Description

Technical Field

[0001] This invention relates to the field of medical auxiliary equipment technology, and in particular to a bone interface treatment tool for vertebroplasty in Kumell's disease. Background Technology

[0002] Percutaneous vertebroplasty is currently the mainstream surgical procedure for treating Kumell's disease of the thoracolumbar spine. The vertebral body in thoracolumbar Kumell's disease often contains liquefaction and cystic cavities, and the smooth interface makes it difficult for bone cement to anchor. The solution is to use tools to scrape away the cyst wall, necrotic bone, and other devitalized tissues to roughen the bone-cement interface, thereby increasing the anchoring strength of the bone cement. Simultaneously, it is necessary to consider the ability to insert a vertebroplasty needle through a channel (diameter <4mm, length 20cm). However, in clinical practice, the lack of specialized tools for processing the bone-cement interface within the vertebral body during surgery easily leads to poor bone cement anchoring effect, further resulting in poor surgical outcomes, unsatisfactory clinical efficacy, and unsatisfactory postoperative pain relief. Therefore, clinically, there is a need for specialized scraping tools for vertebroplasty of thoracolumbar Kumell's disease to help surgeons solve the problem of bone cement anchoring strength during vertebroplasty, leading to more satisfactory surgical results. Summary of the Invention

[0003] The purpose of this invention is to provide a bone interface treatment tool in vertebroplasty for Kumell's disease to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a bone interface treatment tool for vertebroplasty in Kumell's disease, comprising a protective shell, a wireless control mechanism fixedly connected to one side of the protective shell, an angle adjustment mechanism provided at the top of the protective shell, a support mechanism fixedly connected to the bottom of the protective shell, and a monitoring mechanism provided at one end of the angle adjustment mechanism.

[0005] Preferably, the support mechanism includes a fixed plate seat installed at the bottom of the protective shell, a plurality of movable hinge seats fixedly connected to the bottom side of the fixed plate seat, a threaded handle threaded through one side of each movable hinge seat, a first leg movably connected to the bottom of the movable hinge seat, a fixed sleeve fixedly installed at the bottom of the first leg, a second leg threaded through the bottom of the fixed sleeve, a fixing screw threaded through one side of the fixed sleeve, and a support fixedly connected to one end of the second leg.

[0006] Preferably, the wireless control mechanism includes a fixing plate fixedly connected to the top of the protective housing, a wireless signal receiving module fixedly connected to the top of the fixing plate, a signal transmission module disposed on one side of the wireless signal receiving module, a controller disposed on one side of the signal transmission module, a data storage module disposed on one side of the controller, and a data analysis module disposed on one side of the data storage module.

[0007] Preferably, the angle adjustment mechanism includes a drive motor fixedly connected to the top of the protective housing, a rotating disk fixedly connected to the transmission end of the drive motor, a small hinge seat movably connected to one side of the top of the rotating disk, an electric telescopic rod movably connected to one side of the small hinge seat, several guide rods fixedly connected to the top of the rotating disk, a device seat sleeved on the outer side of the guide rods, a hydraulic telescopic rod provided in the middle of the device seat, a device fixing platform movably connected to the top of the hydraulic telescopic rod, and the bottom end of the device fixing platform movably connected to the telescopic end of the electric telescopic rod.

[0008] Preferably, the monitoring mechanism includes a small electric telescopic rod fixedly connected to one side of the device fixing platform, a pressure detector is provided at one end of the small electric telescopic rod, an alarm is fixedly connected to one side of the pressure detector, a medical imaging wire is inserted through the inner wall of the gastric tube, and a scraper is provided at one end of the small electric telescopic rod.

[0009] Compared with the prior art, the beneficial effects of this invention are as follows: During liquefaction and cystic cavity treatment, the smooth interface allows for bone cement anchoring. The rotation of the drive motor drives the rotating disk to adjust the angle, thereby roughening the bone-cement interface and increasing the anchoring strength of the bone cement during scraping away cyst walls, dead bone, and other devitalized tissues. This facilitates treatment. A small hinge seat, in conjunction with the extension and retraction of the electric telescopic rod, allows for angle adjustment of the fixed platform of the drive device, thereby adjusting the electrodes and scraper for use.

