Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an external fixation bracket auxiliary device for fracture patients. Background Art

[0002] External fixators are important medical devices used to treat fractures, particularly open, complex, or multi-segment fractures. These devices stabilize the fracture site through external fixation, allowing the bone to heal in a relatively stable state. External fixators can be adjusted to the patient's specific needs to accommodate bones of varying sizes and shapes, providing improved fixation.

[0003] In existing technologies, bone fixation screws in fracture patients are typically disinfected at the screw entry point using cotton balls or gauze soaked in iodine. However, these methods have limitations. For example, if the cotton balls or gauze are not securely fixed, they can easily fall off, resulting in inefficient care.

[0004] In summary, how to solve the problem in the existing technology of using cotton balls or gauze soaked in iodine to disinfect the entry point of bone screws, which easily causes them to fall off and dry out, thereby leading to low nursing efficiency, has become a difficult problem that needs to be solved urgently in this field. Therefore, it is necessary to propose an external fixation bracket auxiliary device for fracture patients. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides an external fixation bracket auxiliary device for fracture patients, which drives the rotating plate to rotate through the driving component, thereby driving the clamping or releasing action of the splint, reducing the movement or falling off of the storage box during the disinfection process, and improving the work efficiency of bone screw care.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: an external fixation bracket auxiliary device for fracture patients, comprising a bracket body and a storage box, the storage box being used to store a carrier with disinfectant; an opening is opened on the storage box, and a fixing component for fixing the storage box is provided on the bracket body.

[0007] The fixing assembly includes a fixed plate, a rotating plate and several clamping plates. The fixed plate is fixedly connected to the bracket body; the fixed plate has a card slot along its circumference, the clamping plates are all located in the card slot and slide with the card slot, and the bottom of the clamping plates are hinged with a hinge rod; the rotating plate rotates to fit with the bottom of the fixed plate, and the end of the hinge rod away from the clamping plate is hinged to the rotating plate; the fixed plate and the rotating plate both have interfaces connected to the opening.

[0008] The fixed plate is provided with a driving assembly for driving the rotating plate to rotate.

[0009] An opening and closing component for opening and closing the interface is provided on the rotating plate.

[0010] A shielding component is provided at the bottom of the fixed plate to prevent the disinfectant from being dried out by the air; the driving component is used to drive the opening and closing component and the shielding component to operate synchronously.

[0011] The technical principles of the above solution are as follows: The driving assembly drives the rotating plate to rotate. Since the hinged rods are hinged to the clamping plate and the rotating plate, and the clamping plate and the slot are slidably matched, the rotation of the rotating plate can drive the clamping plate to clamp or release. By placing the storage box on the fixed plate, it can be clamped and fixed by the circumferential clamping plates. The design of the opening and closing assembly can connect the interface with the opening of the storage box, so that the carrier with disinfectant can be applied to the position to be disinfected. The design of the shielding assembly can shield the disinfection position, thereby reducing the occurrence of the disinfectant drying out.

[0012] The above scheme has the following beneficial effects: 1. The present invention utilizes a drive assembly to rotate the rotating plate, which in turn drives the clamping or releasing action of the splint via a hinged rod. This design makes the clamping and releasing process flexible and easy to operate; simply controlling the drive assembly allows for rapid securing or releasing of the storage box, improving the efficiency of bone screw care. Compared to traditional devices that rely on manual fixation, the sliding fit between the splint and the slot, as well as the circumferential arrangement of the splints, ensures the stable fixation of the storage box on the fixed plate. This not only reduces the risk of the storage box moving or falling off during the disinfection process, but also improves the reliability of the entire disinfection process.

[0013] 2. Compared to direct spraying or immersion methods, this invention utilizes an opening and closing assembly design that allows the interface to communicate with the opening of the storage box, allowing the disinfectant carrier to effectively apply to the location to be disinfected. This design not only expands the functionality of the device but also makes the disinfection process more precise and efficient.

