Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a wound site supporting device for orthopedic wounds. Background Art

[0002] Plaster fixation is a commonly used clinical treatment or auxiliary treatment method for fractures, joint injuries, joint dislocations and other diseases. The purpose of treatment is achieved by resetting the injured part and then maintaining a certain stability through plaster fixation. It is of great significance for the treatment or auxiliary treatment of limb fractures, joint injuries, deformity correction and other problems. Compared with other external fixation methods, this operation is simple and non-invasive. The patient feels less discomfort and has fewer adverse effects during the operation. It is relatively simple and easy to operate and has a wide range of clinical applications. After the fracture is fixed with plaster, the leg should be raised as high as possible, which is conducive to blood return and accelerates the swelling of the limb. At present, after plaster fixation, the leg is generally placed on a tripod for support, but this method does not fix the patient's leg firmly, and the position and angle of the support cannot be adjusted, which makes the patient very uncomfortable, especially when the patient's leg and the weight of the plaster act, it is impossible to support it more forcefully. Long-term uncoordinated support will create a risk of damage to the device.

[0003] The patent with publication number CN212490525U discloses a general surgery postoperative lower limb rehabilitation nursing support, including: a U-shaped plate, a telescopic sleeve, a hinged rod, a first handle bolt, a threaded sleeve, a second handle bolt, a threaded rod, a mounting base, a linear slide and a support plate. The U-shaped plate is distributed at both ends of the telescopic sleeve and fastened with screws. The hinged rod is hinged to the left and right ends of the telescopic sleeve and fastened by the first handle bolt. The threaded sleeve is hinged to the hinged rod and fastened by the second handle bolt. The threaded rod The thread is connected to the threaded sleeve, the mounting base is movably mounted on the top of the threaded rod, the linear slide is fixedly mounted on the mounting base, and the support plate is fixedly mounted on the moving block of the linear slide. When in use, the patient's lower limbs are placed on the support plate, and the support plate can be relatively raised and lowered by the threaded sleeve and the threaded rod. At the same time, under the action of the linear slide, the support plate can be moved laterally, thereby changing the different positions of the patient's lower limbs. It is especially suitable for patients with leg fractures and plaster casts who are suspended for a long time, and can be adjusted according to the patient's habits.

[0004] The bracket provided by the above technical solution has a complex structure and occupies a large space on the bed. After the patient's lower limbs are suspended, the bracket needs to be removed first, and then other medical staff need to assist in supporting the patient's lower limbs and slowly placing the patient's lower limbs on the bed, which is very inconvenient to use. In addition, the above technical solution uses an articulated rod to support the mounting base under the pallet. When the patient places his lower limbs on the pallet, the patient's lower limbs exert pressure on the articulated rod through the mounting base, which causes high stress at both ends of the articulated rod. If used for a long time, the wear of the two ends of the articulated rod will increase, thereby greatly reducing the overall service life of the bracket. Summary of the Invention

[0005] The purpose of the present invention is to overcome the problems of the existing bracket being inconvenient to use and having a short service life.

[0010] The support adjustment mechanism is used to increase the support force of the support shaft to prevent deformation caused by excessive stress on the support shaft. In a further limitation of the above technical solution, each support adjustment mechanism includes: The second screw is located in the corresponding square hole, and the upper end of the second screw is connected to the corresponding support shaft, and the lower end of the second screw passes through the H-shaped moving block and is located below the H-shaped moving block; The tension spring has an upper end connected to the side wall of the square hole of the H-shaped moving block, and a lower end connected to the corresponding support shaft.

[0011] In order to more accurately place the suspension mechanism directly above the patient, the above technical solution is further limited, and the lateral adjustment mechanism includes: Two third screws are respectively rotatably connected to one side of the horizontal plate away from the rotating tube; A synchronous belt is connected to the two third screws respectively; The third rotating handle is arranged between the two third screw rods and is connected to the synchronous belt.

[0012] The above technical solution is further limited in that the mounting block is a T-shaped structure and is rotatably connected to the rotating tube.

[0013] The above technical solution is further limited in that the mounting block is further provided with a first rotating handle rotatably connected to the rotating tube.

[0014] Since the patient's lower limbs are wrapped in plaster, in order to prevent the patient's lower limbs from moving when the upper limbs move, the above technical solution is further limited to provide a clamping mechanism on the suspension mechanism to prevent the patient's lower limbs from moving.

