Description

Technical Field

[0001] The present invention relates to the field of medical supports, and more particularly to a traction bed assembly arm. Background Art

[0002] Hip fractures (intertrochanteric fractures, subtrochanteric fractures, and femoral neck fractures) and femoral shaft fractures are common lower limb fractures in clinical practice and usually require surgical treatment with closed reduction and intramedullary nailing. For elderly patients, closed reduction using a traction bed is required during surgery, with the affected limb suspended in the air. However, due to the effect of gravity, the distal end of the fracture often shifts downward.

[0003] The traditional reduction method is for the assistant to support the distal end of the fracture with both hands from below to correct the anterior-posterior displacement of the fracture end until the surgeon inserts the intramedullary nail. However, this reduction method increases the workload of medical staff during the operation, and long-term lifting makes it difficult to maintain accurate reduction by manpower. At the same time, it increases the risk of radiation exposure to medical staff during fluoroscopy.

[0004] In order to solve the above problems, medical staff usually use a leg lift (a straight rod with a base and a soft pad on the top, used to support the affected limb during disinfection) to support the distal end of the fracture and adjust the position of the leg lift under fluoroscopy. Although it can replace medical staff in lifting the affected limb to a certain extent, during use, the leg lift must be fixed before disinfection and draping. Since the leg lift is close to the operating area, it is difficult to disinfect the operating area and increase the risk of surgical infection. Once the leg lift is fixed, it cannot be adjusted during surgery, making it difficult to deal with secondary displacement of the fracture during surgery. There are still certain inconveniences in actual use. Summary of the Invention

[0040] like Figures 1 to 10 As shown, an embodiment of the present invention provides a traction bed combination arm, including a first fixed rod 10, a second fixed rod 11, a first bracket 13 and a second bracket 14, a rotating seat 17 is provided between the first fixed rod 10 and the second fixed rod 11, and a clamping assembly is provided on the lower side of the second fixed rod 11; the clamping assembly includes a movable rod 18 fixedly connected to the lower end of the second fixed rod 11, the outer surface of the movable rod 18 is slidably connected to a movable plate 20, the outer surface of the movable rod 18 is threadedly connected to a rotating cover 19, the outer surface of the movable plate 20 is fixedly connected to a first capsule 31, the outer surface of the movable plate 20 is provided with a receiving groove 33, the inner surface of the receiving groove 33 is fixedly connected to the second capsule 34, and a conduit 32 is embedded in the inner side of the movable plate 20, and the upper and lower ends of the conduit 32 are respectively connected to the interior of the first capsule 31 and the second capsule 34.

[0041] The number of the rotating cover 19 and the movable plate 20 are both two groups and are symmetrically distributed. The outer surface of the movable plate 20 is in rotational contact with the rotating cover 19. The movable plate 20 is an L-shaped structure. The outer surface of the first capsule 31 is fixedly connected to the contact plate 35. The first capsule 31 is located on the upper side of the second capsule 34.

[0042] The outer surface of the second capsule 34 is fixedly connected with a Velcro 36 , the outer surface of the movable plate 20 is fixedly connected with an extrusion plate 21 , the contact plate 35 is made of wear-resistant elastic material, the rotating seat 17 is annular, and the first fixing rod 10 is located directly above the second fixing rod 11 .

[0043] By adopting the above technical solution, when the combined arm is in use, it is necessary to fix the combined arm at an appropriate position on the surface of the traction rod. The first fixed rod 10, the second fixed rod 11, the first bracket 13, and the second bracket 14 are the main supporting structures of the combined arm. The second fixed rod 11 rotatably supports the first fixed rod 10 through the rotating seat 17, so that the first fixed rod 10 can rotate a certain angle, thereby adjusting the working angle of the combined arm according to the patient's body position. During operation, the two sets of movable plates 20 are placed on the outside of the traction rod, and then the user simultaneously rotates the two sets of rotating covers 19. The rotating covers 19 are threadedly connected to the movable rod 18. During the rotation process, they move along the axis of the movable rod 18. During the movement, the rotating covers 19 drive the two sets of movable plates 20 to move toward each other. The movable plates 20 drive the extrusion plates 21 to fit the surface of the traction rod. By clamping and fixing the two sets of movable plates 20 to the traction rod, the extrusion plates 21 can effectively increase the friction between the movable plates 20 and the traction rod, thereby making the movable plates 20 clamped more tightly with the traction rod, which helps to improve the stability of the combined arm during use.