[0014] 3. Compared with the traditional method in which the disinfectant easily loses its disinfection effect due to air drying, the design of the shielding component of the present invention helps to reduce the occurrence of disinfectant drying, which not only saves the amount of disinfectant used; at the same time, it can also maintain the humidity of the disinfection environment to a certain extent, thereby improving the disinfection effect.

[0015] Furthermore, the driving assembly includes a controller, a gear, an outer ring gear and a rotating member, the controller is used to control the rotation of the rotating member; the rotating member is embedded and installed in the fixed plate, and the output shaft of the rotating member is coaxially fixedly connected to the gear; the gear and the outer ring gear are engaged with each other, and the outer ring gear is fixedly connected to the outer wall of the rotating plate.

[0016] Beneficial effect: The rotating part is used to drive the gear to rotate. Since the gear is engaged with the outer ring gear, and the outer ring gear is fixedly connected to the outer wall of the rotating plate, the rotation of the gear can drive the outer ring gear to rotate, and the rotation of the outer ring gear drives the rotating plate to rotate, thereby achieving efficient power transmission effect.

[0017] Furthermore, the opening and closing assembly includes an interface plate and a plurality of sliding blocks, the interface plate having a through hole connected to the interface; the top of each sliding block is fixedly connected to a sliding rod, and the rotating plate has a sliding groove along its circumference for the sliding rod to slide; the sliding grooves are all arc-shaped, and the interface plate is located below the rotating plate; the bottom of each sliding block is fixedly connected to a clamping rod, and the interface plate has an inclined groove along its circumference for the clamping rod to slide; The fixed plate is provided with a limiting component for providing a limit for the rotating plate.

[0018] Beneficial Effects: Because the sliding block is fixedly connected to a slide rod and a clamping rod, the rotating plate has a slide groove for the slide rod to slide, and the interface plate has an inclined groove for the clamping rod to slide, the slide rod can drive the sliding block to rotate synchronously when the rotating plate rotates, causing the sliding blocks to move toward or away from the central opening, thereby opening or closing the opening on the interface plate. When the opening is opened, the carrier in the storage box can fall into the opening, thereby disinfecting the entry point of the bone screw. By designing the slide groove into an arc, the slide rod can move stably within the slide groove, and the slide block can form a circular motion trajectory around the opening, so that the movement of the slide block can better fit the shape of the opening.

[0019] Furthermore, the limiting assembly includes a plurality of vertical plates fixedly connected to the top of the interface plate in a circumferential direction; the tops of the vertical plates all pass through the rotating plate and are fixedly connected to the fixed plate; and an arc groove is opened on the rotating plate for the vertical plates to move.

[0020] Beneficial effect: The design of the vertical plate can prevent the rotating plate from shifting during rotation, and the interface plate can block the rotating plate to avoid the risk of the rotating plate falling.

[0021] Furthermore, the shielding assembly includes several telescopic rods and several clamping arms, the telescopic rods are fixedly connected to the bottom of the clamping plate located on the same straight line; the clamping arms are fixedly connected to the telescopic rods adjacent to them, and a shielding layer is fixedly connected to the clamping arms, and the side of the shielding layer away from the clamping arm is fixedly connected to the bracket body.

[0022] Beneficial Effects: Because the telescopic rods are fixedly connected to the bottom of the clamping plate, and the clamping arms are fixedly connected to the adjacent telescopic rods, the clamping plate can drive the telescopic rods to extend and retract when the clamping plate is clamped, and the movement of the telescopic rods drives the clamping arms toward or away from each other. Because the clamping arms are fixedly connected to a shielding layer, and the other side of the shielding layer is fixedly connected to the bracket body, the movement of the clamping arms can drive the shielding layer to block the area, reducing direct contact between the outside air and the disinfectant, thereby reducing the evaporation rate of the disinfectant.

[0023] Furthermore, the cross-sections of the plywood are all in the shape of an "I".