[0010] The tool scrapes away the cyst wall, dead bone, and other devitalized tissues to roughen the bone-cement interface, thereby increasing the anchoring strength of the bone cement. At the same time, it is necessary to consider the insertion through the vertebral body shaping puncture needle channel. In order to facilitate pressure detection, a pressure detector is set up for easy control and detection. The pressure detector is extended and retracted by the extension and retraction of a small electric telescopic rod, which can also push the scraper to scrape away the cyst wall and dead bone. An alarm is set up to alert if the pressure is too high. Attached Figure Description

For example, they can refer to a fixed connection or configuration, a detachable connection or configuration, or an integral connection or configuration. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0017] like Figures 1-6 As shown, the present invention proposes a bone interface treatment tool for vertebroplasty in Kumell's disease, which includes a protective shell 1, a wireless control mechanism 4 fixedly connected to one side of the protective shell 1, an angle adjustment mechanism 5 provided on the top of the protective shell 1, a support mechanism 2 fixedly connected to the bottom of the protective shell 1, and a monitoring mechanism 3 provided at one end of the angle adjustment mechanism 5.

[0018] The support mechanism 2 includes a fixed plate seat 201 installed at the bottom of the protective shell 1. Several movable hinge seats 202 are fixedly connected to the bottom side of the fixed plate seat 201. A threaded handle 203 is threaded through one side of each movable hinge seat 202. A first support leg 204 is movably connected to the bottom of the movable hinge seat 202. A fixed sleeve 205 is fixedly installed at the bottom of the first support leg 204. A second support leg 206 is threaded through the bottom of the fixed sleeve 205. A fixing screw 207 is threaded through one side of the fixed sleeve 205. A support 208 is fixedly connected to one end of the second support leg 206.

[0019] In practical use, when scraping away necrotic tissue such as the capsule wall and dead bone, a movable hinge seat 202 fixed to the side of the fixed plate seat 201 facilitates the movable connection of the first leg 204 to ensure stability during equipment use. When adjusting the angle of the first leg 204, a threaded handle 203 is used to fix the first leg 204 to facilitate the removal of necrotic tissue such as the capsule wall and dead bone. The second leg 206 is stretched by a fixing sleeve 205 at one end of the first leg 204 and fixed by a fixing screw 207. The second leg 206 is supported and fixed by a support 208 at one end of the second leg 206.

[0020] The wireless control mechanism 4 includes a fixing plate 401 fixedly connected to the top of the protective housing 1, a wireless signal receiving module 402 fixedly connected to the top of the fixing plate 401, a signal transmission module 403 disposed on one side of the wireless signal receiving module 402, a controller 404 disposed on one side of the signal transmission module 403, a data storage module 405 disposed on one side of the controller 404, and a data analysis module 406 disposed on one side of the data storage module 405.

[0021] In practical use, the wireless signal receiving module 402 and signal transmission module 403 on the mounting plate 401 facilitate the transmission or reception of signals from the bone interface during vertebroplasty for Kumell's disease. The controller 404 controls and analyzes the bone interface data during vertebroplasty for Kumell's disease, and the data storage module 405 analyzes and processes the data.

[0022] In practical use, the external observation pressure detector 302 connected to the bone interface treatment in the Kumell vertebroplasty is then observed to monitor the pressure changes at the bone interface treatment site during the Kumell vertebroplasty. This helps to avoid insufficient or excessive pressure. When the pressure is insufficient, there is no sound; when the pressure is too high, the alarm 303 will sound an alarm.

[0023] The angle adjustment mechanism 5 includes a drive motor 501 fixedly connected to the top of the protective housing 1. A rotating disk 502 is fixedly connected to the transmission end of the drive motor 501. A small hinge seat 503 is movably connected to one side of the top of the rotating disk 502. An electric telescopic rod 504 is movably connected to one side of the small hinge seat 503. Several guide rods 505 are fixedly connected to the top of the rotating disk 502. A device seat 506 is sleeved on the outer side of the guide rods 505. A hydraulic telescopic rod 507 is provided in the middle of the device seat 506. A device fixing platform 508 is movably connected to the top of the hydraulic telescopic rod 507. The bottom end of the device fixing platform 508 is movably connected to the telescopic end of the electric telescopic rod 504.

