Description

Technical Field

[0001] This invention relates to the technical field of medical devices, specifically to a vertebral universal repositioning device for orthopedic spinal surgery. Background Technology

[0002] The spine is formed by the connection of vertebrae and coccyx via ligaments, joints, and intervertebral discs. The upper end of the spine supports the skull, the lower end connects to the hip bones, the middle part attaches to the ribs, and it serves as the posterior wall of the thoracic, abdominal, and pelvic cavities. The spine functions to support the trunk, protect internal organs, protect the spinal cord, and facilitate movement. During surgery on spinal patients, a vertebral universal repositioning device is used for clamping and positioning.

[0003] The vertebral universal repositioning device for orthopedic spinal surgery disclosed in Chinese Patent Publication No. CN114711937A employs a lateral adjustment component and a clamping component to achieve rapid adjustment of the vertebral body clamping and positioning. It also features a snap-fit ​​groove for easy replacement of the clamping frame, thus increasing the ease of operation of the vertebral universal repositioning device. However, it has the following problems:

[0004] I. The vertebral universal repositioning device used in orthopedic spinal surgery is fixed using only a simple fixing component. In actual surgery, the repositioning device needs to be moved, which increases the operation time and workload.

[0005] Second, using a clamp to hold the vertebral body of the spine cannot visually show the contact pressure on the patient's vertebral body, increasing the risk of spinal surgery. Summary of the Invention

[0006] To address the issues raised by the aforementioned universal vertebral repositioning devices used in orthopedic spinal surgeries, which rely on simple fixation components and increase operation time and workload when the device needs to be moved during actual surgery, and the lack of a clear view of the contact pressure on the vertebrae when using clamping frames, thus increasing the risks associated with spinal surgery, the aim is to achieve rapid separation and fixation of the universal repositioning device from the operating table, and to provide a clear and adjustable view of the clamping pressure on the vertebrae.

[0007] This invention is achieved through the following technical solution: a vertebral universal repositioning device for orthopedic spinal surgery, comprising a base cover, a sliding plate movably connected to the inner side of the base cover for controlling the fastening and separation of the base cover from the spinal surgery worktable, a pushing component movably connected to the outer side of the sliding plate for controlling the movement of the sliding plate, and a positioning plate fixedly connected to the outer side of the sliding plate for fixing the base cover to the surgical worktable. A locking plate for adjusting the horizontal position of the spinal vertebra is fixedly connected to the outer side of the base cover, a sliding component for adjusting the horizontal position of the spinal vertebra is movably connected to the inner side of the locking plate, a curved frame for adjusting the height position of the spinal vertebra is fixedly connected to the outer side of the sliding component, a height plate for adjusting the vertical height is slidably connected to the outer side of the curved frame, and a first screw for fixing the height plate and the curved frame is movably connected to the outer side of the height plate. The height plate is externally slidably connected to a transverse shift frame for fine-tuning the position of the spinal vertebrae. The transverse shift frame is externally movably connected to a second screw for fixing the transverse shift frame and the height plate. The transverse shift frame is internally slidably connected to a movable block for clamping the patient's spinal vertebrae. The movable block is externally fixedly connected to a cavity plate for positioning the patient's spinal vertebrae. The cavity plate is internally slidably connected to a pressure plate for contacting and clamping the patient's spinal vertebrae. The curved frame is externally movably connected to a pressure display component that works with the pressure plate to display and position the patient's spinal vertebrae.

[0008] Furthermore, the inner left and right ends of the bottom cover are movably connected to rollers for transporting the bottom cover, the outside of the positioning plate is fixedly connected to a one-way valve for venting internal air, and the pushing assembly includes a fixed shell fixedly connected to the outside of the bottom cover, a round rod slidably connected to the inside of the fixed shell to control the movement of the sliding plate, an iron plate fixedly connected to the top of the round rod, and a magnetic ring fixedly connected to the bottom of the fixed shell to control the sliding of the iron plate inside the fixed shell.

