Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a nursing support after pediatric surgery for fracture reduction of limbs. Background Art

[0002] Fracture reduction surgery is a common treatment method in orthopedics, which aims to restore the fracture ends to their normal anatomical position through manipulation or surgery, and maintain their stability through internal or external fixation devices. However, postoperative incision care is crucial for the patient's recovery. The traditional method is to fix and support the fracture site with plaster, which is heavy and takes a long time to fix, leading to limb muscle atrophy and joint stiffness. It is also airtight and prone to sweating, which may cause problems such as surgical incision infection.

[0003] In recent years, with the development of rehabilitation medicine, non-complete encapsulation braces have gradually attracted attention, such as YD-027 (elbow brace) and SK-F05 (knee brace). This type of brace combines the dual functions of fixation and partial movement, which can provide stable support and allow a certain degree of limb movement, which helps to promote fracture healing and functional recovery. At the same time, non-complete encapsulation braces usually adopt an open design, covering only part of the limb to avoid complete encirclement, which can avoid surgical incisions and reduce pressure on the wound.

[0004] However, in actual use, due to children's active nature, the straps may easily become loose due to children's activities or external collisions, causing the surgical incision and surrounding skin to be pulled, increasing the tension of the surgical incision, and causing the surgical incision to rupture and cause secondary injury. Therefore, it is difficult to automatically adjust the tension of the skin on both sides of the surgical incision.

[0005] For this reason, we proposed a postoperative nursing support for pediatric limb fracture reduction. Summary of the invention

[0010] Preferably, the face-lifting mechanism includes a turntable connected to the bottom of the inner wall of the protective shell for fixed-axis rotation, and arc grooves are provided at symmetrical positions on both sides of the turntable near the support rods, and movable blocks are fixedly connected to one end of the support rods on both sides near the turntable, and the movable blocks on both sides respectively penetrate the inner walls of the arc grooves on the adjacent sides and are movably connected, and a circular plate is coaxially fixedly connected to the top of the turntable, and a through hole is provided on the circular plate for the piston plate to drive the turntable to rotate on a fixed axis.

[0011] Preferably, a cylindrical block is fixedly connected to the bottom of the piston plate at a position corresponding to the through hole, and the outer contour of the cylindrical block is adapted to the aperture of the through hole, an L-shaped groove is provided on the inner wall of the cylindrical shell for driving the piston plate to rotate, a slider is fixedly connected to the side of the outer contour of the piston plate close to the L-shaped groove, and the slider penetrates through the inner wall of the L-shaped groove and is movably connected.

[0012] Preferably, support grooves are provided on the protective shell at symmetrical positions on both sides of the track plate, the inner walls of the support grooves on both sides are connected with moving blocks for lifting and movement, the opposite ends of the moving blocks on both sides are fixedly connected with cylindrical sleeves, and the opposite sides of the cylindrical sleeves on both sides are rotatably connected with adjusting rods, the ends of the adjusting rods on both sides away from the cylindrical sleeves are respectively rotatably connected to the adjacent support rods through pins, and the cylindrical sleeves are provided with a buffer mechanism to reduce the impact force of external impact.

[0013] Preferably, the buffer mechanism includes two cylindrical sleeves connected to a cylindrical rod for lifting and lowering movement, the ends of the cylindrical rods on both sides are fixedly connected to buffer plates for reducing the impact force of external impact, and the opposite surfaces of the cylindrical sleeves and the buffer plates on both sides are fixedly connected to springs for guiding the buffer plates to reset.

[0014] Preferably, the movable block is provided with a tightening mechanism for tightening the strap, and the tightening mechanism includes U-shaped frames fixedly connected to the opposite ends of the movable blocks on both sides, and gears are fixedly connected to the symmetrical positions at both ends of the U-shaped frame on each side for driving the roller to rotate to tighten the strap, and gears are coaxially fixedly connected to the gears at the symmetrical positions at both ends of each roller, and the teeth on the gear and the gear are adapted to each other.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Through the synergistic effect of the cylindrical shell, piston plate and ventilation tube, the air in the suction cup can be quickly extracted to form a stable negative pressure adsorption, which not only ensures that the suction cup fits tightly on the skin on both sides of the surgical incision, but also effectively prevents the device from loosening or shifting due to children's activities or external interference. Compared with the traditional fixation method, the adsorption mechanism significantly improves the stability and reliability of the device at the incision, provides more reliable protection for the postoperative incision, and effectively avoids secondary injuries caused by device displacement.

