip and having connected thereto an operating wire manipulable to bend said articulated flexible member in a locus plane of curvature; said supersonic wave probe tip including therewithin means for transmitting supersonic waves and having in its surface a window through which said supersonic waves are transmitted and received and adapted to be positioned against said internal organ by the bending of said articulated member; said jacket tube having therewithin a hollow guide tube for receiving a perspective endoscope and having angularly incised in its end adjacent to said articulated flexible member a viewing window angled along said locus plane of curvature in the direction toward which said articulated flexible member bends; and a perspective endoscope telescopically positionable in said hollow guide tube so that its field of vision through said viewing window includes said supersonic wave probe tip window as it is positioned against said internal organ by manipulation of said operating wire.

Claim 5

A combination endoscope and supersonic probe as claimed in claim 2 wherein said viewing window is incised at an acute angle with respect to said jacket tube.

Claim 6

A combination endoscope and supersonic probe as claimed in claim 3 wherein the direction of the supersonic waves transmitted by said supersonic wave probe is at right angles to the direction of the field of vision of said endoscope.
