Description

Technical Field

[0001] The invention belongs to the field of fracture reduction, in particular to a multifunctional adjustable limb fracture reduction and fixation device. Background Art

[0002] The limb fracture reduction and fixation device is mainly used to reduce and fix the fracture site of patients with limb fractures. This device can effectively maintain the correct position of the fracture ends, prevent dislocation or displacement, and thus promote the normal healing process of the bones.

[0003] In order to prevent patients with fractures from encountering accidents due to unnatural twisting of the body before or during surgery, it is necessary to restrain the patient's limbs to prevent the patient from suffering secondary injuries. However, the fracture reduction devices in the prior art are affected by the body shape of the patients in actual use. If the restraint structure in the fracture reduction and fixation device cannot be well adapted to the patient, the patient's comfort will be reduced, thereby affecting the patient's recovery mood. What is more serious is that in some cases, the blood circulation of the restrained limbs will be hindered, thereby reducing the patient's recovery speed.

[0004] In addition, most of the existing limb fracture reduction and fixation devices have fixed structures and cannot be flexibly adjusted according to the patient's fracture conditions of different parts and severities. In actual clinical applications, patients have large individual differences, and their limbs are different in thickness, length, and fracture location. The existing devices are difficult to meet these diverse needs. This one-size-fits-all design not only affects the patient's experience, but may also lead to poor fixation effects and even the risk of re-displacement of the fracture site after reduction. At the same time, the operation of the existing devices is relatively complex, and medical staff need to spend more time and energy to adjust and fix them during use, which reduces medical efficiency to a certain extent. Especially in emergency situations, it may delay the patient's treatment.

[0005] Therefore, those skilled in the art have proposed a multifunctional adjustable limb fracture reduction and fixation device to solve the problems raised in the background art. Summary of the Invention

Secondly, the constraint structure lacks personalized design, which can easily cause discomfort and anxiety to the patient, and may hinder blood circulation and affect the recovery speed. In addition, the device is complicated to operate, and medical staff need to spend a lot of time to adjust it, which reduces medical efficiency and may delay treatment in emergency situations.

[0036] Several limiting mechanisms 2 are provided on one side of the horizontal plate 608, and the limiting mechanism 2 includes an arc-shaped plate 201, one side of the arc-shaped plate 201 is fixedly connected to two rotating rods 207, one side of the force-bearing rod 606 is provided with a limiting groove 607 adapted to the rotating rod 207, one side of the arc-shaped plate 201 is provided with two mounting grooves 208, the inner cavity of the mounting groove 208 is provided with a support plate 206, the inner cavity of the support plate 206 is provided with a screw sleeve 202, and the inner cavity of the screw sleeve 202 is connected to the stud 203 through a threaded connection.

[0037] A fixing mechanism 10 is provided on both sides of the outer wall of one side of the support plate 206, and the fixing mechanism 10 includes an iron-absorbing block 1005. One side of the iron-absorbing block 1005 is magnetically connected to one side of the adjacent curved plate 201, and the other side of the iron-absorbing block 1005 is rotatably connected to a movable rod 1003 through an ear seat 1004. A base 1001 is provided at one end of the movable rod 1003. One side of the base 1001 is fixedly connected to one side of the adjacent support plate 206, and the other side of the base 1001 is fixedly connected to a sleeve 1002. One end of the movable rod 1003 is slidably connected to the inner cavity of the adjacent sleeve 1002.

[0038] Sliding grooves 204 are formed on both inner walls of the mounting groove 208 . A sliding block 205 is slidably connected to the inner cavity of the sliding groove 204 . One side of the sliding block 205 is fixedly connected to one side of the adjacent support plate 206 .

[0039] The two ends of the thick rod 604 are respectively connected to the inner wall of the adjacent base plate 1 through a rotating shaft, one end of the thin rod 601 is connected to the inner wall of the adjacent base plate 1 through a rotating shaft, and the other end of the thin rod 601 passes through the side wall of the adjacent base plate 1 through a shaft sleeve and extends to one side of the base plate 1. The small pulley 603 and the corresponding large pulley 605 are connected by a winding transmission belt, and the two tooth columns 602 are connected by meshing with teeth.

