Description

Technical Field

[0001] This invention relates to the field of orthopedic surgical nursing equipment technology, and in particular to a joint fixation device for orthopedic surgical nursing. Background Technology

[0002] Orthopedic surgery is a medical specialty encompassing trauma and spinal surgery. It specializes in the diagnosis and treatment of various types of finger, palm, and polydactyly replantation, various types of flap transplantation, nerve repair, congenital limb deformities, brachial plexus injuries, and nerve entrapment. In orthopedic nursing care, it is necessary to immobilize the patient's leg joints. Joint immobilization devices are commonly used medical aids in orthopedics, aiding in the treatment of the patient's joints or legs. Patients with leg disabilities who lack movement for extended periods may experience gastrointestinal dysfunction and indigestion. Existing leg immobilization devices offer limited functionality, merely restricting or relieving leg flexion. They fail to assist patients in performing limited leg flexion rehabilitation exercises within a defined range, and the flexion angle is not adjustable, thus lacking any specific therapeutic effect for leg flexion rehabilitation. There is a lack of a device that can effectively immobilize a patient's leg, allowing for real-time adjustment of the flexion angle during training, while also being easy to operate. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a joint fixation device for orthopedic surgical care, so as to solve the technical problems of the existing orthopedic surgical fixation devices having a single function and an inability to adjust the bending angle range. This invention has the advantages of being able to adjust the bending angle range of the fixation device in real time according to the patient's recovery and rehabilitation training process, and being easy to operate.

[0004] This invention is achieved through the following technical solution: This invention discloses a joint fixation device for orthopedic surgical care, including a front fixation brace and a rear fixation brace for fixing the thigh and lower leg of the lower limb; it also includes two symmetrically arranged angle adjustment devices at the docking points on both sides of the front fixation brace and the rear fixation brace; The adjustable angle device includes a connecting component located at the docking point of the front and rear fixed guards. The front and rear fixed guards are connected by the connecting component and rotate at multiple angles with the docking point as the axis. The connecting component has an angle adjustment component on its side and a locking component on its side. The locking component of the angle adjustment component can be used to adjust the rotation range of the front and rear fixed guards about the connection point, or to prevent the front and rear fixed guards from rotating.

[0005] Furthermore, the connecting assembly includes a mounting plate fixed to one side of the front fixed guard by a first connector, and a mounting ring fixed to one side of the rear fixed guard by a second connector. The inner side of the mounting ring and the outer side of the mounting plate are rotatably connected by a protrusion and a circular groove.

[0006] Furthermore, the angle adjustment assembly includes a mounting bracket horizontally disposed on one side inside the mounting ring. A rotating shaft is vertically disposed on one side of the mounting bracket, the upper part of which is rotatably connected to the upper end of the mounting bracket. The rotating shaft is located at the center of the mounting ring. A rotating sleeve is rotatably disposed at the lower part of the mounting bracket. The lower part of the rotating shaft passes through the center of the rotating sleeve and is located below the rotating sleeve.

[0007] Furthermore, the angle adjustment assembly also includes a stop post located on one side of the top of the mounting plate. Two adjustment posts are symmetrically distributed in a circle on both sides of the stop post. The two adjustment posts are respectively connected to the side ends of the rotating shaft and the rotating sleeve through a connecting rod.

[0008] Furthermore, the angle adjustment assembly also includes a first bevel gear located on the outside of the rotating shaft and a second bevel gear located on the outside of the rotating sleeve, and a third bevel gear is rotated on one side inside the mounting bracket, the third bevel gear meshing with the first bevel gear and the second bevel gear respectively.

[0009] Furthermore, the locking assembly includes a mounting cover located on top of the mounting ring. The top end of the rotating shaft passes through the center of the top of the mounting cover and rotates in cooperation with it. Inside the mounting cover, there is a ratchet wheel connected to the rotating shaft at its center. Inside the mounting cover, there is a ratchet bar. The ratchet end of the ratchet bar meshes with one of the ratchet grooves on the outside of the ratchet wheel. The ratchet bar can restrict the rotation direction of the ratchet wheel, allowing it to rotate counterclockwise but not clockwise. The other end of the ratchet bar is rotatably connected to the bottom of the mounting plate.

[0010] Furthermore, the locking assembly also includes a spring horizontally disposed inside the mounting cover, one end of the spring being connected to the side wall of the mounting cover, and the other end of the spring being connected to the side end of the ratchet bar. An opening is provided on one side of the mounting cover, and a lever is provided on one side of the ratchet bar, with one end of the lever passing through the opening and located outside the mounting cover.

[0011] Furthermore, a knob is provided at the top of the rotating shaft, and the outer side of the knob is provided with anti-slip texture.

