Abstract
A cassette has a top joined with a releasably attached double hinge to a bottom. An interior region can be filled with dental/medical instruments for sterilization and/or storage. The instruments can be supported by pre-arranged supports and retaining members. A practitioner can configure the arrangement in the cassette in accordance with his/her preferences.
Description
- This application claims the benefit of the filing date of U.S. Provisional Application No.60/525,274 filed Nov. 26, 2003, entitled “Configurable Cassettes”.
- The invention pertains to instrument sterilizing cassettes. More particularly, the invention pertains to cassettes of a type that are configurable by a dental practitioner in accordance with his/her preferences in arranging sets of instruments for sterilization, and subsequent use.
- Dental practitioners are known to have very specific preferences as to the arrangement of instruments to be used in a given dental procedure. Differing procedures call for different sets of instruments and different arrangements of those instruments prior to starting the procedure.
- Subsequent to the procedure, the instruments need to be cleaned and sterilized. They also need to be placed into the practitioner's preferred configuration for subsequent use.
- It has been known to load sets of instruments into bags for sterilization subsequent to a procedure. The sterile bag of instruments can then be provided to the practitioner at the start of the next procedure. One of the disadvantages of using sterilization bags is that the instruments are loose in the bag and are not arranged as preferred by the practitioner.
- Dental instrument cassettes represent another approach to sterilizing, and storing arranged instruments for use by a practitioner. Such cassettes can be formed of sterilizable heat resistant plastic or medical grade stainless steel. Known cassettes often have hinged sections which can be closed upon one another to form an interior region. The instruments can be arranged in the interior region for sterilization and storage until the practitioner is ready to use them for the next procedure. When the cassette is opened, the instruments are presented to the practitioner in his/her preferred arrangement.
- Plastic sterilization and storage cassettes have been disclosed in U.S. Pat. No. 4,541,992 entitled “Apparatus for Organizing, Sterilizing and Maintaining Medical/Dental Instruments”, U.S. Pat. No. 5,294,413 entitled “Sterilization and Storage Cassette”, U.S. Pat. No. 5,433,929 entitled “Sterilization and Storage Cassette”. Metal storage cassettes have been disclosed in U.S. Pat. No. 4,854,475 entitled “Instrument Cassette”, U.S. Pat. No. 5,215,726 entitled “Two-Tiered Sterilization and Storage Cassette”, U.S. Pat. No. 5,84,632 entitled “Two-Tiered Sterilization and Storage Cassette”, Des. Patent No. D 441,457 entitled “Sterilization Cassette” and Des. Patent No. D 360,697 entitled “Sterilization Cassette”. The previously enumerated patents are all assigned to the assignee hereof and incorporated by reference herein.
- While the known cassettes have been useful and effective for their intended purposes, there continues to be a need for cassettes which enable dental practitioners to more readily arrange instruments in accordance with their preferences. Preferably such cassettes could also be readily reconfigurable in the event that the practitioner wishes to change the instrument set, or, wants to modify the instrument arrangement. It would also be desirable if the cassettes could be configured so as to have a minimal footprint when opened.

