Description

The present invention relates to a work-end packaging unit, in particular a sterile packaging unit, for a medical-technical working end, with an outer packaging forming a receiving space for the working end, a holding device arranged in a certain position in the receiving space and separate from the outer packaging and a position in the holding device held working end, wherein the holding device is designed to space the working end at least partially, in particular in the region of an operative portion of the working end of the outer packaging. For example, tools such as scalpels, tips, cutters, saw blades, ultrasonic blades, RF probes, etc. are to be understood as working ends in the context of the present invention.

For packaging and handling of medical devices before and after their use, different packaging and devices are known. Packaging of medical-technical work ends with sharp and / or sharp active sections, for example in the form of cutting or sawing edges, milling heads and drills, are subject to special requirements. Because in addition to the protection of the packaged work from unwanted effects such as dirt and damage also a protection of users from injury before and especially after use of the working end must be ensured.

For this purpose, different solutions are known from the prior art, for example in the form of a blister pack with a clamp in the coupling region of a tool in order to position and hold it in a defined position in the packaging. A disadvantage of such blister packs is that they can be damaged by contact with the tool. Another disadvantage is that, if it comes by external action on the blister pack associated with their relatively low stability to a release of the clamping of the tool therein, the tool can slip in the package and in particular with its sharp knurled edges can hit the packaging. As already in the DE 10 2013 004 168 A1 As a result, microfine particles of the packaging can undesirably reach the region of the cutting edges of the tool and from there may be introduced into an operation wound, which can lead to serious tissue irritation.

To improve these circumstances, the DE 10 2013 004168 A1 a package of sterile surgical tools, in which the surgical tool is packaged in a plastic package under sterile conditions, wherein the package is at least two parts and consists of an inner protective packaging for sensitive parts of the surgical tool and a protective packaging receiving, sealable blister pack. In addition, a method for packaging sterile surgical tools is proposed in which the surgical tool is packaged under sterile conditions in the plastic packaging, wherein in a first step, first the surgical tool is at least partially and in particular packed with its sensitive cutting edges and work surfaces in the first protective packaging and the Protective packaging is spent together with the surgical tool packaged there in a second blister pack, there is secured in place and is then sealed with a sealing film.

Another known solution for a packaging for rotating tools provides a slide box together with an outer packaging in a peel bag. In this solution, however, has the disadvantage that the thrust box is formed with the outer packaging is relatively large (the ratio of the packaging size to the product size is much too large).

Another disadvantage of known packages is that the medical tools packaged therein are unprotected after removal of the package prior to use, for example, when provided on an instrumentation table for the surgeon shortly before use in an operation. Closely associated with this is the disadvantage that the packaged tools are either already sterile and can only be removed from the packaging shortly before use in order not to endanger the sterility or, after unpacking, first have to be sterilized using additional aids, which the Danger of a negative impact on the sharp knit structures such as cutting etc. entails, as they are completely free and unprotected at the unpacked tool.

Furthermore, in the case of known packaging, there may be the disadvantage that there is thus a danger of infection for the personnel when handling or disposing of used, contaminated working ends.

Against this background, the object of the present invention is to reduce the stated disadvantages of the prior art, in particular to provide a working end packaging unit with a medical working end, which ensures a stable and secure holding of the working end in the packaging during a Storage and transport, so in the packed condition, ensures. In addition, the packaging unit should facilitate the provision and use of the working end in the operating room and allow a safe and safe disposal of the working end after use. In particular, in surgical work / tools, the packaging unit should be user-friendly and allow easy, safe and quick handling of the working end before, during and after the operation. Finally, a possibility should be created to be able to sterilize an unpacked working end, if necessary, without risking damage to its active edges.

