Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an orthopedic external fixation splint. Background Art

[0002] An orthopedic external fixation splint is a medical device used for external fixation of fractures or joint injuries. It consists of components such as a fixation plate, a fixation screw, and a pad. This splint is widely used in orthopedic treatment. Its origin can be traced back to the early 20th century. With the development of medical technology, its scope of application has gradually expanded, and it has now become one of the important means of orthopedic treatment.

[0003] An orthopedic splint mentioned in an existing Chinese public patent (authorization announcement number: CN220256600U) includes a first splint, the inner wall of the first splint is provided with a first elastic band, and one end of the first elastic band is fixedly connected to a second splint. The utility model has the following advantages and effects: since the pressure after fixation often changes with the growth or disappearance of local swelling of the fracture, the splint fixation often fails and the fracture is dislocated again. Therefore, by passing the first elastic band through the bottom of the first splint and through the connecting sleeve, when it is necessary to adjust the clamping tightness of the first splint and the second splint, the end of the first elastic band on the inner wall of the fixing clamp can be adjusted by adjusting the length of the first elastic band extending, so that the clamping tightness between the first splint and the second splint can be adjusted. At this time, the extension length of the screw can be adjusted according to the gap, so that the splint assembly can adjust the pressure between the splints anytime and anywhere when in use.

[0004] In the above patent, the pressure between the splints can be adjusted at will during use through devices such as bolts and splints. However, in actual use, the multiple bolts installed on the splints may increase the difficulty of care and cleaning, especially when changing dressings or performing daily care. It is necessary to turn the bolts multiple times for installation or removal, making the device extremely inconvenient during use. For this reason, the present application provides an orthopedic external fixation splint. Utility Model Content

The present application provides an orthopedic external fixation splint.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] An orthopedic external fixation splint, comprising a first splint and a second splint. An air-permeable plate is installed inside both the first splint and the second splint. One side of the air-permeable plate is fixedly connected with skin-friendly cotton. Connecting blocks are fixedly connected to both ends of the second splint. Connecting grooves are opened at both ends of the first splint. Clamping components are symmetrically installed on both sides of the connecting block. Inflating components are installed inside both the first splint and the second splint.

[0008] By adopting the above technical solution, through the cooperation of the clamping component and the connecting groove, the first splint and the second splint can be quickly installed and fixed without using components such as bolts. After the first splint and the second splint are fixed, the inflating component can be started to operate. Through the operation of the inflating component, the two air-permeable plates can be squeezed to drive the skin-friendly cotton to closely fit the patient's limb, so that the device can adapt to patients of different body types. In addition, when dressing change is needed, only the second splint needs to be lifted upward, and the first splint and the second splint can be quickly separated to perform dressing change quickly.

[0009] Furthermore, a plurality of first springs are fixedly connected to the inner walls of both the first splint and the second splint. One ends of the plurality of first springs are fixedly connected to one side of the air-permeable plate.

[0010] By adopting the above technical solution, the air-permeable plate can be continuously resisted by the plurality of first springs, so that the device can adapt to patients of different body types. Even after the swelling of the fracture site subsides, the air-permeable plate and the skin-friendly cotton can still be attached to the limb.

[0011] Furthermore, ventilation grooves are opened between both the first splint and the second splint and the air-permeable plate. A plurality of air-permeable holes are evenly opened on the air-permeable plate.

One end of spring two is fixedly connected with a clamping block, and the clamping block is slidably connected inside the limiting groove.

[0014] By adopting the above technical solution, through the mutual cooperation of the clamping block and the connecting groove, the connecting block can be clamped inside the connecting groove, so that the first splint and the second splint can be quickly installed and fixed without using components such as bolts.

[0015] Furthermore, one end of the clamping block is arc-shaped, and clamping grooves with the same size as the arc-shaped end of the clamping block are symmetrically opened on both sides inside the connecting groove.

[0016] By adopting the above technical solution, the connection between the clamping plate one and the clamping plate two can be quickly released according to the arc end of the clamping block, thereby releasing the connection and fixation between the clamping plate one and the clamping plate two, greatly improving the removal speed between the clamping plate one and the clamping plate two.

[0017] Further, the inflation assembly includes air bags fixedly connected to the inner walls of the clamping plate one and the clamping plate two. One end of the air bag is fixedly connected with an air inlet pipe, and the other end of the air bag is fixedly connected with an air outlet valve.

[0019] Further, one end of the air inlet pipe is fixedly connected with a rubber sphere, and a valve is fixedly connected to the air inlet pipe.

[0020] By adopting the above technical solution, first open the valve and close the air outlet valve, and then squeeze the rubber sphere multiple times. By squeezing the rubber sphere, air can be squeezed into the interior of the air bag through the air inlet pipe, causing the air bag to gradually expand.

[0021] Further, two hook surfaces of the magic tape are symmetrically and fixedly connected to the outer wall of the clamping plate one, and two loop surfaces of the magic tape are symmetrically and fixedly connected to the outer wall of the clamping plate two.

