Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a lower limb fracture fixation bracket. Background Technology

[0002] A fracture is a complete or partial break in the continuity of bone structure. In fracture treatment, reduction, fixation, and healing are three key steps, with fixation being a crucial link between reduction and healing. Good fixation not only consolidates the reduction but also promotes the speed and quality of fracture healing. Fixation and positioning devices play a role in immobilization and pain relief during fracture treatment.

[0003] In practical applications, patients usually need to use fixation braces to support and fix fractured legs. During this process, the tilt angle of the fixation components needs to be adjusted to meet the needs of leg tilt adjustment. However, the common tilt adjustment method is to rotate the fixation components and then lock them with bolts. This adjustment method is not convenient in actual operation, especially when multiple adjustments are required, and it is inefficient and cannot achieve quick and convenient support adaptation of the leg tilt angle.

[0004] Therefore, in order to improve the ease of operation of tilt angle adjustment, we propose a lower limb fracture fixation brace. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to quickly and conveniently adapt support to the leg tilt angle, and to propose a lower limb fracture fixation brace.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a lower limb fracture fixation brace, including: The fixing mechanism and the upright installed on the fixing mechanism; A crossbar is slidably connected to the outside of the upright, and a swivel ring is sleeved on the outside of the crossbar; The upper end of the swivel is fixedly connected to a sleeve, and a snap-fit ​​assembly is provided inside the sleeve. The snap-fit ​​assembly is used to lock the circumferential position of the sleeve, and a binding assembly is also fixedly installed at the upper end of the snap-fit ​​assembly.

[0007] Furthermore, the fixing mechanism includes a U-shaped frame; Both ends of the bottom of the U-shaped frame are formed with upper clamping plates, and both ends of the U-shaped frame are provided with through slots. The through slots are connected to mounting positions. A screw extending to the bottom of the U-shaped frame is inserted into the through slot. A lower clamping plate is fixedly installed at the bottom of the screw. A nut sleeve is rotatably connected inside the mounting position. The nut sleeve and the screw are threaded together.

[0008] Furthermore, a flat portion is provided on the outer side of the screw along the axial direction, and the screw is circumferentially locked by the flat portion and the U-shaped frame.

[0009] Furthermore, the upright and the U-shaped frame are movably connected and locked by a locking device, and the upper ends of the horizontal bar and the upright are movably connected and locked by a locking device.

[0010] Furthermore, the snap-fit ​​assembly includes a T-shaped post, a snap-fit ​​rod is fixedly installed at the bottom end of the T-shaped post, the outer side of the crossbar has a ring tooth portion, and the end of the snap-fit ​​rod passes through the sleeve and the swivel and snaps into the tooth groove of the ring tooth portion.

[0011] Furthermore, a spring is fixedly connected between the T-shaped post and the sleeve, a positioning glass bead is embedded on the outside of the T-shaped post, and a slot is provided on the outside of the sleeve for the sliding of the telescopic end of the positioning glass bead. A return torsion spring is provided between the sleeve and the crossbar.

[0012] Furthermore, the binding assembly includes a support plate and a strap fixed to one side of the support plate, the other end of which is fixed to the other side of the support plate via a connecting component.

[0013] Furthermore, a connecting plate is fixedly installed on the top of the T-shaped column, and two locking holes are opened on the end face of the connecting plate. Two sets of locking claws are fixedly installed on the bottom of the support plate, and each set of locking claws is engaged in the locking hole.

[0014] The present invention provides a lower limb fracture fixation bracket with the following advantages: The bracket uses a snap-fit ​​assembly to position the sleeve circumferentially, simultaneously adjusting the angle of the binding assembly. The leg is placed on the support plate and secured with straps. As the thigh is placed, the weight of the leg causes the entire T-shaped column to move downwards, and the locking tooth at the bottom of the T-shaped column engages with the toothed groove of the ring tooth on the outside of the crossbar. This achieves angle locking and fixation of the support plate. The operation is simple and convenient. Compared to the traditional bolt locking method, this angle adjustment method allows for quick and easy adjustment. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-4 As one embodiment of the present utility model, a lower limb fracture fixation bracket is disclosed, specifically the fixation bracket includes a fixation mechanism 1 and a vertical rod 2 installed on the fixation mechanism 1; A crossbar 3 is slidably connected to the outside of the upright 2, and a swivel ring 4 is sleeved on the outside of the crossbar 3; The upper end of the rotating ring 4 is fixedly connected to a sleeve 5, and a snap-fit ​​component 6 is provided inside the sleeve 5. The snap-fit ​​component 6 is used to lock the circumferential position of the sleeve 5, and a binding component 7 is also fixedly installed at the upper end of the snap-fit ​​component 6.

[0019] In some embodiments, the fixing mechanism 1 includes a U-shaped frame 11; Upper clamping plates 12 are formed at both ends of the bottom of the U-shaped frame 11. Through slots are opened at both ends of the U-shaped frame 11, and mounting positions are connected in the through slots. A screw 13 extending to the bottom of the U-shaped frame 11 is inserted into the through slot. A lower clamping plate 14 is fixedly installed at the bottom of the screw 13. A nut sleeve 15 is rotatably connected inside the mounting position. The nut sleeve 15 and the screw 13 are threadedly connected.

[0020] Specifically, in this embodiment, the upper clamping plate 12 and the lower clamping plate 14 are arranged opposite each other to form a U-shaped opening. In use, the upper clamping plate 12 and the lower clamping plate 14 are first clamped on the upper and lower sides of the bed edge. At this time, the screw 13 is driven to move upward by rotating the nut sleeve 15, so that the lower clamping plate 14 and the upper clamping plate 12 are clamped together until the lower clamping plate 14 and the upper clamping plate 12 are completely clamped on both sides of the bed edge, thus completing the fixation of the entire device.

