[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] like Figure 1 and Figure 2 As shown, a hip fixation device includes a hip fixation component 1, a leg fixation component 2, and a side support component 3. The lower end of the leg fixation component 2 is connected to the lower end of the side support component 3, and the upper end of the side support component 3 is detachably connected to the left or right side of the hip fixation component 1, allowing the leg fixation component 2 to be switched between the left and right sides of the hip fixation component 1. During assembly, depending on which side of the patient's hip needs fixation (left or right), the upper end of the side support component 3 is selectively connected to the left or right side of the hip fixation component 1; then, the lower end of the leg fixation component 2 is fixed to the lower end of the side support component 3, completing the overall assembly.

[0024] This embodiment utilizes the detachable connection between the side support assembly 3 and the hip fixation assembly 1, allowing for flexible switching between installing the leg fixation assembly 2 on the left or right side of the hip fixation assembly 1. When the patient needs fixation of the left hip, the side support assembly 3 is connected to the left side of the hip fixation assembly 1; when the right side needs fixation, the connection is switched to the right side, without requiring replacement of the entire device. This achieves a universal design for both sides, eliminating the need for separate production of left and right fixators, reducing production costs and inventory pressure. Simultaneously, it simplifies clinical operation, allowing doctors to quickly switch according to patient needs, improving ease of use.

[0025] In some implementation schemes, see Figure 1 , Figure 3 and Figure 6The side support assembly 3 includes a first connecting mechanism 31 and a second connecting mechanism 32 connected vertically. The first connecting mechanism 31 has a through hole 301. The hip fixation assembly 1 adopts an openable support. By opening the openable support and inserting its left or right side into the through hole 301, the first connecting mechanism 31 and the side support assembly 3 are detachably connected to the hip fixation assembly 1. The leg fixation assembly 2 is connected to the second connecting mechanism 32. During assembly, first open the openable support of the hip fixation assembly 1. Depending on which side of the patient's hip needs to be fixed, insert the left or right side of the support into the through hole 301 of the first connecting mechanism 31. Then close the support to achieve a detachable connection between the side support assembly 3 and the hip fixation assembly 1. Finally, fix the leg fixation assembly 2 to the second connecting mechanism 32 to complete the overall assembly. The operation is convenient and shortens the assembly time.

[0026] In some implementation schemes, see Figures 4 to 8 The first connecting mechanism 31 includes a first base 311 and a first connector 312, and the second connecting mechanism 32 includes a second base 321 and a second connector 322. The first base 311 and the second base 321 are each provided with a slot 302, and a latch 303 is provided in the slot 302. The first connector 312 and the second connector 322 are each provided with a locking hole 304, and the latch 303 engages with the locking hole 304. Specifically, in the first connecting mechanism 31, the latch of the first base 311 engages with the locking hole of the first connector 312; in the second connecting mechanism 32, the latch of the second base 321 engages with the locking hole of the second connector 322. A through hole 301 is formed in the first base 311 for connection to the hip fixation component 1; the second base 321 is connected to the leg fixation component 2.

[0027] During assembly, the first connector 312 is inserted into the slot 302 of the first base 311, so that the latch 303 of the first base 311 engages with the locking hole 304 of the first connector 312, thus completing the assembly of the first connecting mechanism 31; the second connector 322 is inserted into the slot 302 of the second base 321, and the second connecting mechanism 32 is assembled by the latch 303 engaging with the locking hole 304; then the openable support of the hip fixation component 1 is opened, and the left or right side of the support is inserted into the through hole 301 in the first base 311, thus completing the connection between the first connecting mechanism 31 and the hip fixation component 1; finally, the leg fixation component 2 is connected and fixed to the second connecting mechanism 32, thus completing the overall assembly of the fixation device.