[0044] The movable plate 20 will drive the first sac 31 to move synchronously during the movement. The outer surface of the first sac 31 protrudes from the outer side of the movable plate 20. After the movable plate 20 moves a certain distance, the contact plate 35 on the outer surface of the first sac 31 will first contact the outer surface of the traction rod. As the movable plate 20 continues to move, the movable plate 20 will cooperate with the traction rod to squeeze the first sac 31. At this time, the gas inside the first sac 31 will enter the second sac 34 through the conduit 32. The second sac 34 will be inflated and drive the Velcro 36 to move synchronously. The movable plate 20 fixes and supports the second sac 34 through the storage groove 33. As the second sac 34 gradually expands, the two groups of second The capsules 34 will respectively drive the Velcro 36 to fit and contact, so that the two groups of Velcro 36 are bonded together. The two groups of second capsules 34 extend from the inside of the storage groove 33 and cover the lower side of the traction rod, which can not only clamp the traction rod in different directions, but also further increase the extrusion force between the movable plate 20 and the traction rod, so that the combination arm can be clamped more firmly, and the probability of accidental sliding of the combination arm on the surface of the traction rod can be effectively reduced, thereby improving the safety and reliability of the combination arm during use. At the same time, the clamping assembly can clamp the combination arm on the surface of traction rods with different diameters, thereby increasing the application range of the combination arm to a certain extent.

[0045] like Figure 6 and Figure 9As shown, an adjustment component is provided on the upper side of the first fixed rod 10, and the adjustment component includes a first pin shaft 12 connected to the first fixed rod 10 for damped rotation, the front and rear sides of the outer surface of the first pin shaft 12 are fixedly connected to the second bracket 14, the first bracket 13 is connected to the second pin shaft for damped rotation away from one end of the first fixed rod 10, and the outer surface of the second pin shaft is fixedly connected to the second bracket 14.

[0046] The outer surfaces of the first pin shaft 12 and the second pin shaft are both provided with positioning grooves 37, and the positioning grooves 37 are in several groups and distributed in a ring array. The left side of the outer surface of the first bracket 13 is threadedly connected with a push rod 38, and the push rod 38 passes through the interior of the positioning groove 37 and engages with the positioning groove 37.

[0047] By adopting the above technical solution, the angles of the first bracket 13 and the second bracket 14 are adjusted according to the position of the patient's limbs. For this purpose, an adjustment component is provided. When the adjustment component is working, the operator rotates the push rod 38 clockwise. At this time, the tip of the push rod 38 will be out of contact with the positioning groove 37 on the surface of the first pin shaft 12 and the second pin shaft. Then, the operator rotates the first bracket 13 with the first pin shaft 12 as the fulcrum as needed, and rotates the second bracket 14 with the second pin shaft as the fulcrum. The first pin shaft 12 and the second pin shaft are respectively connected to the first fixing rod 10 and the first bracket 13 with damping rotation. When there is no external force, the angle of the first bracket 13 will remain stable. When the first bracket 13 and the second bracket 14 are in a state of being rotated, the angle of the first bracket 13 will remain stable. After the frame 14 rotates to a certain angle, the operator rotates the push rod 38 counterclockwise so that the tip of the push rod 38 is again engaged with the positioning groove 37. The push rod 38 cooperates with the positioning groove 37 to lock and fix the first bracket 13 and the second bracket 14, so that the first bracket 13 and the second bracket 14 can remain stable during the use of the combined arm, and at the same time, the probability of accidental deflection of the first bracket 13 and the second bracket 14 can be effectively reduced. While ensuring the operational flexibility of the combined arm, it can also effectively improve the reliability of the combined arm. When performing fracture surgery on a patient, the adjustment component can fine-tune the position and angle of the affected limb, which not only helps to improve the surgical accuracy of the patient's fracture site.

[0048] like Figure 4 、 Figure 6 and Figure 7 As shown, a limiting assembly is provided on the upper side of the second bracket 14, and the limiting assembly includes a rotating shaft 28 rotatably connected to the second bracket 14, and the outer surface of the rotating shaft 28 is rotatably connected to the mounting seat 15. The number of the mounting seats 15 is two groups and they are symmetrically distributed on the front and rear sides of the second bracket 14. The outer surface of the upper end of the mounting seat 15 is fixedly connected to a bracket 16, and the bracket 16 is arc-shaped.