[0021] Furthermore, to prevent the screw 13 from rotating circumferentially and to maintain smooth linear movement, a flat portion 16 is provided axially on the outer side of the screw 13 in this embodiment. The screw 13 is circumferentially locked by the flat portion 16 and the U-shaped frame 11. That is, in this embodiment, the through hole of the U-shaped frame 11 that adapts to the screw 13 is set as an oblong hole. The flat surface of the oblong hole is used to fit against the flat portion 16 to lock the circumferential position of the screw 13. When the nut sleeve 15 rotates, the circumferential position of the screw 13 is limited, thereby achieving the effect of vertical linear movement.

[0022] Specifically, in this embodiment, the upright 2 and the U-shaped frame 11 are movably connected and locked by the locking member 8. Of course, in this embodiment, the upright 2 and the U-shaped frame 11 can also be circumferentially locked by the cooperation of the above-mentioned flat part and waist-shaped hole. The crossbar 3 and the upper end of the upright 2 are movably connected and locked by the locking member 8. Specifically, the top of the upright 2 has a sleeve part, which is used to pass through the crossbar 3. The locking member 8 is set on the sleeve part. In addition, the horizontal bar 3 and the vertical bar 2 can also be circumferentially locked by the cooperation of the flat part and the waist-shaped hole to prevent circumferential rotation. Preferably, the locking part 8 in this embodiment is a bolt. The bolt tightening locking method is a conventional method for those skilled in the art, and will not be described in detail here.

[0023] In some embodiments, the snap-fit ​​assembly 6 of this invention includes a T-shaped post 61, and a snap-fit ​​rod 62 is fixedly installed at the bottom end of the T-shaped post 61. The snap-fit ​​rod 62 includes a rod segment fixed at the bottom of the T-shaped post 61 and a snap-fit ​​part fixed at the lower side of the rod segment. The outer side of the crossbar 3 has a ring tooth part 31. The end of the snap-fit ​​rod 62 passes through the sleeve 5 and the rotating ring 4 and is snapped into the tooth groove of the ring tooth part 31. That is to say, the sleeve 5 and the rotating ring 4 of this invention are connected. When the bottom of the snap-fit ​​rod 62 is snapped into the tooth groove of the ring tooth part 31, the circumferential position of the entire snap-fit ​​assembly 6 and the sleeve 5 can be locked to achieve the purpose of adjusting the tilt angle of the binding assembly 7.

[0024] It should be noted that in this embodiment, a spring 63 is fixedly connected between the T-shaped post 61 and the sleeve 5. A positioning glass bead 64 is embedded on the outside of the T-shaped post 61. A slot 65 is provided on the outside of the sleeve 5 for the sliding of the telescopic end of the positioning glass bead 64. The positioning glass bead 64 and the slot 65 are provided to guide the sliding of the T-shaped post 61. In actual use, the telescopic end of the positioning glass bead 64 can be pressed to make it retract inward, so as to achieve the purpose of disassembling the entire T-shaped post 61 and to optimize the ease of assembly. In order to reset the sleeve 5, a reset torsion spring 32 is provided between the sleeve 5 and the crossbar 3 in this embodiment.

[0025] In some embodiments, the binding assembly 7 of this utility model includes a support plate 71 and a binding strap 72 fixed to one side of the support plate 71. The other end of the binding strap 72 is fixed to the other side of the support plate 71 by a connecting component. Optionally, the connecting component in this embodiment can be a Velcro assembly. A hook surface can be provided on the end face of the binding strap 72, and a rough surface can be provided on the side of the support plate 71. In this way, by means of the adhesion of the hook surface and the rough surface, when the user's leg is placed on the support plate 71, the leg can be bound and fixed by the loop binding strap 72, thereby achieving the purpose of supporting and fixing the leg.

[0026] Furthermore, considering that different users have different leg circumferences, such as adults and children, it is difficult for a single support plate 71 to achieve the desired curvature. Therefore, in this embodiment, the support plate 71 is designed with a detachable structure, and support plates 71 with various curvatures can be designed and replaced according to actual needs. Specifically, a connecting plate 66 is fixedly installed on the top of the T-shaped column 61, and two locking holes 67 are opened on the end face of the connecting plate 66. Two sets of locking claws 73 are fixedly installed on the bottom of the support plate 71, and each set of locking claws 73 is engaged in the locking hole 67.

[0027] Specifically, in this embodiment, each set of two claws 73 are symmetrically spaced apart. The claws 73 are L-shaped and made of plastic. When disassembling, simply press the two claws 73 to deform them until they detach from the edge of the card hole 67 to separate and replace the support plate 71.

[0028] When in use, first fix the entire bracket to the side of the bed using the fixing mechanism 1, then adjust the height of the upright 2 and the lateral position of the crossbar 3 as needed, and lock the upright 2 and crossbar 3 using two locking parts 8. Afterwards, lift the patient's fractured leg and rotate the entire locking assembly 6 to the desired angle so that the binding assembly 7 reaches the predetermined tilt angle. At this time, the leg can be placed on the support plate 71 and secured with the binding strap 72. Simultaneously, due to the weight of the leg after placement, the entire T-shaped column 61 will move downwards, and the locking rod 62 at the bottom of the T-shaped column 61 will engage in the tooth groove of the ring tooth part 31 outside the crossbar 3. In this way, the angle of the support plate 71 can be locked and fixed. The operation is simple and convenient. Compared with the traditional bolt locking method, this angle adjustment method can be adjusted quickly and conveniently.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
