The devices can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein can similarly be interpreted accordingly.

[0025] As shown in Figures 1 to 7 The embodiment of the application provides a lumbar facet joint intraosseous injection puncture device which comprises a body surface positioning frame 1 and an extracorporeal positioning frame 2, the body surface positioning frame 1 and the extracorporeal positioning frame 2 are fixedly connected together through a cooperative rod 3, and the top and bottom of the body surface positioning frame 1 are both provided with a positioning bandage 4; the positioning bandage 4 is a magic tape bandage, medical staff can fix the body surface positioning frame 1 at the lumbar position of a patient by means of the positioning bandage 4; in the technical solution, the working principle that the positioning bandage 4 is bound on the body of the patient is disclosed as prior art, and thus is not described herein.

[0026] A cooperative puncture mechanism is used for assisting medical staff in puncture operation, and the cooperative puncture mechanism is connected with the body surface positioning frame 1, the extracorporeal positioning frame 2 and the cooperative rod 3 respectively; the cooperative puncture mechanism comprises movable joints 5 installed on the body surface positioning frame 1 and the extracorporeal positioning frame 2; the body surface positioning frame 1 and the extracorporeal positioning frame 2 are both rectangular profiles; the movable joints 5 are arranged on two long edges of the rectangular profiles of the body surface positioning frame 1 and the extracorporeal positioning frame 2; the two ends of the cooperative rod 3 are fixed with the movable joints 5 on the body surface positioning frame 1 and the extracorporeal positioning frame 2 respectively; and the movable joints 5 are limited and rotationally connected together.

[0027] In the above structure, since several movable joints 5 are arranged on two long sides of the rectangular profile of the body surface positioning frame 1 and the body external positioning frame 2, and adjacent two movable joints 5 can rotate relative to each other, the overall profile of the body surface positioning frame 1 and the body external positioning frame 2 can be bent at the positions of the movable joints 5. When the medical staff fixes the body surface positioning frame 1 at the lumbar vertebrae position of the patient by means of the positioning bandage 4, the overall profile of the body surface positioning frame 1 will be bent according to the profile of the lumbar vertebrae of the patient, and the several movable joints 5 will also rotate synchronously during the bending of the body surface positioning frame 1, so that the profile of the body surface positioning frame 1 is consistent with the profile of the lumbar vertebrae of the patient.

[0028] Further, since the two ends of the cooperative rod 3 are fixed with the movable joints 5 on the body surface positioning frame 1 and the body external positioning frame 2 respectively, when the body surface positioning frame 1 is bent, the body external positioning frame 2 will also be bent synchronously with the body surface positioning frame 1 under the pulling action of the cooperative rod 3, and the bending radii of the body surface positioning frame 1 and the body external positioning frame 2 are completely consistent.

[0029] In the embodiment, as shown in Figures 1 to 7 The bottom end of the movable joint 5 is fixedly connected with the first limiting block 6 and the second limiting block 7, and the top end of the movable joint 5 is provided with a groove body matched with the profile of the first limiting block 6 and the second limiting block 7. Adjacent two movable joints 5 are connected together by the first limiting block 6, the second limiting block 7 and the groove body matched with the profile of the first limiting block 6 and the second limiting block 7. The inner wall of the movable joint 5 installed on the body surface positioning frame 1 is fixedly connected with the third limiting block 8, the third limiting block 8 is inserted with the steel wire 9, one end of the steel wire 9 is fixed with the movable joint 5 located at the top of the body surface positioning frame 1, and the other end of the steel wire 9 is extended to the outside of the body surface positioning frame 1 from the bottom of the body surface positioning frame 1. The bottom outer wall of the body surface positioning frame 1 is symmetrically provided with the binding rod 10, and the binding rod 10 has an "L" shaped profile.

[0030] As described above, two adjacent movable joints 5 can rotate relative to each other, specifically, the two adjacent movable joints 5 are limited to rotate by the first limiting block 6, the second limiting block 7 and the groove body matching the profile of the first limiting block 6 and the second limiting block 7. Since the size of the groove body is slightly larger than the size of the first limiting block 6 and the second limiting block 7, and the overall profile of the movable joint 5 is cylindrical, the first limiting block 6 and the second limiting block 7 can rotate a small distance in the groove body matching the profile thereof. The distance depends on the size difference between the groove body and the first limiting block 6 and the second limiting block 7. The first limiting block 6 has a circular profile, and the second limiting block 7 has an "L" shaped profile. When the two adjacent movable joints 5 rotate relative to each other, the first limiting block 6 rotates around the center of the circle as the pivot. During the rotation of the movable joint 5, the second limiting block 7 limits the rotation by the "L" shaped profile, thereby preventing the movable joint 5 from being misaligned or disconnected. Since the body surface positioning frame 1 and the external positioning frame 2 are provided with a plurality of movable joints 5, when the plurality of movable joints 5 are connected together, the body surface positioning frame 1 and the external positioning frame 2 can be bent to a large curvature, thereby matching the overall profile of the body surface positioning frame 1 to the profile of the patient's lumbar vertebrae.