[0024] Beneficial effect: By designing the cross section of the splint into an "I" shape, its vertical end can directly contact the slot, so that the slot can stably clamp the splint, thereby allowing the splint to remain stable during movement.

[0025] Furthermore, the hinged rods are all in the shape of a Chinese character "へ".

[0026] Beneficial effect: By designing the hinge rod into a "へ" shape, the rotation amplitude of the rotating plate can be reduced, so that the clamping plate can have a stronger clamping force by utilizing a smaller rotation plate amplitude, further improving the clamping stability of the clamping plate.

[0027] Furthermore, a humidity sensor is fixedly connected to the bottom of the interface board, and the controller is used to receive and store humidity information sent by the humidity sensor.

[0028] Beneficial effects: The humidity sensor can monitor the humidity information of the bone screw care position in real time. By setting the humidity threshold, a reminder can be issued when the disinfectant dries up, making it convenient for the operator to replace the carrier.

[0029] Furthermore, a buffer layer is fixedly connected to the top of each splint.

[0030] Beneficial effect: Through the design of the buffer layer, the splint can provide a buffer for the storage box when clamping the storage box, which can not only fix the storage box but also provide a buffering protection for it.

[0031] Furthermore, the number of the telescopic rods is at least two.

[0032] Beneficial effect: Through the design of multiple telescopic rods, the shielding layer can be used to shield the parts that need protection in multiple directions, further improving the protective effect of the shielding layer and reducing the occurrence of air drying.

[0033] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The following is further described in detail through specific implementation methods: Example 1:

[0042] As attached Figures 1-6 As shown: an external fixation bracket auxiliary device for fracture patients, including a bracket body 1 and a storage box 2, the storage box 2 is used to store a carrier with disinfectant, and in this embodiment, the carrier is a cotton ball; an opening is opened on the storage box 2, and a fixing component for fixing the storage box 2 is provided on the bracket body 1.

[0043] The fixing assembly includes a fixed plate 3, a rotating plate 4 and several clamping plates 5. The fixed plate 3 is fixedly connected to the bracket body 1 with screws; the fixed plate 3 has a card slot along its circumference, the clamping plates 5 are all located in the card slot and slide with the card slot, and the bottom of the clamping plates 5 are hinged with a hinge rod 6; the rotating plate 4 rotates to fit the bottom of the fixed plate 3, and the other end of the hinge rod 6 is hinged to the rotating plate 4; the fixed plate 3 and the rotating plate 4 are both provided with an interface connected to the opening.

[0044] Combine Figure 3 As shown, the fixed plate 3 is provided with a drive assembly for driving the rotating plate 4. The drive assembly includes a controller, a gear 7, an outer ring gear 8, and a rotating member. In this embodiment, the rotating member is a motor 9. The controller is used to control the rotation of the motor 9. The motor 9 is embedded in the fixed plate 3, and the output shaft of the motor 9 is coaxially fixedly engaged with the gear 7. The gear 7 and the outer ring gear 8 are mutually meshed, and the outer ring gear 8 is fixedly connected to the outer wall of the rotating plate 4 by screws.

[0045] Combine Figure 5As shown, the rotating plate 4 is provided with an opening and closing assembly for opening and closing the interface. The opening and closing assembly includes an interface plate 11 and a number of sliding blocks 12. The interface plate 11 has a through opening connected to the interface; the top of the sliding block 12 is fixedly connected with a slide rod 13 by screws, and the rotating plate 4 has a sliding groove along its circumference for the slide rod 13 to slide; the sliding grooves are all arc-shaped. By designing the sliding grooves into an arc shape, the slide rod 13 can move stably in the sliding grooves, and the sliding block 12 can form a circular motion trajectory around the through opening, so that the movement of the sliding block 12 can better fit the shape of the through opening, making it tighter when closed. The interface plate 11 is located below the rotating plate 4; the bottom of the sliding block 12 is fixedly connected with a clamping rod 14 by screws, and the interface plate 11 has an inclined groove along its circumference for the clamping rod 14 to slide; The fixed plate 3 is equipped with a stopper assembly for the rotating plate 4. This assembly consists of a vertical plate 15 fixed to the top of the interface plate 11 by several circumferential screws. The tops of the vertical plates 15 extend through the rotating plate 4 and are screwed together with the fixed plate 3. The rotating plate 4 is provided with an arcuate slot for the vertical plates 15 to move. The design of the vertical plates 15 prevents the rotating plate 4 from shifting during rotation, and the interface plate 11 blocks the rotating plate 4, preventing it from falling.