This object is achieved according to the present invention by a work-end packaging unit, hereinafter simply referred to as packaging, according to claim 1, that is, a packaging, in particular sterile packaging, for / with a medical (s) working end, with a receiving space for the Working end forming outer packaging, a positionally arranged in the receiving space and the packaging separately held holding device and a positionally determined holding in the holding work, wherein the holding device is formed, the working end at least partially, preferably completely, in particular in the region of an active portion of the working end of the outer packaging to space. According to the invention, it is provided that the holding device leaves at least the active portion of the working end freely exposed in the receiving space.

In the context of the invention, the working end may in particular be a working end / surgical work end with a distal active section for fulfilling an operative function and a proximal coupling section for coupling the working end, for example with a handle unit, in particular a drive handle unit. Examples of such working are mainly rotating working and sawing work, including drills, cutters, saws, screw tops, cutting blades or sanding attachments that are coupled in a well-known manner with a handle and / or drive unit. Under the effective portion of the working end are in the context of the invention usually sharp and sensitive active or working contours to understand, for example, sharp edges, blades, drilling, sawing and milling contours. According to the invention, at least the active portion of the working end is exposed in the holding device and has neither direct contact with the holding device nor for repackaging. In other words, the holding device is open at least in the region of the working portion of the working end. As a result, inter alia, the advantage is achieved that the effective portion for a user is almost fully visible, which facilitates identification of the working end. In addition, the active section for media such as disinfecting and sterilizing agent is freely accessible. This has the great advantage that the packaging according to the invention is suitable both for sterilized and unsterilized working ends. The latter can be taken out of the outer packaging and sterilized in a particularly advantageous manner together with the holding device.

According to the invention, the holding device is formed separately from the outer packaging. Therefore, held in the holding device working end can be removed together with this from the outer packaging and in particular remain after unpacking in the holding device. Preferably, the packaging and the holding device is designed such that removal from the outer packaging by handling the holding device and without direct contact of the working end can be done so that the probability of contamination of the working end easily and safely minimized, if not avoided. In addition, the working end can be removed with the holding device from the package and placed on an instrument table, without having to put it loose. During an operation or treatment, the holder can be used in a particularly advantageous manner for intermediate storage of the working end, resulting in better order and clarity.

Since at least the active portion, preferably the entire working end, is spaced from the outer packaging, a contact-free mounting of the working end in the region of the active portion and any existing cutting or sharp edges can be ensured with particular advantage. In particular, it is not possible for the kneading section to contact all the surrounding packaging components such as, for example, blisters, Tyvek film, carriers, etc. Unwanted mutual interference of outer packaging and working end, such as material removal or perforation of the outer packaging or blunting or contamination of the working end can be reliably prevented.

Overall, the invention thus in addition to the packaging in the true sense by the separate holding device an independent working end holder available, in addition to a safe and stable storage of working during transport in the respective outer packaging also a way to defined positioning and safe handling of the working in the frame reprocessing (eg sterilization) and provision during treatment in the operating room. For this purpose, the holding device together with the held therein End of work to be taken out of the outer packaging and placed.

Locations "proximal" and "distal" used in the description of the invention are related to the working area of the instrument and its operator. In this sense, distal means "away from the operator" while proximal means "near the operator".

Advantageous embodiments of the invention are claimed in the subclaims and are explained in more detail below.

An embodiment of the invention is characterized in that the receiving space is formed closed by the outer packaging, in particular hermetically sealed. He may also be sterile. By the invention and the working end of the outer packaging spaced holding fixture, the sterility and integrity of the outer packaging can be ensured in a simple and reliable manner.

According to one embodiment of the invention, the holding device has a base plate. This can in particular be designed such that it forms a footprint for positionally stable installation of the holding device with a working end held therein, in particular in a state unwrapped from the outer packaging, and / or an investment structure for abutment with the outer packaging. In addition to the standing surface, the holding device can have further abutment structures or sections which interact with the outer packaging and abut it, so that a clear and stable positional positioning in the receptacle of the outer packaging is ensured.

The holding device may according to an embodiment of the invention comprise at least two spaced apart support structures for positionally determined positioning of the working end. Preferably, these are each arranged on the base plate and can extend from this into the receiving space. In addition to the function of holding the working end, the holding structures can form systems with which the holding device rests against the outer packaging, preferably in such a way that it is secured in position or fixed in position in the receptacle of the outer packaging.

