Description

Technical Field

[0001] The present invention relates to the technical field of external bone setting, and particularly relates to a lower limb traction frame for orthopedic trauma. Background Art

[0002] During the process of external bone setting for a patient's lower limb in orthopedics, it is necessary to perform traction on the patient's limb. Traction refers to a treatment operation or surgery that uses a series of mechanical devices to straighten the fracture ends to maintain alignment and release the pressure on other skeletal systems. Traction plays an irreplaceable role before, during, and after surgical bone setting. It not only helps with fracture reduction and fixation, but also relieves pain, promotes healing, and prevents complications. At the same time, good traction care can improve the patient's comfort and rehabilitation effect. Therefore, traction is an essential and important link in the process of surgical bone setting.

[0003] Tibial fractures are common clinical fractures. Due to the strong leg muscle strength, after a patient's tibia fractures, it often shows a shortening deformity under the traction of the muscles, and it is difficult to perform intraoperative reduction, restore its length, and effectively maintain it. For tibial fractures, especially open fractures or cases with severe soft tissue injuries, external bone setting is an effective treatment option. External fixation can reduce direct damage to soft tissues, lower the risk of infection, and at the same time provide a stable fixation environment for the fracture. However, existing traction devices all straighten the lower limb, while the intramedullary nail is implanted from the proximal end of the tibia, and the patient must maintain a flexed leg position for the operation to proceed. Therefore, the present application provides a lower limb traction frame for orthopedic trauma to meet the needs. Summary of the Invention

[0011] Optionally, the connecting wire is made of steel wire, and a hook is provided at one end of the connecting wire away from the threaded rod. A connecting block is fixedly connected to one end of the connecting skeleton close to the connecting wire. A first mounting block adapted to the shape of the reinforcing rod is fixedly connected to the bottom of the connecting skeleton. A hook adapted to the shape of the connecting ring is fixedly connected to the top of the connecting skeleton.

[0012] Optionally, the connecting skeleton is made of stainless steel and is an arc-shaped structure protruding away from the first support sheet.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting the limit support mechanism and the rotation adjustment mechanism, not only can the body of the patient be limited when the medical staff performs external bone setting operations on the lower limbs of the patient, so that the patient maintains a good posture, thus facilitating the external bone setting operation, and the legs of the patient are tractioned by the rotation adjustment mechanism to be tractioned to different angles and positions, thus facilitating the external bone setting operation, and by the cooperation of the limit support mechanism and the rotation adjustment structure, the traction angle and the magnitude of the force can be further adjusted according to the specific use situation of the operation or nursing, so that the device has a better surgical treatment effect on the patient, and when the device tractiones the lower limbs of the patient, no weight is required, thus avoiding the problem that the personnel passing near the traction device accidentally touch the weight during external bone setting traction, causing it to shake or fall, thus affecting the traction effect. And the side of the first support sheet close to the reinforcing rod can support the thigh of the patient. The device can also lift the root of the thigh to the required height through the limit support mechanism, which plays an important role in lower limb traction, not only can improve the traction effect, but also can prevent various complications and promote the recovery of the patient. And the cooperation of the structures in the device can make the patient maintain a flexed leg posture during the operation, thus facilitating the operation of the medical staff and increasing the working efficiency of the surgical treatment.

[0016] By providing a second limiting block and a first limiting block inside the limiting and supporting mechanism, not only can the first limiting block and the second limiting block be installed on the bed body according to the on-site usage conditions, so as to quickly install the first supporting sheet body and the second supporting sheet body on the bed body. Then, let the patient lie on the bed body, and the contours of the patient's waist, buttocks and thighs fit against the outer wall of the top of the first supporting sheet body. The first supporting sheet body limits the position of the patient's body, so that the patient's body will not be greatly displaced due to the influence of traction force or other reasons such as the patient's body movement during the external bone setting process, thus ensuring the traction effect during the external bone setting of the patient's lower limbs. Moreover, a first buffer cavity is provided at the top of the first limiting block, and a second buffer cavity is provided at the top of the second limiting block. Due to the pressure generated by the patient's body on the first supporting sheet body and the second supporting sheet body towards the first limiting block and the second limiting block, the sides of the first limiting block close to the first buffer cavity and the second limiting block close to the second buffer cavity are compressed and deformed, so that the outer walls of the first limiting block and the second limiting block are closely attached to the inner walls of the limiting installation grooves on the bed body, thereby making the first supporting sheet body and the second supporting sheet body more stable during use. And the above structure is simple and convenient to use.

