Abstract
Abstract An instrument for surgically removing a solid cone of tissue. An inner cylinder is rotatably fitted within an outer cylinder. Mirrors are mounted inside the inner cylinder and positioned such that a narrowly converging laser beam, traveling down the cylindrical axis, is deviated to exit the instrument in a direction which intersects the cylindrical axis at an acute angle. By rotating the inner cylinder with its mirrors, the exiting laser beam is caused to sweep out a conical surface. In cervical conization, the instrument is inserted so that its distal end is adjacent the cervix and the beam is incident thereon to excise a cone-shaped sample. In one embodiment, an axial guide pin protrudes from the distal end for insertion through the cervical os.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
107 words
A surgical instrument for conization of the cervix uteri, comprising an outer cylinder adapted to be inserted into the vagina toward said curvix uteri, an inner cylinder co-axially arranged within said outer cylinder for rotation with respect thereto about the common cylindrical axis, reflecting means disposed within said inner cylinder and rigidly connected thereto for deviating a beam of energy traveling down said cylindrical axis such that said beam exits said inner cylinder in a direction intersecting said axis at an acute angle, whereby rotation of said inner cylinder causes said exiting beam to sweep out a conical surface thereby isolating a cone-shaped portion of the cervix.
Claim 2
Dependent Claim
107 words
A surgical instrument for conization of the cervix uteri, comprising an outer cylinder adapted to be inserted into the vagina toward said curvix uteri, an inner cylinder co-axially arranged within said outer cylinder for rotation with respect thereto about the common cylindrical axis, reflecting means disposed within said inner cylinder and rigidly connected thereto for deviating a beam of energy traveling down said cylindrical axis such that said beam exits said inner cylinder in a direction intersecting said axis at an acute angle, whereby rotation of said inner cylinder causes said exiting beam to sweep out a conical surface thereby isolating a cone-shaped portion of the cervix.
Claim 3
Dependent Claim
59 words
The instrument of claim 1, wherein said reflecting means includes a first mirror connected to said inner cylinder lying on said axis for deflecting said beam, at least one second mirror connected to said inner cylinder lying off said axis and optically aligned with said first mirror to deflect toward said axis the beam reflected from said first mirror.
Claim 4
Dependent Claim
20 words
The instrument of claim 2, wherein said first and second mirrors are both perpendicular to a plane including said axis.
Claim 5
Dependent Claim
20 words
The instrument of claim 1, further comprising drive means for rotating said inner cylinder with respect to said outer cylinder.
Claim 6
Dependent Claim
34 words
The instrument of claim 4, wherein said drive means includes an annular gear affixed co-axially to said inner cylinder and a pinion drivingly engaging said annular gear rotatably mounted transversely in said outer cylinder.
Claim 7
Dependent Claim
34 words
The instrument of claim 5, wherein said pinion is adapted to be connected to a drive means external to said inner and outer cylinders and said annular gear and pinion are both bevel gears.
Claim 8
Dependent Claim
36 words
The instrument of claim 1, further comprising endoscope means optically aligned with said axis for projecting said beam along said axis toward said reflecting means and for providing a view of said cervix along said axis.
Claim 9
Dependent Claim
29 words
The instrument of claim 7, wherein said endoscope means includes reflector means spaced from said co-axial cylinders lying obliquely on said axis for reflecting said beam along said axis.
Claim 10
Dependent Claim
46 words
The instrument of claim 8, wherein said reflector means includes a plate having a reflective central portion for deflecting said beam facing said reflecting means in said inner cylinder and having a pair of spaced apertures arranged to pass a respective pair of stereo viewing axes.
Claim 11
Dependent Claim
76 words
Apparatus for excising a cone-shaped sample from an object, comprising support means rotatable about an axis, reflecting means for deviating a beam of energy traveling down said axis rigidly connected to said support means for rotation therewith having a beam receiving surface lying on said axis for receiving said beam and a beam reflecting surface displaced from said axis and aligned such that said beam exits in a direction which intersects said axis at an angle.
Claim 12
Dependent Claim
76 words
Apparatus for excising a cone-shaped sample from an object, comprising support means rotatable about an axis, reflecting means for deviating a beam of energy traveling down said axis rigidly connected to said support means for rotation therewith having a beam receiving surface lying on said axis for receiving said beam and a beam reflecting surface displaced from said axis and aligned such that said beam exits in a direction which intersects said axis at an angle.
Claim 13
Dependent Claim
19 words
The apparatus of claim 10, wherein said support means includes a first cylinder whose cylindrical axis forms said axis.
Claim 14
Dependent Claim
31 words
The apparatus of claim 11, further comprising a second cylinder co-axially and rotatably containing said first cylinder, and drive means for rotating said first cylinder with respect to said second cylinder.
Claim 15
Dependent Claim
53 words
The apparatus of claim 10, wherein said receiving surface includes a mirror connected to said support means lying obliquely on said axis and said reflecting surface includes a mirror connected to said support means lying off said axis optically aligned with said first mirror such that said beam is reflected toward said axis.
Claim 16
Dependent Claim
18 words
The apparAtus of claim 13, wherein said mirrors are both perpendicular to a plane passing through said axis.
Claim 17
Dependent Claim
66 words
A surgical instrument for conization of the cervix uteri, comprising a housing adapted to be inserted into the vagina toward said cervix uteri, means for causing a laser beam to exit the distal end of said housing toward said cervix and means for causing said laser beam to move in a predetermined path defining a conical surface whereby a cone-shaped portion of the cervix is excised.
Claim 18
Dependent Claim
66 words
A surgical instrument for conization of the cervix uteri, comprising a housing adapted to be inserted into the vagina toward said cervix uteri, means for causing a laser beam to exit the distal end of said housing toward said cervix and means for causing said laser beam to move in a predetermined path defining a conical surface whereby a cone-shaped portion of the cervix is excised.
