Definitions

  • the present disclosure relates to a hand-held medical instrument with an instrument body which has at least one gripping section, at least one effector section and an RFID tag which is preferably used as a glass/ceramic tag according to the underfloor principle in the instrument body.
  • US Pat. No. 7,898,420 B2 discloses a transponder device and/or a housing for marking a surgical device, such as a metallic surgical instrument.
  • the transponder device is intended to have a non-resilient, preferably non-metallic, rigid transponder housing which can be attached to a piece of surgical equipment.
  • the housing has a transponder receiving cavity that is at least 1 millimeter and preferably 2 millimeters from any part of the surgical device when the housing is attached to the surgical device.
  • the housing can be removably attached to the surgical device or permanently attached. In use is a transponder installed in the transponder receiving cavity.
  • EP 3 146479 A1 describes an RFID tag assembly having a passive RFID tag on metal and a mounting member.
  • the passive, metal-mounted RFID tag is arranged in such a way that an RF signal can be transmitted.
  • the mounting member is made of an electrically conductive material and includes a base portion and at least one wall portion that extends with respect to a first surface of the Base portion extends outward.
  • the at least one wall section is configured to at least partially define a recess in which the RFID tag is connected to at least one wall section.
  • a surgical instrument to which an RFID tag assembly is attached is also provided.
  • RFID tags are comparatively small components
  • the RFID tag arrangements/devices subsequently applied in the prior art form additional points of attack for contamination and are also a hindrance when handling the surgical or medical instruments.
  • attached RFID tags can form gaps and cracks (nests of viruses and bacteria) in which germs or the like can settle, which is of course very disadvantageous in medicine.
  • the subsequently attached RFID tags may restrict the handling of the ergonomically shaped surgical instruments and, in the worst case, can form corners and edges on which a surgeon's glove can be damaged on contact or a hole/tear can develop.
  • Another disadvantage of the prior art is that passive RFID tags have to be placed at a short distance from a reading device due to their sometimes short transmission range. For this reason, in the prior art it is often only possible to subsequently apply the RFID tags to an outer surface of a surgical instrument in order to keep the distance between the RFID chip and the reading device as small as possible. It is important for the above reasons to ensure that the intended outer surface on a Instrument location is located, which has only a small impact on the instrument handling and still allows a sufficient readout quality.
  • Such a treatment cycle includes manual pre-cleaning (with brushes), if necessary ultrasonic cleaning, cleaning in the RDG (cleaning and disinfection device), if necessary oiling and sterilization.
  • the following information about the medical products is important due to the issues relating to tracking, tracing and lifecycle management, which will become increasingly important in the future, and the provision of evidence in the event of a complaint:
  • an integrated arrangement initially means a weakening of the material on the hand-held instrument
  • an additive arrangement means a change in the external geometry of the hand-held instrument.
  • a material weakening can basically be reduced by additional material reinforcement in the weakened area, by taking over the material weakening through the integrated insert itself (bridging) or by choosing the position of the material weakening in such a way that it does not play a role in the intended instrument insert. This can be achieved by the fact that the selected position already has a large material thickness, which is only slightly influenced by the integration of a tag.
  • the object of the present invention is therefore to provide a medical device or a medical/surgical instrument, in particular Provide ring instruments with an RFID tag, which ensures good and safe handling, both with regard to the instrument properties as such and to the data transmission properties of the RFID tag.
  • a further object of the present invention is preferably to ensure good cleaning and/or sterilization of the device according to the invention/the medical instrument equipped with it.
  • An additional object of the invention is more preferably to ensure an improvement in reception of one or more integrated/attached RFID tags.
  • the core of the present invention consists essentially in the fact that in the instrument body, in an area that is essentially force-free when the hand instrument is engaged (e.g. closing movement of pliers/cutting movement of scissors, etc.), a recess or breakout is formed into which a separate underfloor tag holder (Material bridge) is used, which fills the recess or the breakout in a form-adapted manner to the hand instrument. Accordingly, the position of the material weakening is selected in such a way that the position is not integrated in that force flow via which an engagement actuation force is conducted.
  • the medical hand instrument is a ring instrument, such as (surgical) scissors, forceps or the like.
  • a medical ring instrument with an instrument body which has at least one gripping section, at least one effector section and an RFID tag, which is preferably used as a glass/ceramic tag according to the underfloor principle in the instrument body is (integral arrangement), wherein a recess or breakout (notch or material interruption) is formed in the instrument body in an engagement actuation of the hand instrument essentially force-free area, in which a separate underfloor tag holder (Material bridge) is used, which fills the recess or the breakout in a form-adapted manner to the hand instrument.
  • a separate underfloor tag holder Material bridge
  • This geometric modification and coordination of the surrounding components increases the receptibility, especially the distance to the reading and writing device, de RFID tags.
  • medical hand instruments in particular ring instruments, it is possible to be able to absorb force during operation and also to implement the principle of the slot antenna.
  • an RFID tag/chip can be significantly influenced by this geometric installation situation as well as the surrounding components.
  • the RFID tag is preferably always installed below the floor (i.e. set back from the instrument surface), so that the RFID tag is placed below the opening and not protruding beyond it.
  • RFID tags can also be understood as meaning NFC tags, which represent a sub-form of RFID technology.
  • an NFC tag can also be used according to the invention instead of an RFID tag.
  • the RFID tag is an RFID transponder for storing information associated with a specific object (in this case the medical instrument). This so-called “identifier” can be individualized according to the requirements of the respective process.
  • the RFID tag preferably consists of:
  • At least one microchip preferably sized around a few millimeters in diameter
  • the housing preferably being watertight and/or airtight and preferably protecting the transponder electronics from the environment
  • the RFID tag of the invention is a passive RFID tag.
  • the RFID tag preferably also has a (rod-shaped) ferrite core with a coil wound around it.
  • the built-in RFID tag/chip is preferably a glass tag, which can be procured in different sizes.