[0017] By providing a first weakening part and a second weakening part inside the rotation adjustment mechanism, not only can the part of the first supporting sheet body close to the first weakening part have a stronger deformation ability. When the patient lies on the first supporting sheet body, the first supporting sheet body can be compressed to produce a certain degree of elastic deformation, so that the first supporting sheet body can better fit the patient's body, thus playing a good limiting and supporting effect on the patient's body. And when the second supporting sheet body is under the action of an external force, it will first deform from the second weakening part, so that the distance between the second limiting block and the first limiting block installed on the bed body can be quickly adjusted, and then the convex height of the second supporting sheet body close to the convex part can be adjusted. Furthermore, the second supporting sheet body can lift one side of the first supporting sheet body close to the patient's leg to different heights, thus ensuring the surgical treatment effect. And the cooperation between the structures effectively makes the use effect of the limiting and supporting mechanism better.

[0018] By providing a connecting skeleton and a connecting wire inside the rotation adjustment mechanism, not only can the connecting skeleton be in an arc structure. When the patient's leg is set in the leg limiting sleeve, the patient's leg generates a downward traction force on the leg limiting sleeve, so that the connecting skeleton connected to the leg limiting sleeve through a hook and a connecting ring is stressed and deformed. And the restoring force generated by the deformation of the connecting skeleton plays a traction role on the patient's leg inside the leg limiting sleeve. And when the connecting skeleton tractions the patient's lower limb, the use of the connecting wire in cooperation with the connecting skeleton can also enhance the stability of the connecting skeleton and adjust the traction force magnitude of the connecting skeleton. The cooperation between the structures effectively makes the use effect of the rotation adjustment mechanism better.

[0019] By providing a threaded rod and a rotary handle inside the rotary adjustment mechanism, not only can the rotary handle be rotated to drive the threaded rod to rotate, so as to adjust the extended length of the connecting wire, and then adjust the distance between the threaded rod and the connecting block, thereby using the pulling force generated by the adjusting connecting wire on the connecting skeleton to adjust the deformation amount of the connecting skeleton. Different deformation amounts of the connecting skeleton result in different magnitudes of its restoring elastic force. Therefore, rotating the adjusting threaded rod can adjust the traction force of the connecting skeleton on the legs of the patient inside the leg limiting sleeve. And because the threaded rod is provided with an external thread, the threaded groove is provided with an external thread, and the slot penetrates through the second buffer cavity. When the threaded rod is rotated, the threaded rod is horizontally moved in the threaded groove and the slot under the threaded action of the second limiting block. After removing the rotational force applied by the user's hand to the threaded rod, the threaded locking structure formed by the second limiting block on the threaded rod prevents the threaded rod from rotating reversely under the pulling force of the connecting wire.

[0020] In summary, this device can not only achieve a good traction effect on the lower limbs of the patient through the cooperation of the limit support mechanism, the rotary adjustment mechanism and each component therein, can quickly adjust the traction angle and the traction force according to the specific on-site usage situation, and does not require the use of a weight during the traction process. Moreover, the structure of this device is simple, convenient and fast to use, the production cost of the device is low, the practicability is good, and it is convenient for popularization and use.

