| 摘要 |
The invention relates to a method for attaching, through soft tissue, an electric electrode to bone tissue (hard tissue), in which the electrode is provided with a rigid electrode tip and a highly flexible cable which is connected to the electrode tip and which is electrically insulated against surrounding soft tissue. The method comprises the following steps, given by way of example: (a) applying one end (3a) of an elongated guide means (1) having a longitudinally extending channel (2) to an outer surface (4) of soft tissue (5) immediately adjacent a fracture location (6) of bone tissue; (b) moving one end (3a) of the elongated member through the soft tissue towards said bone tissue; (c) introducing through the channel (2) firstly an electrode having a rigid electrode tip (20) and a flexible cable (25) connected thereto, and secondly a tube (25) which embraces the cable and which coacts with the electrode tip via coupling means; (d) displacing the tube (25) relative to the guide means (1) in a manner to move the electrode tip (20) towards the hard tissue; (e) causing the electrode tip (20) to penetrate the bone tissue, by exerting a force on the tube (25) in a direction towards the bone tissue (7); and (f) removing the tube (25) and the guide means (1) in a manner such as to leave a part (22a) of the flexible cable exposed above the outer surface (14) of the soft tissue (5), such as to enable the cable to be connected to an electric current or voltage source. |
