Abstract

The invention relates to a retaining device for retaining very small medical tools, comprising a main body (1) having a top side (2) and a bottom side (3). The retaining device is characterized in that at least one opening (4) for at least part of at least one dental tool is formed in the main body (1). The at least one opening extends from the top side (2) to the bottom side (3) and is surrounded by a sleeve (5), in which at least one retaining element (6) is integrated.

Description

The invention relates to a holding device for holding small medical tools, in particular drill bits for dental drills, screw wrench heads for inserting and securing implants and the like.

Small medical tool holders are used to give the user quick and accurate access to the instruments.

Commercially available holders usually consist of a plate on which recesses or other holding elements are mounted, in which the tools are inserted, inserted or clamped.

A holder for dental tools is known for example from the patent CH631341. It describes a container with various removable and sterilizable inserts having different sized holes for insertion of medical tools. A disadvantage of this holder is that for securely fixing the tools of the diameter of

Holes must be adapted to the shape of the tools to be used. This has the consequence that the various tools can only be used in the openings provided for this purpose. Tools whose diameter

For example, is significantly smaller than that of the hole are not or only insufficiently fixed in the hole and can therefore easily fall out during transport.

From the patent US 8074799 B2 a holding device for holding and sterilizing dental tools is also known. The holder comprises a base body made of a hard material into which holding elements made of an elastic material can be inserted. The Halteeiemente have in the middle of an opening into which, for example, drill bits are inserted and thereby fixed. The elastic elements are designed to be removable from the base body, so that holding element and body can be sterilized separately from each other. A disadvantage of this holding device is that the holding elements have to be taken out individually for sterilization and then reused, which is associated with additional expense. By removing and reinserting the retaining elements are also mechanically loaded, which can cause damage to the holding elements. In addition, during sterilization, in particular during steam sterilization, further impairments of the elastic material may occur. Another disadvantage of this holder is that the transition between body and

Retaining element is never completely sterile.

A further device for holding drilling attachments is known from US 3248167 A. The device disclosed therein comprises a plate at the top of which a plurality of wells for inserting the drill heads are mounted. The underside of the device is provided with a magnetic plate, through which the drill heads are additionally fixed. The magnet can turn the device upside down in a sterilization container and immerse the drill heads in a sterilizing fluid without the drill heads falling out of the wells. A disadvantage of this device is that the magnet must extend over the entire base area so that all depressions are detected. Therefore, relatively large or strong magnets are needed.

The object of the present invention is now to overcome the disadvantages of the prior art and to provide holding devices with improved properties.

The object is achieved by a holding device for holding medical micro tools, which has a base body with a top and a bottom and is characterized in that in the base body at least one recess for at least a part of at least one dental

Micro-tool is formed, which extends from the top to the bottom and is surrounded by a sleeve in which at least one retaining element is integrated. As a sleeve surrounding the recess material is called. The sleeve thus represents a substantially tubular and hollow body inside with a closed lateral surface.

The recess is according to the invention an opening which extends from the top to the bottom of the body and is intended to, the

At least partially accommodate the smallest tool. The invention is characterized characterized in that the sleeve comprises a holding element which fixes the tool in the recess.

The basic body is preferably a plate. This may be small

Dimensions have. For example, the width of the basic body in the range of 120 to 160mm, preferably at 140mm, and the depth in the range of 50 to 90 mm, preferably 70mm, lie. The entire height of the

Holding device may for example be 30mm, preferably 25mm and more preferably 20mm. If, as will be described later, a cover is provided, it may again have a height of, for example, 25 mm, preferably 20 mm and more preferably 18 mm.

Under a miniature dental tool, which is also referred to below simply as a tool, for example, drill bits or drill bits, drilling adapter or wrench or

Wrench attachments, such as Phillips, hexagon or Allen key, understood that are used by oral surgeons or dentists. The Haiteelement, for example, represent a flexible clamping element which protrudes in the radial direction of the sleeve into the recess and clamps the tool when inserted into the recess between the clamping element and sleeve or exclusively between clamping elements. As a result of the holding element according to the invention, the opening no longer has to be adapted exactly to the size or the shape of the tool to be hardened, and may therefore also be larger, since the tool is held at least by the holding element. In contrast to adhesive devices without Haiteelement therefore tools can be kept, which are significantly smaller than the recess or which do not protrude into the recess,

for example, have no shaft. This can be a reliable

Cleaning, in particular sterilizing the tools are ensured.

