Description

Technical Field

[0001] The invention relates to the technical field of fracture fixation, and in particular to a fixation device for limb fractures. Background Art

[0002] When a patient suffers a fracture outdoors, medical staff need to use an external fixation device to fix the patient's fracture position to prevent the patient from suffering secondary trauma during the transfer process. The above-mentioned external fixation device generally includes a high-strength plate and a strap to fix the plate to the patient's fracture position. In actual operation, medical staff generally use Velcro or straps to fix the plate to the patient's fracture position.

[0003] However, most of the existing fixation devices can generally only fix the fracture position of the leg or arm. Due to the limitation of the structure of the fixation device, it is not possible to adapt to the fixation of fractures of the arm or leg at the same time. Therefore, when an accident occurs, medical staff need to temporarily select the corresponding fixation device according to the patient's needs. The selection process will inevitably delay the treatment time, causing the patient to miss the best treatment time period. In addition, when purchasing a fixation device, the hospital needs to purchase two different types of fixation devices at the same time, which is very expensive. Secondly, most of the existing fixation devices are fixed by straps or Velcro. Although the fixation with straps is firm, the straps need to be manually wrapped by medical staff, and the fixing efficiency is low. Although the fixation with Velcro is efficient, the fixing effect is not as firm and stable as the straps. Therefore, based on the above problems, the present invention provides a fixation device for limb fractures to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a fixation device for limb fractures. By setting a fixation component, compared with the existing fixation method, not only the fixation method is simple, but also the stability is good. The fixation component can also compress the fracture position of the patient to stop bleeding according to actual conditions, and the compression force and the compression position can be adjusted, so that the device has a wider range of applications and higher practical application value. The above settings can solve the problems of low fixation efficiency of existing fixation devices during use and inability to adapt to the patient's limbs at the same time.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] Optionally, the fixing assembly includes a hanging rod hung on the outer wall of the long rod, one end of the hanging rod is fixedly connected to a first arc rod, both ends of the first arc rod are fixedly connected to the same second arc rod, the number of the first arc rod and the number of the second arc rod are two, and airbags are installed in the first arc rod and the second arc rod.

[0008] Optionally, there are two hanging rods, and the two hanging rods are fixedly connected to a same connecting rod, and the connecting rod and the hanging rod are an integrally manufactured structure.

[0009] Optionally, two first bending portions are installed on the first arc-shaped rod, the first bending portion has an outwardly protruding arc-shaped curved profile, and the first bending portion has a downward curvature.

[0010] Optionally, two second bending portions are mounted on the second arc-shaped rod, and the second bending portion has an inwardly concave arc-shaped curved profile.

[0011] Optionally, both the first arc-shaped rod and the second arc-shaped rod have arc-shaped profiles, and the first arc-shaped rod and the second arc-shaped rod are integrally manufactured structures.

[0012] Optionally, a reinforcing rib is fixedly connected between the first arc-shaped rod and the second arc-shaped rod, and a limiting rod is fixedly connected to the bottom of the first arc-shaped rod and the bottom of the second arc-shaped rod.

[0013] Optionally, one end of the first arc-shaped rod away from the hanging rod is fixedly connected to a plurality of hooks, and the size of the hooks is adapted to the size of the long rod.

[0014] Optionally, a connecting sleeve is fixedly connected to the top outer wall and the bottom outer wall of the airbag, an inflation tube is fixedly connected to one end of the airbag, and an outlet pipe is fixedly connected to the end of the airbag away from the inflation tube, and the size of the connecting sleeve is compatible with the size of the first arc rod and the second arc rod.

[0015] Optionally, the shell is made of nylon cloth, a zipper is installed at one end of the shell, avoidance grooves are opened on both side walls of the shell, and the shell is fixed to the long rod and the short rod by Velcro.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, the segmented structure adopted by the fixing device provided by the present application makes the fixing device adaptable to the fixation of fractures of the limbs at the same time, which greatly improves the scope of use of the fixing device and reduces the hospital cost investment. Moreover, by setting up a fixing component, compared with the existing fixing method, not only is the fixing method simple, but also the stability is good. The fixing component can also compress the patient's fracture position to stop bleeding according to actual conditions, and the compression force and compression position can be adjusted, so that the application scope of the device is wider and the practical application value is higher.

