Abstract
Description
- The present invention relates to phacoemulsification surgery and more particularly to a device that better regulates pressure experienced in the eye during cataract surgery.
- The human eye functions to provide vision by transmitting light through a clear outer portion called the cornea, and focusing the image by way of a crystalline lens onto a retina. The quality of the focused image depends on many factors including the size and shape of the eye, and the transparency of the cornea and the lens. When age or disease causes the lens to become less transparent, vision deteriorates because of the diminished light which can be transmitted to the retina. This deficiency in the lens of the eye is medically known as a cataract. An accepted treatment for this condition is surgical removal of the lens and replacement of the lens function by an artificial intraocular lens (IOL).
- In the United States, the majority of cataractous lenses are removed by a surgical technique called phacoemulsification. A typical surgical hand piece suitable for phacoemulsification procedures consists of an ultrasonically driven phacoemulsification hand piece, an attached hollow cutting needle surrounded by an irrigating sleeve, and an electronic control console. The hand piece assembly is attached to the control console by an electric cable and flexible tubing. Through the electric cable, the console varies the power level transmitted by the hand piece to the attached cutting needle. The flexible tubing supplies irrigation fluid to the surgical site and draws aspiration fluid from the eye through the hand piece assembly.
- The operative part in a typical hand piece is a centrally located, hollow resonating bar or horn directly attached to a set of piezoelectric crystals. The crystals supply the required ultrasonic vibration needed to drive both the horn and the attached cutting needle during phacoemulsification, and are controlled by the console. The crystal/horn assembly is suspended within the hollow body or shell of the hand piece by flexible mountings. The hand piece body terminates in a reduced diameter portion or nosecone at the body's distal end. Typically, the nosecone is externally threaded to accept the hollow irrigation sleeve, which surrounds most of the length of the cutting needle. Likewise, the horn bore is internally threaded at its distal end to receive the external threads of the cutting tip. The irrigation sleeve also has an internally threaded bore that is screwed onto the external threads of the nosecone. The cutting needle is adjusted so that its tip projects only a predetermined amount past the open end of the irrigating sleeve.
- During the phacoemulsification procedure, the tip of the cutting needle and the end of the irrigation sleeve are inserted into the anterior segment of the eye through a small incision in the outer tissue of the eye. The surgeon brings the tip of the cutting needle into contact with the lens of the eye, so that the vibrating tip fragments the lens. The resulting fragments are aspirated out of the eye through the interior bore of the cutting needle, along with irrigation solution provided to the eye during the procedure, and into a waste reservoir.
- Throughout the procedure, irrigating fluid is pumped into the eye, passing between the irrigation sleeve and the cutting needle and exiting into the eye at the tip of the irrigation sleeve and/or from one or more ports, or openings, cut into the irrigation sleeve near its end. This irrigating fluid is critical, as it prevents the collapse of the eye during the removal of the emulsified lens. The irrigating fluid also protects the eye tissues from the heat generated by the vibrating of the ultrasonic cutting needle. Furthermore, the irrigating fluid suspends the fragments of the emulsified lens for aspiration from the eye.
- A common phenomenon during a phacoemulsification procedure arises from the varying flow rates that occur throughout the surgical procedure. Varying flow rates result in varying pressure losses in the irrigation fluid path from the irrigation fluid supply to the eye, thus causing changes in pressure in the anterior chamber (also referred to as Intra-Ocular Pressure or IOP.) Higher flow rates result in greater pressure losses and lower IOP. As IOP lowers, the operating space within the eye diminishes.
- Another common complication during the phacoemulsification process arises from a blockage, or occlusion, of the aspirating needle. As the irrigation fluid and emulsified tissue is aspirated away from the interior of the eye through the hollow cutting needle, pieces of tissue that are larger than the diameter of the needle's bore may become clogged in the needle's tip. While the tip is clogged, vacuum pressure builds up within the tip. The resulting drop in pressure in the anterior chamber in the eye when the clog is removed is known as post-occlusion surge. This post-occlusion surge can, in some cases, cause a relatively large quantity of fluid and tissue to be aspirated out of the eye too quickly, potentially causing the eye to collapse and/or causing the lens capsule to be torn.