[0030] As Figure 1 , Figure 2 , Figure 4 and Figure 5As shown in the figure, an embodiment of the present invention provides a lower limb traction rack for orthopedic trauma, which includes a first support sheet body 1. A second support sheet body 2 is fixedly connected to the bottom of the first support sheet body 1. A bed body 24 is provided at the bottom of the first support sheet body 1. A reinforcing rod 25 is installed on one side of the bed body 24. Guardrail bodies 26 are installed on the left and right sides of the bed body 24. Limiting installation grooves are equidistantly opened on the first support sheet body 1. A leg limiting sleeve 29 is provided at the top of the first support sheet body 1. A connecting ring 30 is provided on the side of the leg limiting sleeve 29 away from the reinforcing rod 25; a limiting support mechanism is used to limit and support the patient's body and is connected to the first support sheet body 1; a rotation adjustment mechanism is used to adjust the traction force on the patient's lower limbs and is connected to the limiting support mechanism. By using the limiting support mechanism, when medical staff perform external bone connection operations on the patient's lower limbs, the patient's body can be limited, so that the patient maintains a good posture, thus facilitating external bone connection surgery operations. And through the rotation adjustment mechanism, traction is applied to the patient's legs, so that the legs are pulled to different angles and positions, thus facilitating external bone connection surgery operations. And through the cooperation of the limiting support mechanism and the rotation adjustment structure, the traction angle and force magnitude can be further adjusted according to the specific usage situation of the surgery or nursing, so that the device can achieve a better surgical treatment effect on the patient. And the structure of this device is relatively simple, and the cooperation between the structures effectively improves the work efficiency of medical staff. And when this device performs traction on the patient's lower limbs, no weights are required, thus avoiding the problem that when performing external bone connection traction, people passing by near the traction device accidentally touch the weights, causing them to shake or fall, thus affecting the traction effect.

[0031] Further, as Figure 7 shown, a first slot 27 is opened on the side of the first support sheet body 1 close to the second support sheet body 2, and a second slot 28 is opened on the side of the second support sheet body 2 close to the second support sheet body 2. When the device is used to traction one leg of the patient, the other leg is naturally placed on the first support sheet body 1 and the second support sheet body 2. The naturally placed leg is not affected by the traction force, and its natural downward force causes compressive deformation of the first support sheet body 1. Through the cooperation of the first slot 27 and the second slot 28, the naturally placed leg can only squeeze the first support sheet body 1 and the second support sheet body 2 on the side close to it, so that it will not affect the first support sheet body 1 and the second support sheet body 2 on the other side, and the first support sheet body 1 and the second support sheet body 2 have a good supporting effect on the other leg that needs to be tractioned.

[0032] As Figures 4 to 11As shown, the limit support mechanism includes first limit blocks 6 installed on both sides of the bottom of the first support sheet body 1. Second limit blocks 8 are fixedly connected to both sides of the bottom of the second support sheet body 2. A convex portion 3 is provided at the top of the side of the second support sheet body 2 close to the first support sheet body 1. A slot 11 is formed in one of the second limit blocks 8, and a threaded groove 10 is formed in the other second limit block 8. The shapes of the first limit block 6 and the second limit block 8 are adapted to the shape of the limit installation groove on the bed body 24. The shape of the first support sheet body 1 is adapted to the contour shapes of the waist, buttocks, and thighs of the patient's body. By installing the first limit block 6 and the second limit block 8 on the bed body 24 according to the on-site usage situation, the first support sheet body 1 and the second support sheet body 2 can be quickly installed on the bed body 24. Then, let the patient lie on the bed body 24. The contours of the patient's waist, buttocks, and thighs are in contact with the outer wall of the top of the first support sheet body 1. The first support sheet body 1 limits the position of the patient's body, so that the patient's body will not be greatly displaced due to the influence of traction force or other reasons such as the patient's body movement during the external bone setting process, thus ensuring the traction effect during the external bone setting of the patient's lower limbs. Moreover, the side of the first support sheet body 1 close to the strengthening rod 25 can lift the patient's thighs, which can improve the venous return of the lower limbs, reduce lower limb venous congestion, and thus relieve swelling and pain. This is particularly important for postoperative patients or patients who need traction due to fractures or joint injuries. And during the lower limb traction process, appropriately lifting the thighs can better play the role of the traction force, making the traction force more evenly distributed on the lower limbs. This is particularly important for fracture reduction or joint orthopedic treatment and can improve the treatment effect.

