Description

Technical Field

[0001] This specification relates to the field of medical devices, and in particular to a surgical tool. Background Art

[0002] With the development of medical technology, minimally invasive spinal endoscopic surgery is becoming more and more widely used. Minimally invasive spinal endoscopic surgery is to first use a working cannula to establish a surgical channel from the skin incision to the surgical area, and then implant the spinal endoscope or surgical instruments into the surgical area through the working cannula for surgical operation.

[0038] The inner cavity 002 is used to accommodate the fusion device, so that the fusion device is placed in the surgical area through the inner cavity 002 .

[0039] The fiberscope channel 01 is disposed inside the tube wall 001 and is communicated with the inner cavity 002 . The fiberscope channel 01 is used to place a fiberscope, which is used to provide a visual field of the surgical area during the placement of the fusion device.

[0040] Specifically, the fusion device can be placed through the inner cavity 002 of the hollow tube body 00, so that the fusion device can be placed in the surgical area through the inner cavity 002, and the fiberscope can be placed through the fiberscope channel 01, so that the fiberscope can provide a visual field of the surgical area during the placement of the fusion device without occupying the inner cavity of the hollow tube body, thereby ensuring that there is a surgical field of view when placing the fusion device, and avoiding accidental damage to the surgical area during the process of placing the fusion device without a visual field. In addition, the fiberscope channel 01 is not only deployed inside the tube wall 001, but also communicated with the inner cavity 002, which can ensure that the fiberscope channel 01 can accommodate the fiberscope and increase the visual field of the lens of the fiberscope, so that the fiberscope can observe a larger surgical area. At the same time, the structure of the tube wall 001 is retained as much as possible, so as to maintain the overall firmness of the surgical tool. Among them, the diameter of the fiberscope can be 1mm, and it can also be a fiberscope of other diameters, which is not specifically limited in this specification.

[0041] In this manual, if Figure 2 As shown, Figure 2 is a schematic diagram of the structure of another surgical tool provided in this specification, Figure 2 The surgical tools shown are Figure 1 The surgical tool shown may also include a flushing channel 02, which is disposed inside the tube wall 001 and is used to allow water to flow through to flush the surgical area. Specifically, water may be injected into the flushing channel 02, and water may flow out through the flushing channel 02 to flush the surgical area, thereby ensuring a clear field of vision in the surgical area.

[0042] Therein, a preset angle is formed between the direction from the center of the cross section of the fiberscope channel 01 to the center of the cross section of the inner cavity 002 and the direction from the center of the cross section of the flushing channel 02 to the center of the cross section of the inner cavity 002. The preset angle is a pre-set angle, which can be 180° or 60°, and this specification does not impose any specific restrictions.

[0043] In addition, when the angle is 180°, the fiberscope channel 01 and the flushing channel 02 are mirror images of each other, as shown in FIG. Figure 3 As shown, Figure 3 is a schematic longitudinal section diagram of a surgical tool provided in this specification, Figure 3 for Figure 2 A schematic longitudinal section diagram of the surgical tool shown.

[0044] In this specification, the head end of the hollow tube 00 is provided with a tongue-shaped head 03, and the tongue-shaped head 03 includes a first water outlet 031.