- Various techniques, such as venting the aspiration line, have been designed to reduce this surge. However, there remains a need for improved phacoemulsification devices that reduce post-occlusion surge as well as maintain a stable IOP throughout varying flow conditions.

Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like parts.
FIG. 1 is a diagram of the components in the fluid path of a phacoemulsification system including a hand piece with an integrated aspiration pump according to the principles of the present invention.FIG. 1 depicts the fluid path through theeye 145 during cataract surgery. The components include anirrigation source 120, an optionalirrigation pressure sensor 130, anoptional irrigation valve 135, anirrigation line 140, ahand piece 150, anaspiration line 155, an optionalaspiration pressure sensor 160, anoptional vent valve 165, apump 170, areservoir 175 and adrain bag 180. Theirrigation line 140 provides irrigation fluid to theeye 145 during cataract surgery. Theaspiration line 155 removes fluid and emulsified lens particles from the eye during cataract surgery.- When irrigation fluid
exits irrigation source 120, it travels throughirrigation line 140 and into theeye 145. Anirrigation pressure sensor 130 measures the pressure of the irrigation fluid inirrigation line 140. Anoptional irrigation valve 135 is also provided for on/off control of irrigation.Irrigation pressure sensor 130 is implemented by any of a number of commercially available fluid pressure sensors. - A
hand piece 150 is placed in relation to theeye 145 during a phacoemulsification procedure. Thehand piece 150 has a hollow needle (270 inFIGS. 2 & 3 ) that is ultrasonically vibrated in the eye to break up the diseased lens. A sleeve located around the needle provides irrigation fluid fromirrigation line 140. The irrigation fluid passes through the space between the outside of the needle and the inside of the sleeve. Fluid and lens particles are aspirated through the hollow needle. In this manner, the interior passage of the hollow needle is fluidly coupled toaspiration line 155. Pump170 draws the aspirated fluid from theeye 145. An optionalaspiration pressure sensor 160 measures the pressure in the aspiration line. An optional vent valve can be used to vent the vacuum created bypump 170. The aspirated fluid passes throughreservoir 175 and intodrain bag 180. FIG. 2 is a block diagram of a phacoemulsification hand piece with an integrated aspiration pump according to the principles of the present invention. InFIG. 2 ,hand piece 150 comprisesmotor 210,shaft 220,removable cartridge 230, optionalaspiration pressure sensor 160,driver 250,horn 260,needle 270, andaspiration line 280.Motor 210 rotatesshaft 220. When the pump is in operation,removable cartridge 230 is held againstshaft 220.Aspiration pressure sensor 160 is located betweenremovable cartridge 230 and theeye 145.- In
FIG. 2 , thepump 170 comprisesmotor 210,shaft 220, and flexible tubing inremovable cartridge 230. In one embodiment of the present invention,shaft 220 has a spiral structure that presses against the flexible tubing inremovable cartridge 230. In this manner, a screw-type or scroll-type aspiration pump is implemented withmotor 210,shaft 220, and flexible tubing inremovable cartridge 230. This is more clearly shown and described inFIGS. 4 and 5 . Whilepump 170 is described as a screw-type pump, other types of pumps may also be used. Aspiration line 280 is fluidly coupled toremovable cartridge 230. Aspiration line also extends through or around drive250,horn 260, andneedle 270. A lumen inneedle 270 is fluidly coupled toaspiration line 280. As described above, fluid and lens particles are aspirated through the lumen ofneedle 270.Aspiration pump 170 draws fluid and lens particles through the lumen ofneedle 270.Driver 250 is typically an ultrasonic driver that produces ultrasonic vibrations inhorn 260.Horn 260 is typically a mass of metal that is coupled todriver 250 andneedle 270. In this manner, vibrations produced bydriver 250 are transferred to horn260 and toneedle 270.Needle 270 is placed in the eye and vibrated to fragment a cataractous lens.Aspiration pressure sensor 160 measures the aspiration pressure inaspiration line 280. While shown as located betweenremovable cartridge 230 anddriver 250, aspiration pressure sensor may be located at any location betweenpump 170 and theeye 145.Aspiration pressure sensor 160 may be implemented by any of a number of known pressure sensor devices.FIG. 3 is a block diagram of a phacoemulsification hand piece with an integrated aspiration pump according to the principles of the present invention. The example ofFIG. 