[0046] A shielding assembly is installed at the bottom of the fixed plate 3 to prevent the disinfectant from drying out. A drive assembly is used to drive the opening and closing assembly and the shielding assembly to operate synchronously. The shielding assembly includes several telescopic rods 16 and several clamping arms 17. The telescopic rods 16 are screwed to the bottom of the clamping plate 5, which are located on the same straight line. The clamping arms 17 are screwed to the adjacent telescopic rods 16. A shielding layer 18 is fixedly bonded to each clamping arm 17. In this embodiment, the shielding layer 18 is made of a flexible material. The other side of the shielding layer 18 is fixedly bonded to the bracket body 1.

[0047] The specific implementation process is as follows: First, before performing bone screw care, fixation plate 3 is installed on support body 1, with the interface of fixation plate 3 aligned with the bone screw entry point to be cared for. Motor 9 drives gear 7 to rotate. Since gear 7 meshes with outer ring gear 8, which is screw-fixed to the outer wall of rotating plate 4, the rotation of gear 7 drives outer ring gear 8, which in turn drives rotating plate 4, achieving efficient power transmission.

[0048] Since the hinge rod 6 is hinged to the clamping plate 5 and the rotating plate 4, the clamping plate 5 slides in conjunction with the slot, so the clamping plate 5 can be clamped or released by the rotation of the rotating plate 4. Figure 3For example, when the outer gear ring 8 drives the rotating plate 4 to rotate counterclockwise, the hinged rod 6 on the rotating plate 4 drives the clamping plate 5 to clamp the middle; otherwise, the clamping plate 5 can be pushed to the sides to release it. By placing the storage box 2 on the fixed plate 3, the circumferential clamping plates 5 can clamp and fix it, preventing it from falling.

[0049] Since the sliding block 12 is screwed and fixed with the sliding rod 13 and the clamping rod 14, the rotating plate 4 is provided with a sliding groove for the sliding rod 13 to slide, and the interface plate 11 is provided with an inclined groove for the clamping rod 14 to slide, when the rotating plate 4 rotates, the sliding block 12 can be driven to rotate synchronously by the sliding rod 13, thereby making the sliding blocks 12 move closer to or away from each other toward the central opening. Figure 5 For example, when the rotating plate 4 rotates clockwise, the slide rod 13 moves toward the middle opening along the slide groove, thereby causing the sliding block 12 below to move toward the opening through the slide rod 13; conversely, the sliding block 12 can be moved away from the opening, and the opening on the interface plate 11 can be opened or closed in this way. When opened, the cotton balls in the storage box 2 can fall into the opening, thereby using the cotton balls to disinfect the entry point of the bone screw.

[0050] Because the telescopic rods 16 are all screw-fixed to the bottom of the clamping plate 5, and the clamping arms 17 are all screw-fixed to the adjacent telescopic rods 16, when the clamping plate 5 is clamped, the telescopic rods 16 can be driven to extend and retract, and the movement of the telescopic rods 16 drives the clamping arms 17 toward or away from each other. Because a shielding layer 18 is fixedly bonded to the clamping arms 17, and the other side of the shielding layer 18 is fixedly bonded to the bracket body 1, the movement of the clamping arms 17 can drive the shielding layer 18 made of flexible material to block the area, reducing direct contact between the outside air and the disinfectant, thereby reducing the volatilization rate of the disinfectant.

