Figure 6

[0043] ​The angle adjusting assembly A3 in the embodiment comprises a rotating block lock core A31 and a rotating block spring A32, both of which are arranged on the sleeve fixing frame A12, and the two ends of the rotating block spring A32 are respectively in abutment with the rotating block lock core A31 and the sleeve fixing frame A12. The rotating block lock core A31 is provided with rotating block lock teeth A33, which are matched with the rotating block clamping groove A26. When the rotating block lock core A31 is pressed to make the rotating block lock teeth A33 disengage from the rotating block clamping groove A26, the rotating of the mirror seat rotating block A22 relative to the mirror seat fixing block A21 is realized. When the rotating block lock core A31 is released, the rotating block lock teeth A33 can be clamped into the rotating block clamping groove A26 under the action of the rotating block spring A32, so as to fix the mirror seat rotating block A22 relative to the mirror seat fixing block A21.

[0044] The distance adjusting assembly A4 in the embodiment comprises a mirror seat lock core A41, an unlocking block A42, an unlocking block nut A43, an unlocking block handle A44 and an unlocking block spring A45. The mirror seat lock core A41 and the unlocking block spring A45 are both arranged on the mirror seat main body A23, and the two ends of the unlocking block spring A45 are respectively in abutment with the mirror seat lock core A41 and the mirror seat main body A23. The unlocking block A42 is arranged on the mirror seat main body A23 through the unlocking block nut A43. The mirror seat lock core A41 is provided with an unlocking clamping groove A48, one end of the unlocking block A42 is located in the unlocking clamping groove A48, and the unlocking block handle A44 is arranged at the other end of the unlocking block A42.

[0045] The mirror seat lock core A41 in the embodiment can also be provided with a lock pin limiting groove A49, and the mirror seat main body A23 can also be provided with an unlocking block limiting pin A46, which is located in the lock pin limiting groove A49 and can be used to limit the pressing distance of the mirror seat lock core A41. That is, when the length of the intervertebral disc mirror device B relative to the fixing device A is adjusted, the mirror seat lock core A41 needs to be pressed, and the unlocking block limiting pin A46 can be used to limit the mirror seat lock core A41.

[0046] The mirror seat lock core A41 in the embodiment is provided with a locking clamping groove A47, and the locking clamping groove A47 is provided with a locking clamping block A410. When the mirror seat lock core A41 is pressed to make the locking clamping block A410 disengage from the intervertebral disc mirror device B, the distance adjustment of the intervertebral disc mirror device B relative to the fixing device A can be realized. When the mirror seat lock core A41 is released, the locking clamping block A410 can be clamped with the intervertebral disc mirror device B under the action of the unlocking block spring A45, so as to fix the intervertebral disc mirror device B relative to the fixing device A.

[0047] In this embodiment, the unlocking block A42 is provided with an unlocking surface A411. When the unlocking block A42 is rotated so that the unlocking surface A411 contacts the side wall of the unlocking slot A48, the unlocking block spring A45 is in a compressed state, which keeps the unlocking block A42 in the unlocked state. This allows for pitchless adjustment of the intervertebral disc endoscope device B (e.g., Figure 8 (As shown); Conversely, when the unlocking block A42 is rotated, causing the unlocking surface A411 to disengage from the side wall of the unlocking slot A48, the unlocking block spring A45 is in the unfolded state. In this state, pressing the endoscope base lock cylinder A41 causes the locking block A410 to disengage from the intervertebral disc endoscope device B, allowing for distance adjustment of the intervertebral disc endoscope device B relative to the fixing device A. In this state, releasing the endoscope base lock cylinder A41 causes the locking block A410 to engage with the intervertebral disc endoscope device B under the action of the unlocking block spring A45, thus fixing the intervertebral disc endoscope device B relative to the fixing device A. This allows for pitch adjustment of the intervertebral disc endoscope device B (e.g., Figure 9 (As shown).

[0048] The discoscope device B in this embodiment includes a discoscope body B1, a flushing connector B2, an external endoscope tube B3, and an internal endoscope tube B4. The flushing connector B2, the external endoscope tube B3, and the internal endoscope tube B4 are all mounted on the discoscope body B1. The external endoscope tube B3 is fitted over the internal endoscope tube B4, and a flushing channel is formed between the outer wall of the internal endoscope tube B4 and the inner wall of the external endoscope tube B3. This flushing channel is connected to the flushing connector B2.

[0049] In this embodiment, the external endoscope tube B3 and the internal endoscope tube B4 form the endoscope tube, which is inserted into the sleeve A11. The locking rod B5 is inserted into the locking hole provided in the endoscope base body A23. The intervertebral disc endoscope body B1 is provided with the locking rod B5, and the locking rod B5 is provided with the locking groove B6. The locking groove B6 cooperates with the locking block A410. There are multiple locking grooves B6, and the multiple locking grooves B6 are arranged at equal intervals. That is to say, with pitch adjustment, the locking block A410 will be locked into the locking groove B6 for fixation, while without pitch adjustment, it means that there is no need to position the intervertebral disc endoscope device B, and the intervertebral disc endoscope device B can freely extend and retract within the fixing device A.

[0050] Specifically, the sleeve A11 and sleeve fixing frame A12 of the medical adjustable intervertebral disc mirror with fixing device are welded, the mirror seat fixing block A21 and sleeve fixing frame A12 are connected by screws and positioning pins, the mirror seat fixing block A21 has a mirror seat rotating block A22 connected with a mirror seat main body A23 inside, the mirror seat rotating block A22 is positioned and fixed by rotating block spring A32 and rotating block lock core A31, pressing the rotating block lock core A31 can realize the rotation of the mirror seat rotating block A22 to the left or to the right; rotating the unlocking block handle A44 to the right can drive the unlocking block A42 to unlock the mirror seat lock core A41 to realize the non-pitch forward and backward adjustment of the intervertebral disc mirror, rotating the unlocking block handle A44 to the left can drive the unlocking block A42 to restore the locking function of the mirror seat lock core A41, and realize the pitch forward and backward adjustment of the intervertebral disc mirror device B according to a certain pitch.

[0051] In addition, it should be noted that the specific embodiments described in the specification, the shape of the zero, the components, the name taken, etc. can be different, the above described in the specification is only an example of the structure of the present application. Any equivalent changes or simple changes made according to the structure, features and principles described in the patent concept of the present application are included in the protection scope of the present application. Those skilled in the art can make various modifications or supplements or use similar ways to replace the described specific embodiments, as long as they do not deviate from the structure of the present application or exceed the scope defined by the present claims, which shall belong to the protection scope of the present application.
