Abstract
Abstract A laser surgical device that utilizes a continuous wave laser that has a wavelength such that the laser beam when focused at the surface of the tissue or point of contact is nearly totally absorbed at the surface to thereby allow the device to function as a cutting instrument without having adverse effects upon other portions of the body or tissues that are beneath the surface. The laser is mounted for movement so that a physician can manually manipulate the laser beam in a back and forth motion to make an opening of desired depth. The laser also has controls for controlling the length of time the laser is on and the power that is supplied to the laser.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
139 words
A laser surgical device comprising a continuous wave laser of the type that can be operated continuously for at least several minutes, said laser having an output beam, said output beam being of a wavelength such that it is substantially totally absorbed at the surface of tissue; mounting means connected to said laser so as to allow it to be positioned in desired locations; receiving means disposed relative to said laser to receive the output beam of said laser, focus it, and direct the focused beam to a desired area of said tissue; and control means connected to the laser so as to control various output characteristics of said laser and allow a physician to manipulate the laser beam and make a surface incision with the laser surgical device by directing the laser beam along the surface of tissue.
Claim 2
Dependent Claim
139 words
A laser surgical device comprising a continuous wave laser of the type that can be operated continuously for at least several minutes, said laser having an output beam, said output beam being of a wavelength such that it is substantially totally absorbed at the surface of tissue; mounting means connected to said laser so as to allow it to be positioned in desired locations; receiving means disposed relative to said laser to receive the output beam of said laser, focus it, and direct the focused beam to a desired area of said tissue; and control means connected to the laser so as to control various output characteristics of said laser and allow a physician to manipulate the laser beam and make a surface incision with the laser surgical device by directing the laser beam along the surface of tissue.
Claim 3
Dependent Claim
18 words
A laser surgical device as set forth in claim 1, wherein said laser is a CO2-N2 gas laser.
Claim 4
Dependent Claim
51 words
A laser surgical device as set forth in claim 1, wherein said control means has a controllable power supply means connected to said laser to provide power thereto, and a timer unit connected to said power supply means so as to connect and disconnect the power supply means to the laser.
Claim 5
Dependent Claim
43 words
A laser surgical device as set forth in claim 3, wherein said control means further comprises trigger means connected to said timer unit and remotely positioned relative to said timer unit to allow the timer unit to be started from the remote position.
Claim 6
Dependent Claim
18 words
A laser surgical device as set forth in claim 4, wherein said laser is a CO2-N2 gas laser.
Claim 7
Dependent Claim
37 words
A laser surgical device as set forth 5, further comprising a controllable shutter means positioned between said receiving means and said laser means and shutter trigger means connected to the shutter means for controlling the shutter means.
Claim 8
Dependent Claim
37 words
A laser surgical device as set forth 5, further comprising a controllable shutter means positioned between said receiving means and said laser means and shutter trigger means connected to the shutter means for controlling the shutter means.
Claim 9
Dependent Claim
108 words
A laser surgical device as set forth in claim 1, wherein said mounting means is a movable carriage means for positioning the laser, receiving means, and, therefore, the output beam when a large movement of the focused beam is desired; and said receiving means has a focusing means with a handle attached thereto, a universal connection between said carriage and said handle and said focusing means, said focusing means being movable by said handle relative to the output beam so as to provide for smaller movements of the focused beam, whereby both large and small movements of said focused beam may be made by movements of said handle.
Claim 10
Dependent Claim
44 words
A laser surgical device as set forth in claim 7, wherein said receiving means further contains a diaphragm means positioned between the laser and the focusing means so as to control the spot size of the beam from the laser to the focusing means.
Claim 11
Dependent Claim
82 words
A laser surgical device as set forth in claim 8, wherein said receiving means is a container positioned around at least an output end of said laser, said focusing means and said diaphragm means being located inside said container, said container having angles in its shape so as to locate the focusing means at a desired position relative to the laser, and reflecting means located inside the container so as to reflect the output beam of the laser towards said focusing means.
Claim 12
Dependent Claim
18 words
A laser surgical device as set forth in claim 9, wherein said laser is a CO2-N2 gas laser.
Claim 13
Dependent Claim
98 words
A laser surgical device as set forth in claim 10, wherein said control means contains a controllable power supply means; a protection device, said power supply means being connected to the laser through said protection device, said protection device being adapted to connect and disconnect the power supply means to the laser; and a controllable timer unit having trigger means connected to said timer unit so as to start said timer unit, and said timer unit being connected to said power supply means and said protection device to connect and disconnect said power supply means to the laser.
Claim 14
Dependent Claim
136 words
A laser surgical device comprising a high-power continuous wave CO2-N2 gas laser having an output beam; receiving means adapted to receive the output beam of said laser; mounting means connected to said laser and said receiving means; control means connected to the laser so as to control various output characteristics of said laser; and focusing means in said receiving means for focusing the output beam comprising a reflecting means with a handle universally jointed to said receiving means for universally adjusting said reflecting means and thereby direct the output beam to desired location; means disposed in said reflecting means for focusing the output beam; and a diaphragm disposed inside said receiving means between the laser and the focusing means so as to control the spot size of the beam from the laser to the focusing means.
Claim 15
Dependent Claim
136 words