[0049] A clamping block 30 is fixedly connected to the outer surface of the rotating shaft 28. The clamping blocks 30 are arranged in several groups and are distributed in a ring array on the outer side of the rotating shaft 28. A clamping slot 29 is embedded on the inner side of the second bracket 14. The clamping slot 29 extends to the outer side of the mounting seat 15. The clamping slot 29 is engaged with the clamping block 30. A knob 39 is fixedly connected to the outer surface of the front end of the rotating shaft 28.

[0050] By adopting the above technical solution, the second bracket 14 rotatably supports the rotating shaft 28, and the mounting seat 15 is movably supported by the rotating shaft 28. The bracket 16 on the surface of the mounting seat 15 is used to lift the distal end of the patient's limb. The affected limb is lifted and supported by the bracket 16 during the operation. This can not only effectively reduce the workload of medical staff in manual lifting, thereby reducing the labor cost during the operation to a certain extent, but also the bracket 16 can fully expose the patient's wound for preoperative disinfection and effectively reduce the risk of occupational exposure of medical staff when performing C-arm fluoroscopy during the operation.

[0051] When the arm 16 is in the correct position, the operator rotates the shaft 28 in the opposite direction by rotating the knob 39. At this time, the shaft 28 drives the block 30 to move into the slot 29. The block 30 cooperates with the slot 29 to lock the shaft 28 and the mounting seat 15, so that the position of the bracket 16 remains stable. By setting a limit assembly to adjust the angle of the bracket 16, the operation needs during the operation can be met, thereby improving the functionality and flexibility of the combined arm during use.

[0052] like Figure 6 As shown, a traction assembly is provided between the first bracket 13 and the second bracket 14, and the traction assembly includes a cavity 22 opened inside the first bracket 13, the cavity 22 is a T-shaped structure and passes through the outside of the first bracket 13, a fixed shaft 23 is fixedly connected inside the cavity 22, and a traction bar 24 is fixedly connected to the outer surface of the right end of the second bracket 14.

[0053] A sliding rod 26 is slidably connected to the inside of the cavity 22, and the outer surface of the fixed shaft 23 is in sliding contact with the traction bar 24. The traction bar 24 is fixedly connected to the sliding rod 26 at one end away from the second bracket 14. The traction bar 24 is made of elastic material, and a positioning hole 27 is provided on the outer surface of the upper end of the first bracket 13.

[0054] A positioning rod 25 is engaged on the inner side of the positioning hole 27. The positioning rod 25 has a T-shaped structure. The lower end of the positioning hole 27 passes through the lower side of the sliding rod 26. The number of the positioning holes 27 is several groups and is distributed in a linear array. The first fixing rod 10, the second fixing rod 11, the first bracket 13 and the second bracket 14 are all made of polymer radiation-resistant material.

[0055] By adopting the above technical solution, when the angle of the second bracket 14 is adjusted, in order to further improve the stability of the second bracket 14, a traction assembly is provided, and the cavity 22 opened on the surface of the first bracket 13 can reduce the dead weight of the first bracket 13, thereby reducing the difficulty of carrying and clamping the combined arm to a certain extent. The first bracket 13 fixedly supports the fixed shaft 23 through the cavity 22, and the fixed shaft 23 can guide the traction bar 24. When the second bracket 14 swings with the second pin shaft as the fulcrum, the second bracket 14 will stretch the traction bar 24. At this time, the traction bar 24 can apply a certain pulling force to the second bracket 14. The traction bar 24 can improve the supporting performance of the second bracket 14 to a certain extent, thereby improving the carrying capacity of the combined arm to a certain extent.

[0056] The elastic force of the traction bar 24 can increase the resistance of the first bracket 13 during rotation to a certain extent, and the cavity 22 can support the sliding rod 26 slidingly, and the positioning rod 25 can cooperate with the positioning hole 27 to play a positioning and fixing role in positioning the slide bar 26, and the slide bar 26 is kept stable so that the traction bar 24 can remain taut, thereby keeping the tension of the traction bar 24 within an appropriate range. When the tension of the traction bar 24 needs to be increased, the operator first removes the positioning rod 25 from the positioning hole 27, and then moves the slide bar 26 along the inside of the cavity 22 toward the side of the second pin. As the slide bar 26 gradually moves, the traction bar 24 can be stretched. After the slide bar 26 moves to the appropriate position, the positioning rod 25 is inserted into the corresponding positioning hole 27 again, and the lower end of the positioning rod 25 passes through the surface of the slide bar 26. The positioning rod 25 cooperates with the positioning hole 27 to keep the slide bar 26 stable, thereby realizing flexible adjustment of the tension of the traction bar 24, thereby further improving the functionality of the combined arm.