[0018] This fixation device has two usage states. When the device is not in use, the telescopic rod is slid into the long rod to shorten the overall length of the device for easy folding, storage and transportation. When the device needs to be used to fix the fracture position, the telescopic rod is first lengthened according to the length of the patient's limbs, and then the positions and angles of the six long rods are bent to allow the long rods to wrap around the patient's limbs. After the position of the long rod is determined, the two ends of the long rod are locked and fixed with the help of the fixing assembly to keep the long rod in a bent state, thereby fixing the patient's fracture position with the help of the long rod.

[0019] By setting the hanging rod and the connecting rod, not only can the first arc rod and the long rod be disassembled and assembled at will, but the disassembly and assembly of the first arc rod is also very convenient and efficient. Secondly, the hanging rod and the connecting rod are an integrally formed structure, which reduces the production cost and improves the convenience of operation without affecting the structural strength.

[0020] By setting up an airbag, after the airbag is inflated, it can compress the first arc rod and the second arc rod, so that the distance between the first arc rod and the second arc rod becomes larger. This setting can simultaneously use the second arc rod and the airbag to compress the patient's fracture position. During the compression process, the patient's affected area can be compressed to stop bleeding, thereby improving the treatment effect.

[0021] By setting the first bending portion and the second bending portion, when the device is hit or shaken violently, the first arc rod and the second arc rod will be deformed at the positions of the first bending portion and the second bending portion respectively, and absorb the force generated by the impact and the violent shaking during the deformation process, thereby preventing the impact force from directly acting on the patient's fracture position, thereby protecting the patient's fracture position. The position of the airbag connecting sleeve is between the two first bending portions on the first arc rod and between the two second bending portions on the second arc rod. Since the first bending portion and the second bending portion both have an arc-shaped bending profile, the connecting sleeve can be limited by the first bending portion and the second bending portion, thereby preventing the airbag from sliding and dislocating.

[0044] like Figures 1 to 6As shown, an embodiment of the present invention provides a fixation device for limb fractures, including a shell 1, a long rod 2 is inserted into the shell 1, both ends of the long rod 2 are screwed with T-shaped connecting blocks 3, short rods 4 are installed on both sides of the T-shaped connecting block 3, both ends of the short rod 4 are screwed with threaded sleeves, the short rod 4 and the T-shaped connecting block 3 are rotatably connected through the threaded sleeves, the number of long rods 2 is six, a telescopic rod 201 is inserted into the long rod 2, a sliding groove 203 is provided on the telescopic rod 201, a slider 202 is fixedly connected to the inner wall of the long rod 2, the shell 1 is made of nylon cloth, a zipper 102 is installed at one end of the shell 1 to facilitate the user to open the shell 1 and take out the long rod 2 and the short rod 4 from the shell 1, and avoidance grooves 101 are provided on both side walls of the shell 1 The shell 1 is fixed to the long rod 2 and the short rod 4 by Velcro; a fixing component, the fixing component is used to fix the fracture position of the patient, the fixing component is connected to the long rod 2, and the segmented structure adopted by the fixing device provided in the present application makes the fixing device adaptable to the fracture fixation of the limbs at the same time, which greatly improves the scope of use of the fixing device and reduces the investment cost of the hospital. Moreover, by setting the fixing component, compared with the existing fixing method, not only the fixing method is simple, but also the stability is good. The fixing component can also compress the fracture position of the patient according to the actual situation to stop bleeding, and the compression force and the compression position can be adjusted, so that the application range of the device is wider and the practical application value is higher.

[0045] Specifically, the fixation device mainly relies on the long rod 2 and the short rod 4 to constrain and fix the fracture position of the patient. The long rod 2 and the short rod 4 are both stainless steel tubes. The stainless steel material is not only high in strength but also not easy to rust. The six long rods 2 are connected to each other through the T-shaped connecting block 3 and the short rod 4. The T-shaped connecting block 3 is a "T"-shaped structure, so it has three connection points. The connection point of the T-shaped connecting block 3 at the middle position is used to install the long rod 2, and the installation method is threaded connection. The connection points on both sides of the T-shaped connecting block 3 are used to install two short rods 4. The two short rods 4 are rotatably connected to the T-shaped connecting block 3 through a threaded sleeve. The short rod 4 and the threaded sleeve are threadedly connected. Through the setting of the above structure, each long rod 2 can rotate with each other. In addition, the middle position of the long rod 2 is a disconnected structure. The long rod at the disconnected position 2 is divided into two parts, one of which is fixedly connected to the telescopic rod 201, and the other is provided with a groove body that matches the size of the telescopic rod 201. The telescopic rod 201 can slide in the groove body, so the user can change the overall length of the long rod 2 by sliding the telescopic rod 201. The telescopic rod 201 and the long rod 2 are limited by the slider 202 and the slide groove 203, so as to ensure that the two disconnected long rods 2 will not rotate or misalign with each other. Since the material of the shell 1 is nylon cloth, when the user slides the telescopic rod 201 inward, the shell 1 can be folded up for easy storage. When the long rod 2 is used to fix the fracture, the telescopic rod 201 is pulled outward to extend the long rod 2. Since the shell 1 is sleeved outside the long rod 2, the telescopic rod 201 will not be separated from the telescopic rod 201 and disconnected under the limiting effect of the shell 1.

