Abstract
ABSTRACT OF THE DISCLOSURE
A laser surgical system for use in the operating room is suspended on the ceiling and can be moved horizontally in an X-Y direction. The system has the laser tubes, power supplies and cooling unit in the suspended assembly. A carbon dioxide laser for cutting and a neodymium YAG laser for coagulation excite a common optical channel. A third laser argon, or other wave-length, can be added to the system. The common optical channel couples the laser beams to an articulate arm delivery system, or a microscope micromanipulator deliv-ery system or fiberoptics delivery system.
The microscopic micromanipulator delivery sys-tem is motorized so it can be easily moved in any direc-tion. This motorized system is also compatible with a microprocessor for automated surgery. The system also has a built-in digital television system for demon-stration, recording or as a robotic eye for association with a computer that may help control the laser surgery.

Description
:~2~93~L3 LASER SURGERY
The present invention relates in general to laser surgery and more particularly concerns novel appa-ratus and techni~ues for performing a wide variety of 5 surgical procedures iTl an operating room with precision and reduced trauma for patients while facilitating obser-vation and recordation through the use of laser sources of different wavelengths transmittable to a patient over a common optical path that ;s also observable by the 10 surgeon.
As an example of prior art laser surgical appa-ratus reference is made to U. S. Patent Nos. 3~487,835, 3,528,424, 3,642,007, 3,659,613, 3,769,963, 3,796,220, 3,865,113, 3,865,114, 3,910,276, 4,069,823, 4,170,997 and 15 4,174,154.
It is an important object of this invention to provide a.n improved laser surgical system.
According to the invention, there i.s means defi.ning a common opti.cal path for e~xchang-i.n~ opti.cal 20 energy with a pat:i.ent on an operltiflg table, at le~ast first and secoflcl lflse~r sources of dlf~erent wavelength, means for coupling the first and second laser sources to the common optical path, and means for selectively posi-tioning the common optical path. Preferably, there is 25 optical obsérving means, such as a microscope, and means for coupling the optical observing means to the common optical path. Preferably the apparatus is suspended over the operating table from rails that facilitate X-Y
~2~g3~3 movement in the horizontal plane, and the common optical path comprises a telescoping assembly that allows move-ment in the Z direction. The system may include vents, an aspirator and a fiberoptic lighting system for illu-5 minating with sterile disposable plastic covers.Preferably one of the laser sources is a carbon dioxide laser for cutting and a second is a neodymium YAG laser for coagulation, or evaporation.
Numerous other features, objects and advantages 10 of the invention will become apparent from the following specification when read in connection with the accom-panying drawing in which:
FIG. 1 is a perspective view of an embodiment of the invention in an operating room;
FIG. 2 is a diagrammatic plan view of an em~
bodiment of the invention illustrating the location of various system components; and FIG. 3 is a diagrammatic representation of an exemplary optical system according to the invention help-20 ful in understanding how the different optical signalsenter the cornmon optical path.
With reference now to the drawing and more particularly FIG. 1 thereof, there is a shown a per-spective view of a multipurpose multiwavelength surgical 25 laser system suspended from X rails 11 and 12 and Y rails 13 and 14. X rails 11 and 12 support Y rails 13 and 14 which support housing 15. Housing 15 includes the lasers with associated power supplies, controllers and cooling systems and supports accessory operating room light 16 30 and other elements in the system posltionable in X, Y and Z as described ~elow. A stationary column 118 depends from housing 15 and accommodates telescoping column 113 comprising a common optical path for transmitting energy from a lasér source and allowing the surgeon to observe 35 the incision. A motor (not shown) may provide mechanical energy for lowering and raising the telescoping structure 113 as indicated by arrows A in accordance with ~2~9313 well-known techniques, not described in detail herein to avoid obscuring the principles of the invention, when actuated by an appropriate control button on switch pad 112 to provide Z-axis positioning.