[0024] In practical use, during liquefaction and cystic cavity treatment, the smooth interface allows the bone cement to anchor. The rotation of the drive motor 501 drives the rotating disk 502 to adjust the angle, thereby roughening the bone-bone cement interface and increasing the anchoring strength of the bone cement, facilitating treatment. The small hinge seat 503, in conjunction with the extension and retraction of the electric telescopic rod 504, allows the fixed platform 508 of the drive device to adjust its angle, thereby adjusting the electrodes and scraper for use.

[0025] The monitoring mechanism 3 includes a small electric telescopic rod 301 fixedly connected to one side of the device fixing platform 508. A pressure detector 302 is provided at one end of the small electric telescopic rod 301. An alarm 303 is fixedly connected to one side of the pressure detector 302. A medical imaging cable 304 is inserted and connected to the inner wall of the protective shell 1. A scraper is provided at one end of the small electric telescopic rod 301.

[0026] In practical use, the tool scrapes away the cyst wall, dead bone, and other devitalized tissues to roughen the bone-cement interface, thereby increasing the anchoring strength of the bone cement. Simultaneously, it must be considered that the vertebral body shaping puncture needle can be inserted through the channel. To facilitate pressure detection, a pressure detector 302 is installed for control and monitoring. The pressure detector 302 is extended or retracted by a small electric telescopic rod 301, which simultaneously pushes the scraper to remove the cyst wall and dead bone. An alarm 303 is installed to warn of excessive pressure. When taking X-ray images of the patient using a medical imaging line 304, the insertion distance can be determined.

[0027] Procedure Step 1: Preoperative Preparation Before performing vertebroplasty for Kumell's disease in the thoracic and lumbar spine, the surgeon needs to systematically assemble and functionally adjust the bone interface processing tools to ensure that they meet the surgical channel specifications of a diameter of <4mm, a length of 20cm, and have reliable mechanical and electrical properties. First, remove the sterile packaged protective shell 1, confirming that its exterior is intact and uncontaminated. Connect the support mechanism 2 to the bottom of the protective shell 1 via the fixed plate base 201, and tighten the connecting bolts to ensure mechanical stability. Then, unfold each of the first legs 204 and the second legs 206 in sequence. Adjust the length by adjusting the fixing screws 207 on the fixing sleeve 205, so that the support 208 can adapt to the plane of the operating table or fixation frame, achieving stable placement of the tool next to the surgical field and preventing shaking during the operation from affecting the accuracy of the operation. Next, install the monitoring mechanism 3 and the angle adjustment mechanism 5. Connect the device fixing platform 508 to the small electric telescopic rod 301, and confirm that the pressure detector 302 and the alarm 303 are correctly connected. Start the system self-test program through the controller 404 in the wireless control mechanism 4 to check whether the wireless signal receiving module 402 and the signal transmission module 403 are communicating normally with the external control terminal, such as a tablet computer or surgical robot system. The data storage module 405 and the data analysis module 406 load preset surgical parameters, such as pressure safety thresholds and scraping speed curves. Finally, channel adaptability verification was performed: the tool tip, including the scraper and pressure detector 302, was simulatedly inserted into a puncture needle channel with a diameter of 3.8 mm and a length of 20 cm to confirm good passage and no mechanical interference. The entire procedure was performed under sterile conditions to ensure the tool reached a "surgical ready" state.