Preferred is an embodiment in which at least one Haiteelement

at least one magnet is. The magnet or magnets are according to the invention in the Sleeve integrated, that is, they are at least partially surrounded by the material which surrounds the recess and the sleeve.

For example, several magnets may be distributed in the sleeve. However, the sleeve can also contain only one magnet, which surrounds the recess in a circle and thus forms a closed ring around the recess.

According to the invention, it is also possible that the entire sleeve of a

Magnet exists The magnet can thereby enclose the recess directly, so that the entire inner circumferential surface of the recess is limited by the magnet. However, the annular magnet may also be embedded in another material such that the inner side of the recess and magnet have no points of contact. In this case, the magnet or magnets is completely surrounded by the material of the sleeve.

Magnets have the advantage that metallic tools, for example screw attachments, drilling attachments, drilling adapters, tweezers, etc., additionally or alternatively to the purely mechanical fixation on the recess, on the inner wall of the sleeve and / or possibly on the upper side of the sleeve in be held close to the recess. This is an exact adaptation of

Recess to the shape or size of the tool is no longer mandatory. Thus, for example, even very narrow tools can be securely fixed. In contrast to retaining elements with a purely mechanical function, a magnet also has the advantage that the magnet can be arranged inside the sleeve, that is to say surrounded by the material of the sleeve, and mechanical wear is ruled out.

In addition, by integrating the retaining element, in particular the

Magnets are used in the material of the sleeve of the advantage that the magnet does not have to protrude beyond the material of the sleeve, in particular into the recess. As a result, the sleeve can also have a continuous surface in the recess and can therefore be reliably cleaned and, in particular, sterilized. In particular, gaps are avoided.

Another advantage of the holding device according to the invention is that by the magnet falling through of the tool in the recess is prevented. Thus, even short tools can be fixed so that they project beyond the upper edge of the recess, although otherwise they would sink into the recess due to their length. An annular arrangement of magnets around the recess also has the advantage that, in contrast to holders, as described in US 3248167 A, a smaller amount of magnetic or magnetizable material is needed, since this is only on the sides which the tools are fixed. Thus, the weight of the holding device is reduced and the handling of the holding device thus simplified.

The recess can pass through the underside of the base body, so that the top and bottom are connected by the recess. In the simplest form form the top and bottom of the body a substantially flat surface. However, the sleeve may also extend beyond the bottom, that is, the sleeve extends beyond the underside of the base and forms a tubular extension. Such an elongate sleeve is particularly advantageous for long tools, because they are better held and a wobbling in the recess is more avoided.

In an advantageous embodiment of the invention, the base body with the sleeves is designed in one piece. Under a one-piece design is understood that the base body and the sleeves in which the receptacles are formed, either made of only one molded part, or that all components of the holding device, in particular the body and the sleeves firmly, that is undetachably connected to each other are. This has the advantage that for sterilizing the holding device, the {components are not taken apart and

then reassembled. However, a significant advantage of the one-piece embodiment is in particular that thereby

Contact points and spaces, such as gaps between the components are avoided. Such interfaces are a preferred breeding ground for germs and are difficult to disinfect. A holding device with a one-piece mold, on the other hand, has the advantage that it is easy to sterilize. A one-piece mold is also easy and inexpensive to produce, for example, it can be produced by injection molding of plastic or aluminum. The holding device preferably has a plurality of recesses, wherein the recesses may be shaped differently. The different shape of the recess can be adapted to the shape of the tool to be used, whereby the maintenance of the tools in the device is further improved.

In one embodiment of the invention, the sleeve is a different component from the main body. The base body and sleeves can then be formed, for example, of different materials and / or have different colors. Different colors allow faster mapping of different tools, especially if they are similar to each other.

The sleeve may be detachably or detachably connected to the base body. Removable sleeves have the advantage that individual sleeves can be selectively replaced if they have been damaged without the entire holding device must be replaced. Removable sleeves are also advantageous if the base body only a few recesses are provided, but a variety of different tools is needed. The user can then selectively use the sleeves with the corresponding recesses, which are each adapted to the shape of the corresponding tool, and these

if necessary, replace it with other sleeves if you need another tool at a later time.