A microscopic delivery system arm 110 selec-tively angularly displaced about its fixed end by motor 114, as indicated by arro~s D-D, and manually rotatable about vertical and horizontal axes, as indicated by ; arrows B and C, is carried by and optically coupled to - 10 end section 121 and includes a microscope 115 with variable magnification. A switch pad 112 controls motor 114 to selectively raise and lower the delivery arm 110 with fine and coarse adjustment in accordance with well-known techniques. Switch pad 112 may be used to effect 15 X-Y positioning of the apparatus by releasing brakes, such as 102, to allow manual movement. Electromechanical I brake 102, which may be of conventional type, mechanically grasps the rail 11 when deenergized, and the solenoid acts against a spring when a solenoid is 20 energized to release the brake and allow movement, there-by normally keeping the assembly stationary for obser-vation and/or cutting, and/or coagulating. The brakes for rails 13 and 14 are not visible in FIG. 1 and are in ; cabinet 15. Air piston shock absorbers, such as 103X and 25 103Y, cushion the chock when the assembly reaches the ends of a pair of rails.
A television camera 119 provides a television signal of what is observed through microscope 115 for display on television monitor 120 ancl may also cle]iver 30 this signal to a harcl copy printer or video recorder system Eor recording. Television camera 119 may also comprise a robotic eye when the invention is used in con-nection with an automatic control system to, for example, guide and control the cutting laser along a predetermined 35 path.
The invention may also include an articulated arm delivery system 107 terminating in a hand piece 3~
coupler assembly 108 which may be used by a surgeon in a manner analogous to a scalpel, while using laser energy not only or cutting, but also for coagulating. A hand piece may be coupled to system 107 by a short fiberoptics 5 coupler. This coupling arrangement is shown magnified as optical input jack 108A, fiberoptic cable 108B and endoscope 108C.
The apparatus is suspended above an operating table 2] above a patient 22 where it may be conveniently 10 controlled by a surgeon having access to control panel 109, microscope 115, joystick 117 with a trigger switch on its end and/or a footswitch (not shown) and switch pad 112. Actuating the trigger switch or footswitch typically operates shutter A or B (FIG. 3) to allow laser 15 energy from an associated laser to enter the common optical path as described below. Keyboard 116 on control panel 109 may be used to enter appropriate commands for CW and/or pulsed operation of the 1asers or other information when the apparatus is used in connection with 20 a computer. Meters 111 indicate appropriate power level operating information, or laser potentials and/or currents.
An optical switch 106 allows manual direction of laser energy selectively into the telescoping assembly 25 below or the articulated arm 107. Power cables 104 pro-vide electrical power to the lasers and associated equipment in housing 15. Water hoses 105 provide water for cooling.
Referring to ~IG. 2, there is shown a cliagram-30 matic representation of units lrl ho~lsi.ng 1.5. Ilousirlg 15may inc]ude an allrlirlg laser wil:h power supply 202, carbon dioxide laser 203, cooling package 205 and 207, carbon dioxide laser power supply 206, neodyrnium YAG laser 204~
neodymium YAG laser power supply 208 anci a conventional 35 control unit 209, containing relays, interlocks, circuit breakers, controls for the operating modes of the lasers and the like. Optical port 201 admits laser beam energy 3~L3 to the telescope below.
Re~erring to FIG. 3, there is shown a diagram-matic representation of the optical system according to the invention. He~e or Argon laser 202 illuminates a 45D
5 reflector 302 that deflects the beam along the axis 31 of the telescoping section below through coated mirrors 304 and 305. Coated mirror 304 receives the laser beam from neodymium YAG laser 204 through focusing lens 301.
Perforated mirror 305 receives the laser beam from C02 10 laser 203. With reflecting mirror 306 actuated by switch 106 (FIG. 1) positioned as shown, 45~ coated mirrors 308 and 309 deflect one or more active beams through focusable turret 310 upon movable mirror 311 and through perforated collimating lens 316 of the microscope to 15 patient 22. Turret 310 includes three lenses; one for C2 laser and aiming light, the second for Nd-YAG laser and aiming light, and the third a compromise for all wavelengths. The first two are interlocked so that only the associated ]aser can operate when a respective lens 20 is positionecl along the common optical path. The surgeon may then observe through microscope 31~ the effect of the laser on the patient while controlling its position with joystick 117. The perforation on axis of lens 316 passes the laser beam freely while the remaining portion acts as 25 a collimating lens for viewing and recording. The micro-scope may also include an indicator for power output, lasers then ~eing used and interlock indicator.
Electromechanica] shutters A and ~ intercept the outputs of Nd-YAG and C02 lasc!rs 2()4 and 203 30 respectively wit:h a 45" mirror to also lurlcl-iorl as a heat sink power meter element when positioned as sllown in accordance with well-known techniques.
