1. Field of the Invention
The present invention relates to a self-contained unit for holding instruments and components intended for use in dental treatment.
2. Description of the Related Art
The use of units for holding surgical instruments and components that are to be used in various dental connections is already known. For this purpose, the unit can be arranged to hold instruments and components in order for these to be able to be used in the various treatment situations. The unit or units can be the shape of a drawer or box and, for example, can receive and hold various combinations and parts for the various treatment situations on a surface that faces towards the user. Reference can be made to the patent SE 513842, obtained by the same applicant as for the present patent application, and to U.S. Pat. No. 5,518,115 and U.S. Pat. No. 5,525,314 and to the references cited therein.
In accordance with an aspect of at least one of the embodiments disclosed herein is the realization that there is need in the art for a unit that can work as a single unit or as a modular system that will ensure the optimal provision of instruments and components for the various dental treatment situations. In addition, another aspect of at least one of the embodiments disclosed herein is the realization that the total volume of the unit or of the modular system should be limited. For example, a reduction in volume of up to 50% in comparison to currently-known corresponding equipment could be achieved.
Further, the unit or units can be made of a material or have a covering that is easy to hold and can have excellent frictional characteristics in relation to an underlying surface so that during the removal of instruments and components from the respective unit or during the insertion of instruments and components into the respective unit, the unit will not tend to slide on the underlying surface which can otherwise make the removal or insertion of instruments or components more difficult.
In addition, the unit or units can be configured to hold the same or greater numbers of instruments and components. Indeed, the number of instruments and components on the market has a constant tendency to increase and the ease of selection of the instruments and components has been made considerably more difficult on account of the increasing assortment. This means that it can be difficult to select the correct instruments and components.
Therefore, in accordance with another aspect of at least one embodiment disclosed herein is the realization that there is a need for improved access to and organization of sets of instruments and components. Such an improvement can optimize the use of these instruments and components in different types of treatment and with different patients and for different treatments, for example, more general treatment, advanced treatment, specialist treatment, etc. Accordingly, each user may be able to select his assortment from a larger general assortment in a simple way. It must therefore be possible for display arrangements and information labels for recommended treatment stages and for stages carried out in a particular order to be available on or in association with the respective unit.
Some embodiments disclosed herein can also be used to facilitate double utilization of expensive tools. For example, in a modular embodiment, different parts of the unit can be assembled irrespective of whether one or more of the unit parts constitutes or represents a varied collection. Thus a side or top arrangement is to be provided with different or optional top arrangements, that can occur in different variants with regard to the instruments and/or components that are held or that can be held. It is therefore important that the unit or units meet these requirements and make possible the clearest possible arrangement for each user.
In other embodiments, the unit or units can be manufactured using an autoclave at high temperatures. In this regard, various embodiments can be constructed to withstand long periods of use without requiring intermediate service or replacement of parts. Further, the unit or units can have a robust construction in addition to being easy to hold due to frictional characteristics.
An object of the present invention, therefore, is to solve all or parts of the problems described above.
In accordance with some embodiments, the unit can be configured to include side and bottom portions that can form a rigid first unit part. The first unit part can be configured to be completely or partially provided externally with a covering or layer of a non-rigid, flexible, or soft material and can be arranged to be easy to hold and functional. In addition, a top of the unit can form a rigid second unit part that can preferably contain an organized holding arrangement for the instruments and components. In some embodiments, the unit can be constructed of a combination of rigid and flexible or non-rigid/soft material.
The different materials in each unit preferably ar able to withstand temperatures of approximately 135° C., which are encountered during sterilization of the instruments and the components in the unit. In a preferred embodiment, the sides and bottom can be encased in non-rigid or soft material, which can consist of an elastomer (such as silicone). The sides and bottom can be constructed of rigid plastic, but they can also be made of metal. The unit can be constructed with a lid that can be arranged to be removable.
In another embodiment, the unit can be configured to include a support at one end that can be unfolded and folded away. By means of the support, the top surface of the unit can be given an advantageous angle of inclination in relation to a user. The top can be made of metal or plastic and can be provided with labeling that can withstand the above-mentioned temperatures. The unit can be arranged with holes and/or openings for facilitating passage of sterilizing steam therethrough. In some embodiments, the unit can include a unit holding arrangement that can comprise rubber grommets arranged with holes, hook-shaped holding devices and snap-fit devices.
According to the embodiments disclosed herein, the reduction in volume of the unit can be considerable, and the unit can be easy to hold and have a good frictional resistance in relation to the underlying surface upon which the unit is arranged.
In an additional embodiment, the unit can comprise a modular system having a plurality of modular units. The modular units can be arranged in a box that is provided with a lid that can be opened and closed. The box can be configured to hold the modular units securely during, for example, transportation and storage. The modular units can have different breadths and different combinations of different sizes of modular units and can be used in association with the storage box. The respective units can be provided with labeling or information regarding dimensions, different treatment stages, different types of patient, etc.
Therefore, in some embodiments, the unit can be configured to have small external dimensions and hold a relatively large number of instruments and components. Further, the unit can have a construction that is robust and easy to hold, and in addition, can have good frictional characteristics in relation to the underlying surface upon which the unit can be arranged. The unit can comprise an advantageous combination of the rigid and soft materials as mentioned above, such that the rigid material provides robustness and the soft material makes the unit easy to hold and provides frictional characteristics. The unit can also be configured to provide extremely good display information and labeling that can withstand harsh environments in which the unit may be placed. In spite of this, the unit can utilize known technology and known materials. The unit can also comprise a modular system for several units and can be arranged with a common storage box for these.
