Abstract
Abstract An autoclavable surgical instrument for directly illuminating interior portions of a human body having a distal end for insertion into a body cavity and a proximal end including a handle portion, a fiber optics device extending from a point adjacent the distal end to a proximal end adjacent the handle portion, and a powerpack unit including a light source, and means removably mounting that unit on the handle portion to position the light source in cooperative relationship with the proximal end of the fiber optics device; lens means being interposed between the light source and the fiber optics device, and means for mounting the lens means on the handle portion to cooperate with the power pack unit to properly position the latter relative to the fiber optics device.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
166 words
An autoclavable powerpack unit for directly illuminating interior portions of a human body, comprising a cylindrical heatresistant metal casing having separable sections including a forward section housing a light bulb and including means allowing light from said bulb to be directed outwardly from said casing, a central tubular section housing electric cell means, and a rear section having an axial bore, the ends of said central section being threaded on their inner surfaces and the rear end of said forward section and the forward end of said rear section being threaded on their outer surfaces and screwed into said central section, a control switch member threadedly engaging the bore of said rear section and extending therethrough for selective engagement with said electric cell means to electrically interconnect said casing and said cell means to provide electrical power to said bulb, and heat- and pressure-resistant seals interposed, respectively, between the bulb and the casing, the control switch member and the casing, and adjacent sections of said casing.
Claim 2
Dependent Claim
166 words
An autoclavable powerpack unit for directly illuminating interior portions of a human body, comprising a cylindrical heatresistant metal casing having separable sections including a forward section housing a light bulb and including means allowing light from said bulb to be directed outwardly from said casing, a central tubular section housing electric cell means, and a rear section having an axial bore, the ends of said central section being threaded on their inner surfaces and the rear end of said forward section and the forward end of said rear section being threaded on their outer surfaces and screwed into said central section, a control switch member threadedly engaging the bore of said rear section and extending therethrough for selective engagement with said electric cell means to electrically interconnect said casing and said cell means to provide electrical power to said bulb, and heat- and pressure-resistant seals interposed, respectively, between the bulb and the casing, the control switch member and the casing, and adjacent sections of said casing.
Claim 3
Dependent Claim
22 words
An autoclavable unit according to claim 1, wherein said casing sections are of stainless steel and said seals comprise silicone rubber O-rings.
Claim 4
Dependent Claim
62 words
An autoclavable unit according to claim 1, wherein the end of said casing receiving said bulb is provided with an open-ended longitudinal recess comprising said means allowing light to be directed outwardly by collecting and directing outwardly light rays emanating from said bulb and also is adapted to receive the end of a fiber optics device for introducing said light rays thereto.
Claim 5
Dependent Claim
72 words
In combination with the autoclavable powerpack unit of claim 1, a surgical instrument having an end portion insertable into a human body cavity, a fiber optics device having a distal end connected to said end portion and a proximal end for receiving light rays, and means removably mounting said unit on said instrument to position and retain said light bulb in cooperative relationship with the proximal end of said fiber optics device.
Claim 6
Dependent Claim
36 words
An autoclavable surgical instrument according to claim 4, wherein said surgical instrument comprises a handle portion and said handle portion, said powerpack unit and said mounting means cooperate to provide handle means for manipulating the instrument.
Claim 7
Dependent Claim
24 words
In an autoclavable surgical instrument according to claim 4, means mounted on the exterior of said casing for frictional engagement with said mounting means.
Claim 8
Dependent Claim
149 words
An autoclavable surgical instrument for directly illuminating interior portions of a human body, comprising a distal end for insertion into a body cavity, a proximal end including a handle portion, a fiber optics device connected to said distal end and extending from a point adjacent said distal end to a proximal end adjacent said handle portion, a powerpack unit including a light bulb, and means removably mounting said unit on said handle portion to position said light bulb in cooperative relationship with the proximal end of said fiber optics device, said powerpack unit including electric cell means, a casing having separable screw threadedly interengaged sections for housing said cell means and said light bulb and including means allowing light from said bulb to be directed outwardly from said casing, and heat and pressure resistant seals interposed between said bulb and said casing and between adjacent sections of said casing.
Claim 9
Dependent Claim
149 words
An autoclavable surgical instrument for directly illuminating interior portions of a human body, comprising a distal end for insertion into a body cavity, a proximal end including a handle portion, a fiber optics device connected to said distal end and extending from a point adjacent said distal end to a proximal end adjacent said handle portion, a powerpack unit including a light bulb, and means removably mounting said unit on said handle portion to position said light bulb in cooperative relationship with the proximal end of said fiber optics device, said powerpack unit including electric cell means, a casing having separable screw threadedly interengaged sections for housing said cell means and said light bulb and including means allowing light from said bulb to be directed outwardly from said casing, and heat and pressure resistant seals interposed between said bulb and said casing and between adjacent sections of said casing.
Claim 10
Dependent Claim
66 words
In an autoclavable surgical instrument according to claim 7, lens means interposed between said light bulb and the proximal end of said fiber optics device for focusing light rays emanating from the former onto the latter, means for mounting said lens means on said handle portion which is adapted to cooperate with said powerpack unit to properly position the latter relative to said fiber optics device.
Claim 11
Dependent Claim
21 words
An autoclavable surgical instrument according to claim 7, wherein said mounting means comprises a device for clampingly engaging said handle portion.
Claim 12
Dependent Claim
36 words
In an autoclavable surgical instrument according to claim 9, means disposed adjacent said distal end thereof for adjustably positioning the distal end of said fiber optics device to facilitate selective focusing of the light emanating therefrom.
