Definitions
- the present invention relates to a customizable holding device for holding a medical tool wherein the holding device
- the present invention relates to a method for
- Gripping areas can not optimally correspond to an individual finger position preferred by the user.
- a well-known medical tool is for example a
- the contra-angle represents the link between the so-called turbine head and the so-called supply hose.
- Supply hose are pneumatic and / or electric
- Interface between user and tool for example, when a carious sites of a tooth is removed.
- This elbow is manufactured in mass production.
- the grip portion of this elbow can not have a shape due to the mass production, which an individual hand and finger shape of the
- the elbow is held similar to a pen with the fingers and the palm. To ensure that when using the elbow
- Finger position is customizable and in particular allows a secure holding the medical tool with reduced effort. It is another object of the invention to specify a method for producing such a retaining piece.
- This object is achieved by a method for producing a
- Holding device according to claim 1 and by a holding device according to claim 3.
- Holding device is available, which allows a positive connection between the fingers and the holding device is formed. As a result, when holding the necessary force is reduced by the amount that is necessary in the prior art to produce the adhesion between the fingers and the medical tool.
- 1 shows a schematic device for laser sintering 2 shows a medical tool without holding device
- FIG. 4 shows the impression base with impression mass in the ground state
- FIG. 5 the impression base with individual impression
- 6 shows the medical tool with holding device
- the layer-by-layer generation of objects by means of laser sintering method will first be described by way of example with reference to FIG. Under laser sintering process, the skilled person understands a layer-wise generation of an object.
- the device comprises a building container 1, in which a carrier 2 is provided for carrying an object 3 to be generated.
- the carrier 2 can be moved via a height adjustment device 4 in the vertical Z direction within the construction container 1.
- the carrier 2 is lowered a certain amount.
- the plane in which the carrier 2 is now located is slightly below the plane in which the edge of the building container 1 is located.
- a coater 12 is movable in the Y direction. This level is called work level 5.
- the volume of the first layer of the manufacturing process is defined by the working plane 5, the plane in which the carrier 2 is located and the inner edge of the building container. 1
- the powdery material is for this purpose removed from a reservoir 11.
- controller 10 which controls a deflector 8 and optionally a focusing unit 9 such that a laser beam 7 can be directed to any point of the working plane 5.
- the controller 10 is driven by data which include the decomposed into individual layers structure of the object to be generated.
- the powdery material lying below the point of impingement is first melted, whereby the individual grains of the powdery material flow together.
- the cooling of the liquefied material begins. Once the liquefied material has cooled below its melting temperature, solidification occurs. The solidified areas of the layer are surrounded by unconsolidated powdered material.
- the carrier 2 becomes something
- volume which can be replenished by the coater in the manner described above. After refilling this volume, as described above, the next layer of the object to be generated can be produced. These steps are repeated until the object to be generated is completely manufactured.
- suitable powder or powder mixtures are used.
- powders include, for. As plastic powder such as polyamide or polystyrene, PAEK (polyaryl ether amides), elastomers such as PEBA (polyether block amides), metal powder, eg. As stainless steel powder or other, adapted to the purpose of metal powder, in particular alloys,
- plastic-coated sand or ceramic powder plastic-coated sand or ceramic powder.
- the medical tool is the dental hand drill 21 shown in FIG.
- the detection of the shape of the hand drill 21 can be done for example by a 3-D scanner, it is also possible to use existing CAD design data.
- Impression base also called impression base.
- This impression base is adapted to the shape of the medical tool 21 for which the holding device according to the invention is provided.
- the impression base 22 is based on the shape of the medical tool, here the shape of the hand drill 21 constructed by CAD.
- FIG. 3 shows a possible embodiment of an impression base 22.
- Impression spoon provided with holes 23 and has a wall thickness of 2 mm.
- the diameter of the holes 23 is about 4 mm.
- FIG. 4 shows the impression base 22 on which an impression compound
- cured silicone is applied in a state before an impression was taken.
- the impression base 22 with the applied impression compound 24 according to the user of the medical tool 21 is given in the hand.
- Impression material 24 in the interior of the impression base 22 is for further
- FIG. 5 shows the result of an imprinting process. This results in an exact individual fingerprint 25 in the impression compound 24.
- the surface of the fingerprint 25 later offers the contact surface for a positive holding when using the medical tool.
- the unit of the impression base 22 with the individually shaped impression mass 24 is referred to below as an impression. For digital further processing of this impression this is now detected for example with a 3-D scanner.
- the 3-D data of the impression are processed so that a 3-D
- Model of the holding part according to the invention results, which is suitable to be mounted on the outside of the hand drill 21.
- the volume of the individual impression, the volume of the medical tool is subtracted.
- the volume of the holding device according to the invention remains.
- Powder mixtures are used. It is likewise possible to generate the object according to the invention by means of another method for additive production.
- the holding device according to the invention is used in one
- a suitable material is polyamide (for example PA 2200, PA 2, PA 11). This material is biocompatible and easy to sterilize.
- FIG. 7 shows a possible further development of the holding device 27 according to the invention with a hinge 28 and a clip connection 29.
- This holding device 27 is opened Clip connection applied to the medical tool, folded and finally closed by means of the clip connection 29. This then creates the desired fit.
- the connection between the holding device and medical tools whose shape does not allow a positive connection with the holding device, it is provided, the connection between the holding device and
- the inventive concept is realized, the user for the transmission of power to the medical workpiece a positive connection for his fingers or his hand for
- the holding device according to the invention has been shaped according to an ergonometric holding position, whereby the force required to hold the medical tool can also be reduced.
- the invention is industrially applicable in the field of medical devices.