[0012] The present invention has the following advantages: (1) The present invention achieves two different usage modes through the cooperation of the active angle adjustment component and the locking component. The first mode is the fixed mode, which can limit the angle of the front and rear fixed braces so that they are in a straight and fixed state to avoid passive bending affecting recovery, so as to play a role in correcting the lower limbs. The second mode is the rehabilitation training mode, which can adjust the bending angle range of the front and rear fixed braces with the joints as the axis in real time according to the recovery status and training progress of the patient's lower limbs, so that the patient can perform reciprocating bending training of the lower limbs within a certain bending angle range. As the training and rehabilitation progress, the bending angle range of the front and rear fixed braces is gradually increased, and the rehabilitation training of the lower limbs is carried out step by step.

[0013] (2) The present invention improves the accuracy of adjusting the bending angle range to a certain extent by setting a knob that is easier to operate manually at the adjustment end of the control front fixed guard and the rear fixed guard, and setting anti-slip texture at the knob to prevent slipping during operation.

Detailed Implementation

[0016] The embodiments of the present invention are described in detail below. These embodiments are implemented based on the technical solution of the present invention, and provide detailed implementation methods and specific operation processes. However, the scope of protection of the present invention is not limited to the following embodiments. In the description of the present invention, words such as "front", "rear", "left", and "right" that indicate orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0017] The embodiments disclose a joint fixation device for orthopedic surgical care, such as Figures 1 to 8 As shown, it includes a front fixation brace 1 and a rear fixation brace 2 for fixing the thigh and lower leg of the lower limb; it also includes two movable angle adjustment devices 3 symmetrically arranged at the docking points on both sides of the front fixation brace 1 and the rear fixation brace 2. The movable angle adjustment device 3 includes a connecting component 31 located at the docking point of the front fixed guard 1 and the rear fixed guard 2. The front fixed guard 1 and the rear fixed guard 2 are connected by the connecting component 31 and rotate at multiple angles with the docking point as the axis. The side end of the connecting component 31 is provided with an angle adjustment component 32, and the side end of the angle adjustment component 32 is provided with a locking component 33. The locking component 33 of the angle adjustment component 32 can be used to adjust the rotation range of the front fixed guard 1 and the rear fixed guard 2 about the connection point as the axis, or control the front fixed guard 1 and the rear fixed guard 2 to be unable to rotate. Furthermore, the connecting assembly 31 includes a mounting plate 312 fixed to one side of the front fixing guard 1 via a first connector 311, and a mounting ring 314 fixed to one side of the rear fixing guard 2 via a second connector 313. The inner side of the mounting ring 314 is rotatably connected to the outer side of the mounting plate 312 via a protrusion and a circular groove. like Figure 4 As shown, in this embodiment, the patient's lower limbs are fitted with an anterior fixation brace 1 and a posterior fixation brace 2. The anterior fixation brace 1 and the posterior fixation brace 2 are respectively fitted on the outer sides of the patient's thigh and calf. After adjusting the coverage, the mounting ring 314 and the mounting plate 312 correspond to the patient's joints. When the patient bends their leg with the joint as the axis, the mounting ring 314 rotates on the side of the mounting plate 312, thereby assisting the patient in performing leg bending rehabilitation training. Furthermore, the angle adjustment component 32 includes a mounting bracket 321 horizontally disposed on one side inside the mounting ring 314. A rotating shaft 322 is vertically disposed on one side of the mounting bracket 321 and rotatably connected to the upper end of the mounting bracket 321. The rotating shaft 322 is located at the center of the mounting ring 314. A rotating sleeve 323 is rotatably disposed at the lower part of the mounting bracket 321. The lower part of the rotating shaft 322 passes through the center of the rotating sleeve 323 and is located below the rotating sleeve 323. Furthermore, the angle adjustment assembly 32 also includes a stop post 324 located on one side of the top of the mounting plate 312. Two adjustment posts 325 are symmetrically distributed in a circle on both sides of the stop post 324. The two adjustment posts 325 are respectively connected to the side ends of the rotating shaft 322 and the rotating sleeve 323 through a connecting rod 326. Furthermore, the angle adjustment assembly 32 also includes a first bevel gear 327 located outside the rotating shaft 322 and a second bevel gear 328 located outside the rotating sleeve 323. A third bevel gear 329 is rotatably provided on one side inside the mounting bracket 321. The third bevel gear 329 meshes with the first bevel gear 327 and the second bevel gear 328 respectively. like Figures 3 to 7 As shown, in this embodiment, rotating the rotating shaft 322 drives the first bevel gear 327 to rotate, thereby driving the second bevel gear 328 to rotate synchronously in cooperation with the third bevel gear 329 meshing with it. The rotation directions of the first bevel gear 327 and the second bevel gear 328 are opposite, resulting in the rotating shaft 322 and the rotating sleeve 323 rotating in opposite directions. By controlling the rotation