Definitions

  • the present invention relates to a forceps according to the preamble of claim 1.
  • Such tweezers is from the JP 10 165109 A known.
  • tweezers handle small-sized objects.
  • additional lighting is directed to the objects to be handled.
  • the light source can be introduced into the composite of tweezers.
  • the light is generally directed toward the gripping tip by a light source positioned in the longitudinal axis of the tweezers and in the vicinity of the fork point of the forceps legs (see also FIG EP 70 459 A1 or DE 102 40 490 A1 ). This is done either by direct air or the light is transported using clear polymers from the fork point of the tweezers, after coupling of the light, to the gripping tips and decoupled there.
  • a light guide can be placed on / in the tweezer leg (Patent JP10-151573, A ), or the tweezer material simultaneously fulfills the functions light guidance and handling of small objects ( JP10-165409, A ).
  • the light is transported via a coupled / exposed, portable light generator after actuation of a mechanical switch from the fork point of the tweezers to the gripping tip of the tweezers, using the light-conducting properties of clear plastics. This is very complicated and cumbersome and ineffective in the case described.
  • the light of the illumination device is difficult to direct to the objects to be handled by this type of light transport, since the fork point is a structurally disadvantageous location for light coupling and with respect to the gripping tip, the place of light extraction, the most distant location , A lot of light is lost due to the damping properties of the polymer used and / or the light can potentially escape unintentionally in many places.
  • a potential source of error represent the most cumbersome and or in various ways complex switch mechanisms, while limited functional game and thus lifetime. Also, they are usually very complicated to handle. In the worst case, the attempt of the switch operation forces a pull on the second hand and thus to interrupt the actual activity. The introduction of detent switches leads to waste of energy, and time-on mechanisms unnecessarily increase the complexity.
  • the invention has for its object to provide a device that allows easy handling of objects of small size even in unfavorable lighting conditions, minimizes the risk of possible static discharge, the source of error and the use of polymers as a construction material for light pipe and tweezer-type gripping function Handling disadvantage eliminated by mechanical switching mechanisms.
  • a combined light and gripping structure is established as gripping jaws of the tweezers.
  • the tweezers according to the invention comprises two tweezer limbs with first ends, the gripper / jaws, which are used to handle small objects and at the same time the defined directed, as well as the partially undirected coupling of the light coupled into the tweezer limbs to illuminate the object to be gripped and the nearer environment use exact orientation.
  • the invention relates to a light-tweezers with two pincer arms at the ends of gripping / -Leuchtbacken are provided, and at least one light source with switchable power supply, characterized in that the light source / -n switchable with an electrical contact circuit is / are.
  • the tweezer legs consist at least partially of transparent plastic and form a light guide for the light of the light source.
  • a preferred form of the light-tweezers is characterized in that the touch circuit has at least two contact zones of electrically conductive plastic, in particular of transparent electrically conductive plastic.
  • the electrical touch circuit is based on a Darlington circuit.
  • the polymer of the electrically conductive plastic for the contact zones is preferably selected from the series of polythiophenes, polyanilines or polypyrroles. Particularly preferred is polyalkylenedioxythiophene, most preferably poly-3,4-ethylenedioxythiophene.
  • a preferred variant of the light-tweezers is characterized in that the light of the bulbs is passed through the tweezer legs to the gripping / -Leuchtbacken and is coupled on the inside via the gripping / -Leuchtbacken.
  • the luminous means preferably comprises a light-emitting diode or laser diode.
  • the power supply preferably comprises an accumulator or a battery.
  • the transparent plastic of the tweezer limbs is preferably based on polycarbonate, polyester, polyacrylate, particularly preferably polycarbonate or PMMA.
  • the contact zones are mounted on both tweezer legs. The light is switched on by touching both zones by hand.
  • the coupling of the light takes place at a structurally and technically suitable location between the two ends of each leg.
  • the legs are fabric, form or force-fitting resiliently connected to each other and thus fulfill their tweezer-like gripping function.
  • the electrical components for generating the required light are positioned or integrated spatially between and / or in the respective forceps legs.
  • a mechanical switch for switching on / off the light source is eliminated by a technically diverse kind of application of a layer of current-conducting, intrinsic polymer.
  • This layer fulfills both the task of antistatic, as well as the contact / buttons of an electrical contact circuit, achieved by a spatial separation / interruption of the coating between the tweezer legs, which thus form the two required separate contact surfaces.
  • the touch circuit since the lighting of the tweezers is triggered only on contact and thus only in use. The result is that the circuit saves power and prevents premature or unwanted discharge of the batteries. Furthermore, mechanically moving parts and thus wear and error sources are eliminated.
  • the invention also provides the use of the light-tweezers as a medical device, in particular as a tick tweezers.
  • a luminous tweezers comprises two resiliently connected tweezer legs 3, which consist of a clear polymer (polycarbonate) to fulfill the light pipe and of an upper part of a polymer, ceramic or metal to fulfill the gripping function. At the left end, the tweezer legs are spaced apart to receive an object that is small in size.
  • the lighting of the small objects to be gripped takes place by coupling the light generated in the light emitting diodes 5 over a defined area in the transparent body of the forceps legs and coupled in the defined designed gripping / lighting area 9 in the direction of the object to be gripped.
  • the electrical components of the illumination device 1,4,5,6,7,8 are partially positioned in the respective tweezer limbs, partly between the respective tweezer limbs.
  • the lighting system with touch circuit by using an antistatic contact surfaces as an electrical contact circuit consists of one or more light sources 5 (LED's), a power storage (battery, rechargeable battery or capacitor) 7, which via a holder 6 with a support unit for the electronic components (board, Foil) 8 is connected, with which the light sources 5 are in communication.
  • the tweezer legs are each provided in a partial area with a current-conducting polymeric coating 1.
  • a positive, positive or cohesive connection 4 in this case in a first embodiment, an adhesive 4 by current-conducting adhesive with the electrical line 10.
  • a connection is made between the two forceps limbs, preferably by the user's fingers or hand areas during the use of the tweezer-like gripping tool 2.
  • FIG. 3 A schematic representation of a possible implementation of such an electrical contact circuit using an antistatic or current-conducting, based on an intrinsic polymer, coating in illuminated tweezers shows FIG. 3 .
  • Characteristic is the structure of the circuit of a primary and a secondary circuit which are connected by an energy-sensitive circuit.
  • the primary circuit supplies the light source (-n) with energy
  • the secondary / control circuit together with an energy sensitive circuit, here established in a first embodiment by a transistor arrangement of the so-called Darlington circuit, represents the control or the switching mechanism of the primary circuit.
  • the construction of the embodiment of the contact circuit in the secondary circuit shown here consists of the Darlington arrangement, on whose first base one of two spatially separated areas of the intrinsic polymer contact area is located.
  • This contact surface is applied to one of the two pincer legs. It is transparent in its appearance and at the same time assumes the task of an antistatic.
  • the second intrinsic contact surface is located on the second pincer leg, is the first of its kind ( FIG. 1 ) 1 and is connected to the plus pole of the power source. About an addition to be established physical connection between the contact surfaces of the control circuit is closed, the transistors turned on and thus turned on the primary circuit. After interruption of the physical connection and the transistor circuit immediately interrupts the primary circuit and thus switches off the light sources 5.
  • the coating consists of an electrically conductive polyethylene dioxythiophene / polystyrene sulfonic acid layer.
