Percutaneous endoscope disc positioning device

The invention relates to a percutaneous endoscopic disc positioning device, in particular to a positioning device that can facilitate a surgical operator to precisely lock an intervertebral disc in a minimally invasive manner for percutaneous endoscopic disc operation.

Traditional intervertebral disc surgery mostly relies on the experience of the operator to determine the incision position of the operation, so it is easy to cause deviation or inaccurate positioning, and may damage the blood vessels and nerve tissue around the spine, causing serious complications. In addition, repeatedly adjusting the incision position will also prolong the operation time.

In addition, during the traditional intervertebral disc surgery, patients need to be irradiated with X-rays during the operation. Therefore, patients and medical personnel may be exposed to radiation. In order to avoid this risk, hospitals have to pay high costs for navigation and intraoperative imaging equipment.

In order to solve the above problems, a novel percutaneous endoscope disc positioning device is urgently needed in the art.

One object of the present invention is to disclose a percutaneous endoscopic disc positioning device which can provide a high-precision positioning operation, thereby generating a good disc operation result.

The second side leg 120 has a second longitudinal frame 121 and a second horizontal leg 122. One upper end of the second longitudinal frame 121 is connected to a second side of the beam 100, and the second longitudinal frame A lower end of one of 121 is connected to the second horizontal foot 122, wherein the second horizontal foot 122 is used to be placed on the operating table 400. The second longitudinal frame 121 has a guide portion 1211, and the guide portion 1211 has The plurality of guide perforations 1211a, and the orientation of the plurality of guide perforations 1211a are determined according to the X-ray tomographic image, so that the imaginary extension line of each guide perforation 1211a meets in one of the patients to be surgically treated. Intervertebral disc 211. That is, by directing each guide perforation 1211a to the intervertebral disc 211 to be surgically treated, an operator can make an endoscopic surgical instrument 500 select a convenient and appropriate guide perforation 1211a during the operation. The intervertebral disc 211 to be treated is touched and processed, thereby shortening the operation time.

In addition, the percutaneous endoscopic disc positioning device of the present invention may be an integrally formed device, which may be generated by, for example, but not limited to, 3D printing, and the positioning needle 300 may be made of steel or titanium alloy.

In addition, for the operation flow of the percutaneous endoscopic disc positioning device of the present invention, please refer to FIG. 2 to FIG. 5, wherein FIG. 2 shows the percutaneous endoscopic disc positioning device of the present invention straddling both hips of a patient. A schematic diagram of the outer edge of the bone; FIG. 3 is a schematic diagram of the percutaneous endoscopic disc positioning device of FIG. 2 with respect to a part of the spine of the patient; FIG. 4 is a schematic diagram of fixing two positioning pins 300 on the two vertebrae 210; and FIG. 5 is a schematic diagram of passing an endoscopic surgical instrument 500 through a guide perforation 1211a to access and process the intervertebral disc 211 to be surgically processed.

With the design disclosed above, the present invention has the following advantages:
