Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically a visualization device for vertebral osteoporotic fractures. Background Technology

[0002] With the increasing aging of the global population, the incidence of osteoporotic vertebral fractures is rising year by year, becoming a common orthopedic disease affecting the quality of life of the elderly. Patients with these fractures often experience bone loss and vertebral structural fragility, requiring bone cement injection to restore vertebral stability and relieve pain during clinical treatment. To ensure precise bone cement filling and reduce complications, visualization and auxiliary cleaning devices within the vertebral body have become crucial equipment during surgery. Their performance directly affects surgical outcomes and postoperative recovery, making the optimization and upgrading of these devices increasingly urgent.

[0003] While current intravertebral devices used in clinical practice have initially achieved basic functions such as vertebral body dislocation and endoscopic observation, their overall design still has limitations. Existing devices mostly employ a single-piece airbag support structure, and the visualization channel is often fixed. Furthermore, debris removal largely relies on simple liquid flushing methods. Although these designs can meet basic surgical needs, they have not yet developed more clinically relevant solutions in terms of adapting to different fracture morphologies, improving cleaning precision, and optimizing observation flexibility, making it difficult to fully cope with the complex intravertebral environment.

[0004] The existing surgical procedure involves first inserting the main body of the device into a designated location within the vertebral body, then activating the airbag structure to open up the collapsed vertebral body and restore its normal height; subsequently, an endoscope is inserted through a fixed channel on the device to observe the fracture and distribution of impurities within the vertebral body.

[0005] Existing technologies lack liquid guiding and adsorption structures, resulting in incomplete impurity removal, inconvenient visualization operations, fixed endoscope channels, and angle adjustments requiring overall device movement, which is not only cumbersome to operate but also leads to poor observation results.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The embodiments of the present invention will now be described.

[0039] Visualization device within the vertebral body for osteoporotic vertebral fractures, such as Figure 1-2 As shown, it includes a first outer shell 1, a driving device is provided inside the first outer shell 1, one end of the first outer shell 1 is connected to a second outer shell 2, and the end of the second outer shell 2 away from the first outer shell 1 is connected to a cleaning device.

[0040] For details, please refer to Figure 2-5 The cleaning device includes four fluid-changing airbags 10, which are arranged in a ring. The two ends of each airbag 10 are fixed by a collar 11 and a connecting ring 9. The connecting ring 9 is connected to the second outer shell 2, and the connecting ring 9 and collar 11 limit the movement of the four airbags 10. The cleaning device also includes a fluid-guiding groove 22, which is located on the outer surface of the airbag 10. Several fluid-guiding tubes 30 are arranged inside the airbag 10 in conjunction with the fluid-guiding groove 22. Each fluid-guiding tube 30 is divided into two parts. A portion of the liquid guide tube 30 near the collar 11 is U-shaped, with its two ends connected to two loops within the liquid guide groove 22. The portion of the liquid guide tube 30 near the connecting ring 9 of the fluid exchange airbag 10 is configured as two sections, one long and one short, corresponding to the other portion near the collar 11. These two sections are also connected to two loops within the liquid guide groove 22. The two portions of the liquid guide tube 30 form a complete loop. A water inlet pipe 40 and a water outlet pipe 41 are respectively provided within the connecting ring 9 to accommodate the two sections of the liquid guide tube 30. The water inlet pipe 40 and the water outlet pipe 41 extend through the second outer shell 2 to the first... Inside the outer casing 1, a water outlet 39 is provided on the first outer casing 1 in conjunction with a water outlet pipe 41, and a water inlet 5 is provided on the first outer casing 1 in conjunction with a water inlet pipe 40. In actual use, by connecting the water outlet pipe 41 and the water outlet 39 to a water source and a water pump respectively, the water source enters through the water inlet 5, flows along the water inlet pipe 40, and then enters the liquid guiding groove 22. The cleaning device in this application is mainly for cleaning small particle residues and secretions after fractures, and the required water flow does not need to be large. Therefore, this application utilizes the liquid guiding groove 22 combined with the adsorption force of the liquid itself to make the liquid... The fluid flows slowly within the drainage groove 22, adsorbing the liquid and fragmented impurities within the vertebral fracture site. The liquid then enters the drainage groove 22 and is slowly drawn out of the box device via the outlet 39 and the outlet pipe 41, carrying the adsorbed impurities out of the fracture site, thereby maintaining a good "bone cement" injection filling effect. The two-section drainage pipe 30 improves the efficiency of liquid flow and indirectly increases the stroke of the drainage groove 22, increasing the cleaning volume. In actual use, after maintaining a cleaning period, the water supply can be disconnected to maintain the extraction state and drain the excess liquid from the vertebra.

[0041] In conjunction with the above structure, the cleaning device also includes a mounting groove 28, which is located at one end of the fluid-changing airbag 10 near the second outer shell 2. A retaining plate 12 is provided inside the second outer shell 2 to match the mounting groove 28. One end of the retaining plate 12 away from the fluid-changing airbag 10 is connected to a guide plate 13, and the other end of the guide plate 13 is connected to a driving device. A connecting pipe 14 is provided at one end of the guide plate 13 near the driving device. An air vent 3 is provided on the first outer shell 1 to match the connecting pipe 14, and the air vent 3 is connected to the connecting pipe 14 via a flexible hose. The driving device controls the retaining plate 12 to enter the mounting groove 28 to support the fluid-changing airbag 10.

[0042] Specifically, the driving device includes a fixing plate 6, which is disposed at the end of the first outer shell 1 away from the second outer shell 2. The fixing plate 6 is fixedly connected to the first outer shell 1. Inside the first outer shell 1, four air pumps 16 are disposed on the fixing plate 6 in conjunction with four guide plates 13. The end of the air pump 16 near the guide plate 13 is movably connected to a telescopic rod 15. The telescopic rod 15 is fixedly connected to the guide plate 13. The four air pumps 16 control the four telescopic rods 15 respectively, thereby separately supporting the four clamping plates 12 for their corresponding fluid replacement airbags 10. It cooperates with the structure in the mounting groove 28 to control the inflation of the fluid replacement airbags 10.

[0043] refer to Figure 8-9Specifically, both the guide plate 13 and the clamping plate 12 are hollow structures. A partition 29 is provided inside the guide plate 13, and the clamping plate 12 is connected to the partition 29. A second connecting port 38 is provided on the partition 29, and a first connecting port 37 is provided on the clamping plate 12. A connecting structure is provided within the mounting groove 28 to cooperate with the clamping plate 12. The connecting structure includes a positioning block 35, which is fixedly installed within the mounting groove 28. A connecting rod 34 is movably installed within the mounting groove 28. The connecting rod 34 is hollow. 4. One end of the connecting rod 34 is provided with a through hole in the clamping plate 12. The other end of the connecting rod 34 extends through the positioning block 35 to the outside of the fluid replacement airbag 10. The end of the connecting rod 34 connected to the outside of the fluid replacement airbag 10 is connected to the top block 32. The outside of the fluid replacement airbag 10 is provided with a reset rubber sleeve 31 in conjunction with the top block 32. A pair of air outlet ports 33 are provided on the connecting rod 34. A pair of vent ports 36 are provided in the mounting groove 28 in conjunction with the pair of air outlet ports 33. An exhaust port 44 is provided in the fluid replacement airbag 10 in conjunction with the air outlet ports 33. The vent ports 36 are connected to the inside of the fluid replacement airbag 10. With this configuration, when gas is introduced into the vent 3, the gas enters the guide plate 13. Due to the second connecting port 38 on the partition 29, both sides of the partition 29 within the guide plate 13 are filled with gas. Then, the gas enters the retaining plate 12 through the first connecting port 37, filling the retaining plate 12 with gas. Once the retaining plate 12 is fully inserted into the mounting groove 28, it compresses the connecting rod 34, causing the air outlet 33 on the connecting rod 34 to align with a pair of vents 36. This allows the gas in the retaining plate 12 to enter the fluid exchange airbag 10, thereby inflating the fluid exchange airbag 10. The effect is that when the control air pump 16 is reset, under the action of the reset rubber sleeve 31, when it resets itself, it will cause the top block 32 to reset, thereby causing the air outlet 33 and the air inlet 36 to lose their overlap, and then make them overlap with the exhaust port 44 for air release and reset. In actual use, by connecting the air exchange ports 3 of the four different guide plates 13 to the corresponding external devices, air is injected into the device according to the different inflation requirements of the four different liquid exchange airbags 10, controlling the expansion of the liquid exchange airbags 10, and simultaneously cooperating with the air pump 16 to push the corresponding card plate 12 into the designated mounting slot 28 to provide support.