Preferably, however, the sleeve is firmly connected to the base body, for example by gluing or spraying or injection. As already described, a one-piece construction has the advantage of a better one

Handling with a better sterilizability. The sleeve forms an integral part of the body. In this case, the sleeve, which consists of the same material as the base body, represent the area of the base body around the recess. Alternatively, however, it is also possible, as described, for the sleeve initially to be present as a separate part and subsequently to be connected to the base body or for the base body to be formed around the sleeve. In the latter two cases, the material of the sleeve may correspond to that of the main body or be another material. Also preferred is an embodiment in which the sleeve has an enlarged head portion. This one typically has a larger diameter than the diameter of one provided in the main body for the sleeve

Passage, so that the head portion on the one hand prevents slippage of the sleeve through the aperture and on the other hand ensures a more stable hold of the sleeve by increasing the contact surface of the sleeve on the body.

The sleeve according to the present invention, for example, a

Have diameter of 12mm, with a recording of, for example, 6.5mm is formed in this. If an extended head area is provided, its diameter can be, for example, 16.5 mm. The height of the sleeve can be 13.5mm in one example. The invention is not limited to the dimensions given. However, in the case of a separate sleeve, the dimensions should be selected such that a sufficient material thickness of the sleeve is ensured, which permits introduction into the basic body without deformation of the basic body. In addition, in the head area, the material thickness to be chosen so large that a

Magnetic ring can be included. The outer diameter of the magnetic ring can be for example 12mm.

To improve the hold of the sleeves in the body even further, the

Base body on the upper side preferably be provided with at least one recess which is adapted to the shape of the underside of the enlarged head portion of the sleeve, that is, the recess on the base body forms a negative mold to the underside of the enlarged head portion. When inserting the sleeve into the base body, in particular into a passage of the base body, the contact surface between the depression and the head region is thereby maximized, as a result of which an accurately fitting positioning of the sleeve on the base body is achieved. The depression on the main body can only in the top of the

Basic body be provided. However, it is also possible and preferred that this also shows in the bottom of the body. For example, with a constant material thickness of the base body, a trough-shaped depression can be formed.

In a particularly preferred embodiment, the sleeve at the

Upper side, in particular on an optionally provided extended head portion of the sleeve, indentations. The indentations can also be referred to as notches. With the help of the indentations, the sleeve can additionally be fixed to the body and slipping the sleeve on the

Holding device can be prevented. This can be done by additional

Fixing elements can be achieved, which are attached to the top of the body and can engage in the recesses. Preferably, however, the indentations in connecting or integrating the necks in the

Body filled with material. For example, glue can be used in these

Indentations are introduced. But are particularly preferred in the production of the body, the indentations with the material of

Filled body, that is, this injected with the material. This prevents unwanted twisting or slipping of the sleeve in the body. In the connected state, the indentations of the sleeve

preferably completely filled, so that the upper side of the Haitevorrichtung represents a continuous surface without columns in the region of the indentations.

According to a further embodiment, the holding device has a lid, which is detachably connected to the main body of the holding device. The lid preferably has an inverted trough shape, that is, is open at the bottom. Thus, the lid can be applied to the body and between the lid and the body, a cavity is formed. In this cavity are in the closed state of the holding device, at least the heads of the tools, which are held in the receptacles. The cover is preferably connected via a clamping connection with the base body. Here, for example, the lower edge of the lid can be jammed with the outside of the body. In this embodiment, the dimensions of the Deckenis are slightly smaller than the outer dimension of the body. Preferably, however, at least one inwardly directed clamping element is provided on the lid on the tub bottom of the lid. This clamping element, for example, a clamping sleeve or a

Represent clamping cylinder. The clamping element engages with a clamping opening in the base body.