[0040] As can be seen from the above, when the personnel need to use the limb fracture reduction and fixation device to fix and support the patient's fracture site, the device is first placed on the patient's limb fracture site, and then the sliding sleeve 703 in the sliding locking mechanism 7 is driven to drive the two docking rods 704 to move backward and disengage from the inside of the socket 5. Under the limiting action of the slide rail 702, the sliding sleeve 703 can only move in the horizontal direction and cannot rotate around the thin rod 601. Then the operator drives the thin rod 601 to rotate through the grip 701. At this time, the small pulley 603 on the outer ring of the thin rod 601 drives the large pulley 60 through the transmission belt. 5 and the thick rod 604 rotate synchronously. During the rotation of the thick rod 604, the several force-bearing rods 606 on its outer ring rotate and displace along the through slot 3, so that the cross plate 608 and the bottom plate 1 reach a parallel state, completing the posture adjustment of the overall support structure; then the sliding sleeve 703 is pushed to reinsert the docking rod 704 into the adjacent docking hole 705, thereby locking the rotation angle of the thin rod 601; at the same time, since the tooth column 602 is engaged with the thin rod 601 on the other side and is linked to the large pulley 605 through the small pulley 603, the thick rod 604 on the other side also rotates synchronously, thereby The limiting mechanisms 2 on both sides are driven to be closed to fit the contour of the patient's limbs; next, the height position of the limiting mechanism 2 is adjusted adaptively, and the operator pulls the handle 806 on the maintaining mechanism 8 outward to drive the insertion rod 807 to disengage from the inner cavity of the socket 5 on the straight plate 802, and moves the long plate 803 upward or downward to drive the straight plate 802 and the curved plate 201 thereon to adjust the height position synchronously until the curved plate 201 reaches a suitable distance from the patient's limb fracture. Then, the handle 806 is released, and the reset spring 805 pushes the insertion rod 807 to re-insert the corresponding socket 5 through the baffle 804. Finally, adjust the angle of each stud 203 and the support point of the patient's fracture in turn, pull the movable rod 1003 upward to make it slide in the sleeve 1002, release the magnetic connection between the magnetic block 1005 and the curved plate 201, and then drive the support plate 206 to move by the displacement of the sliding block 205 in the sliding groove 204, thereby changing the angle of the stud 203, and then rotate the stud 203, and use the threaded fit between it and the screw sleeve 202 to further fine-tune its position so that it fits tightly with the patient's fracture, completing the installation and fixation process of the entire device;

[0041] By setting up an adjustable limiting mechanism 2, a maintaining mechanism 8, and a matching structure of the stud 203 and the screw sleeve 202, personalized adaptation to different body shapes, different fracture locations and severity levels is achieved, overcoming the problem that the traditional fixed structure is difficult to meet diverse clinical needs, and improving the applicability and fixation effect of the device; secondly, by setting up the sliding sleeve 703, the docking rod 704, the docking hole 705 in combination with the thin rod 601, the tooth column 602, the small pulley 603, the large pulley 605, the thick rod 604, and the force-bearing rod 606, the device can complete posture adjustment and locking in a short time, simplifying the operating process of medical staff and improving work efficiency, which is particularly suitable for for rapid processing in emergency situations; in addition, by maintaining the automatic locking structure of the return spring 805, the insertion rod 807 and the socket 5 in the mechanism 8, not only the stability of the height adjustment is improved, but also the patient's comfort is enhanced, avoiding blood circulation disorders caused by long-term compression; at the same time, through the magnetic connection structure of the magnetic block 1005 and the arc plate 201, the support component can be quickly disassembled and the angle can be flexibly adjusted, further improving the convenience and safety of use; overall, the device solves the shortcomings of existing limb fracture reduction and fixation devices in terms of adaptability, ease of operation, fixation stability and patient comfort through multi-level adjustment and modular design.

[0042] Embodiment 2: This embodiment is basically the same as the previous embodiment, with the difference that a locking mechanism 7 is provided on the outer ring of the extended end of one of the thin rods 601, and the locking mechanism 7 includes a handle 701, and one end of the handle 701 is fixedly connected to the extended end of the adjacent thin rod 601, and a sliding sleeve 703 is provided on the extended end of one of the thin rods 601, and the inner cavity of the sliding sleeve 703 is slidingly connected to the sliding rail 702, and one side of the sliding rail 702 is fixedly connected to the outer ring of the adjacent thin rod 601, and one end of the sliding sleeve 703 is fixedly connected to two docking rods 704, and two docking holes 705 are provided on one side of the base plate 1, and one end of the docking rod 704 is plugged into the corresponding docking hole 705.

[0043] One end of the force-bearing rod 606 passes through the adjacent through slot 3 and is fixedly connected to one side of the corresponding transverse plate 608. A maintaining mechanism 8 is provided on one side of the transverse plate 608. The maintaining mechanism 8 includes a structural box 801 and a long plate 803. One end of the rotating rod 207 passes through the inner cavity of the adjacent limiting slot 607 and is fixedly connected to one side of the corresponding long plate 803. One side of the structural box 801 is fixedly connected to one side of the transverse plate 608. One side of the long plate 803 is fixedly connected with a straight plate 802, and one end of the straight plate 802 passes through the side wall of the adjacent structural box 801 and extends to one side of the structural box 801. Several sockets 5 are provided on one side of the straight plate 802 and along the horizontal direction of the straight plate 802. The inner cavity of the structural box 801 is horizontally provided with an insertion rod 807, and one end of the insertion rod 807 passes through the side wall of the adjacent structural box 801 and is plugged into the corresponding socket 5.