[0031] Further, the inner wall of the movable joint 5 mounted on the body surface positioning frame 1 is provided with a steel wire 9, which is limited in the movable joint 5 by the third limiting block 8. The third limiting block 8 is mounted on the same side as the second limiting block 7. Since one end of the steel wire 9 is fixed to the movable joint 5 at the top of the body surface positioning frame 1, and the other end of the steel wire 9 is pulled out from the bottom of the body surface positioning frame 1, when the medical staff pulls down the steel wire 9, each movable joint 5 will rotate synchronously under the pulling action of the steel wire 9, thereby causing the body surface positioning frame 1 to bend. When the body surface positioning frame 1 is bent to a suitable curvature, the medical staff can wind the steel wire 9 on the two binding rods 10. Since the binding rod 10 has an "L" shaped profile, the medical staff can first wind the steel wire 9 horizontally on the two binding rods 10, and then wind the tail of the steel wire 9 vertically on any one of the binding rods 10, thereby completing the fixation of the steel wire 9. Since the steel wire 9 has a certain plasticity, the steel wire 9 will not be disconnected after being wound on the binding rod 10. When the end of the steel wire 9 is fixed by winding, the movable joints 5 on the body surface positioning frame 1 are tightly connected to each other and cannot continue to rotate, so the overall profile of the body surface positioning frame 1 is also fixed and cannot continue to bend.

[0032] Further, when the overall profile of the body surface positioning frame 1 is fixed, the profile of the external positioning frame 2 will match the profile of the body surface positioning frame 1 under the connection of the cooperation rod 3, and also be fixed. At this time, the body surface positioning frame 1 and the external positioning frame 2 form a stable support system, and the bending curvature of the support system matches the bending curvature of the patient's lumbar vertebrae.

[0033] As one implementation method in this embodiment, such as Figure 4 , Figure 8 and Figure 9 As shown, the collaborative puncture mechanism also includes a puncture positioning plate 14 installed between the body surface positioning frame 1 and the external positioning frame 2. The top and bottom of the puncture positioning plate 14 are fixedly connected to a first bow-shaped plate 11, and the two ends of the first bow-shaped plate 11 are fixedly connected to a second bow-shaped plate 12. A puncture positioning cylinder 15 is fixedly connected at the middle position of the puncture positioning plate 14. The first bow-shaped plate 11 and the second bow-shaped plate 12 are both concave and bent toward the center position of the puncture positioning plate 14. The two ends of the second bow-shaped plate 12 are fixedly connected to a bending part 13. The first bow-shaped plate 11, the second bow-shaped plate 12, the bending part 13 and the puncture positioning plate 14 are integrally formed structures. The bending part 13 has a hook-like outline. The second bow-shaped plate 12 and the collaborative rod 3 are fixed together by the bending part 13. A puncture positioning ball 16 is rotatably connected inside the puncture positioning cylinder 15. An adjustment knob 17 is screwed onto the outer wall of the puncture positioning cylinder 15. The puncture needle is inserted into the puncture positioning ball 16.

[0034] In the above structure, the puncture positioning plate 14 is installed between the two first bow-shaped plates 11. Because the first bow-shaped plates 11 bend towards the puncture positioning plate 14, both ends of the first bow-shaped plates 11 have an outward elastic tendency. The second bow-shaped plates 12 are installed at both ends of the first bow-shaped plates 11. Because the second bow-shaped plates 12 bend towards the puncture positioning plate 14, both ends of the second bow-shaped plates 12 have an outward elastic tendency. With this arrangement, when medical personnel press the ends of the first bow-shaped plates 11, the ends of the first bow-shaped plates 11 will tilt outward. When the ends of the first bow-shaped plates 11 tilt outward, the ends of the second bow-shaped plates 12 will tilt outward simultaneously under the pulling force of the first bow-shaped plates 11. This allows the second bow-shaped plates 12 to be engaged with the coordinating rod 3 via the bending portion 13, and the bending portion 13 is fixed to the coordinating rod 3 by the elastic tendency of the first and second bow-shaped plates 11. On rod 3, since several cooperating rods 3 are set between the surface positioning frame 1 and the external positioning frame 2, medical personnel can adjust the snap-fit ​​position of the bending part 13 as needed, thereby adjusting the position of the puncture positioning plate 14 between the surface positioning frame 1 and the external positioning frame 2. During the position adjustment process, the puncture positioning plate 14 completely follows the contours of the surface positioning frame 1 and the external positioning frame 2. Since the puncture positioning plate 14 is installed in the middle position of the first arched plate 11, and the first arched plate 11, the second arched plate 12, the bending part 13 and the puncture positioning plate 14 are integrally formed structures, when the two ends of the first arched plate 11 and the two ends of the second arched plate 12 undergo elastic deformation, the overall structural contour of the puncture positioning plate 14 is not affected. This setting is not only simple in structure, but also ensures that the shape of the puncture positioning plate 14 will not be affected when the first arched plate 11 and the second arched plate 12 deform.