[0046] In summary, the fixation device has two use states. When the device is not in use, the telescopic rod 201 is slid into the long rod 2 to shorten the overall length of the device for easy folding, storage and transportation. When the device needs to be used to fix the fracture position, the telescopic rod 201 is first extended according to the length of the patient's limbs, and then the positions and angles of the six long rods 2 are bent (such as Figure 3 As shown), the long rod 2 is wrapped around the patient's limb. After the position of the long rod 2 is determined, the two ends of the long rod 2 are locked and fixed with the help of a fixing assembly to keep the long rod 2 in a bent state, thereby fixing the fracture position of the patient with the help of the long rod 2.

[0047] As an implementation method in this embodiment, Figures 1 to 5 and Figures 10 to 13As shown, the fixing assembly includes a hanging rod 506 hung on the outer wall of the long rod 2, one end of the hanging rod 506 is fixedly connected to the first arc rod 5, both ends of the first arc rod 5 are fixedly connected to the same second arc rod 501, the number of the first arc rod 5 and the second arc rod 501 are both two, air bags 6 are installed in the first arc rod 5 and the second arc rod 501, the number of hanging rods 506 is two, the two hanging rods 506 are fixedly connected to the same connecting rod 507, the connecting rod 507 and the hanging rod 506 are an integrally manufactured structure, the first arc rod 5 and the second arc rod 501 are an integrally manufactured structure, a reinforcing rib 504 is fixedly connected between the first arc rod 5 and the second arc rod 501, the bottom of the first arc rod 5 and the second arc rod 501 are fixedly connected to the limiting rod 505, and the first arc rod 5 is away from the hanging rod 506. A plurality of hooks 508 are fixedly connected to one end, and the size of the hooks 508 is adapted to the size of the long rod 2. In order to improve the fixing efficiency of the long rod 2, the fixing component provided in the present application mainly includes a first arc rod 5, a second arc rod 501 and an airbag 6, wherein the first arc rod 5 and the second arc rod 501 are integrally manufactured steel pipe structures, and in the actual production process, the first arc rod 5 and the second arc rod 501 are integrally bent into shape by a bending machine, and both have arc-shaped contours, wherein the size of the first arc rod 5 is larger than that of the second arc rod 501, so the first arc rod 5 is located on the outside of the second arc rod 501, and the number of the first arc rod 5 and the second arc rod 501 are both two, and the two first arc rods 5 and the second arc rod 501 are connected and fixed together by reinforcing ribs 504 and limit rods 505.

[0048] Specifically, two hanging rods 506 are installed at one end of the first arc rod 5, and one end of the two hanging rods 506 are connected together by the same connecting rod 507, wherein the hanging rod 506 and the connecting rod 507 are an integrally manufactured structure, and in the actual production process, they can also be integrally bent by a bending machine. The hanging rod 506 is a hook-shaped structure, and the connecting position of the hanging rod 506 and the connecting rod 507 has a tendency to be concave inward. Such a setting allows the user to hang the first arc rod 5 on the outer wall of the long rod 2 with the help of the hook-shaped contour of the hanging rod 506, and clamp the hanging rod 506 with the help of the concave tendency of the connecting position of the hanging rod 506 and the connecting rod 507, thereby ensuring that the hanging rod 506 will not separate from the long rod 2. The reason why two hanging rods 506 are used to hang and fix the first arc rod 5 is to improve the first arc rod The structural strength of the connection position between 5 and the long rod 2 prevents the hanging rod 506 from being deformed during long-term use of the device, thereby affecting the fixing effect of the first arc rod 5. Secondly, since the two hanging rods 506 are connected together by the connecting rod 507, when the user uses the hanging rod 506 to hang and fix the first arc rod 5, the user only needs to pry the connecting rod 507 outward to pry the two hanging rods 506 apart at the same time, thereby saving material costs and improving the efficiency of the arrangement of the hanging rods 506. In summary, by setting the hanging rod 506 and the connecting rod 507, not only can the first arc rod 5 and the long rod 2 be freely disassembled and assembled, but the first arc rod 5 is also very convenient and efficient to disassemble and assemble. Secondly, the hanging rod 506 and the connecting rod 507 are an integrally formed structure, which reduces the production cost and improves the convenience of operation without affecting the structural strength.