[0009] Furthermore, the two ends of the round rod are fixedly connected to the outside of the slide plate and the outside of the iron plate, respectively. The fixed shell, the round rod, the iron plate, and the magnetic ring form a closed space filled with nitrogen gas. The round rod penetrates the wall thickness surface of the bottom cover and is fixedly connected to the top of the slide plate.

[0010] Furthermore, the positioning plate and the bottom cover are positioned and matched in specifications. The sliding assembly includes a stud that is movably connected to the inner side of the card plate to adjust the horizontal position of the bending frame, a guide plate that is slidably engaged with the inner side of the card plate and rotatably connected to the stud, and an electric motor that is fixedly connected to the top of the card plate to provide power to the stud.

[0011] Furthermore, the motor and the stud are fixedly connected by a connecting shaft, the length of the stud matches the length specification of the clamping plate, and the guide plate is fixedly connected to the end of the bending frame.

[0012] Furthermore, the height plate and the bending frame are positioned and matched in specifications, the transverse frame and the height plate are positioned and matched in specifications, and a linear motor for driving the movable block to slide is fixedly connected to the outside of the transverse frame. The linear motor passes through the transverse frame and is fixedly connected to the outside of the movable block.

[0013] Furthermore, the pressure display assembly includes a transparent graduated cylinder fixedly connected to the top of the bending frame to display the force exerted by the pressure plate on the patient's vertebral body, a piston plate slidably connected to the inside of the transparent graduated cylinder to display the pressure of the pressure plate on the vertebral body in real time, and a spring rope fixedly connected to the outside of the piston plate to control the repositioning of the piston plate. The transparent graduated cylinder is connected to the cavity plate through a flexible tube, the pressure plate is slidably and sealed to the cavity plate, and nitrogen gas is added inside the cavity plate.

[0014] This invention provides a vertebral universal repositioning device for orthopedic spinal surgery. It has the following beneficial effects:

[0015] The iron plate is attracted by the magnetic force of the magnetic ring and slides to drive the round rod. The round rod slides and drives the sliding plate to slide. The sliding plate causes the positioning plate to adhere to the operating table surface, thus enabling the rapid fixation and separation of the bottom cover from the operating table surface. At the same time, the bending frame is adjusted horizontally by the guide plate, the height plate is adjusted vertically, and the transverse frame is finely adjusted horizontally. This allows the pressure plate to position and clamp the patient's vertebral body under the action of the movable block. The pressure plate and the cavity plate work together to push the piston plate. Under the elastic force of the elastic rope, the pressure plate dynamically displays the value of the contact clamping pressure of the pressure plate on the patient's vertebral body in real time in the transparent graduated cylinder.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] An example of the vertebral body universal repositioning device used in orthopedic spinal surgery is as follows:

[0034] Example 1:

[0035] Please see Figure 1 - Figure 2 , Figure 5 - Figure 8 A vertebral universal repositioning device for orthopedic spinal surgery includes a base cover 1. A sliding plate 11 is movably connected to the inner side of the base cover 1 for controlling the fastening and separation of the base cover 1 from the spinal surgery worktable. A pushing assembly 12 is movably connected to the outer side of the sliding plate 11 for controlling its movement. Rollers 14 for transporting the base cover 1 are movably connected to the left and right ends of the inner side of the base cover 1. A one-way valve 15 for venting internal air is fixedly connected to the outer side of a positioning disc 13. The pushing assembly 12 includes a fixed housing 121 fixedly connected to the outside of the base cover 1, a round rod 122 slidably connected to the inside of the fixed housing 121 for controlling the movement of the sliding plate 11, an iron plate 123 fixedly connected to the top of the round rod 122, and a magnetic ring 124 fixedly connected to the bottom inside the fixed housing 121 for controlling the sliding of the iron plate 123 inside the fixed housing 121.

[0036] The two ends of the round rod 122 are fixedly connected to the outside of the slide plate 11 and the outside of the iron plate 123, respectively. The fixed shell 121, the round rod 122, the iron plate 123, and the magnetic ring 124 form a closed space filled with nitrogen gas. The round rod 122 penetrates the wall thickness surface of the bottom cover 1 and is fixedly connected to the top of the slide plate 11.

