Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of broken bone docking auxiliary device, and particularly relates to a broken bone docking auxiliary device for limb docking. BACKGROUND

[0002] The broken bone docking auxiliary device is a key instrument for precise reduction and fixation of broken bones in orthopedic surgery. Its design combines mechanical mechanics and human engineering, and realizes multi-dimensional precise operation through adjustable structure. For example, some devices use bidirectional screw rod driving sliding blocks, cooperate with support rods and fixed plates to realize flexible adjustment of the operating table; the intramedullary cavity alignment device adapts to different diameters of bone marrow cavities through a rotatable intramedullary plug and a spring clamp structure, and ensures the precise alignment of the broken bone. Such devices not only can effectively fix the affected limb and reduce intraoperative displacement, but also can assist doctors to complete complex reduction operation, significantly improve the operation efficiency and healing quality, and are indispensable auxiliary tools in modern orthopedic treatment.

[0003] The patent document with publication number CN110680518A discloses a broken bone docking auxiliary device for orthopedics. Therefore, the technical problem of the present application is to provide a broken bone docking auxiliary device for orthopedics which can fix the broken bone of the patient and reduce the burden of medical staff. The technical solution is a broken bone docking auxiliary device for orthopedics, which comprises a first inverted U-shaped plate, a second inverted U-shaped plate, a first T-shaped sliding rail, a second T-shaped sliding rail, a first clamping plate, a first L-shaped guide rod and the like. The second inverted U-shaped plate is located in front of the first inverted U-shaped plate. The broken bone docking auxiliary device can be easily adjusted according to the fracture site of the patient, can fix the broken bone of the patient, can reduce the burden of medical staff, and can reduce the occupation of manual work, which is conducive to the performance of bone setting work.

[0004] The broken bone docking auxiliary device in the above patent document fixes the limb by driving the third clamping plate and the fourth clamping plate through the third L-shaped guide rod and the fourth L-shaped guide rod. Although the above device can fix the patient's limb, it can only be used when the patient is lying down, which makes it impossible for the patient to selectively adjust the comfortable angle after treatment. Therefore, a broken bone docking auxiliary device for limb docking is proposed. SUMMARY

[0005] In view of the above problems, a broken bone docking auxiliary device for limb docking is provided, which is hinged to the top end of the first stand, so that the placement rack can be flipped around the hinge with the first stand. Thus, the placement rack can meet the patient's limb flat or curled up posture. The patient can be in a comfortable state for treatment. The problem that the patient's limb can only be placed flat when using the broken bone docking auxiliary device is solved.

[0006] To address the problems of existing technologies, the present invention provides an auxiliary device for limb reattachment, comprising a medical bed, a fixed seat disposed on the medical bed, a suspension disposed on the fixed seat, a support mechanism disposed on the top of the suspension, a telescopic adjustment mechanism disposed on the top of the suspension, and a lifting mechanism disposed at the output end of the telescopic adjustment mechanism. The suspension is fitted with two sets of mounting seats for mounting the support mechanism and the telescopic adjustment mechanism. The support mechanism includes a first column that is longitudinally inserted into the mounting base, and a placement frame is hinged to the top of the first column. The placement frame has an L-shaped structure and a groove is provided inside the placement frame. The placement rack has symmetrical side plates fixed on both sides, and a clamping plate for holding the limb is provided on one side of the side plate.

[0007] As one technical solution of the present invention, a threaded tube is provided on the side plate; A lead screw is rotatably mounted on one side of the clamping plate. The lead screw is installed inside a threaded tube and can move along its central axis. A nut is rotatably mounted on one end of the threaded tube, and the internal thread of the nut is threadedly engaged with the external thread of the lead screw.

[0008] As one technical solution of the present invention, the side plate is symmetrically mined with first limiting holes; A first limiting slide bar is symmetrically fixed on one side of the clamping plate near the lead screw, and the first limiting slide bar can move along the central axis of the first limiting hole.