[0022] By adopting the above technical solution, the hook surface of the magic tape is wound and adhered to the loop surface of the magic tape to perform secondary stabilization on the clamping plate one and the clamping plate two.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. In the present application, a connection block, a connection groove and a clamping component are provided. The connection blocks at both ends of the clamping plate two are inserted into the connection grooves at both ends of the clamping plate one. At this time, through the cooperation of the clamping component and the connection groove, the clamping plate one and the clamping plate two can be quickly installed and fixed without using bolts and other components. When dressing change is required, only the connection between the hook surface and the loop surface of the magic tape needs to be released, and then the clamping plate two is lifted upward, so that the clamping plate one and the clamping plate two can be quickly separated for quick dressing change.

[0025] 2. In the present application, an inflation assembly is provided. Through the inflated air bag, the two breathable plates and the skin-friendly cotton can be gradually pushed closer until they are closely attached to the patient's limb. At this time, the valve can be closed, so that no matter the size of the patient's limb, it can always maintain a tightened state, reducing loosening between the clamping plate one and the clamping plate two.

Detailed implementation manners

[0032] The following further elaborates on this application Figures 1-4 in further detail with reference to the accompanying drawings.

[0033] An orthopedic external fixation splint is disclosed in an embodiment of this application.

[0034] Referring to Figure 1 and Figure 2 , an orthopedic external fixation splint includes a first splint 1 and a second splint 2. Ventilation plates 4 are installed inside both the first splint 1 and the second splint 2. A skin-friendly cotton 5 is fixedly connected to one side of the ventilation plate 4. Connecting blocks 6 are fixedly connected to both ends of the second splint 2. Connecting grooves 7 are provided at both ends of the first splint 1. Clamping components 8 are symmetrically installed on both sides of the connecting block 6. Inflating components 9 are installed inside both the first splint 1 and the second splint 2. A plurality of first springs 3 are fixedly connected to the inner walls of both the first splint 1 and the second splint 2. One end of the plurality of first springs 3 is fixedly connected to one side of the ventilation plate 4. Ventilation grooves are provided between both the first splint 1 and the second splint 2 and the ventilation plate 4. A plurality of ventilation holes are evenly provided on the ventilation plate 4;

[0035] Secondly, two hook sides of Velcro 10 are symmetrically fixedly connected to the outer wall of the first splint 1, and two loop sides of Velcro 11 are symmetrically fixedly connected to the outer wall of the second splint 2.

[0036] When in use, first take out splint 1, place the patient's limb that needs to be clamped and fixed in splint 1, so that the limb is in contact with the skin-friendly cotton 5, then take out splint 2, insert the connecting blocks 6 at both ends of splint 2 into the connecting grooves 7 at both ends of splint 1, at this time, through the cooperation of the clamping assembly 8 and the connecting groove 7, splint 1 and splint 2 can be quickly installed and fixed without using bolts and other components, and then the Velcro fur surface 10 is wrapped around and adhered to the Velcro thorn surface 11 to stabilize splint 1 and splint 2 for a second time. When splint 1 and splint 2 are fixed, the inflation assembly 9 can be started to operate, and the two breathable panels can be squeezed by the operation of the inflation assembly 9. 4 drives the skin-friendly cotton 5 to fit closely with the patient's limbs, and through multiple springs 1 3, the breathable plate 4 can also continuously resist, so that the device can adapt to patients of different body shapes. Even after the swelling of the fracture site subsides, the breathable plate 4 and the skin-friendly cotton 5 can still fit with the limbs, which greatly improves the practicability of the device. Secondly, through the cooperation of the air holes and the ventilation grooves on the breathable plate 4, the overall air permeability of the device can be effectively improved, and the overall comfort of the patient is improved. In addition, when it is necessary to change the dressing, it is only necessary to release the connection between the Velcro fur surface 10 and the Velcro thorn surface 11, and then lift up the splint 2 2, so that the splint 1 1 and the splint 2 2 can be quickly separated, so as to perform a quick dressing change.

[0037] Reference Figure 1 , Figure 2 and Figure 3 The clamping assembly 8 includes limiting grooves 81 symmetrically opened on both sides of the connecting block 6, and the inside of the limiting grooves 81 is fixedly connected with springs 82, one end of the spring 82 is fixedly connected with a clamping block 83, the clamping block 83 is slidably connected in the limiting grooves 81, and one end of the clamping block 83 is arc-shaped. The inside of the connecting groove 7 has symmetrically opened grooves 71 of the same size as the arc-shaped ends of the clamping block 83.