[0049] When it is necessary to fix the long rods 2 on both sides of the device with the help of the first arc rod 5 and the second arc rod 501, firstly, the first arc rod 5 is hung and fixed on the long rod 2 on one side of the device with the help of the hanging rod 506, and then the first arc rod 5 is fixed to the long rod 2 on the other side of the device with the help of the hook 508, so as to achieve the fixing effect of the long rods 2 on both sides of the device. Since multiple hooks 508 are arranged on the first arc rod 5, the user can choose to hang the hooks 508 at different positions on the long rod 2, so as to change the pressure of the first arc rod 5 on the patient's limbs, so as to make the device suitable for limbs of different sizes. It is worth mentioning that by arranging a reinforcing rib 504 between the first arc rod 5 and the second arc rod 501, the strength of the structure between the two can be effectively guaranteed, and the misalignment and deformation between the first arc rod 5 and the second arc rod 501 can be prevented.

[0050] In this embodiment, if Figures 1 to 5 and Figures 10 to 13As shown, two first bending portions 502 are installed on the first arc rod 5, and the first bending portion 502 has an arc-shaped bending profile that bulges outward, and the first bending portion 502 has an arc that bends downward, and two second bending portions 503 are installed on the second arc rod 501, and the second bending portion 503 has an arc-shaped bending profile that is recessed inward, and the first arc rod 5 and the second arc rod 501 are both arc-shaped profiles, and a connecting sleeve 601 is fixedly connected to the top outer wall and the bottom outer wall of the airbag 6, and one end of the airbag 6 is fixedly connected to the inflation tube 602, and the end of the airbag 6 away from the inflation tube 602 is fixedly connected to the outlet pipe 603, and the size of the connecting sleeve 601 is adapted to the size of the first arc rod 5 and the second arc rod 501. Since the first bending portion 502 and the second bending portion 503 both have arc-shaped bending profiles, Both the first arc rod 5 and the second arc rod 501 have certain elastic properties. After the user locks and fixes the long rod 2 with the help of the first arc rod 5 and the second arc rod 501, the medical staff needs to carry the patient. During the transportation process, the patient's fracture position is prone to secondary trauma due to impact and strong shaking, which requires the fixing device to have a certain buffering effect. Since the first arc rod 5 and the second arc rod 501 have certain elastic properties, when the device is impacted or shaken violently, the first arc rod 5 and the second arc rod 501 will be deformed at the positions of the first bending portion 502 and the second bending portion 503 respectively, and absorb the force generated by the impact and strong shaking during the deformation process, preventing the impact force from directly acting on the patient's fracture position, thereby protecting the patient's fracture position.

[0051] Further, the airbag 6 is installed between the first arc rod 5 and the second arc rod 501, and the airbag 6 and the first arc rod 5 and the second arc rod 501 are fixed by a connecting sleeve 601, wherein the connecting sleeve 601 is located between the two first bending portions 502 on the first arc rod 5 and between the two second bending portions 503 on the second arc rod 501. Since the first bending portion 502 and the second bending portion 503 both have arc-shaped curved profiles, the connecting sleeve 601 can be limited by the first bending portion 502 and the second bending portion 503, thereby preventing the airbag 6 from sliding and dislocating. Secondly, the bulging profile of the airbag 6 after inflation is consistent with the first arc rod 5 and the second arc rod The contours of 501 are adapted to each other, so the first arc rod 5 and the second arc rod 501 can be used to assist in limiting the airbag 6, thereby further improving the stability of the airbag 6. The above structural setting can effectively ensure that the airbag 6 is deformed into a specified shape after inflation, and will not be misplaced during deformation and use. After the airbag 6 is inflated, the first arc rod 5 and the second arc rod 501 can be compressed, thereby increasing the distance between the first arc rod 5 and the second arc rod 501. Such a setting can simultaneously compress the patient's fracture position with the help of the second arc rod 501 and the airbag 6. During the compression process, the patient's affected area can be compressed to stop bleeding, thereby improving the treatment effect.

