Definitions

  • the invention relates to a device for holding an implant, an osteosynthesis part, an associated structural part or an instrument by means of a manipulation element. Screws, pins and
  • the osteosynthesis parts also include plates, for example from the maxillofacial area. Abutments and prosthetic abutments are worn under abutment parts. Simplified, all of these parts - including the instruments to be held - are initially only referred to as implants. Manipulators are implantation tools, means of transport and instruments for holding.
  • the invention is applicable in the production of the implants, for their provision before the surgical operation and immediately during the operation.
  • the main field of application of the invention is where the implants, e.g. due to the need for sterile working methods, at least not directly by hand, and where it is important to hold the implants securely, but also to release them quickly - without additional tools.
  • a specific example of the use of the invention is an ampoule for transporting and storing an implant, in particular a dental implant, which is intended to be inserted, for example screwed, into a receiving bore prepared in the bone.
  • the location hole. can be a threaded hole or the implant has a self-tapping thread.
  • the implant can be removed from the ampoule during the surgical operation under sterile conditions with an attached tool and then inserted into the receiving bore in the bone with this tool.
  • the ampoule can preferably be opened by removing a closure lid. To ensure sterile operation, it is customary to store the ampoule in a secondary capsule until the start of the operation.
  • the implant stored in the ampoule is connected to the cover, which acts directly or indirectly at the same time as a screwing tool and is used at least for a rough insertion of the implant.
  • the lid in in the simplest form, an extension with a non-rotationally symmetrical engagement contour, which interacts with a complementary contour on the implant head. From US-A-5 312 254 and US-A-5 538 428 it is known to insert a connecting element between the cover and the implant which transmits the rotating screwing-in movement.
  • US-A-5 062 800 discloses an ampoule where the lid is the connecting element to the screwing tool. These ampoules are sometimes quite complex, with the tool components generally being used only once. Often, a relatively large number of manipulations are required to handle these ampoules, and external screwing tools are also required. Finally, it is questionable whether the implants are held sufficiently securely by the screw caps or the connecting elements.
  • EP-B-0 231 730 discloses a simple variant, where the implant is in a sleeve, the implant head projects beyond a sleeve end and closes it. The sleeve is melted into a glass ampoule with constrictions and an internal spring. The implant head is supported against the spring and the sleeve is fixed within the constrictions, a constriction at least partially closing the base of the sleeve.
  • Appropriate external tools are used to grasp the implant, no means being provided on the ampoule to make removal of the implant from the ampoule and transporting it to the site of the implantation easier and safer.
  • Such a type of ampoule with sterile conditions is also described in the monograph by SCHROEDER / SUTTER / BUSER / KREKELER: Oral Implantology, Georg Thieme Verlag Stuttgart and New York, 2nd edition, 1996, pp. 219-221.
  • the capsule-shaped ampoule has a removable lid and an intermediate wall that extends perpendicular to the longitudinal axis near the lid.
  • this intermediate wall there is an axial passage in which a bearing ring sits, in which the head of the implant is inserted, while the apical part of the implant protrudes into the ampoule.
  • a blind hole-shaped, axial threaded hole in the implant head In order to grasp the implant, a lockable insertion tool is used, the mandrel of which is screwed into the threaded hole of the implant. Screwed onto the insertion tool, the implant is now pulled out of the ampoule. The implant is then inserted into the hole in the bone, using keys on the insertion tool. Finally the counter between the implant and the insertion tool has to be loosened again so that the insertion tool can be removed.
  • This handling requires numerous work steps, a multi-part set of instruments and special mindfulness and skill of the surgeon.
  • the invention is based on the problem of perfecting such devices. It is important here that the connection between the implant and the manipulator when gripping the implant is fast, secure and without to design additional tools. At the same time, the subsequent release, ie letting go of the implant when the manipulator and implant are separated, must also be possible in a simple manner. For processes with increased purity or sterility requirements, the respective conditions with the device to be created must be observed. Particularly in the preparatory phase of the surgical operation and during the operation, it must be ensured that the implants and components of the device used are always guided safely and do not come loose in an uncontrolled manner.