With reflecting mirror 306 positionecl as repre-sented by dotted line 306b~ the active laser beam is 35 directed upon reflecting mirror 307 into articulated arm delivery system 107.
Joystick 117 moves mirror 311 to facilitate ~ ~193~L3 aiming the beam where desired. Altenlatively, X-Y
controller 3~3 preferably includes stepping motors for positioning mirror 311. Optics 314 preferably includes an interloc~ed protective optic filter interposed when 5 Nd-YAG laser 204 or other high power laser is being used.
Television camera 119 preferably receives an optical image of the area of the patient being treated surgically through a 45 prism 317 and zoom lens 318 of a known type not described in detail to avoid obscuring the 10 principles of the invention.
The invention has a number of advantages. It provides a multipurpose multiwavelength laser system having the flexibility to deliver one or more beams under precise convenient practical control of the operating 15 surgeon while being compatible with computer operation.
It may be installed in a dedicated operating room that allows the surgeon to develop new procedures where in whole, or in part, the laser surgical system may be used to achieve more precision and less invasive surgery. The 20 invention is also compatible with diagnostic instru-mentation having computer storage in which stored diagnostic information may be processed for automatic or semiautomatic surgery. Then, suitable stepping motors or other drives may be included for controlling rnovement 25 along directions B and C as well as A and D. For exam-ple, information of a CAT scan or NMR of the patient in computer storage may be processed and utilized to assist the surgeon in removing tissue more uniformly and speedily.
It is evident that those skilled in the surgical and other technical arts may now make numerous uses and modifications of and departures from the specific apparatus and techniques described herein without departing from the inventive concepts.
35 Consequently, the invention is to be construed as embracing each and every novel feature and novel com-bination of fe.~tures present in or possessed by the apparatus and techniques herein disclosed and limited solely by the spirit and scope of the appended claims.

The first two are interlocked so that only the associated ]aser can operate when a respective lens 20 is positionecl along the common optical path. The surgeon may then observe through microscope 31~ the effect of the laser on the patient while controlling its position with joystick 117. The perforation on axis of lens 316 passes the laser beam freely while the remaining portion acts as 25 a collimating lens for viewing and recording. The micro-scope may also include an indicator for power output, lasers then ~eing used and interlock indicator.
Electromechanica] shutters A and ~ intercept the outputs of Nd-YAG and C02 lasc!rs 2()4 and 203 30 respectively wit:h a 45" mirror to also lurlcl-iorl as a heat sink power meter element when positioned as sllown in accordance with well-known techniques.
With reflecting mirror 306 positionecl as repre-sented by dotted line 306b~ the active laser beam is 35 directed upon reflecting mirror 307 into articulated arm delivery system 107.
Joystick 117 moves mirror 311 to facilitate ~ ~193~L3 aiming the beam where desired. Altenlatively, X-Y
controller 3~3 preferably includes stepping motors for positioning mirror 311. Optics 314 preferably includes an interloc~ed protective optic filter interposed when 5 Nd-YAG laser 204 or other high power laser is being used.
Television camera 119 preferably receives an optical image of the area of the patient being treated surgically through a 45 prism 317 and zoom lens 318 of a known type not described in detail to avoid obscuring the 10 principles of the invention.
The invention has a number of advantages. It provides a multipurpose multiwavelength laser system having the flexibility to deliver one or more beams under precise convenient practical control of the operating 15 surgeon while being compatible with computer operation.
It may be installed in a dedicated operating room that allows the surgeon to develop new procedures where in whole, or in part, the laser surgical system may be used to achieve more precision and less invasive surgery. The 20 invention is also compatible with diagnostic instru-mentation having computer storage in which stored diagnostic information may be processed for automatic or semiautomatic surgery. Then, suitable stepping motors or other drives may be included for controlling rnovement 25 along directions B and C as well as A and D. For exam-ple, information of a CAT scan or NMR of the patient in computer storage may be processed and utilized to assist the surgeon in removing tissue more uniformly and speedily.
It is evident that those skilled in the surgical and other technical arts may now make numerous uses and modifications of and departures from the specific apparatus and techniques described herein without departing from the inventive concepts.
35 Consequently, the invention is to be construed as embracing each and every novel feature and novel com-bination of fe.~tures present in or possessed by the apparatus and techniques herein disclosed and limited solely by the spirit and scope of the appended claims.