[0044] When the fluid exchange airbag 10 is inflated, it means that the fluid guide groove 22 on the fluid exchange airbag 10 needs to contact the inner wall of the vertebra, so that the fluid flowing in the fluid guide groove 22 can better remove impurities and accumulated fluid in the vertebra. Similar to the traditional balloon, the operator can also start four air pumps 16 and connect four air exchange ports 3 at the same time, so that the four fluid exchange airbags 10 expand synchronously, thereby achieving the effect of the balloon to effectively support the fracture site of the vertebra, maintain the anterior expansion effect, and also clean the fracture site.

[0045] Based on the above structure, refer to Figure 6-7 A viewing device is movably arranged at the center of several of the fluid exchange airbags 10. The viewing device includes a turntable 23. A second opening 43 is opened at an eccentric position on the turntable 23. A connecting block 27 is provided at the end of the turntable 23 away from the second outer shell 2. Several second guide tubes 24 are arranged around the end of the connecting block 27 away from the turntable 23. The second guide tubes 24 are set outward at a certain angle. A first opening 25 is opened on the end of the connecting block 27 near the turntable 23 in conjunction with several second guide tubes 24. Several first openings 25 are arranged in conjunction with several second guide tubes 24. A rotating groove 26 is opened on the connecting block 27 in conjunction with the turntable 23. The turntable 23 is rotatably connected to the connecting block 27 through the rotating groove 26. The opening position of the first opening 25 is arranged in conjunction with the second opening 43. In this way, by rotating the turntable 23, the second opening 43 can be made to coincide with different first openings 25, so that the endoscope used for exploration can advance along different second guide tubes 24, thereby controlling the protrusion angle of the endoscope.

[0046] To cooperate with this, in order to control the angle and position of the turntable 23, the driving device also includes a guide cylinder 8. One end of the guide cylinder 8 is fixedly connected to the turntable 23, and the other end of the guide cylinder 8 passes through the fixing plate 6. The end of the guide cylinder 8 away from the turntable 23 is connected to a connecting plate 7. The guide cylinder 8 is arranged in a ring shape. A control motor 17 is arranged on the surface of the fixing plate 6 near the turntable 23. The output end of the control motor 17 is connected to a first transmission gear 18. A third transmission gear 21 is arranged on one side of the first transmission gear 18. The third transmission gear 21 is meshed with the inside of the guide cylinder 8. A second transmission gear 19 is arranged on the fixing plate 6 to cooperate with the third transmission gear 21. The second transmission gear 19 is rotatably connected to the fixing plate 6. The moving gear 21 and the second transmission gear 19 are connected by a transmission rod 20. With this configuration, by controlling the motor 17 to drive the first transmission gear 18 and then the third transmission gear 21 to rotate, the guide cylinder 8 can be rotated, and the turntable 23 at the other end of the guide cylinder 8 can be rotated synchronously. This controls the second opening 43 to coincide with the first opening 25, guiding the endoscope. Correspondingly, a first guide tube 4 is provided inside the guide cylinder 8 to match the second opening 43. One end of the first guide tube 4 is aligned with the second opening 43, and the other end of the first guide tube 4 extends through the guide cylinder 8 to the outside of the first outer shell 1. When the endoscope enters the device, it is guided by the first guide tube 4, pulling the endoscope to the second opening 43 so that it can quickly enter the opening.

[0047] refer to Figure 1The end of the guide cylinder 8 away from the turntable 23 is connected to a connecting plate 7. The first outer shell 1 is provided with a guide groove 42 in conjunction with the first guide tube 4. The design of the guide groove 42 satisfies the requirement that the guide cylinder 8 can be controlled by the connecting plate 7 to move a certain distance and the angle of rotation of the turntable 23.