[0051] In the prior art, when caring for bone screws, cotton balls or gauze soaked in disinfectant are usually used to disinfect the entrance of the bone screws, which may result in insufficient fixation or the disinfectant easily drying up. In this embodiment, the rotating plate 4 is driven to rotate by the gear 7 and the outer ring gear 8, and the clamping or releasing action of the splint 5 is then driven by the hinge rod 6. This design makes the clamping and releasing process flexible and easy to operate; the storage box 2 can be quickly fixed or released by simply controlling the opening and closing of the motor 9, thereby improving the efficiency of bone screw care. The sliding fit between the splint 5 and the card slot and the circumferential arrangement of the splint 5 ensure that the storage box 2 is stably fixed on the fixed plate 3. This not only reduces the movement or falling off of the storage box 2 during the disinfection process, but also improves the reliability of the entire disinfection process.

[0052] By utilizing the design of a plurality of sliding blocks 12, the interface can be connected to the opening of the storage box 2 while the rotating plate 4 drives the clamping plate 5 to clamp the storage box 2, thereby allowing the disinfectant carrier to effectively act on the position to be disinfected. This design not only expands the functionality of the device, but also makes the disinfection process more accurate and efficient. By utilizing the design of the clamping arm 17 and the shielding layer 18, the shielding layer 18 can be opened when the clamping plate 5 is clamped to block the position to be blocked, which helps to reduce the occurrence of the disinfectant drying out. This not only saves the amount of disinfectant used; at the same time, it can also maintain the humidity of the disinfection environment to a certain extent, improving the disinfection effect.

[0053] Example 2:

[0054] As attached Figure 2 As shown, the difference from the above embodiment is that the cross section of the clamping plate 5 is in the shape of an "I".

[0055] The specific implementation process is as follows: by designing the cross section of the splint 5 into an "I" shape, its vertical end can directly contact the slot, so that the slot can stably clamp the splint 5, and thus the splint 5 can remain stable during movement.

[0056] Example 3:

[0057] As attached Figure 3 As shown, the difference from the above embodiment is that the hinge rods 6 are all in the shape of a Chinese character "へ".

[0058] The specific implementation process is as follows: by designing the hinge rod 6 into a "へ" shape, the rotation amplitude of the rotating plate 4 can be reduced, so that the smaller rotation amplitude of the rotating plate 4 can be utilized to make the clamping plate 5 have a stronger clamping force, further improving the clamping stability of the clamping plate 5.

[0059] Example 4:

[0060] As attached Figure 5 As shown, the difference from the above embodiment is that a humidity sensor is further fixedly connected to the bottom of the interface board 11 by screws, and the controller is used to receive and store humidity information sent by the humidity sensor.

[0061] The specific implementation process is as follows: The humidity information of the bone screw care position can be monitored in real time through the humidity sensor. By setting the humidity threshold, a reminder can be issued when the disinfectant dries up, making it convenient for the operator to replace the cotton ball.

[0062] Example 5:

[0063] As attached Figure 1 As shown, the difference from the above embodiment is that a buffer layer 10 is fixedly bonded to the top of each splint 5 .

[0064] The specific implementation process is as follows: through the design of the buffer layer 10, the splint 5 can provide a buffer for the storage box 2 when clamping the storage box 2, which can not only fix the storage box 2, but also provide a buffering protection effect for it.

[0065] Example 6;

[0066] As attached Figure 1 As shown, the difference from the above embodiment is that the number of telescopic rods 16 is at least two.

[0067] The specific implementation process is as follows: by designing the number of multiple telescopic rods 16, the shielding layer 18 can be used to shield the parts to be protected in multiple directions, further improving the protective effect of the shielding layer 18, thereby reducing the occurrence of air drying.

[0068] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