[0009] As one technical solution of the present invention, the telescopic adjustment mechanism includes a second column that is longitudinally installed in another set of mounting seats; The telescopic adjustment mechanism includes a sleeve, with an installation shaft fixed on one side of the sleeve. The installation shaft is rotatably mounted on the top of the second column. An internally threaded sleeve is rotatably mounted inside the sleeve, and a threaded rod is installed inside the internally threaded sleeve. The internal threads of the threaded rod and the internally threaded sleeve are engaged.

[0010] As one technical solution of the present invention, a handwheel is fixed to the outer end of the internal threaded sleeve.

[0011] As a technical solution of the present invention, an installation bracket is fixed to the outside of one end of the sleeve, and the anti-detachment component is used to prevent the lifting bracket from falling out of the second limiting hole. The support frame is equipped with straps for securing the feet.

[0012] The lifting mechanism includes a lifting frame fixed to one end of the threaded rod, and a second limiting slide rod that can move along the central axis of the second limiting hole is horizontally fixed on one side of the lifting frame.

[0013] As one technical solution of the present invention, an anti-detachment component is fixed at the end of the second limiting slide rod away from the lifting frame. The anti-detachment component is used to prevent the lifting frame from falling out of the second limiting hole.

[0014] As one technical solution of the present invention, the suspension includes a cantilever tube hinged to a fixed seat, and a retractable rod that can move along its central axis is installed inside the cantilever tube. One end of the retractable rod is provided with a support assembly, which includes a plumb rod fixed to the end of the retractable rod. A mounting sleeve is fitted at the bottom of the plumb rod, and a support foot is installed at the bottom end of the mounting sleeve.

[0015] As one technical solution of the present invention, a rotatable fastener is installed on one side of the top of the mounting sleeve, and the fastener is used to fix the height of the mounting sleeve.

[0016] As one technical solution of the present invention, the fixing seat is fixed to one side of the medical bed by bolts.

[0017] The advantages of this invention compared to the prior art are: 1. This application hinges the placement frame to the top of the first column, allowing the frame to rotate around the hinge point. This enables the placement frame to accommodate either a flat or curled-up position for the patient's limb, allowing for comfortable treatment. It solves the problem that traditional bone fracture repair devices only allow the patient's limb to be placed flat during use.

[0018] 2. This application involves installing an internally threaded sleeve inside a sleeve, and then installing a threaded rod inside the internally threaded sleeve. When the internally threaded sleeve is rotated, it drives the threaded rod, which in turn moves the lifting mechanism, thereby adjusting the distance between the lifting mechanism and the limb. This allows the lifting mechanism to meet the treatment needs of different patients.

[0019] 3. This application fixes a second limiting slide rod to one side of the lifting frame, and then installs the second limiting slide rod in a second limiting hole. When the lifting frame moves, the lifting frame will drive the second limiting slide rod to move along the second limiting hole, using the cooperation between the second limiting hole and the second limiting slide rod to limit the lifting frame. This effectively ensures the stability of the lifting frame. Attached Figure Description

[0031] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0032] See Figures 1-10As shown, a bone-jointing auxiliary device for limb docking includes a medical bed 1, a fixed seat 2 disposed on the medical bed 1, a suspension 3 disposed on the fixed seat 2, a support mechanism 6 disposed on the top of the suspension 3, a telescopic adjustment mechanism 8 disposed on the top of the suspension 3, and a lifting mechanism 9 disposed at the output end of the telescopic adjustment mechanism 8. Two sets of mounting seats 34 for mounting the support mechanism 6 and the telescopic adjustment mechanism 8 are sleeved on the suspension 3. The support mechanism 6 includes a first column 5 that is longitudinally inserted into the mounting base 34. The top of the first column 5 is hinged to a placement frame 61, which has an L-shaped structure and a groove 611 is provided inside the placement frame 61. Side plates 621 are symmetrically fixed on both sides of the placement frame 61, and a clamping plate 63 for clamping the limb is provided on one side of the side plate 621.