[0038] During use, first insert the connecting blocks 6 at both ends of the splint two 2 into the connecting grooves 7 at both ends of the splint one 1. At this time, the inner wall of the connecting groove 7 will squeeze the arc end of the clamping block 83, squeezing the clamping block 83 into the limiting groove 81. When the connecting block 6 completely enters the connecting groove 7, the limiting groove 81 will be parallel to the clamping groove 71. According to the resilience of the spring two 82, it will push the clamping block 83 into the clamping groove 71. Through the mutual cooperation of the clamping block 83 and the clamping groove 71, the connecting block 6 can be clamped inside the connecting groove 7, so that the splint one 1 and the splint two 2 can be quickly installed and fixed without using bolts and other components. In addition, when it is necessary to remove and separate the splint one 1 and the splint two 2 for dressing change, just pull up the splint two 2, driving the connecting block 6 to gradually withdraw from the connecting groove 7. At this time, according to the arc end of the clamping block 83, the connection with the clamping groove 71 can be quickly released, thus releasing the connection and fixation between the splint one 1 and the splint two 2, greatly improving the removal speed between the splint one 1 and the splint two 2, and performing dressing change care more quickly.

[0039] Referring to Figure 1 , Figure 2 and Figure 4 , the inflation assembly 9 includes air bags 91 fixedly connected to the inner walls of the splint one 1 and the splint two 2. One end of the air bag 91 is fixedly connected with an air inlet pipe 92, and the other end of the air bag 91 is fixedly connected with an air outlet valve 93. One end of the air inlet pipe 92 is fixedly connected with a rubber sphere 94, and a valve 95 is fixedly connected to the air inlet pipe 92.

[0040] During use, first open the valve 95 and close the air outlet valve 93. Then, squeeze the rubber sphere 94 multiple times. By squeezing the rubber sphere 94, air can be squeezed into the air bag 91 through the air inlet pipe 92, causing the air bag 91 to gradually expand. Through the expanded air bag 91, the two breathable plates 4 and the skin-friendly cotton 5 can be pushed closer until they are in close contact with the patient's limb. At this time, the valve 95 can be closed, so that no matter the size of the patient's limb, it can always maintain a tight state, reducing the loosening of the splint one 1 and the splint two 2. Secondly, when the patient feels compression at the fracture site, the air outlet valve 93 can be opened to appropriately release some gas to reduce the expansion of the air bag 91.

[0041] The implementation principle of an orthopedic external fixation splint in this embodiment is as follows: when in use, first take out splint 1, place the patient's limb that needs to be clamped and fixed in splint 1, so that the limb is in conflict with the skin-friendly cotton 5, then take out splint 2, and insert the connecting blocks 6 at both ends of splint 2 into the connecting grooves 7 at both ends of splint 1. At this time, the inner wall of the connecting groove 7 will squeeze the arc-shaped end of the clamping block 83, and squeeze the clamping block 83 into the interior of the limiting groove 81. When the connecting block 6 completely enters the interior of the connecting groove 7, the limiting groove 81 will be parallel to the clamping groove 71, and the rebound of the spring 2 82 will push the clamping block 83 into the interior of the clamping groove 71. Through the mutual cooperation between the clamping block 83 and the clamping groove 71, the connecting block 6 can be clamped into the interior of the connecting groove 7, so that the splint 1 and the splint 2 can be quickly installed and fixed without using bolts and other components, and then the Velcro fur surface 10 is wrapped around and adhered to the Velcro The thorn surface 11 is used to perform secondary stabilization on the splint 1 and the splint 2. When the splint 1 and the splint 2 are fixed, the valve 95 can be opened to close the air outlet valve 93, and then the rubber ball 94 can be squeezed multiple times. By squeezing the rubber ball 94, air can be squeezed into the interior of the air bag 91 through the air inlet pipe 92, so that the air bag 91 gradually expands. The expanded air bag 91 can push the two air permeable plates 4 and the skin-friendly cotton 5 to gradually approach each other until they are closely fitted with the patient's limbs. At this time, the valve 95 can be closed, so that no matter how big or small the patient's limbs are, they can always be kept in a fastened state, reducing the loosening of the splint 1 and the splint 2. Secondly, when the patient feels pressure at the fracture site, the air outlet valve 93 can be opened to appropriately release some gas to reduce the expansion of the air bag 91. Even after the swelling of the fracture site is reduced, the air permeable plate 4 and the skin-friendly cotton 5 can still be fitted with the limbs, greatly improving the practicality of the device.

[0042] Secondly, through the cooperation of the air holes on the air permeable plate 4 and the ventilation grooves, the overall air permeability of the device can be effectively improved, and the overall comfort of the patient can be improved. In addition, when it is necessary to remove and separate splint 1 and splint 2 for dressing change, it is only necessary to pull splint 2 upward to drive the connecting block 6 to be gradually pulled out from the inside of the connecting groove 7. At this time, the arc-shaped end of the clamping block 83 can quickly release the connection with the clamping groove 71, thereby releasing the connection and fixation between splint 1 and splint 2, greatly improving the removal speed between splint 1 and splint 2, and performing dressing change care more quickly.