[0033] As Figures 4 to 11As shown, the first support sheet body 1 and the second support sheet body 2 are integrally formed. The integral structure has better stability and is convenient for production and transportation. Both the first support sheet body 1 and the second support sheet body 2 are made of plastic material. The plastic material has a light weight and good deformation ability. A first weakening part 4 is provided on the side of the first support sheet body 1 away from the second support sheet body 2, so that the part of the first support sheet body 1 near the first weakening part 4 has a stronger deformation ability. Thus, when a patient lies on the first support sheet body 1, the first support sheet body 1 can be compressed to produce a certain degree of elastic deformation, and then the first support sheet body 1 can better fit the patient's body, and further play a good limiting and supporting effect on the patient's body. A second weakening part 5 is provided on the side of the second support sheet body 2 near the convex part 3, so that the second support sheet body 2 deforms first from the second weakening part 5 under the action of an external force. Thus, by adjusting the distance between the second limit block 8 and the first limit block 6 installed on the bed body 24, the convex height of the second support sheet body 2 near the convex part 3 can be adjusted, and then the second support sheet body 2 can lift one side of the first support sheet body 1 near the patient's leg to different heights. Because different treatment goals require different elevation heights and angles, adjusting the first support sheet body 1 to an appropriate angle can ensure the safety and effect of traction. First lightening grooves 12 are equidistantly provided on the first support sheet body 1, which reduces the mass of the first support sheet body 1, enhances the deformation ability of the first support sheet body 1, and improves the air permeability of the first support sheet body 1 at the same time. Second lightening grooves 13 are equidistantly provided on the second support sheet body 2, which reduces the mass of the second support sheet body 2, enhances the deformation ability of the second support sheet body 2, and improves the air permeability of the second support sheet body 2 at the same time. A first buffer cavity 7 is provided at the top of the first limit block 6, and a second buffer cavity 9 is provided at the top of the second limit block 8. Due to the pressure generated by the patient's body on the first support sheet body 1 and the second support sheet body 2 towards the first limit block 6 and the second limit block 8, the sides of the first limit block 6 near the first buffer cavity 7 and the second limit block 8 near the second buffer cavity 9 are compressed and deformed, so that the outer walls of the first limit block 6 and the second limit block 8 are closely attached to the inner walls of the limit installation grooves on the bed body 24, and thus the stability of the first support sheet body 1 and the second support sheet body 2 during use is better.