3 has the elements ofFIG. 2 plus anoptional vent valve 165. Whenoptional vent valve 165 is present, it acts to provide a venting path for theaspiration pump 170. In this manner, pump170 can be vented, for example, to atmosphere whenvent valve 165 is opened. As shown inFIG. 3 ,aspiration line 280 has two paths—one path that goes throughremovable cartridge 230, and another path that goes aroundremovable cartridge 230. This second path (that goes around removable cartridge230) and associatedvent valve 165 may also be incorporated intoremovable cartridge 230. Whenvent valve 165 is opened, the aspiration or vacuum produced bypump 170 is decreased as a result of it being vented to atmosphere.FIGS. 4 and 5 are side and cross section views, respectively, of a portion of a phacoemulsification hand piece with an integrated aspiration pump according to the principles of the present invention.FIGS. 4 and 5 more clearly show the details of one example of aremovable cartridge 230 and pump170. In the example shown,removable cartridge 230 comprisesaspiration line coupling 405,first tubing coupling 420,tubing holder 440, andlever 430. These components are integrated into a frame as shown.Removable cartridge 230 can be removed from the remainder of the hand piece.- In the example of the removable cartridge shown in
FIGS. 4 and 5 ,aspiration line coupling 405 can be attached to aspiration tubing that is coupled to the surgical console. In this manner,aspiration line coupling 405 is near the end of the hand piece that is connected to the surgical console. A tube extends fromaspiration line coupling 405 tofirst tubing coupling 420. This tube is a part of theaspiration line 280 shown inFIGS. 2 and 3 . Tubing holder 440 holds a flexible tube (not shown) that is located betweenshaft 220 andtubing holder 440.Shaft 220 presses the flexible tubing againsttubing holder 440. Asshaft 220 rotates, the spiral protrusion onshaft 220 pumps fluid through the flexible tubing (thus implementing a screw-type or scroll-type pump).Tubing holder 440 is made of a rigid material that is suitable for holding flexible tubing. One end of the flexible tubing is fluidly coupled tofirst tubing coupling 420, and the other end of the flexible tubing is fluidly coupled tosecond tubing coupling 425. In this manner, the flexible tubing is a part of theaspiration line 280.Lever 430 operates to secureremovable cartridge 230 to the remainder of the hand piece. While shown as a lever, other mechanisms can be employed to secure removable cartridge to the remainder of the hand piece.Motor 210 is coupled toshaft 220 and serves to rotateshaft 220.Motor 210 can be controlled to control the movement ofshaft 220 as more clearly described below.Motor 210 is typically a DC motor but can be any type of motor or driver suitable forrotating shaft 220.- In the example of
FIGS. 4 and 5 , aconnector 450 connects the flexible tubing held bytubing holder 440 to thehand piece coupling 415.Connector coupling 410 interfaces withhand piece coupling 415—either directly or via another part. In this manner, the aspiration path passes throughhand piece coupling 415,connector coupling 410,connector 450,second tubing coupling 425, the flexible tubing held bytubing holder 440,first tubing coupling 420 andaspiration line coupling 405.Connector 450 is connected to an end ofshaft 220. In this manner,connector 450,shaft 220, and motor210 (along with the frame that holds these parts) is attached to the driver250 (which is coupled to thehorn 260 and the needle270). - The length of aspiration line between the pump and the eye (i.e. between
second tubing coupling 425 and needle270) is minimal (on the order of inches). In addition, this length of aspiration line between the pump and the eye may be non-compliant (i.e. it can be rigid). Having a small length of non-compliant tubing between thepump 170 and the eye eliminates the surge associated with prior art systems. - In operation,
motor 210 rotatesshaft 220. A controller (not shown) controls the operation ofmotor 210. In this manner,shaft 220 may be rotated at any desired speed to produce any desired vacuum. Further,shaft 220 may be stopped or rotated in an opposite direction if desired. In this manner,motor 210 may be controlled to rotateshaft 220 in either direction. When rotated,shaft 220 draws fluid through the flexible tube and acts to pump the fluid through the aspiration line. - In another example,
