Abstract

A device and method for removing irregular tissue bodies from the skin comprising a tubular member with an internal blade edge positioned adjacent to either or both of its ends. One or both ends have continuously curved cross-section defining an internal blade edge. The edge is moved in a reciprocating fashion. An elongated plunge member larger than the tubular member permits a user to remove the cut and stored irregular tissue material. The central through opening is optionally filled with a suitable substance to enhance or complement the cutting action of the blade.

Description

    OTHER RELATED APPLICATIONS
  • The present application is a continuation-in-part of pending U.S. patent application Ser. No. 10/877,219, filed on Jun. 25, 2004, which in turn is based on provisional application No. 60/483,062, filed on Jun. 30, 2003, which are hereby incorporated by reference.
  • II. BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to a device for removing callouses and other undesirable tissues such as corns, cuticle, and the like, and more particularly, to such a device that includes a circular blade.
  • 2. Description of the Related Art
  • Several designs for removing callous tissues have been designed in the past. None of them, however, includes a circular blade scalpel that is safe and easy to use with efficient results capable of differentiating between the dead (to be removed) and live (to remain) tissues. Many of the instruments used today are quite aggressive, and more so in the hands of inexperienced users. The prior art devices do not discriminate between the calloused tissues and the healthy ones.
  • Applicant believes that the closest reference corresponds to U.S. Pat. No. 4,246,914 issued to Keyser for an abrasive relief device for the foot. However, it differs from the present invention because a circular blade is not disclosed or suggested nor does it include a feature capable of differentiating between the dead and live cells.
  • Another reference corresponds to U.S. Pat. No. 954,325 issued to Moore for a manicuring instrument. The device differs from the claimed invention herein in that it teaches a device with sharp pointed edges, used at various angles for aggressive cutting of the tissues. Moore's patent device does not teach the perpendicular use of the device, nor the necessary structure of the device, to smoothly discriminate between dead and healthy tissues.
  • Other patents describing the closest subject matter provide for a number of more or less complicated features that fail to solve the problem in an efficient and economical way. None of these patents suggest the novel features of the present invention.
  • III. SUMMARY OF THE INVENTION
  • It is one of the main objects of the present invention to provide a device for removing callouses and the extraneous overgrown tissues.
  • It is another object of this invention to provide such a device that is safe and easy to operate even by untrained users.
  • It is still another object of the present invention to provide a device that can be readily cleaned and sterilized.
  • Another object of this invention is to provide a novel method for removing callouses and other extraneous tissues effectively.
  • It is yet another object of this invention to provide such a device that is inexpensive to manufacture and maintain while retaining its effectiveness.
  • Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.
  • IV. BRIEF DESCRIPTION OF THE DRAWINGS
  • With the above and other related objects in view, the invention consists in the details of construction and combination of parts as will be more fully understood from the following description, when read in conjunction with the accompanying drawings in which:
  • FIG. 1 represents a partial elevational view of the device as it is used to remove undesirable tissues C.
  • FIG. 2 shows the device shown in FIG. 1 after irregular tissue C has been removed and blade member 24 slides freely without resistance.
  • FIG. 3 illustrates the use of the present invention.
  • FIG. 4 is a representation of the tubular member with a cooperating plunge member.
  • V. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring now to the drawings, where the present invention is generally referred to with numeral 10, it can be observed that it basically includes a tubular member 20 with a central through opening 26. Member 20 has ends 21 and 22, as best seen in FIG. 3. At least one of these two ends has internal blade edge 24. Device 10 includes central through opening 26 that extends from end 21 to end 22. Central through opening 26 is designed to permit a user to fill the space with a suitable substance such as a skin softener, antiseptic product, or any other equivalent product, if desired.
  • Blade edge 24 is located at the lowermost end of inner wall 23 of tubular member 20, adjacent to end 21 and optionally to end 22 also. Blade edge 24 is located at either or both ends 21 and 22. From the inner side of ends 21 and 22 they extend outwardly with a continuously curved cross-section, as best seen in FIGS. 1 and 2. Blade edge 24 is sharp enough to scrape the irregularities formed on the surface of skin S where device 10 is used. A reciprocating movement in the target area causes edge 24 to scrape across any protruding irregularities. Once the target area has been smoothed out by removing the dead cells, the resulting surface is smooth. This smooth surface permits blade edge 24 to glide over the healthy skin area without obstruction. A user can readily detect this loss of resistance signaling the removal of irregular dead tissues. This avoids irritating the live cells adjacent to the target area.
  • Device 10, as it is moved along skin S, causes the latter to deflect. Callous tissues deflect less and are thus exposed to the scraping action of blade edge 24. Conversely, as the callous tissue is removed, blade edge 24 slides with less resistance and grip.
  • A plunger member 40 has a cooperative diameter smaller than the inner diameter of through opening 26. Member 40 is, in the preferred embodiment, longer than tubular member 20 so that it can be inserted inside through opening 26 and protrude through end 21 or end 22 to push out the collected tissue material. The material of members 20 and 40 is selected so that it meets rigidity standards while compatible with sterilization processes. Steel has been one of such material even though other metals with similar characteristics can also be used. Additionally, many hardened plastic materials can be used.
  • One of the preferred methods for using the present invention is to use a wetting substance. Tubular member 20 can be at lease partially filled with a wetting substance W specially if in gel form. Plunger member 40 can be used to push out wetting substance W, as needed.
  • The method for using device 10 includes initially identifying and, optionally, wetting the target area. Applying in reciprocating movement to one end, with a cutting edge, in a substantially perpendicular relationship with respect to the target area.
  • One other application for the present invention is to use device 10 with animals. Depending on the particular application the diameter of tubular member 20 can be varied.
  • The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments may be made of the inventive concept of this invention. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