[0033] During treatment, the limb is placed in the groove 611, which supports the limb. The clamping plate 63 then secures the limb from both sides. The foot is fixed to the lifting mechanism 9, which in turn secures the foot, ensuring the limb is in a horizontal position. The placement frame 61 is hinged to the top of the first column 5, allowing it to rotate around the hinge point. This allows the placement frame 61 to accommodate either a flat or curled-up limb position, ensuring the patient's comfort during treatment. This solves the problem that traditional bone fracture repair devices only allow for a flat limb position.

[0034] See Figure 5 , Figure 6 and Figure 7 As shown, a threaded tube 622 is provided on the side plate 621; A lead screw 631 is rotatably mounted on one side of the clamping plate 63. The lead screw 631 is installed inside the threaded tube 622 and can move along its central axis. A nut 633 is rotatably mounted on one end of the threaded tube 622. The internal thread of the nut 633 is threadedly engaged with the external thread of the lead screw 631.

[0035] To ensure effective movement of the clamping plate 63, a nut 633 is installed at one end of the threaded tube 622. When the nut 633 rotates, it drives the threaded screw 631 to move horizontally, thereby causing the screw 631 to move the clamping plate 63 closer to or away from the limb. This allows the clamping plate 63 to fix or release the limb.

[0036] See Figure 5 , Figure 6 and Figure 7 As shown, the side plate 621 has symmetrically mined first limiting holes 623; A first limiting slide bar 632 is symmetrically fixed on one side of the clamping plate 63 near the lead screw 631. The first limiting slide bar 632 can move along the central axis of the first limiting hole 623.

[0037] To ensure the stability of the clamping plate 63, two first limiting slide rods 632 are symmetrically fixed on one side of the clamping plate 63. When the clamping plate 63 moves, the clamping plate 63 will drive the first limiting slide rods 632 to slide along the first limiting hole 623, thereby making the first limiting slide rods 632 cooperate with the first limiting hole 623 to fix the clamping plate 63.

[0038] See Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, the telescopic adjustment mechanism 8 includes a second column 7 that is longitudinally installed within another set of mounting bases 34; The telescopic adjustment mechanism 8 includes a sleeve 81, with a mounting shaft 811 fixed on one side of the sleeve 81. The mounting shaft 811 is rotatably mounted on the top of the second column 7. An internal threaded sleeve 84 is rotatably mounted inside the sleeve 81, and a threaded rod 83 is mounted inside the internal threaded sleeve 84. The internal threads of the threaded rod 83 and the internal threaded sleeve 84 are engaged.

[0039] An internal threaded sleeve 84 is installed inside a sleeve 81, and then a threaded rod 83 is installed inside the internal threaded sleeve 84. When the internal threaded sleeve 84 is rotated, it drives the threaded rod 83, which in turn moves the lifting mechanism 9, thereby adjusting the distance between the lifting mechanism 9 and the limb. This allows the lifting mechanism 9 to meet the treatment needs of different patients.

[0040] See Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, a handwheel 85 is fixed to the outer end of the internal threaded sleeve 84.

[0041] To enable effective rotation of the internal threaded sleeve 84, a handwheel 85 is fixed to one end of the internal threaded sleeve 84. When the internal threaded sleeve 84 needs to rotate, the handwheel 85 is turned so that it can drive the internal threaded sleeve 84 to rotate.

[0042] See Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, a mounting bracket 82 is fixed to the outside of one end of the sleeve 81, and a second limiting hole 821 is provided on the mounting bracket 82; The lifting mechanism 9 includes a lifting frame 91 fixed to one end of the threaded rod 83. A second limiting slide rod 92, which can move along the central axis of the second limiting hole 821, is horizontally fixed on one side of the lifting frame 91.

[0043] To ensure the stability of the lifting frame 91, a second limiting slide rod 92 is fixed to one side of the lifting frame 91, and then the second limiting slide rod 92 is installed in the second limiting hole 821. When the lifting frame 91 moves, the lifting frame 91 will drive the second limiting slide rod 92 to move along the second limiting hole 821. The second limiting hole 821 and the second limiting slide rod 92 cooperate to limit the lifting frame 91, effectively ensuring the stability of the lifting frame 91.