[0037] During orthopedic spinal surgery, surgeons need to reposition and fix the vertebrae of the patient's spine. First, the surgeon places the base cover 1 on the surgical table surface, positioning the patient's body between the two base covers 1, corresponding to the position of the curved frame 22. The surgeon then energizes the magnetic coil 124 to generate an electromagnetic field. The iron plate 123, inside the fixation shell 121, slides under the influence of the Ampere force within the electromagnetic field of the magnetic coil 124. The sliding iron plate 123 compresses the nitrogen gas inside the fixation shell 121. The sliding rod 122 extends outside the fixation shell 121, causing the sliding plate 11 to slide inside the base cover 1. The sliding plate 11 then moves the positioning disc 13. The movement of the positioning plate 13 drives the one-way valve 15 to move. The positioning plate 13 moves until it contacts and deforms against the surgical worktable. The deformation of the positioning plate 13 causes the air inside to be squeezed out through the one-way valve 15, thereby creating a negative pressure inside the positioning plate 13 and securing it to the surgical worktable. This fixes the bottom cover 1 to the surgical worktable. Similarly, when it is necessary to separate the bottom cover 1 from the worktable, the user operates the magnetic ring 124 to stop the power supply. The iron plate 123 slides back to its original position under the action of compressed nitrogen inside the fixed shell 121. The sliding of the iron plate 123 drives the round rod 122 to reset. The reset of the round rod 122 drives the slide plate 11 to reset. The reset of the slide plate 11 drives the positioning plate 13 to move and separate from the surgical worktable.

[0038] The external fixed connection of the slide plate 11 is a positioning plate 13 for fixing the bottom cover 1 to the surgical worktable. The positioning plate 13 is positioned and matched with the bottom cover 1.

[0039] The iron plate 123 is attracted by the magnetic force of the magnetic ring 124, which causes the round rod 122 to slide. The sliding of the round rod 122 causes the sliding plate 11 to slide, which causes the positioning plate 13 to adhere to the surgical worktable surface, thereby enabling the rapid fixation and separation of the bottom cover 1 from the surgical worktable surface.

[0040] Example 2:

[0041] Please see Figure 1 - Figure 4 , Figure 9 - Figure 15 A vertebral universal repositioning device for orthopedic spinal surgery includes a base cover 1. A locking plate 2 for adjusting the horizontal position of the spinal vertebra is fixedly connected to the outside of the base cover 1. A sliding assembly 21 for adjusting the horizontal position of the spinal vertebra is movably connected to the inside of the locking plate 2. The sliding assembly 21 includes a stud 211 movably connected to the inside of the locking plate 2 to adjust the horizontal position of the bending frame 22, a guide plate 212 slidably locked to the inside of the locking plate 2 and rotatably connected to the stud 211, and an electric motor 213 fixedly connected to the top of the locking plate 2 to provide power to the stud 211.

[0042] The motor 213 is fixedly connected to the stud 211 via a connecting shaft. The length of the stud 211 matches the length of the clamping plate 2. The guide plate 212 is fixedly connected to the end of the bending frame 22.

[0043] The sliding assembly 21 is externally fixedly connected to a curved frame 22 for positioning and adjusting the height of the spinal vertebrae. The curved frame 22 is externally slidably connected to a height plate 23 for adjusting the vertical height. The height plate 23 is externally movably connected to a first screw 24 for fixing the height plate 23 and the curved frame 22.

[0044] The height plate 23 is externally slidably connected to a transverse frame 25 for fine-tuning the position of the spinal vertebrae. The transverse frame 25 is externally movably connected to a second screw 26 for fixing the transverse frame 25 and the height plate 23. The height plate 23 and the curved frame 22 are in the same position and have the same specifications. The transverse frame 25 and the height plate 23 are in the same position and have the same specifications. The transverse frame 25 is externally fixedly connected to a linear motor 34 for driving the movable block 3 to slide. The linear motor 34 passes through the transverse frame 25 and is externally fixedly connected to the movable block 3.