direction of the rotating shaft 322, the two adjusting columns 325 are controlled to move synchronously towards the abutment column 324 around the center of the mounting plate 312, or synchronously move away from the abutment column 324. The rotation angle of the rotating shaft 322 determines the distance between the two adjusting columns 325 and the abutment column 324; a larger distance indicates that the mounting ring 314 can... The larger the range of angles that can reciprocate on the outside of the mounting plate 312, that is, the larger the range of angles that the front fixation brace 1 and the rear fixation brace 2 can bend around the bone joint, the smaller the spacing, the smaller the range of angles that the front fixation brace 1 and the rear fixation brace 2 can bend around the bone joint. This makes it easier to adjust the range of bending angles in real time according to the training process and improve the effect of rehabilitation training. When both adjustment columns 325 are abutted against the sides of the stop column 324, the stop column 324 is restricted from moving, and the mounting ring 314 cannot rotate on the outside of the mounting plate 312. This prevents the front fixation brace 1 and the rear fixation brace 2 from bending around the bone joint, so as to fix the patient's lower limb and play a role in correcting the lower limb. Furthermore, the locking assembly 33 includes a mounting cover 331 located on top of the mounting ring 314. The top end of the rotating shaft 322 passes through the center of the top of the mounting cover 331 and rotates therewith. Inside the mounting cover 331, there is a ratchet 332 connected to the rotating shaft 322 at its center. Inside the mounting cover 331, there is a ratchet bar 333. The ratchet end of the ratchet bar 333 engages with one of the ratchet grooves on the outside of the ratchet 332. The ratchet bar 333 can restrict the rotation direction of the ratchet 332 so that it can rotate counterclockwise but not clockwise. The other end of the ratchet bar 333 is rotatably connected to the bottom of the mounting plate 312. Furthermore, the locking assembly 33 also includes a spring 334 horizontally disposed inside the mounting cover 331. One end of the spring 334 is connected to the side wall of the mounting cover 331, and the other end of the spring 334 is connected to the side end of the ratchet bar 333. An opening is provided on one side of the mounting cover 331, and a lever 335 is provided on one side of the ratchet bar 333, with one end of the lever 335 passing through the opening and located outside the mounting cover 331. like Figure 8 As shown, in this embodiment, by setting a ratchet 332 and a ratchet bar 333 at the rotating shaft 322, when the rotating shaft 322 is used to adjust the bending angle range of the front fixation brace 1 and the rear fixation brace 2, a self-locking function is provided after adjustment. The rotating shaft 322 can only rotate counterclockwise, gradually increasing the bending angle range, and automatically locking after adjustment to prevent the adjusting column 325 from shifting. The rotation has a tactile feedback, making it easy for patients to receive adjustment feedback. When it is necessary to reduce the bending angle range, the lever 335 is moved to disengage the ratchet bar 333 from the ratchet 332, and the spring 334 contracts. At this time, the ratchet 332 is no longer restricted by the ratchet bar 333, allowing the rotating shaft 322 to rotate clockwise, thereby reducing the bending angle range of the front fixation brace 1 and the rear fixation brace 2. Finally, the lever 335 is released, and the ratchet bar 333 returns to its original position, completing the self-locking. Through the cooperation of the above components, a relatively convenient adjustment of the bending angle range is achieved, with high adjustment accuracy and a strong adjustment feedback. Furthermore, the top of the rotating shaft 322 is provided with a knob 4, and the outer side of the knob 4 is provided with anti-slip texture; like Figure 2 As shown, in this embodiment, by setting a knob 4 at the end of the rotating shaft 322 that is easier to operate manually, and by setting anti-slip texture on the knob 4 to prevent slippage during operation, the accuracy of adjusting the bending angle range is improved to a certain extent.

[0018] The principle of this invention is as follows: When using this invention, the patient's lower limbs are fitted with an anterior fixation brace 1 and a posterior fixation brace 2. The anterior fixation brace 1 and the posterior fixation brace 2 are respectively fitted onto the outer sides of the patient's thigh and calf. After adjusting the coverage, the mounting ring 314 and the mounting plate 312 correspond to the patient's joints. At this time, the wearing of this invention is completed. This invention has two usage states. The first is the fixation and recovery mode. In this mode, by moving the lever 335, the ratchet lever 333 is disengaged from the ratchet wheel 332, and the rotating shaft 322 is rotated clockwise, causing the two adjusting columns 325 to abut against the two sides of the stop column 324 respectively. At this time, the stop column 324 restricts the mounting ring 314 from rotating along the outer side of the mounting plate 312. The first type is the rehabilitation training mode. In this mode, the distance between the two adjusting columns 325 and the stop column 324 is adjusted by rotating the rotating shaft 322 counterclockwise. This allows the patient to perform reciprocating bending training of the lower limbs within a certain bending angle range. As the training and rehabilitation progress, the bending angle range of the front fixation brace 1 and the rear fixation brace 2 is gradually increased, allowing for progressive rehabilitation training of the lower limbs.

[0019] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