[0044] See Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, an anti-detachment component 93 is fixed at the end of the second limiting slide bar 92 away from the lifting frame 91. The anti-detachment component 93 is used to prevent the lifting frame 91 from falling out of the second limiting hole 821. The support frame 91 is equipped with straps 94 for securing the feet.

[0045] To prevent the second limiting slide rod 92 from falling out of the second limiting hole 821, an anti-detachment component 93 is fixed to one end of the second limiting slide rod 92. When the second limiting slide rod 92 moves along the second limiting hole 821, it will approach the mounting bracket 82. The mounting bracket 82 and the anti-detachment component 93 work together to limit the stroke of the second limiting slide rod 92, effectively preventing it from falling out of the second limiting hole 821.

[0046] By securing the strap 94 to the support frame 91, the support frame 91 can fix the feet, thereby ensuring a stable connection between the feet and the support frame 91.

[0047] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the suspension 3 includes a cantilever tube 31 hinged to the fixed seat 2, and a retractable rod 32 that can move along its central axis is installed inside the cantilever tube 31. One end of the retractable rod 32 is provided with a support component 4. The support component 4 includes a vertical rod 41 fixed to the end of the retractable rod 32. The bottom of the vertical rod 41 is fitted with an installation sleeve 42, and the bottom end of the installation sleeve 42 is fitted with a support foot 43.

[0048] By fixing the top of the plumb line 41 to the end of the retractable rod 32, and then installing a mounting sleeve 42 at the bottom of the plumb line 41, and a support foot 43 at the bottom of the mounting sleeve 42, the plumb line 41, mounting sleeve 42, and support foot 43 work together to support the retractable rod 32. This effectively prevents the retractable rod 32 from being suspended in the air, which would result in poor load-bearing capacity. Simultaneously, the support foot 43's contact with the ground effectively prevents lateral displacement of the suspension 3, thus ensuring the stability of the suspension 3.

[0049] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a rotatable fastener 44 is installed on one side of the top of the mounting sleeve 42, which is used to fix the height of the mounting sleeve 42.

[0050] By installing a fastener 44 on one side of the top of the mounting sleeve 42, when the fastener 44 is rotated, one end of the fastener 44 will come into close contact with the plumb rod 41 inside the mounting sleeve 42. This allows the fastener 44 to fix the mounting sleeve 42 and the plumb rod 41, thus ensuring stability between the plumb rod 41 and the mounting sleeve 42.

[0051] See Figure 1 As shown, the mounting base 2 is fixed to one side of the medical bed 1 by bolts.

[0052] To ensure stability between the mounting base 2 and the medical bed 1, the mounting base 2 is fixed to the medical bed 1 with bolts, so that the medical bed 1 and the mounting base 2 can be effectively connected.

[0053] Working principle: The patient lies flat on the medical bed 1, and then places their limb inside the groove 611 of the placement frame 61. By rotating the nut 633, the nut 633 drives the lead screw 631 to move horizontally along the threaded tube 622. At this time, the lead screw 631 drives the clamping plate 63 to fix the limb. When the patient's limb curls up, by rotating the placement frame 61, the patient's wrist is placed in the groove 611, allowing for adjustment to a comfortable position. Then, by rotating the handwheel 85, the handwheel 85 drives the internal threaded sleeve 84 to rotate. The rotation of the internal threaded sleeve 84 drives the threaded rod 83 to move. The movement of the threaded rod 83 drives the support frame 91 to contact the patient's foot, and then the patient's foot is fixed to the support frame 91 by the strap 94. A second limiting slide rod 92 is fixed to one side of the support frame 91 and then installed in the second limiting hole 821. When the lifting frame 91 moves, it drives the second limiting slide rod 92 to move along the second limiting hole 821. The second limiting hole 821 and the second limiting slide rod 92 cooperate to limit the lifting frame 91, effectively ensuring the stability of the lifting frame 91.

[0054] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