shaft 220 can be moved toward and away fromtubing holder 440. In this manner, the space betweentubing holder 440 andshaft 220 can be varied so that the flexible tubing can be pinched to different degrees betweenshaft 220 andtubing holder 440. In other words,shaft 220 can pinch the flexible tubing held bytubing holder 440 very tightly to produce pumping action that does not allow for leakage. Alternatively, asshaft 220 is moved away fromtubing holder 440, the flexible tubing is pinched less tightly thus leading to a leakage and less of a vacuum or pumping force. The position ofshaft 220 with respect totubing holder 440 can be variably controlled to adjust the leakage through the flexible tubing, and in turn adjust the vacuum produced by the pump. - In another example (shown in
FIG. 3 ), the position ofshaft 220 with respect totubing holder 440 can be fixed, and avent valve 165 can be used to produce leakage that adjusts the vacuum produced by the pump. In this manner, ventvalve 165 can be variably controlled to control the amount of vacuum that is present in the aspiration line (by controlling the amount of leakage through vent valve165). - The control of aspiration vacuum can be based on a reading from
aspiration pressure sensor 160.Aspiration pressure sensor 160 is located between the pump and the eye. In this manner,aspiration pressure sensor 160 accurately reads the pressure conditions in the aspiration line very close to the eye. Such a reading can be used to precisely control the aspiration vacuum that is applied to the eye. FIGS. 6 and 7 are side and perspective views, respectively, of a removable cartridge for use with a phacoemulsification hand piece with an integrated aspiration pump according to the principles of the present invention. In the example ofFIGS. 6 and 7 , the removable cartridge comprises aspiration line coupling,405,first tubing coupling 420,tubing holder 440,lever 430, andopening 605. Opening605 interfaces withsecond tubing coupling 425 as shown inFIG. 5 . A piece of flexible tubing is located betweenfirst tubing coupling 420 andopening 605. Theremovable cartridge 230 ofFIGS. 6 and 7 can be reusable or disposable. In one example, the removable cartridge is reusable and the flexible tubing in disposable. In another example, the removable cartridge is disposable along with the flexible tubing.- The design of the present invention allows for the
aspiration pump 170 to be very close to theeye 145. The distance between theaspiration pump 170 and theeye 145 can be made to be very small—on the order of inches. Placing theaspiration pump 170 close to theeye 145 allows for a very short length of aspiration line to be located between thepump 170 and theeye 145. Moreover, the length of aspiration line located between thepump 170 and theeye 145 can be rigid (for example, it can be made of stainless steel). This short length of non-compliant material that makes up the aspiration line between thepump 170 and theeye 145 eliminates any surge effect associated with conventional phacoemulsification systems. - In conventional phacoemulsification systems, the aspiration pump is located in a console. A relatively long length of flexible tubing (six feet or more) is located between the aspiration pump and the eye. This relatively long length of flexible tubing has a lot of compliance—it can stretch in response to changes in vacuum pressure. This compliance results in surges as previously described. By incorporating the aspiration pump in the hand piece (and placing it very close to the eye) and having a very short length of non-compliant tubing between the aspiration pump and the eye, these surges can be eliminated, thus resulting in a safer and more efficient surgery.
- From the above, it may be appreciated that the present invention provides a pressurized infusion system for phacoemulsification surgery. The present invention provides an irrigation squeeze band device that more precisely controls fluid pressure. The present invention is illustrated herein by example, and various modifications may be made by a person of ordinary skill in the art.
- Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the invention being indicated by the following claims.
