Definitions

  • the invention relates to a drilling method, a drill intended for surgical purposes with an attachment and a fixable to the attachment by means of a coupling element drill and an attachment for a certain purpose surgical drill.
  • Such a drilling machine and such a drilling method are used in practice, for example, to allow a screw connection of fracture surfaces by means of an osteosynthesis plate and thereby promote the convergence of the affected bones.
  • the osteosynthesis plate is screwed with several screws in each half of the broken bone, in order to connect them.
  • the unnatural force distribution in the bone caused by the implant has a significant influence on the fractures that occur due to the significantly increased elastic modulus of the implant material compared to the bone.
  • This load shielding in the bone leads to a decay of the bone substance and correspondingly reduced stability.
  • stress peaks are formed, which consequently lead here to a fracture of the bone.
  • DE 10 2006 058 937 A1 relates to a drilling machine with a receptacle, which has a contact surface for a region facing away from the drill of a prosthesis shaft of a prosthesis, in particular a joint prosthesis, receiving bone.

  • the hand drill is intended for introducing an elongate fixing aid into a bone under sterile conditions.
  • the hand drill is equipped with a motor-driven rotatable drive shaft, which is kinematically connected to a drill wire chuck.
  • the drill wire chuck is designed to be open in such a way that the fixing aid can be guided through the drill wire chuck in an open position and is non-rotatably connected to the drill wire chuck in a closed position.

  • the drill guide is provided with means for varying the distance between the stop surface and the front end of the sleeve so as to allow the surgeon to safely insert bores into the bone.
  • DE 693 26 397 T2 already discloses a device for machining a workpiece with a tool holder and a rotating cutting tool, which has a coolant channel on an outer surface. This extends from the rear end of the cutting tool to a region near the free end, so that the coolant is applied directly to the rake surfaces of the cutting edges of the cutting tool.
  • a drill for dentistry has a longitudinal channel for the supply of coolant to the tool, which opens at the working end of the tool to the outside.
  • the cooling liquid also enters the milling head cavity through the openings, wherein drilling dust is also swept into the milling head cavity. In this way, the heat is to be reduced at the place of its formation, ie at the point where the cutting surfaces rub against the substance to be removed.
  • DE 27 30 227 A1 relates to an apparatus for drilling bone, in which the drill is driven with a reciprocating rotary motion whose amplitude is smaller than a full revolution.
  • a sleeve surrounds the drill, which is pressed forward against the bone to form a channel for receiving the waste. Although the chips are thereby collected in the sleeve, but not led away from the drilling site.

  • drilling machines for machining high-strength materials are necessarily designed as drill presses, since an axial coolant supply due to the sealing side of the processing zone side facing previously could only be realized by a frictional connection of the drill with a chuck, which has the consequence that a manual drilling and a manual drilling device could not be realized.
  • the object of the invention is to provide a substantially improved drilling method and an attachment intended for carrying out the method for a manual drill used in surgery, as well as a manual drill provided with such an attachment, whereby an undesirable heat input, in particular due to drilling in implant materials, is significantly reduced.
  • a drilling method of a drill intended for surgical purposes for introducing bores into bone and fixed therein implants is created by following a coolant through a drill of a secondary cutting edge in the implementation of the drilling process and following the twist angle of the drill behind at least one main cutting edge of the drill emerges.
  • the coolant is deflected into an area behind a chip to be generated and thereby flows around the chip and the drill.
  • the separated chip is transported according to the direction of rotation of the drill from the coolant through a flute of the drill to a drill bit facing away from the chip receiving and collected by a chip receiving.
  • the chip holder includes the drill and adapts to the drill penetration depth accordingly.

  • the hot metallic chips of the implant material thus do not pass uncontrollably into the surrounding tissue. Rather, the chips are conveyed on the outside of the drill in the chip holder. This ensures not only a reliable removal of the chips, but also an uninterrupted cold chain of the chips.
  • a particularly advantageous embodiment of the present invention is achieved in that the drill has a plurality of outlet openings, in particular inclined with respect to the rotational axis of the drill, for the coolant.
  • a particularly efficient cooling of the resulting chips is ensured, in particular by each main cutting edge is associated with a separate outlet opening.
  • a sufficient flow through each flute is achieved, with an inclined arrangement of the outlet opening significantly improves the conveying effect.
  • An undesirable, in particular uncontrolled distribution into the surrounding tissue is excluded.
  • no feed movement is produced by the exiting coolant jet in the opposite direction.
  • At least one outlet opening for deflecting the coolant into an area directly behind a main cutting edge of the drill is executed.
  • the coolant jet enters the gap between the chip and the main cutting edge, so as to achieve the greatest possible cooling effect directly in the area of chip formation.

  • the chip receiving device reliably automatically lays against the edge region enclosing the borehole.

  • the biasing force can also be made adjustable. Furthermore, it is advantageous if the chip receiving rotatably connected to the housing of the drill and thus has a high stability.

  • the contact surface can also be connected for single or multiple use releasably connected to the chip receiving.
  • the chip receiving is connected to a suction. This allows a simple removal of the entering into the chip receiving coolant, so that the volume of the chip receiving only needs to be dimensioned according to the chip volume and thus relatively small. Furthermore, a negative pressure can be generated in the interior of the chip receptacle so as to favor the return flow of the coolant exiting at the drill bit, including the chips.
  • the proportion of traceable coolant in this way is comparatively high.
  • the coolant is a biocompatible liquid, in particular a saline solution, and thus no adverse effects on the tissue or the bone substance is to be feared.

Abstract

L'invention concerne un procédé de perçage et une machine de perçage (1) destinée à des fins chirurgicales comportant une garniture (2) et un foret (4), ainsi qu'une garniture (2) destinée à une machine de perçage (1). L'invention a pour objet de réduire sensiblement l'entrée indésirable de chaleur dans le tissu sous l'effet de perçages dans un matériau d'implant. A cet effet, le foret (4) peut être traversé par un réfrigérant. Après sa sortie par un orifice de sortie (7) dans la zone de la pointe du foret au point de perçage, le réfrigérant est dirigé avec les copeaux qu'il contient le long de la rainure à copeaux du foret (4) vers un réceptacle à copeaux (8) cylindrique qui entoure radialement le foret (4).
