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...

Abstract

The invention discloses a linear bone file with a nerve monitoring function, the linear bone file is in a flat belt shape and is provided with a working part and a traction part, the working part comprises a filing area and a frame, the frame is fixed with the outer edge of the filing area, the filing area is a chain-shaped strip formed by longitudinally arranging or longitudinally and transversely flexibly connecting two or more filing pieces, and the traction part is connected with the chain-shaped strip. The working face of each filing piece is provided with filing lines, the back face of each filing piece is smooth, the traction parts are arranged at the two ends of the working part and fixedly connected with the frame, and at least one nerve monitoring element is arranged on the surface of the working part and / or the traction parts. The traditional mode that a high-speed abrasive drill is used for excising the vertebral plate is optimized, the vertebral plate is rasped through the fret saw, operation is easy, higher safety is achieved, nerve electrophysiological signals of the surgical site can be monitored in an operation, nerve function positioning and function evaluation can be conducted, surgical operation can be assisted and guided, and nerve damage is avoided.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a linear bone rasp with nerve monitoring function. Background technique [0002] Spinal stenosis is a condition in which the spinal cord or nerve roots are compressed due to abnormal narrowing of the vertebral foramen or intervertebral foramina. The most common spinal stenosis is lumbar stenosis, followed by cervical stenosis. Symptoms caused by lumbar spinal stenosis include lower extremity pain, paresthesia, muscle weakness, and difficulty walking. Symptoms develop gradually, and in severe cases, affect urinary incontinence, difficulty defecation, and sexual dysfunction. There are many causes of spinal stenosis, including degenerative disc disease, spinal cord tumors, trauma, rheumatoid arthritis, and genetic disorders. The most common degenerative lumbar spinal canal stenosis, the incidence rate of people aged 50-65 reaches 8%, and the incidence rate of people over...