[0045] Based on Embodiment 1, after the base cover 1 is fixed to the operating table surface, the doctor operates the motor 213 to drive the stud 211 to rotate inside the clamping plate 2. The rotation of the stud 211 causes the guide plate 212 to slide horizontally inside the clamping plate 2. The horizontal sliding of the guide plate 212 causes the bending frame 22 to slide horizontally for position adjustment. After the bending frame 22 slides horizontally, the cavity plate 31 and the pressure plate 32 move horizontally to the position aligned with the vertebral body of the spinal patient, the doctor stops the operation of the motor 213. The doctor then manually operates the height plate 23 to slide outside the bending frame 22, causing the cavity plate 31 and the pressure plate 32 to adjust their vertical height position. After that, the doctor fixes the height plate 23 to the bending frame 22 by rotating the first screw 24. Subsequently, the doctor manually operates the transverse sliding frame 25 to slide horizontally outside the height plate 23. The horizontal sliding of the transverse sliding frame 25 causes the movable block 3 to move horizontally along the length of the height plate 23. The three-way horizontal movement drives the cavity plate 31 and pressure plate 32 to make horizontal fine adjustments along the length direction of the height plate 23 to align with the vertebral body of the spinal patient that needs to be clamped. The doctor operates the linear motor 34 to drive the movable block 3 to slide inside the transverse frame 25. The sliding of the movable block 3 drives the cavity plate 31 to move. The movement of the cavity plate 31 drives the movement of the pressure plate 32 to fix the vertebral body of the patient's spine. The pressure plate 32 contacts and clamps the vertebral body of the patient's spine, so that the pressure plate 32 slides inside the cavity plate 31 due to the reaction force of the vertebral body. The sliding of the pressure plate 32 compresses the nitrogen inside the cavity plate 31 and delivers it to the transparent scale cylinder 331 through the hose. The nitrogen pushes the piston plate 332 inside the transparent scale cylinder 331 to slide. The sliding of the piston plate 332 causes the elastic rope 333 to extend. The piston plate 332 slides with the clamping force of the pressure plate 32 on the vertebral body and cooperates with the transparent scale cylinder 331 to display the pressure of the pressure plate 32 on the vertebral body in real time.

[0046] The inner side of the transverse frame 25 is slidably connected to a movable block 3 for clamping the patient's vertebral body. The outer side of the movable block 3 is fixedly connected to a cavity plate 31 for positioning the patient's vertebral body. The inner side of the cavity plate 31 is slidably connected to a pressure plate 32 for contacting and clamping the patient's vertebral body. The outer side of the curved frame 22 is movably connected to a pressure display component 33 that cooperates with the pressure plate 32 to display and position the patient's vertebral body.

[0047] The pressure display assembly 33 includes a transparent graduated cylinder 331 fixedly connected to the top of the bending frame 22 to display the force exerted by the pressure plate 32 on the patient's vertebral body; a piston plate 332 slidably connected to the inside of the transparent graduated cylinder 331 to display the pressure of the pressure plate 32 on the vertebral body in real time; and a spring rope 333 fixedly connected to the outside of the piston plate 332 to control the repositioning of the piston plate 332. The transparent graduated cylinder 331 is connected to the cavity plate 31 through a hose, and the pressure plate 32 is slidably and sealed to the cavity plate 31. Nitrogen gas is added inside the cavity plate 31.

[0048] The bending frame 22 is adjusted horizontally by the guide plate 212, the height plate 23 is adjusted vertically, and the transverse frame 25 is finely adjusted horizontally so that the pressure plate 32, driven by the movable block 3, positions and clamps the patient's vertebral body. The pressure plate 32 and the cavity plate 31 work together to push the piston plate 332 under the elastic force of the elastic rope 333, which dynamically displays the value of the contact clamping pressure of the pressure plate 32 on the patient's vertebral body in real time within the transparent scale cylinder 331.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
