[0033] Figure 2 It is a schematic diagram of the positioning mechanism structure in Example 1 of the present invention.

[0034] like Figure 2 As shown, the positioning mechanism 10 includes: an upper right-angle guide member 11, a lower right-angle guide member 12, an upper slider 13, a lower slider 14, an upper positioning rod 15, a lower positioning rod 16, a clamping member 17, a right-angle perspective positioning ruler 18 and a fixing column 19.

[0035] The upper right-angle guide rail 11 comprises two upper guide rails perpendicular to each other, and the side of each upper guide rail is provided with a side perspective positioning ruler 111 with scale marks extending along the extension direction of the upper guide rail. The upper right-angle guide rail 11 is arranged parallel to the horizontal plane.

[0036] The lower right angle guide member 12 comprises two lower guide rails perpendicular to each other, and the lower right angle guide rails are arranged in parallel below the upper right angle guide rails, and when viewed from top to bottom, the upper right angle guide rails and the lower right angle guide rails completely overlap. The side of each lower guide rail is provided with a side perspective positioning ruler 111 with scale marks extending along the extension direction of the lower guide rail.

[0037] The fixing column 19 is arranged between the upper right angle guide member 11 and the lower right angle guide member 12. In this embodiment, there are three fixing columns 19, which are arranged at two ends of the upper right angle guide member 11 and at the connection between the two upper guide rails. The user can select fixing columns 19 of different heights according to actual conditions to control the distance between the upper right angle guide member 11 and the lower right angle guide member 12.

[0038] Figure 4 a is a front view of the upper slider in embodiment 1 of the present invention. Figure 4 b is a side view of the upper slider in embodiment 1 of the present invention.

[0039] like Figure 4 As shown in Figs. 4a and 4b, there are two upper sliders 13, which are respectively arranged on two upper guide rails. Each upper slider 13 has two slide grooves matching the upper guide rails and a through hole, and the axis of the through hole is perpendicular to the axis of the slide groove. A mark 131 is arranged on the outer surface of the upper slider 13 facing the side perspective positioning ruler 111, which is used to facilitate the user to read from the side perspective positioning ruler 111. Specifically, in this embodiment, the mark 131 is arranged along the line connecting the center of the through hole and the center point of the slide groove.

[0040] There are two lower sliders 14, which are respectively arranged on two lower guide rails. In this embodiment, the specific structure of the lower slider 14 is completely consistent with that of the upper slider 13, and will not be repeated here.

[0041] The number of upper positioning rods 15 is 2. The two upper positioning rods 15 are respectively arranged in the through holes of the two upper sliders 13. The two upper positioning rods 15 are perpendicular to each other. The ends of the two upper positioning rods 15 that are close to each other are both provided with a tapered threaded member.

[0042] The number of the lower positioning rods 16 is 2. The two lower positioning rods 16 are respectively inserted into the through holes of the two lower sliding blocks 14. The two lower positioning rods 16 are perpendicular to each other. The ends of the two lower positioning rods 16 that are close to each other are both provided with a tapered threaded member.

[0043] The clamping member 17 can be of various types. In this embodiment, both clamping members 17 are universal joint clamping members. The universal joint clamping member includes: a universal joint ball 171 , a joint ball sleeve 172 and three connecting columns 173 .

[0044] The universal joint ball 171 is arranged in the joint ball sleeve card 172 and can be universally rotated relative to the joint ball sleeve card. The universal joint ball 171 has a groove passing through the ball center, and the groove is used to clamp the puncture instrument (such as a puncture needle). Therefore, the universal joint ball 171 with different groove sizes can be selected according to actual needs.

[0045] The joint ball sleeve clamp 172 is sleeved on the outside of the universal joint ball 171 , and the plane where the joint ball sleeve clamp 172 is located is parallel to the plane where the right-angle perspective positioning ruler 18 is located.

[0046] There are three connecting posts 173, which are evenly distributed on the outer edge of the joint ball sleeve clamp 172. Each connecting post has a threaded hole on the top, which matches the tapered threaded member at the end of the upper positioning rod 15 or the lower positioning rod 16. When in use, the clamp 17 is threadedly connected to the upper positioning rod 15 or the lower positioning rod 16 by threading the two upper positioning rods 15 or the two lower positioning rods 16 with the two connecting posts 173 respectively, thereby realizing the threaded connection between the clamp 17 and the upper positioning rod 15 or the lower positioning rod 16.

[0047] The right-angle perspective positioning ruler 18 has scale marks, and its two sides are respectively parallel to the two guide rails of the upper right-angle guide rail member 11 . The right-angle perspective positioning ruler 18 is arranged on the inner side of the upper right-angle guide rail member 11 or on the inner side of the lower right-angle guide rail member 12 .

[0048] It is worth noting that the positioning mechanism 10 needs to be exposed to X-rays to work. Therefore, in order to smoothly realize its function, the upper right-angle guide rail 11, the lower right-angle guide rail 12, the upper slider 13, the lower slider 14, the upper positioning rod 15, the lower positioning rod 16, the clamping member 17, the right-angle perspective positioning ruler 18 and the fixed column 19 are all made of materials that do not show up on X-ray films. Only the scale marks of the side perspective positioning ruler 111 and the scale marks of the right-angle perspective positioning ruler 18 are made of materials that show up on X-ray films.

[0049] The coordinate adjustment mechanism 20 includes an adjustment block 21 , a horizontal rod 22 , a sleeve 23 , a movable sleeve rod 24 , a horizontal rod adjustment screw 25 , and a movable sleeve rod adjustment screw 26 .