[0017] 2. Through the linkage of the turntable, movable block and arc groove, the suction cups can move towards each other, so that the skin on both sides of the surgical incision can be actively tightened, which can effectively reduce the incision tension and reduce the risk of incision rupture due to skin pulling. Especially in the case of frequent activities of children, it can significantly reduce the probability of secondary injury after surgery. In addition, by adjusting the position of the piston plate, the degree of skin tightening can be flexibly adjusted according to the specific situation of the incision, further improving the applicability and safety of the device.

[0018] 3. Through the combination of the cylindrical sleeve, the buffer plate and the spring, a dynamic buffer function is provided for the device. When the protective device is subjected to external impact, the buffer plate can be quickly compressed under the action of the spring and absorb most of the impact energy, thereby effectively protecting the incision and bones from direct collision damage. It can not only resist sudden external impacts, but also reduce the risk of secondary injury to the incision caused by accidental collisions during children's daily activities. At the same time, the automatic reset function of the spring ensures that the buffer plate can quickly restore the protective state and continue to provide protection for the incision.

[0019] Fourth, the automatic tightening function of the strap is realized through the cooperation of the torsion spring, the roller and the toothed bar. When using it, the medical staff only need to pull the strap to the appropriate length, and the device can automatically complete the tightening operation to ensure that the protective shell is firmly fixed to the incision site. The automatic tightening mechanism not only simplifies the operation process and reduces the workload of medical staff, but also ensures that the strap will not loosen after tightening through the locking function of the toothed bar and the gear, further improving the stability and reliability of the device.

[0020] The coordinated use of the above-mentioned structure solves the problem that, during actual use, the existing device is difficult to automatically adjust the skin tension on both sides of the surgical incision because children are naturally active and the device may become loose due to children's activities or external collisions, resulting in pulling of the surgical incision and surrounding skin, increasing the tension of the surgical incision, and causing rupture of the surgical incision and secondary injury.

[0035] Embodiment 2:

[0036] On the basis of the first embodiment, further:

[0037] The adsorption mechanism includes a cylindrical shell 9 fixedly connected to the top center position of the inner wall of the protective shell 1, and ventilation pipes 10 are penetrated and fixedly connected at the symmetrical positions on both sides of the cylindrical shell 9 near the end. The ends of the ventilation pipes 10 on both sides away from the cylindrical shell 9 are respectively penetrated to the inner wall of the adjacent suction cup 8 and fixedly connected, and the protective shell 1 is penetrated by the ventilation pipes 10 and movably connected.

[0038] The inner wall of the cylindrical shell 9 is movably connected with a piston plate 11 for extracting or discharging air in the suction cup 8, and the piston plate 11 is penetrated and rotatably connected with a lifting rod 12 driven by a power mechanism, and the ends of the cylindrical shell 9 and the protective shell 1 are penetrated by the lifting rod 12 and connected for lifting and movement.

[0040] like Figure 2 , Figure 3 and Figure 8 As shown, when the lifting rod 12 pushes the piston plate 11 to move toward the bottom of the cylindrical shell 9, and the internal air pressure of the cylindrical shell 9 near one end of the ventilation tube 10 is in a negative pressure state, the ventilation tube 10 can draw the air inside the suction cup 8 to the inner wall of the cylindrical shell 9, and the suction cup 8 fits against the skin. At this time, the inside of the suction cup 8 is in a negative pressure state, so that the suction cup 8 can be adsorbed on the patient's skin, further improving the stability of the protective shell 1 in protecting the surgical incision.

[0041] When the lifting rod 12 pulls the piston plate 11 to reset toward the top of the cylindrical shell 9, the internal air pressure of the cylindrical shell 9 near the end of the ventilation tube 10 is positive, and the ventilation tube 10 discharges the air inside the cylindrical shell 9 into the suction cup 8, so that the suction cup 8 can be detached from the skin, making it easier for medical staff to remove the protective device after use.

At this time, the column block 16 moves and penetrates to the inner wall of the through hole 171, and the column block 16 can rotate synchronously with the piston plate 11. The circular plate 17 can move, and then the turntable 13 can rotate in the direction of C on a fixed axis under the action of the columnar block 16. The movable block 14 can pull the support rods 7 on both sides to move horizontally toward each other under the action of the arc groove 131, and the suction cup 8 is adsorbed on the skin, so that the suction cup 8 can pull the skin on both sides of the surgical incision to tighten under the action of the support rod 7, thereby reducing the tension of the skin on both sides of the surgical incision, avoiding the problem of secondary injury caused by the rupture of the surgical incision due to the pulling of the skin on both sides of the surgical incision due to external expansion, and further improving the safety of surgical incision protection.