An embodiment is characterized in that one of the holding structures is arranged on the end side on the holding device, in particular on the base plate. Another of the support structures may be arranged substantially centrally on the holding device, in particular on the base plate. This allows a particularly stable mounting of the working end in the holding device.

The other of the support structures may be configured for positionally positioning the working end relative to the fixture in a second direction and a third direction, the first, second and third directions being orthogonal to each other. By such a guide the working end is held on the one hand stable in the holding device, on the other hand, it can be particularly easily arranged by a user in the holding device and removed from the holding device.

It is particularly advantageous if, according to a further embodiment of the packaging, at least one of the holding structures forms a positive connection and / or a frictional connection with the working end, in particular with a coupling structure of the working end.

At least one of the support structures, in particular both support structures, may each have two mutually opposite support arms. Between these, a slot for receiving and holding the working end is formed in each case. The retaining arms may be arranged substantially perpendicular to the base plate of the holding device. They may be formed in a particularly advantageous manner as clamping arms and in particular in a direction transverse to the slot having resilient properties. Removal and placement of the working end in the support structures is particularly easy if, according to one form of the invention, the slit expands from proximal to the base in the direction distal to the base. This favors a largely safe handling of both unused and used instruments, so that in particular an injury-free disposal of products in the holder improves and thereby basically existing risk of infection is reduced.

According to a development of the invention, the slots facing sides of the support arms may be provided with indentations. Such indentation can advantageously form detent bays for the working end inserted into the slot, so that it is held securely and yet easily removable for the user in the holding structures.

A particularly user-friendly, as injuries to a user on the avoiding in the holding device embodiment of the invention provides that the holding device has a protective tab which protrudes from the base plate in the receiving space and covering a distal end of the working contact without contact. This way is a User protected when handling the holding device with the work held therein from injury by possibly sharp edges of the working end.

According to one embodiment of the invention, the outer packaging is formed as a blister. Such blisters are cheap and can be made for almost any forms of working end and / or holding device. Preferably, the blister pack may have a lower shell with a recess forming the receiving space for the working end. Such a lower shell can be designed simply with sufficient stability and shape for positionally stable positioning of the holding device and working end. By means of a cover film arranged in a known manner on the lower shell, the receiving space can be closed in the desired manner, in particular hermetically and / or aseptically.

According to a further embodiment of the invention, the packaging may have a carrier element, for example in the manner of a strainer basket. This can be arranged in the outer packaging together with the holding device and the working end held thereon, in particular with a plurality of holding devices with the respective working end held thereon. By means of such a carrier element more holding device with working ends can be handled very easily and simultaneously, for example, supplied to a sterilization and / or placed on an instrumentation table.

According to a further embodiment of the invention, the holding device can be coded, for example by being colored. In this way, with the invention, a system can be provided particularly simple, with which not only different working ends for a user can be easily distinguishable encoded, but also such coding or identification of certain working even after unpacking the working end of the outer packaging of the respective Can be maintained assigned to the end of the work. In particular, working ends that have already been unpacked and located for use on an instrumentation table or in a sterilization device are particularly easy and safe for the user to recognize. An identification of different working ends and / or holding device can preferably take place via different colors of the holding devices, for example with regard to their indication or to certain working groups, etc. In this way, incorrect combinations of products by the color of the particular formed as a plastic injection molded part holding device in and outside of Outer packaging should be avoided.

According to a further embodiment of the invention, the holding device may be formed as a plastic molding. If it is designed according to a development of the invention as a multi-component injection molding, it may for example be provided with a particularly non-slip base. This allows a stable arrangement of the holding device on an instrumentation table and / or a carrier element such as a screen basket during a treatment process. In addition, so the handling of the holding device when removing the unused working end as well as in the introduction of the used end of work can be immensely easier.