[0035] Furthermore, the puncture needle is inserted into the puncture positioning ball 16. The puncture positioning ball 16 can not only rotate freely within the puncture positioning cylinder 15 to adjust the angle, but can also be fixed by screwing on the adjustment knob 17. This setting allows the puncture angle of the puncture needle to be adjusted by the puncture positioning ball 16, and the puncture position of the puncture needle to be adjusted by the first arch plate 11 and the second arch plate 12. Moreover, during the adjustment of the puncture position, the puncture needle is always ensured to move along the contour of the patient's lumbar spine. This setting not only makes it easier for medical personnel to find the "joint gap" of the lumbar facet joints, but also allows them to determine the puncture angle and puncture depth based on the contour of the patient's lumbar spine, greatly reducing the difficulty of the puncture operation and improving the efficiency of the puncture operation.

[0036] The working principle of the technical solution provided by this invention is as follows: In use, medical personnel first use positioning straps 4 to fix the top of the surface positioning frame 1 above the patient's lumbar spine. Then, according to the contour of the patient's lumbar spine, they pull the steel wire 9 downwards. Under the pulling action of the steel wire 9, each movable joint 5 will rotate synchronously, causing the surface positioning frame 1 to bend. When the surface positioning frame 1 bends to the same arc as the contour of the patient's lumbar spine, the medical personnel first wrap the steel wire 9 horizontally around the two binding rods 10, and then let the tail of the steel wire 9 be wrapped vertically around any binding rod 10 to complete the fixation of the steel wire 9. After the steel wire 9 is fixed, the medical personnel use positioning straps 4 again to fix the bottom of the surface positioning frame 1 below the patient's lumbar spine. At this time, the movable joints 5 on the surface positioning frame 1 are tightened together and cannot continue to rotate. The overall contour of the surface positioning frame 1 is also fixed at the position of the patient's lumbar spine and cannot bend further.

[0037] After the surface positioning frame 1 is fixed, under the connecting action of the coordinating rod 3, the external positioning frame 2 has the same curvature as the surface positioning frame 1 and is also fixed. At this time, the surface positioning frame 1 and the external positioning frame 2 form a stable support system, and the curvature of this support system is consistent with the curvature of the patient's lumbar spine. Then, the medical staff presses the two ends of the first arched plate 11. Under the pressure, the two ends of the first arched plate 11 will tilt outward. When the two ends of the first arched plate 11 tilt outward, the two ends of the second arched plate 12 will tilt outward synchronously under the tension of the first arched plate 11. The second bow-shaped plate 12 is raised so that it can be engaged with the coordinating rod 3 by means of the bending part 13, and the bending part 13 is fixed to the coordinating rod 3 by means of the elastic tendency of the first bow-shaped plate 11 and the second bow-shaped plate 12. Since several coordinating rods 3 are set between the body surface positioning frame 1 and the external positioning frame 2, medical personnel can adjust the engagement position of the bending part 13 as needed, thereby adjusting the position of the puncture positioning plate 14 between the body surface positioning frame 1 and the external positioning frame 2. During the position adjustment process, the puncture positioning plate 14 completely follows the contour of the body surface positioning frame 1 and the external positioning frame 2.

[0038] After the position of the puncture positioning plate 14 is adjusted, the medical staff inserts the puncture needle into the puncture positioning ball 16 and rotates the puncture positioning ball 16 to change the puncture angle of the puncture needle. Once the puncture angle is determined, the medical staff tightens the adjustment knob 17 to fix the puncture positioning ball 16, and then the puncture needle can be advanced for puncture. This setting not only makes it easier for medical staff to find the "joint gap" of the lumbar facet joints, but also allows them to determine the puncture angle and puncture depth based on the patient's lumbar spine contour, greatly reducing the difficulty of the puncture operation and improving the efficiency of the puncture operation.

[0039] This invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this invention. To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0040] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