[0034] As Figures 1 to 5 and Figures 8 to 12As shown in the figure, the rotation adjustment mechanism includes a threaded rod 22 installed in the threaded groove 10 and adapted to the shapes of the threaded groove 10 and the slot 11. On the side of the threaded rod 22 away from the second limit block 8, a turning handle 23 is fixedly connected. A groove adapted to the contour of the human hand is provided on the turning handle 23. A rotating groove adapted to the shape of the threaded rod 22 is provided on the side of the first support sheet 1 close to the turning handle 23. A connecting wire 14 is installed on the side of the threaded rod 22 close to the reinforcing rod 25. One end of the connecting wire 14 away from the threaded rod 22 is provided with a hook. A connecting skeleton 15 is installed on the side of the bed body 24 close to the reinforcing rod 25. The connecting skeleton 15 is an arc-shaped structure protruding away from the first support sheet 1. A connecting block 16 is fixedly connected to one end of the connecting skeleton 15 close to the connecting wire 14. A first mounting block 17 adapted to the shape of the reinforcing rod 25 is fixedly connected to the bottom of the connecting skeleton 15. A hook 18 adapted to the shape of the connecting ring 30 is fixedly connected to the top of the connecting skeleton 15. A second mounting block 19 is installed on the top of one guardrail body 26 close to the reinforcing rod 25. A fixing rod 20 is fixedly connected to the top of the second mounting block 19. A rotating block 21 is rotatably connected to the top of the fixing rod 20. The shape of the second mounting block 19 is adapted to the shape of the top edge frame of the guardrail body 26. The top of the connecting skeleton 15 is installed on the rotating block 21. By installing the first mounting block 17 on the reinforcing rod 25, hooking the hook 18 on the connecting ring 30, and fixing the leg limiting sleeve 29 on the patient's leg, the leg limiting sleeve 29 is an existing mature technology, and its working principle and specific structure will not be elaborated here. Then, hook the end of the connecting wire 14 away from the threaded rod 22 on the connecting block 16. Since the connecting skeleton 15 is an arc-shaped structure, when the patient's leg is placed in the leg limiting sleeve 29, a downward traction force is generated on the leg limiting sleeve 29, so that the connecting skeleton 15 connected to the leg limiting sleeve 29 through the hook 18 and the connecting ring 30 is deformed under force. The restoring force generated by the deformation of the connecting skeleton 15 plays a traction role on the patient's leg in the leg limiting sleeve 29. Since the connecting wire 14 is connected to the connecting skeleton 15 through the connecting block 16, and one end of the connecting wire 14 close to the threaded rod 22 is wound around the threaded rod 22, rotating the turning handle 23 to drive the threaded rod 22 to rotate can adjust the extended length of the connecting wire 14, and further adjust the distance between the threaded rod 22 and the connecting block 16, so as to adjust the magnitude of the pulling force generated by the connecting wire 14 on the connecting skeleton 15, and then adjust the amount of deformation of the connecting skeleton 15. Different amounts of deformation of the connecting skeleton 15 result in different magnitudes of its restoring force. Therefore, rotating and adjusting the threaded rod 22 can adjust the magnitude of the traction force of the connecting skeleton 15 on the patient's leg in the leg limiting sleeve 29. Since the threaded rod 22 is provided with external threads, and the threaded groove 10 is provided with internal threads, and the slot 11 penetrates the second buffer cavity 9, when the threaded rod 22 is rotated, the threaded rod 22 is horizontally moved in the threaded groove 10 and the slot 11 under the threaded action of the second limit block 8. After removing the rotational force applied by the user's hand to the threaded rod 22,The threaded locking structure formed by the second limiting block 8 on the threaded rod 22 prevents the threaded rod 22 from rotating in the reverse direction under the tension of the connecting wire 14. Moreover, the above structure is relatively simple, and the installation and use are very convenient and fast.

[0035] Furthermore, the connecting wire 14 is made of steel wire. The steel wire has good toughness and is not easily broken. One end of the connecting wire 14 close to the connecting block 16 is a thicker steel wire with greater hardness and is not easily bent. The end of the connecting wire 14 close to the threaded rod 22 is thinner and is more likely to bend, thus facilitating the winding of the connecting wire 14 around the threaded rod 22. The connecting skeleton 15 is made of stainless steel. The thinner stainless steel has good elastic deformation ability within the elastic range. The second mounting block 19 is equidistantly provided with lightweight grooves, which reduces the weight of the second mounting block 19 and enhances the deformation ability of the second mounting block 19. The guardrail body 26 is equidistantly provided with vertical rods. The bottom of the second mounting block 19 is equidistantly provided with limiting grooves adapted to the shapes of the vertical rods on the guardrail body 26, which enables the second mounting block 19 to adjust its mounting position according to the specific on-site use conditions, thereby adjusting the traction angle of the device on the legs of the patient in the leg limiting sleeve 29. Furthermore, it is more convenient for the device to be adapted to external bone-setting surgical operations in different situations. The rotating block 21 is provided with a limiting groove adapted to the shape of the hook 18. Through the setting of the limiting groove, the top of the connecting skeleton 15 can be stably connected to the hook 18. Thus, when adjusting the tightness of the connecting skeleton 15, the stability of the device is better, and the legs of the patient will not shake greatly. Moreover, the above structure is relatively simple, and the cooperation between the structures further improves the use effect of the rotation adjustment structure.