Beneficial effects

[0018] 1. The present invention combines the arrangement of a rotating tube, a suspension mechanism, a horizontal plate and a height adjustment mechanism. Medical personnel only need to rotate the first rotating handle to rotate the horizontal plate arranged on the rotating tube to above the patient so that the patient's legs can be placed on the suspension mechanism. The height adjustment mechanism can not only adjust the height of the suspension mechanism by adjusting the angle between the horizontal plate and the rotating tube, but also, after the patient has finished using the bed, only the second rotating handle and the third rotating handle need to be rotated to lower the height of the suspension mechanism until the patient's lower limbs are parallel to the bed surface so that the patient's suspended lower limbs can be placed on the bed surface. The operation is simple and easy to use.

Finally, the clamping blocks can be fixed with fixing bolts. The operation is simple and convenient, and it can prevent the patient's lower limbs from moving when the upper limbs move, thereby ensuring the suspension effect of the patient's lower limbs.

[0021] 4. The present invention combines a stabilizing rod, a support rod and a suspension mechanism. After the patient's legs are placed on the suspension mechanism, the stabilizing rod provides a horizontal pulling force to the suspension mechanism through a stabilizing spring to prevent the suspension device from swinging back and forth significantly under the action of the ball joint.

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] In the description of the present invention, it should be understood that the terms "length direction", "up", "down", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they cannot be understood as limitations on the present invention. In addition, features limited to "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0027] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0028] The inventors have found that 1. The current bracket has a complex structure and occupies a large space on the bed. After the patient's lower limbs are suspended, the bracket needs to be removed first, and then other medical staff need to assist in supporting the patient's lower limbs and slowly placing the patient's lower limbs on the bed, which is very inconvenient to use; 2. The above technical solution uses a hinged rod to provide support for the mounting base under the pallet. When the patient places the lower limbs on the pallet, the patient's lower limbs exert pressure on the hinged rod through the mounting base, which causes high stress at both ends of the hinged rod. If used for a long time, the wear of the two ends of the hinged rod will increase, thereby greatly reducing the overall service life of the bracket; 3. The current support components used to support the patient's lower limbs cannot be applied to patients of different body shapes. If the patient's upper body moves, the lower limbs will be driven to move, and there is a risk of falling from the bracket.

[0029] Based on the above findings, the present application provides a trauma support device for orthopedic trauma fixed to the side of a bed board, comprising a rotating tube 1, a horizontal plate 2, a suspension mechanism 3, a height adjustment mechanism 4, and a support adjustment mechanism 5; wherein the horizontal plate 2 is connected to the rotating tube 1 and the suspension mechanism 3, respectively, the height adjustment mechanism 4 is provided at the connection between the horizontal plate 2 and the rotating tube 1, and the support adjustment structure 5 is provided on the height adjustment mechanism 4; during use, only one medical staff member is required to adjust the height of the suspension mechanism 3 through the height adjustment mechanism 4, thereby adjusting the height of the patient's lower limb. Moreover, after use, there is no need for multiple medical staff members to assist in supporting the patient's lower limb, and the use is simple and convenient; 2. A support adjustment mechanism 5 is provided on the height adjustment mechanism 4 to provide support for the connection between the horizontal plate 2 and the rotating tube 1, thereby preventing the horizontal plate 2 from tilting downward due to pressure from the patient's lower limbs, thereby reducing stress at the connection between the horizontal plate 2 and the rotating tube 1, reducing wear at the connection between the horizontal plate 2 and the rotating tube 1, and extending the service life of the entire device; 3. A clamping mechanism 9 is added to the suspension mechanism 3 to clamp the legs of patients with different body shapes, preventing the lower limbs from moving during the movement of the patient's upper limbs, thereby ensuring the suspension effect of the patient's lower limbs.

[0030] Example 1 This embodiment provides a trauma site support device for orthopedic trauma, such as Figure 1-16 As shown, it includes a rotating tube 1, a horizontal plate 2, a suspension mechanism 3, a height adjustment mechanism 4, a lateral adjustment mechanism 6 and a clamping mechanism 9; wherein, a support adjustment mechanism 5 is symmetrically provided on both sides of the height adjustment mechanism 4.

[0031] The rotating tube 1 is a cylindrical structure with a circular groove at its center for connection with the height adjustment mechanism 4 .

[0032] The mounting block 7 is located at the lower end of the rotating tube 1. After the lower end of the rotating tube 1 passes through the mounting block 7, it engages with a first rotating handle 8 provided on the side of the mounting block 7. The first rotating handle 8 is provided with a bevel gear at the end closest to the rotating tube 1. Correspondingly, the lower end of the rotating tube 1 is provided with a gear that engages with the bevel gear. Specifically, a groove is provided below the mounting block 7 for engaging with the bed frame. During actual use, medical staff can use this groove to secure the mounting block 7 to the side of the bed frame. The end of the groove of the mounting block 7 is provided with a fixing hole to allow the mounting block 7 to be fixed with bolts to prevent the mounting block 7 from shaking.

