[0034] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0035] like Figures 1 to 3The bone hook coordinate mapping and positioning device suitable for spinal surgery includes a bearing rod 1, which is characterized in that the bearing rod 1 is connected to an adjusting rod 3 through an adjusting shaft 2. In this way, appropriate angle adjustment can be performed to fit the physiological curve of the human back, which is convenient for better mapping and positioning. At the same time, a number of guide devices are arranged on the outside of the bearing rod 1 and the adjusting rod 3 for mapping guidance. Specifically, the guide device includes a guide seat 4, and a bone power cutting groove 5 is arranged on the outside of the guide seat 4, which can be suitable for the installation of subsequent orthopedic power depth limiters. In addition, in order to facilitate proper positioning and guiding, a bone hook groove 6 is arranged in the guide seat 4, and a number of bone hook components 10 are arranged in the bone hook groove 6 through a mapping component 13. Therefore, the position of the bone hook component 10 can be adjusted according to the needs of the current surgical operation area to ensure that it has better mapping and positioning.

[0036] In combination with a preferred embodiment of the utility model, a connecting rod 7 is provided on the inner side of the bearing rod 1. In this way, the utility model can be stably connected to the Y-rail quick-change joint of the surgical robot. At the same time, in order to allow the guide seat 4 to achieve appropriate rotation adjustment to adapt to the physiological curve of the human body, the guide seat 4 is connected to the corresponding bearing rod 1 or the adjusting rod 3 through the connecting shaft 8. In addition, a locking bolt 9 for locking the connecting shaft 8 is provided at the corresponding position of the bearing rod 1 and the adjusting rod 3, and the bottom of the locking bolt 9 is connected to one end of the connecting shaft 8, and the other end of the connecting shaft 8 is connected to the corresponding guide seat 4. Thus, when it is in a suitable angle position, convenient locking can be achieved.

[0037] Further, the bone hook assembly 10 adopted by the utility model includes a bone hook body, and an anti-rotation folding structure 11 is provided at the upper end of the bone hook body, and the anti-rotation folding structure 11 abuts against the lower end of the guide seat 4. In this way, after the bone hook assembly 10 is installed in place, auxiliary positioning can be achieved to prevent it from rotating unnecessarily during use, which affects the mapping positioning. At the same time, a connecting column extends from the upper end of the anti-rotation folding structure 11, and the connecting column is connected to the mapping assembly 13 after being inserted into the bone hook groove 6. In this way, stable locking can be achieved to prevent the bone hook assembly 10 from being displaced unnecessarily in the bone hook groove 6 during use.

[0038] In addition, in order to better hook the inner surface of the bone, a hook structure 12 is provided at the lower end of the bone hook body. During use, the hook structure 12 contacts the inner surface of the bone to form an inner surface contact point, and the position of the inner surface contact point forms a mapping relationship with the position of the corresponding mapping nut. In addition, the hook structure 12 is blunt-headed to prevent the bone hook assembly 10 from puncturing the dura mater when it is inserted.

[0039] Considering the convenience of positioning and locking, the connecting column is provided with an external thread, and the mapping component 13 is a mapping nut. Furthermore, in order to adapt to the physiological curve distribution of the bone, a circular arc of concession can be provided in the middle section of the bone hook body. In this way, it can fit the shape of the bone without unnecessary obstruction, without affecting the clear mapping indication, and facilitate accurate positioning.

[0040] Further, the upper surface of the bone power cutting groove 5 is provided with a rough adaptation structure 14, which is a fine sawtooth structure. Of course, the rough adaptation structure 14 can also be other shapes, as long as it corresponds to the shape of the lower surface of the orthopedic power depth stopper. In this way, unnecessary movement of the orthopedic power depth stopper during use can be prevented.

[0041] At the same time, in order to achieve appropriate horizontal limit guidance, the bone hook groove 6 is a rectangular groove. In addition, in order to prevent the bone hook groove 6 from getting stuck during placement at the two extreme positions, an oblong groove can also be used to form the bone hook groove 6.

[0042] The working principle of the utility model is as follows:

[0043] The angles of the bearing rod 1 and the adjusting rod 3 are adjusted to fit the physiological curve of the back of the human body. At the same time, the angle of the guide device is adjusted to better achieve fine-tuning of the physiological curve.

[0044] After that, the hook structure 12 at the lower end of the bone hook assembly 10 is hooked out of the inner surface of the bone. After the final positioning is completed, the coordinates of the contact points between the bone hook assembly 10 and the bone surface are mapped by the corresponding mapping nut positions, so as to achieve accurate mapping positioning for subsequent operations.

[0045] It can be seen from the above text description and the accompanying drawings that the following advantages are achieved after adopting the utility model:

[0046] 1. The angles of the load-bearing rod and the adjustment rod can be adjusted appropriately to fit the physiological curve of the human back and avoid subsequent positioning errors.

[0047] 2. The angle of the guide device itself can also be adjusted to provide a suitable angle according to mapping needs.

[0048] 3. The guide device can achieve stable positioning of the subsequently installed orthopedic dynamic depth limiter without sliding.

[0049] 4. The bone hook component can achieve accurate mapping of the bone surface contact point coordinates to improve operation accuracy.

[0050] 5. The bone hook assembly can be well positioned and will not rotate during use, and the hook structure will not puncture the dura mater.

[0051] 6. The overall structure is simple and can be adapted to various conventional surgical robots for quick disassembly and installation.

[0052] In addition, the indicated orientations or positional relationships described in the present invention are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or structure referred to must have a specific orientation or be operated with a specific orientation structure. Therefore, they cannot be understood as a limitation on the present invention.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