FIGS. 1A, 1B , 1C illustrate different configurations of a dental instrument storage andsterilization cassette 10. As illustrated inFIG. 1A , thecassette 10 includes a cover, an upper, molded,thermoplastic body member 12 a and a base, a lower, moldedthermoplastic body member 12 b. - The
members 12 a, b can be molded of any high strength autoclavable thermoplastic. Alternately, one or both ofmembers 12 a, b can be formed of metal. -
Members 12 a, b when closed against one another, as illustrated inFIG. 1A , define and bound an interior instrument storage region. -
FIG. 1B illustrates thecassette 10 in an open state and having a first instrument configuration 10-1. The configuration 10-1 presents to the practitioner a plurality of instruments I-1 which could be the same or different depending on the procedure with which the instruments are associated. The instruments I-1 are oriented and arranged in the configuration 10-1 with their elongated axes, perpendicular to an elongated axis of each of themembers 12 a, b. The instruments I-1 are supported on removable and rearrangeable silicon based rail assemblies, best seen inFIG. 8F . Other instruments can be retained by one or more base rail anchors 18, or clips and holders, best seen inFIGS. 8A, 8B and 8C. - The upper region or cover 12 a,
FIG. 1B , carries a removably attached compression rail indicated generally at 22. When thecover 12 a is closed against the base 12 b, the compression rail 22 clamps the instruments I-1 against the respectivebase rail assemblies 16 a, b thereupon blocking any movement of the respective instruments during sterilization, transportation to the location for the procedure, or, during storage between procedures. - The
base rail assemblies 16 a, b are either directly coupled to or indirectly coupled to the base 12 b via base rail anchors 18, by engaging various members of an elongated plurality of openings, such as therepresentative opening 26 inbase 12 b. Theopenings 26 are spaced axially along the base 12 b. Shorter openings 26-1 are spaced axially along the base 12 b and provide additional locations to which therails 16 a,b and/or base rail anchors 18, clips or instrument holders can be attached. - The
cover 12 a also includes a plurality of circular perforations such asrepresentative perforation 28. It will be understood that the elongated perforations oropenings 26, 26-1 andcircular openings 28 not only facilitate locating and attachment of various instrument support elements, they also contribute to and facilitate sterilization of the instruments carried in thecassette 10 when in a closed state, such as inFIG. 1A . - It will also be understood that the
cover 12 a andbase 12 b could be identical. In this configuration, theperforations 26, 26-1 and 28 would also be identical. - Clips for hinged instruments, such as
clips openings 28 in accordance with the practitioner's preferences. A hinged instrument, such as scissors I-2 can be carried by the hinged instrument clips such as 32 a, b. As will be understood by those of skill in the art, the hinged instrument clips as well as the instruments for rails and rail base anchors can be arranged in a variety of configurations relative tocovers 12 a andbase 12 b. These arrangements are preferably based on the preference of the practitioner. - An alternate instrument configuration 10-2 is illustrated in
FIG. 1C . InFIG. 1C , a plurality of instruments I-3 is supported on respective base rails, such as 16 a′, 16 b′, which could be identical to the base rails 16 a, b. In the configuration 10-2, the plurality of instruments I-3 extend parallel to the elongated axis of thecassette 10. The instruments I-3 can be retained in place by compression rail 22′ which is retained incircular openings 28. The configuration 10-2 does not include supports 32 a, b. - The
cassette 10 is also advantageous in that a practitioner can initially use insrument configuration 10-1 and subsequently change the same in accordance with his/her preferences. Similarly, the hinged instruments such as instrument I-2 can be added or deleted from the instrument set. - The
cover 12 a andbase 12 b can be latched together with a pair ofelongated latches 38 a, b. Thelatches 38 a, b are preferably carried oncover 12 a. They slidably engage respective latching elements 40 a, b on the base 12 b when thecover 12 a is closed against the base 12 b. Other latch configurations come within the spirit and scope of the invention, for example the latches could be carried on the base 12 b. - Those of skill will understand that instrument configurations 10-1, -2 are exemplary only. Other configurations come within the spirit and scope of the present invention.

FIG. 8F illustrates an exemplary rail assembly 16i.FIG. 8G illustrates a base rail anchor, such asanchor 18. -
FIG. 9 is an exploded view of another instrument configuration 10-3. The configuration 10-3 uses the cover andbase 12 a, b, discussed previously, along with thehinge 44. However, instrument configuration 10-3 is based on incorporating one or more trays such as 66 a,b,c within the region formed by the cover andbase 12 a, b. - For example, and without limitation, instruments can be stored in a deep tray 66 a or one of two
shallow trays 66 b, 66 c. The trays can be retained byresin tie downs 68 which slidably engage posts, such aspost 70 to clamp the respective trays to the base 12 b. - In addition to the trays, hinged instrument clips, such as the
clips 32 i discussed previously, can be slidably attached to thecover 12 a for purposes of carrying one or more hinged instruments as would be understood by those of skill in the art. It will be understood that other tray based instrument storage arrangements come within the spirit and scope of the present invention. It will also be understood that all elements or components usable in thecassette 10 could be formed of resin or metal. - From the foregoing, it will be observed that numerous variations and modifications may be effected without departing from the spirit and scope of the invention. It is to be understood that no limitation with respect to the specific apparatus illustrated herein is intended or should be inferred. It is, of course, intended to cover by the appended claims all such modifications as fall within the scope of the claims.