[0033] It should be noted that the embodiment of the present invention does not limit the direction of the groove of the mounting block 7 for engaging with the bed body. For example, the embodiment of the present invention is described as an example in which the groove opening on the mounting block 7 is downward.

[0034] In actual use, the first rotating handle 8 can be rotated to drive the rotating tube 1 to rotate, and then the rotating tube 1 drives the horizontal plate 2 to rotate in the horizontal direction with the rotating tube 1 as the center, so that the horizontal plate 2 is located above the patient.

[0035] The horizontal plate 2 is mounted on the upper end of the rotating tube 1 and is rotatably connected to the upper end of the rotating tube 1. Specifically, the horizontal plate 2 is a sheet-like structure, and a first chute 21 is provided in the middle of the horizontal plate 2 to facilitate the sliding of the suspension mechanism 3. Second chute 22 is provided on either side of the first chute 21 to facilitate connection with the two support adjustment mechanisms 5. In actual use, the suspension mechanism 3 is slidably connected to the first chute 21 via a sliding connector 31.

[0036] Specifically, such as Figure 1 and Figure 6 As shown, the sliding connector 31 is an inverted T-shaped rod structure. A sliding piece is provided at the upper end of the sliding connector 31, which is positioned within the first sliding groove 21. A ball joint is provided at the lower end of the sliding connector 31, which is rotatably connected to the connecting rod provided on the suspension mechanism 3. The sliding piece of the sliding connector 31 is provided with two threaded through holes for connection to the lateral adjustment mechanism 6.

[0037] Among them, such as Figure 12 As shown, the suspension mechanism 3 is a U-shaped structure with a connector for connecting to a ball joint located above the U-shaped structure. During use, the suspension mechanism 3 is connected to the ball joint via the connector. This allows the suspension mechanism 3 to rotate 360 degrees, providing support for the orthopedic trauma site of the patient's lower limb and conforming to the plaster surface of the patient's lower limb.

[0038] like Figure 10As shown, the lateral adjustment mechanism 6 is arranged at the end of the horizontal plate 2 away from the rotating tube; the lateral adjustment mechanism 6 includes a third screw 61, a synchronous belt 62 and a third rotating handle 63; wherein, the number of the third screws 61 is two, and the two third screws 61 are symmetrically arranged on both sides of the third rotating handle 63.

[0039] Specifically, one end of each third screw 61 penetrates into the interior of the transverse plate 2 and is rotatably connected to the corresponding threaded hole on the sliding plate in the sliding connector 31; the other end of each third screw 61 is located outside the transverse plate 61 and is meshed with the synchronous belt 2.

[0040] The third rotating handle 63 is rotatably connected to the side surface of the transverse plate 2 and is meshed with the synchronous belt 62 .

[0041] During use, medical staff can rotate the third rotating handle 63 to drive the synchronous belt 62 to rotate, and then the synchronous belt 62 drives the two third screws 61 to rotate, and then the two third screws 61 drive the sliding plate in the sliding connection 31 to slide in the first sliding groove 21, thereby realizing the adjustment of the suspension mechanism 3 in the length direction of the horizontal plate 2.

[0042] In practical applications, in order to prevent the suspension mechanism 3 from shaking significantly under the connection of the ball joint after the patient's upper limb is placed on the suspension mechanism 3, as shown in FIG. Figure 3 As shown, a stabilizing rod 32 is further provided on the side of the suspension mechanism 3; The stabilizing rod 32 includes a movable rod 32a, a sleeve 32b, and a stabilizing spring 32c. Specifically, one end of the movable rod 32a is rotatably connected to the side of the suspension mechanism 3, and the other end is sleeved with the sleeve 32b. The stabilizing spring 32c is disposed within the sleeve 32b, and one end of the stabilizing spring 32c is fixedly connected to the inner bottom surface of the sleeve 32b, while the other end is fixedly connected to the end of the movable rod 32a away from the suspension mechanism 3. In this way, after the patient's legs are placed on the suspension mechanism 3, the suspension mechanism 3 is in a vertical position under the action of the patient's legs' weight. At this time, the movable rod 32a is pulled out, and the stabilizing spring 32c provides tension to the movable rod 32a, preventing the suspension mechanism 3 from shaking widely.