[0028] Operation Step Two: Tool Insertion After establishing the percutaneous vertebroplasty puncture needle channel, the bone interface treatment tool is slowly inserted into the patient's vertebral body along the channel, gradually approaching the liquefied cystic cavity area within the Kumell disease vertebra. The operator holds the rear of the protective housing 1 and gently pushes the front scraper and pressure detector 302 assembly along the puncture needle channel. At the same time, the operator monitors the position of the tool tip in real time through the external X-ray imaging system connected to the medical imaging line 304. During the advancement, the tool should keep its axis aligned with the channel to avoid lateral force that could cause tissue damage. When the tool tip reaches the edge of the cyst cavity, the advancement is paused, the wireless control mechanism 4 is activated, and a command is sent through the external control terminal. The controller 404 drives the drive motor 501 in the angle adjustment mechanism 5 to run at low speed, driving the rotating disk 502 to perform initial angle calibration, so that the scraper on the device fixed platform 508 is initially aligned with the direction of the cyst wall. At this time, the electric telescopic rod 504 and the hydraulic telescopic rod 507 work together, and through the guidance of the small hinge seat 503 and the guide rod 505, the spatial position of the scraper is finely adjusted so that it forms an appropriate angle with the cyst wall, in preparation for scraping. During this process, the pressure detector 302 monitors the contact pressure between the front end and the tissue in real time and sends the data to the terminal screen for display via the signal transmission module 403. If the pressure rises abnormally, the alarm 303 will issue an audible and visual alarm to prompt the operator to adjust the advancing force or direction to avoid penetrating the capsule wall or damaging normal bone tissue. Operation Step 3: Capsule Wall Scraping and Interface Roughening Treatment After positioning is completed, the cyst wall and dead bone and other devitalized tissues are scraped to roughen the bone-bone cement interface and enhance the anchoring strength of the bone cement. The operator sets the scraping mode, such as continuous rotary scraping or intermittent scraping, via the control terminal. The controller 404 instructs the drive motor 501 to rotate the rotating disk 502 at the set speed. In turn, the extension and retraction of the electric telescopic rod 504 pushes the scraper on the device's fixed platform 508 to reciprocate or rotate along the capsule wall surface. The scraper angle can be adjusted in real time via a small hinge seat 503 to adapt to capsule wall morphologies with different curvatures. During the scraping process, the small electric telescopic rod 301 dynamically adjusts the scraper's advance and retreat based on pressure feedback, the pressure detector 302 continuously monitors the scraping resistance, and the data analysis module 406 analyzes the pressure data to identify the differences between the capsule wall and normal bone tissue, thus achieving intelligent scraping control. If the pressure exceeds the safety threshold, the alarm 303 immediately sounds an alarm, and the system automatically pauses scraping to prevent excessive scraping from damaging the vertebral structure. During the scraping process, the medical imaging line 304 continuously transmits X-ray images, allowing the surgeon to observe the scraping range and depth in real time, ensuring that only devitalized tissue is treated while preserving healthy bone structure. The debris generated during scraping can be flushed out through the puncture needle channel.

[0029] Step 4: Evaluation of scraping effect and maintenance of pressure After scraping is completed, the effect of bone interface treatment needs to be evaluated, and appropriate intracavitary pressure should be maintained to prepare for bone cement injection. The surgeon first uses X-ray imaging to confirm whether the scraping area covers the entire target area, whether the cyst cavity is fully open, and whether the interface has achieved uniform roughening. Subsequently, the control terminal instructs the pressure detector 302 to perform pressure mapping on the cyst cavity, record pressure distribution data at different locations, and generate a pressure cloud map through the data analysis module 406 to evaluate the cavity morphology and mechanical environment. If a localized area is found to be still relatively smooth or has residual bone, the scraping program can be restarted for targeted repair. At this time, the angle adjustment mechanism 5 can quickly adjust the scraper's posture to achieve high-precision finishing of specific areas. After the assessment is completed, the tool tip remains temporarily in the cyst cavity to maintain appropriate negative or neutral pressure, preventing collapse of surrounding tissues or bleeding that could obstruct the field of vision. Pressure detector 302 continuously monitors pressure changes; if abnormal fluctuations occur, such as bleeding causing increased pressure, the system automatically alerts the operator to take appropriate action.

[0030] Step 5: Tool Removal Once the bone interface treatment is satisfactory, the tools are safely removed, completing the surgical procedure. First, the control terminal instructs the small electric telescopic rod 301 to retract the scraper, and the pressure detector 302 stops detecting. The drive motor 501 resets, and the angle adjustment mechanism 5 returns to its initial position. Subsequently, the operator slowly withdraws the tool tip along the puncture needle channel, maintaining X-ray image monitoring during withdrawal to avoid scratching the tissue around the channel. After the tools are completely removed, a cleaning and disinfection procedure is immediately performed for future use. The data storage module 405 automatically saves data such as the pressure curve, scraping time, and image screenshots of this surgery, which can be used for postoperative analysis and medical record archiving.