[0028] In one exemplary implementation, see Figures 5 to 8The first connector 312 and the second connector 322 each have multiple locking holes 304 distributed longitudinally. The latch 303 is an elastic element that can be detachably engaged with any of the locking holes 304. Specifically, the latch 303 includes a latch body and a spring piece. The latch body is fixed to one end of the spring piece, and the other end of the spring piece is fixedly connected to the base. The working principle is as follows: the multiple longitudinally distributed locking holes 304 provide multiple length adjustment positions. The elastic latch 303 achieves positioning by engaging with the locking hole 304 through elastic force. When adjustment is needed, according to the patient's height or limb length, the latch 303 is released by pressing it to disengage it from the current locking hole 304. Then, the first connector 312 or the second connector 322 is slid to adjust to the target position, and the latch 303 automatically springs into the corresponding locking hole 304 to complete the fixation. This achieves stepless length adjustment of the side support assembly 3, adapting to patients of different heights and limb lengths, improving versatility, and the adjustment operation is simple, allowing patients or doctors to quickly complete the adaptation.

[0029] In one exemplary implementation, see Figure 1 , Figure 2 , Figure 7 and Figure 8 The leg fixation component 2 has two sets, and the second connecting mechanism 32 has two second bases 321, which are respectively connected to the two sets of leg fixation components 2. The leg fixation components 2 and the second bases 321 are assembled and fixed during the production process. When using the product, the user adjusts the two sets of leg fixation components 2 to the corresponding height according to the leg position that needs to be fixed. Then, the locking buckles 303 on each base are engaged with the corresponding locking holes 304 on the second connecting component 322 to fix the two sets of leg fixation components 2. This can enhance the stability of lower limb fixation, distribute fixation pressure, reduce the pressure of a single fixation point, ensure the relative position stability of the lower limb and hip, and avoid fracture displacement or joint dislocation.

[0030] In some implementation schemes, see Figure 2 The first base 311 and the second base 321 have inner linings on the side facing the human body. These inner linings are in direct contact with the body; the soft material reduces pressure on the skin, improving wearing comfort and reducing complications such as pressure sores and allergies. They are made of breathable material, promoting heat dissipation and sweat evaporation, reducing discomfort caused by prolonged wear. Furthermore, the inner linings are removable for easy cleaning and replacement, maintaining hygiene.

[0031] In some implementation schemes, see Figure 4 , Figure 5 and Figure 7The side support assembly 3 also includes an adjustment mechanism 33, through which the lower end of the first connecting mechanism 31 is connected to the upper end of the second connecting mechanism 32. The adjustment mechanism 33 allows the first connecting mechanism 31 and the second connecting mechanism 32 to rotate relative to each other, enabling multi-angle adjustments such as hip joint flexion, abduction / adduction; allowing patients to perform multi-angle movements during rehabilitation, avoiding joint stiffness, and promoting early rehabilitation training; the angle locking function ensures fixation stability, taking into account both rehabilitation and treatment needs.

[0032] In one exemplary implementation, see Figure 5 and Figure 9 The adjustment mechanism 33 is a positioning plate locking hip hinge structure. Specifically, it mainly includes a positioning plate and two sets of hinge structures. The positioning plate is provided with a turntable 331 and a locking element 332. The first connecting mechanism 31 and the second connecting mechanism 32 are respectively connected to the upper and lower ends of the turntable 331 in the positioning plate through the hinge structure, so that the first connecting mechanism 31 can rotate relative to the second connecting mechanism 32 to realize the adjustment of the hip joint flexion angle. The locking element 332 in the positioning plate is used to lock the turntable 331 to restrict its rotation. After the hip joint flexion angle adjustment is completed, the relative position of the first connecting mechanism 31 and the second connecting mechanism 32 is fixed. Specifically, both hinge structures employ a helical gear 333 and a worm gear 334. The helical gear 333 is rotatably connected to the turntable 331, and the worm gear 334 is rotatably connected to the corresponding connecting member (first connecting member 312 or second connecting member 322). The worm gear 334 meshes with the helical gear 333. During hip joint abduction / adduction adjustment, the worm gear 334 is rotated to drive the helical gear 333 to rotate, causing the first connecting member 312 or the second connecting member 322 to rotate inward or outward relative to the positioning plate, thus achieving adjustment. Unlike current fixation devices on the market that only limit movement to 5 / 10 degrees, this application, through a hinge structure in conjunction with a positioning plate, enables arbitrary angle adjustment within the angle limitation range, allowing for multi-dimensional and precise dynamic fixation of the hip joint, meeting clinical needs for angle limitation at different rehabilitation stages.