[0043] In order to facilitate the adjustment of the height of the patient's lower limbs, Figure 6 and Figure 9 As shown, the height adjustment mechanism 4 includes a first screw 41, a second rotating handle 45, an H-shaped moving block 42, and support rods 43 symmetrically arranged on both sides of the H-shaped moving block 42; The upper end of each support rod 43 is located in the corresponding second slide groove 22 on the horizontal plate 2 and is rotatably connected to the horizontal plate 2 via a rotating rod. The lower end of each support rod 43 is rotatably connected to a support shaft 44, which is located in the square through-hole of the H-shaped moving block 42. The outer side of the support rod 44 is provided with an elastic layer, which is used to cooperate with the support adjustment mechanism 5.

[0044] The first screw rod 41 is located in the circular groove of the rotating tube 1. The upper end of the first screw rod 41 is fixedly connected to the second rotating handle 45, and the lower end of the first screw rod 41 is rotatably connected to the bottom surface of the rotating tube 1. The side surface of the rotating tube 1 is also symmetrically provided with strip-shaped through holes to allow the H-shaped moving block 42 to pass through.

[0045] The H-shaped moving block 42 is sleeved on the first screw rod 41 , and both ends of the H-shaped moving block 42 respectively pass through the strip-shaped through holes of the rotating tube 1 and are located outside the rotating tube 1 .

[0046] During actual use, the medical staff rotates the second rotating handle 45, and the second rotating handle 45 drives the first screw 41 to rotate. After the H-shaped moving block 42 is limited by the bar-shaped through hole of the rotating tube 1, it moves up and down under the drive of the first screw 41, and then the support rod 43 connected to the H-shaped moving block 42 moves upward with the H-shaped moving block 42, so that the cross plate 2 rotates on the vertical plane with the upper end of the rotating tube 1 as the center, so as to realize the height adjustment of the suspension mechanism 3.

[0047] Specifically, two square grooves are symmetrically provided on the side surface of the H-shaped moving block 42 . When in use, the two support shafts 44 are respectively provided in the corresponding direction grooves and connected to the corresponding support adjustment mechanisms 5 .

[0048] Each support adjustment mechanism 5 includes a second screw 51 , a tension spring 52 , and a plurality of adjustment holes 53 that are connected to each other and are provided on the H-shaped moving block 42 .

[0049] The upper end of the second screw rod 51 passes through the bottom surface of the H-shaped moving block 42 and is fixedly connected to the corresponding support shaft 44 .

[0050] The upper end of the tension spring 52 is fixedly connected to the top surface of the square groove of the H-shaped moving block 42 , and the lower end is fixedly connected to the side surface of the support shaft 44 .

[0051] In actual application, the two ends of each support shaft 44 are respectively located in the corresponding adjustment hole 53, so that medical staff can rotate the second screw rod 51 to adjust the height of the support shaft 44. In the process of the support shaft 44 moving up and down, the elastic layer sleeved on the support shaft 44 is squeezed by the inner wall of the adjustment hole 53 and enters the adjustment hole 53 adjacent to it above or below. At this time, the elastic layer sleeved on the support shaft 44 returns to its natural state. In this way, the support shaft 44 is supported by the upward support force of the second threaded rod 51, and is also limited by the inner wall of the adjustment hole 53 on the support shaft 44, further preventing the support shaft 44 from moving; not only that, the tension spring 53 continuously applies an upward pulling force to the support shaft 44, further preventing the support shaft 44 from moving downward after being subjected to the downward pressure of the support rod 43.

[0052] In this way, the setting of the adjustment hole 53 can prevent the H-shaped moving block 42 from receiving excessive stress and moving downward after the support shaft 44 is subjected to downward pressure from the support rod 43. At this time, even if the support shaft 44 is subjected to excessive downward pressure from the support rod 43, causing the support shaft 44 to move downward, the setting of the adjustment hole 53 can prevent the support shaft 44 from continuing to move downward, and the supporting force of the support shaft 44 can be increased by the setting of the second screw 51 and the tension spring 52, thereby reducing the loss of the support shaft 44 and extending the service life of the entire device.

[0053] The suspension mechanism 3 is also provided with a clamping mechanism 9 for preventing the patient's lower limbs from moving during the patient's upper body movements. Figure 3 As shown, the clamping mechanism 9 includes: two clamping blocks 91 , a support airbag 92 arranged between the two clamping blocks 91 , an inflation pipeline 93 and two sets of fixing bolts 94 ; wherein, the inflation pipeline 93 is embedded in the suspension mechanism 3 .

