  • Publication number: 20150359570
    Abstract: A surgical kit for placing an access tube (4) in the intervertebral disc of a patient, including a stylet (1), a cannula (2), a guiding wire (3) and an access tube (4) to be placed. In order to create access to the surgical site in a way that is easy and less stressful for the patient, an obturator (5) is provided for the access tube (4), the outside diameter of which corresponds to the inside diameter of the access tube (4) and which has a lumen of a diameter that corresponds to the diameter of the guiding wire (3).

  • Patent number: 8821378
    Abstract: The invention proposes a device for minimally invasive intervention in the skeletal region, in particular on the spinal column, having at least a cannula with a distal end generally bevelled in shape relative to a symmetrical axis of the cutting tool and an optical probe (endoscope) for insertion through the cavity of the cannula. The device is further characterized in that the cannula takes the form of a hollow cutting tool, in which the most distal region of the distal end comprises a cutting edge, which is incorporated into the edge of the wall of the cutting tool.

  • Patent number: 8449546
    Abstract: A cutter for spine surgery is provided, especially for use in the area of the delicate cervical spine. The cutter includes a cylindrical cutter shank with cutter teeth formed at the distal end thereof. The cutter teeth at the distal end of the cutter shank are formed by grooves in the wall of the cutter shank. The grooves become deeper and expand from the outer radius of the cutter shank towards the distal end such that teeth narrowing towards the distal end with increasing height are formed between them. This guarantees especially gentle cutting in the area of the cervical spine, without surrounding delicate tissue being additionally jeopardized.

  • Patent number: 8267937
    Abstract: A method for manufacturing bone milling cutters, wherein a milling cutter toothing (12) is created at a distal face of a tubular milling cutter shaft (10) of a bone milling cutter at a given outer diameter (D) of the milling cutter shaft (10). The following steps are carried out: determining the tube circumference (U) of the milling cutter shaft (10); ascertaining an average desired tooth height (Hgew) of the milling cutter toothing (12); ascertaining the desired tooth period length (LZ?) of the milling cutter toothing from the desired tooth height (Hgew) at given parameters of a tooth period pattern; dividing the tube circumference (U) by the desired tooth period length (LZ); rounding the results to an even number value (Qz); and dividing the tube circumference (U) by the value (Qz) in order to obtain the tooth period length (LZ).