According to a preferred embodiment, at least one annular elevation is provided on the inside of the lid bottom, which extends into the interior of the lid. The annular elevation is preferably designed in one piece with the lid. The annular increase is an upper bracket for Tools created. The annular elevation is therefore provided on the lid so that it is aligned in the closed state of the holding device with at least one recess in the base body. In particular, the annular elevation is coaxial with at least one recess of the

Body. By the annular increase, which is directed in the closed state of the holding device down, thus a tool held on the recess is fixed from above and in particular prevents slipping. With this embodiment of the holding device, it is also possible to hold and clean tools that have no shank and therefore not in the

Recess can protrude into the body. Such tools are, for example, drilling adapters.

According to a further embodiment, an annular recess is formed in the upper side of at least one sleeve. The recess is coaxial with the axis of the recess. Through this depression, a step is created in the top of the sleeve near the recess. The step serves to fix the head of tools which are received in the recess. In addition, the stage is used in tools that have no shank and therefore can not engage in the recess to a lower fixation, which ensures a reliable grip of the tool together with an annular increase on the lid.

A further preferred embodiment of the invention is that the holding device at the top of a clamping device for fixing

Has tools on the body. This can for example consist of two vertically projecting from the top webs, which are arranged parallel to each other. The element to be fixed, for example a ratchet or a dental drill, is pressed between the two webs and clamped between the two webs, so that the object at the top of the

Main body is fixed. The clamping device can also represent a locking device. For this purpose, the webs, for example, at their the top of the

Basic body ends inclined to each have a curvature, so that they form a trough with a convex shape into which the object to be fixed snaps when pushing in With the device according to the invention can for example fix drill and drill heads safely and easily to the fixture and possibly transport.

Identical components are provided in the figures with the same reference numerals and their structure and function will optionally only be explained once.

1 shows an embodiment of the holding device according to the invention is shown, in which the main body 1 is designed in one piece, that is, the base body and the sleeve are formed of a material and the sleeves 5 are integral parts or areas of the base body 1. Das Rectangular basic body. 1 has an upper side 2, which are provided with cylindrical recesses 4, which in the illustrated embodiment, the bottom 3 break. In Figru 1, eight recesses 4 are shown. The material surrounding the recesses 4 forms the sleeve 5. In the embodiment according to FIG. 1, an annular groove 51 is formed around the recess 4 in the upper side of the sleeve 5

brought in. In this groove 51, an annular magnet (see Figure 3) as

Holding element 6 inserted for fixing tools in the recess 4 become. In the middle of the holding device is a locking device 8 of two vertically projecting from the top and parallel to each other

arranged webs 9, in which, for example, a pin, a ratchet or a drill can be clamped.

The underside of the holding device 1 shown in FIG. 1 is shown in FIG. The recesses 4, break through the bottom 3 of the body 1 and thereby form a through opening. The sleeves 5 with the

Recesses 4 also extend down over the bottom 3.

As can be seen from Figure 3, in one embodiment of the

Holding device according to Figures 1 and 2, an annular magnet 6 are inserted into the annular groove 51 in the top of the sleeve 6. On this magnet 6, a cover ring 13 is then applied, so that the magnet 6 is surrounded by the material of the sleeve 5 and upwardly of the material of the cover ring 13. The cover ring 13 and possibly also the magnet 6 can be glued to the sleeve 5. In the thus created holding device then a tool W through the opening of the cover 13 and the opening of the magnet 6 and through the recess 4 are performed. In the illustrated embodiment, the tool is a screw cap having a shaft portion and a

Head portion having a larger diameter than the shaft portion. As a result, the tool W in the recess 4 is held on the one hand by the magnetic force of the magnet 6, which acts on the shaft portion and the other by resting the underside of the head portion on the cover ring 13 and the magnetic force of the magnet 6 acting there.

FIG. 4 shows the perspective view of a further embodiment of the holding device according to the invention. In this embodiment, deviating from the first embodiment according to Figures 1 and 2, the sleeves 5 are formed as separate components and connected to the base body 1. A sleeve 5 is shown separately in FIG. As can be seen from this view, the sleeve 5 has an enlarged head portion 11. in this head portion 11, an annular magnet 6 is accommodated so that it is adjacent to the inside of the sleeve 5, that is, the recess 4, to this recess. However, the magnet 6 can also be accommodated in the sleeve 5, that this is not up to the inner