  • the task is to further develop the ampoule in such a way that the contamination-free removal of the implant from the ampoule with the inserted insertion tool, the screwing in of the implant and the final separation of the insertion tool from the implant are considerably simplified.
  • the ampoule to be proposed must meet all the requirements regarding sterility and safe handling.
  • the ampoule must be able to be manufactured as a disposable item with the already integrated holding device in a cost-effective manner.
  • the task is also to be solved in connection with a container or a bare base from or from which the implant is to be transferred.
  • the device for holding an implant consists of an adapter sleeve and a manipulator, the
  • Adapter sleeve for the temporary connection between the plantation and the manipulator is provided.
  • One end of the adapter sleeve is releasably attached to a plug-in attachment of the positioned implant; the tip of the manipulator can be releasably attached to the other end of the adapter sleeve.
  • the implant was gripped by attaching the manipulator to the adapter sleeve already connected to the implant.
  • the implant can now be transferred from the previous position to a new position as a double plug connection between the implant, adapter sleeve and manipulator.
  • the implant can be transferred from one work station to the next or removed from a storage space or from a container and brought to the intended place of use - this could be the implantation site on the patient.
  • the manipulator is then designed as a screw-in tool and the rotary movement of the screw-in tool is transmitted to the implant by engaging a non-rotationally symmetrical contour at the tip of the screw-in tool with a complementary non-rotationally symmetrical contour arranged on the implant .
  • the plug connection between the implant and the manipulating member is released, while the adapter sleeve remains attached to the tip of the manipulating member.
  • a lower release force is required than for Disconnect the more intensive connector between the adapter sleeve and the manipulator.
  • the adapter sleeve can be removed separately from the manipulation element with the appropriate effort.
  • the adapter sleeve is placed on the plug-in attachment of the implant, while the tip of the manipulation element can be inserted into the second plug-in end of the adapter sleeve.
  • the device is designed as follows.
  • the adapter sleeve serves for the connection between the implant head and the implantation tool - for example a screwing tool - during the removal of the implant from the ampoule and the insertion of the implant with the manipulation organ designed as a tool.
  • One end of the adapter sleeve is releasably attached to the head of the implant fixed in the ampoule and encompasses the implant head; the tip of the tool can be releasably attached to the other end of the adapter sleeve.
  • the implant can be removed from the Pull out the ampoule, transfer it to the prepared borehole in the bone and insert it.
  • the rotary movement of the tool is transferred to the implant by not having the non-rotationally symmetrical contour at the tip of the screwing tool with the complementary one arranged on the implant head rotationally symmetrical contour is engaged.
  • the implant ends at the top with an external polygon, and the insertion tool has an internal polygon to complement it.
  • the plug connection between the implant and the tool is released, but the adapter sleeve remains attached to the tip of the tool, since the plug connection that can be released with less effort separates the adapter sleeve and the plug approach on the implant rather than the firmer, more difficult to detach plug connection between the adapter sleeve and the tool.
  • the adapter sleeve encloses the implant head and is - in the ampoule holding the implant - extendable in a seat of the ampoule housing, ie the adapter sleeve is already an integral part of the ampoule supplied. After opening the housing, for example by removing a cover, and removing an additional fixing pin as an option, the tip of the tool can be connected to the second plug end of the adapter sleeve.

Abstract

Le dispositif proposé, conçu comme organe de préhension d'un implant (1), comprend une douille adaptatrice (300) et un organe de manipulation, la douille-adaptatrice (300) étant prévue pour effectuer une connexion temporaire entre l'implant (1) et l'organe de manipulation. La première extrémité de la douille adaptatrice (300) est embrochée amovible sur une saillie enfichable (10) de l'implant (1) mis en place; et la seconde extrémité de la douille adaptatrice (300) est embrochée amovible sur la pointe de l'organe de manipulation. Une fois que l'organe de manipulation est mis en place sur la douille adaptatrice déjà associée à l'implant (300), on peut considérer que l'implant est pris (1) grâce à une double connexion entre l'implant (1), la douille adaptatrice (300) et l'organe de manipulation, d'où la possibilité de transférer l'implant (1) quasiment sans le toucher. Lors de la désolidarisation de l'organe de manipulation et de l'implant (1), seule se détache la connexion entre l'implant (1) et ledit organe. Le dispositif selon l'invention convient particulièrement pour la mise en place d'une ampoule stérile. Les instruments requis et leur utilisation pendant l'implantation s'en trouve simplifiés.