[0036] The working principle of the technical solution provided by the present invention is as follows: During use, first install the top of the connecting skeleton 15 on the rotating block 21. By installing the first mounting block 17 on the reinforcing rod 25, hooking the hook 18 on the connecting ring 30, and fixing the leg limiting sleeve 29 on the patient's leg. The leg limiting sleeve 29 is an existing mature technology, and its working principle and specific structure will not be elaborated here. Then, install the first limiting block 6 and the second limiting block 8 on the bed body 24 according to the on-site usage conditions to quickly install the first support sheet body 1 and the second support sheet body 2 on the bed body 24. To enhance comfort, a quilt or a nursing pad can be laid on the bed body 24, covering the first support sheet body 1 and the second support sheet body 2, but not affecting the use of the first support sheet body 1 and the second support sheet body 2. Then, let the patient lie on the bed body 24. The contours of the patient's waist, buttocks, and thighs fit against the outer wall of the top of the first support sheet body 1. The first support sheet body 1 limits the position of the patient's body, so that the patient's body will not be greatly displaced due to traction during the external bone setting process or other reasons such as the patient's body movement, thus ensuring the traction effect during the external bone setting of the patient's lower limbs. Moreover, the side of the first support sheet body 1 close to the reinforcing rod 25 can lift the patient's thighs, which can improve the venous return of the lower limbs, reduce lower limb venous congestion, and thus relieve swelling and pain. Subsequently, hook the end of the connecting wire 14 away from the threaded rod 22 on the connecting block 16. Since the connecting skeleton 15 is an arc-shaped structure, and when the connecting skeleton 15 is arranged in the leg limiting sleeve 29 on the patient's leg, it generates a downward traction force on the leg limiting sleeve 29, so that the connecting skeleton 15 connected to the leg limiting sleeve 29 through the hook 18 and the connecting ring 30 is deformed under force. The restoring elastic force generated by the deformation of the connecting skeleton 15 acts on the patient's leg in the leg limiting sleeve 29. Since the connecting wire 14 is connected to the connecting skeleton 15 through the connecting block 16, and the end of the connecting wire 14 close to the threaded rod 22 is wound around the threaded rod 22, turning the turning handle 23 to drive the threaded rod 22 to rotate can adjust the extended length of the connecting wire 14, and thus adjust the distance between the threaded rod 22 and the connecting block 16, so as to adjust the pulling force generated by the connecting wire 14 on the connecting skeleton 15, and then adjust the deformation amount of the connecting skeleton 15. Different deformation amounts of the connecting skeleton 15 result in different magnitudes of its restoring elastic force. Therefore, by adjusting the threaded rod 22, the pulling force of the connecting skeleton 15 on the patient's leg in the leg limiting sleeve 29 can be adjusted. Since the threaded rod 22 is provided with external threads, and the threaded groove 10 is provided with external threads, and the slot 11 penetrates the second buffer cavity 9, when the threaded rod 22 is rotated, the threaded rod 22 is affected by the thread action of the second limiting block 8, so that the end of the threaded rod 22 close to the second buffer cavity 9 moves in the slot 11. Therefore, after removing the rotational force applied by the user's hand to the threaded rod 22, the threaded rod 22 will not rotate in the reverse direction. The coordinated use of the structures in the device can stably traction the patient's lower limbs, thus ensuring the treatment effect of external bone setting.This is especially important for patients who have undergone surgery or who need traction due to fractures or joint injuries. In the process of lower limb traction, properly raising the thigh can better exert the traction force and make the traction force more evenly distributed in the lower limbs. This is especially important for fracture reduction or joint orthopedic treatment, which can improve the treatment effect. Furthermore, a first weakened portion 4 is provided on the side of the first support sheet 1 away from the second support sheet 2, so that the deformation ability of the part of the first support sheet 1 close to the first weakened portion 4 is relatively strong, so that when the patient lies on the first support sheet 1, the first support sheet 1 can be compressed to produce a certain degree of elastic deformation, so that the first support sheet 1 can better fit the patient's body, thereby providing a good limiting and supporting effect on the patient's body, and a second weakened portion 5 is provided on the side of the second support sheet 2 close to the raised portion 3, so that the second support sheet 2 is first deformed from the second weakened portion 5 under the action of external force, so that the height of the protrusion of the second support sheet 2 close to the raised portion 3 can be adjusted by adjusting the installation spacing between the second limiting block 8 and the first limiting block 6, so that the second support sheet 2 can lift the side of the first support sheet 1 close to the patient's leg to different heights, so that the support angle of the first support sheet 1 to the patient's leg can be adjusted, so that the operation and use of external surgical bone setting are more convenient, thereby ensuring the safety and effect of traction.