  • the geometry surrounding the RFID tag/RFID pill/glass tag can consist of any freely selectable materials. However, there must always be a slit parallel to the glass tag on the outside surface of the product.
  • the coil is located directly in the groove (below). This opening can either be free or designed with a signal-permeable material.
  • the size varies in length and width to optimize the reading and writing distance. It is advantageous if the at least one gripping section has two branches, the at least one effector section has two handles ending in a ring shape, and the recess or breakout is arranged on one side of the at least one handle ending in a ring shape, which is in the direction away from the other handle ending in a ring shape Handle of the hand instrument points. An increased force takes place when closing the medical ring instrument.
  • the underfloor tag mount When the ring instrument is opened, a significantly lower force acts on the ring-shaped handle of the medical hand instrument. This provides an optimized way of installation to achieve reliability and signal gain/receivability. Because the underfloor tag mount is located on the outside of the annular tapered handle in a direction away from the second handle, the underfloor tag mount experiences less reopening force due to the location. The geometry of the underfloor tag holder described below prevents it from being pushed out if increased force is applied. By optimizing the geometry of the underfloor tag holder (plastic part), the force can be absorbed much better and the plastic carrier/underfloor tag holder is prevented from escaping.
  • the underfloor tag mount is designed so that when an increased force is applied, the force flow will cause the underfloor tag mount to flex/give but not disengage.

  • the underfloor tag holder 7 tends to be pushed out of the handle 9 when a force acts on it, possibly due to increased effort to become. Due to the above-described optimized geometry of the underfloor tag holder 7, the force can be absorbed much better and the underfloor tag holder 7 is prevented from escaping.
  • Fig. 12 is therefore an illustration to clarify the power flow without the advantageous anchor points 12. It does not represent a solution within the meaning of the invention. If an increased force is applied, the power flow (according to the arrows shown) would cause the underfloor tag holder 7 bends and is detached from the anchor points 12, if necessary the anchor points 12 are sheared off and the underfloor tag holder 7 is detached from the handle 9. In this case, the RFID tag 4 would most likely also break.

  • the RFID tag 4 can be placed (arbitrarily) as a result of its arrangement on the medical instrument, namely under the floor, so that when the hand instrument 1 is inserted into the instrument holder 16, it comes to rest exactly above the readout device 15 and so the transmission distance between the RFID tag 4 and the reading device 15 is minimized.
  • the positioning of the RFID tag/glass tag 4 is optimal in order to insert at least one (hand) instrument 1 in a corresponding instrument holder 16 in a vertical position.