[0052] Furthermore, since the first bending portion 502 has an outwardly convex arc-shaped curved profile and the first bending portion 502 has a downward curvature, the first bending portion 502 can wrap the top of the airbag 6 to limit it. Such a limiting method can further improve the stability of the airbag 6 and enable the airbag 6 to bulge according to the contours of the first arc-shaped rod 5 and the second arc-shaped rod 501 during the expansion process, so as to better adapt to the patient's limbs and improve the compression effect on the affected area. The second bending portion 503 has an inwardly concave arc-shaped curved profile. Since the bending directions of the first bending portion 502 and the second bending portion 503 are opposite, the airbag 6 can be limited from two different directions, thereby further ensuring the stability of the airbag 6 structure. Regardless of whether the airbag 6 is in an inflated or non-inflated state, it can cooperate with the first arc-shaped rod 5 and the second arc-shaped rod 501 to be firm and stable.

[0053] The working principle of the technical solution provided by the present invention is as follows:

[0054] When it is necessary to fix the patient's limbs, the telescopic rod 201 is first extended according to the length of the patient's limbs, and then the positions and angles of the six long rods 2 are bent to allow the long rods 2 to wrap around the patient's limbs. After the position of the long rod 2 is determined, the first arc rod 5 is first hung and fixed on the long rod 2 on one side of the device with the help of the hanging rod 506. The user hangs the first arc rod 5 on the outer wall of the long rod 2 with the help of the hook-shaped contour of the hanging rod 506, and clamps and fixes the hanging rod 506 with the help of the concave trend at the connection position of the hanging rod 506 and the connecting rod 507, thereby ensuring that the hanging rod 506 will not separate from the long rod 2. Since the two hanging rods 506 are connected together by the connecting rod 507, when the user uses the hanging rod 506 to hang and fix the first arc rod 5, the user only needs to bend the connecting rod 507 outward to simultaneously fix the two hanging rods. 506 is broken apart, thereby saving material costs and improving the efficiency of arranging the hanging rod 506. In addition, an avoidance groove 101 is opened on the shell 1, so the user can slide and adjust the positions of the first arc rod 5 and the second arc rod 501 in the avoidance groove 101, so as to more accurately fix the patient's fracture position. After the user fixes the first arc rod 5 and the second arc rod 501 on the long rod 2, the first arc rod 5 is fixed to the long rod 2 on the other side of the device with the help of the hook 508, so as to achieve the fixing effect of the long rod 2 on both sides of the device. Since a plurality of hooks 508 are arranged on the first arc rod 5, the user can choose to let the hooks 508 in different positions be hung on the long rod 2, so as to change the pressure of the first arc rod 5 on the patient's limbs, so as to make the device suitable for limbs of different sizes.

[0055] Since the first bending portion 502 and the second bending portion 503 both have an arc-shaped curved profile, the first arc rod 5 and the second arc rod 501 both have certain elastic properties. When the device is hit or shaken violently, the first arc rod 5 and the second arc rod 501 will deform at the positions of the first bending portion 502 and the second bending portion 503 respectively, and absorb the force generated by the impact and violent shaking during the deformation process, preventing the impact force from directly acting on the patient's fracture position, thereby protecting the patient's fracture position.

[0056] The airbag 6 is installed between the first arc rod 5 and the second arc rod 501, and the airbag 6 and the first arc rod 5 and the second arc rod 501 are fixed by a connecting sleeve 601, wherein the connecting sleeve 601 is located between the two first bending portions 502 on the first arc rod 5 and between the two second bending portions 503 on the second arc rod 501. Since the first bending portion 502 and the second bending portion 503 both have an arc-shaped curved profile, the connecting sleeve 601 can be limited by the first bending portion 502 and the second bending portion 503, thereby preventing the airbag 6 from sliding and dislocating. After being inflated, the airbag 6 can compress the first arc rod 5 and the second arc rod 501, thereby increasing the distance between the first arc rod 5 and the second arc rod 501. Such a setting can compress the fracture position of the patient with the help of the second arc rod 501 and the airbag 6 at the same time. During the compression process, the affected part of the patient can be compressed and hemostasis can be achieved, thereby improving the treatment effect.