[0044] As can be seen from the above, through the arrangement of the support plate 206, the fixing mechanism 10, the magnetic block 1005, the curved plate 201, the ear seat 1004, the movable rod 1003, the base 1001, and the sleeve 1002, when adjusting the angle of the stud 203, the operator pulls the movable rod 1003 upward to slide it in the sleeve 1002, thereby releasing the magnetic connection between the magnetic block 1005 and the curved plate 201, and then the displacement of the sliding block 205 in the sliding groove 204 drives the support plate 206 to move, thereby adjusting the angle of the stud 203, achieving the effect of facilitating quick disassembly and flexible adjustment of the position of the support assembly, and improving the convenience of use. The configuration of the mounting slot 208, the sliding slot 204, the sliding block 205, and the support plate 206 allows the sliding block 205 to slide along the inner cavity of the sliding slot 204 when the limit mechanism 2 is adjusted for lateral displacement, thereby driving the support plate 206 to move synchronously. This improves the adjustment flexibility of the support structure and ensures displacement stability, thus facilitating precise fitting of the patient's limb contours. Furthermore, the configuration of the thick rod 604, the base plate 1, the thin rod 601, the small pulley 603, the large pulley 605, and the tooth column 602 allows the thin rod 601 to rotate, and the small pulley 603 on its outer ring drives the large pulley 605 and the thick rod 604 to rotate via the transmission belt. At the same time, the gear column 602 engages to transmit the thin rod 601 on the other side to rotate synchronously, achieving the effect of linkage adjustment of the force-bearing rods 606 on both sides and unified control of the overall structural posture, thereby improving the operating efficiency and stability of the device. Through the arrangement of the thin rod 601, the handle 701, the sliding sleeve 703, the slide rail 702, the docking rod 704, and the docking hole 705, after the personnel drives the thin rod 601 to rotate through the handle 701, the sliding sleeve 703 disengages or inserts the docking rod 704 into the docking hole 705, thereby locking the rotation angle of the thin rod 601, achieving the effect of rapid positioning and firmly maintaining the parallel state of the horizontal plate 608 and the bottom plate 1, thereby improving the safety of operation. And reliability, through the arrangement of the force-bearing rod 606, the through slot 3, the horizontal plate 608, the maintaining mechanism 8, the structural box 801, the long plate 803, the straight plate 802, the socket 5, the insertion rod 807, the rotating rod 207, and the limiting slot 607, after completing the posture adjustment of the horizontal plate 608 and the bottom plate 1, pull the handle 806 to drive the insertion rod 807 to disengage from the socket 5, adjust the height of the long plate 803 to drive the straight plate 802 and the arc-shaped plate 201 thereon to move up and down, and after releasing it, the reset spring 805 pushes the insertion rod 807 to reinsert into the socket 5, thereby achieving the effect of quickly adjusting the height of the limiting mechanism 2 and stably locking it, thereby improving the adaptability of the device to patients of different body shapes.

[0045] Example 3: This example is basically the same as the previous example, except that the other end of the insertion rod 807 passes through the side wall of the adjacent structural box 801 and is fixedly connected to a pull handle 806, and the outer ring of the insertion rod 807 is sleeved with a blocking piece 804, and one end of the blocking piece 804 is against the inner wall of the adjacent structural box 801.

[0046] The outer ring of the insertion rod 807 is provided with a return spring 805, one end of the return spring 805 is fixedly connected to one end of the adjacent blocking piece 804, and the other end of the return spring 805 is fixedly connected to the inner wall of the adjacent structural box 801, and one end of the straight plate 802 is fixedly connected to the pointed plate 9.

[0047] Two adjacent arc-shaped plates 201 are fixedly connected via a plurality of connecting rods 4 .

[0048] The outer ring of the rotating rod 207 is adapted to the inner cavity of the corresponding limiting groove 607, and the outer ring of the force-bearing rod 606 is adapted to the inner cavity of the corresponding through groove 3.

[0049] As can be seen from the above, through the arrangement of the plug rod 807, the pull handle 806, and the baffle 804, during the adjustment process, the personnel can pull the pull handle 806 outward to drive the plug rod 807 out of the socket 5, which is easy to operate, and the baffle 804 is used to limit the retraction stroke of the plug rod 807, thereby achieving the effect of improving the controllability and convenience of the adjustment process. Through the arrangement of the plug rod 807, the return spring 805, the baffle 804, and the structural box 801, after the plug rod 807 is pulled out, the return spring 805 pushes the plug rod 807 to automatically reset and reinsert it into the corresponding socket 5 through the force of the baffle 804, thereby achieving automatic locking, improving adjustment stability and usability. The effect of convenience is that through the setting of two arc-shaped plates 201 and the connecting rod 4, a stable connection structure is formed between the multiple arc-shaped plates 201, which enhances the overall rigidity and support consistency of the limiting mechanism 2, and achieves the effect of preventing support failure due to local deformation and improving fixation reliability. Through the setting of the rotating rod 207, the limiting groove 607, the force-bearing rod 606, and the through groove 3, the rotating rod 207 slides and fits in the limiting groove 607, and the force-bearing rod 606 slides and fits in the through groove 3, ensuring that the paths of each component are accurate and without offset during movement, thereby achieving the effect of improving the operating accuracy and stability of the overall structure and avoiding the risk of dislocation.