[0050] The adjustment block 21 has a horizontal hole and a vertical hole.

[0051] The horizontal rod 22 is movably inserted into the horizontal hole of the adjustment block 21, and one end of the horizontal rod 22 abuts against the fixing column 19 located at one end of the upper right angle guide member 11 and the lower right angle guide member 12. The axis of the horizontal rod 22 and the axis of the movable sleeve rod 24 are perpendicular to each other.

[0052] The horizontal rod adjusting screw 25 is arranged on the adjusting block 21, and is used for tightening the horizontal rod adjusting screw 25 to fix the horizontal rod 22 on the adjusting block 21 after the horizontal rod 22 is adjusted to a suitable position, or for loosening the horizontal rod adjusting screw 25 when the horizontal rod 22 needs to be adjusted so that the horizontal rod 22 can move freely in the horizontal hole.

[0053] The bottom end of the sleeve 23 is disposed on the supporting mechanism 30 .

[0054] One end of the movable sleeve rod 24 is movably inserted into the sleeve 23, and the other end is fixed in the vertical hole of the adjustment block.

[0055] The movable sleeve rod adjusting screw 26 is arranged on the sleeve 23, and is used for tightening the movable sleeve rod adjusting screw 26 to fix the movable sleeve rod 24 on the sleeve 23 after the movable sleeve rod 24 is adjusted to a suitable position, or for loosening the movable sleeve rod adjusting screw 26 when the movable sleeve rod 24 needs to be adjusted so that the movable sleeve rod 24 can move freely in the vertical hole.

[0056] The supporting mechanism 30 includes a load-bearing plate 31 , a supporting plate 32 , a clamping plate 33 and a clamping plate adjusting screw 34 .

[0057] The upper surface of the load-bearing plate 31 is fixedly connected to the sleeve 23 , and the lower surface is fixedly connected to the upper surface of the support plate 32 .

[0058] The support plate 32 has a groove opening toward the side.

[0059] The clamping plate 33 is disposed in the groove of the support plate 32. The upper surface of the clamping plate 33 cooperates with the lower surface in the groove of the support plate 32 to clamp the plate-like object (such as a medical bed) so as to fix the support mechanism 30 on the plate-like object.

[0060] The clamping plate adjusting screw 34 is passed through the bottom of the support plate 32, and one end of the clamping plate 33 is fixedly connected to the clamping plate 33. The clamping plate adjusting screw 34 is used to adjust the position of the clamping plate 33 in the groove of the support plate 32, thereby adjusting the size of the space formed by the upper surface of the clamping plate 33 and the lower surface in the groove of the support plate 32 so that the support mechanism 30 can be better fixed.

[0061] Figure 5 It is a schematic diagram of the principle of positioning the puncture path by the dual-coordinate space positioning device in Example 1 of the present invention.

[0062] like Figure 5As shown, the principle of positioning the puncture path by the dual-coordinate space positioning device 100 provided in this embodiment is as follows: for two coordinate systems with the same Z axis in space, the puncture path φ (not parallel to the XY plane) intersects at two points in the XY plane and the X'Y' plane of the two coordinate systems. It is only necessary to determine the spatial coordinate points (X1, Y1) and (X′1, Y′1) of the two coordinates to determine the puncture path φ in space.

[0066] Step 2: The patient lies prone in a direction parallel to the long axis of the operating table, and the detachable dual-coordinate positioning device 100 is moved to a proper position next to the operating table.

The detachable dual-coordinate positioning device 100 is fixed to the bedside by the support member 30;

[0067] Step 3, perspective positioning, first use a C-arm machine to take a standard lateral film (the shooting direction is parallel to the direction of the coordinate ruler perpendicular to the long axis of the human body), plan the correct puncture route in the X-ray, the puncture route intersects at two points at the upper and lower layers of the lateral perspective positioning rulers, read the two-point scales Y1 and Y′1, use a C-arm machine to take a standard frontal film (the shooting direction is perpendicular to the operating table), plan the correct puncture route in the X-ray film, the puncture route intersects at two points at the vertical perspective positioning rulers that are perpendicular to each other, and read the coordinates (X1, Y1) and (X′1, Y′1) corresponding to the vertical perspective positioning ruler scales parallel to the long axis of the human body;

[0068] Step 4, positioning puncture, adjust the scale on the slider of the lower slide rail parallel to the long axis of the human body to the scale Y1, adjust the scale on the slider of the lower slide rail perpendicular to the long axis of the human body to the scale X1, adjust the scale on the slider of the upper slide rail parallel to the long axis of the human body to the scale Y′1, and adjust the scale on the slider of the upper slide rail perpendicular to the long axis of the human body to the scale X′1;

[0069] Step 5, surgical puncture, at this time, the two clamping members 17 determine a fixed spatial orientation, and the puncture needle passes through the clamping member 17 located at the upper part, and then through the clamping member 17 located at the lower part, and finally directly punctures through the skin to reach the puncture target point;

[0070] Step 6: After the puncture is successful, the puncture member is released from the clamping member 17, and the detachable dual-coordinate positioning device 100 is dismantled to perform subsequent surgical steps.

[0071] In addition to spinal transforaminal endoscopic puncture, the detachable dual-coordinate positioning device 100 provided in this embodiment can also be used in a series of other operations that require positioning puncture, such as pedicle screw implantation, vertebroplasty bone cement injection, epidural anesthesia, spinal tumor biopsy, abscess puncture, interventional puncture, particle implantation, etc.
