Definitions

  • the present invention involves a novel and useful surgical abrading device which is particularly applicable to eye surgery.
  • particulate matter which is usually cellular material
  • Such epithelial cells or opacities if left behind, tend to grow and spread, which results in the clouding of the normally clear interior or posterior capsular walls.
  • a disorganized mass grows in the form of "pearls" which results in a secondary cataract, ie., a clouding of the visual axis.
  • the posterior capsule was cut with a fine needle-knife or a laser beam to clear the central optical zone of the shell.
  • correcting of a secondary cataract condition requires a second surgical procedure, an undesirable step.
  • United States patent 5,084,005 teaches a swab structure including a polymeric foam with grooves for collecting biological samples.
  • a surgical tool which is capable of clearing the posterior capsule of cellular matter following extra capsular cataract surgery to obviate the need for correcting a secondary cataract condition, would be a notable advance in the surgical field.
  • a novel and useful surgical abrading device and method is herein provided which is particularly useful in cataract surgery.
  • the present invention is deemed to encompass an element which possesses a resilient body having an outer surface intended for abrading biological material held to a membranous surface.
  • the element may take the form of an open or closed cell foam plastic material with an outer surface that includes a multiplicity of recesses or pocks, which are particularly effective in removing biological material held to a membranous surface.
  • One particular application of the present invention concerns its use in extra capsular cataract surgery. Following removal of the clouded natural lens (a cataract) , softer cortical material remains and must be removed to avoid subsequent growth of the same, which can form a secondary cataract.
  • a relatively rigid implement which may take the form of an elongated tube, is also employed in the present invention.
  • the relatively rigid implement is capable of being manipulated by the user, which is normally the surgeon in the case of eye surgery.
  • the relatively rigid implement attaches to the element by means for connecting the same to the resilient body of the element. Such connection may take place by any suitable means such as fusion heating, sonic welding, gluing, and the like.
  • the resilient body may partially or completely surround the relatively rigid implement.
  • the relatively rigid implement may be simply connected to a portion of the outer surface, which is employed for abrading biological material from the membranous surface.
  • connection means permits the outer surface of the resilient body to be available for abrading or scrubbing of biological material from the membranous surface.
  • the relatively rigid implement may include an angulation which allows the surgeon to reach remote areas of the interior of the lens capsule, in the case of eye surgery.
  • the relatively rigid element may comprise a tube.
  • Irrigation means may also be found in the present invention for transporting fluid from a fluid source to the tube and through the tube, into the capsule of the eye.
  • the capsule is inflated with fluid flowing through the tube during the scrubbing process.
  • the resilient body of the element may include the characteristic of being absorbent to irrigation fluids, although this is not a necessity in the present case.
  • the irrigation means may be attached to the relatively rigid implements and lie adjacent the element during use.
  • the relatively rigid implement may take the form of a forceps having a tubular member attached to one of the legs of the forceps.
  • the invention may also encompass a method of removing biological material held to a translucent lens capsule found in the eye.
  • the surgeon would enter the capsule with the element having a resilient body with an outer surface intended for abrading biological material held to the membranous surface of the lens capsule.
  • the element would be connected to the relatively rigid implement for this purpose.
  • the surgeon then rubs or abrades the outer surface of the resilient body against the biological material held to the translucent membrane of the capsule until the biological material is free of the membranous surface.
  • the free biological material is then removed by irrigation and/or aspiration devices, or by any other suitable means, from the interior of the capsule. Irrigation is also employed in the method of the present invention to maintain the inflation of the capsule during the abrading process.
  • the lens capsule is suitable for insertion of an intraocular lens to correct aphakia resulting from cataract removal.
  • a further object of the present invention is to provide a surgical abrading device and method which is capable of removing harmful biological material from a membranous surface such as a lens capsule of an eye without damaging or harming the membranous surface in any manner.
  • Yet another object of the present invention is to provide a surgical abrading device and method which may be combined with an irrigation system to maintain inflation of an eye capsule while the device of the present invention is employed.
  • Another object of the present invention is to provide a surgical abrading device and method which is capable of removing invisible and microscopic biological material from the interior of a lens capsule following cataract removal during eye surgery.
  • FIG. 1 is a side elevational view of the device of the present invention in use within a lens capsule following removal of the cataract, the capsule depicted in section.
  • FIG. 2 is a side elevational view of the device of the present invention.
  • FIG. 3 is a sectional view taken along line 3-3 of Fig. 2.
  • FIG. 4 is a partial side elevational view of a second embodiment of the present invention.
