Definitions

  • the invention relates to a surgical instrument according to the preamble of claim 1 and a method for producing a surgical instrument.
  • the invention relates to a surgical instrument having an outer tube in which an inner tube is rotatably mounted, which is provided at its free end with a tool.
  • Such instruments are also referred to as so-called shaver blades.
  • shaver blades For the state of the art, reference is made by way of example to EP 1 006 898 B1.
  • the outer tube is rotationally fixed by means of a coupling device mounted on one drive, while being in ⁇ enrohr rotated with a relatively high speed of up to 12,000 rpm "1
  • Such shaver blades are used for example in arthroscopy to invasive remove tissue and removing it through the inner tube.
  • the invention has for its object to provide a surgical instrument and a manufacturing method of the type mentioned above, which avoids the disadvantages of the prior art with a simple structure and simple, cost manufacturability and allows safe storage, especially in design of the tool with a milling head ,
  • the milling head is fixed to the inner tube, wherein the milling head is provided at its end remote from the toothing having a larger diameter than the diameter of the inner tube.
  • the enlarged diameter diameter portion of the milling head comes into abutment with the inner wall of the outer tube, while the inner tube itself is securely guided with a constant gap or distance in the outer tube. This results in an effective slide bearing.
  • the thickened in diameter portion of the milling head forms part of the sliding bearing. It is understood that the end portion of the milling head formed larger in diameter with respect to its axial position, its axial dimensioning and its configuration can be adapted to the particular circumstances.
  • the sliding bearing surface formed by the enlarged in diameter portion of the milling head sliding surface can be made according to the invention of the same material as the inner tube.
  • the sliding bearing surface of the thickened in diameter region may also be provided with a different material, which is applied for example in the form of a coating. Since, according to the invention, only a relatively small increase in diameter is required in order to realize a bearing of the front region of the inner tube in the outer tube, the sliding bearing surface can be formed, for example, by an electrolytically applied coating or the like.
  • FIG. 1 is a schematic, shortened in length side view of an embodiment of the surgical instrument according to the invention.
  • FIG. 2 shows an enlarged detail view, partly in section, of the distal end region of the surgical instrument according to FIG. 1.
  • the surgical instrument according to FIG. 1 comprises an outer tube 1, in which an inner tube 2 is rotatably mounted.
  • an inner tube 2 is rotatably mounted.
  • the front portion of the outer tube 1 is chamfered or provided with an opening, so that a mounted on the distal end of the inner tube 2 milling head can be brought into use.
  • the outer tube 1 may be, for example 150 mm long.
  • the milling head 3 is fixed to the inner tube 2, for example, welded.
  • the milling head has at its end region adjacent to the inner tube 2 a sliding bearing surface 5 which is larger in diameter than the outer diameter of the inner tube 2, so that the sliding bearing surface 5 is slidably guided on the inner wall of the outer tube 1 and together with this Plain bearing forms.

Abstract

L'invention concerne un instrument chirurgical comprenant un tube externe dans lequel un tube interne est logé rotatif. A son extrémité libre, le tube interne est pourvu d'un outil qui comprend une tête de fraise fixée sur le tube interne. L'instrument chirurgical selon l'invention est caractérisé en ce que la zone d'extrémité de l'outil éloignée de la tête de fraise a un diamètre supérieur à celui du tube interne et forme une surface de palier lisse venant s'appuyer contre une surface interne du tube externe.