Diameter of the sleeve 5 is sufficient and thus not applied to the recess 4, but also covered on this page by the material of the sleeve 5. At the top, the magnet 6 is covered by the material of the sleeve 5. In the top of the extended head portion 11 indentations 7 are introduced. These are so deep in the illustrated embodiment that the magnet 6 contained in the head region 11 is exposed to in the region of the indentations. But the indentations 7 can also have a smaller depth. In addition, 5 indentations 7 may be provided according to the invention in the lower part of the sleeve 5, in particular at the lower end of the sleeve. As can be seen from the finished state of the adhesive device in Figure 4, the indentations 7 are filled with the material of the base body 1. This region of the main body 1, which may also be referred to as a fixing region 10, is preferably produced in the production of the main body 1. In particular, the sleeves 5 can be placed in a mold or matrix for injection molding so that they are later arranged at the desired locations in the base body 1. During the injection molding and the indentations 7 of the sleeve 5 are filled with the material of the Grundköpers 1, which may be, for example, plastic filled and so the fixing regions 10. However, it is also possible to produce the fixing regions 10 only after the production of the main body 1. Here, the sleeves 5 can be introduced into passages of the base body 1 and then the indentations 10 are sprayed with material that connects to the material of the base body 1.

Although the sleeves 5 protrude beyond the upper side 2 of the main body 1 in the illustrated embodiment, it is also within the scope of the invention that the upper side of the sleeves 5 is flush with the upper side of the main body. In addition, it is also possible and preferred that in the sleeve 5 in the top around the

Recess 4 is a concentric annular recess is introduced (not shown). Through such a depression, a step is introduced around the recess 4, by means of which at least the head region of tools W can be fixed.

As in the first embodiment, a locking device 8, which is formed from two upstanding webs 9, is also provided in the middle of the main body 1 in the second embodiment. In addition, the second one

Embodiment of Figure 4 on the circumference of the body 1 after a downwardly extending edge 100. Thanks to this edge 100, the

Holding device, for example, be placed on a table or treatment tray, without that down over the sleeves 5 protruding tool is pushed upwards. Finally, in the second embodiment mounting holes for the attachment of a lid 14 (see Figure 5) are provided in the base body 1.

As is apparent from the sectional view of the second embodiment in Figure 5, 14 clamping cylinder 140 are provided on the lid, which in the

Fixing holes can engage in the base body 1 and thereby connect the lid 14 with the base body 1. In addition, the

Cut view that the main body 1 has a substantially flat plate shape, but in the areas around the sleeves 5 trough-shaped depressions 12 has. The sleeves 5 each have an extended

Head portion 11, which rests on the recess 12 provided for this purpose.

Tools that are included in this fixture can thus be reliably held and transported. In addition, one can

Sterilization, in particular a steam sterilization of the tools are performed while they are held in the holding device and the

Holding device 1 is closed by the lid 14

FIG. 6 shows a schematic representation of an embodiment of a blanket 14. As is apparent from this figure 6, the lid 14 has a

Trough shape on. From the tub bottom 141, the side walls 142 of the lid 14 extend vertically downwards. In addition, Kiemmhüisen 140 are provided on the inside of the lid, which also extend downwards. In two corner regions are on the trough bottom 141 of the lid 14 annular

Increases 143 provided. These also extend downwards. As can be seen from FIG. 5, the annular elevations 143 project downward from the bottom of the tray 141 in such a way that, in the closed state of the holding device, they are in the vicinity of the upper side of the sleeve 5 in the

Get body 1. By means of the annular elevations 143, tools can thus be fixed between the base body 1 and the cover 14.

In particular, this can also be reliably held tools that have no shaft and thus do not protrude into the recess 4 of the base body 1.

To clean the tools, these are preferably first cleaned manually and then inserted into the holding device. The so with

Tools equipped holding device, preferably closed with the lid, is then fed to an autoclave for performing the actual sterilization process. For this purpose, if appropriate, the holding device can be previously introduced into a casing or a bag. In the autoclave, the holding device is then heated, thereby sterilizing the tools. If a sheath or a bag is provided, it preferably closes when heated, so that subsequently a contamination of the tools is no longer to be feared. After sterilization, the sheath device with lid and the tools held therein, preferably in the sheath or pouch, may be provided for the treatment of the patient. Immediately prior to treatment of the patient, the package in the form of the envelope or bag may then be opened.