[0054] Two clamping blocks 91 are respectively arranged on both sides of the suspension mechanism 3, and a guide rod 95 is provided on one side of each clamping block 91. Specifically, one end of the guide rod 95 is fixedly connected to the corresponding clamping block 91, and the other end is located on the outside after passing through the side of the suspension mechanism 3, so as to prevent the clamping block 91 from rotating during the clamping process; wherein, an anti-slip block is provided at the end of the guide rod 95 away from the clamping block 91, and the anti-slip block is used to prevent the guide rod 95 from sliding off the suspension mechanism 3, and a plurality of linearly arranged limiting holes are provided on the side of each guide rod 95, and the plurality of limiting holes are used to be plugged with the fixing bolts 94 to fix the position of the clamping block 91, prevent the patient from moving around and then deflate the support airbag 92, thereby ensuring the clamping effect of the clamping block 91.

[0055] Specifically, each clamping block 91 is provided at one end close to the patient's leg with a C-shaped elastic block for fixing the patient's leg.

[0056] The support airbag 92 is a retractable tubular structure, and is connected to the inflation pipeline 93. The inflation pipeline 93 has a retractable tube connected to each end thereof, and the end of each retractable tube away from the suspension mechanism 3 is connected to the side of the corresponding clamping block 91. In this way, when the patient's legs are placed in the suspension mechanism 3, the patient's legs press the support airbag 92 downward, making the internal space of the support airbag 92 smaller, forming an airflow, which passes through the inflation pipe 93 and enters the telescopic tube at the end of the inflation pipe 93. The airflow pushes the two clamping blocks 91 to move toward the side close to the patient's legs, and then the C-shaped elastic blocks on each elastic clamping block 91 are clamped on both sides of the patient's leg plaster. Two sets of fixing bolts 94 are symmetrically arranged on the two outer sides of the suspension mechanism 3, and each fixing bolt is connected to the outer side of the suspension mechanism 3 via a stopper. Each set of fixing bolts 94 has two fixing bolts 94, and each fixing bolt 94 in the same set is plugged into a corresponding guide rod 95 to fix the position of the clamping block 91 connected to the guide rod 95.

[0057] In actual application, a through hole communicating with the outside world is provided on the support airbag 92. After the patient's lower limb is removed, the support airbag 92 is no longer squeezed. At this time, the support airbag 92 gradually returns to its initial state.

[0058] The specific usage process is: Mr. Liu had a comminuted fracture of the middle part of his left femur. After being fixed with plaster, he needed to raise his lower limbs about 30 degrees to promote swelling reduction. Step 1: The medical staff clamps the mounting block 7 on the side of the bed board and fixes the mounting block 7 with fixing bolts; Step 2: The medical staff rotates the first rotating handle 8 to rotate the rotating tube 1 until the horizontal plate 2 rotatably connected to the rotating tube 1 is located above the patient's lower limb; Step 3: The medical staff rotates the second rotating handle 45 and the third rotating handle 62 in sequence, causing the H-shaped moving block 42 to move upward, thereby adjusting the rotation angle of the horizontal plate 2 on the vertical plane and the position of the suspension mechanism 3 on the horizontal plate 2, so that the suspension mechanism 3 is located directly above the lower limb and is at the target height; Step 4: Place the patient's lower limbs on the suspension mechanism 3; In this step, under the action of the weight of the patient's lower limb, the support airbag 92 is squeezed downward, thereby generating airflow. After the airflow passes through the inflation pipe 93 and the telescopic tube at the end of the inflation pipe 93, it pushes each clamping block 91 to move toward the side close to the patient's lower limb until the C-shaped elastic block of the clamping block 91 is stuck on the side of the patient's lower limb. Step 5: Remove the fixing bolt 94 and insert it into the limiting hole on the guide rod 95 to fix the position of the clamping block 91 to prevent the patient from moving around. Then support the airbag 92 to deflate and ensure the clamping effect of the clamping block 91. At this time, the suspension of the patient's lower limbs is completed.

[0059] After use, the fixing bolt 94 can be pulled out, and then the guide rod 95 can be pulled to pull the two clamping blocks 91 outward, and then the second rotating handle 45 can be rotated to lower the height of the suspension mechanism 3 until the patient's lower limbs are in a horizontal state, and then the patient's lower limbs can be removed from the suspension mechanism 3. Finally, the first rotating handle 8 can be rotated to make the cross plate 2 parallel to the bed so that the device can be stored.