[0057] like Figure 10 As shown, the bracket 16 is provided with a fixing assembly on its outer surface. The fixing assembly includes a movable groove 40 formed on the outer surface of the bracket 16. A core shaft 41 is fixedly connected to the inner surface of the movable groove 40. A clamping plate 42 is rotatably connected to the outer surface of the core shaft 41. A backing plate 43 is fixedly connected to the inner surface of the clamping plate 42. The movable grooves 40 and clamping plates 42 are provided in several groups and are symmetrically distributed. An elastic band 44 is fixedly connected between adjacent clamping plates 42. Both the clamping plates 42 and the backing plate 43 are arc-shaped.

[0058] By adopting the above technical solution, after the patient's limb is placed on the surface of the bracket 16, the lower end of the limb will contact the splint 42 and the pad 43 on the upper side of the bracket 16, and the bracket 16 supports the splint 42 through the core shaft 41, so that the splint 42 can rotate with the core shaft 41 as the fulcrum, and the splint 42 will flip under the action of the gravity of the patient's diseased limb, so that the upper half of the splint 42 is covered on the upper side of the patient's limb. The symmetrically distributed splints 42 can clamp and fix the patient's limb, thereby effectively reducing the chance of accidental deviation of the patient's limb during reduction surgery, and further improving the support stability of the patient's limb, which helps to improve the accuracy of the patient's surgical reduction. The pad 43 on the inner side of the splint 42 is located There is a certain buffering effect between the patient's limbs and the splint 42, which helps to reduce the risk of excessive clamping of the patient's limbs by the splint 42. At the same time, the pad 43 can increase the friction between the splint and the patient's limbs to a certain extent, thereby further improving the support stability of the patient's limbs. During the flipping process, the splint 42 will stretch the elastic belt 44, and the elastic belt 44 will contact the lower part of the patient's limbs, so that the elastic belt 44 can be wrapped around the lower side of the patient's limbs, playing a certain supporting and limiting role for the patient's limbs. After the surgical reduction is completed, when the patient's limbs are out of contact with the splint 42, the splint 42 will rotate in the opposite direction under the elastic force of the elastic belt 44, so that the splint 42 automatically completes the reduction operation.

[0059] The technical solution provided by the present invention has the following workflow:

[0060] When in use, the two sets of movable plates 20 are placed on the outside of the traction rod. The rotating cover 19 will drive the two sets of movable plates 20 to move toward each other during the movement. The movable plates 20 will drive the extrusion plates 21 to fit on the surface of the traction rod. The two sets of movable plates 20 are clamped and fixed to the traction rod. The movable plates 20 will cooperate with the traction rod to squeeze the first capsule 31. At this time, the gas inside the first capsule 31 will enter the second capsule 34 through the conduit 32. As the second capsule 34 gradually expands, the two sets of second capsules 34 will respectively drive the Velcro 36 to fit in contact, so that the two sets of Velcro 36 are bonded together, and the traction rod can be clamped in different directions. The first bracket 13 and the second bracket 14 can be locked and fixed by the top rod 38 cooperating with the positioning groove 37. In this way, the first bracket 13 and the second bracket 14 can remain stable during the use of the combined arm. The bracket 16 on the surface of the mounting seat 15 is used to support the distal end of the patient's limb. The affected limb is supported by the bracket 16 during the operation, which can effectively reduce the workload of medical staff in manual lifting. The rotating shaft 28 and the mounting seat 15 are locked and fixed by the block 30 and the slot 29, so that the position of the bracket 16 remains stable. When the second bracket 14 swings with the second pin shaft as the fulcrum, the second bracket 14 will stretch the traction bar 24. At this time, the traction bar 24 can apply a certain pulling force to the second bracket 14. The traction bar 24 can improve the supporting performance of the second bracket 14 to a certain extent, thereby improving the carrying capacity of the combined arm to a certain extent.