  • FIG. 5 is a partial side elevational view of a third embodiment of the present invention.
  • FIG. 7 is a partial side elevational view of a fifth embodiment of the present invention.
  • device 10A includes as one of its portions an element 12.
  • Element 12 possesses a resilient body 14 having an outer surface 16 which is intended for abrading biological material 16 from a membranous surface 18, Figs. 2 and 3.
  • membranous surface 18 takes the form of the posterior surface of a transparent lens capsule 20 found in an eye.
  • the capsule 20 also includes an anterior inner surface 22.
  • Transparent capsule 20 is generally in the form of an oblate spheroid and further includes fornices 24 and 26.
  • Scrubbing element 12 may be formed of open or closed cell sponge like material.
  • poly vinyl alcohol polymer is suitable for the formation of element 12.
  • Other materials may suffice in this regard also, such as various foam plastic materials, felt, wool, and the like.
  • Element 12 possesses an outer surface 30 having a plurality of recesses or pocks 32 which aid in the scraping process and will be described hereinafter.
  • Implement 34 is also employed in the present invention.
  • Implement 34 is constructed of a relatively rigid material, when compared to resilient body 14 of element 12.
  • implement 34 may take the form of a tube 36 having a first portion 38 and a second portion 40 which are connected to one another at angulation 42. End 44 of second portion 40 extends free of the outer surface 30 of element 12.
  • First portion 38 of tube 36 is formed to a hub 46 which is capable of transporting fluid from a fluid source 48, shown schematically in Fig. 1.
  • fluid source 48, hub 46, and tube 34 constitute irrigation means 50 for passing fluid from source 48 through end 44 of tube 36.
  • Directional arrow 52 indicates that passage of such fluids, which may be saline solution, air, and the like, through hub 46.
  • Directional arrow 54 indicates the passage of fluid from end 44.
  • Means 54 is also depicted in the drawings for connecting element 12 to implement 34.
  • Fig. 3 it may be observed that implement 34 has been fused to element 12.
  • Fused layer 56 is indicated as a thickened line on Fig. 3 for this purpose.
  • Other methods may be employed to connect implement 34 to element 12 such as sonic welding, gluing, and the like.
  • element 12 includes ridges 58 and 60 which form a channel 62 that partially surrounds implement 34.
  • Embodiment 10B includes a relatively rigid implement 34 which is attached to the outer surface 64 of scrubbing element 66. End 68 of relatively rigid implement 34 extends outwardly from surface 64. Fusion of implement 34 to scrubbing element 66 forms a shallow channel 70.
  • Resilient scrubbing element 78 includes a lower rounded portion 80 and a diminished cap portion 82 which is heat fused to implement 34.
  • Fig. 7 illustrates embodiment 10E of the present invention where relatively rigid implement 34 is passed through a resilient scrubbing element 84 and held to the same by heat fusion shown as a thickened portion 86 surrounding implement 34 on Fig. 8.
  • Resilient scrubbing element 84 completely surrounds implement 34 in this case. However, end 68 of implement 34 is still free of resilient scrubbing element 84.
  • Fig. 9 shows embodiment 10F of the present invention where resilient scrubbing element 88 is held by a relatively rigid implement in the form of forceps 90.
  • Irrigation tube 92 and hub 94 are held to leg 96 of forceps 90 by glue, welding, and the like.
  • hub 94 connects to source of irrigation fluid 48 in a manner similar to that of embodiment 10A of Fig. 1.
  • resilient scrubbing elements 66, 74, 78, 84, and 88 of embodiments 10B-F may be formed of material similar to resilient element 12 such that the outer surface of each is capable of removing biological material 16 from surfaces 18, 22, and fornices 24 and 26 of capsule 20, in the same manner as embodiment 10A of Fig. 1.
  • Resilient element 12 is located within fornix 26 in Fig. 1 and is able to effect scrubbing in that area through the use of angulation 42 on relatively rigid implement 34. It has been found that resilient element 12 is capable of removing visible and microscopic biological matter during this operation. In additional, element 12 may be pressed vigorously against the interior surfaces 18, 22, and fornices 24 and 26 of capsule 20 without breaking the capsule. Irrigation means 50 may be employed to maintain the inflation of capsule 20 during this procedure. After scrubbing by device 10A, aspiration tube 100 is inserted to capsule 20 to remove biological matter 16 from the interior 28 of capsule 20 following abrasion of the same from capsule 20. Capsule 20 is then available for insertion of an intraocular lens. It has been found that device 10A greatly reduces the need for secondary cataract procedures normally employed in the prior art devices and methods associated with cataract surgery.
