Embodiment 1
[0041] This embodiment discloses a linear bone rasp, such as figure 1 As shown, the linear bone rasp is in the shape of a flat belt and has a pulling part 1 and a working part 2. The working part includes a frame 3 and a rasp area 4. The frame 3 is fixed to the outer edge of the rasp area 4. The rasp Zone 4 is two or more files 5 arranged longitudinally or flexibly connected longitudinally and laterally (such as figure 2 As shown), the working surface of each file has a filing texture and the back is smooth. The pulling part 1 is located at both ends of the working part 2 and is firmly connected with the frame 3. At least one nerve monitoring element 6 is arranged on the surface of the working part and / or the pulling part.
[0042] The nerve monitoring element is selected from the group consisting of electrodes, sensors, outer envelopes with sensing properties, patches or coatings with sensing properties, conduction pathways made of media that conduct nerve signals, and the me...
Embodiment 2
[0049] like Figure 4 As shown, this embodiment provides an orthopedic surgical device on the basis of Embodiment 1, including a guide tube 7, a guide wire 8 and a linear bone rasp 9 according to the present invention.
[0050] Preferably, at least one nerve monitoring element is provided on the head end of the guide tube 7 and the guide wire 8 and the surface of the linear bone rasp 9 .
[0051] Taking spinal canal decompression surgery as an example, the use process of the surgical robot of the present invention will be described in combination with guide tubes, guide wires and linear bone rasps. The specific steps are:
[0052] (1) Use the head end of the guide tube 7 to penetrate the intervertebral foramen, and use the hardness of the guide tube to loosen the gap between the ligamentum flavum and the cone-plate;
[0053] (2) Fix the guide wire 8 to the linear bone rasp 9 through the internal through hole 10 of the linear bone rasp grinding area and the hollow hose of the...
